In order to investigate the effects of dietary probiotics supplementation on laying performance, egg quality, serum hormone levels, immunity, antioxidant, and gut microbiota layers at different stages, a total 168 Tianfu green shell hens (28-day-old) were randomly divided into 2 treatments: non-supplemented control diet (NC), supplemented with 10 g/kg probiotics, respectively. Each treatment had 6 replicates 14 per replicate. The feeding trial lasted for 54 weeks. results showed that significantly increased average weight, improved quality ( p < 0.05) ovarian development.

The Impact of Early-Life Cecal Microbiota Transplantation on Social Stress and Injurious Behaviors in Egg-Laying Chickens

Microorganisms, Journal Year: 2024, Volume and Issue: 12(3), P. 471 - 471

Published: Feb. 26, 2024

Injurious behaviors (i.e., aggressive pecking, feather and cannibalism) in laying hens are a critical issue facing the egg industry due to increased social stress related health welfare issues as well economic losses. In humans, stress-induced dysbiosis increases gut permeability, releasing various neuroactive factors, causing neuroinflammation neuropsychiatric disorders via microbiota-gut-brain axis, consequently increasing frequency intensity of aggression violent behaviors. Restoration imbalanced microbial composition has become novel treatment strategy for mental illnesses, such depression, anxiety, bipolar disorder, schizophrenia, impulsivity, compulsivity. A similar function modulating following challenge may be present egg-laying chickens. The avian cecum, multi-purpose organ, greatest bacterial biodiversity (bacterial diversity, richness, species composition) along gastrointestinal tract, with vitally important functions maintaining physiological behavioral homeostasis, especially during periods stress. To identify effects microbiome on injurious chickens, we have designed tested transferring cecal contents from two divergently selected inbred chicken lines stress-related recipient chicks commercial layer strain.

Intestinal bacteria, functionally as an endocrine organ second brain, release various immunomodulators bioactive compounds directly or indirectly regulating host’s physiological behavioral homeostasis. Under challenges, stress-induced dysbiosis increases gut permeability causes serial reactions: releasing neurotoxic compounds, leading neuroinflammation neuronal injury, eventually aggressive, violent, impulsive behavior in humans animals via complex bidirectional communication microbiota–gut–brain (MGB) axis.

Despite their growing popularity as alternatives to antibiotic growth promoters (AGPs), the individual effects of nucleotides and probiotics on poultry gut functionality remain poorly understood. In addition, inconsistent outcomes are quite common in studies where these two additives have been used separately modify function related parameters birds. These inconsistencies, which limited potential AGP replacements, stem from various factors need be addressed. Combining could potentially enhance effectiveness lead more consistent layer chickens. Since mechanisms action complement each other, some level synergy is expected when together. Both shown support health, boost immune function, improve performance chickens individually.
