Description

假蒟提取物在制备防治禽类曲霉菌病的添加剂中的应用
本申请要求于2021年03月30日提交中国专利局、申请号为202110341832.X、发明名称为“假蒟提取物在制备防治禽类曲霉菌病的添加剂中的应用”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本发明涉及禽类养殖技术领域，尤其涉及假蒟提取物在制备防治禽类曲霉菌病的添加剂中的应用。
背景技术
禽曲霉菌病是养鸭业中常见的一种真菌性疾病，尤其在幼鸭中发病较多，死亡率较高，可达50％。引起禽曲霉菌病的病原菌为曲霉菌，包括烟曲霉菌、黄曲霉菌、黑曲霉菌、土曲霉菌和青曲霉菌等。海南天气高温高湿，饲料、垫草易霉变，养殖环境中霉菌孢子较多，尤其在海南夏季该病为鸭养殖中的常见疾病。该病的临床症状为呼吸困难，张口喘气，呼吸次数增多，食欲不振，喜喝水，爱睡觉，拉淡绿色稀便，常呆立或卧在角落处，口腔和鼻腔常流出粘性分泌物。目前该病的治疗没有特效药，用1‰硫酸铜、1‰碘化钾、0.05％克霉唑、0.5万IU制霉菌素具有明显的疗效。
随着我国经济的发展，人民生活水平的日益提高，对肉制品的品质要求也不断提高。用中草药替代抗生素作为饲料添加剂是发展趋势之一，这对鸭养殖业绿色健康发展具有重要意义，并对为社会提供健康肉、蛋起到重要作用。但目前尚未见关于防治鸭曲霉菌病的中草药的报道。
发明内容
有鉴于此，本发明要解决的技术问题在于提供假蒟提取物在制备饲料添加剂中的应用。
本发明提供了假蒟提取物在制备防治禽类曲霉菌病的添加剂中的应用。
本发明中，所述禽类曲霉菌病由烟曲霉菌、黄曲霉菌、黑曲霉菌、土曲霉菌和青曲霉菌导致。
本发明中，所述禽类曲霉菌病为鸭曲霉菌病。
一些实施例中，所述鸭曲霉菌病为红毛鸭的曲霉菌病。
本发明中，所述假蒟提取物为假蒟的水提物或假蒟的醇提取物。
本发明实施例中，所述假蒟的水提取物的制备方法为，将假蒟以水回流提取三次，合并提取液经浓缩获得假蒟水提物；所述三次提取中，第一次提取3h，第二次提取2h，第三次提取1h。所述第一次提取中，假蒟与水的质量体积比为1kg∶0.5L；第二次提取中，假蒟与水的质量体积比为1kg∶0.4L；第三次提取中，假蒟与水的质量体积比为1kg∶0.3L。
本发明实施例中，所述假蒟的醇提取物的制备方法为，将假蒟以乙醇浸提三次，合并提取液经浓缩获得假蒟醇提物；所述三次提取中，第一次浸提7天，第二次浸提5天，第三次浸提3天。所述第一次提取中，假蒟与乙醇的质量体积比为1kg∶2L；第二次提取中，假蒟与乙醇的质量体积比为1kg∶1.5L；第三次提取中，假蒟与乙醇的质量体积比为1kg∶1.5L。所述乙醇为95％的乙醇。即乙醇-水以体积比95∶5混合的溶液。
本发明还提供了一种添加剂，其包含假蒟提取物。
本发明所述的添加剂可以添加在饲料中，也可以添加在饮用水中，本发明对此不做限定。其添加在饮用水中的添加量为1％。即添加至假蒟提取物在饮用水中的质量分数为1％。
本发明还提供了一种禽类的饲养方法，其为给予本发明所述的添加剂。
本发明实施例中，所述给予的时间为7日龄，连续给予一周。
本发明研究发现假蒟水提物和醇提物对烟曲霉、黄曲霉、黑曲霉、土曲霉等曲霉属真菌存在抑制作用，并验证假蒟提取物能够用于防治禽类由于曲霉感染引起的呼吸道、肠道疾病，有效率可达81％～84％。并且，假蒟的植物资源分布广泛、生物量大、价格低廉，尤其在海南林下、路边 随处可见，所述提取物制备工艺简单、成本低、得率高，易进行大规模生产。
具体实施方式
本发明提供了假蒟提取物在制备饲料添加剂中的应用，本领域技术人员可以借鉴本文内容，适当改进工艺参数实现。特别需要指出的是，所有类似的替换和改动对本领域技术人员来说是显而易见的，它们都被视为包括在本发明。本发明的方法及应用已经通过较佳实施例进行了描述，相关人员明显能在不脱离本发明内容、精神和范围内对本文的方法和应用进行改动或适当变更与组合，来实现和应用本发明技术。
本发明采用的试材皆为普通市售品，皆可于市场购得。所述的中草药假蒟别名蛤蒟、不拨子、假荖、蛤荖、假蒌、蛤蒌、木柄蒌、荜拨子、猪拨菜、钻骨风、臭蒌、山蒌、马蹄蒌为胡椒科(Piperaceae)胡椒属(Piper L.)假蒟(Piper sarmentosum Roxb.)具祛风散寒，行气止痛，活络，消肿的功效，用于风寒咳喘，风湿痹痛，脘腹胀满，泄泻痢疾，产后水肿，跌打损伤(《中华本草》)。所述假蒟提取物的制备可以采用假蒟全草，也可采用部分组织器官。在提取前，经过干燥、粉碎的步骤。本发明实施例中，采用假蒟全草制备假蒟提取物。
下面结合实施例，进一步阐述本发明：
实施例1
干燥的假蒟全草1kg，粉碎后放入5L三角瓶中，加入95％的乙醇2L，常温浸泡7天，回收提取液；加入1.5L 95％的乙醇继续浸泡5天，回收提取液；再次加入1.5L 95％的乙醇继续浸泡3天，回收提取液，合并3次浸提液，减压浓缩得假蒟乙醇提取物110g。

实施例3
实施例1和实施例2制得的假蒟提取物的抑菌实验
活化目标菌株，稀释到菌数1×10 6CFU/mL的菌液备用；制备好YPD无菌平板；取0.1mL制备好的菌液用无菌棉签均匀涂布于YPD平板上；分别将实施例1～2的假蒟提取物用甲醇溶解，配制成浓度为10mg/mL的溶液；将克霉唑用丙酮配制成浓度为10mg/mL的溶液，取药液10μL分别滴加到直径为6mm的无菌滤纸片上，至溶剂挥发完后将滤纸片置于涂布好目标菌液的平板上，每个平板放6张滤纸片，密封好平板倒置于28℃培养箱进行培养24小时，用游标卡尺测量抑菌斑直径(mm)。该抑菌实验所用目标菌为烟曲霉菌、黑曲霉菌、黄曲霉菌；每种菌抑制实验设置3个重复，每个重复包括10mg/mL假蒟提取物、10mg/mL克霉唑(阳性对照)、甲醇(空白对照)各2片滤纸片。测试效果见表1：
表1实施例1～2制得的假蒟提取物抑菌实验(单位mm)
  烟曲霉菌 黑曲霉菌 黄曲霉菌
实施例1提取物 21.41±1.71 27.35±1.62 18.14±1.22
实施例2提取物 22.15±1.31 26.72±1.47 20.36±1.43
克霉唑 24.36±1.17 28.43±1.75 21.78±1.64
甲醇 0±0 0±0 0±0
从表1数据体外抑菌实验可以看出，本发明所述的两种方法制备的假蒟提取物对曲霉菌属中的3个菌抑制效果都较好，这3种曲霉菌是导致鸭曲霉菌病最常见的病原菌。通过上述实验说明假蒟提取物可以用于防控鸭曲霉菌病。
实施例4
在实施例3的基础上对实施例1和实施例2制得的假蒟提取物的抑菌实验
把假蒟提取物用DMSO溶解到1mg/mL的初始浓度，以克霉唑为阳性对照用DMSO溶解到1mg/mL的初始浓度，DMSO为空白对照。在96孔板上用无菌培养基按照2倍法进行梯度稀释，稀释好后加入待测菌，培养12小时后观察。本实验设置3个重复。
表2实施例1～2制得的假蒟提取物MIC实验(单位μg/mL)
  烟曲霉菌 黑曲霉菌 黄曲霉菌
实施例1提取物 10～25 25～50 50～75
实施例2提取物 25～50 10～25 25～50
克霉唑 0.65 0.65 1.26
DMSO >100 >100 >100
从表2 MIC实验数据可以看出，本发明所述的假蒟提取物对曲霉菌属中的3个菌最小抑制浓度均小于100μg/mL，说明该提取物对上述3种曲霉菌有一定抑制效果，可以用于防控鸭曲霉菌病的饲料添加剂。
实施例5
实施例1和实施例2制得的假蒟提取物的鸭曲霉菌病防治试验
在儋州某稻田鸭养殖场进行该试验，试验时间为7月份，正是海南高温高湿，曲霉菌病高发季节，所试验鸭为红毛鸭7日龄幼苗。选择120只确证患曲霉菌病的7日龄鸭分4组进行试验，每组30只。以上试验对象分别以假蒟提取物1％的水溶液，克霉唑0.05％的水溶液，水(空白对照)，代替饮用水进行试验，连续饲养1周，评估防治效果，治疗效果判定标准为：
治愈：鸭食欲、活动精神恢复正常，粪便颜色正常，干稀适度。
死亡：防治期内鸭病情无明显改善而死亡。
有效：鸭食欲、活动精神有明显改善，下痢次数减少，有效数包括治愈数。
无效：在防治期间鸭病情无明显好转，甚至加重，但不包括死亡数。评价结果如表3。
表3实施例1～2制得的假蒟提取物的鸭曲霉菌病防治试验
  死亡率％ 治愈率％ 有效率％ 无效率％
实施例1提取物 6.67 73.33 83.33 10.00
实施例2提取物 6.67 70.00 80.00 13.33
克霉唑 3.33 83.33 90.00 6.67
饮用水 53.33 6.67 13.33 33.33
由表3数据可以看出，本发明所述的假蒟提取物对曲霉菌导致的鸭霉菌病具有很好的防治作用，与对照组的克霉唑效果相比较，效果稍差，但足可以作为饲料添加剂对鸭曲霉菌病进行防控。
以上仅是本发明的优选实施方式，应当指出，对于本技术领域的普通技术人员来说，在不脱离本发明原理的前提下，还可以做出若干改进和润饰，这些改进和润饰也应视为本发明的保护范围。
