The influence of breed and sex on tissue distribution in pig carcasses

Abstract

The aim of this study was to determine differences in the distribution of certain tissues (muscle and adipose tissue and bone) in carcasses of male and female animals. The paper included two fertile breeds: Yorkshire and Landrace and Hampshire breeds as terminal. Carcass dissection was performed by model EU 1992. During dissection data was collected about: weight of animals at slaughter, weight hot and cold carcass, less valuable parts, weight and proportion of the back, the neck, thigh, belly, shoulders the carcass, and the share certain tissues (muscle, fat and bone) on the carcass. Carcass weight in male animals was 40.66 kg with fat thickness on the back of 24.54 mm and 30.58 mm on the ramp, while in the female animal carcass weight was 40.37 kg, the thickness of fat on the back 21.49 mm and 26.71 mm on the ramp. Comparing the proportion of muscle tissue in the carcass of male and female animals was statistically significant difference (P <0.05). Comparing within the breed, no statistically significant differences (P> 0.05) in the percentage of meat between two fertile breeds (Landrace and Yorkshire), while there is a statistically significant difference (P <0.05) between the two fertile breeds and terminal (Hampshire). The share of meat in the carcass of female animals was 56.94%, while the males had a lower percentage of meat, 54.82. Sex and breeds have highly significant effect on the amount of meat on the carcass.
