Effect of Aspergillus niger and Trichoderma longibrachatium in Degradability of Dry Matter and NDF from Alfalfa

摘要：

　　We evaluated in situ a xylanase enzyme site (Fibrozyme,Alltech.Inc.)consisting of fermentation extracts and Aspergillu.s niger Trichoderma longibrachatium at different ruminal incubation periods (48,24,12,8,6,4 and 2 h )alfalfa hay.The variables were: DMD and NDFD and nonlinear parameters.T2 (adding enzyme)was higher (P<0.05 )in DMD and NDFD per period and completely,obtaining an effective degradability and passage rate higher (P<0.01 )than Tl.The addition of the xylanase enzyme rumen accelerated in the DMD in a shorter time (6-18 h)and NDFD (2-12 h).We conclude that adding the xylanase enzyme improves in less time degradability of DM and NDF,expecting increased feed intake and animal production.
