Abstract

This study was carried out to determine of degradability characteristics of untreated barely grain (UBG) and treated barley grain with autoclaving at 120°C, 5´ (TBG1) and 20' (TBG2), treated barley grain at 100°C, 5´ (TBG3) and 20' (TBG4), using in situ technique in Ghizel sheep’s. The sheep fed diet content 40% alfalfa: 60% concentrate containing 2.9 Mcal kg−1 DM and 14% CP. The incubation times were 0, 4, 8, 16, 24, 36 and 48 h and rumen degradation of cp and DM was measured. The equation of p = a+b (1-e−ct) was used for fitting of dry matter and crude protein disappearance data. The dry matter disappearance of TBG1 and TBG2 at 24 and 48 h were lower than the other treatments (p<0.05). The crude protein disappearance of 24 and 48 h of UBG was more than the other treatment (p<0.05). Treating of barley grain of 120°C (5' and 20') can be decreased ruminal crude protein degradability of barley grain resulting high escaped crude protein into lower digestive tract.
