本研究以雌性化雏鸡为对象，通过三个试验研究了等能日粮中添加和不添加鱼粉及其组分对肝脏脂质沉积的影响。在饲喂实验饲料之前，鸡禁食48小时，并在实验期间注射雌二醇三次。4天后，测定肝脏脂质含量。在第一个实验中，每单位肝脏和每100克体重沉积的肝脏脂质的量显着低于鸡喂食10%的鱼粉和乙醇提取物的鱼粉相当于10%比鸡喂食未补充玉米-大豆饮食。在第二个实验中，用10%鱼粉观察到每100 g体重沉积的肝脂质显著减少，但用相当于10或20%的鱼粉乙醇提取物和相当于20%的乙醇提取物的灰分仅在数值上减少。在第三个实验中观察到一个非常显着的减少肝脏脂质沉积的鸟类refered饮食含有鱼粉，苜蓿，酵母，但喂养这之前的饥饿再喂养期没有影响肝脏脂质。这些结果表明，鱼粉具有降低肝脏脂质的活性，并建议该活性可以用乙醇提取。
Three experiments were conducted for the purpose of determining the effect of feeding isoenergetic diets with and without fish meal or its fractions on hepatic lipid deposition in estrogenized chicks. The chicks were fasted for 48 hr before being fed the experimental diets and were injected with estradiol three times during the experiment. After 4 days, hepatic lipid content was determined. In the first experiment, the quantity of hepatic lipid deposited per unit of liver and per 100 g body weight was significantly less for chicks fed 10% fish meal and an ethanol extract of fish meal equivalent to 10% than for chicks fed an unsupplemented corn-soy diet. In a second experiment a significant reduction in hepatic lipids deposited per 100 g body weight was observed with 10% fish meal but only a numerical reduction with ethanol extracts of fish meal equivalent to 10 or 20% and the ash of ethanol extract equivalent to 20%. In a third experiment a highly significant reduction in hepatic lipid deposition was observed in birds refed a diet containing fish meal, alfalfa, and torula yeast but feeding this before the starvation-refeeding period did not affect liver lipids. These results show that fish meal contains hepatic lipid lowering activity in refed estrogenized chicks and suggest that the activity may be extracted with ethanol.
