Sperm morphology and in vitro viability in diluted semen in relation to fertility of AI boars.
Examination of sperm morphology and assay of in vitro sperm viability by use of a thermoresistance test, incubation with ouabain and assay of ASAT-release was performed in 10 ejaculates from each of 10 boars during a 7-month period. The boars were routinely used for AI during the period and the results of the various laboratory assays were related to the fertility of the boars.
