EFFECT OF FEEDING SYSTEM IN RELATIONSHIP TO FATTENING AND PRODUCTION PARAMETERS FROM MANGALITSA BREED
Nowadays it is a trend in the market of pork to create products based on traditional specialities and these products require a specific meat quality with emphasis on dry matter content, intramuscular fat content in meat and fatty acid composition. The aim of this study was to verify the intensive feeding system in fattening of Mangalitsa breed from the point of view of improving fattening and slaughter parameters. In the study, sixteen pcs of Mangalitsa breed were used. The pigs were divided into two groups. The first group was fed under the intensive conditions (G1), where the pigs received complete feed mixture for fatteners by ad libitum system. The second group was fed under the semi-intensive conditions (G2), where the Mangalitsa breed received feed mixture with restraint twice a day. The fattening period lasted from 30 kg to 100 kg. The G1 had higher average daily gain, lower feed intake as well as feed consumption efficiency compared to G2 (P < 0.05). In general, the G2 had lower slaughter yield, but significantly longer carcass length (P < 0.05) compared to G1. The G1 had higher weight of shoulder, but lower weight of neck (P < 0.05), loin, thigh as well as lower percentage of lean meat cuts and meat from the thigh compared do G2. The loin eye area was also significantly lower in G1 than in G2 (P < 0.05). Regarding differences between fat parts from pigs, the G1 had higher backfat thickness and percentage of carcass fat than G2. It can be concluded that indigenous breed Mangalitsa can be reared in the intensive conditions, where the fattening parameters were improved and quality of carcass was not significantly changed.
