IMG_6644Our handsome Oxford Down ram Bertie has been enjoying the company of the lovely Jacob Ewes of Stepney City Farm as well as a few of our own ewes. He’s all raddled up and wasted little time! Putting a ram to the ewes now in November should mean lambs will arrive in April if all goes to plan as the typical gestation in sheep is 5 months.

The harness Bertie wears is called a raddle. This holds a crayon which marks the ewes as he services them. These markings allow farmers to keep track of which ewes have been covered and by changing the colour of crayon, when this occurs. By monitoring the marks, we can work out if and when the ewes have come into or gone out of season.

Mudchute Bertie seems to be doing a fine job, so we hope to welcome new lambs in the Spring. If any Oxford breeders are interested in his tupping services, please do get in touch via farm@mudchute.org.

Look at those lovely horns!

Look at those lovely horns!

Here at Mudchute, we are hosting the lovely Biddlesden Warrant. This handsome Whitefaced Woodland ram has a lovely temperament and gorgeous set of horns to match. Even more exciting are his genes. Whitefaced Woodlands are a vulnerable native sheep breed, which means there are only 500 – 900 breeding females in the UK. With such a small population, it is very important to ensure we keep our animals healthy and continue to breed to unrelated stock (no mean feat with so few individuals). With a carefully managed breeding programme and working closely with the RBST and breed societies, we hope to be able to help maintain and develop this beautiful hill breed and are delighted to have Warrant on the farm with us. So far he seems to be a hit with our ladies as well!

You may notice Warrant is wearing a harness. This device is a raddle, which holds a pad of paint or chalk. The raddle lets us know when the ram or tup) “covers” a ewe. Over the next few days you also spot him sniffing at the ewes with his top lip curled back, a behaviour called “flehmen” that helps him detect their hormone levels, which will tell him whether or not they will be receptive to his advances.

Rams are not the only ones who travel for a bit of matchmaking. Two of our Oxford Down ewes have been off to spend some time at Lambourne End with Hannibal the Southdown ram.

All the matchmaking seems to be going well and we hope to welcome lambs in the late spring. Ewes typically give birth after an average of 147 days (about 5 months), but won’t show many outward signs of pregnancy for quite some time as much of the fetal growth takes place in the final 1-2 months of gestation. With a bit of luck, we’ll be expecting at the end of Spring!

Love is in the air for our sheep! That’s right, it’s tupping time on the farm and that means our two stud rams (or tups) are getting to spend a bit of time with a number of our ewes. Frankie the Oxford Down and Billy the Whitefaced Woodland ram are getting to know the girls and will “cover” their respective ewes over two periods of seventeen days. This increases their chances of mating during oestrus, a 30 hour period every 17 days during which the ewes are most fertile.

The rams can detect where the ewes are in their cycle by smelling their hormones. There is an area beneath the upper lip which is particularly sensitive to hormones called the vomeronasal organ. To increase contact between the scents and this area, the boys sniff deeply with their upper lip curled back, exhibiting the flehmen response.

Preparing for the big date(s)

In preparation for tupping, we’ve been pampering the ewes with extra feed and access to our richest grazing to encourage them to release more eggs. Both rams and ewes have also been health checked and had a pre-tupping pedicure.

To help keep track of when our sheep are breeding, both rams are fitted with a harness holding a raddle, which marks the ewes as they mount them. We can change the colour of the raddle, which allows us to see when a ewe has been mounted. If a ewe has lots of colors on her back, it suggests that a ewe did not conceive on the first mating, as she should stop being receptive once pregnant. Likewise, if a ewe shows only the first colour we used, she may have conceived right away and might be among the first to lamb.

Both of our studs are experienced, proven rams, who have already sired many lambs here at Mudchute as well as further afield. Although we didn’t breed our own flock last year, both rams acted as studs, with Frankie at Surrey Docks City Farm and Billy on a private farm. This year, you will also notice a number of Jacob ewes in with Frankie the Oxford ram. These ewes are from Stepney City Farm and will return to Stepney after tupping. We’ll be interested to see whether the Oxford/Jacob lambs will take after their mums or dad.

What happens next…

If all goes to plan, we’ll be lambing in late April next year as ewes typically give birth after a 5 month gestation period (an average of 147 days). Here in the UK, shepherds traditionally tup in November, with tupping around Fireworks night for lambs born around Easter, after the worst of the winter weather. The number of lambs born to each ewe may vary, but both Oxford and Whitefaced ewes typically give birth to either twins or single lambs, although we have had triplets in previous years.

If the ewes do conceive, the fertilised embryo will implant 21 to 30 days after breeding. However, we will not see any outward signs of their pregnancy for quite a few months as most of the embryo’s growth occurs in the final 4-6 weeks before birth.

We’ll keep you posted and our fingers crossed for the pitter patter of little hooves.
