【摘要】 以每千克含０（对照组），４０ｇ（Ⅰ组），８０ｇ（Ⅱ组）ＬＦＡ_３日粮饲喂ＡＡ肉用公鸡４周，检测鸡肉品质。结果表明：与对照组比较，体增重和采食量Ⅰ组分别上升１２％和１３％，而Ⅱ组则下降１０％和７％；但Ⅰ组和Ⅱ组的绝对和相对腹脂重约分别下降３８％和４３％；Ⅱ组鸡肉脂肪含量下降２１．３％，且蛋白质含量上升３％。提示，ＬＦＡ_３能提高鸡肉的品质。ＬＦＡ_３的这种作用可能与日粮ＬＦＡ_３影响肉鸡体内的脂质代谢有关。更多还原

【Abstract】 After AA male broilers had been fed with diets containign 0（Control group）, 40（GroupⅠ） and 80（Group Ⅱ） g LFA₃/kg diet for 4 weeks the quality of broiler meat was deter-mined.The results showed that as compared with the COntrol group, the body weight gainand feed intake in GroupⅠincreased by 12%and 13%,but those in Group Ⅱ decreased by10%and 7%.However,the absolute and relative abdominal fat weight in GroupⅠ andGroup Ⅱ decreased by 38%and 43%,And the fat content of the meat in Group Ⅱ decreasedby 22%,but the protein content increased by 3%. Those results suggested that the quality ofmeat could been enhanced by LFA₃ and it was concluded that dietary LFA₃ may be used as aregulator of lipid metabollsm in broiler.更多还原
