摘要
为研究添加剂对燕麦草青贮品质的影响,选用甲酸和山梨酸钾-苯甲酸钠处理青贮燕麦。结果表明,甲酸处理和山梨酸钾-苯甲酸钠处理显著提高了青贮燕麦的感官品质、化学品质和饲料营养品质。甲酸添加量为3 L/t原料草,22%苯甲酸钠和14%的山梨酸钾制成溶液2 L/t原料草可显著提高燕麦的青贮品质。
In order to study the effect of additives on the quality of oatgrass silage,formic acid and potassium sorbate-sodium benzoate were used to treat silage oats.The results showed that formic acid treatment and potassium sorbate-sodium benzoate treatment significantly improved the sensory quality,chemical quality and feed nutritional quality of silage oats.The addition of formic acid is 3 L/t raw grass,22%sodium benzoate and 14%potassium sorbate make a solution of 2 L/t raw grass can significantly improve the silage quality of oats.
