Extract

A large number of studies have been carried out on the effect of level of crude protein in the concentrate supplement on cow performance. However, there is little information on the effect on milk output of different vegetable protein sources fed as a supplement to cows (on grass silage). This experiment was designed to compare the influence of 4 vegetable protein sources in the supplement, soyabean meal, groundnut meal, cottonseed meal and rapeseed meal on milk yield, intake and diet digestibility by cows in early lactation offered grass silage ad-libitum.
