The use of antibiotics as a growth promoter in poultry feed has been restricted in many countries across the world. Therefore, there is a need in finding possible alternatives for growth improvement and disease prevention in the poultry industry. Probiotics are considered as one of the alternative feed additives to antibiotics. Probiotics can be defined as microbial feed supplements which beneficially affect the host by improving its gut microflora. Probiotics enhance the growth and production of poultry birds, protect the host against pathogens, enhance the immune system and improve bone strength.
Changes in growth performance frequently affect several meat quality traits. Many recent investigations show that using probiotics as dietary supplements exhibit potential as a natural way to improve poultry meat quality.
