The dietary neutral detergent fiber for fattening crossbred cattle

Tóm tắt

This study aimed to find out the appropriate neutral detergent fiber (NDF) levels in the beef cattle diets for improving the fodder utilizations and profitability. The structural change of NDF in plants is influenced by their varieties, ages, parts and the harvested time, which affects the dry matter and nutrient digestibility in ruminants. The changing of NDF structures of the roughages affected the dry matter (DM) and other nutrient digestibilities in ruminants. In in vitro experimental conditions showed that the soluble carbohydrate or nitrogen free extraction content of roughages had more affection on gas and CH4 production compared to the NDF one. When increasing NDF contents in the incubated mixtures from 35 to 65%, this reduced gradually the organic matter (OM) digestibility (P
