不同开填体重朗德鹅产肝性能的比较试验

对不同开填体重的朗德鹅产肝性能进行了比较分析。结果发现:4.2 kg体重组的平均肝重最大,为827.50 g,极显著高于3.8 kg、3.0 kg体重组(P<0.01);4.7 kg体重组的肝重明显低于4.2 kg体重组,但没有达到显著水平(P=0.20);相关分析发现开填体重与肝重之间呈极显著的正相关;通过建立回归曲线得出国内朗德鹅12周龄的最佳开填体重为4.5 kg。对肥肝重与腹脂重、皮脂厚等指标进行了相关性分析,发现肝重与腹脂重呈正相关且达到显著水平(P<0.05),说明脂肪组织的脂肪沉积与肝脏的脂肪沉积有密切的关系。

The comparative assay on production performance of foie gras produced by Landes goose with different initial body weight

The comparative assay on production performance of foie gras produced by Lande goose with different initial body weight was carried out. The results showed that there was a significant different(P<0.01) production performance among the groups with initial body weight of 4.2 kg,3.8 kg and 3.0 kg respectively;and the mean weight of liver was 827.50 g in the group of 4.2 kg.The mean weight of liver in the group with initial body weight of 4.7 kg was lower than that in the group of 4.2 kg,but there was no significant difference(P=0.20).The regression analysis showed a positive relationship(P<0.01) between weight of liver and initial body weight,and the regression function showed that the optimizest initial body weight of Landes goose was 4.7 kg.This paper also explored the relationship among foie gras production performance,weight of abdomen fat tissue and thick ness of sebum.The results showed a postitive relationship(P<0.05) between the former two,which suggested there existed a close relationship between fat tissue and liver in fat sediment.
