添加丙酸钙和尿素对玉米秸秆黄储发酵品质的影响
Effects of adding calcium propionate and urea on fermentation quality of yellow storage of corn stalk
摘要
Abstract
Five treatments of adding different concentration of calcium propionate (CP) and urea (U)(4％ urea,0.2％ CP and 0.4％ CP,4％ urea + 0.2％ CP,4％ urea + 0.4％ CP) and control treatment (CK) were set up to evaluate the effects of adding calcium propionate and urea on fermentation quality of yellow corn stalk silage.The silos were opened after 90 days of ensiling and the fermentation quality was analyzed.The results showed that there was no significant difference in dry matter among all treatments.Compared with the CK,crude protein of all group tended to increase,neutral detergent fiber and acid detergent fiber tended to decrease,pH value of 4U treatments was significantly increased and other treatments was reduced in comparison with the CK;NH3-H/TN of U and U + CP treatments were higher than that of other treatments;Lactic acid in CK was significantly lowered than that of other treatments except for 4U +0.4CP treatment;Acetic acid contents in the urea or U + CP treatments was significantly higher than that of the CK,and acetic acid contents in the CP treatment were significantly lower than that of the CK;Propanoic acid content in all treatments was significantly higher in comparison with the CK.These results suggested that adding 4％ urea + 0.2％ CP to yellow corn stalks could effectively improve corn stalks fermentation quality.关键词
