abstract

  • The aim of this work was to investigate the effects of Alumna pruriens seed meal (MSM) on sexual behavior, semen, and biochemical parameters in rabbit bucks. Twenty-four 12-week-old rabbit bucks weighing 1002 to 1156 g were randomly allocated to three experimental diets containing 0, L5, and 3% of MSM in a 3-month trial. Sexual behavior parameters such as mounting latency, mounting frequency, successful mounting frequency, intromission latency, and post ejaculatory interval were monitored at the end of the experiment by mating with receptive females. Thereafter, rabbits were weighed, stunned, and humanely sacrificed and testes, epididymis, and vas deferens were harvested for evaluation of organ weights and semen characteristics. Results indicate that supplementing rabbit diet with MSM induced a significant decrease (P < 0.05) in mounting latency (69.790) and intromission latency (19.790), while it significantly (P< 0.05) increased successful mounting frequency (60V) as well as relative weight of testis (33.3%) and vas deferens (54.590). There was a dose-dependent increase (P< 0.05) in sperm motility (35.790) and concentration (65.9%), serum albumin (19.1%) and protein concentration (9.9%), and a decrease in sperm morphological alterations (68.390), serum cholesterol (13.490), and urea (11.60%) in treatment groups where MSM was supplemented at 390 compared to controls. From the findings, it appears MSM is a potential enhancer of male reproductive performance that can be recommended to rabbit farmers for improving reproductive performance and quality of semen, hence a boon to reproduction and production in rabbit farming industry.
