Abstract :
Because of high cost of refined vegetable oil as
feed energy source for poultry and successful results with
dietary supplementation of some refining oil wastes for
broilers, finding of energy feeds alternatives for poultry
nutrition seems to be essential. The current experiment was
conducted to compare the growth performance of broilers
fed control diets contained refined sunflower oil as energy
source with other two groups fed diets contained frying oil or
acidulated soap stock as energy sources. They fed on isocaloric
starter, grower, and finisher diets contained 2.5%,
3%, and 3.5% of these energy sources at 0-14 days, 14-28,
and 28-42 day of age, respectively. No significant difference
were obtained for different parameters of growth
performance, carcass parts and traits of groups fed diets
contained refined sunflower oil or frying oil or acidulated
soap stock of sunflower oil waste. An increased plasma HDL
and reduced plasma VLDL for groups fed diets contained
frying oil or acidulated soap stock. A negative relationship
between plasma cholesterol and triglyceride values was
observed in the groups fed diets contained frying oil or
acidulated soap stock and the control birds fed diets
contained refined sunflower oil. Furthermore, plasma
malondialdehyde concentrations increased in the birds fed
diets contained frying oil and those fed diets contained
acidulated soap stock compared to the control group. It was
concluded that normal frying sunflower oils and acidulated
soap stock of sunflower oils can be used as economic
alternative feed oils for quality refined sunflower oils as
energy sources in the broiler`s diets.
