Abstract

Cilj rada bio je analizirati podatke za plodnost svinja s gospodarstava na području Bjelovara te utvrditi osnovne reprodukcijske pokazatelje. Podatci za plodnost krmača i nazimica prikupljeni su tijekom svibnja i lipnja 2018. godine na šest obiteljskih poljoprivrednih gospodarstava sa šireg područja grada Bjelovara. Pasminski sastav na gospodarstvima uključuje čiste pasmine uključene u nacionalni uzgojni program za svinje: landras, veliki jorkšir i pietren. Prikupljeni podatci odnose se na pet prasenja čistih pasmina sa svakog od šest gospodarstava. Analizirane varijable su broj živooprasene prasadi, broj ukupnooprasene prasadi te broj mrtvooprasene prasadi. Rezultati sugeriraju visoku varijabilnost između gospodarstava u veličini legla koja je posljedica utjecaja okolišnih čimbenika na plodnost krmača. Najveća veličina legla zapažena je na gospodarstvima kod uzgoja pasmine landras dok je najniža plodnost, odnosno veličina legla zabilježena kod pasmine veliki jorkšir. Neovisno o razlikama unutar gospodarstava najveći broj živooprasene prasadi uočen je u trećem, a najmanji u petom leglu.

Abstract (english)

The aim of the study was to analyze the data for pig fertility on family farms in Bjelovar region in Republic of Croatia. Through the data analysis basic reproduction information was determined. The data for sow fertility was collected from May to June 2018. on six different family farms from wide spread of land surrounding city of Bjelovar. Breed composition included Landras, Large White, and Pietrain. Collected data is referred to five farrowings of purebreds from every one of the six farms. Number of piglets born alive, total number of born piglets and number of piglets born dead were analyzed. Results of the data analysis showed great difference in litter size among family farms, mostly due to environmental factors. The largest litters were found in Landras breed, whereas the smallest litter sizes were found in Large White breed. Independent on differences inside farms, the highest number of piglets born alive litter was found in third farrowing, whereas the lowest number of piglets born alive was found in the fifth farrowing.
