Effects of Dietary β-Carotene Supplementation on Vitamin A and β-Carotene Levels, Antioxidant Responses, and Milk Composition in Holstein Cows

2026-07-06

Abstract excerpt

<title>Abstract</title> <p>Background The transition from late gestation to early lactation challenges antioxidant defense in dairy cows. This study evaluated the effects of dietary β-carotene supplementation from 60 d prepartum to 90 d postpartum on milk composition, vitamin A and β-carotene status, antioxidant responses, and β-carotene oxygenase 1 (BCO1) and β-carotene oxygenase 2 (BCO2) mRNA abundance in Hols...
