A comparison study of probiotic, postbiotic and prebiotic on performance and meat quality of broilers

Abstract

Using of antibiotics it has started nearly eighty years ago since 1940 the purpose of using for increasing the immunity against microbes, diseases and to enhance growth in poultry production. The development in bacteria to become resistant against drugs results from using antibiotics for long period it may transformed to humans as well. "Biotic" feed additives, such as probiotics, prebiotics, and postbiotics, are one potential option for increasing poultry development and health. More attention has recently been paid to modern dietary solutions, especially probiotics, postbiotics and prebiotics. A300 one day old Ross 300 chicks distributed randomly into five treatment three replicates twenty birds in each one. The treatment groups include: negative control (a basic diet), positive control (a basic diet) + oxytetracycline 0.05%, T1= a basic diet + 0.3% lactobacillus plantarum (postbiotic), T2= a basic diet + 0.3% Bacillus licheniformis (probiotic), T3= a basic diet + 0.3% Fructo-oligosaccharides (prebiotic). As a result of adding the natural additives to the feed, Birds fed T3 gained more live body weight and had significantly higher (p<0.05) than negative and positive control groups at the same time had lower (p<0.05) FCR. Moreover, carcass weight and bursa of fabricius were higher (p<0.05) in birds that were fed with T1 when compared with negative control. The group of birds that fed with T1, T2 and T3 decreased (p<0.05) drip loss and coocking loss. These natural supplements can be added to enhance growth performance and meat quality in chicken production.
