What organic acids can be added to layer feed to improve brown eggshell pigmentation?

Incorporating organic acidifiers into brown layer feed formulations is a scientifically proven strategy to enhance shell pigmentation and overall flock health. By lowering the pH of the gastrointestinal tract, particularly in the duodenum and jejunum, organic acids increase the solubility of calcium carbonate and other essential trace minerals, making them highly bioavailable to the hen. This improved mineral absorption directly translates to a more robust deposition of protoporphyrin IX during the final stage of egg formation, leading to a richer, darker, and more uniform brown shell color. Additionally, organic acids act as strong antimicrobial agents, reducing the gut load of pathogenic E. coli and Salmonella. Farmers can analyze the cost-benefit of feed acidifiers by checking daily corn and soybean rates on Poultry Rates, purchasing certified feed additives through Poultry Plaza, and listing their premium dark-brown eggs on Murghi Mandi.
