Do You Know Why Laying Hens Diarrhea？
蛋鸡拉稀的原因究竟有哪些
Laying hens diarrhea has gradually become a very troublesome problem for the feeders. Diarrhea can emit harmful substances within the digestive tract in some cases, that has a defensive role. But prolonged diarrhea will result large loss of water and electrolytes which cause dehydration and acidosis.
蛋鸡拉稀逐渐成为一个令蛋鸡饲养者非常头疼的问题。拉稀在某些情况下能排出消化道内的有害物质，有一定的防御作用，但长时间腹泻，造成水及电解质大量丧失，可引起机体脱水和酸中毒。
The diarrhea causes and mechanism are complex and multifaceted. The symptoms, pathology change and treatment measures are different mechanism with the disease mechanism, duration time. Only correct diagnosis, scientific and rational treatment, that can obtain satisfactory results.
拉稀的原因和机理是复杂的，多方面的，随原因机理、病程长短不同，其症状、病变及诊治措施也不一样。只有正确诊断，科学合理治疗，才能取得满意的效果。
What are the factors of diarrhea in laying hens?
蛋鸡拉稀究竟有哪些因素呢？
Physiological diarrhea:
From late breeding period to early stage of production, laying hens requires large amount of nutrients absorption because estrogen large secretion, ovarian and tubal development rapidly.
In addition to the dietary protein content and crude fiber content is too high, too much protein and crude fiber is difficult to digest and absorb, so as to stimulate the intestinal accelerate metabolism, which accelerate intestinal peristalsis, thus leading to the diarrhea occurrence in laying hens.
生理性的拉稀：
蛋鸡从育成后期到开产初期，由于雌激素大量分泌，卵巢和输卵管迅速发育，这期间需要大量营养物质的吸收。
加之饲料中蛋白质含量及粗纤维含量过高，过多的蛋白质及粗纤维难以消化吸收，从而刺激肠道加快代谢，使得肠道蠕动加快，从而导致蛋鸡腹泻病的发生。
During the laying period, the protein level is too high, resulting body incomplete absorption, which stimulating the intestinal tract, resulting in yellow stool thinning, feed conversion rate decreased. Another case is feed mildew also cause diarrhea.
饲料因素引起的拉稀：
产蛋期蛋白质的水平过高，导致机体吸收不完全，从而刺激肠道，导致粪便发黄发稀，饲料转化率降低。还有一种情况就是饲料发生霉变也会引起拉稀.
In order to enhance appetite, prevent feather pecking and anal pecking picking anus，some feeders add too
much salt in feeding, leading to severe diarrhea in laying hens.
Another reason is fish meal dosage is large or the fish meal contains much salt, which can also induce the disease.
Too much or too fast addition of stone powder in laying period.
饲料中食盐含量过大：
为增强食欲，防止啄羽、啄肛等现象发生，部分养鸡户在饲料中添加过多的食盐，导致鸡群出现剧烈腹泻。
另一原因是鱼粉添加量大或鱼粉本身含盐多，也会诱发本病。
产蛋期石粉的添加量过多或过快。
Bacterial disease, virus disease, bacterial infection disease and virus disease mixture will cause diarrhea disease in different degree. Such as: Escherichia coli, Salmonella pullorum, bursa and kidney etc..
疾病因素引起的拉稀：
细菌病、病毒病及细菌病与病毒病混合感染都会引起不同程度的腹泻病。如：大肠杆菌、白痢、法氏囊炎、肾传等。
The antibiotics abuse leads to intestinal flora imbalance, digestive disorders, that causing diarrhea.
滥用饲料引起的拉稀：
滥用抗生素导致的肠道菌群平衡失调，消化功能紊乱，从而引起拉稀。
SUMMARYIn summary, many factors that cause diarrhea, we must be combined with the actual situation, concrete analysis problems, can not use enteritis medicine once find diarrhea, thus have no good effect, also will cause body damage to the body and increase breeding cost.
The results showed that adding proper amount of bile acid in diet could improve the diarrhea of laying hens. Bile acids are not only digestive juices, but also excretory fluids. Bile acids participate in fat digestion and absorption as digestive juice. At the same time to improve the dietary fat absorption, bile acids can prevent nutritional diarrhea through the enterohepatic circulation to promote intestinal absorption of vitamin and trace elements.
As excretory fluids, bile acid can promotes liver bile secretion, dredge the biliary tract, the toxin accumulation in the liver and drug residue excreted, repair the liver and intestinal damage, maintain intestinal mucosal health, prevention of laying hens in autumn diarrhea, improve the laying rate。
综上所述引起拉稀的因素很多，我们一定要结合实际情况，具体问题具体分析，不能发现有拉稀的就盲目的投治疗肠炎的药，那样不仅效果不好，还会对机体造成损害，同时也增加养殖成本。
实验表明，饲料中添加适量胆汁酸可改善蛋鸡的腹泻现象。胆汁酸不仅是消化液，也是排泄液。作为消化液胆汁酸参与脂肪消化吸收的过程。提高饲料脂肪吸收的同时，通过肝肠循环促进肠道对维生素以及微量元素的吸收，预防营养性腹泻.
作为排泄液胆汁酸促进肝脏分泌胆汁，疏通胆道，将肝脏内蓄积的毒素和残留药物排出体外，修复肝脏和肠道损伤，维护肠道粘膜健康，预防蛋鸡秋季腹泻，提高产蛋率。
