The aim of this study was to evaluate the effect of Tribulus terrestris powder on thyroid hormones (T3 &T4) and IGF-I concentrations in blood serum of Arabi male lambs. For this purpose, 18 Arabi male lambs with an average age of 3 months and average weight of 16.14 ± 2 kg were used in a completely randomized design with 3 treatments and 6 replications per treatment for 5 months. Experimental treatments included the zero (control), 15 and 30 gr/kg of Tribulus Terrestris powder in diet. The weights of lambs were measured monthly. At the age of 4-8 months, 5 consecutive samples were collected monthly to measure serum T3, T4 and IGF-I concentrations. The results showed thatTribulus terrestris powder had no significant effect on body weight. The concentrations of T3 and T4 were higher in lambs treated with Tribulus terrestris powder compared to control group (p<0.05). Concentrations of T3 at the age of 7 months and T4 at 8 months of age in lambs fed 30g/kg of Tribulus terrestris were significantly higher than control group (p<0.05). IGF-I concentration in lambs feed with 15g/kg of Tribulus terrestris at the age of 6 months was higher than control group (p<0.05). In general, the results of this study showed that feeding of 15 g/kg of Tribulus terrestris powder in Arabi male lamb diet by modulating thyroid hormones and IGF-1 and improving the reproductive system, prevents the reduction of sexual behavior and failure of reproductive activity.

The effects of two different extenders were investigated (Tris- egg yolk and Andromed extenders) on semen quality and sex ratio during the dilution and freezing process in Holstien bull by using the real-time qPCR technique. The experiment was conducted using four 4-years old Holstien bulls for a period of four weeks in a completely randomized design. The PLP and SRY genes were amplified to isolate the specific fragments of X- and Y- chromosome sequences, respectively. Using Andromed diluent in comparison with Tris- eggs yolk improved semen quality during freezing and thawing. Using Andromed extender significantly increased the PLP gene expression (1.43±0.16), (P= 0/01) and reduced SRY gene expression (0.64±0.11), (P= 0/009). Using Tris- egg yolk extender led to a significant reduced in expression of PLP gene (0.3±0.06), (P< 0/0001) and s increased SRY gene expression during freezing (1.19±0.05), (P= 0/001). Based on the results, sperm dilution with Andromed extender and frozen semen with Tris-egg yolk increase birth of female and male in dairy cow herd, respectively.

This study was carried out to examine the effect of supplementation of canola and fish oils (5% fish oil, 3% fish oil + 2% canola oil, 2% fish oil + 3% canola oil and 5% canola oil) and Satureja khuzistanica essential oils (SkEO) (0 and 400 mg/kg), into a basal diet on productive performance, meat cholesterol, lipid stability and certain blood lipid components in broiler chickens raised under normal and heat stress conditions during day 22 to 42 of age. The experiment was conducted in a 4×2×2 factorial expriment using 640 one-day-old Ross 308 chicks in a completely randomised blocks design with 5 replicates of 8 birds in each replication. Oil source significantly decreased FCR, serum LDL and cholesterol content in thigh and breast muscles at day 42 of age. Inclusion of 400 mg/kg SkEO in diet significantly increased daily weight gain and decreased cholesterol content and TBARS concentration in thigh and breast muscles in heat stressed chicks. Heat stress condition significantly decreased FCR and increased TBARS as well as cholesterol content in breast muscle and serum cholesterol concentration during day 22 to 42 of age. It was concluded that supplementation of 400 mg/kg SkEO and canola oil into diet could have a positive effect on productive performance and reduce the meat and serum cholesterol concentration in broiler chicken.

The objective of this experiment was to study the effects of dietary nano-selenium supplementation on the glutathione peroxidase activity and sperm quality and quantity parameters of Arabian rams. In this experiment, twelve Arabian rams with an average weight of 73±3 kg and age of two to four years were used. Animals were divided into three groups: the control group (without -nano Selenium) and two experimental groups that received 0.4 and 0.8 mg nano-selenium per kg dry matter, respectively. The results showed that significant increase in semen selenium concentration and semen glutathione peroxidase activity in group 0.8 mg nano-selenium compared with the control group (P<0.05), but there was no significant difference between 0.4 mg nano-selenium per kg supplementation and control group. The volume of ejaculate, sperm motility and viability increased in treatments compared with the control. Spermatozoa concentration was increased in group 0.4 mg nano-selenium per kg, but it was decreased in Group 0.8 mg nano-selenium per kg. The percentage of sperm abnormality significantly increased in control compared with experimental groups. According to the results of this research, supplementation of 0.4 mg Nano-selenium per kg dry matter in the diet, increased the glutathione peroxidase activity in semen and improve the quality and quantity characteristics of sperm.

The Effect of various amount of soybean lecithin replaced with egg yolk to protect the ram semen in times of one hour after semen collection, as well as 24 and 48 hours after the semen store at 5°C was evaluated. Semen was collected weekly for 8 weeks from 10 rams with 2-3 years old and average body weights of 64 kg. Semen samples were pooled and divided into 4 parts. Each part was diluted with one of the tris base extender containing 0.5, 1 and 1.5 percent of soybean lecithin and 14 percent of egg yolk. The motility, viability, morphological abnormalities and membrane integrity of spermatozoa and pH of semen were evaluated. The results showed that 1.5 percent of soybean lecithin improved the motility and viability of spermatozoa at the first time (P< 0.05). At the 48 hours after the semen store in 1 and 1.5 percent of soybean lecithin the sperm viability improved when compared with egg yolk treatment (P<0.05). Overall, soybean lecithin is the appropriate replacement with egg yolk and improved the semen quality in times of study. With regard to limitations of egg yolk using with animal source in ram extender, it was recommended to be using the soybean lecithin as the plant source.

This study was carried out to evaluate the effect of different levels of anise seed on the performance, immune system, antioxidant activity and blood estrogen level of broiler chicks. A total of 192 day -old Ross 308 broilers were trained for 42 days in a completely randomized design with four treatments, four replicates and 12 birds per each replicate. Treatments were included the levels of zero (control(, 0.3, 0.6 and 0.9 percent of anise seed in diet. SRBC was injected at day 28 and blood samples were collected from chickens at days 35 and 42 of rearing. Dietary anise supplementation had no positive effect on feed intake and weight gain of broilers. In starter period, the chicks fed by 0.3 percent of anise seed, had the least feed conversion ratio (P<0.05). However, anise seed levels had no positive effects on feed conversion ratio in grower and total rearing period. Anise seed caused the higher antibody titer against SRBC in day 35 of rearing (P<0.05). The cellular immunity did not improve by anise seed levels in broilers. The 0.3 percent of anise seed, caused the higher total antioxidant capacity of blood plasma than control chicks (P<0.05). The blood serum estrogen level was reduced in 0.3 and 0.6 percent, but increased in 0.9 percent of anise seed (P<0.05). Generally, however the anise seed dose not improves performance traits and cellular immunity of broilers, but increse the primary humeral immunity and total antioxidant capacity of chicken.

In order to evaluation the effect of Nigella Sativa supplementation on performance, immune response and some of blood parameters, a total of 192 one day old Ross 308 broilers were used in a completely randomize design with four treatments, four replicates and 12 observations in each replicate. Treatments included the increasing levels of zero (control), 0.4, 0.8 and 1.2 percent Nigella sativa. In grower and whole period of experiment, the weight of birds received 0.4 and 0.8 percent of Nigella sativa was higher than control group birds (P<0.05). The supplementation of Nigella sativa in diet has not effect on feed intake and feed conversion ratio in starter, grower and total rearing periods. The weights of bursa and thymus in birds received 0.4 and 0.8 percent of Nigella sativa werehigher than control group birds (P<0.05). The weight of liver in birds belong to 0.4 percent of Nigella sativawas higher than control group (P<0.05). Addition of Nigella sativa in dietreduced the glucose, triglyceride, cholesterol, LDL and increased the HDL in blood serum. The use of Nigella sativa in dietary of birds caused the higher total white blood cells and lower heterophil: lymphocyte ratio. The birds which received 0.4 and 0.8 percent of Nigella sativa had the higher total antioxidant capacity than control group in blood plasma. In conclusion, the use of Nigella sativa up to 0.8 percent in diet, in addition to improvement the performance, increased the immune system activity and total antioxidant capacity in Ross 308 broiler chickens.

Effect of levels of zinc supplementation on footpad lesions, reproductive and blood parameters of broiler breeders with 300 hens and 40 roosters of Ross 308 strain with four treatments, five replicates and 15 hens and two roosters in each for 12 weeks was evaluated in a completely randomized design. Dietary treatments were 80, 110, 140 and 170 mg zinc/kg diet. Increasing supplemental zinc level especial 170 mg/kg diet increased hatchability (P<0.05). Levels of 140 and 170 mg zinc/kg diet significantly improved footpad lesions (P<0.05). In the first phase of incubation, the lowest rate of mortality observed in 140mg zinc/kg diet (P<0.05). Also, number of large and small size follicles of broiler breeders increased at 170 mg zinc/kg diet (P<0.05). Blood parameters did not affect significantly. The results of this experiment showed that supplementation of broiler breeders diet with zinc at 140 and 170 mg/kg diet could improve hatchability and had desirable effect on footpad health.
