Ruminal protein degradation and estimation of rumen microbial protein production
Journal Title: International journal of Advanced Biological and Biomedical Research - Year 2013, Vol 1, Issue 8
Abstract
Animal agricultural production systems are major sources of nonpoint pollution affecting quality of water sources. Nitrogen has been identified as the foremost source of nonpoint water pollution and the potential negative impacts of N have become an area of public concern. protein degradation from feed ingredients is an important factor influencing AA supply to the duodenum. Ruminal proteolysis determines the amount of ammonia, AA, peptides, and branched-chain VFA available for microbial growth and proliferation. Carbohydrates are the main components in the dairy ration, comprising roughly 60 – 80% of total dry matter (DM) and could supply to 70% net energy lactation (NEL) for high yielding dairy cows. External markers such as 15N or 35S as well as internal markers such as nucleic acids have been used to determine ruminal microbial protein production.
