REPRODUCTIVE TRAITS OF BLACK SLAVONIAN PIG - ENDANGERED BREED
Abstract
Black Slavonian pig is an autochtonous Croatian breed originated by crossing of the breeds Mangulica, Berkshire and Poland Chine at the end of 19th and beginning of 20th century. It belongs to the group of fat-meaty breeds. Due to a small number of the animals (153 sows, 45 gilts and 15 boars – Report HSSP, 2000) it is subjected to extinction danger. The investigation was conducted with 60 sows, inseminated by the total of ten boars at a family farm in eastern Slavonia. Black Slavonian sows farrowed 7.10 piglets per litter of which 6.31 were alive. They reared 5.71 piglets, aged two months, in a litter. Significant variability of the reproductive traits and their statistically important phenotypic correlation (r) were determined in the analysed sows.
