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.

Serum Alkaline phosphatase (ALP-EC 3.1.3.1), Alanine aminotransferase (ALT-EC 2.6.1.2), Aspartate aminotransferase (AST-EC 2.6.1.1) and Lactate dehydrogenase (LDH-EC 1.1.1.27) enzyme activities were analysed spectrophotometrically using Sigma commercial kits. Significantly higher fluoride ion concentration …
