“…In all forms of the equation, carcass weight accounts for the majority of the total variance. This is in agreement with results generally obtained and with those obtained by the present authors working with Mexican commercial quality cattle (Butterworth et al 1974). It is unusual, however, that the linear form of the evaluation gives a more accurate prediction than the allometric form (see Seebeck, 1968, and results of Butterworth et al 1974).…”

“…The high dependence on body weight in both the present and the previous (Butterworth et al 1974) studies could well reflect the low fat deposition in both types of animals as Everett (1963) has shown that the two factors of greatest importance on the yield of edible meat are carcass weight and fatness.…”

SUMMARYMeasurements were made on 104 carcasses of Holstein or Holstein cross-bred calves in a commercial slaughterhouse and retail butchers in Monterrey, NL. Measurements were: chilled carcass weight, circumference of side, maximum depth of forequarter (three measurements), length of leg, length of side, and length of forearm. Carcasses were cut and the sum of the weights of round, rump, short loin and rib (all bone in) defined as ‘high-priced cuts’. Multiple regressions were computed for linear, semi-allometric and allometric equations using a CDC 3300 computer.The linear form of the equation accounted for more of the total variance than either the semi-allometric or allometric forms. In all equations cold carcass weight accounted for the greater part of total variance (98·9, 97·1 and 98·2% respectively for the three equations in the order as mentioned above). The incorporation of circumference of side slightly improved the goodness of fit in all cases as did the inclusion of length of side and length of leg in the semi-allometric form. The particularly high proportion of the total variation attributable to cold carcass weight in the present study was probably due to the sparse fat cover of the calves.

Objective: An experiment was conducted to evaluate the effects of increasing levels of spineless cactus (0%, 33%, 66% and 100%) used as a substitute for wheat bran energy concentrate in buffalo diets on quantitative and qualitative traits of the meat and carcass.Methods: Twenty Murrah buffaloes at 18 months of age, with a mean initial weight of 292.9±57.3 kg, were randomly allocated to four treatments with five replicates. The animals were slaughtered after 90 days in the feedlot. The effects of spineless cactus as a replacement for wheat bran energy concentrate in the diet of the buffaloes on the carcass and meat traits, slaughter weight, carcass yield and carcass measurements were studied.Results: Dry matter intake (DMI), feed conversion (FC), average daily gain (ADG), hot carcass weight and carcass compactness were negatively affected (P<0.05) by the increasing replacement levels Increase spineless cactus levels led to linear reduction in average daily gain, slaughter weight, hot and cold carcass weight, compactness index and in the amount of muscle in the carcass, and there is isno difference between the control treatment and the 33% replacing level for these parameters. The quality of the meat was not influenced by the treatments.; however, replacement levels of up to 33% resulted in a larger edible portion of the carcass. Considering the evaluated qualitative parameters, all treatments provided meat of excellent quality, with no effect (P>0.05) of the replacement levels on the evaluated traits. Conclusion:Spineless cactus can replace wheat bran by up to 33% in sugarcane-based diets for buffaloes, without influencing quantitative and qualitative traits of the meat and carcass. spineless cactus associated with urea can replace up to 33% of the energy concentrate in sugarcane-based diets used in the finishing of feedlot buffaloes.
