摘      要：[Objective]The aim was to evaluate heterosis of hybridization groups of New Zealand White rabbits and Fujian Yellow rabbits. [Method] Totaling 80 rabbits,including New Zealand White rabbits,Fujian Yellow rabbits,and direct-cross and reciprocal cross rabbits were measured in slaughter performance and meat quality. [Result] Live-weight,evisceration weight and semi-evisceration weight of rabbits in four groups were 1 817. 20 -2 308. 60,914. 10 -1 231. 50 and 985. 99 -1 315. 20 g,respectively. For slaughter performance,FY × NZ was the highest among male rabbits and NZ was the highest among female rabbits. In addition,shear forces of crureus and longissimusdorsi for rabbits in four groups were 25. 11 -40. 44 and 18. 02 -26. 44 N,respectively,among which male NZ was the lowest in shear force of crureus and female NZ was the lowest of longissimusdorsi. Water-loss rates of crureus and longissimusdorsi were 33. 43% -41. 52% and 31. 79% -39. 01%,among which male NZ proved the lowest in water-loss of crureus and male FY achieved the lowest level for the rate of longissimusdorsi. [Conclusion]Hybrid groups showed some heteroses in slaughter performance and meat quality.
