Sažetak
Fattening traits and carcass quality of BL X (VJNJLDL) and DL X (VJNJLDL) crossbreeds and Hypor pigs fattened in the same conditions and also fed at will, from 25 to 104 kg of body weight, were investigated. Dissection of the carcasses was carried out
according to the method of Weniger et al. (1963). In order to achieve the same body mass in pigs the duration of the fattening period varied, depending on the intensity of gain and the genotype. The daily gain in pigs genotype BL x (VJNJLDL) was a little higher than in Hypor pigs and DL X (VJNJLDL). The gain in muscle tissue was the highest in the carcasses of DL x vjJNJLDL) pigs, followed by Hypors and DL X (VJNJLDL) pigs (35.04, 34.46 and 33.92 kg). The muscle tissue in the final weight of pigs followed the same order, i.e. 33.45, 33.43 and 32.58 kg. Correlation and regression analyses show that the phenotype connection and dependence of fattening traits (gain and duration of fattening period) as well as the quality of carcasses (gain in muscle tissue, fat tissue with skin and bones) are characteristic of every pig genotype. Linear, aquare, potential
and exponential equations were established depending on the type of connection and occurence in the sample. The two created phenotypes of pigs [BL X (VJNJLDL) and DL X (VJNJLDL)I are suitable for meat production considering the fattening traits and carcass
quality, while in some qualities they exceed those of hypor pigs.
