Abstract
The study was conducted to investigate the effects of supplementation with polyunsaturated fatty acids of different vegetable oils and L-carnitine on boar libido, semen characteristics, fatty acid composition of sperm and semen antioxidant properties. Thirty adult Pietrain x Duroc hybrid boars with similar age and body condition were randomly divided into 3 groups with 10 replicates and 1 pig in each replicate. The diet of group 1 was supplemented with 1.5% soybean oil; group 2 was supplemented with 1.5% soybean oil +200 mg/kg L-carnitine; group 3 was supplemented with 0. 3% of soybean oil +1.2% flax seed oil +200 mg/kg L-carni-tine. The feeding trial lasted for 16 weeks. The results showed that the semen volume and ejaculation duration of boars in group 3 were significantly higher than those in the other two groups (P <0. 01) , and the reaction time was significantly less than those in the other groups (P <0.01). The sperm motility of boars in group 3 was significantly higher than that of the boars in group 1 (P <0.01), and the sperm density was higher than that of the boars in group 1 (P >0.05). During 8 to 16 weeks, the sperm docosahexaenoic acid (DHA, n-3) content and activity of superoxide dismutase (SOD) of boars in group 3 were significantly higher than those in the other groups (P <0.05). The malondialdehyde ( MDA) content in semen of boars in group 1 was significantly higher than those in the other groups (P <0.01) during 8 to 16 weeks. The results suggest that dietary polyunsaturated fatty acids and L-camitine could enhance the boar libido, increase the sperm DHA content and semen antioxidant properties, and finally improve the boar semen production, sperm motility and sperm density.
