Records of alive weight, weight of carcass, weight of primary cuts and income of
carcass, proceeding from the Company Scope Ltda, located in the district of Icoaraci, Located
in Belém-Pará, had been used to discriminate possible differences between bubaline and
bovine, abated females during the year of 2007. The registers of alive weight had been used to separate the sample in light and weighed
females, separately in each species, using as threshold the corresponding value the median of
the alive weight in each species. Thus, four groups of females, bubalinas and bovine, light and
weighed had been composites. For comparison between female vectors of averages of the weights alive, weights hot
carcass, left and right hot carcass, weight of the cold carcass, front weight, back weight,
weight tip-of-needle and weight leather, between bubaline and bovine, light and weighed, it
was used procedures of multivaried inference. The results had disclosed the heterogeneities for the weight of abate of the animals,
inside and between species, having a clear-cut standard of ideal weight to it does not abate it. Bubaline had gotten greaters weights for carcass component, when compared with the females
of the bovine group. Excepting the weight of the cold carcass and the tip of needle, bubaline
of the group weighed, had gotten comparative average greater when to the light group. Inside
of the group of bovine females it did not have difference statistics for the weight of carcass
cold (P<0,01). It is verified that, in average, bovine had presented greater income, except for the front. The intra-racial Groups had been presented significantly different between itself (P). On the
other hand, it was not verified intra-racial differences for the incomes of carcaças hot, cold
carcass, front and back pernil.
