Ask for help: broiler feed stool

Broiler 20 th or so, serious over-feed, chicken farm has been more than a month. I would like to ask what may cause it and how to solve it. Urgent-what reason I don't know, it can be solved with a little bit of speed and fat! 10 ppm-- metronidazole drinking water, four andrographis paniculata mixture Just three days-try adding a little acidifier to improve digestibility and kill intestinal bacteria. -- it's not easy to solve, if you solve it, send a post to tell you-- I think first find out what caused it, and then take corresponding measures, can you post the recipe? -- intestinal dysfunction caused by massive abuse of antibiotics before 20 days of age. Antibiotics not only treat diarrhea, but also kill a large number of intestinal beneficial bacteria-- now many dealers for profit Technicians use medicine desperately in order to get a commission. Broilers in many areas use medicine every day from the age of 1 day to the end of the column. As soon as the medicine is stopped, the material changes, serious diarrhea, and complains that the effect of the medicine is not good. In fact, few front-line technicians know the real pharmacological knowledge at all. Undergraduates who have systematically studied theory seldom become technicians.-- to give you a good suggestion, it can reduce the intestinal disease of broilers in the future. Broilers can use prophylactic for 3 days after making vaccine, and choose broad-spectrum drugs that do little harm to kidney. Don't misuse kidney medicine. Broiler breeding focuses on management.-- Don't you see that many feed mills recruit technicians with a college diploma? But I am not saying here that junior college students are not good, their practical operation skills are still good, mainly theoretical and systematic knowledge, and the comprehensiveness of considering problems is poor. Many of the causes of overfeeding are caused by disease. What is the color of feces? what is the mortality rate? Do you have a picture? -- I think we should first find out what caused it, and then take corresponding measures to achieve a definite target.
