Abstract

© 2018 Universidad Nacional Mayor de San Marcos. All rights reserved. Dairy cattle breeders (n=67) in the Mantaro valley (Junín, Peru) were surveyed in regard to feeding practices and the chemical-nutritional components of 68 feeds were analyzed for dry matter, raw protein, neutral detergent fiber, digestibility in vitro of dry matter, total digestible nutrients, metabolizable and digestible energy. Semintensive production situations predominate (78%) and legume-like grasses (94%), principally rye grass and clover (81 %), comprise the bulk of the diet. Grazing, supplemented with cut grass, grains and minerals gíven in the corrals, is the principal feeding strategy (77%), and maize is the most frequently used harvest residue (81 %). Nutritional values of cattle diet components from different parts of Mantaro valley are presented.
