Abstract:
Abstract: In this experiment 60 You Chicks were studied,30 of which injected with SS-IgY(Immunoglobin from Yolk of somatostatin) hypodermically in the neck and the rest without SS-IgY. The concentration of IGF- I, T3 andT4 in blood of You chicken were assayed with RIA and the results were as follows:compared with that in the control,the concentration of IGF- I and T4 in Blood in the experiment in creased significantly (p<0.O1),the change of the level of IGF- I in the experiment was similar to that of the efficiency of the growth promoting to You chicken with SS-IgY and there was a strong relation tween them(R=0.87). These results indicated that SS-IgY could enhance the IGF- I and T4 levels effectively as well as help the crease of the growth of You chicken.
