Carotenoids content in forages: Variation during conservation

2005

Read source ↗ All evidence

Summary

This conference paper, published in the French ruminant research proceedings (Rencontres Recherches Ruminants), investigates how carotenoid content in forages varies according to the conservation method applied. It likely demonstrates that drying and storage processes result in significant degradation of carotenoids relative to fresh herbage, with implications for the nutritional value of feed reaching ruminant livestock. The findings are relevant to understanding how forage management affects the transfer of fat-soluble micronutrients through the feed chain to animal products.

UK applicability

The findings are broadly applicable to UK pasture-based livestock systems, where hay, silage, and haylage are widely used; UK producers and nutritionists should consider carotenoid losses during conservation when assessing the nutritional quality of conserved forages for dairy and beef cattle.

Key measures

Carotenoid concentration (mg/kg dry matter) in fresh and conserved forages; percentage losses during conservation methods

Outcomes reported

The study examined carotenoid concentrations in forages and how they change during conservation processes such as haymaking, ensiling, and dehydration. It likely reported quantitative losses of key carotenoids (e.g. beta-carotene, lutein, xanthophylls) relative to fresh forage values.
