摘要
饲用缓释包被尿素相比于普通尿素,能减缓尿素释放速率、提高氮利用率、更好的促进微生物蛋白的合成。目前,市场上缓释包被尿素产品种类较多,为评价缓释包被尿素饲料的产品质量,本文从颜色气味、粒度、包被材料、平均抗压碎力进行表型测定,从水分含量、尿素含量、氮含量进行理化成分的检测,选择1 h尿素释放率评估尿素缓释效果,旨在建立一套缓释包被尿素饲料评价体系,用于对饲用缓释包被尿素产品质量的评估。
Compared with urea,slow-release coated urea can reduce the release rate of urea,improve the utilization rate of nitrogen,and promote the synthesis of microbial protein.At present,there are many kinds of slow release coated urea products in the market,In order to evaluate the product quality of slow-release coated urea feed,we measured phenotypic indicators such as color,smell,particle size,coating material,and average crushing strength,and measured the physical and chemical components such as moisture content,urea content and nitrogen content,urea release rate at 1 h was selected to evaluate the slow release capacity of urea.Aimed to establish an evaluation system for slow-release coated urea feed to facilitate the quality evaluation of slow-release coated urea feed products.
