Abstract
This study was conducted with the objective to evaluate carcass weight, meat yield and primal meat cuts of beef from Arado, Boran, Barka, Raya and nondescript cattle breeds slaughtered at export abattoirs in Ethiopia. Data was collected from Abergelle and Melgawendo export abattoirs in 2011. The result of the study revealed that the average live weight, warm carcass weight, cold carcass weight and warm dressing percentage of cattle slaughtered at the abattoirs studied were 241.41±0.37 kg, 106.93±0.21 kg, 101.19±0.18 kg and 44.21±0.05%, respectively. Live weight, carcass weight and dressing percentage were differ (P < 0.001) between abattoirs, seasons and breeds of cattle slaughtered. Average meat yield and yield percentage of cattle slaughtered at Abergelle abattoir was 61.56±0.94 kg and 67.81±0.33%, respectively. Meat yield and weight of primal meat cuts were different (P < 0.001) between breeds of cattle. Yield percentage was significantly (p < 0.05) different between seasons. Retailed meat yield was significantly predicted (R2 = 88.1%) from slaughter weights, Topside (R2 = 77.86), Silverside (75.64), Knuckle (R2 = 70.13), Striploin (R2 = 70.73), Tenderloin (R2 = 61.33), Shank (R2 = 64.55) and Rumpcap (R2 = 64.48). From the study it was concluded that Boran cattle was better in dressing percentage compared to most cattle breeds in Africa while the dressing percentage and meat yield of Arado, Barka and Raya breeds were less than the percent and yield reported for other zebu cattle in Africa. A strategy should be devised to improve the carcass weight, dressing percentage and retail able meat yield from local cattle in Ethiopia.
Highlights
Ethiopia has 59.4 million cattle (CSA, 2017) and about 33 cattle breed (EBI, 2016)
The aim of this study was to evaluate carcass weight, meat yield and primal meat cuts of beef from Arado, Boran, Barka, Raya and nondescript cattle breeds slaughtered at export abattoirs in Ethiopia
Live weight of cattle slaughtered at Melgawendo abattoir (284.02±0.92) was significantly higher (p < 0.001) than cattle slaughtered at Abergelle abattoir (238.16±0.27)
Summary
Ethiopia has 59.4 million cattle (CSA, 2017) and about 33 cattle breed (EBI, 2016). The potential of these breeds for meat was not properly studied. Understanding the carcass traits and meat yield of a breed is a prerequisite to identify the potential of a breed for meat production. It is important to evaluate the amount of meat that can be marketed and available as a food for the consumers. Consumers place high emphasis on food quality, and their decision on purchasing a product is mainly based on color (Marenčić et al, 2012). The pH value has a significant impact on the color, shelf life, taste, microbiological stability, yield and texture of meat and meat products and is, important for meat quality evaluation (Feiner, 2006)
