Track 1-08: Improving Quality of Livestock Products to Meet Market and Community Demands
Description
Milk composition is affected by the dietary concentration of crude protein (CP) (Kung Jr and Huber 1983) and minerals such as phosphorus (P) (Wu and Satter 2000). Milk composition has consequent effects on the processing properties of milk (Dillon et al. 1997). The objective of this study was to determine the effects of offering supplementary concentrate feeds differing in CP and P concentration to lactating dairy cows in the early lactation period (Feb-May) on milk yield and composition, and on animal nitrogen (N) and P status.
