Abstract
FORCED molting has been studied for many years as a possible method of rejuvenating hens to increase egg production and egg quality. Although recommended by a few poultrymen, Rice (1905) was skeptical that the practice would be profitable.More recent results have been variable and the advantages and disadvantages have been summarized by Cox (1964) and Bell (1965). In addition, force molting has been reported to improve poor fertility in turkeys (Moyer et al., 1966) and to increase the DDT depletion rate in hens (Wesley et al., 1966).The method most commonly used for inducing a molt has been some type of feed and/or water restriction such as that suggested by the Poultry Council of the State College of Washington (1947). Noles (1966) reported that feed and water restriction is an effective method of force molting.Progesterone has been shown to be effective in causing a cessation of lay accompanied .
