Evening primrose oil and hemp seed oil as an gamma-linolenic acid source for broiler;Influence of fatty acid composition of chicken skin, thigh and breast muscle

The objective of this study was to determine the effect of dietary oils on the levels of the gamma-linolenic acid in chicken meat lipids. Three hundred ten five, 1-d old, male, Ross strain, broiler chicks were fed for 35 d to compare diets containing evening primrose oil(EPO) and hemp seed oil(HO) to a control diet. Fatty acid composition of lipid from chicken skin, thigh and breast muscle were determined at the end of the trial. The level of gamma-linolenic acid of lipids from chicken meat fed diets containing EPO or HO was significantly higher than that of the control group(p<0.05). The level of gamma-linolenic acid of lipids from chicken skin was highest in the group, which had been fed the EPO 0.85%, followed in order by EPO 0.7%, 0.5%, EPO mixed oil, HO and HO mixed oil. There was a significant difference in the level of gamma-linolenic acid of chicken skin between the control and treatment groups(p<0.05). The level of gamma-linolenic acid of lipids from chicken thigh muscle was also similar to skin, and significantly higher than that of the control group(p<0.05). The level of gamma-linolenic acid of lipids from chicken breast muscle was highest in the group, which had been fed the EPO 0.5%, followed in order by EPO 0.7%, 0.85%, HO 0.5% and HO mixed oil. There was a significant difference in the level of gamma-linolenic acid of chicken breast muscle between the control and treatment groups(p<0.05).
