Abstract
Objective of our research was to determine the correlation between quantity of meat, fat and bones in carcass with same tissues in three rib cut and quantity of muscle tissue in carcass with surface of M. longissimus dorsi. Investigation was carried out on male fattening young bulls of Domestic Spotted breed of average weight prior to slaughtering of 503 kg, and by total dissection total quantity of muscle, fat and bone tissue in carcass was determined. Correlation between mass of muscle tissue in carcass and mass of muscle tissue in three rib cut of carcasses weighing in average 284 kg was r=O.69, which means strong and positive. Correlation coefficient between mass of fat and bone tissue in carcass and mass of fat and bone tissue in three rib cut for same group was r=0.65 for fat tissue and r=0.53 for bone tissue. Correlation between mass of muscle tissue in carcass of average mass of 284 kg and cross section surface of M. longissimus dorsi on cut of 11. rib was r=0.80.
Cilj naših istraživanja je bio da se ispita povezanost količine mesa, loja i kostiju u trupu sa istim tkivima u trorebarnom odresku i količine mišićnog tkiva u trupu sa površinom M. longissimus dorsi. Ispitivanje je sprovedeno na muškim tovnim junadima domaće šarene rase prosečne mase pre klanja 503 kg. a totalnom disekcijom je utvrđena ukupna količina mišićnog. masnog i koštanog tkiva u trupu. Povezanost između mase mišićnog tkiva u trupu i mase mišićnog tkiva u trorebarnom odresku trupova prosečne mase 284 kg je r=0.69, znači jaka i pozitivna. Koeficijent korelacije između mase masnog i koštanog tkiva u trupu i mase masnog, odnosno koštanog tkiva u trorebarnom odresku za istu grupu iznosio je r=0.65 za masno tkivo i r=0.53 za koštano tkivo. Povezanost mase mišićnog tkiva u trupu prosečne mase 284 kg sa površinom poprečnog preseka M. longissimus dorsi na preseku 11. rebra iznosila je r=0.80.
