Abstract:
The use of the plant Tribulus Terrestris can improve semen quality in some mammals and birds. However, little information is available about adult male lambs. The purpose of this experiment was to investigate the effect of different levels of Tribulus terrestris on quantitative and qualitative characteristics of sperm of mature male lambs. In this study, 18 lambs of the arabi lambes age 3 monthes and average body weight 16.14±2 were divided into three groups of six in a completely randomized design, and received different levels of Tribulus terrestris including three groups: 1) without Tribulus terrestris (control), 2) 15 g/kg DM Tribulus terrestris and 3) 30 g/kg DM Tribulus terrestris for 5 months. The spermatogenesis was carried out by the electrocautery device two times a week from lambs after feeding Tribulus Terrestris. Quantitative and qualitative semen parameters including seminal volume and pH, sperm concentration, motility, survival and morphological abnormalities of sperms were evaluated. Results showed, the lowest semen volume was in the control group (p < 0.05). The highest concentration, motility and survival of sperm were from 15 g of Tribulus terrestris (p < 0.05). The level of 30 g of Tribulus terrestris showed the highest morphological abnormalities of sperm (p < 0.05). Mean pH was not affected by experimental treatments (p < 0.05). In conclusion, considering to all the measured parameters, adding 15 g of Tribulus terrestris per kilogram dry matter to the diet improved the quantitative and qualitative characteristics of sperm in the freshly mature arabi lambs.
