【 摘 要 】

This research was conducted to examine the commercial cuts of thin tailed lambs and sheep fed complete feed. This study used 6 male thin tailed sheep aged ±11 months with average body weight of 23,01 ± 1,91 kg (CV 8,31%) and 6 male thin tailed lambs aged ±4 months with average body weight of 15,41 ± 2,11 kg (CV 13,72%). They were fed a complete feed as much as 3.5% from body weight. Fed contained 12% crude protein (CP) and 55% total digestible nutrients (TDN) and was given ad libitum. The animals were raised for 12 weeks and slaughtered being carcass. Commercial cuts were obtained from a half right body part of each sheep carcass and divided into eight commercial cuts, i.e., neck, shoulder, fore shank, breast, flank, rack, loin and leg. The collected data was analysed using t- test in 5% level. The results showed that slaughter weight, carcass weight and half carcass weight were significantly different (P0.05). All of the weight commercial cuts of thin tailed lambs and sheep were significantly different (P0.05). The percentage of neck and leg were significantly different (P
