Use of a microbial endocrinology designed dopamine-producing probiotic to control gut neurochemical levels associated with the development of gut inflammation

mycolabadmin

Researchers developed a special probiotic bacteria (Enterococcus faecium) that produces dopamine, a mood-boosting chemical, to reduce inflammation in chickens’ digestive systems. When combined with L-dopa (a dopamine precursor found in Mucuna beans), this probiotic successfully lowered levels of norepinephrine, a stress chemical that promotes gut inflammation. This approach could help poultry farmers improve chicken health and growth without using antibiotics, which are no longer permitted in feed.

In vitro compatibility screening of Bacillus pumilus and Bacillus altitudinis strains with selected candidate prebiotics for in ovo application of synergistic synbiotics

mycolabadmin

Researchers tested different beneficial bacteria (Bacillus strains) and food additives (prebiotics) to create improved formulations for chicken embryos. They found that certain plant-based additives, especially protein hydrolysate, worked particularly well with specific bacterial strains. When they tested the best combination in developing chicken eggs, it was completely safe and didn’t affect hatching rates, suggesting this approach could be used to give chicks a healthier start in life.

A Review on Aspergillosis in Turkey: As a Main Fungal Disease in Poultry

mycolabadmin

Aspergillosis is a serious fungal disease affecting turkeys, especially young birds, caused by breathing in fungal spores from moldy hay, compost or poorly ventilated housing. The disease causes respiratory problems, can spread to other organs, and can kill 30-50% of affected flocks. Prevention through good ventilation, clean housing and dry feed is more effective than treatment since few antifungal drugs are approved for food animals. Understanding how environmental conditions promote this disease is key to protecting turkey populations.

Modulating effects of Phellinus linteus polysaccharides on antioxidant capacity, immune function, intestinal function and microbiota in lipopolysaccharide-challenged broilers

mycolabadmin

Researchers studied how a medicinal mushroom extract called Phellinus linteus polysaccharides could help broiler chickens recover from immune stress caused by bacterial toxins. The supplement improved the chickens’ growth, reduced harmful inflammatory responses, and promoted beneficial gut bacteria while reducing harmful ones. The treatment strengthened the intestinal barrier and restored the chickens’ natural antioxidant defenses. This suggests the mushroom supplement could be a natural alternative to antibiotics for improving poultry health on farms.
