Crude protein degradation of some energy feeds measured by nylon bag technique

This study was carried out to determine degradability of crude protein (CP), feed value parameters (a., b, a+b and c) and effective crude protein degradability (ECPD) by in sacco (nylon bag) technique for some commonly used energy feeds (barley, wheat, wheat bran) produced in Erzurum province. Three ruininally cannulated Morkarainau rams of 2 years were used in this research. The energy feeds were incubated for 2, 4, 8, 16, 24 and 48 h. Effective degradability were calculated using rumen outflow rate (k) (0.05/h) coefficient obtained from Neway P.C. package program. Results obtained by the nylon bag technique indicated that the crude protein degradability values at 2, 4, 8, 16 and 24 h seem lower in barley than in wheat and wheat bran but wheat grain had higher values at all of the incubation periods except for at 2 h than those of wheat bran and barley. The crude protein degradability values of wheat and wheat bran at 8, 16 and 24 h incubation periods are close to each other.
