ABSTRACT
The objective of the study was the comparison the influence of the organic Se (Se-Yeast) + vitamin E and inorganic Se (Na2Se03) + vitamin E on reproductive performance of young boars. The studies were carried out on the 60 young boars of the 990 Polish synthetic line divided into 3 groups. During the test (from 70 to 180 days of age) the males received in 1 kg feed mixture: group I-0.2 mg inorganic Se + 30 mg vitamin E (standard mixture), groups II and III respectively: 0.2 and 0.4 mg organic Se + 60 mg vit. E. At 180 day of live selection index, testes volume, libido traits, semen characteristics were determined.The boars of groups II and III, in comparison with group I, reached little lower selection index, but characterized by higer (p≤0.01 and p≤0.05) testes volume, better libido, higer concentration and total number of spermatozoa in ejaculate, higer value of osmotic resistance test of acrosome membranes, lower precentage of spermatozoa with morphological defects and lower precentage of spermatozoa with morphological defects and lower aspartate aminotransferase activity.The were no statistically significant diferences between the males of the II and III groups with regard the analysed traits.
Key words: reproductive performance, selenium, vitamin E, young boars.
