Abstract

Cilj istraživanja bio je utvrditi utjecaj pasmine i spola svinja na dnevni prirast u testu u proizvodnim uvjetima. Istraživanje je obuhvatilo 62 469 zapisa iz testa svinja u proizvodnim uvjetima od 1998. do 2017. godine u Republici Hrvatskoj. U istraživanje su bile uključene svinje četiri čiste pasmine: veliki jorkšir (VJ), landras (L), pietren (P), durok (D) te križanci VJxL te LxVJ. Oba promatrana utjecaja imali su značajan utjecaj (P<0,05) na dnevni prirast. Uočena je statistički značajna razlika u dnevnom prirastu između pasmina. Vrijednosti pokazuju da su svinje pasmine durok imale najveći dnevni prirast sa 583 g, zatim ih slijede križanci LxVJ sa 532 g i VJxL sa 529 g. Dnevni prirast za velikog jorkšira iznosi 528 g, a najmanji prirast je zabilježen kod pietrena sa 519 g. Utvrđena je značajna razlika (P<0,05) u dnevnom prirastu u testu u proizvodnim uvjetima između spolova (nerastića i nazimica) gdje prosječni dnevni prirast nerastića iznosi 569 g, a za nazimice 508 g.

Abstract (english)

The aim of the study was to determine the influence of breed and sex on daily gain in field test of pigs. The research included 62,469 data records of pigs in test from 1998 to 2017. Four pure breeds were included in the study: Large White (LW), Landrace (L), Pietrain (P), Duroc (D) and crossbreeds between LWxL and LxLW. Both studied effects had significant effect (P<0.05) on daily gain. The difference in daily gain between breeds was found to be statistically significant. Duroc pigs had the highest daily gain rate of 583 g, while average daily gains were 532 g and 529 g for LxLW and LWxL, respectively. The lowest average daily gain of 519 g was found in Pietrain. The difference in daily gain in field test between the sexes (young boar and gilts) was statistically significant (P<0.05). The observed average daily gain in young boars was 569 g and in gilts is 508 g.
