菜籽粕的营养价值及其在家禽生产中的应用进展OA

China has a large-scale poultry industry with substantial feed demand,and feed protein is mainly supplied by soybean meal.However,the shortage of domestic soybean resources and the high price of soybean meal have increased production costs and hindered the healthy development of the poultry industry.Rapeseed meal,a by-product of obtained after oil extraction from rapeseed,is rich in protein with a relatively balanced amino acid profile,and contains abundant mineral elements,making it a promising alternative to soybean meal.Nevertheless,rapeseed meal contains antinutritional factors such as glucosinolates,tannins,phytic acid,and sinapine,which reduce feed protein utilization efficiency in poultry and lead to impaired growth performance and reproductive capacity,thereby limiting the application of rapeseed meal in poultry production.To improve the utilization efficiency of rapeseed meal,antinutritional factors of rapeseed meal can be eliminated through physical,chemical,and microbial fermentation methods.This review summarizes the nutritional value of rapeseed meal,types of antinutritional factors,methods for elimination of antinutritional factors,and its application in poultry production,with the aim of the rational utilization of rapeseed meal,reduction of feed costs,and promotion of application of rapeseed meal in poultry production.
