Analysis of 6-Month-Old Lambs Meat Production Performance among Different Hybrid Combinations in Qilian Mountain Alpine Pastoral Areas
摘要
Abstract
In order to select an optimal hybrid combination and improve the growth and meat production performance of F1 generation lambs at 6-month-old age in Qilian mountain alpine pastoral areas,Texel, Poll-Dorset,Black Suffolk were used as male parent and Gansu Alpine Merino as female parent to conduct hybrid combination experiment ( F1 generation lambs of each combination were referred to TG, DG and BSG,respectively) in this study. The results showed that F1 generation lambs birth weight of each hybrid combination had no significant difference. The F1 generation rams weaning weight and average daily gain before weaning of TG,DG and BSG were extremely higher than Gansu Alpine Merino,and increased by 26 . 01%, 42 . 91%, 35 . 45% and 31 . 81%, 49 . 66%, 43 . 64%. The 6-month-old body weight before slaughter and carcass weight of TG,DG and BSG were higher than Gansu Alpine Merino,and increased by 26. 25%(P<0. 01),9. 89%(P<0. 05),26. 02%(P<0. 01) and 41. 18%(P<0. 01),21. 60%(P <0. 01), 37. 62% ( P < 0. 01 ). There was no significant difference in dressing percentage of each combination rams,while F1 generation ewes dressing percentage of TG,DG and BSG extremely higher than Gansu Alpine Merino. These results suggested that the growth and meat production performance of Gansu Alpine Merino could be improved by introducing foreign sheep, and TG was the optimal hybrid combination for manufacturing 6-month-old mutton in Qilian mountain alpine pastoral areas compared with other combinations.关键词
