蒸汽压片玉米在奶牛生产中的应用研究进展
Research Progress of Steam-flaked Corn and Its Application in Dairy Cattle Production
摘要
Abstract
Corn is one of the main sources of energy feed for dairy cow s,and steam-flaked technol-ogy is a mature processing w hich can change the physical form of raw materials and nutrients in the chemical structure through the mechanical wet and hot processing,and now it has been widely used in the processing of ruminant diets.The experimental studies have found that the steam pressure,temperature and processing time in the steam-flaked process will affect the bulk density and starch gelatinization of the flaked product,thus affecting the feeding effect.At the same time, corn treated with steam flaking can effectively improve the starch digestibility,accelerate the fermentation speed in the rumen,change the rumen fermentation mode,promote the synthesis of rumen microbial protein,and maintain the stability of the rumen pH and rumen environment. Many studies also showed that steam-flaked corn fed had no effect on feed intake of dairy cows, but increased its milk production and improved milk composition and milk performance.T he author reviewed the research progress of steam-flaked corn technology and its application in dairy cow production in order to provide references for the rational use of steam-flaked corn in our country.关键词
