摘    要:研究在育肥牛精料中添加0.3mg/kg有机硒,结果表明:平均日增重提高8.7%(P〉0.05),干物质采食量减少12.4%(P〉0.05),饲料干物质报酬提高7.7%(P〉0.05),蛋白质效率提高3.1%(P〉0.05);肉牛屠宰率、胴体产肉率、净肉率分别提高4.1%、1.26%、5.4%(P〉0.05);肉中CP、Ca、P、Fe、Zn、Mg、Na、K含量分别提高7.2%(P〉0.05)、12.5%(P〈0.05)、20.6%(P〈0.05)、23.08%(P〈0.05)、11.38%(P〉0.05)、21.11%(P〈0.05)、39.11%(P〈0.01)、8.6%(P〉0.05),硒的含量提高72.8%(P〈0.01),氨基酸总量、必需氨基酸总量、鲜味氨基酸总量分别提高17.7%(P〈0.05)、16.6%(P〈0.05)、19.7%(P〈0.05)。

Abstract:An experiment was carried out to study on feeding with the concentrate added with Organic Selenium(0.3mg/kg).The results showed that the test group ADG raise 8.7%(P>0.05),the ADMI declined 12.4%(P>0.05),the DM efficiency of trial group was 8.7% higher than that of control group(P>0.05),the PER was 3.1% higher than that of control group,the DR,NMR,MRC of finishing cattle in experiment group respectively enhanced 4.1%,5.4%,1.26% in compared with that of control group(P>0.05),the content of CP,Ca,P,Fe,Zn,Mg,Na...
Keywords:finishing cattle  organic selenium  production performance  carcass performance  meat quality
