Development of a Fermentation Medium for Production of Probiotics and their Use in Feed for Laying Hens

In the current study, we performed in vivo investigation of probiotic intake influence on nuclear and mitochondrial DNA damage of hens, using quantitative PCR techniques. The probiotic supplementation to the diet of Hisex Brown hens had no significant effect on the rate of telomere shortening. After prolonged probiotic intake (225 and 445 days), the 18-21% decrease in the mtDNA lesions was detected. Since avian mitochondrial DNA damage investigations are rare, the current study of the probiotic-enriched diet's impact on the damage of the hen mitochondrial DNA is novel and highly important. The decrease of mtDNA damage is a beneficial property, which could positively affect the reproductive aging of hens. The positive impact of probiotic supplementation on hens' performance traits such as hen-day egg production, egg weight and mass, and feed conversion ratio was observed.
