A very comprehensive detailed subject.
Thank you very much, sir, on the update.

What is the problem of finding E.coli and Clostridium perfringens in the feed after pelleting? Is it the simple presence or concentration of these bacterias? The reason for my question is that, in the gut of healthy birds we found concentrations of up to 10E4 or even higher of E. coli and C. perfringens without causing any problems. According to Disease of Poultry 14th Ed. 2020, the presence of E. coli in the lower intestine tract is benefical, aiding in growth, development and inhibiting other bacteria like Salmonella.
Don't you think that sometimes the problem is not the microbiology of food, but the disruption of the animals' microbiota?
