Autochthonous Balkan goat breed: Composition and traits of kid carcass

Abstract

Investigations were realized within the program of protection of genetic resources of autochthonous goat breeds - Balkan goat breed. Trial was carried out on farms of individual producers, breeders on the territory of Svrljig region, on 12 male kids of average age of 63 days and average body mass prior to slaughtering of 10,54 kg. Objective of the research was to determine the meat yield (dressing percentage), share of by products of in body mass prior to slaughtering and in processed carcass, commercial value of carcass (by evaluation of conformation, covering of carcass and kidneys with fat tissue, colour of meat and tallow) and share of main carcass parts. Results of the research indicated that kids of Balkan goat breed at stated age have average body mass of 10,54 kg and yield of warm carcass with head and giblets of 58,89%, which is high value and is within the limits for yield realized by kids of approximate age of pure goat breeds. Shares of slaughter by products (rumen, small intestines, skin, abomasus), giblets (liver, lungs, heart, spleen, kidneys), fat tissue (peritoneum, kidney, mesentherium) and head in cooled carcass are also within the limits realized by kids of pure goat breeds. Commercial value of carcass, established based on assessment of conformation (scored as good), covering of carcass and kidneys with fat tissue (scored as medium), colour of meat and tallow (scored as very good) is good and within the values realized by kids of pure goat breeds. Quality of carcass evaluated based on share of main carcass parts of category I (thigh, loin part) of 33,41%, category II (back, shoulder, neck) of 38,68% and category III (breast, second fore thigh, second thigh) of 26,91%, was very good. Muscle, fat and binding tissue (meat in narrow sense) made 2/3, whereas bones made 1/3 of the mass of three rib cut, which is also very good. Ratio of muscle and fat tissue was also very favourable - 5,08.
