The 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 کاملEffect of corn processing on degradable intake protein requirement of finishing cattle.
Three finishing trials were conducted to determine effect of corn processing on degradable intake protein requirement (DIP) of feedlot cattle. In Trial 1, 252 steers were fed 90% concentrate, high-moisture corn-based diets that contained 0, 0.4, 0.8, or 1.2% urea (DM basis) to provide dietary DIP values of 7.0, 8.2, 9.3, and 10.5% of DM, respectively. Nonlinear analysis predicted maximal feed e...
متن کاملExcess energy intake promotes the development of hypoalbuminaemia in rats fed on low-protein diets.
1. A group of rats were given ad lib, a diet with a protein-energy: total energy (P:E) value of 0 . 03. Other animals received the same protein intake (g/kg body-weight per d) as this group, but had their energy consumption reduced to either 90, 80, 70, 60 or 50% of the ad lib. value. 2. The restricted growth rate of rats fed on the P:E--0 . 03 diet ad lib. has been shown to be due entirely to ...
