The mortality rate is extremely low in the early stage, but secondary infection in the later stage results in extremely high mortality rate and severe growth and development impairment.
Necropsy symptoms: pericardial effusion, severe myocardial hemorrhage, glandular stomach swelling, bleeding or erosion, pus discharge, gizzard cuticle erosion, cracking or easy peeling, gizzard wall bleeding, ulcers, intestinal lymphatic filtration The vesicles are swollen, the intestinal wall is diffusely bleeding, the contents are sour and smelly or red or yellow viscous, the pancreas is red, the bursa of Fabricius is flushed, there are secretions inside, and some chicken kidneys are swollen.
2. Causes of chicken feed intake and treatment plans
Mycotoxins
Due to heavy rainfall in spring and summer, humid air and high temperatures, feed is prone to moisture and mold during storage and cannot be stored for a long time. Feed, mold poisoning generally shows gray mold nodules in the lungs, esophageal walls, and crops.
Treatment plan: Keep the chicken house dry during the rainy season, keep the feed free of mold, strengthen the ventilation inside the house, arrange the density reasonably, add mildew-proofing agent to the feed, add tons of feed per kilogram, and add stomachic loose meat to the mix. Livestock and poultry vitality, increase chickens' food intake.
, feed quality
Due to the increase in raw material prices and the decline in feed profit margins, many feed manufacturers add large amounts of cotton meal, soybean meal, and corn substitutes (such as soy protein, glycoprotein) to feed, resulting in poor feed quality. Excessive levels of toxic substances can stimulate the gastrointestinal tract of chickens and cause disease. Countermeasures: Replace with high-quality full-price feed.
, Prevention and control plan:
Use additives flexibly. In daily breeding, on the one hand, good feeding and management must be done, and on the other hand, some fermented traditional Chinese medicine for meat and poultry vitality r, which regulates the gastrointestinal tract and increases appetite, can be used to effectively increase the feed intake of pigs and protect their healthy growth to a large extent. It can prevent pigs from not eating and allow piglets to gain weight quickly.
