Effect of Vitamins C and E on Some Sperm Characteristics in Varamini Rooster in Cold Conditon

Abstract

A total of 36 breeder roosters were divided to 4 dietary treatments which were consisting of 3 pens with 3 birds per pen. Treatments were as follow: 1) Control diet without vitamins C and vitamin E, 2) Cdiet containing 1000 mg/kg vitamin C, 3) E-diet containing 1000 mg/kg vitamin E and 4) E+C diet containing vitamins C and E (1000mg/kg of each vitamin). Diets were fed to the roosters for a 28 d experimental period. Sperm collection was done by rubbing the belly method, and semen was diluted by of solution tris buffer and kept at 5°C temperature. Evaluated parameters were as follow: semen volume, sperm concentration, sperm motility, progressive sperm, live sperm, at 0, 6, 12, 24, 48, hours after sperm collection. Data analyzed by CRD and mean compared with Duncan multiple range test at the 5% level (P<0.05). Results indicated that Vitamin E resulted in increasing of semen volume and concentration, motility, live sperm, progressive sperm, at all evaluated times. Results of vitamin E+C diet were similar to vitamin E diets but despite of vitamin E this diet (C+E) is same as vitamin C diets, too. It seems that, in this study, dietary vitamin E can improve Varaminian rooster sperm characteristic rather than the other experimental groups in dirds. Therefore addition of vitamin E in the rooster diets in order to improve sperm characteristics, can be recommended.

Enhancement of sperm quality and fertility-related parameters in Hubbard grandparent rooster fed diets supplemented with soybean lecithin and vitamin E

“… Cerolini et al (2006) reported that the addition of 300 mg of vitamin E to the diet of Cobb broiler breeder roosters significantly increased sperm volume and concentration. Similar findings were reported by Darestani et al (2019) who added 1,000 mg of vitamin E to the Varamini roosters' diet. Our findings in this part of study agree with Attia and Kamel (2012) who investigated the impact of soybean lecithin on rabbit sperm quality, and they found higher semen volume and sperm concentration in the diet supplemented with 1 and 1.5% soybean lecithin.…”
