About the book
The use of antibiotics in food animals is largely in practice for decades. Poultry, as well as animal producers, use sub-therapeutic levels of antimicrobials in feed to get maximum production. Furthermore, in serval countries, non-judicial use of antimicrobials while using for therapeutic purposes is also been observed. However, research has evidence that the use of antibiotics in food animals has many deleterious effects on the animals, the environment, and human beings. One of the prime examples of antimicrobials' side-effects is the development of antimicrobial resistance that results in a reduction of treatment options in human and animal medicine. Nowadays, scientists are looking for viable alternatives to antibiotics including prebiotics, probiotics, and synbiotics. Probiotics are live microorganisms that are helpful for digestion and health. They are also capable to reduce harmful bacteria in the gut when supplemented in the diet. Many available studies show that probiotic supplementation in poultry, fish, livestock, and pet animals led to improved production, health, immunity, and meat quality.
