A recent visit to the Jilin market found that some laying hens did not express well in laying eggs, mainly in the early stage of the newly-started production of chickens, the egg production rate reached80%（140-150Days) Slow egg growth (180Day egg production rate is only up88%-89%), partial peak(30-35Weeks of age)The egg production rate has also dropped88%-89%Even lower (80%）。
On-site observation: chicken crowns are whitish, thinner and have inverted crowns. When feeding, chickens do not have a strong desire to eat, and there are more particles left at the bottom of the trough. Tapeworms, red stool and overfeeding can be seen in feces. The color of eggs is light, the quality of eggshells is deviated, and there are relatively more damaged eggs. Chickens are thin (180Balance average weight3.4Jin)
On-site autopsy findings: white pseudomembranes and ulcers were found in the oral cavity, white colonies were found in the crop mucosa, glandular gastric papilla swelling, ulcers and bleeding, duodenal mucosa swelling and thickening, mucosa in the middle part of the small intestine shedding, intestinal wall thin and brittle, intestinal overfeeding, and undigested feed particles in the intestinal cavity.
Disease analysis: enter7Since January, the area has been rainy and rainy, with high air humidity and high temperature, causing corn to absorb moisture and mildew on the surface. However, farmers have insufficient understanding of mold and mycotoxins, which makes the mold and mycotoxins in the diet seriously exceed the standard. After a period of accumulation, it will show clinical symptoms after reaching a certain amount.
Treatment direction:
1.deworming Exemption from parasitoid predation of chicken body nutrition
2.Control of mold and mycotoxin content in diets Starting from the source, reduce mold and mycotoxin damage to chickens.
3.Administration of drugs for the treatment of mold and glandular gastritis symptomatic treatment, in order to enhance the chicken feeding desire, rapid recovery of physical fitness.
4.Adding vitamins to the dietA VitaminsACan quickly repair mucosal epithelial cells
5.The addition of glucose and Anchi Weisheng Kang in the diet can help chicken liver accelerate the degradation of mycotoxins and improve intestinal flora and reduce overfeeding.
