Abstract

The aim of the research was to evaluate the effect of growth rate of Large White breed to carcass traits and chemical composition of meat. The experiment consisted of three groups of pigs with different growth rates. Every group was individually evaluated and statistically compared with two standardized fattening sexes. It was found out that the group of gilts showed statistically significant differences between the averages of groups according to the growth intensity at the level P <0.05. Results showed significant differences between the averages of groups according to the growth intensity of both sexes in the indicator of the backat thickness and in the group of barrows in the weight of pork belly at the level P≤0.05. The parameters of chemical composition according to growth rate showed significant differences at the level P≤0.05 and also at the level P≤0.01 in the total protein content of the meat at both sexes.

Key Words: Growth rate, slaughter traits, sex, pigs
