Effect of different genotypes, sires and season of slaughtering on slaughter traits of pigs

Abstract

The effect of different genotypes, sires and season on age at slaughtering mass of warm carcass sides, fat thickness measured on three points (withers back, rump) and percentage of meat in warm carcass sides of average mass of 74,17kg using Yugoslav standard method was investigated in this paper. Results obtained show that investigated traits had no variation between pigs of different genotype (P>0,05). Sires effected variation of age at slaughtering, fat thickness (withers, back, rump, back + rump) and percentage of meat in warm carcass sides of offspring (P (lt) 0,01). Slaughter season effected fat thickness measured on withers (P (lt) 0,01) and age at slaughtering (P (lt) 0,05). Age, fat thickness and percentage of meat depended on the mass of warm carcass sides. Evaluated heritability coefficients for investigated traits were in interval of medium to high.

U ovom radu ispitivan je uticaj različitih genotipova, očeva i sezone na uzrast pri klanju, masu toplih polutki, debljinu slanine merene na tri mesta ( greben, sredina leđa i krsta) i procenat mesa u toplim polutkama prosečne mase 74,17 kg, primenom Jugoslovenskog standarda. Rezultati koji su dobijeni pokazuju da ispitivane osobine nisu varirale između grla različitih genotipova (P>0,05). Očevi su uticali na variranje uzrasta pri klanju, debljinu slanine ( greben, sredina leđa, krsta, leđa + krsta) i na procenat mesa u toplim polutkama potomaka ( P (lt) 0,01). Sezona klanja uticala je na debljinu slanine izmerenu na grebenu ( P (lt) 0,01) i na uzrast pri klanju ( P (lt) 0,05). Uzrast, debljine slanine i procenat mesa zavisili su od mase toplih polutki. Ocenjeni koeficijenti heritabiliteta za ispitivane osobine su bili u intervalu od srednjih do visokih.
