Latest / The Muster on Hokonui / The Muster- Graham Butcher: Retaining Ewe Body Score
Transcript
- 0:09Speaker 1: This is the muster on Hokanui, Graham Butcher, Farm Consultant,
- 0:12Speaker 1: joins us in studio once again. How are you?
- 0:15Speaker 2: I'm very well indeed, Andy.
- 0:17Speaker 1: It's been a little bit of a correction in the weather.
- 0:19Speaker 1: Next couple of days looks a bit meh, but then
- 0:21Speaker 1: over the weekend, slowly starting to warm up again.
- 0:24Speaker 2: Well, we've had some heavy rainfalls, we've had wind, we've
- 0:26Speaker 2: had sunshine, and we've had All in all, damn sight
- 0:29Speaker 2: better than September.
- 0:30Speaker 1: Anything's better than September. Same old story, right?
- 0:32Speaker 2: Anything's better than September. Too right it is.
- 0:35Speaker 1: Paul Kenyon was on the show last week talking about
- 0:37Speaker 1: you management looking ahead to next season. You went along
- 0:41Speaker 1: to that workshop and you said it was really, really interesting.
- 0:45Speaker 2: It was. It was a three-hour presentation and it seemed
- 0:48Speaker 2: like 20 minutes. It's one of those ones, you know.
- 0:51Speaker 2: Good turnout. It probably... 40 or 50 people there, and,
- 0:55Speaker 2: you know, everyone was busy tailing and getting their tractors
- 0:57Speaker 2: out and what have you, so it was a really
- 0:58Speaker 2: good turnout and a damn good show. I didn't realise
- 1:01Speaker 2: Paul was on, so he's probably stolen some of my thunder.
- 1:05Speaker 2: It's worthy of repeating.
- 1:06Speaker 1: Yeah, well, there you go.
- 1:07Speaker 2: If I am repeating. One of the themes he had
- 1:12Speaker 2: was looking at lambing percentages and is it better to
- 1:14Speaker 2: look at increasing your lambing percentage or increasing your... lamb weights,
- 1:19Speaker 2: particularly your lamb weaning weights and we had some quite
- 1:22Speaker 2: interesting figures up there and he put a series of
- 1:26Speaker 2: graphs up on looking at the impact on cash operating surplus,
- 1:31Speaker 2: which is your cash income less working costs on a
- 1:35Speaker 2: per hectare basis on increasing lambing percentage and what he showed,
- 1:42Speaker 2: going from 133 and 0.5% if we go up to 140%
- 1:49Speaker 2: to 6% increase, the impact on cash surplus was about 7%.
- 1:51Speaker 2: If we go up another 10% to 150% lambing, the
- 1:52Speaker 2: impact is 18% overall. And going up another 10% to 160%,
- 1:53Speaker 2: the overall impact is 26%. Sorry, is this based on
- 1:56Speaker 2: what average weight lambed then, when you're talking about? This
- 1:58Speaker 2: is on.
- 2:15Speaker 2: This is on average weights lamb. On the graph, it
- 2:17Speaker 2: doesn't have what the average weight is. You can presume 18,
- 2:20Speaker 2: 18 and a half K. I think it was a
- 2:22Speaker 2: survey of a number of farms looking at the whole thing.
- 2:26Speaker 1: Right.
- 2:26Speaker 2: So anyway, as lambing percentage increases, the impact on cash
- 2:31Speaker 2: operating surplus is positive. It goes up. But as the
- 2:35Speaker 2: lambing percentage climbs, the rate of increase actually declines because
- 2:41Speaker 2: you get more triplets and all that sort of thing. Right.
- 2:45Speaker 2: Compared to that, starting at 130%, but maintaining your lambing
- 2:52Speaker 2: percentage at around 133%, which is the base starting of
- 2:55Speaker 2: the one I've just talked about, but just concentrating on
- 2:59Speaker 2: your lamb weaning weights. Right, if we go up from
- 3:04Speaker 2: 30 kgs to 33 kgs, maintaining your lambing percentage, the
- 3:09Speaker 2: impact is 17%, nearly 18%, just that one step. If
- 3:14Speaker 2: we go up another three kilos, it's 35%. Another three
- 3:18Speaker 2: kilos on that, it's 52% cash operating surplus, which far
- 3:23Speaker 2: outweighs the gains we can make on increasing our lambing percentage,
- 3:28Speaker 2: even though there is gains there to do it. So
- 3:30Speaker 2: I suppose what I took out of that is as
- 3:33Speaker 2: your lambing percentage rise, the focus has got to shift
- 3:36Speaker 2: onto weaning weights and finishing.
- 3:39Speaker 1: Weights as well.
- 3:40Speaker 2: We didn't talk about finishing weights. Just a change in focus.
- 3:47Speaker 2: As you're increasing your lambing percentage above 140%, the marginal
- 3:51Speaker 2: gains get less and less and less. That's the point
- 3:55Speaker 2: where you've got to start thinking about weaning weights and
- 3:59Speaker 2: lamb finishing weights because the impact on the growth on
- 4:02Speaker 2: your cash farm surplus is actually a lot higher. So
- 4:05Speaker 2: that was quite an interesting theme that came through. And
- 4:08Speaker 2: that sort of ties up with some work I did–
- 4:11Speaker 2: I've been doing it for a couple of years now,
- 4:12Speaker 2: or quite a few years, on what's the sweet spot
- 4:15Speaker 2: for scanning percentage. And funnily enough, it comes out at
- 4:20Speaker 2: about 140%. After that, it declines. At 140%, if you
- 4:25Speaker 2: take all your U deaths, triplet deaths, all those sorts
- 4:30Speaker 2: of losses into account, the sweet spot seems to be
- 4:33Speaker 2: about 185% scanning and 140% tailing, because that's the point
- 4:35Speaker 2: where the kilograms lamb wean actually peaks, and then it
- 4:43Speaker 2: starts to decline a wee bit because of the impact
- 4:46Speaker 2: of triplets and all that sort of thing. So that
- 4:48Speaker 2: was quite an interesting sort of corroboration of what Paul
- 4:53Speaker 2: was saying. The other main theme of the ewe management
- 4:58Speaker 2: one was body condition score. And he was very positive
- 5:05Speaker 2: about how important the body condition score is because it affects...
- 5:08Speaker 2: All sorts of things on productivity on sheep farms affects fertility,
- 5:11Speaker 2: that's the getting in lamb. Scanning percentage, prolificacy, that's the
- 5:15Speaker 2: lambs at tailing. It affects lactation, affects a whole lot
- 5:19Speaker 2: of things and it's a really important thing to do.
- 5:22Speaker 2: But one of the things he did say, there's no
- 5:23Speaker 2: point in having, or very little point, in having ewes
- 5:27Speaker 2: above about 3.5% body condition score. The key is bringing
- 5:32Speaker 2: up that bottom end. That's where the big impact is made.
- 5:34Speaker 1: Consistency through the line. That's what you're aiming for.
- 5:37Speaker 2: Forget about the average. I've been saying that for donkey's years.
- 5:40Speaker 2: An average of 3.5 means half of them are not
- 5:42Speaker 2: up to speed. So 3.5, maybe you have a few
- 5:47Speaker 2: at four at that. Probably that's okay. But bring that
- 5:49Speaker 2: bottom end up because that impacts on a huge number
- 5:53Speaker 2: of profitability trays on the farm. And if you're going
- 5:56Speaker 2: to do good feed management, You've got to actually start
- 5:59Speaker 2: measuring something. What's McGrath doing? What's our cover? Where's it
- 6:03Speaker 2: going to? It's the philosophy that dairy farmers have become
- 6:06Speaker 2: very successful following. So sheep farmers have got to pick
- 6:10Speaker 2: up that and run with it if they're going to
- 6:13Speaker 2: push things ahead. So anyway, it was a really interesting one.
- 6:17Speaker 2: The other really interesting one about body condition score too,
- 6:20Speaker 2: he had a couple of figures on the rates of
- 6:23Speaker 2: attrition in on ewes for low body condition scoring. And
- 6:26Speaker 2: one of the things he said was that for a
- 6:28Speaker 2: five-year-old ewe, the chance of being culled decreased 37% for
- 6:33Speaker 2: every body condition score increase. That's huge. And he said
- 6:38Speaker 2: that sort of figure applied to other age groups as well. 37%
- 6:42Speaker 2: decrease chance of being culled if your body condition score
- 6:47Speaker 2: is pretty good. And the attrition rate in New Zealand
- 6:50Speaker 2: flocks is probably about 30%. By the time your two
- 6:52Speaker 2: ewes go in, by the time they hit after five lambings,
- 6:55Speaker 2: there's very few of them left. They just trickle out
- 6:59Speaker 2: through the whole system. And that's actually a huge cost
- 7:03Speaker 2: for New Zealand sheep farmers.
- 7:05Speaker 1: Just to wrap up as well, South and Rural Support Trust,
- 7:08Speaker 1: we're back catching up with the team and different farmers.
- 7:12Speaker 1: Farm Advisor, when you look back at the last 10
- 7:15Speaker 1: weeks or so as to where we are now, what
- 7:17Speaker 1: words of advice would you say?
- 7:19Speaker 2: I'd say farmers have done a hell of a good
- 7:22Speaker 2: job tidying up. They're still... stuff to do. You see
- 7:25Speaker 2: it lying around the place. Pretty horrendous time a year ago.
- 7:28Speaker 2: But farmers, I think they did a stupendous job cleaning
- 7:34Speaker 2: up and I think the impact has been pretty stressful
- 7:41Speaker 2: on farmers, physical, mental, the whole show. Because that's one
- 7:45Speaker 2: thing we didn't need this time of the year is
- 7:47Speaker 2: that wind that came through.
- 7:49Speaker 1: Nonetheless, the lambs are on the ground now, the ones
- 7:51Speaker 1: that are there and He is hoping to wear something
- 7:53Speaker 1: for this season, eh, Graeme? Good on you.
- 7:54Speaker 2: Yep. Thank you.
- 7:58Speaker 1: Graeme Butcher, Farm Consultant. Once again, Southland Rural Support Trust.

- 8:06Speaker 1: if you need to have a chat as well. So
- 8:07Speaker 1: we're talking about to different farmers and different avenues. And
- 8:11Speaker 1: next week we're going to talk about a few events
