In this study, data of body weight at slaughter （SW; n = 465）, hot carcass weight （HCW; n = 465）, cold carcass weight （CCW; n = 401）, carcass lean weight （CLW; n = 314）, carcass bone weight （CBW; n = 401）, c...In this study, data of body weight at slaughter （SW; n = 465）, hot carcass weight （HCW; n = 465）, cold carcass weight （CCW; n = 401）, carcass lean weight （CLW; n = 314）, carcass bone weight （CBW; n = 401）, carcass total fat weight （CTFW; n = 314） and fat-tail weight （FTW; n = 401） in Lori-Bakhtiari sheep were measured to determine their possible use in breeding programmers aimed at improving ability to carcass quality in this breed. Lambs were slaughtered at 195 ＋ 27 days of age. The method of slaughtering and cultting was Iranian cutting approach. SAS procedures were used for the statistical analysis. Means and their respective standard deviations for SW, HCW, CCW, CLW, CBW, CTFW and FTW were 45.41 ± 6.86, 22.81 ± 4.32, 22.53 ± 4.18, 11.14 ± 1.71, 3.47 ± 0.43, 7.19 ± 2.42 and 3.65 ± 1.37 kg, respectively. The coefficients of variation for CTFW and FTW were 33.62 percent and 38.01 percent, respectively. Environmental effects of kind of rearing after weaning and type of birth on HCW, CCW, CLW, CTFW and FTW traits were significant. Consequently, considerable variation exists for carcass composition traits, especially for carcass fat and fat-tail.展开更多
