Comparative carcass characteristics of ruminant species in Bangladesh

The present study describes the effect of species on carcass yield and composition of goat, sheep, cattle and buffalo. This experiment was conducted on 32 goats, 21 sheep, 8 cattle and 9 buffaloes in the slaughter house of Mymensingh town and Animal Breeding and Genetics Laboratory, Bangladesh Agricultural University. Animals were slaughtered according to "Mohammedan" method by severing the Major vessels-of the throat by a transverse cut. The average age at slaughtering of goat, sheep, cattle and buffalo was 11.48, 11.32, 38.00 and 28.00 months and the dressing percentage was 43.73, 41.60, 44.02 and 42.64 respectively. There was no significant effect of genotype on the dressing percentage of the animals. The total average edible products and by-products for goat, sheep, cattle and buffalo were 58.18%, 55.23%, 57.24% and 58.32% respectively and it varied significantly (p<0.05) among the aforesaid species. All edible by-products (except heart) i. e. head, liver, lung plus trachea, pluck, spleen and kidney differed significantly (p<0.01 or p<0.05) as per cent of body weight among the four different species. The total average inedible by-products percentage for goat, sheep, cattle and buffalo were 42.13, 44.85, 42.68 and 40.21respectively and there was no significant variation on it among the species considered. There was significant (p<0.01) species effect on leg and skin as per cent of body weight while that for blood and gut it was not. In case of carcass chemical composition, the moisture content (%) was as 74.37, 75.27, 75.79 and 74.72; crude protein (%) as 21.52, 19.59, 20.18 and 20.41; ether extract (%) as 3.29, 3.25, 2.60 and 3.36; ash (%) as 1.23, 1.26, 1.07 and 1.15 for goat, sheep, cattle and buffalo respectively. There was no significant difference in the carcass chemical composition among the four species.
