Effect of Silage Digestibility on Concentrate Needs in Late Pregnancy

The infographic details how silage digestibility significantly affects feed value, impacting ewe weight and lamb birth weight during late pregnancy. A 50 g/kg increase in digestibility boosts ewe weight by 6.5 kg and lamb birth weight by 262 g. With a high feed value of 790 g/kg, concentrate requirement is 8 kg per ewe; with a low value of 640 g/kg, it rises to 35 kg. The study included 125 ewes and 1 tonne of feed, with 29 in the study group. Improved feed value enhances flock performance and reduces concentrate needs, but accurate feed value assessment is essential for effective feeding plans. cagsc SheepNet
