Abstract/ Executive Summary:

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 percent 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 a significant (p<0.01) species effect on leg and skin as percent 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.

Program Area: Comparative study

Commodity: Livestock, Meat

Objectives:

Quality and quantity of meat produced is generally a function of age, sex, genotype and management. The genotypic effect on carcass characteristics of different ruminant species has not been studied yet so far. With the above view, the objectives of this study was to look at the effectiveness of species on carcass characteristics concerning quality and quantity of different livestock widely used for meat production in Bangladesh.

Methodology:

Experimental animals and source of data The experiment was conducted on four different species i.e. goat, sheep, cattle and buffalo in the slaughter house of Mymensingh town and Animal Breeding & Genetics laboratory, BAU. A total of 32 goats, 21 sheep, 8 cattle and 9 buffaloes were evaluated according to sex and age. The empty stomach live weight of sheep and goat was taken by the help of loading balance but for cattle and buffaloes the following formula (McNitt, 1983) was used keeping the animals over night unfed.

Experimental animals and source of data The experiment was conducted on four different species i.e. goat, sheep, cattle and buffalo in the slaughter house of Mymensingh town and Animal Breeding & Genetics laboratory, BAU. A total of 32 goats, 21 sheep, 8 cattle and 9 buffaloes were evaluated according to sex and age. The empty stomach live weight of sheep and goat was taken by the help of loading balance but for cattle and buffaloes, the following formula (McNitt, 1983) was used keeping the animals overnight unfed.

Data recorded Data were recorded in terms of empty stomach live weight at slaughter, warm carcass weight, dressing percentage, visceral organs (heart, liver, lung, pluck, kidney, spleen) head, gut, leg, skin, blood, total edible products and by-products and total inedible by-products.

Chemical analysis Flesh sample (200 g) was taken from five different locations (i. e. neck, forequarter, hind quarter, back and flunk) of the carcass and mixed it thoroughly in order to draw the final sample. Then chemical analysis was done for moisture, crude protein (CP), ether extract (EE) and ash following the method given by AOAC (1975). Statistical analysis All the experimental data were analysed using "MSTAT" statistical programme to compute analysis of variance (ANOVA) for Completely Randomized Design (CRD). Duncan's New Multiple Range Test (DMRT) was done to identify significance among the treatment means.

Achievement/Findings:

From the above results of the trial it should be concluded that species or genotype may have little effect or no effect on meat quantity i.e. carcass characteristics of sheep, goat, cattle and buffalo. But in quality concerned there is no effect of species or genotype on carcass chemical composition among four aforesaid ruminants. Before drawing such a conclusion it should be mentioned that optimum age at slaughtering of animals of different species was not Possible to follow properly and there were higher number of male animals were slaughtered relative to females. It should also be mentioned that a number of animals for each species was not same.
