Based on the results of this study, it can be concluded that for the use of this gene in the of milk production traits improvement, further research is needed.]]>

Using the 10% level of lemon pulp increased the feed conversion ratio in the periods of 21-49 and 1-49 days (P<0.05). Using the 10 % level of lemon pulp reduced the blood cholesterol concentration and increased the production of antibody against red blood cells of sheep at 35 and 42 days of age (P <0.05). Although hemoglobin level and hematocrit percentage were not influenced by experimental treatments (P>0.05), the amount of reactive substances was affected by thiobarbituric acid (P<0.05). In conclusion, the addition of lemon pulp at 7.5% of the diet without affecting the body weight can stimulate the immune system, which is a good alternative to poultry diets.]]>

Sperm motility, progresive motility and viability was higher significantly in the roosters receiving 1.5 or 3% diatary GP compared to the control (P<0.05), but sperm morphology and plasma membrane integrity were not affected by dietary treatment. Moereover, 3% GP supplementation effectively (P<0.05) increased serum testosterone levels and hatchability percentage compared to the control group. In conclusion, the diatary addition of antioxidant fibers such as GP may improve rooster semen quality and concequently hatchability in the broiler breeder stocks.]]>

Comparison of the parametric characters showed, mean values of characters TL1 (p<0.000), AnSL (p<0.005) and TL2 (p<0.005) were significantly different between the sexes. None of the four nonparametric characters showed significant differences between males and females (p>0.66). The ratio Tail length2 (TL2)to Tail length1 (TL1) and TL1 to Right bridge length (RBrL)are fast and simple grouping index to determine sex of the specimens. The most and the lowest number of specimens were collected in summer (n=52) and fall (n=6) respectively.]]>

Based on the data analysis, it has been shown that commercial ultra-Amax is a more effective and effective effect on Adult male Huso huso.

Therefore, according to the present results, applying of salinity stress on different treatments showed that the presence of arginine in the feed of carp fish may have a significant effect on their resistance and survival, so that for feed treatments with 1.5% and 2% of arginine within 72 hours did not show any casualties, therefore. Hence, according to the present results, use of 2% L-Arginine to increase weight of carp, recommended.]]>

Also, this treatment had the highest non-significant WBCs and monocyte counts (P>0.05). On the other hand, the highest values of IgM and lysozyme were showed in treatment 2g/kg acidifier supplementation (P>0.05). Based on obtained findings, it can be declared that acidifier supplementation can promote growth performance and improve some hematological and immune indices of common carp.]]>
