Increasing of economic rate of sheep production using new biotechnological methods

Abstract

In this paper in fluence of post application of nation gonadotropin was analyzed The amount of 250 i.j. PMSG per individual 16 days from first fertilisation on number of lambs. Trial group shown increasing of number of lambs for 34 lambs. Number of lambs pretreated sheep was 1,03 at trial grup and 0,63 lambs at control group. Trial group had higher fertility of 5,35%. According to type of lambing trial group had more singles for 11 individuals twins for 20 individuals and triplets for 3 individuals. Wit the application of the next dose of gonadotrpin resulted in increasing of twining and higher production of lambs meat. At the same time, Economis rate of sheep production.

Reprodukcija predstavlja ključni faktor u rentabilnosti ovčarske proizvodnje Osnovni preduslov za unapređenje i intenziviranje ovčarske proizvodnje leži U primeni savremenih saznanja iz oblasti fiziologije reprodukcije. Cilj ovog Rada je bio da se utvrdi uticaj naknadnog davanja gonadotropina posle uobičajenog tretmana sa progestagenom + PMSG na reproduktivne performanse ovaca. Kontrolna grupa tretirana je uobičajeno a ogledna je pored ovog 16 dana Dobila još 250 i.j. gonadotropina po grlu. Ogledna grupa je imala znatno Više jagnjadi od kontrolne.
