The present study evaluated the relationship between different dietary net energy (NE) levels and body condition score (BCS) on performance of dairy goats during the prepartum period. Forty-eight pregnant goats were kept in individual cages during the last 30 days before parturition. The experimental design was a completely randomized design with a 2 x 3 factorial arrangement of treatments (two BCS and three levels of NE in the diet). Goats were assigned to one of two groups, based on body […]

Selenium and vitamin E are important antioxidants for cells and tissues protection acting directly as a support for the udder health. This experiment was designed to evaluate the influence of prepartum selenium and vitamin E supplementation on milk somatic cell counts of Holstein cows. Eighty four animals were allocated into four treatments: control; supplementation with 5 mg Se/day; supplementation with 1000 UI vitamin E/day and supplementation with 5 mg Se/day + 1000 UI vitamin E/day. The supplementation started thirty days […]
