ABSTRACT
The influence of probiotics bacteria and fibrolytic enzyme as feed additives were studied on digestibility coefficients, feeding values, , feed intake, daily gain and economical efficiencies with using thirty male buffalo calves in fattening trial. Rumen and blood parameters were also studied. First group (10 animals) were received control ration which contains 60 % concentrate feed mixture (CFM), 30 % corn silage (CS) and 10 % alfalfa hay (AH). The 2nd and 3rd animal groups were fed control ration supplemented with 5 gm probiotics bacteria and 10 gm fibrolytic enzyme per head , respectively. The experiment lasted about 180 days. Animals fed rations B and C appeared improvement in daily live body weight (LBW) gain with rate of 8.43 % and 13.19%, respectively. Consequently, animals fed supplemented rations showed significant better feed utilization efficiency as kg DM, TDN or DCP per kg gain. The feed cost per kg weight gain recorded 28.874, 27.899 and 26.815 LE with animals fed ration A, B and C, respectively. So, the improvement of economical efficiencies were found and recorded 3.46 and 7.76 % with animals fed ration B and C , respectively. Using probiotics bacteria and fibrolytic enzyme in rations of fattening buffalo calves tended to improve nutrient digestibility coefficients, feeding values and increase LBW gain. Moreover, these feed additives appeared to decrease feed cost per kg weight gain and increase net revenue with higher economical efficiencies. Blood and ruminal parameters were not affected by feed additives and they were within the ranges without side effects.
