| Abstract |
Slaughtering and dissection data on 25 male Sinai Gabali rabbits serially slaughtered (at 4,6,8, 12 and 14 weeks of age) were used to characterize allometric growth pattems, composition and weight-distribution of empty body and carcass. A similar number of New Zealand White (NZW) rabbits were used as a reference breed.
Growth of body relative to empty body weight (EBW), side entire Joints relative to Jointed side weight (JSW) and side major tissues relative to dissected side weight (DSW) were examined. The individual logarithmic regression slopes (growth coefficients) for Gabali and NZWrabbits were homogeneous for all body and carcass components and, thus, the common regression was used to represent the growth coefficient (b) for each component. Relative to EBW, the head, blood, feet, heart, lungs-plus-trachea, liver, alimentary tract, spleen and kidneys were early maturing (b<1), while, the pelt, abdominal fat and carcass were late maturing (b>1). As DSW increased the proportion of total side subcutaneous fat and total side intermuscular fat increased, that of total side bone and muscle to bone ratio decreased, while that of total side muscle remained almost without change (b=1).
Relative to JSW, the fore limb was early maturing, while the other three joints (hind limb, loin and thoracic cage) followed an average pattern of growth (b=1).
At constant EBW, the Gabali rabbits had significantly (P
