Abstract:
The present study aimed at investigating the biological evaluation of a synbiotic fermented milk synergistic with some active ingredients of herbal hydrosols and honey on the sexual activity, semen characteristics and testosterone levels in Aradhi and Damascus goat`s bucks. A synbiotic syrup was prepared by mixing fermented cow`s milk containing some probiotic strains and natural antioxidants isolated from functional food and herbal hydrosols. Fifteen Damascus and Aradhi bucks were utilized in the experiment. Two bucks served as control (given no synbiotic), 7 bucks were designed to be orally given twenty ml of the mixture three times per week for 8 consecutive weeks (Low dose, Aradhi-Low = AL, Damascus-Low = DL) and 6 bucks were orally given 40 mL of the mixture (High dose, Aradhi-High = AH, Damascus-High = DH) by the same regime. Bucks were tested for the libido and semen ejaculates were collected once a week for testing the physical characteristics. A jugular blood sample was taken once a week in a non-heparinzed tube for the determinations of serum testosterone, alanine and aspartate amino transaminases (ALT and AST), urea and creatinine levels. Results indicated a significant enhancement of the libido due to the breed of the buck; Aradhi bucks exhibited less reaction time than Damascus bucks (p<0.01). The high dose of the mixture enhanced (p<0.01) the libido in both breeds. Testosterone levels were significantly (p<0.01) higher in Aradhi than Damascus bucks. There found significant increase in testosterone concentrations in treated Aradhi than in Damascus bucks. There were no differences between low and high mixture dose. Administration of the mixture resulted in an increased (p<0.01) ejaculate volume, gross and individual motility, sperm concentration, total motile sperm in the ejaculate than in control. Additionally, lower dead and abnormal sperm numbers were obtained with bucks given the mixture. Treatment slightly increased AST and urea but significantly increased ALT and creatinine in both breeds. In conclusion, giving goat bucks a mixture of a synbiotic functional syrup enhanced the metabolic activity resulting in improvements in their reproductive performance.
