Key Points for Preventing and Treating Chicken Intestinal Toxemia Syndrome in Late Autumn

In late autumn, the climate changes abnormally, with large temperature differences between day and night. Broiler chickens and laying hens often develop intestinal toxemia syndrome, characterized by diarrhea, undigested feed in the droppings, a marked drop in feed intake, slow growth, weight loss, and dehydration. Necropsy of dead chickens reveals brain fluid in the head, reddened thymus in some birds, swelling of the duodenum, and thickening of the intestinal wall, which feels very hard to the touch. There is no feed in the intestinal tract, the intestinal mucosa has sloughed off in large amounts, and some intestinal segments contain frothy material and tomato-like droppings. The gallbladder becomes smaller and pale yellow, appearing as if there were no gallbladder at all.

The main measures to prevent the spread of this disease are isolating sick chickens, culling runts, removing litter, and carrying out thorough disinfection. For affected flocks, Qiu Jing (ball net) can be mixed with ribavirin in drinking water, given twice daily in the morning and evening, with electrolytes in the drinking water at noon, for 3 to 5 consecutive days. After the condition improves, use Su Bu 14 in drinking water for two consecutive days to restore the flock to good spirits. To prevent this disease, in addition to keeping the chicken house dry and hygienic and regularly using disinfectants for disinfection with chickens present or regularly mixing disinfectants into the supplementary grit, regular deworming is also needed to prevent the occurrence of colibacillosis and coccidiosis. In addition, when chickens are found to have loose droppings, do not easily diagnose it as enteritis and simply use enteritis medication, which can lead to intestinal flora imbalance and damage the intestinal mucosa.
