Effects Of Some Dietary Factors On Ruminal Microbial Protein Synthesis, M. Aki̇f Karsli, James R. Russell
Effects Of Some Dietary Factors On Ruminal Microbial Protein Synthesis, M. Aki̇f Karsli, James R. Russell
Turkish Journal of Veterinary & Animal Sciences
The effects of some dietary factors, other than source and amount of N and carbohydrate, on the amount and efficiency of microbial protein synthesis are discussed in this review. Specifically, these factors include dry matter intake of animals, forage:concentrate ratio of diets, rate of N and carbohydrate degradation, synchronized release of N and energy from diets, rate of passage, and other factors, such as vitamins and minerals. It seemed that diets containing a mixture of forages and concentrates increase the efficiency of microbial protein synthesis because of an improved rumen environment for the growth of more diverse bacteria species.
