Effect of two mycotoxin adsorbents with different mechanisms of action were followed in 180 purebred and terminal combination boars reared in artificial insemination stations. The following parameters of boar sperm quality were investigated: volume in millilitres, concentration and motility, and numbers of pathological spermatozoa. When processing the boar semen, the dilution ration and numbers of AI doses were recorded. Compared were two preparations: in case of Preparation 1 the number of evaluated ejaculates was 1,037 while in case of Preparation 2 altogether 1,109 ejaculates were evaluated. Boars receiving diets with Preparation 1 produced more voluminous ejaculates (by 4.1 ml) and their concentration of spermatozoa was also higher (by 39 thous./ml; P ≤ 0.001). Dilution parameters were better as well and numbers produced of AI doses were also higher. In case of Preparation 2 the motility of spermatozoa was a higher while the numbers of sperms were lower. The obtained results demonstrated that a suitable adsorbent can show a positive effect on both quantitative and qualitative parameters of boar sperm.
