Microbial protein supply from the rumen

摘要: Abstract This paper considers the theory, assessment and prediction of microbial protein synthesis in rumen. The difficulties techniques for assessing synthesis, as well complexity rumen ecosystem, have limited progress. Inconsistencies literature undermine value incorporating advanced models into rationing schemes limit exploitation an important resource ruminants. gives examples situations which particular factors significant effects on but moves to discuss development new less-invasive approaches estimating synthesis. latter attraction offering in-built technology transfer through diagnostic tests, based samples milk or urine. Some these offer a description function that is less rigorously quantitative (in terms synthesis), more usefully qualitative populations, substrates interactions).
