Abstract
The study aimed to investigate the effect of asparagus extract on quality semen of Arabian rams at different storage times at a temperature of 4 degrees Celsius. Sperm collection was performed from 10 Arab rams with an average age of 2.5 years per week (once a week) for six weeks. After adding 0, 1.5, ...

The study aimed to investigate the effect of asparagus extract on quality semen of Arabian rams at different storage times at a temperature of 4 degrees Celsius. Sperm collection was performed from 10 Arab rams with an average age of 2.5 years per week (once a week) for six weeks. After adding 0, 1.5, 3 and 4.5% asparagus extract to the semen diluent, sperm quality parameters were evaluated at 0, 24, 48, and 72 hours after storage in liquid condition. At zero hour, sperm viability in diluent had 3% asparagus extract was higher than diluent containing 0 and 4.5% extract (P<0.05). After 24 hours of semen storage, the parameters of total motility, progressive motility, plasma membrane integrity and viability were higher in sperm diluent containing 1.5 and 3% of the extract (P<0.05). Qualitative parameters of sperm in 48 hours after sperm collection and storage in diluent contain 3% of extract had significant and better performance (P<0.05). The highest rate of plasma membrane integrity, progressive motility and total sperm motility was observed in diluent containing 3% extract in 72 hours after sperm storage (P<0.05). According to the results of this study, the use of asparagus extract in the diluent at the rate of 3% improves the sperm quality of Arabian rams after cooling conditions.

Abstract
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 ...

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.
