Carbohydrate and amino acid metabolism and oxidative status in Holstein heifers precision-fed diets with different forage to concentrate ratios

Animal, 2020
Previous work led to the proposal that the precision feeding of a high-concentrate diet may represent a potential method with which to enhance feed efficiency (FE) when rearing dairy heifers. However, the physiological and metabolic mechanisms underlying

Impacts of Highland cattle browsing on encroaching Alnus viridis shrubs

Restoration Ecology, EarlyView.
Abstract Introduction In several European mountain chains, the expansion of the tall shrub Alnus viridis into mountain pastures has altered vegetation structure and composition, reduced plant species diversity, and diminished forage quality. Recent woody encroachment research has explored the use of robust livestock breeds, such as Highland cattle (Bos
