大豆레시친의 給與가 Brolier의 肝臟 脂質代謝에 미치는 영향 = Effect of Dietary Soybean Lecithin Lipid Metabolism in Liver of Broiler

다국어 초록 (Multilingual Abstract)

In order to study the effects of dietary crude soybean lecithin and crude mutton fat an lipid merabolism in broiler liver, the content of triglycerides and the composition of fatty acids in liver tissues were determined at 4th and 8th weeks of feeding with formulated rations.
The levels of crude soybean lecithin and crude mutton fat added to the rations were 0% (control), 3% and 6% each, and the rations were formulated to make same proteins and similar calore/protein ratio in treatment.
The results obtained are summarized as follows:
1. There was no significant difference between tested group and control group in body weight gain, feed intake and feed conversion ratio.
2. Liver weight showed no prominent difference between tested groups and control, but fat contents in the liver were significantly decreased in lecithin groups, both in 3% and 6%.
3. In tested groups, both crude soybean lecithin and crude mutton fat groups, triglycerides were significantly decreased at 4 th week, but no significant changes are noted between tested groups and control group.
4. The cholesterol content in the broiler liver decreased significantly in crude soybean lecithin groups (3% and 6%) and 3% group of crude mutton fat at 4 th week, while it slightly increased at 8th week in most of tested goups, particularly, in 3% group of crude mutton fat the significancy of increase was prominent.
5. The main fatty acids compositions of total lipid in the liver were palmitic acid, stearic acid, oleic acid and linoleic acid in both tested and control groups, but the linoleic acid content was much higher in crude soybean lecithin groups than in the control and crude mutton fat groups, at both 4 th week and 8 th week.
