Method of enhancing growth and weight gain in swine and block for use therein

摘要

A method for reducing stress in animals, such as pigs in an overcrowded breeder, by exposing a block to be licked by the animals. The block contains at least 50% by weight and preferably at least 70% by weight glucose, has a compressive strength over 5 kg/cm.sup.2 preferably 50-150 kg/ cm.sup.2, and a water content of 0.1-20% by weight. The block is too large to be swallowed by the animals and its compressive strength prevents crumbling. It is at least 50 g in weight, e.g. 500 g, and each dimension is more than 2 cm. The block is preferably secured above ground level and is slowly consumed by the animals by licking or pecking.
