Reproductive performance of crossed pramenka with Wirtemberg depending of breeding conditions

Abstract

In this paper are analyses reproductive performance of crossed pramenka with wirtemberg of the farm "Dubočani". Fertility of sheep's was from 113,4 to 132,4 percentage. Mortality was from 13,3 to 23,6 percentages. Singles at birth had average body weight of 3,87 kg. Twins had 3,43 kg. Difference between this two categories was statistically high significant (P lt 0,01). Having it in mind twins had higher total meet production. This results have significant influence on rentability of sheep production.

U radu su analizirani reproduktivni pokazatelji oplemenjene pramenke sa virtemberškom rasom u zavisnosti od uslova odgajivanja. Plodnost ovaca kretala se od 113,38 do 132,36%. Procenat ojagnjenih od broja pripuštenih kretao se od 62,73 do 79,94%. Mortalitet jagnjadi se kretao od 13,28 do 23,6%. Jedinci pri rođenju su imali prosečnu telesnu masu od 3,87 kg, a blizanci 3,43 kg. Razlika od 0,44 kg ili 11,37% u korist jedinaca bila je statistički vrlo značajna (P lt 0,01).
