Proximate analysis and lipidic composition of lamb meat from Northeastern Brazil

The objective of this study was to evaluate the proximate and lipidic compositon of lamb meat from tropical sheep reared in Northeastern Brazil. Twenty-one rams, ten ½ Somalis Brasileira ½ ´ Crioula (SB-C) and 11 ½ Santa Inês ´ ½ Crioula (SI-C) were used. Two feeding regimes were utilized during weaning: grass hay (Cynodon dactylon) + leucena hay (Leucaena leucocephala) ad libitum (D1) and grass háy + leucena hay + 20% crude protein concentrate ad libitum (D2). It was not observed effect of crossbreed or feeding regime on proximate and lipidic composition of the meat. Moisture, protein, ash and fat values varied from 76.12 to 76.19%, 19.19 to 19.46%, 1.08 to 1.10% and 2.01 to 2.39%, respectively. Cholesterol content ranged from 54.43 to 60.05mg/100g of meat. The more abundant fatty acids in lamb fat were oleic, palmitic and stearic. Based on these results, it can be concluded that lamb meat from Notheastern Brazil has proximal and lipidic compositions similar to that animals from temperate regions of the World.
