Extract

Ration formulation systems require information on nutrient requirements of the animal and reliable values for rumen degradable and undegradable fractions of feed ingredients. Ruminally degraded protein in excess of microbial requirement results in nitrogen loss as ammonia and inefficient nitrogen utilization by ruminants. Protein degradation kinetics of most oilseed meals and some forages have been determined (Sadeghi et al., 2004; Wilkerson et al., 1995), but minimal information exists regarding ruminal protein degradation of pasture forages. The objective of this research was to determine ruminal dry matter (DM) and crude protein (CP) degradation kinetic parameters of eight pasture species.
