“…In this study, it was determined that in both group Vitamin E + selenium administered and in vitamin E administered group sperm mass activity increased, this increase was found to be statistically significant ( p < .05) at 24th and 48th hr. Similar to the findings of this study, Mahmoud et al () have expressed that the sperm mass activity increased ( p < .01) in the rams administrated with Vitamin E and selenium compared with the control groups.…”

“…mass activity increased, this increase was found to be statistically significant (p < .05) at 24th and 48th hr. Similar to the findings of this study, Mahmoud et al (2013) have expressed that the sperm mass activity increased (p < .01) in the rams administrated with Vitamin E and selenium compared with the control groups. Liu et al (2015) found that an increase in the progressive sperm motility was induced by the addition of 400 mg/kg vitamin E to the rations of bulls.…”

“…Shi, Zhang, et al () stated that they added short‐term selenium to the ration of the monks and increased the semen volume. Similarly, Mahmoud, Abdel‐Raheem, and Hussein () found that the ejaculate volume was increased in the rams administered by vitamin E and selenium. Different results in semen volume may vary depending on the difference in sperm collection method, feeding of animals and frequency of semen collection.…”

“…Shi, Zhang, et al () reported that sperm concentration in male goats increased by adding selenium to their rations in a short‐term. Mahmoud et al () reported that sperm concentration in rams administered with vitamin E and selenium increased compared to control groups. Vitamin E helps maintaining homeostasis in cells.…”

“…Some researchers have found that male goats with selenium added rations have a significantly lower percentage of abnormal sperm (Shi, Zhang, et al, ). Mahmoud et al () reported that the abnormal spermatozoan rate decreased in the rams administered vitamin E and selenium. Safa et al () found that the total abnormal sperm rate decreased when roosters alone applied vitamine E (5 or 10.1 g/ml) and combined vitamin E (5 or 10 g/ml) and nano‐selenium (1% or 2%).…”

The effects of vitamin E and vitamin E‐selenium combination on seminal plasma arginase activity and nitric oxide level and some spermatological properties in rams were investigated in this study. For control group, animals were injected intramuscularly with physiological saline. For vitamin E group, rams were injected intramuscularly with 300 mg/ram vitamin E. For vitamin E + selenium group, animals were injected intramuscularly with 5 ml/ram vitamin E + selenium. The semen was collected by artificial vagina at 1st, 4th, 24th, 48th and 72nd hr after administration in each group. Significant decreases in seminal plasma arginase activity (at 1st, 24th and 48th hr), nitric oxide level (at 72nd hr) and abnormal sperm rate (at 1st, 24th and 72nd hr), and significant increases in semen volume (at 24th hr), semen mass activity (at 24th and 48th hr), sperm motility (at 24th, 48th and 72nd hr) and concentration (at 1st hr) were observed in vitamin E group compared with control group. Similarly, significant increase in semen volume (at 1st, 24th and 48th hr), mass activity, (at 48th hr), motility (at 48th and 72nd hr) and concentration (at 4th, 24th and 48th hr), and significant decrements in abnormal sperm rate (at 1st, 24th, 48th and 72nd hr), seminal plasma nitric oxide level (at 1st, 4th, 24th and 48th hr) and semen pH (at 24th and 48th hr) were detected in vitamin E + selenium group in comparison to the control group. As a result, it is suggested that vitamin E and/or vitamin E + selenium applications may improve reproductive performance.

Subfertility is a multifactorial disorder that affects the rabbit production industry. However, subfertility may be treated by using a simple intervention such as vitamin supplementation. Vitamin E and selenium (Se) are potent antioxidants that protect the male reproductive system. The aim of this study is to determine the effects of vitamin E and Se on testicular size, semen quality and freezability, antioxidant activity, testosterone levels, and fertility in subfertile rabbits. Twenty-one New Zealand rabbits were classified as subfertile rabbits based on their semen characteristics and fertility records. The rabbits were randomly allocated into 3 equal groups (G1: control; G2: injected with Vit E 100 IU/head + Se 0.1 mg/kg b.w.; G3: injected with Vit E 200 IU/head + Se 0.2 mg/kg b.w. once weekly for 8 weeks).Once weekly for 8 W, blood samples were collected to measure serum testosterone level and total antioxidant capacity (TAC), and semen samples were collected by artificial vagina to assess the quality of fresh and frozen semen. At the 8th week of the study, 150 multiparous does were artificially inseminated with fresh semen to assess the fertility of rabbits after treatment; 50 does for each group. At the end of the study, rabbits were slaughtered to assess testicular morphometry. Fresh and post-thaw semen quality parameters were significantly (p < 0.05) higher in G3in comparison with G2and G1, respectively. Also, testosterone level was significantly (p < 0.05) increased at the 2nd week in G3in comparison with other groups. Conception and kindling rates were significantly (p < 0.05) higher in does which were inseminated with semen fromG3. In conclusion, injection of vitamin E and selenium at a higher dose (G3) improved the testicular morphology, quality of fresh and post-thaw semen, and most importantly, the fertility of subfertile rabbits.
