Abstract
Abstract Evaluation of probiotic is not summarized on growth but included the other aspects, such as blood parameters. In this study, effects of two bifidobacter, Bifidobacterium animalis and Bifidobacterium lactis with three concentrations of 1× 109 (T1), 2× 109 (T2) and 3× 109 (T2) ...

Abstract Evaluation of probiotic is not summarized on growth but included the other aspects, such as blood parameters. In this study, effects of two bifidobacter, Bifidobacterium animalis and Bifidobacterium lactis with three concentrations of 1× 109 (T1), 2× 109 (T2) and 3× 109 (T2) CFU/100g were studied on growth performance and hematological parameters of rainbow trout larvae with initial body weight of 0.538 ± 0.197 g. Thus 3 experimental treatments and a control, each with three replicates were prepared. Thirty rainbow trout larvae were stocked in each replicate. The larvae were fed 4 times a day according to 4-8% of body weight. After 8 weeks of feeding trail with supplemented diet with Bifidobacterium growth and hematological parameters were studied. The result of hemoglobin showed no significant difference between experimental treatments and the control (P>0.05). The use of Bifidobacter caused increase of red and white blood cells in T3 and T2 treatments (P0.05). The study of hematological parameters, final weight and specific growth rate in present study showed that the use of bifidobacter increased blood cell account and also the final weight growth in rainbow trout.

Abstract The Saffron plant (Crocus sativus), a native plant from Iran and especially of Khorasan region, has a specific place for people's diet. According to several studies about effects of Saffron and because there are no specific studies on the effects of Saffron on the development of Drosophila melanogaster as an animal model, this subject is being evaluated in the current study. A total of 5 pairs of 3-days-old wild Drosophila melanogaster were transferred to every culture plate containing different concentrations of Saffron in order to intercross and oviposition and were brought out after 8 hrs. sampling of larvae were performed in the seven steps at intervals of twelve hours and in each step, Morphometrical changes in the length and width of the larvae, were studied. The obtained data were evaluated statistically using SAS software, The variance between groups were evaluated by the test of One way ANOVA, and the mean of data were compared using Ttukey test with minimum significance level of p in high concentrations, has inverse effect on the biology of this insect.
