Sažetak

Cilj ove studije bio je da se utvrdi uticaj primenjene metode kvaliteta trupa kod 201 potomka, oba pola (n = 108 kastriranih mukih grla i n = 93 ženskih), ispitivanih očeva nerastova. Za određivanje prinosa mesa (JUS1) i udela mesa (JUS 2) u polutkama, na osnovu izvršenih merenja, korićene su tabele za mesnate svinje, koji su sastavni deo Pravilnika o kvalitetu zaklanih svinja i kategorizaciji svinjskog mesa (SG SFRJ, 1985). Udeo mesa (EC 94 i EC 06) određen je na ohlađenim levim polutkama metodom delimične sekcije (prema metodologiji preporučenoj od strane EU - Walstra i Merkus, 1996). Istraživanje je sprovedeno na svinjarskoj farmi i u eksperimentalnoj klanici Instituta za stočarstvo Beograd-Zemun. Smeštaj, nega i ishrana životinja bili su u skladu sa tehnologijom uzgoja u ispitivanom zapatu. Prosečan udeo mesa utvrđen primenom Pravilnika (JUS2) iznosio je 43,58% sa nižom apsolutnom varijacijom u poređenju sa uredbom EU iz 1994. (EC 94; 53,56%) i iz 2006 (EC 06; 56,55%). Procenjeni sadržaj mesa primenom Pravilnika (JUS 2) bio je za 9,98% niži u odnosu na uredbu EC 94 i za 12,97% niži u odnosu na EC 06. Ako govorimo o izboru potomstva za uzgoj, ako uzmemo u obzir samo procenjenu mesnatost, vidimo da unutar rase L imamo visoke i veoma značajne (P <0,001) razlike između očeva za procenjeni sadržaj mesa u skladu sa EC 94 i EC 06. Implementacijom novih metoda procene sadržaja mesa (EC 94 i EC 06), utvrđen je veći udeo mesa (9,98%, odnosno 12,97%) u poređenju sa Pravilnikom (1985). Ovo istraživanje ukazuje na neophodnost promene postojeće metode utvrđivanja sadržaja mesa svinja u Republici Srbiji.
