          Mucuna prureins (L.) DC has an important substance named Levodopa (L-dopa) which has effects on the central nervous system and reproductive system. Therefore, supplementation of M. prureins in animal diets may result in an increase of semen quality. Thus, this experiment aimed to study the influence of the M. prureins dietary supplementation on the reproductive efficiency, through the promotion of semen quality, of boars. Six Large White and 3-crossbred (Large White x Landrace x Duroc) boars with an average age of 8 months were used in this experiment. Animals were divided into 3 groups according to the levels of M. prureins supplementation which are 0, 70 and 140 mg/kg BW. The semen was collected twice per week for 12 weeks. The results showed that M. prureins supplementation at the levels of 70 and 140 mg/kg BW significantly increased semen volume and sperm concentration and reduced abnormal sperm morphology (p<0.05). In addition, testosterone concentration in serum was measured. It was found that boars supplemented with M. prureins had higher serum testosterone content than that were not supplemented (p<0.05). Therefore, dietary supplementation of M. prureins can improve reproductive performance and testosterone level in boars.
