Influence of pasture feeding on milk and meat products in terms of human health and product quality

Abstract

Cows are fed either indoors on a diet of mixed ration or in areas with temperate climates, such as Ireland and New Zealand, the feeding regime of dairy and beef herds is almost entirely pasture-based. Animal feeding regimes and herd management practices are linked to differences in organoleptic and nutritional quality attributes of milk, dairy and meat/beef products, with pasture-based feeding systems being associated with superior quality produce. Consumers generally perceive that milk and meat products produced from outdoor grazing pastures are “healthier” than produce derived from indoor feeding systems, based on animals fed typical indoor rations and concentrates. However, while research has demonstrated differences in milk and meat quality, especially in terms of fatty acids, based on different feeding systems, data are limited on the impact of dairy and meat products produced from different feeding systems on human health.
