摘要
本试验采用单因子设计方案,将450只70日龄同批孵化、体重相近、健康的朗德鹅随机分成3组,其中Ⅰ组为对照组,Ⅱ组和Ⅲ组分别为试验组。Ⅰ、Ⅱ、Ⅲ3组在超饲养饲粮基础上分别添加2%的鹅油、2%豆油和2%玉米油,研究不同脂肪源填饲3周后对朗德鹅肥肝的卵磷脂等含量的影响及其经济效益分析。试验结果:①填饲后,试验组和对照组肥肝中脑磷脂、卵磷脂、不饱和脂肪酸、蛋白质和脂肪含量与填饲前比较差异显著(P<0.05),试验组与对照组比较及组内差异均不显著(P>0.05)。②试验Ⅱ、Ⅲ组与对照Ⅰ组相比,每只鹅分别增收8.8元和7.71元。
Experimental design method of the single factor was adopted in this research. 450 ten-week Landes geese, which were raised well in the same batch with similar weight, were randomly divided into 3 groups. The first group was control group, others were testing group （each of them contained 150 geese with 3 repetitions）. In addition to overfeed, 2% of goose oil, 2% of bean oil and 2% of corn oil were added into the first, the second and the third group, respectively. The effect of different kinds of oil supply on lecithin in fatty liver was investigated after three weeks of overfeed and the economic returns was analyzed. The results showed that after overfeeding there was remarkable （p〈0.05） difference in contents of cephalin, lecithin, unsaturated fatty acid, protein and fat in liver compared with those pre-feeding geese. There was not remarkable （p〉0.05） difference between the control group and the test group, and the geese in each group. Compared with the first group, each goose in the second and the third earned 8.8 yuan and 7.71 yuan RMB, respectively.
