The boars of Duroc breed and Duroc x Hampshire and Duroc x Pietrain crossbreds received vit. C at a dose of 2.5 and 3.6 g/animal/day for 30 days. Prior to this vitamin administration, ejaculates from males were collected to constitute the control (K), while the experimental ejaculates (D) were recollected from the boars after vitamin C supply. The present research has revealed an increased semen volume as well as a growth of total ejaculate sperm count under study and their concentration with concurrent elevation of percentage of progressively motile sperm cell, insemination dose number and spermatozoon count per dose. The rising dose of vitamin C administered to boars implied some changes in the aforementioned parameters. Alkaline phosphatase activity elevated by vitamin C supply has improved the percentage of progressive motility spermatozoa. Besides, vitamin C increased pH value in boar semen
