Extract

In Iran milk production, in dairy cows, is based mainly on intensive systems in which cereals and industrial by-product are the most important source of nutrients. So, high digestible protein feeds are often desired for supplementation of high producing dairy cows to meet their amino acid requirements. Incubation of feeds in nylon bags in the rumen of fistulated ruminants have been used to evaluate the extent of digestion. In addition, the mobile bag technique has been used to measure intestinal digestibility of undegraded dietary protein and intact feed protein (Mesgaran, 2002). The work described in this summary assessed the digestibility of dry matter and protein, using ruminal and intestinal mobile nylon bag technique, of some tropical (Iranian) feeds used in dairy cow diets.
