Abstract
Effect of Vitamin E and Selenium Injections on the Testes and Accessory Sex Glands of Barki Rams During Non-Breeding Season
Highlights
Vitamin E and selenium are essential nutrients in sheep and cow reproduction through indispensable for many biological processes as semen quality and spermatogenesis ( Jerry, 1996; Marin- Guzman et al, 1997; Yousef et al, 2003; Koyuncu and Yerlikaya, 2007)
Selenium is an essential dietary trace element required for biosynthesis of testosterone to maintain male fertility (Brown and Arthur, 2001)
The reproductive efficiency of rams can be improved with vitamin E and selenium in agreement with (Ali et al, 2009; Balicka-Ramsisz et al, 2006; Kolodztiej and Jacyno, 2005; Yousef et al, 2003; Mahmoud et al, 2013)
Summary
Vitamin E and selenium are essential nutrients in sheep and cow reproduction through indispensable for many biological processes as semen quality and spermatogenesis ( Jerry, 1996; Marin- Guzman et al, 1997; Yousef et al, 2003; Koyuncu and Yerlikaya, 2007). Selenium is an essential dietary trace element required for biosynthesis of testosterone to maintain male fertility (Brown and Arthur, 2001). Both testis and epididymis require exogenous supplied selenium in order to synthesize a variety of known selenoproteins which had role in spermiogenesis and post testicular sperm maturation (Ali et al, 2009). Ultrasound scanning was suitable for examination of testes and epididymis of rams, so as to interpretation of uncertain clinical findings and
