Objective
The goal of this class is to discuss deeply and in detail, protein metabolism in ruminants, including ruminal digestion and intestinal nitrogenous compounds of the diet, the absorption of nitrogenous compounds in rumen and intestines, the post absorptive metabolism of nitrogenous compounds, the protein requirements of beef and dairy cattle, NRC and CNCPS protein systems, the balancing of amino acids in diets and the environmental impacts of excretion of nitrogen compounds to the environment.
