Description
Muhammed Tilahun and colleagues feed black cumin seed meal to broiler chickens in a 2026 feeding trial. The meal is the pressed residue after oil extraction from Nigella sativa seeds. Feed eats most of poultry production cost, so cheap local by-products attract interest in Ethiopia. Diets included the meal at graded levels up to about four and a half percent. The team measured growth, feed conversion, deaths, gut bacteria, and profit.
Growth held steady at every inclusion level tested. Feed conversion improved at the highest level, and deaths fell significantly in meal-fed groups. Gut samples showed fewer Escherichia coli and coliform bacteria, with more Lactobacillus present. The meal groups also returned higher net income and better returns. The authors present the by-product as a practical partial substitute in broiler feed. It tackles cost pressure and gut health at once.
