Our guest this week is veterinarian Enoch Bergman. Originally from the USA, Enoch arrived in Australia in 2003. He fell in love with the people, the landscape and the agricultural innovation of Esperance, Western Australia and has been there ever since.
Enoch is passionate about improving the performance of heifers and the use of fixed-time artificial insemination (AI) in commercial breeding programmes, and shares that passion with us today. He explains the process of synchronising heifers and the positive outcomes for conception rates, calving ease, calf and heifer survival, weaning rates and rebreeding rates. He also discusses the economic analysis of integrating fixed-time AI versus natural mating, including the cost of bulls, labour and the value of pregnant heifers.
Enoch is also involved with a Producer Demonstration Sites (PDS) programme that aims to encourage the uptake of fixed-time AI. The PDS showed that using fixed-time AI reduced dystocia, calf mortality and heifer mortality. It also improved weaning weights and re-breeding success. Enoch also discusses the benefits of early and short heifer joining and the potential challenges with bull longevity.

00:00:42.929 --> 00:00:43.951 Welcome back to Head Shepherd.
00:00:43.951 --> 00:00:50.829 This week we have Ennard Bergman on the show, who is entertaining and very educational, so I'm sure you're going to enjoy that.
00:00:50.829 --> 00:00:57.426 Before we get underway, we've released another couple of articles over the last couple of weeks, so I just wanted to bring your attention to that.
00:00:57.426 --> 00:00:59.787 Firstly, Sophie, you've written about when to wean.
00:01:00.520 --> 00:01:39.108 Yeah, so weaning for me is one of my favourite topics, and sheep, I think, are a mix of artificially rearing sheep and trying to get them off milk powder as fast as possible and also, if one can have a favorite sheep graph, my favorite sheep graph is the one which looks at pasture intake versus milk intake of a lamb over the first sort of 16 weeks, and that is probably one of the graphs that got me hooked into data and science and just, yeah, it really shows that when you wean lambs has quite an impact on various things, I guess, and be it your cost of production or be it the future performance of the animals, be it the lambs or the ewes.
00:01:39.108 --> 00:01:51.378 Yeah, I thought I'd like write a little article, seeing as people are probably thinking about when they should be weaning and, yeah, hopefully give you some insights so you can make that decision yourself a bit more educatedly.
00:01:52.400 --> 00:02:00.134 So yeah, and I've also written an article which has just gone out over just before the weekend, and that was on bending the growth curve.
00:02:00.134 --> 00:02:11.990 So looking at, I guess, that whole question which is always out there in both cattle and sheep mature weight of either cows or ewes Obviously we want early growth in most systems, but we don't want those sheep to get too, or sheep and cattle to get too big.
00:02:11.990 --> 00:02:21.712 So I've talked about sort of yeah, I guess what we know about that so far and why it's important to keep selecting sheep and cattle down that road.
00:02:21.712 --> 00:02:24.722 Right, we'll get underway with this week's show.
00:02:24.722 --> 00:02:25.782 Enoch Bergman is.
00:02:25.782 --> 00:02:28.606 We've also got a YouTube video on this episode.
00:02:28.606 --> 00:02:32.091 So if you want to sort of watch along, then jump on.
00:02:32.091 --> 00:02:40.269 He's got a slideshow that we delivered as we went through this interview, so you might actually get more value out of watching on YouTube than listening in the vehicle.
00:02:40.269 --> 00:02:44.948 It's worth listening to as well, but you'll definitely get a little bit more if you watch the slides at the same time.
00:02:44.967 --> 00:02:46.069 Uh, he's a.
00:02:46.069 --> 00:02:49.862 He's a really great fellow to chat with and I think you're really going to enjoy.
00:02:49.862 --> 00:02:51.066 Enjoy this show.
00:02:51.066 --> 00:02:53.230 It's around artificial insemination of heifers.
00:02:53.230 --> 00:02:57.187 So fixed ai in heifers and the economics around that.
00:02:57.187 --> 00:02:58.409 He's done a lot of work on that.
00:02:58.409 --> 00:03:01.423 He's also uh, you can chase his youtube channel as well.
00:03:01.423 --> 00:03:10.622 He's uh, he's got heaps of viewers on there, if you like, seeing abscesses popped and that sort of crazy stuff which most people do, unfortunately, for whatever weird reason.
00:03:10.622 --> 00:03:14.371 Um, he's got some pretty, uh cool vet stuff going on as well.
00:03:14.371 --> 00:03:15.941 I think over 100 000 subscribers.
00:03:15.941 --> 00:03:19.931 So, um, yeah, he's certainly certainly a bit of a star on youtube as well.
00:03:19.931 --> 00:03:23.605 So you might you'll stumble across him if you jump on our YouTube channel as well.
00:03:23.605 --> 00:03:25.610 But, yeah, we'll get underway with this week's show.
00:03:26.491 --> 00:03:29.866 Hi guys, sophie here, just a little note from editing.
00:03:29.866 --> 00:03:39.030 The first five minutes of the podcast have some audio disturbance in it, which I've tried to fix, and this is the best I could do.
00:03:39.030 --> 00:03:43.891 But yeah, after the five-minute mark it disappears completely and it's just your normal podcast.
00:03:43.891 --> 00:03:48.419 But yeah, bear with us for the first five minutes and we'll be away.
00:03:48.941 --> 00:03:50.793 Welcome to Head Shepherd Anup Bergman hey.
00:03:51.276 --> 00:03:51.840 Mark, how are you going?
00:03:52.140 --> 00:03:54.506 Good mate, awesome to have you along and thanks very much for your time.
00:03:54.506 --> 00:04:04.151 I've been watching your work for lots of years now and you had your PDS around fixed-time, ai and heifers and sort of a lot of work on the economics of that.
00:04:04.151 --> 00:04:10.171 So that's going to be what we want to talk about today, but we might just start off how you ended up living the dream in Esperance.
00:04:11.241 --> 00:04:12.325 Man, I am living the dream.
00:04:12.325 --> 00:04:19.629 So yeah, I grew up in a little town of nobody out in eastern Colorado, full of lovely people, but there just weren't many of them called Wild Horse.
00:04:19.629 --> 00:04:26.622 It was 12 people growing up it's now down to five and I went to uni.
00:04:26.622 --> 00:04:28.610 To try to be able to come back and help my friends and family was the plan?
00:04:28.610 --> 00:04:40.716 Got into vet school, finished vet school and in the process realized that there was a much bigger world out there, kind of went home and ag had kind of slipped more towards total crop, so a decline of running cattle out that way.
00:04:40.716 --> 00:04:47.630 So I thought, heck, I'll just go check out Australia for a year and then I'll come back and figure out where I want to live and set my resume over.
00:04:47.711 --> 00:04:53.492 And a good fellow down here, david Swan at Swan's Vets, got a hold of my resume and said hey, come, throw your hat in the ring.
00:04:53.492 --> 00:04:56.988 So I applied for the job and he hired me and I flew straight here.
00:04:56.988 --> 00:05:10.428 That was back in 03, mark, and after a year or two I was going to either go to South America or head north, because that's what I thought I was getting into.
00:05:10.428 --> 00:05:15.699 I was a bit surprised down here with all this green grass yeah it blew my mind really and I said to Swanee I think I'm going to head off, he said would you love me to stick around?
00:05:16.000 --> 00:05:17.880 I said, well, look, I've never intended to work for somebody my whole life.
00:05:17.880 --> 00:05:19.983 If you let me buy into the business here, I'll stay here until I'm dead.
00:05:19.983 --> 00:05:22.845 So he said, rightio, and I bought into the business.
00:05:22.964 --> 00:05:26.047 And yeah and the reason I've stayed is Esperance is magic.
00:05:26.226 --> 00:05:34.173 These beautiful beaches, some of the best in the world, so much to do, but the reason I really stay is because of the people and the animals that they look after.
00:05:34.252 --> 00:05:34.653 So it's just.
00:05:34.653 --> 00:05:36.194 I've got new friends and family.
00:05:36.194 --> 00:05:39.997 The farmers down here are just so keen to adopt innovation.
00:05:39.997 --> 00:05:46.831 Like, we're one of the last places in Australia to be given out with conditional purchase.
00:05:46.831 --> 00:05:48.279 I think the last block here was released in 87, remarkably.
00:05:48.279 --> 00:05:50.485 I mean, that just blows the mind, doesn't it?
00:05:50.485 --> 00:05:51.901 Yeah, so it's a real.
00:05:51.901 --> 00:06:09.069 A lot of these guys were doing it tough in South Australia and hopped in their 9Gs and came across the Dusty Nullarburn and set up down here and we're able to, you know, create a life for themselves and their future progeny, and so the town's really humming and these guys just love innovation.
00:06:09.069 --> 00:06:11.906 Yeah, that's me in a nutshell.
00:06:12.649 --> 00:06:15.391 Excellent, so obviously well vet trained.
00:06:15.391 --> 00:06:17.279 And then through that.
00:06:17.319 --> 00:06:18.389 Yep went to Colorado State University.
00:06:18.389 --> 00:06:20.702 Yep Did a food and medicine internship.
00:06:20.702 --> 00:06:23.350 A little bit of extra post-doctorate work, mark.
00:06:23.589 --> 00:06:24.793 Yeah, right on, excellent.
00:06:24.793 --> 00:06:28.230 And then obviously getting into AI is a natural progression.
00:06:28.230 --> 00:06:35.086 But yeah, I guess, maybe talk us through maybe the precursor to the PDS and then the PDS itself.
00:06:36.079 --> 00:06:49.266 Well, when I first arrived in Esperance, a lot of my producers when I would go preg testing for them we would find that their heifer pregnancy rates were excellent, their cow pregnancy rates were acceptable.
00:06:49.266 --> 00:06:51.391 But their first calver rates were pretty low.
00:06:51.391 --> 00:07:03.120 And when I started querying them about what they were doing the practice at the time mostly for most of my clients what I got here was they would join their heifers for the same period of time that they joined their cows.
00:07:03.120 --> 00:07:04.723 I said, look, put the bull out the first of June.
00:07:04.723 --> 00:07:12.963 And we put them in, for some guys even up to three months, quite a few producers actually.
00:07:12.963 --> 00:07:18.521 And so I kind of started exploring that with these guys and they would say, wow, you know, heifers, they do a poor job, they produce crappy little calves and they struggle to get back in calf.
00:07:18.521 --> 00:07:20.444 And I said, well, it's not really the heifer's fault.
00:07:20.444 --> 00:07:23.069 You've kind of set them up to fail a little bit in that.
00:07:23.069 --> 00:07:28.677 You've got to realize that heifers require more time after they calve to prepare their uterus for that next pregnancy.
00:07:28.677 --> 00:07:32.228 So why don't you try joining those heifers a little bit earlier and a little bit shorter?
00:07:32.228 --> 00:07:37.237 So I started getting a bit of success in that because guys would see the pull through of you know, the calves.
00:07:37.439 --> 00:07:38.762 Heifers calved in a tighter window.
00:07:38.762 --> 00:07:39.663 They're a little bit earlier.
00:07:39.663 --> 00:07:47.574 Heifers don't produce as much milk, so the calves fit in a little bit better If they prime the system where they only expected to get about 80% of them pregnant.
00:07:47.574 --> 00:07:50.850 Those other 20% could be sold before they cut more teeth.
00:07:50.850 --> 00:07:52.807 So they're reasonably valuable animals.
00:07:52.807 --> 00:07:56.550 And then those heifers had exceptional conception rates the following year.
00:07:56.550 --> 00:08:03.730 So then, to try to push that a little bit further, we started sinking them with two shots of prostaglandin at the front end, and it would be two or three weeks ahead of the cow mob.
00:08:03.730 --> 00:08:16.009 We could, uh, we could, run them at five percent bulls with two shots of prostaglandin, and then we could pull some bulls back below into the cows and we could get some pretty nice conception rates in a four week or a seven week mating with that methodology.
00:08:16.048 --> 00:08:18.343 So then we got, and then we had guys having cabin trouble here and there.
00:08:18.343 --> 00:08:21.629 So then we thought, well, heck, if we're going to synchronize them, why don't we capitalize on that synchrony?
00:08:21.629 --> 00:08:32.970 So I started implementing or integrating fixed time AI in these heifer mating programs and, man, it was just started to kick ass, like once people did it and they had that super tight calving.
00:08:32.990 --> 00:08:39.129 You know, those first 21 days that when a heifer would cycle, instead condensed over a single day and they just get this big slug of calves.
00:08:39.129 --> 00:08:47.514 And then the caveat to that is we, we, you know we went out there and that's when the curve benders were just starting to come about and first bull we used was bull, called final answer, who they eventually cloned.
00:08:47.514 --> 00:08:50.797 He was such a cool bull and so he was like negative eight on gl.
00:08:50.797 --> 00:08:54.692 So he's about eight days early and he was low birth weight and high weaning weight.
00:08:54.692 --> 00:08:56.921 So we could, we could, we could have our cake and eat it too.
00:08:56.921 --> 00:08:58.403 You get these calves on the ground a little bit early.
00:08:58.403 --> 00:09:06.212 Or again, we can get them nice and small when they hit the ground, because they're kicked out of bed early and then they would grow like steam and uh and produce a wiener.
00:09:06.212 --> 00:09:18.422 That um, that in many cases, because of the fact that we joined a little bit early, because of the fact that shorter gl and because of those ebvs for growth, those calves were actually better than the calves out of their cows and that really started to open people's eyes.
00:09:18.442 --> 00:09:24.092 Because the man, the mantra of many of my producers was you don't keep heifers out of your heifers, you know they just do a poor job.
00:09:24.092 --> 00:09:26.356 I'm like, well, who's your best genetics?
00:09:26.356 --> 00:09:27.899 And if it isn't your heifers, you're going backwards.
00:09:27.899 --> 00:09:32.571 And but what we're doing is we're terminally crossing our heifers to poor genetics.
00:09:32.571 --> 00:09:37.840 And then that those progeny which we were outing we were getting discounted because that you know they were.
00:09:37.840 --> 00:09:41.667 They were smaller because we're using really safe, low weaning white bulls.
00:09:41.667 --> 00:09:49.128 Who, who often was the caveat to you know the prerequisite to have low birth weight before curb benders became available, mostly driven by gestational length.
00:09:50.350 --> 00:10:00.403 So we just really turned everything on their head and said let's keep heifers out of our heifers, which is awesome because then it frees us up to to terminally cross some of our older cows, you know, some of those older girls with older genetics.
00:10:00.403 --> 00:10:04.470 We can terminally cross those for profit, profit, whether we bring in a euro or something like that.
00:10:04.470 --> 00:10:08.177 So it just creates all this great flexibility within the system and um.
00:10:08.177 --> 00:10:09.842 So we're kicking butt, doing stuff.
00:10:09.842 --> 00:10:15.368 And then mla came up with their producer demonstration sites as a program, which I just love.
00:10:15.368 --> 00:10:22.450 It's just a great way for um producer groups to get one, get a little bit of a bit of a profile like our group, a sheep and beef, you know.
00:10:22.450 --> 00:10:31.226 It's been really good for our group and and also to find something that you're doing well and to help disseminate that information to a wider audience, and so it's just been a dream run.
00:10:31.226 --> 00:10:34.147 So I'd love to tell you about that PDS Mark, which I reckon is why you called.
00:10:35.419 --> 00:10:36.826 You're on to it, my friend.
00:10:36.826 --> 00:10:38.405 Yeah, that's exactly what I want to hear about.
00:10:40.126 --> 00:10:41.769 Got any questions for my little wind-up?
00:10:42.729 --> 00:10:53.457 No, no, that's awesome and yeah, and I think we're looking here forward to hearing the spiel on the PDS and we'll ask questions as we go.
00:10:53.457 --> 00:11:00.446 But, yeah, if you want to launch into it, and for those listening, we are recording the visuals as well, so they'll be somewhere on YouTube.
00:11:00.446 --> 00:11:10.269 You better find this as well if you want to actually watch, but if not, just listen along and we'll make sure we make it a good Audible experience as well.
00:11:11.039 --> 00:11:17.947 Hey, mark, about three or four months ago I got a button off YouTube, so I've got a YouTube channel called Enoch the Wanker.
00:11:17.947 --> 00:11:21.279 I mean sorry, enoch the Cow Vet, excellent, so we'll load on your channel.
00:11:21.279 --> 00:11:23.892 I hit my 100,000 subscribers, so that's pretty cool, all Excellent, so we'll load on your channel.
00:11:23.913 --> 00:11:25.480 I hit my 100,000 subscribers so that's pretty cool, all right.
00:11:26.782 --> 00:11:28.970 Let's get rocking how many subscribers 100,000.
00:11:28.970 --> 00:11:32.700 I got 122, I think oh yeah, 122,000.
00:11:32.700 --> 00:11:34.787 Yeah, but they give you a button when you hit 100,000.
00:11:35.008 --> 00:11:37.263 Yeah, right, we're well off the button.
00:11:37.303 --> 00:11:40.172 They're on the screen.
00:11:40.172 --> 00:11:46.500 Let me walk you through this pds, so producer demonstration sites bloody brilliant.
00:11:46.500 --> 00:11:55.755 So every time an animal goes to the kill floor, you know five dollars goes into a bucket and that bucket gets disseminated out for the benefit of all of us that produce protein.
00:11:55.755 --> 00:12:00.327 Um, and I just think the pds program was a great one, really good one.
00:12:00.327 --> 00:12:00.629 It helped.
00:12:00.629 --> 00:12:07.802 I think it helped kickstart a lot of producer groups because, as I say when I give these talks, you know, use your local producer group if you've got something you love doing that you think will help other farmers.
00:12:07.802 --> 00:12:12.004 But if you, if you don't have a producer group, bloody bank, make one um.
00:12:12.004 --> 00:12:18.381 So essentially, um for this pds um, the producers that were involved had to be people that hadn't previously ai.
00:12:18.381 --> 00:12:27.394 So what we did is I had probably about half the district ai in their efforts, but I had a few guys and some of the guys were pretty big guys that were like, ah, I don't really see the value, oh, it looks expensive.
00:12:27.394 --> 00:12:30.802 You know, they had all sorts of reasons why they didn't want to do a lot of work, a lot of effort.
00:12:31.443 --> 00:12:41.047 And so when, when we, when we successfully applied for the PDS, we approached some of those farmers and I was like, hey, look, you know, give it a crack.
00:12:41.047 --> 00:12:45.294 So it was real simple, like, what we wanted is no bias or minimum bias.
00:12:45.294 --> 00:12:47.668 So we just enrolled heifers.
00:12:47.668 --> 00:12:49.105 So we essentially hijacked heifers.
00:12:49.105 --> 00:12:56.764 So these guys, to give you the story, so the PDS application process by the time we got it done, it was right on the point of the bulls getting ready to go out.
00:12:56.764 --> 00:13:01.008 And so we hit up these farmers and said, right, you've already got your bulls to put over your heifers.
00:13:01.008 --> 00:13:02.568 Uh-huh, hey, how about this?
00:13:02.568 --> 00:13:04.429 Let's hijack half those heifers.
00:13:04.450 --> 00:13:07.172 So what we did is based on the last digit of the ear tag odds and evens.
00:13:07.172 --> 00:13:25.756 We took half the heifers out and then they got synchronized and they got AI'd on the same day that the bulls that they already had organized, that they'd already purchased for the job, so there's no bias there went out with the other heifers and and then we managed them, um, identically and just measured stuff, which is pretty cool.
00:13:25.756 --> 00:13:32.744 So, um, yeah, there are 15 sites and there's around two and a half thousand heifers enrolled in the study, so it's got a reasonable degree of power.
00:13:32.744 --> 00:13:35.772 Um, so that's our producer group there, a sheep and beef.
00:13:36.621 --> 00:13:40.761 Um, it was called a sheep at the time, but with all the good beef stuff we've been doing, we've added the cattle side to it.
00:13:40.761 --> 00:13:45.812 Um, that's my practice, one One's veterinary services that I'm a partner in, and then meat and livestock Australia.
00:13:45.812 --> 00:13:59.211 We've got a bit of a hand from Veta-Keynal and ABS and Richard White for performance genetics as far as subsidizing some of the products, and in the economic analysis we went back and removed all those subsidies.
00:13:59.291 --> 00:14:01.423 So it was what it would have cost the producer full-time.
00:14:01.423 --> 00:14:02.405 So what was our goal?
00:14:02.605 --> 00:14:05.613 Our goal is to encourage the uptake of fixed-time AI in commercial life-formating programs.
00:14:05.613 --> 00:14:15.706 Obviously, if more producers integrate fixed-time AI, the greater population of cattle in Australia has access to potentially superior genetics and we can all move forward collectively.
00:14:15.706 --> 00:14:19.822 We needed to estimate the cost of integrating fixed-time AI versus natural mating.
00:14:19.822 --> 00:14:22.249 So try to develop, you know, a bit of modeling there on.
00:14:22.249 --> 00:14:23.850 And how do we do that?
00:14:23.850 --> 00:14:33.462 Well, we'd have to capture some fixed time AI costs and we'd have to come up with some bull costs and then try to capture the differences in these outcomes that we get from these two different interventions and then estimate that value.
00:14:33.462 --> 00:14:34.205 So what are we looking at?
00:14:34.205 --> 00:14:51.076 Well, we're going to target conception rate, dystocia rate, so calving trouble, calf and heifer mortality, weaning rates and rebreeding rates, and then we'd pull up there I mean but we'll talk about some stuff later by a guy named Cushman, and what we know is that heifers that are set up to succeed to calve early as heifers and then calve again early again the next year.
00:14:51.076 --> 00:14:54.524 That will carry on for years six, even six, seven, eight years later.
00:14:54.524 --> 00:15:08.081 And then, out of all that information, let's see if we could develop a return on investment of integrating fixed time AI into commercial life or mating programs and I'm not trying to get guys to not buy bulls, I'm just trying to get them to integrate fixed time AI into commercial life or mating programs.
00:15:08.081 --> 00:15:11.951 So for most of my producers they're still buying bulls and they're back in their AI.
00:15:11.951 --> 00:15:16.792 They're just probably reducing their bull requirements over their heifers by about a third.
00:15:19.059 --> 00:15:26.240 One of the things MLA wanted, jeff Neith said look, I'd love to see just to reinforce the importance of critical mating weight.
00:15:26.240 --> 00:15:29.389 So looking at this is just a quick slide on the conception rates.
00:15:29.389 --> 00:15:30.802 We got based on weights.
00:15:30.802 --> 00:15:37.669 So producers had their heifers enrolled and admittedly, sometimes the heifers were quite light and sometimes they're quite heavy and what we saw is what we've seen in the lit.
00:15:37.669 --> 00:15:42.606 We already kind of knew that when given about two thirds of mature cow weight, we can expect a pretty similar outcome.
00:15:42.606 --> 00:15:46.572 So once the if they're under 300 kilos, we saw a reduction in conception rate.
00:15:46.572 --> 00:15:48.975 Interestingly, but it was pretty small numbers.
00:15:49.561 --> 00:16:04.153 Um, if they're really really, really big, we had poor conception rates as poor conception rates as well, and I think that could be have something to do with there's some cool stuff by getting cliff lamb, where if heifers are allowed to get exceptionally fat, they have a memory of that, of that obesity, and it's really hard to get them to cycle.
00:16:04.153 --> 00:16:18.322 It's kind of like if you're driving, if you're driving down the road doing about a you know 110 and come up behind a caravan, it's pretty easy to get around it, to get on a rising plane of speed, but if you're, if you're doing 160 and you come up behind some other bogan doing similar, a similar speed, it's pretty hard to get around them.
00:16:18.322 --> 00:16:30.511 And I think sometimes those big fat heifers I think in my experience with ai, really well grown out, incredibly obese heifers are often hard to um, to get, to achieve good reproductive outcomes on it.
00:16:30.511 --> 00:16:37.763 I think there's a little bit of a lesson there and the stats seem to show it so that's a pretty solid heifer over 425 kilos.
00:16:37.783 --> 00:16:39.145 Oh man, yeah, those are some big girls.
00:16:39.145 --> 00:16:40.889 Yeah, yeah, yeah, that's it.
00:16:40.889 --> 00:16:44.062 Yeah, yeah, a bit of rosy um, anyhow.
00:16:44.062 --> 00:16:51.325 So, so, um, the um, abs provided us a few cool bulls, so these are some pretty, uh, pretty well-known older bulls.
00:16:51.325 --> 00:16:55.369 Landfall a couple of bulls there, keystone, widely used around Australia.
00:16:55.369 --> 00:16:58.142 Uh, broken bow um murder, do kicking.
00:16:58.142 --> 00:17:01.009 Uh command, widely used um in the U?
00:17:01.009 --> 00:17:01.530 S and here.
00:17:01.530 --> 00:17:09.054 And then, uh, richard White, um hooked us up with Aerieville general looking at breed plan figures.
00:17:09.074 --> 00:17:24.606 We got a few of our producers because we just wanted to kind of map out and just highlight the differences in the opportunities when you go and buy AI, and this is one of the arguments I had with not an argument, but some of the discussion around some of the stuff on Beef Central was people would say, oh well, why can't people just go buy these bulls that you're using for AI?
00:17:24.606 --> 00:17:37.083 Well, you can try, but these are elite bulls, these are your unicorns, you know, on the, the crazy hot scale, um.
00:17:37.083 --> 00:17:39.073 So the, the um, these are some different producers, um, and these are the bulls that they purchased.
00:17:39.073 --> 00:17:39.936 So there's all their ebvs um across there.
00:17:39.936 --> 00:17:43.188 And then here's the ai sires that we used in 2017 general leonardo broken bow.
00:17:43.910 --> 00:17:47.704 If we look, at that as a graph and that's a bit messy and kind of hard to kind of see what we're looking at.
00:17:47.704 --> 00:17:51.773 But there's's the three different farms and then there's the AI side, which is the average of their EBVs.
00:17:51.773 --> 00:17:55.089 But let's look at the things that we're concerned with in the context of the PDS.
00:17:55.089 --> 00:18:08.451 So, as far as calving ease and what I try to strategize to do when I AI for my local producers is I'm trying to buy extreme calving ease bulls so I'm synchronizing these heifers for the benefit of synchrony.
00:18:08.451 --> 00:18:15.820 That's my main drive.
00:18:15.820 --> 00:18:19.490 I'm trying to get more of these girls in calf early so they can early again the next year and go on to have an excellent reproductive life.
00:18:19.490 --> 00:18:24.487 But I'm also trying to mitigate dystocia and there's the maternal side of that contribution to that equation and then there's the bull side.
00:18:24.487 --> 00:18:33.131 So if I can chase bulls that are extreme in regard to their calving these EBVs, hopefully I can moderate some of the female genetics which might contribute to dystocia.
00:18:33.131 --> 00:18:41.942 So, as you can see, I mean these guys did a good job with their calving ease direct calving ease daughters, gestation length and birth weight when they when they bought these bulls.
00:18:43.046 --> 00:18:47.320 But we can do better with AI and I think that's that's the, that's the real key.
00:18:47.320 --> 00:18:53.325 You can go to a bull sale but only one guy can buy the top bull we also selected for growth.
00:18:53.325 --> 00:19:06.933 So what we're trying to do is we're trying to get cavities, but we're also trying to get animals that will continue to grow well and the sort of bulls that I love myself are low birth weight, high 200, high 400, maybe cool off at 600 days and then have a moderate mature cow weight.
00:19:06.933 --> 00:19:19.452 You can see that in kind of the percentile rankings here of the bulls that we selected for the PDS, because I don't I'm not a big fan of monster cows, because monster cows have monster requirements, monster appetites.
00:19:19.472 --> 00:19:19.974 Yeah, that's it.
00:19:19.974 --> 00:19:20.297 That's it.
00:19:20.297 --> 00:19:26.664 Got big bellies Get in my belly and then, okay, so we needed to crunch some numbers, all right.
00:19:26.664 --> 00:19:30.428 Oh well, and this is a question I used to ask a lot of farmers hey, what's your bull cost?
00:19:30.428 --> 00:19:32.148 And they go, oh, he cost me six grand.
00:19:32.148 --> 00:19:34.010 I say, yeah, but what is your bull cost?
00:19:34.010 --> 00:19:35.732 They say, well, I told you it was six grand.
00:19:35.732 --> 00:19:37.574 I say yeah, but what's it cost per calf?
00:19:37.574 --> 00:19:40.817 And I used to run these numbers with producers just shooting the breeze.
00:19:40.817 --> 00:19:42.980 So I went on to Beef Central.
00:19:42.980 --> 00:19:50.352 John Condon quoted, in the year of the study, 2017, that the average bull price angus bull was 7 634 bucks.
00:19:50.352 --> 00:20:00.304 So what I say to my farmers is you got to say to yourself their bull mating cost is actually your purchase price, your bull minus the cold value divided by his expected longevity.
00:20:00.304 --> 00:20:10.731 And phil holmes did some stuff um with a number of his producers um showing an angus average 2.7 um joinings before they broke down or were cold for whatever reason.
00:20:11.133 --> 00:20:11.874 So we went with three.
00:20:12.380 --> 00:20:20.969 And I want to quickly point out that in this study, anytime we were given an opportunity to put in an estimate, we always erred on the side of caution.
00:20:20.969 --> 00:20:25.365 We always, if anything, tried to buy us away from the outcome that we're trying to prove.
00:20:25.365 --> 00:20:28.602 So the cold value of two grand, that's a pretty good return for a bull.
00:20:28.602 --> 00:20:41.094 And a reasonable number of bulls don't even make the truck because they're ncv, you know, blown stifle, can't, can't walk or, uh, or horrific penile injury and, um, you know, unable to it has to be euthanized on welfare grounds.
00:20:41.094 --> 00:20:47.790 But so if we look at that, the annual bull annual purchase cost works out to 1878 per year.
00:20:47.790 --> 00:20:49.843 Is the purchase cost distributed over.
00:20:49.843 --> 00:20:54.480 But bulls eat stuff and stuff, and so we can't discount that.
00:20:54.480 --> 00:20:56.065 So what's that worth?
00:20:56.065 --> 00:21:04.672 Well, a bull eats about as much as a cow and a half, and so then we went to the pregnancy rate over the natural mates in the trial of 82%, and we went.
00:21:04.672 --> 00:21:10.804 That time was about $4 per kilo for weaned calves, and then we went with a conservative weaning weight average for the district of $300.
00:21:10.804 --> 00:21:17.023 And that told us that the bull was displacing a potential return for the producer of $1,476.
00:21:17.044 --> 00:21:21.643 Now we add those two numbers together and we get an estimated bull total annual cost of $3,354.
00:21:22.305 --> 00:21:27.964 Then we take that and multiply it, times 3% and that gives us a cost per heifer mated of about a hundred bucks.
00:21:27.964 --> 00:21:28.768 So there you go.
00:21:28.768 --> 00:21:30.935 I mean you could argue and say it's $80.
00:21:30.935 --> 00:21:32.160 You could argue and say it's $120.
00:21:32.160 --> 00:21:35.569 But that's kind of an interesting thing that I think a lot of farmers haven't actually thought about.
00:21:35.569 --> 00:21:40.288 They know they've got a bull that they paid for and they know you're going to sell them later, but what did it cost per heifer mated?
00:21:40.288 --> 00:21:44.003 So in our trial we came up with $100.
00:21:44.064 --> 00:21:47.288 There's In terms of their bull buying.
00:21:47.288 --> 00:21:50.751 So they're averaging 13, 14 grand for bulls.
00:21:50.751 --> 00:21:54.796 So it becomes quite a heavy per ever mating number.
00:21:54.875 --> 00:22:02.972 Yeah, and especially if you go back to some of the stones that were thrown at the PDS and they said, oh, why don't you just go buy a bull like that?
