Effect of Protein Sources on Rumen Microbial Protein Synthesis Using Rumen Simulated Continuous Culture System
A rumen simulated continuous culture (RSCC) system was used to study the influence of supplementation of the three different types of protein sources such as urea, casein and soy protein on rumen microbial synthesis in terms of rumen microbial synchronization. The urea treatment showed the highest pH value. Ammonia nitrogen concentration was rapidly increased after feeding and not significantly...
متن کاملThe effect of rumen degradable and rumen undegradable intake protein on feedlot performance and carcass merit in heavy yearling steers.
A total of 432 crossbred yearling steers (395 kg +/- 6.35) were used in a randomized block experiment to study the effects of rumen degradable intake protein (DIP) and rumen undegradable intake protein (UIP) concentration on feedlot performance and carcass merit. The 6 dietary treatments used for this study included 1) a 10.5% CP diet with 5.1% UIP and 5.4% DIP (DIP5); 2) an 11.5% CP diet with ...
متن کاملThe requirements for rumen-degradable protein per unit of fermentable organic matter differ between fibrous feed sources
Ruminant feed evaluation systems use constant minimum requirements of rumen-degradable protein (RDP) and often relate this to apparently degradable organic matter (OM). However, studies with tropical forages indicate that RDP: apparently degraded OM might not be constant across high-fiber diets. This was tested with semi-continuous ruminal cultures (Rusitec) using dried contrasting low-protein ...
متن کاملSlime from the Rumen of Cattle
Previous work has shown the percentage of encapsulated bacteria increased when cattle were placed on a feed-lot bloat type diet (Jacobson et al., 1957) and a recent investigation has shown Streptococcus bovis and Peptostreptococcus elsdenii increases in numbers as the onset of bloat symptoms occurred in cases of feed-lot bloat (Gutierrez et al., 1959). Slime produced by ruminal microorganisms i...
متن کاملThe effect of dietary rumen degradable protein content on veal calf performance
The objective of this study was to determine the undegradable dietary protein requirements of veal calves. Two experiments were carried out with Holstein bull calves from 3-10 days of age until slaughter at 20 weeks of age. Both experiments were divided into starter and finishing periods. Calves were offered starter pellets on an ad lib. basis from seven days of age. Diets were formulated to be...
