不同保存剂对燕麦干草营养成分和黄曲霉毒素B1含量的影响
Effect of different preservatives on nutrient composition and aflatoxin B1 content of oat hay
摘要
Abstract
The experiment was conducted to investigate the effects of different preservatives on the nutritional composition and aflatoxin B1 content of oat hay.Oat hay without any addition served as the control group(CK group).The J2,J4,B2,B4,T2,and T4 groups were supplemented with 0.2%curcumin,0.4%curcumin,0.2%calcium propionate,0.4%calcium propionate,2%potassium carbonate,and 4%potassium carbonate,respectively.Each group had three replicates.The nutritional components were measured at 30,60,and 90 days of storage,while the aflatoxin B1 content was determined at 90 days of storage.The results showed that compared with the control group,at 60 days of storage,the acid detergent fiber(ADF)content in the J2,J4,B2,and B4 groups extremely increased(P＜0.01),and the relative feed value(RFV)in all groups except T4 extremely decreased(P＜0.01).At 90 days of storage,the crude fat(EE)content in the J2 and T4 groups significantly decreased(P＜0.05),while the neutral detergent fiber(NDF)and ADF content in the J2,J4,B2,and B4 groups extremely decreased(P＜0.01),and the RFV extremely increased(P＜0.01).The aflatoxin B1 content in the T2 and T4 groups significantly decreased(P＜0.01).The study indicates that the addition of curcumin and calcium propionate can reduce the NDF and ADF content of hay and increase the RFV of hay after 90 days of storage,potassium carbonate showed a better effect in reducing the content of aflatoxin B1,making it suitable for application in hay processing.关键词
