Abstract

The invention relates to a method for fast evaluating corn poultry metabolic energy through physicochemical indexes. The method comprises determining neutral washing fibers (NDF), volume-weight volume (V) and an actually measured metabolic energy value of a plurality of corn samples, conducting regression analysis on determined results and creating a mathematical model for fast evaluating the poultry metabolic energy value. The mathematical model constructed by the method can accurately forecast the corn poultry metabolic energy, and the forecasted corn poultry metabolic energy value can better guarantee accuracy of poultry feed cooperation and exertion of production performance compared with data in a feed composition and trophic value table.

Description

(1) Technical field

[0001] The invention relates to a method for quickly assessing the metabolizable energy of poultry by using the physical and chemical indicators of corn, and belongs to the technical field of feed. (2) Background technology

[0002] Corn as an energy feed plays an important role in livestock and poultry farming. However, in the process of poultry feed preparation, the metabolizable energy of corn, as the main index to measure its feeding value, is basically unable to be measured except for special research due to many reasons such as the long time required for the measurement and the high requirements for instruments. Formula design was carried out according to the calibrated metabolizable energy value in the feed ingredient database. The metabolizable energy of corn is significantly related to its variety, planting area, processing method, etc., and has a large range of variation. During production, formula design is based on fixed values ​​in the datab...
