Title: Studying the Growth, Carcass Traits and Tissue Distribution of Awassi and Hamdani Lambs Author: Rabee A. Kanyaw Abstract: ... The present work was carried out at the Animal Farm, Collage of Agriculture, University of Salahaddin, where 10 weaned lambs (4-5 months old) from each of Hamdani and Awassi, and averaged 22.0± 0.25 and 23.1± 0.34kg in weight, respectively were divided equally and randomly allocated to two slaughter groups (30 and 40kg).Each group of lambs was kept in a separate pen and fed a concentrate diet at libitum containing 16.2% crude protein and 2637 k cal. Upon reaching the prescribed weight, each lamb was slaughtered and their carcass was evaluated. Results revealed that Hamdani lambs surpassed significantly Awassi lambs in growth rate (0.348 vs. 0.307 Kg/day), dressing percentage (47.97 vs. 46.59%) and percent of fat tail (15.20 vs. 12.15%). In contrast, it appears that Awassi lambs had thicker fat thickness, and their carcasses contain higher proportion of lean (+ 6.11%) and fat (+ 9.13%) and lower proportion of bone (-18.37%) as compared to Hamdani lambs. Also , as the weight at slaughter increased, there is a significant ( p< 0.05) decrease in average daily gain, an increase in rib eye area , fat thickness , lean and fat content and lower proportion of bone. The percent contribution of carcass, noncarcass and fat tail to the total body fat was 51.72, 2.63 and 45.63%, respectively. Keywords: Growth, Carcass traits, Awassi, Hamdani, Lambs Show More |
