The aim of this research is to investigate the effects of yeast-one of the single cell protein, grown on ethly alcohol medium-(eprin) which has a quality to be replaced instead of fish meal by protein quality and quantity. 75 parent mice (15 male and 60 female) were used in the experiment. The research was designed in four main groups and twelve replicates. The main groups received 0.0, 2.5, 5.0 and 7.5% eprin and 7.5, 5.0, 2.5 and 0.0% fish meal in their experimental diets respectively. Eprin 0.0%+7.5% fish meal receiving group was used as control and the other groups were compared with this group. The experiment designed according to "Randomized Blocks Design" and continued three generations of the mice. The experiment with first generation was continued 245 days, for second 169 days and for third 85 days. At the end of the feeding trial; blood samples of the mice were taken and erythrocyte, leucocyte, haemoglobin and heamatocrit values were analysed. In addition to these, histopathological examinations were carried out to dedect carcinogenic effects of eprin on various tissues and organs. We also calculated the effect of single cell protein on the weight gain, feed intake and fertility. According to the resullts obtained there is no statistically significant differences among the groups recevied either fish meal or eprin for all criteria investigated in this experiment (P>0.05). In contrast to these findings we also observed tail and leg deformations in some of the mice. But these observations are not related to feed. And it is quite appropriate to use eprin in a given level instead of fish meal. But we suggest that further investigation should be carried out in making clear these problem, genetically and terathogenicall.
