Abstract: The objective of the present study was to evaluate the effects of sex and breed, on the slaughtering performance, carcass yield and cutting process in rabbits. Eighteen female and male rabbits of the Chinchilla and California breeds were used, animals were sacrificed according to the Official Mexican Norm. No significant differences between breeds and gender for all the variables were observed, except for ham roundness; California does showed the highest value, being significantly different from the males for both breeds. At 70 days, California rabbits showed a greater body development compared with the Chinchilla breed. Also, no significant differences were found between breeds for the primary cuts; although there was a numeric difference between Chinchilla and California rabbits regarding loin cut (291 vs. 273 g, respectively). The carcass yield obtained in this study was 58.51%, the greatest yield was observed in California does. Positive correlations were found between average daily gain and live weight (r= .89); skin weight and hot carcass weight (r=0.90), and live weight with both, skin weight (r= 90) and hot carcass weight (r=0.91).
