Abstract: A magnesium-enriched vegetable feed composition for a layer which improves the eggshell quality and which prevents the occurrence of shell mottling. The feed consists essentially of a vegetable feed, the magnesium content in said vegetable feed being in the range of 0.21-0.28% by weight.

Abstract: A liquid feed containing 1.about.10% by weight of monosaccharide alone or in combination with 0.1.about.1.0% by weight of sodium bicarbonate is fed to broiler chicks, layers or breeders in the summer season, thereby preventing reduction of body weight increase rate in broiler chicks as well as reduction of egg production yield in layers or breeders, and further preventing the mortality of broiler chicks, layers or breeders caused by heatstroke. In addition a liquid feed containing 1.about.10% by weight of monosaccharide alone or in combination with 0.1.about.1.0% by weight of sodium bicarbonate is fed to layers in a later stage at an ordinary temperature or at lower temperature thereby preventing production of extra large eggs which does not meet standard requirements.
