Abstract: In order to promote the application of crossbreeding technology and improve the production efficiency of Longlin goats in Guangxi,this study focused on Nubia goats,Longlin goats and Nulong hybrid F1 generations (Nubia goats♂×Longlin goats♀),all the goats were raised and managed at the same level.Three groups of 205 goats were selected to measure the growth performance and body size of goats at 1,3 and 6 months old.6 parents and F1 hybrids of 6 months old goats were slaughtered and their longissimus dorsi muscles were taken for meat quality analysis.The results showed that there was no significant difference between the lamb rate and lamb survival rate of the F1 generation of Nulong hybrid and the parent generation (P>0.05).The birth weight,body size index of different month ages were extremely significantly different from that of the parent generation (P<0.01).The weight,weight of carcass,net meat weight,slaughter rate and net meat rate of Nulong hybrid F1 were significantly improved compared with Longlin goats (P<0.05).The muscle crude protein content,muscle fat content,essential amino acids,flavor amino acids,free fatty acids of Nulong hybrid F1 generation all had different degrees of improvement when compared to parents.Therefore,Nubia goats had good comprehensive performance in improving body shape,growth rate and meat quality of Longlin goats.

Key words: Longlin goats; Nubia goats; production performance; meat quality
