Sažetak
Knowledge of the protein content in carcass of pigs of different size and age becomes essential since meat is used to feed people and to use in different products for human consumption. As we all know, protein contains appropriate amino acids necessary to optimize cell life and mitosis and life longevity in humans. Experiments were done on two farms on pigs of different body weight: 10-15 kg; 24-30 kg; 55-65 kg, 105 – 115 kg and 125 -140 kg. In each category we analyzed 6 animals
from each 2 sires, in total 30 pigs from 12 sires. The meat for analysis was taken at 4 locations: neck, shoulder, MS (musculus semimembranous) and MLD (musculus longisimus dorsi). The selection criteria for all were the same. They belonged to Landrace and Yorkshire, mother’s line where 69% of selection focused on litter size
and milk production. All pigs had adequate feed without fishmeal and sunflower. The basic feed contained: corn, wheat, barley and soybean. The piglets at 10-15 kg had 24.4% of protein; animals of 24-30 kg had 26.6% of protein in meat. Pigs between 55 and 65 kg had 24.1%, pigs between 105 and 115 kg contained 23.2% of protein and the oldest at 125-140 kg had 22.4% of protein. Following world meat quality standards, all animals in different categories were within them. It also means selection criteria we used were efficient. The variations of protein content in each category, although small, were between 11 and 14%. The influence of age and sire on examined traits was highly significant while differences between farms were not. This justify was than use of MME model which can be used in selection to improve
certain traits.
