Abstract

BACKGROUND: This study was conducted to evaluate the effect of MELATONIN on semen quality and quantity changes and increase of reproductive efficiency in LORI-BAKHTIARI RAM in the non-reproductive season.OBJECTIVES: The purpose of this study was to investigate the effect of MELATONIN on testicular size and semen qualitative and quantitative changes in the non-breeding season is LORI-BAKHTIARI RAMs.METHODS: This study was designed to evaluate the effects of MELATONIN on the quantity and quality of semen and TESTICULAR DIAMETER in 8 Lori- Bakhtiari rams (4 control rams and 4 treatment rams) for 10 weeks during spring 2013. Each ram in the treatment group was received three tablets of 18 mg implantable MELATONIN subcutaneously at the base of ear after 5 weeks from the start of the trial.RESULTS: Semen parameters and TESTICULAR DIAMETER measurements were evaluated on a weekly basis. No significant differences were observed between 2 groups before MELATONIN implanting. A significant difference was observed after MELATONIN implanting between 2 groups in the mean of TESTICULAR DIAMETER (treatment: 33.5±0.25 and control: 30.67±0.07 cm), in semen volume (treatment: 1.34±0.03 and control: 0.87±0.04 ml) and in sperm concentration (treatment: 1.76±0.05 and control: 1.37±0.04 109/ml) (p<0.05). However, other parameters including average of lives sperm percentage, total sperm motility, sperm progressive movement and percentage of abnormal sperm were not significant (p>0.05).CONCLUSIONS: The results of this experiment showed that the use of MELATONIN in the non-reproductive season resulted in increase of testicular size, semen volume and sperm concentration in LORI-BAKHTIARI RAM. However, the rest of the semen parameters have not been affected.
