Taking grass carps with the initial weight of about 20g as the research object,the basic feeds of grass carps were added with0.0%,0.1%,0.3%,0.6%,0.8%,and 1% of nano-sustained release sodium butyrate to prepare 6 types of experimental feeds with equal nitrogen and energy.The effects of different concentrations of nano-sustained release sodium butyrate were surveyed on growth and intestinal cell proliferation of grass carps.The experiment was carried out in cages with 50 carps per cage,and each treatment was repeated 3 times for60 days.Experimental results indicated that the addition of nano-sustained release sodium butyrate significantly promoted the growth of grass carps and significantly increased the ratio of intestinal villus to crypt depth.When the addition of nano-sustained release sodium butyrate was0.6%,the weight increase rate,specific growth rate,fullness and intestinal villus height of grass carps were the highest,which was significantly higher than that of the control group(P < 0.05).The study results indicated that addition of appropriate amount of nano-sustained release sodium butyrate can promote the growth of grass carps through increasing the intestinal villus height,and the suitable addition dosage was0.6%.
