An Influence of Duroc Breed in Paternal Position on Carcass Value and Business Classification by SEUROP System in Hybrid Pigs

Popis výsledku v původním jazyce

The aim of this study was to establish the impact of genotype on the carcass value of tested slaughter pigs of the hybrid combination (Czech Large White x Czech Landrace) x Duroc. The slaughtered test animals had an average slaughter weight of 119.68 +- 12.37 kg, the average lean meat portion of the carcasses established by classification was 56.20 +- 3.15 %, the average backfat thickness was 17.13 +- 4.10 mm. An average 3.63% of intramuscular fat in the longest back muscle was found in all the monitored slaughter pigs. The highest percentage of carcass pigs 54.3 % (398 animals) were classified in business class E with 57.51 +- 1.32% of lean meat portion, 115.15kg of an average slaughter weight. The lowest number of pigs (3 animals) were classified into business class O with 43.83% of lean meat portion. From results it is evident that with decrease of lean meat portion the slaughter weight of carcass pigs was growing. Carcass pigs classified into business class E reached the highest average price (32.86 CZK) per 1 kg of carcass body. A low negative correlation of r = -0.25, statistically conclusive on the level of importance of P &lt; 0.05, was registered between slaughter weight and lean meat content. A very high negative correlation of r = -0.95, statistically conclusive on the level of importance of P &lt; 0.001, was established between the thickness of backfat thickness and the lean meat portion.
