Zusammenhang zwischen Fertilität und Kopfschwanzkoppelung bei Eberspermien

Abstract: Relationship between the implantation of the tails and the fertility in boars In this study ejaculates of 47 different breed and age boars were examined. The aim of this study was to determine the relationship between the implantation of the tails and the fertility in boars. From the evaluation of 115 ejaculates it was observed that the rate of abaxial implantation of the tails in ejaculates of boars was very fluctuating. The rate of axial and abaxial implantation of the tails was stable in the ejaculates of the same boars. Although some studies indicate that abaxial implantation can be the reason for infertility the present authors observed better fertilisation results with ejaculates having higher percentages of abaxial spermatozoa.
