1. There are several enzyme systems for fixing ammonia in the ruminal bacteria that are critical for microbial protein synthesis. If the microbes were genetically engineered to only possess the one that worked at the lowest ammonia concentrations what are the implications for microbial protein synthesis?
Ø The Factors affecting microbial protein systhesis are nitrogen concentration,rate of nitrogen,nitrogen sources, carbohydrate degradation,carbohydrate sources ,dry matter intake,synchronization of nitrogen and simultaneous release of energy.
Ø Ruminal microbial protein synthesis requires adequate amount of nitrogen for maximum efficiency.
Ø When the nitrogen concentration is low uncoupled fermentation may occur. As a result of this fermentation without ATP use occur.
Ø In order to get maximum microbial growth energy and nitrogen availability must be balanced.
Ø Several studies reveal that increasing crude protein in basal diet may increase microbial protein synthesis.
