After a large number of statistical investigations, it was found that the reasons of laying hens spitting water were concentrated in these three kinds: candidiasis, mycotoxin poisoning and eating rancid feed. The following Lao Wang will give you an analysis of the prevention and treatment of laying hens spitting water in these three cases.
1, candidiasis (crop disease)
This is a fungal disease of chicken upper digestive tract caused by Candida albicans. The reason may be the growth of fungi in the waterline. Some chickens with poor constitution or lack of vitamin A are easily infected and spit water, which will make the trough wet. Other chickens can also be infected with candida when pecking at feed and drinking water. Finally, more and more chickens spit water.
Chickens with hydatid disease will have difficulty swallowing, their food intake will gradually decrease, and they will gradually lose weight. After dissection, it was found that the crop formed a white false film, the color of the crop became lighter, and inflammation appeared on the inner wall of the crop.
Prevention and treatment: clean the waterline regularly, put an end to the use of moldy feed, add antifungal drugs to the feed, conduct targeted treatment, and be sure to pay attention to reducing the use of antibiotics. During the use, 500g/ ton feed of Longchang bile acid can be used for ten days, which can discharge the produced toxins and repair the liver injury.
Step 2 eat rancid feed
Chickens eating spoiled feed will ferment abnormally in crops, producing acid and gas, which will cause crops to swell. When the chicken bows its head, it will shed sour and sticky liquid in its mouth.
Prevention and control: moisture-proof feed, reduce storage time, and implement the principle of "first come, first feed". Don't put the feed in the trough for too long, feed it less many times, and strive for free trough time every day. Reasonable use of equipment to prevent water from entering the tank. 0.3~0.5% baking soda is added to the feed for prevention and treatment, and 7 days is a course of treatment.
3, mycotoxin poisoning
The mycotoxin here is mainly emetic toxin When the feed contains mycotoxin, the toxin will accumulate in chickens during continuous feeding, which will eventually lead to poisoning. When vomiting toxin is poisoned, laying hens will spit water and diarrhea, and the color of spit water is generally light brown. There are dark brown contents in anatomical crops and glandular stomach, severe ulcer of musculo-gastric stratum corneum, swelling of glandular stomach and mucosal erosion. The liver is swollen and yellow in color.
Prevention and treatment: Do not use feed or feed raw materials with excessive mycotoxin, use mildew remover regularly or for a long time, and use Longchang bile acid and bile acid as excretory fluid regularly every month, which can discharge a small amount of mycotoxin eaten by chickens, protect the liver and gallbladder health of laying hens and prevent toxins from accumulating in laying hens.
Candidiasis, feed rancidity and mycotoxin are the three common reasons for laying hens to vomit milk. The spitting of laying hens is only a superficial phenomenon, and the spitting lasts for a long time, which will cause the weight loss of chickens and affect the production of laying hens. In the process of feeding, we must carefully manage and cultivate the feeding thinking that prevention is greater than cure to avoid these unnecessary losses.
