This study was devised to observe the effect of diet supplemented with lard and chiken fat ,on rat.
The diet was prepared by adding 4, 8 and 209% of each fat respectively, but the level of protein was maintained equally.
Each diet was given to given to male rats weighing from 260 to 2708 for 8 weeks continuously, and the body weight, food efficiency ratio and the change of body composition of
a.
experimental animal were determined.
The results were obtained are as follows,
1. The body weight of 2090 lard diet group( 1) was lower than control group.
2. Without regard to the content of supplemented fat, the changes of liver weight were similar.
3. The amount of food in take was shown decreasing tendency according to increase of fat content in the diet in generally.
4. The amount of daily average energy intake was lower in 4g%, 20g% lard diet group and ~;. 4g9,1 or chiken fat diet group than control group.
5. The food and protein efficiency ratio of eash experimental diet group were no significant difference compared with control group.
6. The values of hemoglobin and hematocrit were not effected by feeding of the diet supplemented with lard and chicken fat.
7. The content of total cholesterol:
The content of total cholesterol in serum was increased generally during whole reeding period, while that of liver was decreased compared with control group.
8. The contents of serum total cholesterol, triglyceride and phospholipid of experimental group were increased compared with control group, while the content of total lipid in liver had a tendency to decrease.
From the above results, it was found that the utilization of supplemented lard and chiken fat in the body was good at concentration of-below gg while excessive amount of above 20gib decreased the utilization.
In addition, it was concluded that the content of total cholesterol and total li id in liver were not significantly changed when 48% fat was supplement to diet, while those of serum were increased by excessive intake of animal fat like lard or chiken fat.
