Transplantion of predominant Lactobacilli from native hens to commercial hens could indirectly regulate their ISC activity by improving intestinal microbiota.

ABSTRACT: In poultry, HyLine (HL) Hens are known for their excellent laying performance. However, ZhenNing (ZN) Hens, a native chicken breed in China, are known for their unique flavour. The intestinal mucosa, which is the main organ for nutrient absorption, could affect livestock product quality. In ZN Hens' intestinal mucosa, we found more villus wrinkles, larger villus circumference and higher amino acid transporters mRNA abundance compared with HL Hens. Among three laying periods of ZN Hens, in the intestinal lumen, Lactobacillus salivarius (L. sa.), Lactobacillus agilis (L. ag.) and Lactobacillus aviarius were the predominant species in the laying peak period. Furthermore, multiple-antibiotics feeding in ZN Hens and predominant Lactobacillus feeding in HL Hens suggested that these Lactobacilli
