Effect of Brevibacillus laterosporus Probiotic on Hematology, Internal Organs, Meat Peroxidation and Ileal Microflora in Japanese Quails Fed Aflatoxin B۱

In order to investigate the Aflatoxin B۱ (AFB۱) removal ability of Brevibacillus laterosporus (Bl), ۱۲۵ male Japanese quails aged ۲۱-day-old were divided into ۵ experimental groups with ۵ replicates of ۵ birds each. The experimental groups were control (basal diet), Bl (basal diet+۱۰۸ cfu Bl mL-۱), AFB۱ (basal diet+۲.۵ mg AFB۱ kg-۱), AFB۱+Bl (basal diet+۲.۵ mg AFB۱ kg-۱ and ۱۰۸ cfu Bl mL-۱), and AFB۱+Improved Milbond-TX® (basal diet+۲.۵ mg AFB۱ and ۲.۵ g Improved Milbond-TX® kg-۱). The AFB۱ decreased hematocrit (P= ۰.۰۰۳), red blood cells (P< ۰.۰۰۱), and white blood cells (P= ۰.۰۱۲) compared to the control while Bl probiotic improved those parameters. The highest relative liver and heart weight and lowest foam production and relative weight of bursa of Fabricius were observed in AFB۱ group (P< ۰.۰۵). However, the relative weight of bursa of Fabricius and cloacal gland of birds fed Bl were similar to those in the control group. The low oxidation stability of meat samples resulting from the use of AFB۱ improved due to use of Bl probiotic (P< ۰.۰۰۱). The ileal population of Escherichia coli increased in AFB۱ group while the lactic acid bacteria decreased. This condition was reversed due to administration of Bl probiotic (P< ۰.۰۰۱). This study clearly showed that indigenous Bl probiotic could be effectively used to lessen the negative effects of AFB۱ on meat quality and microbial ecosystem of growing quail chicks.
