| Summary: | This study was carried out to investigate the effects of different
energy sources used in broiler diets on occurence of fatty liver
syndrome. Four hundred male and 400 femal dayold Arbro 7 were randomly
distributed by sex into sixteen pens with each pen containing 50
chicks.<p>
In eight experimental rations, 1. Corn (M); 2. Sunflower oil (2.5 %)
(AY<sub>1</sub>); 3. Sunflower oil (5 %) (AY<sub>2</sub>); 4. Fish oil (2.5 %) (BY<sub>1</sub>); 5. Fish
oil (5 %) BY<sub>2</sub>); 6. Animal fat (2.5%) (HY<sub>1</sub>); 7. Animal fat (5%) (HY<sub>2</sub>);
8. Wheat + Sunflower oil (3 %) (BAY) were used as supplemental or
based energy sources. Each ration was fed to one male and one female
•group. Thus, sixteen groups were set up and experiment was ended at
the 56th day.<p>
At the 56th day of the experiment, the highest liver weights and liver
fat percentages of the male chickens were found in BY<sub>1</sub> and BY<sub>2</sub> fed fish oil. On the other hand, the highest liver weight was found in BY<sub>2</sub> and the
highest percentage of liver fat was observed in BY<sub>1</sub> in the females.<p>
At the end of the experiment, in macroscopic investigation of livers
of the male and female chickens fed fish oil were yellowish pale, swollen
and crispy. In microscobic investigation of the livers in the same groups,
the excessive amounts of lipid infiltrations were seen in the cytoplasma
of paranchymal cells. Simiral observation was found in the livers of female
chickens fed corn. There were the excessive amounts of lipid infiltrations
in M and BAY in males and in HY<sub>1</sub> and BAY females, but the lipid level
was less than the above groups. By contrast, the lesser amounts of lipid
infiltrations were observed in the liver paranchymal cells of the chickens
fed the rations supplemented vegetable or animal fat.<p>
As a result, because of the best effect on the reduction of fat level
obtained with supplementing various levels of sunflower oil, it is sug•
gestecl that the vegetable oil be used in broiler rations as an energy
substitute of some part of corn. On the contrary, fish oil used in broileı
rations increasecl liver fat accumulation and caused fishy smell in meat. |
