Just thought I would make a forum topic about this as it cropped up in chat and thought it might be quite interesting to the wider audience!
"if the sheep come close to the cam, you may notice they have brown round their necks and faces. This is because today we have given them a trough full of neat molasses which they love and it helps to keep their energy levels up now that we are only three weeks away from lambing"
"it also helps to avoid what is known as 'twin lamb disease' when the growing lambs inside their mums sap all the sheeps energy and they become short of calcium and magnesium which sends them into a sort of coma if not spotted in time"
"this is more likely to happen a week or so before lambing and a week or so after lambing when the calcium is being used by the lambs for bone formation and for their milk after lambing. The sheep cant keep up with the demand on their calcium and hence " twin lamb disease" sets in"
The above pic isn't quite our sheep yet but they do like that mollasses :P
