Summary
The present study investigated the effect of singular or combined administration of Pediococcus acidilactici and Raffinos on growth performance and some biological characteristics of eggs and spermatogonal parameters of gold fish (Carassius auratus). 180 gold fish, with average weight of 26.3±0.18 after two weeks of adaptation to laboratory condition In 4 treatments and each treatment with 3 replicates including: commercial diet (control group), commercial diet supplemented with 0/9×107 CFU/g P. acidilactici, 10 g kg-1 Raffinos or simultaneously supplemented with 0/9×107 CFU/g P. acidilactici and 10 g kg-1 Raffinos accidentally divided. The trial lasted 60 days, and fish sampling was performed to evaluate the growth indices and quality indices of egg and sperm at the end of the experiment. The results of analysis of growth indices showed that the rate of body weight gain, weight gain and specific growth rate in synbiotic treatment had a significant difference with the control group (P<0.05). However, there was no significant difference in the level of feed conversion ratio, condition factor and survival index in different treatments (P> 0.05) Also, the analysis of oocyte and sperm quality indices showed that there was no significant difference in the level of sperm density, spermatocrit and pH of seminal fluid in different treatments (P< 0.05) However, sperm motility duration, oocyte diameter and yolk space were significantly different in the control group (P <0.05). |
