Effect of fecal microbiota transplantation on early intestinal immune function and histomorphology of immune organs in chicks.

Unlabelled: The intestinal microbiota drives the maturation of the immune system, which is essential for maintaining lifetime homeostasis. Whether fecal microbiota transplantation can promote the development of the immune system in chicks? On days 1, 3, and 5, the post-hatch Hy-line Brown chicks were treated with fecal suspension from breeding hens. Intestinal length, blood biochemical indicators, the morphology of immune organs, and intestinal immunity-related indicators were focused on days 7 and 14.

Donor selection for fecal bacterial transplantation and its combined effects with inulin on early growth and ileal development in chicks.

Aims: To select the best donor and investigate its combined effects with inulin on growth performance, and ileal health of chicks.

Methods And Results: The chicks (Hy-line Brown) were treated with fecal microbiota suspension from different breeder hens to select the best donor. Treatment with fecal microbiota transplantation (FMT) alone or in combination with inulin resulted in improvement in gut microbiome in chicks.

Maternal effects drive intestinal development beginning in the embryonic period on the basis of maternal immune and microbial transfer in chickens.

Background: Nutrition drives immunity and health in animals, and maternal immunity benefits offspring. In our previous study, a nutritional intervention strategy was found to promote the immunity of hens, which subsequently improved immunity and growth in offspring chicks. Maternal effects clearly exist, but how are mothers' immune advantages transferred to their offspring, and how do they benefit them?

Results: Here, we traced the beneficial effects back to the process of egg formation in the reproductive system, and we focused on the embryonic intestinal transcriptome and development, as well as on maternal microbial transfer in offspring.
