A trial was carried out to evaluate the effect of rabbit genotype on productive performance, data of slaughter and meat quality. A total of 170 growing rabbits of three different genotypes: commercial hybrids (CH) and rabbits obtained crossing hybrid does with males of New Zealand White (NZW Hybrid=NZWH) and of Burgundy Fawn (BF Hybrid=BFH). Individual live weight and feed consumption were recorded weekly and a sample of 81 days old rabbits (12 CH, 12NZWH, 12 BFH) were slaughtered. Slaughter live weights of BFH and NZWH resulted higher than CH ones. No differences resulted in the feed consumption. Commercial carcass rates were higher in BFH and NZWH than in CH mainly due to the lower skin percentage of the BFH and NZWH in respect to the CH one. In the CH reference carcass rates and loin rates were higher than the other two hybrids. About physical characteristics of meat the CH Biceps femoris resulted in higher value of Vhroma and of water holding capacity than the other groups.

Abstract
A trial was carried out to evaluate the effect of rabbit genotype on productive performance, data of slaughter and meat quality. A total of 170 growing rabbits of three different genotypes: commercial hybrids (CH) and rabbits obtained crossing hybrid does with males of New Zealand White (NZW Hybrid=NZWH) and of Burgundy Fawn (BF Hybrid=BFH). Individual live weight and feed consumption were recorded weekly and a sample of 81 days old rabbits (12 CH, 12NZWH, 12 BFH) were slaughtered. Slaughter live weights of BFH and NZWH resulted higher than CH ones. No differences resulted in the feed consumption. Commercial carcass rates were higher in BFH and NZWH than in CH mainly due to the lower skin percentage of the BFH and NZWH in respect to the CH one. In the CH reference carcass rates and loin rates were higher than the other two hybrids. About physical characteristics of meat the CH Biceps femoris resulted in higher value of Vhroma and of water holding capacity than the other groups.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
