| 14 | Assessment of dietary chaste tree (Vitex agnus-castus) fruit extract on growth performance, hemato-biochemical parameters, and mRNA levels of growth and appetite-related genes in goldfish (Carassius auratus)显示文摘In this study,the effect of oral administration of chaste tree fruit(CTF)extract was evaluated on growth performance,hematological indices,serum biochemical parameters,and the expression of growth and appetite-related genes in goldfish(Carassius auratus).The fry(N=300;2.40±0.12 g)were randomly dispersed into 12 aquaria and fed with different levels of CTF extract(0(control),0.5%,1.0%,and 1.5%)for 56 days.At the end of the trial,the highest body weight gain and the lowest feed conversion ratio were observed in the fish fed with 1.5%CTF extract(P<0.05).The group fed with CTF extract at 1.5%showed the highest levels of red blood cell,hemoglobin,hematocrit,and serum albumin(P<0.05),while no significant changes were observed for mean corpuscular volume,mean hemoglobin,and mean corpuscular hemoglobin concentration among all groups(P>0.05).The levels of aspartate transaminase and lactate dehydrogenase were decreased by increasing the supplementation levels of CTF extract and the lowest values were obtained in 1.5%CTF extract diet(P<0.05).The expression of growth hormone,insulin-like growth factor 1,and ghrelin genes was significantly up-regulated in the fish fed with 1.5%CTF extract compared to other treatments(P<0.05).Overall,the enrichment of goldfish diet with 1.5%CTF extract could interfere positively in the growth-related traits and hematological parameters. | Maedeh Rashmeei Seyed Pezhman Hosseini Shekarabi Mehdi Shamsaie Mehrgan Hamed Paknejad | 2022 | Aquaculture and Fisheries2022，7，3： | 0 |
