TEFC-Total external fat cover; TIFC-Total internal fat cover; TFT-Total fat cover Graph 2. Differences between genotypes in fat cover Presence of fat in pelvic cavity was more distinct in crosses with Charolais (3,34) and Limousine (3,28), where also the cover of kidneys with fat was better (3,50 and 3,53) compared to domestic breed (3,17). These significances were also significant at the level of p
144 Conclusion D. Ostojić-Andrić et al. Based on previously presented results it can be concluded that crossing of domestic Simmental breed with French fattening breeds resulted in significant improvement in conformation in F1 crosses, especially in regard to high quality sections (round, back and loin). Fat layers on outside carcass were significantly greater in domestic Simmental cattle compared to crosses with Charolais. Despite the aforementioned, positive effects of fat cover on the carcass quality, this can not be considered desirable from the standpoint of fat content in carcass and the meat given the high correlation of these two properties. In regard to total internal fat cover of carcass, no statistically significant differences were established between genotypes. However, it can be concluded that distribution of fat tissue in depots between domestic breed and crosses varied. Also, whereas in case of domestic Simmental cattle fat is deposited in chest cavity, in crosses this occurred in pelvic cavity, which resulted in better cover of kidneys and better grading of the carcass quality.

Uticaj ukrštanja domaće simentalske rase i francuskih tovnih rasa na konformaciju i prekirvenost junećih trupova lojem D. Ostojić-Andrić, S. Aleksić, M.M. Petrović, S. Hristov, V. Pantelić, Ž. Novaković, D. Nikšić Rezime Ocena konformacije i prekrivenosti junećih trupova lojem ima veliki značaj u savremenim sistemima ocene kvaliteta trupova. Na ovaj način postiže se odgovarajuća cena za svaku klasiranu polutku prema zahtevima potrošača. U ovom radu ispitivan je uticaj eksperimentalnog ukrštanja domaće simentalske rase sa šarole i limuzin rasom (N=96) na konformaciju i prekrivenost junećih trupova lojem. Ispitivanje je obuhvatilo ocenu pomenutih osobina na celim trupovima kao i parcijalno na određenim delovima trupova a prema odgovarajućoj linearnoj skali ocene (1-5). U odnosu na ocenu konformacije trupova utvrđene su statistički
