Replacement rates in your sheep flock are determined by your ewe losses and your culling decisions. For every ewe lamb you choose to keep, that’s one less to sell.

In this week's podcast our guest, Associate Professor Anne Ridler, discusses the findings from her recent study on ewe wastage in New Zealand sheep farming. Anne’s research found that, on average, 28 to 30 per cent of ewes leave the flock annually in New Zealand. The study aimed to understand when and why ewes exit the flock and how to reduce that wastage.

Let's break those numbers down … say you have 1,000 ewes at mating time:

• At scanning time, of those 1,000, 33 will leave the flock because they’re dry.

• Before set stocking, another 18 ewes will go due to non-reproductive reasons such as low BCS and 17 will die in this time. So, of your original 1,000, you have 932 left by the start of lambing.

• Lambing is the highest risk period, with two-thirds of your losses occurring during this period. The average is 3.7 per cent. So, that’s another 37 ewes leaving the flock up until mid-lactation/docking, leaving you with 895 ewes.

• If you decide to cull wet-dries at lamb-marking, the average is 3.8 per cent, meaning another 38 ewes leave the flock, reducing your number to 874. However, another 33 ewes exit the flock between docking/tailing and breeding of year two, some of which will be wet/dry (on average, across all the farms), some will be culled for other reasons and some will die.

• Then, post-weaning, based on udder issues, age, teeth or other decisions, farmers choose to cull, on average, 15.4%. That leaves you with 708 ewes and so 292 replacements need to enter the flock to get back to 1,000 for breeding.

Whilst these numbers might seem a bit confronting, they give a great insight into how you can reduce the number of replacements you require.

With most losses occurring during lambing, Anne suggests this could be an area to focus on. Feeding ewes well during pregnancy to avoid metabolic issues is a big part of keeping your ewes alive. But there are other things you can do, such as paddock audits and cast beats.

Mark and Anne also discuss other options such as keeping wet-dries and putting them to a terminal ram.

We would be interested to hear what you base your culling decisions on. Is it age? Do you give your wet-dries a second chance? Let us know.

The study this information was derived from was funded by the Massey-Lincoln and Agricultural Trust and done in collaboration with Lincoln University.

In this current climate, should you be looking for ways to save money on farm? Or should you be looking at upping your production to cover rising costs?

This week on the Head Shepherd podcast, we hope to answer those questions for you.

Our guest this week, Tim Leeming, is well known for his precision lambing and we’ve had him as a guest on the podcast before (go check that one out here).

In this episode, Tim discusses his strategies for farming success. “When it comes to your production system - when it comes to understanding what drives that in your business - whether you've got paddocks that need to be subdivided, whether you've got soil fertility that needs improving, pasture composition that needs improving … If you're a good farm manager and have a reasonable base knowledge of how the job rolls … it's not rocket science.”

Tim and Ferg discuss the mindset behind cutting costs vs upping production. While the current advice may be to not join ewe lambs or containment feed, Tim believes in identifying where profit margins exist for a job done well. “If you do a bad job, of course, the economics of those two things might be pretty ordinary, but if you do it well, the margins are there. They're proven margins. We've seen it,” says Tim.

Tim emphasises the need for clear targets and disciplined execution. “We've got evidence of it, that if you manage your nutrition right in ewe lambs and hit these targets and do all the right things, guess what, you'll get a bloody good result, and those sheep will pay you dividends for the rest of their life on your farm because you've done that well.”

Discipline is a big theme throughout this week's podcast, with Tim collecting data when the opportunity presents itself (for example, ewe body condition when ewes are in the yards). “If you think about a mob of ewes, for instance, and how many times that they might visit the stockyards over the year. There are probably at least eight times in a year that those animals will be in a yard facility and generally, they will be going up a drafting race or drenching race or through a sheep handler,” he explains.

For Tim, consistently doing the small things well sets a foundation for long-term success. “It's a two, four, five-minute job to get a line in the sand on where that condition score of that mob is at that particular time. I'm like a dog with a bone. I’m very, very persistent on making sure that we record that, every time we're bringing those livestock in the yards,” says Tim. “It’s so important in your decision-making and your management. So, you know, that is a discipline thing.”

Tim has a huge passion for farming and there are some great takeaways from this podcas

Our guest on the podcast this week is Bonnie Skinner.

Bonnie is the CEO of Sheep Producers Australia (SPA), a levy board that advocates for a better future for Australia’s sheep industry. They do this in a multitude of ways: connecting farmers, consumers and government bodies. They advocate for better outcomes for farmers and direct levy investments towards research, development and industry services.

In this episode, Bonnie and Mark discuss the current challenges faced by the industry - be it artificial proteins, climate change or getting new entrants into the industry - and also what the future holds for lamb and wool producers.

It’s not all doom and gloom, explains Bonnie: “In terms of providing that light on the hill, there is an immense opportunity for lamb as a protein, if we can continue to meet the needs of our consumers.”

“Of course, we are already world-renowned for a high-quality, very consistent product in the industry. We know we can continue to improve on that. But what is the customer willing to pay for? How much room is there to really drive that price up, particularly at a retail level?” These are the questions that SPA are asking, and working towards answering, with industry support.

Another issue faced by the industry is the uptake of new technologies and practices. One example being scanning for multiples. Despite the evidence that it will improve profitability and production on-farm, only 42% of Australian producers scan their ewes and, of these, 69% scan for dry, single and multiple foetuses.

“We've got 10-15% of producers at the top, the early adopters. They are taking up all of these opportunities,” explains Bonnie. “Then we have a good subset of producers underneath that, who are interested [but are not taking the next steps towards adoption]. How do we encourage producers to take up these practices?”

In this podcast, Bonnie explains the scope of SPA’s work for the industry: from identifying required research, right through to farmer implementation, and everything in between.
