Let's Squawk About It

Why are egg prices on the rise?

Consumers entered 2023 with a bit of a price shock regarding eggs. However, is this price increase really that uncommon? Join us as we discuss increased egg prices with Darrin Karcher (Purdue University) along with some of the contributing factors. Egg prices fluctuate, but is it because of the supply chain, pushes towards new restrictions, or a combination of things?

Interpretive Summary

Investigating microbial presence in free range layers

A recent study published in The Journal of Applied Poultry Research sought to determine the best stocking density for free range layer flocks. Although there is no standard stocking density for free range layers, the researchers set out to identify if the common 1-1.5 square foot space per bird affected the spread of microbes to hens and their eggs.

Probiotics for Heat Stress

This short communication from Poultry Science® examines the effects of a probiotic, Bacillus subtilis, on neuroinflammation in heat-stressed broilers. The study did find that the probiotic improved brain immunity of heat-stressed broilers by reducing proinflammatory cytokines. The results also supported other findings that Bacillus subtilis supplementation reduces heat-related behaviors including panting and wing spreading.
