Abstract

On-farm assessment indicates that present feeding standards for dairy sheep lead to overestimation in protein requirement. The proposed lowering of the (protein) standards can be justified on both nutritional and economical grounds. The proposed lowering in feed protein allowance will lead to efficient protein use without reducing milk yield. An overestimation of 0.5 kg milk results in 15 to 25% over feeding. Improvements in roughage quality are essential to compliance with organic feed standards restricting concentrate inclusion to 40% of the ration. Economic optimalization of dairy sheep nutrition is possible using Dynamic Linear Modelling (DLM)
