Abstract

The study aimed to investigate the effect of feeding corn oil as a rich source of linoleic fatty acid on productive performance, yolk fatty acid pattern, hatchability, and progeny growth of Hager 2 Saudi local strains. This study used 140 layers and 20 males at 31 week of age for 12 weeks experimental period. The hens were allocated into four treatments. The treated groups were fed four isocaloric corn-soy basal diets supplemented with 3% palm oil (T1, control), 2% palm +1% corn oil (T2), 1% palm+2% corn oil (T3) or 3% corn oil (T4). The main results indicated to insignificant increase in egg production % due to adding different levels of corn oil into diets while average egg weight was not affected by treatments. Daily feed intake slightly increased due to feeding dietary corn oil and feed efficiency ratios were similar. Egg yolk % increased significantly and yellowish yolk color was less due to adding 3% corn oil into diet. Both of egg albumen % and eggshell % was not affected by treatments. Plasma total cholesterol was reduced by feeding dietary corn oil which did not affect plasma triglycerides. Egg yolk cholesterol and triglycerides decreased significantly due to adding 3% corn oil only into laying hen diet. There were increments in total saturated fatty acids (SFA) ratio inherent with reduction in monounsaturated fatty acids (MUFA). Polyunsaturated fatty acid (PUFA) increased obviously due to treatments. Hatchability of chicks fed 3% corn oil diet was lower than other treated groups while fertility was not affected. Day-old progeny weights were significantly similar and parallel to the average egg weights. It can be concluded that, enriched high linoleic fatty acid into diets can increase average egg weights without any effect on reproductive aspects, fertility, hatchability, or weights of hatched chicks.
