English Abstract

To evaluate the effect of breed and zeranol implantation on fatty acid composition of meat, ten intact weaned lambs from each Awassi and Karadi were divided equally into subgroups; the first as a control and the second was implanted with 12mg zeranol, fed a concentrate diet and slaughtered after 70 days of fattening.

After chilling, homogenous samples of meat from L.Dorsi muscle was blended for analysis of fatty acid composition.

Breed comparison indicated that C:18 is significantly higher and C16:1 is significantly lower in Karadi than Awassi lambs, Total fatty acid were higher (p> 0.05) in lambs implanted with zeranol as compared to intact lambs.

Also, a decrease (p< 0.05) in α-linolenic acid was observed in zeranol implanted lambs compared to control lambs.

Neither n-6: n-3 ratio nor PUFA to SFA was modified by implantation with zeranol.
