Quote from Gwlaad ... info for farmers .....
Unfortunately for many sheep farmers, this unseasonal weather has come at a time where the ewe’s milk production is at its peak, three to four weeks post lambing, and when energy demands are at their highest.
Generally, an ewe rearing twins will need considerably more energy during this period compared to one week before lambing. Of course her energy requirement depends on her weight, body condition score and the number of lambs she’s rearing. If we take for example a 60kg ewe rearing twins, a week before lambing she will need 16.3MJ of energy. Then during early lactation to produce 2L of milk a day she will need 23.7MJ or 32MJ to produce 3L. (Source: Energy and Protein requirements of ruminants, AFRC 1993)
If there is less than 4cm of grass available, it’s unlikely that the ewe’s needs will be fully met, and in order to maintain the performance of the ewe and lambs, additional feeding will be necessary.
