The effects of dipeptidase inhibitor on peptide breakdown and VFA concentrations in rumen of sheep

摘要：

The objectives of this study were to examine the effect of dipeptidase inhibitor (DI) on the concentration of NH3-N, VFA and peptide N in rumen. Four Small-Tailed Han rams fitted with rumen fistula were fed with pelleted diets containing DI of different concentrations at four ten-days experimental periods, respectively. Rumen fluids were taken through the fistula at last two days of each period. The results indicated that DI inhibited the release of NH3-N severely (P＜0.05). In addition, the peptide N concentration increased (P＜0.05) with the increase of DI concentration. However, the VFA concentrations, except propionic acid, were not affected.
