Abstract: 【Objective】 The aim of this study was to compare the slaughter performance and meat quality of Nu-Gui hybrid F1 generation goats (Nubian goats♂×Guizhou Black goats ♀) with purebred Guizhou Black goats,and explore the improvement effect of crossbreeding Nubian and Guizhou Black goats on the production performance of Guizhou Black goats.【Method】 Thirty male lambs of Nu-Gui hybrid F1 generation and Guizhou Black goats born in the same period were selected,respectively,the birth weight was recorded,and the body weight and body size were measured at 3,6,9,and 12 months of age.Seven Nu-Gui hybrid F1 generation and Guizhou Black goats at 14 months of age were randomly selected for slaughter,respectively,the slaughter performance was determined.Meanwhile,the meat quality traits and the contents of amino acids and fatty acids in longissimus dorsi muscle were determined.【Result】 ①The body weight of Nu-Gui hybrid F1 generation goats at 3,6,9,and 12 months of age were significantly higher than those of Guizhou Black goats (P<0.05),and all body size traits at 12 months of age were significantly higher than those of Guizhou Black goats (P<0.05).②The slaughter rate,pure meat percentage,carcass net meat rate and eye muscle area of Nu-Gui hybrid F1 generation goats were significantly higher than those of Guizhou Black goats (P<0.05).③The muscle shear force and dripping loss of Nu-Gui hybrid F1 generation goats were significantly lower than those of Guizhou Black goats (P<0.05),and the cooked meat percentage was significantly higher than that of Guizhou Black goats (P<0.05).④17 kinds of amino acids and 37 kinds of fatty acids were detected in longissimus dorsi muscle of Nu-Gui hybrid F1 generation goats,the contents of lysine,glutamic acid,aspartate,oleic acid,linoleic acid,gamma linolenic acid, and arachidonic acid were significantly higher than those of Guizhou Black goats (P<0.05),while the contents of arginine,palmitic acid, and stearic acid were significantly lower than those of Guizhou Black goats (P<0.05).There was no significant difference in the content of saturated fatty acids between two breeds (P>0.05),but the contents of monounsaturated fatty acids and polyunsaturated fatty acids of Nu-Gui hybrid F1 generation goats were significantly higher than those of Guizhou Black goats (P<0.05).【Conclusion】 The crossbreeding between Nubian and Guizhou Black goats could significantly improve the growth rate and meat production performance of F1 generation,and improve the muscle quality.
