HI
i have attached a feed plan that i used on the ryelands 2 years ago and all lambed perfectly fine and all sheep where shearlings and the last to lamb was a single and was a bit bigger than the rest but had no problems lambing
there are some bullet points so maybe just adjust if they dont fit you criteria
i got this feed plan before i had scanned the ewes so but it still worked fine
hope it helps and good luck
Feed Ration
Notes:
Feed a 18% protein, 12.5MJ ewe concentrate
Assuming hay is of average quality at 8.5MJ
Ewes are in Body Condition Score (BCS) 3 4
Concentrate feeding to start 6 weeks pre lambing
Not knowing how many lambs ewes are carrying
Offer high energy lick buckets 6 weeks pre lambing
Shearlings are usually not as prolific as older ewes and their cervixes are generally tighter having not lambed before. If you over feed you will have difficulties lambing single lambs. Considering all these factors I would feed each ewe up to 0.5kg/head/day as shown in table below:
Weeks Pre Lambing
Weeks Pre Lambing 6 4 2 1
Amount to feed per ewe (kg) 0.13 0.25 0.4 0.5
This is just a guide that I used you may have to tweak the ration next year if lambs are too big, reduce feed. If lambs are too small/weak or ewes are in poor condition, increase amounts.
Hope this helps
