Cross-breeding programs select for smaller-sized birds with efficient digestive systems, enabling them to effectively digest and utilize fibrous diets, including agricultural by-products, thereby lowering feed costs.
How do cross-breeding programs aim to reduce the size of egg-laying birds while enhancing their ability to utilize cheaper, fibrous diets?
