the aim of this study was to determine effects of different fatty acid profiles on rumen digestion coefficients, some of rumen metabolism parameters and rumen microbial populations. different oils were used as source of fatty acids such as, oleic, linoleic, linolenic, dha and epa. palmitic acid supplemented from a commercial product (bergafat t-300) containing high palmitic acid percentage. res...

1. The paper describes the development and construction of an apparatus for maintaining a normal microbial population of the rumen under strictly controlled conditions over long periods of time. 2. The apparatus is simple to construct and operate. It is possible to do four replicate experiments at the same time. 3. The results of three experiments are given. The experiments showed that when the...

Because of the extensive hydrolysis of dietary proteins in the rumen and the attendant wastage of nitrogen which is absorbed as ammonia across the rumen wall and excreted as urea in the urine, the ruminal synthesis of bacterial and protozoal proteins has a special importance in the nutrition of the ruminant. This paper considers the factors influencing microbial protein synthesis in simple in v...
