Carcass and Meat Characteristics of Traditionally Managed Nigerian Yankasa and West African Dwarf Breeds of Sheep

摘要

The carcass characteristics of Nigerian West African dwarf (WAD) and Yankasa breeds of sheep managed under traditional systems were compared. These two breeds were represented by six animals each with an average body weight of 18.97±0.36kg. The animals were slaughtered and carcass weight, yields, composition and sensory properties scores were recorded. Results indicated that breed primarily differed in carcass traits and retail cuts. Yankasa breed had a significant higher (P0.05) ranked the same across the two breed. Weights of the head and empty gut were significantly (P0.05) lower in WAD sheep compared with Yankasa sheep. The crude protein and fat contents of meat from loins were higher (P0.05) in WAD sheep. Following assessment, eating quality traits varied across breeds, panellist-rated flavour, juiciness and overall acceptability higher (P0.05) in WAD meat. In conclusion, Yankasa sheep have a better carcass and dressing percentage but the overall sensory is better for the West African Dwarf. These may be due to the higher fat and protein contents resulted in more flavour, tender and juicy meat.
