Application of total mixed ration technique in beef cattle fattening
摘要
Abstract
This study aimed to analyze the impact of total mixed ration and traditional separate ingredients on weight gain, perfonnance of meat production and economic of fattening in beef cattle. A total of 14 Simmental cattle of body weight (455±l0) kg and age-matched hybridization were randomly divided into the control group ( separate ingredients) and the tested group ( total mixed ration) for the 153 days'experiment by using completely random block design methods. Two group animals were kept under the same conditions of the daily gains,feeding and management conditions, but provided with different feeding methods. The results were followed : 1. The average daily gains of beef catde in the control group was ( 968. 2±86. 84) g and the tested grroup was ( 1078.5±40. 04) g, increased by 11. 4% with a significant difference (P<0. 05) . 2. The dresaing percentage, net beef percentage, meat percentage of carcass, meat-bone ratio, eye muscle area, water loss rate and percentage of different grades of meat , there were differences in both groups but did not reach a significant level ( P>0. 05 ) .3. The profit of each beef cattle in the tested group increased 243. 4 yuan more than that in the control group in 153 days' feeding. All these showed that application and popularization of total mixed ration feeding techniques, instead of the traditional separate feeding of roughage and concentrate, would have a better fattening effect.关键词
