Twelve buffaloes, nine Friesian × Baladi and nine Friesian × (Friesian × Baladi) bulls were slaughtered over the live weight ranges 161-560 kg for buffaloes and 176-448 kg for cattle. Right sides of all carcasses were jointed and dissected and the increase in the weight of 'entire' and 'boneless' cuts and cut groups (i.e. pistol; BLRC) relative to the 'entire' and 'boneless' side weights, respectively, were examined using covariance analyses. Increasing distoproximal and dorsoventral growth gradients were found in both species. Most noticeably, the sticking was early developing in buffaloes and late developing in cattle, whereas the shortloin developed approximately at an average rate in buffaloes and at a lower rate in cattle. Statistically significant but relatively slight differences were recorded between buffaloes and cattle in the adjusted means of the 'entire' and 'boneless' hind shank, sirloin (favouring buffaloes) and brisket (favouring cattle). Buffaloes were superior to cattle in weight of pistol. At an equal side weight of 73 kg buffaloes had significantly higher weight of pistol (maximum difference = 1·4 kg). At a 115 kg side weight, the maximum difference in 'entire' and 'boneless' pistol reached 3·58 and 5·04 kg, respectively., (Copyright © 1982. Published by Elsevier Ltd.)

Six buffalo bulls and six buffalo cows were slaughtered between, respectively, 430-560 kg and 405-585 kg liveweight. Sex differences in fat partition and distribution were examined using one-way analyses of covariance on data converted to logarithms. Buffalo bulls and cows showed no significant differences in the partition of total body fat between the carcass and the offal or between the different components of the total carcass fat (subcutaneous, SCF; intermuscular, IMF; kidney and channel, KCF) and those of the total offal fat (caul; mesenteric; heart). In addition, no significant differences between bulls and cows were detected with respect to the partition of the entire side fat between its component depots (SCF; IMF; KCF) and the partition of the dissected side fat (DSF) between its elements (SCF; IMF). Bulls did not differ significantly from cows in the distribution of IMF between cuts. However, bulls had more of their total SCF in the buttock cuts (P < 0·05) and pistol (P < 0·001) and BLRC (P < 0·01) expensive cut groups, while cows had more weight of total SCF contained in the flank (P < 0·05) and the 7th-10th rib (P < 0·01). The weight of total DSF was greater (P < 0·05) in the buttocks of bulls and (P < 0·01) in the flanks of cows., (Copyright © 1982. Published by Elsevier Ltd.)

Carcasses from six buffalo bulls (slaughtered between 430 and 560 kg liveweight) and six buffalo cows (slaughtered between 405 and 583 kg liveweight) were dissected, the left sides by the anatomical approach, the right sides being jointed and the joints being dissected into fat, muscle, bone and other tissues. Weights of the anatomically dissected muscles and bones, and weights of muscle and bone dissected from each cut, were regressed on weight of the respective tissue in the side. The influence of the animals' sex on tissue distribution was investigated using a one-way analysis of covariance. Results were consistent with those reported on cattle in that (i) sex had no influence on the amount of total muscle occurring in the distal parts of limbs or surrounding the spinal column and connecting the fore limb to the thorax and neck, (ii) females had more of their total muscle in the flank or abdominal wall and less in the loin than males, and (iii) females tended to have less of their total side bone in the appendicular skeleton and more in the axial skeleton than males. However, the influence of the animal's sex on the amount of total muscle in the proximal parts of its limbs was significant in buffaloes but not in cattle; the reverse was true for the muscle group of the thorax and neck. The overall sex differences in bone-weight distribution for buffaloes were as small as previously reported for cattle, sheep and pigs. Features of better muscle-weight distribution in buffalo males as compared with females and in Egyptian buffaloes as compared with Australian buffaloes and British cattle breed types are discussed., (Copyright © 1982.

Twelve Egyptian buffalo, nine ♂ Friesian × ♀ Egyptian native Baladi (half Friesian) and nine ♂ Friesian × ♀ half Friesian (three-quarter Friesian) bulls were serially slaughtered between 161 and 560 kg for buffaloes and between 176 and 448 kg for cattle. Anatomical dissection data from the left sides of the carcasses were used to examine the growth of individual bones and bone groups. No significant genetic differences with respect to the growth patterns of bones relative to total side bone were reported, indicating that bones followed similar patterns in buffaloes and cattle. Differential growth of bones occurred following an increase of impetus from cervical vertebrae to os sacrum and with growth coefficients for bones of the forelimb correspondingly higher than for the hindlimb and the entire axial and appendicular skeletons following, respectively, late- and early-maturing patterns. Some significant, though minor, differences between buffaloes and cattle were found when weights of individual bones were adjusted to constant side bone weight. As compared with Friesian crosses, buffaloes had more weight of the ribs and less weight of the vertebral column in the axial skeleton, and more weight of radius-and-ulna and less weight of scapula in the forelimb at equal total bone. There were no significant differences between buffaloes and Friesian crossbreds in the proportion of total bone occurring in the entire hindlimbs and forelimbs and in the distribution of total bone between axial and appendicular skeletons., (Copyright © 1983.
