The effect of breed on fatty acid composition of subcutaneous adipose tissues in fat-tailed sheep under identical feeding conditions
A study was conducted to evaluate the fatty acid (FA) profile of subcutaneous adipose tissue and tailfat of two fat-tailed sheep breeds under identical feeding conditions. Twelve male lambs from two breeds, Sanjabi (n = 6), weighing 23.3 ± 0.48 kg, and Mehraban (n = 6), weighing 26.1 ± 2.14 kg, were used in this investigation. All animals were weighed and slaughtered at the end of a 90-day fattening period and FA composition of subcutaneous adipose tissue and tailfat was determined. Significant breed differences in total FA, total polyunsaturated fatty acid (PUFA) and n-6PUFA contents were observed in the subcutaneous adipose tissue, but not in the tailfat. Breed differences were observed in the conjugated linoleic acid (CLA) content of subcutaneous adipose tissue, with higher levels in Sanjabi than in Mehraban lambs. Linoleic and α-linolenic acid of subcutaneous adipose were significantly higher in the Sanjabi breed than in the Mehraban breed. Thus, adipose tissue from fat-tailed Sanjabi lamb has a higher proportion of health-promoting linoleic and α-linolenic acids, unsaturated fatty acids (UFA) and CLA, suggesting that the Sanjabi breed could be used for producing healthier lamb productsKeywords: Fatty acid profile, Iranian sheep breeds, Mehraban lamb, Sanjabi lam
