This research was carried out to evaluate the effect of sunflower seed meal fermented with Aspergillus niger and Saccharomyces cerevisiae on performance, nutrient digestibility, immune response, some blood parameters in 200 male Ross 308 broiler chicks in a completely randomized design. with five treatments. Experimental treatments were: 1- Diet containing sunflower seed meal fermented by Aspergillus niger 2- Diet containing sunflower seed meal fermented by Saccharomyces cerevisiae 3- Diet containing sunflower seed meal fermented by both Aspergillus niger and Aspergillus niger 4- Diet containing sunflower seed meal without processing 5-Control diet based on corn and soybean meal. Feed intake in control and treatment 1 were higher than the other treatments in starter and finisher periods of the experiment (P<0.05). Daily Feed intake in control group was higher than the other treatments in whole period of the experiment (P<0.05). Daily weight gain in control and treatment 1 were higher than the other group in starter and grower periods of the experiment (P<0.05). Feed conversion ratio in treatment 1 was better in finisher phase. In whole period of the experiment, feed conversion ratio in control and treatment 1 was better than the other treatments (P<0.05). Dry matter, crude protein, crude fat digestibility in the control group was higher than the other treatments (P<0.05). In conclusion, inclusion of sunflower seed meal fermented with Aspergillus niger, in broiler diet showed similar feed conversion ratio in compared to control group in whole period of the experiment and also lowered abdominal fat percentage.

To investigate the effect of fatty liver on insulin resistance in the liver of laying hens, an experiment using 80 laying hens of commercial line strains (w-36) after peak production (age 43 weeks) for eight weeks were performedin a completely randomized design with two treatments. The experimental treatments included control group (no injection) and the estradiol group (injection of two mg estradiol benzoate per kg body weight). In order to induce fatty liver disease, the injection of 17-beta estradiol started from the third week of experiment (age 46), and was performed three times a week for 21 days. Blood samples were taken to evaluate the concentration of triglycerides, cholesterol and liver enzymes (aspartate transaminase (AST), alanin transaminase (ALT) and alkaline phosphatase (ALP) at the end of the experiment using 20 hens from each treatment. At the end of experiment, five hens of each treatment were selected and sacrificed, then 50 g of liver tissue was removed to study gene expression of insulin receptor (InR), glucose transporter1 (Glut1), sterol regulatory element binding protein (SREBP1), Ribosomal S6 kinase1 (S6K1), Target of Rapamycin (TOR) and Forkhead box protein O1 (FOXO1). The results showed that the injection of estradiol induced fatty liver and increased plasma concentrations of cholesterol and triglyceride as well as activity of AST, ALT and ALP. In hens with fatty liver, expression of FOXO1 (4.1-fold), TOR (3.9-fold), S6K1 (3.3-fold) genes increased, and conversely, expression of InR (4.6-fold), Glut1 (7.5-fold) decreased. In conclusion results of the present study showed that the fatty liver induction in laying hens increased expression of insulin resistance-related genes.

The occurrence and spread of inflammation can affect the quantity and quality of eggs in laying hens. Therefore, the aim of this study was to evaluate the effect of soy Gensitein (GEN)on systemic inflammatory status and performances of laying hens post-peak. The research was performed in a completely randomized design, during a period of about 8 weeks, using 80 laying hens of High Line W-36 strains (older than 43 weeks). Experimental treatments were control group (basal diet) and genistein group (basal diet+ 20mg GEN/kg of diet). At the end of experiment, five hens from each treatment were laughter and 50 g of liver sample were taken for gene expression of IL-1, IL-2, TNF-α, COX-1 and COX-2. Results showed that soy GEN decreased gene expression of IL-1 (245 fold), IL-2 (3.53 fold), IL-6 (2.68 fold), TNF-α (4.83 fold), COX-1 (3.92 fold) and COX-2 (1.73 fold) compared to the control group. Laying hens fed GEN diets had higher feed intake and better conversion ratio and had higher egg production rates than the control group.The results of this study showed that soy GEN could reduce inflammation in the liver of laying hens post-peak and improve production performances.

Effect of Basil powder and extract on yield and carcass characteristics, relative expression of heat shock protein gene (HSP70) and some blood parameters of broiler chickens under heat stress using 160 Ross 308 one-day-old broiler chicks in a completely randomized design with 5 treatments and 4 replications (8 chickens per replication), was evaluated for 42 days. Treatments included: 1- Basic diet (control), 2- Basic diet+ Vitamin C (250 mg per kg of grain), 3- Basic diet + 25 mg of Basil powder (per kg of grain), 4- Basic diet +50 mg of Basil powder (per kg of grain), 5- The use of Basil extract (1 ml/liter water). Feed intake, body weight gain, feed conversion ratio, carcass characteristics, blood parameters and relative expression of HSP70 gene in blood were measured. The effects of treatments on blood parameters and carcass characteristics were not significant. Relative expression of the HSP70 gene in the blood was significantly reduced in all treatments compared to the control (P<0.05). Based on the results, basil powder and extract reduce the negative effects of heat stress in broilers, so their use in broiler diets is recommended to prevent heat stress.
