Antibiotics have been added to animal feed since the 1950s. They have helped to quickly increase the muscle mass and size of livestock, and thus produce more meat. In addition, using them was supposed to prevent diseases.
The use of antibiotics in the meat industry carries with it several negative impacts on human, animal, and ecosystem health, such as:
• Increase in antibiotic-resistant bacteria that can infect humans and animals,
• Change in the composition of the intestinal microbiota of farm animals,
• More frequent inflammation,
• Reducing the usefulness of antibiotics.
The makeshift use of antibiotics is slowly being abandoned for healthy livestock.
A pure feed with only probiotic admixture, devoid of agents that stimulate rapid muscle mass gain, gives much better results in maintaining the overall health of poultry farming and other animal species.
The positive effects of Bacillus subtilis are based on
• Reduction of colonization of Salmonella typhimurium bacteria,
• Reduction of gut pathogens,
• Optimizing Gut Function,
• Better absorption of nutrients,
• Increasing the number and length of intestinal microvilli.
