A farmer and a vet are embarking on what they declare is the world’s largest progeny testing scheme of wool-shedding Sheep in a quest to breed low-input, low-footprint sheep for UK farmers.

Shropshire sheep and arable farmer Hayden Woolley, and vet Ian McDougall, who gives breeding providers for sheep farmers via his firm, Farmgene, have imported 4 wool-shedding breeds.

They are going to be placing them to the check in Mr Woolley’s outdoor-lambing flock in a bid to provide performance-recorded stud inventory on the market.

The duo met when Mr Woolley’s flock was chosen to offer the majority of embryos for ram breeder Wairere NZ, and Farmgene was contracted to gather and freeze the embryos.

Mr Woolley beforehand had Romney Ewes, however began phasing them out after shopping for EasyCare ewes from the breed’s pioneer, Iolo Owen, seven years in the past.

The motive behind the transfer was to cut back the workload of crutching and shearing sheep, with the wool not even protecting the labour prices related to shearing.

They agreed that EasyCare genetics had enormous potential and will assist UK sheep farmers overcome many future challenges by serving to to chop manufacturing prices.

Nevertheless, they each consider the present breed wants to increase its gene pool to forestall inbreeding, add hybrid vigour and enhance most manufacturing traits.

Breeding programme

Altogether, 1,280 ewes had been synchronised and both artificially inseminated with semen or implanted with embryos from totally different sires representing all the most important wool-shedding breeds from Australia, New Zealand and Nice Britain.

With in depth expertise of the sheep business within the southern hemisphere, Mr McDougall was in a position to make use of his experience to pick the most effective wool-shedding genetics he may discover.

Rams from two flocks had been chosen from the south of Australia as a result of the local weather is much like the UK’s.

“They’re bred to thrive in rainfall of 750-900mm and grass grows for 9 to 10 months of the 12 months,” he explains.

About 1,130 ewes had been artificially inseminated over three weeks and had been then cut up into six teams for repeats to be mated with chaser rams – NZ Wiltshire and high-index UK EasyCare rams.

It’s estimated 70% of ewes held to synthetic insemination.

An extra 600 ewes had been single-sire mated to Exlana rams. As well as, 150 embryos (Australian White cross Nudie and pure Australian White) had been implanted.

The goal is to create two composite traces:

• A wool-shedding maternal sire
• A wool-shedding terminal sire.

At present, the ewes are cut up into two mobs and are on cowl crops and roots.

Two weeks earlier than lambing, which is because of begin in late March for 5 weeks, they are going to be set-stocked on grass fields near the house farm.

“I need to farm them as commercially as doable and let the nice sheep rise to the highest,” says Mr Woolley, including that the sheep won’t be given any preferential remedy.

All lambing might be outside, adopted by rotational grazing on 120ha (300 acres) of parkland cut up into 4 20ha (50-acre) paddocks.

The goal is to boost the dimensions of ewes and make them extra prolific with out adversely affecting lambing capability.

Terminal breeds equivalent to Australian White and Ultrawhite have been chosen to enhance lamb high quality – particularly development, carcass high quality and weight – as a result of a typical criticism of the EasyCare breed is that its lambs are usually not ok in these areas.

“Australian lambs are bought at heavier weights [up to 50kg liveweight], so this can present a superb improve, however ewes from these flocks nonetheless lamb unassisted outdoors,” says Mr McDougall.

Efficiency recording

Every lamb might be recorded within the discipline, with information instantly entered on an iPad utilizing the iLivestock cloud-based programme.

All information might be emailed to Signet and NZ Sheep Enchancment Restricted (SIL) to generate breeding values.

As a substitute of being index pushed, they are going to be targeted on recording quite a lot of terminal and maternal traits.

To make sure steadiness, nothing might be thought-about in isolation.

Mr McDougall explains the rationale behind his idea: “There isn’t a level in 5 years’ time having an EasyCare maternal flock that’s too lean and has outsized lambs.

“The sweetness is that we’re not restricted by breed or a model, so we are able to ‘let the winners win’,” he provides.

Future

Though they don’t intend on including as many sires subsequent 12 months, Mr McDougall is already trying to find rams with a low carbon footprint from New Zealand, and rams proof against worms from Australia, the place enormous strides have been made in these fields.

In New Zealand for the previous 4 years, farmers have been capable of lease moveable methane-recording chambers to assist establish sheep that emit low ranges of methane.

Mr McDougall and Mr Woolley hope to capitalise on this sooner or later by finishing up comparable exams.

“Scale performs an essential half. The extra sheep you possibly can select from – assuming you choose properly – the extra that ought to end in some distinctive animals being bred,” says Mr McDougall.

Nevertheless, he concedes breeding is a protracted sport: “Quick time period, you should be ready to be disenchanted.

Breeding is a journey, and also you by no means get to the top, however if you’re making progress alongside the way in which, that’s what issues.”

In three years, he and Mr Woolley hope to have bred a 3rd composite that may breed year-round to be used in regenerative arable techniques that need to lamb within the autumn and graze cowl crops.

“My most important motivation for this undertaking helps others. I began sheep farming with 60 sheep and I made each mistake recognized to man,” admits Mr Woolley.

“I believe we have now received the reply, and when subsidies go, sheep farmers will want a solution.”
