Manage the energy balance but do not forget the calcium

Ewe around lambing

Ewes carrying twins or triplets require a higher energy intake to support the lambs, but at the end of sheep gestation, the lambs take a lot of space, allowing less space for the rumen. This potentially reduces the intake of feed. On the other hand, ewes carrying a single lamb are at risk of becoming too fat, which also increases the risk of a reduced feed intake after lambing and also increases the risk of lambing problems.

Negative energy balance

If feeding of ewes pre lambing is not optimal, there is a serious risk the feed intake will be below energy requirements. Body fat stores will be used for energy. This can result in metabolic disorders, such as pregnancy toxaemia, also referred to as sheep ketosis.

Calcium metabolism

Due to the start of milk production, calcium requirements rise sharply. A reduced feed intake also increases the risk of low blood calcium levels..
