abstract
The modern system of swine production exposes the pigs to nutritional, management and climatic stress which causes physiological and psychological problems in swine. To overcome the stressor farmers use antibiotic which causes drug resistance and residual problem in pork. But the recent restriction on the use of antibiotics is due to the risk of drug residual effect in pork. It not only poses the risk of drug residue but also causes the emergence of antibiotic resistance in the microbe. To overcome this problem, the latest research reports suggest that Probiotic can be used in a judicial way which can help in the improvement of gut microbial population which indirectly causes improvement of health, immune system, enhancement in nutrient utilization, causes overall beneficial effect in swine production. The commonly used bacterial strains are Bacillus, lactic acid bacteria, Enterococcus and Saccharomyces cerevisiae. In this review, we will give you the overall status of the use of probiotics in swine nutrition.
