The Application of Indicator Methods in Determining the Nutrients Digestibility in Housed and Grazing Livestock
摘要
Abstract
The digestibility of nutrients in feed is the foundation for evaluating the nutritional value of feed.Determining the digestibility of nutrients is crucial for optimizing feed formulas and evaluating the nutritional value of feed.There are two main methods for determining digestibility:the total fecal collection method and the indicator method.Commonly used external indicators are chromium oxide(Cr2O3)and titanium dioxide(TiO2);commonly used internal indicators include acid-insoluble ash(AIA),acid-detergent lignin(ADL),and dual indicators(ADL+AIA).The indicator method can reduce the workload of the total fecal collection method and can be used for digestibility determination in group animals under production conditions,reducing stress on animals and overcoming the disadvantage of the total fecal collection method being unusable during grazing.This article comprehensively reviews the application effects of the indicator method in housed poultry and grazing livestock,aiming to provide theoretical support and guidance for more accurately determining the digestibility of nutrients in feed in actual production.关键词
