Artificial insemination with diluted and undiluted fresh semen in goats

Abstract

The objective of this study was to compare the fertility levels of goats inseminated with fresh semen and buck semen diluted with three different extenders. The fertility rates of goats inseminated in spontaneous oestrus during breeding season were found 66.6% (12/18), 60.8% (28/46), 44.4% (12/27) and 48.7% (20/41) for fresh semen, Laiciphos 488-egg yolk, sodium citrate-glucose-egg yolk and sodium citrate-egg yolk extender respectively. Reproductive performance did not differ significantly between females inseminated with undiluted or diluted semen. It is concluded that diluted buck semen with these diluents can be used successfully during the goat breeding season for inseminating does.
