摘要
为了研究缓释包膜半胱胺对生长肥育猪生长性能和胴体品质的影响,选择"杜×大×长"三元杂交猪120头,随机分为3组进行对比试验,考察其生产性能、血液理化指标和屠宰性能指标。结果表明:试验组生长期、肥育期及全期平均日增重分别提高了7.34%、5.09%和6.32%;料重比分别降低了4.93%、3.19%和4.40%;平均日采食量分别提高了2.20%、1.61%和1.90%,但差异不显著。试验组的臀腿比例、眼肌面积和瘦肉率分别提高了9.25%、11.69%和6.27%;背膘厚降低了13.74%。试验组血清中GH、T3的含量分别提高了18.68%、20.63%,而对INS和T4无显著影响。表明日粮中添加缓释包膜半胱胺后,可能通过提高血清中GH、T3等激素的水平,改善生长肥育猪的生长性能和胴体品质。
In order to study slow-release coated cysteamine on growth performance of growing-finishing pigs and carcass quality, select ＂Du Chang Da＂ 120 crossbred pigs were randomly divided into three groups comparison test, examine its performance, blood physicochemical slaughter performance indicators and targets. The results show that： the experimental group growing season, full of fattening period and average daily gain were increased by 7.34%, 5.09% and 6.32%; feed conversion ratio were decreased by 4.93%, 3.19% and 4.40%; average daily feed intake were improved 2.20%, 1.61% and 1.90%, but the difference was not significant. Hip and leg percentage of the test group, loin eye area and lean meat rate increased by 9.25%, 11.69% and 6.27%; backfat thickness decreased 13.74%. Test group serum GH, T3 levels were increased by 18.68%, 20.63%, while no significant effect on the INS and T4. It showed that diets after slow-release coated cysteamine, may by increasing the level of serum GH, T3 and other hormones, improve growth performance and carcass quality of growing-finishing pigs.
