选用大小一致的吉富罗非鱼鱼种315尾,随机分成3组,每组3个重复,每个重复35尾,分别饲喂3.7%、7.7%和16.6%的低、中、高脂肪水平的等氮饲料,探讨不同脂肪含量饲料对吉富罗非鱼鱼种生长、肝体指数、脂肪沉积、脂蛋白脂酶活性及其基因表达的影响,试验周期90天。结果表明,脂蛋白脂 A total of 315 Jugular tilapia species of the same size were selected and randomly divided into 3 groups of 3 replicates each with 35 repeats fed 3.7, 7.7 and 16.6% respectively of low, medium and high fat The effects of different diets on the growth, hepatic body index, fat deposition, lipoprotein lipase activity and gene expression in fingerlings of GIFT tilapia were studied. The experiment period was 90 days. The results show that lipoprotein lipids
