Abstract

Cilj ovog rada bio je utvrditi porodnu masu i dnevni prirast janjadi travničke pramenke uzgajane na području Bilogore. Istraživanjem je bilo obuhvaćeno 94 janjadi oba spola od čega 49 muške i 45 ženske, u razdoblju od janjenja do navršene prosječne dobi od oko 70 dana. Istraživanjem je utvrđena neznatno veća prosječna porodna masa muške (4,61 kg) u odnosu na žensku janjad (4,38 kg) travničke pramenke. Međutim, u muške je janjadi utvrđena statistički značajno veća završna tjelesna masa i prosječni dnevni prirast u odnosu na žensku janjad (P<0,01). Utvrđena prosječna porodna masa samaca bila je statistički značajno veća (P<0,01) od prosječne porodne mase blizanaca (4,66 kg : 3,89 kg). Veličina legla nije statistički značajno utjecala na dnevni prirast janjadi. Istraživanjem je utvrđen utjecaj interakcije spola i veličine legla, pa su tako muški samci imali najveće vrijednosti porodne mase, završne tjelesne mase, apsolutnog i dnevnog prirasta, dok su u ženskih blizanaca navedene vrijednosti bile najniže.

Abstract (english)

The aim of this study was to determine the birth weight and daily gain of Travnik pramenka lambs raised in the area of Bilogora. Research included 94 lambs of both sexes, of which 49 male and 45 female, in the period from birth to an average age of about 70 days. In this study slightly higher average birth weight of male (4.61 kg) compared to female lambs (4.38 kg) of Travnik pramenka was determined. However, in male lambs, statistically significant higher final body weight and average daily gain was found compared to female lambs (P <0.01). The determined average birth weight of singles was statistically significant higher (P <0.01) than the average birth weight of twins (4.66 kg : 3.89 kg). Litter size did not statistically significant affect the daily gain of lambs. Influence of the interaction of sex and litter size was determined, so that male singles had the highest values of birth weight, final body weight, absolute and daily gain, while in female twins these values were the lowest.
