Procjena reproduktivne uspješnosti u koza – pregled odabranih čimbenika koji na to utječu

Abstract

Dairy goats are a very successful form of livestock farming in developing countries, with functional products for human consumption, which makes their breeding attractive. Breeding efficiency is determined by successful reproductive parameters. Several parameters can be used as indicators of reproductive success, such as the number of kids born, age at first kidding, kidding interval, percentage of kids born and weaned, abortion rate, body weight of kids at birth and at weaning, and the length of the goat's reproductive life. Due to the seasonality of reproduction and multiple possibilities of controlling the sexual cycle in goats (hormonal and non-hormonal methods), it is difficult to standardise parameters that could be systematically used to detect suboptimal production, and whose improvement would increase reproductive success. Adequate housing conditions and feeding are inseparable from good breeding and productivity of animals. By meeting these measures with constant observation of reproductive success parameters, high fertility, large litters (2 kids per pregnancy) with a survival rate of 90% until weaning can be expected in goat breeding.
