Abstract

Abstract: Background: Unreasonable use of antibiotics in animals is a major concern and will remain so, thus affecting people's health. However, the application of plant extracts can better solve this problem. Objectives: The purpose of this study was to study the effect of Moringa leaf flavonoids on the production performance, immunity, and rumen fermentation of dairy cows. Methods: Nine Holstein multiparous cows (average weight: 550 kg; days of lactation: 150 ± 6 days) were used in the experiment, using a 3 × 3 Latin square design. Cows were divided into three groups, each of which was supplemented with 0, 50, or 100 mg/body weight (BW) Moringa oleifera leaf flavonoids. Each experimental period consisted of three periods of 21 days, and the prefeeding period lasted 15 days. Results: Our results indicated that supplementation with Moringa leaf flavonoids increased the protein content and decreased the number of somatic cells in milk; had little effect on the biochemical indices of blood, the rumen fermentation, and serum biochemical indicators; and improved the activity of antioxidant enzymes, the antioxidant capacity, and immunity. Conclusions: Addition of 50 mg/BW Moringa leaf flavonoids to cow enhanced the antioxidant and immunity capacity in dairy cows but did not affect physiological levels of common biochemical parameters in blood or fermentation parameters in rumen. Abstract : In this study, we found that adding 50mg/BW moringa leaf flavonoids increased the protein content in milk, reduced the number of somatic cells, and had no effect on milk production, milk fat, total solids, and other indicators. At the same time, it improves the antioxidant capacity and immunity of dairy cows and does not affect blood physiological and biochemical indicators and rumen fermentation parameters.
