Extract

The efficiency of use of feed protein for milk protein production is very poor, particularly for animals offered conserved forages. Contributing to this is the inefficient capture of rumen degradable N in situations where a readily fermentable energy supply is not available for use by the rumen microbial population. The incorporation of a whole crop cereal into a conserved forage could increase rumen protein efficiency. This experiment was carried out to investigate the milk production of dairy cows offered a conserved forage of a whole crop barley and kale bicrop compared with grass silage, and a mixture of the two.
