In broiler chicken production, the health of the small intestine is crucial for optimal growth. Pathogenic microbes in the small intestine can infect the digestive tract, causing inflammation and nutrient absorption issues, leading to suboptimal growth.
In recent decades, antibiotic growth promoters (AGP) have been used by farmers to enhance broiler chicken growth performance, administered through feed or drinking water. However, in 2018, the Indonesian government officially banned the use of AGP as additives in livestock due to concerns about AGP residues in chicken meat, which could increase bacterial resistance and cause allergic reactions in humans.
