Effect of Aspergillus niger and Trichoderma Iongibrachatium in Degradability of Energy and Crude Protein from Alfalfa

摘要：

　　We evaluated a xylanase enzyme site(Fibrozyme,Alltech,Inc.)consisting of fermentation extracts and Aspergillus niger Trichoderma longibrachatium at different ruminal incubation periods (48,24,12,8,6,4 and 2 h)alfalfa hay.The variables were: DNEg and CPR and nonlinear parameters.T2 (addition of enzyme)was higher in Deng from 7 to 18 h,more efficient: form 48.2%-37.72% in total and 37.88% (P<0.05).No differences (P<0.05 )in the mean total for CPR (crude protein residues).The CPR evident(P<0.01)higher effective degradability for 20.0606a vs.16.3083b T2 = (T1)and degradability rate 9.40a h-l (T2)and 0.16 (T1).We conclude that adding the xylanase enzyme production improvement expectations due to its effect reflected in increased availability of net energy.
