Effects of different proportions of 'Zhang Za Gu' on semen quality and serum biochemical indexes in male breeder rabbits.

The study aimed to investigate the effects of 'Zhang Za Gu' on the semen quality and serum biochemical indexes in male breeder rabbits. Thirty-six healthy adult Iraqi male rabbits with good sexual desire were randomly divided into six groups, with six replicates in each group and one breeder rabbits in each replicate. Rabbits in each group were fed diets containing 0, 5%, 10%, 15%, 20%, and 25% 'Zhang Za Gu', respectively. The pretrial period was seven days, and the pretrial period was 90 days. The results showed that, compared to day 30, sperm motility and sperm density of the experimental groups increased on the 60th day and the 90 th day ( P<0.05), while semen volume and sperm abnormality rate showed no significant changes ( P>0.05). Different levels of 'Zhang Za Gu' had no significant impact on the serum biochemical indices of male breeder rabbits ( P>0.05). The study indicates that considering factors such as feed cost and semen quality, the optimal effect is observed when 'Zhang Za Gu' appending proportion is 10%. [ABSTRACT FROM AUTHOR]
