Abstract

Cilj rada je bio proučiti i utvrditi čimbenike plodnosti banijske šare svinje (sezona pripusta, utjecaj gospodarstva, redni broj prasenja i nerasta). Istraživanje je provedeno na 298 zapisa o prasenju krmača banijske šare svinje prikupljenih na 136 životinja u razdoblju od 2014 do lipnja 2019. godine na više gospodarstava u području Banovine i okolice. Statističkom analizom utvrđen je statistički značajan utjecaj sezone prasenja, gospodarstva, te rednog broja prasenja, dok utjecaj nerasta nije bio statistički značajan. Nakon statističke obrade podataka, utvrđen je postepeni rast broja živooprasene prasadi nakon svakog sljedećeg prasenja sve do petog prasenja. Utjecaj sezone manifestira se kroz kratkoročne (klimatske) i dugoročne (promjene u tehnologiji proizvodnje) utjecaje. Utvrđene su statistički značajne razlike u broju živooprasene prasadi između gospodarstava, što upućuje na razlike u tehnologiji i uvjetima držanja svinja. Razlike se kreću od 4 do 6 prasadi u leglu. U budućnosti bi trebalo poboljšati plodnost banijske šare svinje s ciljem dobivanja većeg broj legala uz veću veličinu legla, čime se može utjecati na ekonomičnost uzgoja ove pasmine. Dobiveni rezultati ukazuju na visoku varijabilnost u broju živooprasene prasadi u banijske šare svinje.

Abstract (english)

The aim of the study was to determine the factors (mating season, the herd, parity, and boar) that influence litter size in Banija spotted pig population. The study was conducted on 298 farrowing records from 136 Banija spotted sows collected between 2014 and June 2019 at several herds in the area of Banovina and its surroundings. Statistical analysis revealed statistically significant effect of the farrowing season, herd, and parity, while the impact of boar was not statistically significant. After statistical analysis, a gradual increase in the number of live piglets was observed after each subsequent farrowing until the fifth parity. The effect of the season is manifested through short-term (climate) and long-term (changes in production technology) changes in litter size. Significant differences in the number of liveborn piglets between herds were found, indicating differences in technology and production conditions. The differences range from 4 to 6 piglets per litter. In the future, the fertility of the Banija spotted pigs should be improved in order to obtain more litters with a larger litter size, which may positively affect the breeding efficiency of this breed. The results obtained indicate a high variability in the number of live piglets in pig swine.
