| Abstract | ||
| The aim of this experiment is to compare two feeding systems based on the productive performance and some carcass characteristics of fattened male lambs: feeding once and feeding twice daily. We conducted this experiment by fattening two groups of Awassi male lambs, totalling twenty weaned male lambs ranging in age from 4 to 6 months. The average weight of all lamb[23.28 ±1.27]. They were distributed equally, according to weight, into two groups, so that each group consisted of ten lambs. This experiment continued for eighty days. Following a 12-hour food withholding period, we slaughtered six lambs from each group, taking their total weight prior to slaughter. Then the lambs were slaughtered, and the carcass measurements were taken. The results did not show any significant differences for most measurements, such as final weight, weight gain, feed conversion efficiency, feed intake, carcass weight, dressing percentage, and carcass residues from the head, feet, and skin. There were also no big differences in the viscera of the carcass, like the lungs, heart, liver, spleen, kidneys, intestines, the weight of the full and empty rumen, or the weights of different fats, like buttocks, abdomen, kidney, and heart fat. There were also no big differences in the area of the eye muscle or the thickness of the subcutaneous fat, or in the major and minor cuts, except for the weight of the breast. Moreover, the proportions of muscle, fat, and bone remained consistent. The net second transaction exhibits an arithmetic advantage. | ||
