Effects Of Immunostimulant On The Growth Performance, Immunologic Function Of Cyprims Carpis, Litopenaeus Vannamei And Eriocheir Sinensis

The different levels of two kinds of prescription of immune on crap,L.vannamei anderiocheir sinensis were examined in terms of growth indices and immune index todetermine the suitable dose. Diets contained different levels of tai hao (0.00%,0.01%,0.05%,0.10%) and Qi Shensan (0.00%,0.30%,0.60%,0.90%). The results aresummarized as follows:1.The effect of tai hao on carp: the supplemented with0.05%peptides of experiment dietscan significantly improve the carp specific growth rate and weight gain, and dietscontained69.20%and11.06%of tai hao higher than those in the control group (30.89%and1.40%).The activity of SOD, LZM, CAT and AST reached maximal and significantlyhigher than control group in crab fed with0.05%(P<0.05). The conclusion is that thegrowth and immunity of crap increased along with the level of0.05%of tai hao in feed.2.The effect of tai hao on L.vannamei: the supplemented with0.10%peptides ofexperiment diets can significantly improve the carp specific growth rate and weight gain,and higher than those in the control group (63.22%).The activity of SOD, LZM, ACP andAKP reached maximal and significantly higher than control group in L.vannamei fed with0.10%(P<0.05). The conclusion is that the growth and immunity of L.vannameiincreased along with the level of0.10%of tai hao in feed.3.The effect of tai hao on eriocheir sinensis:to add0.10%relative weight gain rate and thespecific growth rate is highest in the group, significantly higher than the other threegroups(P <0.05);and diets contained88.32%and10.65%of tai hao higher than those inthe control group (35.90%and1.85%).The activity of CAT,and AST reached maximal andsignificantly higher than control group in eriocheir sinensis fed with0.10%(P<0.05). Theconclusion is that the growth and immunity of eriocheir sinensis increased along with thelevel of0.10%of tai hao in feed.4.The effect of Qi Shensan on carp: the supplemented with0.30%peptides of experimentdiets can significantly improve the carp specific growth rate and weight gain, and dietscontained77.97%and14.42%of Qi Shensan higher than those in the control group(35.28%and10.36%).The activity of LZM reached maximal and significantly higher thancontrol group in crap fed with0.30%(P<0.05). The activity of SOD reached maximal and significantly higherin crap fed with0.90%,But with0.30%added there was no significant5.difference between groups (P>0.05), in the case of cost savings that the activity of SODin addition amount of0.30%when the effect is best.The conclusion is that the growth andimmunity of crap increased along with the level of0.30%of Qi Shensan in feed.5.The effect of Qi Shensan on L.vannamei: the supplemented with0.30%peptides ofexperiment diets can significantly improve the carp specific growth rate and weight gain,and diets contained77.97%and14.42%of Qi Shensan higher than those in the controlgroup (35.28%and10.36%).The activity of SOD, LZM, ACP and AKP reached maximaland significantly higher than control group in L.vannamei fed with0.60%(P<0.05). Theconclusion is that the growth and immunity of L.vannamei increased along with the levelof0.60%of Qi Shensan in feed.6.The effect of Qi Shensan on eriocheir sinensis: the supplemented with0.60%peptides ofexperiment diets can significantly improve the carp specific growth rate and weight gain,and diets contained69.20%and11.06%of Qi Shensan higher than those in the controlgroup (30.89%and1.40%).The activity of SOD, LZM, CAT and AKP reached maximaland significantly higher than control group in eriocheir sinensis fed with0.60%(P<0.05).The conclusion is that the growth and immunity of eriocheir sinensis increased along withthe level of0.60%of Qi Shensan in feed.
