Rapid intestinal transit in broilers: This syndrome is common in poultry farming, caused by several triggers, such as the use of low-quality raw materials, microbial imbalances at the digestive level, mycotoxins, among many others. However, birds have rapid transit as a consequence of their accelerated metabolism, regardless of these factors, which aggravate it. Liquid faeces are observed, with undigested content, and productive parameters below standards.
