| Abstract: | 【Objective】In order to validate the effect of cellulose complex enzyme on beef cattle feeding.【Method】40 hybrid bulls from Simmental cattle aged 2 to 2.5 years in clinical healthy were selected according the same or similar age,weight and divided into the control and treatment groups,each group had 20 cattle.The experimental group was fed with silage maize straw processed by 0.1% cellulose complex enzyme preparation.The control group was fed with silage maize straw without any processing.The experimental time was 80 days.【Results】The body weight in treatment group increased 119.3 kg/cattle,and that in the control group increased 101.8 kg/cattle.On the body weight and average daily feed intake,the cattle from the treatment group increased 17.32% and 9%~10% than that from the control group(P<0.05).The feed cost of per kilogram weight gain reduced 11.04%.【 Conclusion】Cellulose composite enzyme preparation had significant effect on weight gain for fatten cattle. |
