Prospective effect of vitamin E and selenium supplementation on colostrum quality in Beetal goats

Abstract

AbstractThis study was aimed to explore whether vitamin E (Vit-E) and selenium (Se) injections improve colostrum quality in goats. Twenty-four, healthy pregnant Beetal goats were randomly allocated into control (n = 12) and treated (n = 12) groups respectively. The injectable form of Vit-E 2.5 mg/kg BW and Se 2.2 mg/kg BW was administered fortnightly, while normal saline (0.9% NaCl) was used and served as a control group. Colostrum samples were collected immediately after parturition and subjected to biochemical analysis. Colostrum enzymatic and non-enzymatic antioxidants and total soluble proteins were investigated using a spectrophotometer. Antioxidants with enzymatic activities including superoxide dismutase (SOD) and peroxidases (POD) and ascorbic acid remained significantly higher in treated animals (P <0.05) in contrast to the control group. The Total antioxidant capacity (TAC) and total soluble proteins (TSP) levels were noted higher (P<0.05), however; the level of MDA existed significantly lesser in the treated group (P <0.05) in comparison with the control group. Overall, results showed that parental exposure to antioxidants (Vit-E and Se) improved antioxidant status in colostrum and upgrade its quality.
