Abstract

Cilj rada bio je utvrditi neke odlike rasta (porodna masa, dnevni prirast, relativni prirast, završna tjelesna masa) odabrane muške jaradi izvornih (hrvatska šarena koza i hrvatska bijela koza) i inozemnih pasmina koza (alpina, sanska, srnasta i burska koza). Istraživanjem su prikupljeni podaci dobiveni provedbom performance testa odabrane muške jaradi u field uvjetima u razdoblju od 2011. do 2017. godine. Ukupno je istraživano 650 jaradi. Utvrđen je značajan (P<0,001) utjecaj pasmine na sve istraživane odlike rasta jaradi. Jarad inozemnih pasmina imala je veću (P<0,001) prosječnu porodnu masu te je ostvarila veći (P<0,001) prosječni dnevni prirast i prosječnu završnu tjelesnu masu nego jarad izvornih pasmina. Najveća prosječna porodna masa (3,83 kg) i najveća završna tjelesna masa (27,04 kg) utvrđena je u jaradi srnaste koze. Utvrđen je značajan (P<0,001) utjecaj sezone jarenja na porodnu masu, relativni prirast i završnu masu jaradi. Godina jarenja nije imala signifikantan utjecaj na prosječnu završnu masu niti dnevni prirast jaradi, ali je imala značajan utjecaj na prosječnu porodnu masu i relativni prirast jaradi.

Abstract (english)

The purpose of this paper is to determine some of the growth traits (birth weight, daily gain, relative gain and final body weight) of selected male goat kids of indigenous (Croatian White Goat and Croatian Spotted Goat) and foreign breeds of goats (Alpine, Saanen, German Improved Fawn and Boer). The research gathered data obtained by carrying out the performance test of the selected male kids in field conditions in the period from 2011 to 2017. A total of 650 male goat kids were studied. Significant (P<0.001) effect of the breed on all investigated growth characteristics was found. Goat kids of foreign breeds had significantly (P<0.001) higher average birth weight, daily gain and final body weight than the goat kids of indigenous breeds. The highest average birth weight (3.83 kg) and the highest final body weight (27.04 kg) were found in German Improved Fawn’s kids. Significant (P<0.001) effect of the kidding season on the birth weight, relative gain and final body weight was found. The age of kidding did not have a significant effect on the average final body weight or the daily gain of the goat kids, but had a significant effect on the average birth weight and the relative gain of the goat kids.
