Low degradable protein supply to increase nitrogen efficiency in lactating dairy cows and reduce environmental impacts at barn level
Generally, <30% of dairy cattle’s nitrogen intake is retained in milk. Large amounts of nitrogen are excreted in manure, especially in urine, with damaging impacts on the environment. This study explores the effect of lowering dietary degradable nitrogen supplies – while maintaining metabolisable...
