The results showed that hybridization of Nubian black goat and Hainan black goat significantly improved the production performance and slaughter performance of hybrid offsprings (P>0.05). The meat quality of F1 hybrid black goat had no significant difference with that of Hainan black goat except for the hardness and elasticity (P<0.05). Therefore, the crossbred progenies of Nubian black goat and Hainan black goat have advantages in meat yield and meat performance, and the main meat quality indexes are not significantly different, which meets the market requirements for high-yield and high-quality hybrid combinations, and can be used for cross promotion.展开更多

[Method]Four 6-month-old Hainan black goats and Hainan black goat × Nubian black goat F1 were slaughtered respectively,and the contents of crude protein,total fat,moisture,amino acids,mineral elements( Se,Zn and Mn) and fatty acid were determined. [Result]There was no significant difference in total fat,crude fat and moisture content in muscle of Hainan black goat × Nubian black goat F1 and Hainan black goat( P > 0. 05). The Fe content in the muscle of Hainan black goat × Nubian black goat F1 was significantly higher than that in Hainan black goat( P < 0. 05). There was no significant difference in EAA,NEAA,TAA and FAA between Hainan black goat × Nubian black goat F1 and Hainan black goat( P > 0. 05). The C17∶ 0 methyl heptadecanoate content in the muscle of Hainan black goat × Nubian black goat F1 was extremely lower than that in Hainan black goat( P < 0. 01),but the saturated fatty acid content and total unsaturated fatty acid content in the muscle of Hainan black goat × Nubian black goat F1 was lower than that in Hainan black goat( P > 0. 05). [Conclusion]The meat quality characteristics of Hainan black goat × Nubian black goat F1 had little difference with its female parent,and the goal of breeding had been basically achieved.展开更多
