TAILIEUCHUNG - The Role of Probiotics in the Poultry Industry

Pesticide exposure to residues on surfaces, eggs and birds are minimal, representing little risk to workers. Once treated, birds are seldom handled by workers until removed from the houses at the end of a production cycle. Frequency of application also plays a role in reducing secondary exposure following premise treatments. Poultry houses are often treated just prior to the introduction of a new flock. In the case of broilers and young turkeys, premise treatments will occur at a minimum of every 7 to 8 weeks. Treatment intervals in turkey grow-out houses are approximately twice that. | Int. J. Mol.

These impacts are in part due to the indiscriminate use of chemotherapeutic agents as a result of management practices in rearing cycles. This review provides a summary of the use of probiotics for prevention of bacterial diseases in poultry as well as demonstrating the potential role of probiotics in the growth performance and immune response of poultry safety and wholesomeness of dressed poultry meat evidencing consumer s protection with a critical evaluation of results obtained to date. Keywords probiotics bacteria disease control meat quality poultry 1. Introduction The poultry industry has become an important economic activity in many countries. In large-scale rearing facilities where poultry are exposed to stressful conditions problems related to diseases and deterioration of environmental conditions often occur and result in serious economic losses. Prevention and control of diseases have led during recent decades to a substantial increase in the use of veterinary medicines. However the utility of antimicrobial agents as a preventive measure has been questioned given extensive documentation of the evolution of antimicrobial resistance among pathogenic bacteria. So the possibility of antibiotics ceasing to
