Abstract

The study included the progeny of three boar-sires breeds (SL - Swedish Landrace; LW - Large White and P - Pietrain). A total of 201 progeny of both sexes (93 female and 108 male castrated animals), originating from 16 boar-sires, were tested. The study included the progeny of 10 SL boar-sires (sires nuRWer: 1, 2, 3, 7, 8, 9, 15, 16, 17 and 18), progeny of 3 LW sires (sires nuRWer: 4, 5 and 6) and 3 P boar-sires (sires nuRWer 14, 19 and 20), born in four seasons (winter, spring, summer and autumn). Studies have shown that, with an mean weight of a warm carcass side of 81.20 kg, the highest mean values for ham weight (RW; 10.456 kg), mass of intermuscular fatty tissue (RINT; 0.477 kg), ham bone (RB; 0.837 kg) and muscle tissue RMT, 7,939 kg) have progeny of the sires of Pietrain breed (P) compared to SL and LW sires. In comparison to animals sired by SL and LW boars, the progeny of P sires had less skin and subcutaneous fat tissue (RSFT) by 30 and 549 grams. Studies have shown that we have progeny of sires 7 and 9 of SL breed which have the lowest LSMean values for the yield of skin and subcutaneous fat tissue (869 and 876 g), which is below the mean for breed by 364 and 357 g. In addition, when it comes to intermuscular fatty tissue, the lowest established value was recorded in the progeny of sire no. 8 of SL breed (182 g), which is by 220 g less than the general mean and by 132 g below the mean of the sire breed. The animals originating from sires n. 19 and 20 showed the highest weight of muscle tissue (RMT) (8.489 and 8.118 kg) in the ham, which is by 2.853 and 2.482 kg more meat compared to the progeny of sire no. 5 of LW breed. The total weight of the ham and the ham muscle yield were influenced by (P <0.01 and P <0.001) sire breed, sires within the breed, gender and season of birth. A very significant (P <0.001) influence of the weight of warm carcass sides on the ham weight and tissue yield was determined.

Summary

Introduction

The quality traits of pig carcass sides and pig meat varied under the influence of a large number of factors. Selection may influence the content of intramuscular fatty tissue, or the content of fat in meat (Dević and Stamenković, 2004). In regard to the effect of sex on the quantity of fat tissue in the pig carcasse, Čepin and Žgur (2003) state that uncastrated male animals, compared to females, have a much lower percentage of fat under the same diet regime. They state that the selection is a powerful tool for reducing fat content, and that adequate animal nutrition provides the ability to reduce fat content and fatty acid changes.
