Comparing the Effect of Oral Supplementation of Vitamin E, Injective Vitamin E and Selenium or Both during Late Pregnancy on Production and Reproductive Performance and Immune Function of Dairy Cows and Calves

Abstract

The object of this study was to determine the effect of prepartum supplementation of vitamin E with or without injective vitamin E and selenium (Se) on productive and reproductive performances and immune function in dairy cows. Sixty multiparous Holstein dairy cows were divided randomly into three groups at the end of gestation. Cows in each group received one of three treatments: (1) a single intramuscular (im) injection of vit. E + selenium 3 weeks prepartum; (2) daily supplementation of oral vit. E given from 3 weeks prepartum to parturition; (3) injective vit. E + Se with daily supplementation of oral vit. E. Blood samples were collected from cows at calving and from calves at 0 and 7 days of age. Concentration of IgG in serum of cows and calves as well as in colostrum was determined. No significant differences among treatments occurred in the concentrations of IgG, animal, and calf production and reproduction performance. Due to the lack of significant difference between injection and oral supplementation, it is recommended to replace the injection with oral supplementation.

Effect of Vitamin E Supplementation on Milk Yield, Milk Fatty Acids Profile and Economical Efficiency in Buffalo Cows

“…The increase in milk yield was assumed to be due to protection of mammary tissue from free radicals. The present results agreed with the results of Anwar et al, (2014), Kafilzadeh, et al, (2014), Salama et al, (2015) and Maurya et al, (2016), while the opposite trend was observed by Chatterjee (2002).…”

Physiological changes in the adenosine deaminase activity, antioxidant and inflammatory parameters in pregnant cows and at post‐partum

“…A dysregulation on the activation of these cells may lead to abortion, as well as diseases (Chatterjee, Chiasson, Bounds, & Mitchell, ). Several diseases and metabolic problems occur during the gestational period, mainly during or after calving (Persson, ), as this period is linked to immunosuppression (Kafilzadeh et al., ). Several factors are responsible for immunosuppression during gestation, such as endocrine alterations and decreased intake of nutrients involved in the antioxidant activity and biological functions of the animal (Persson, ; Kafilzadeh et al., ).…”

<b>Efeitos da administração de um suplemento de microminerais injetável contendo cobre, manganês, selênio e zinco sobre a saúde uterina de vacas leiteiras</b>

“…Não foi encontrado diferença estatisca entre os grupos estudados nas duas avaliações (P= 0,7484 e P = 0,8180 respectivamente) na quantidade de animais prenhez. Kafilzadeh et al (2014) comparando o efeito de uma suplementação oral de vitamina E, com um suplemento injetável contento selênio e vitamina E, não encontraram diferença estatística na avliação de prenhez. Esse resultado foi semelhante ao encontrado nesse estudo.…”
