| Popis: | Using the in situ technique, the effective degradability of crude protein (CP) of soybean meal was determined in the rumen of sheep given four kinds of hay: alfalfa (AL), bermuda grass, Italian ryegrass (IR) and sudan grass (SG) in order to assess the degradability (dg) values of CP in soybean meal (SBM) determined under different hay feeding regimens. The intake of hay tended to be higher in AL and bermuda grass (BG) feeding than in IR and SG. The rate constants of rumen passage did not differ significantly among the different hay feeding with a tendency to have a higher rate in AL feeding. The degradation rate of CP in SBM tended to be higher in AL and BG feeding than in IR and SG. The effective degradability of CP in SBM determined under feeding of BG was significantly higher than the feeding of other hays. When the range of tabulated dg values of CP was considered, the difference found in the present study was inferred to cause no critical errors in the calculation of the de values of CP in SBM. |
