Nutrient requirements of the pregnant ewe increase with stage of pregnancy and with expected litter size. Foetal growth takes place principally during the final 6 weeks of gestation. As uterine volume increases with growing foetal size, rumen volume is decreased due to a lack of abdominal space. This can cause a reduction in dry matter intake in late pregnancy as lambing approaches. Even the introduction of supplementary concentrates in late pregnancy cannot always provide sufficient nutrients to the multi-foetal ewe, resulting in mobilisation of maternal body energy reserves to maintain foetal growth. The provision of a high energy feed supplement, available on a self-help basis, allows ewes the opportunity to “top up” their nutrient intakes. This study examined the effect of feeding Extra High Energy CRYSTALYX® (feed lick), containing sugars, oil, protein and minerals, on an ad libitum self-help basis on the performance of housed ewes fed silage and concentrates in late pregnancy and post lambing. This paper reports the final part of a full gestation and post-lambing study, the first stage of which was reported by Chaudhry et al. (2003).
