Turkey hens were exposed to lighting regimens of 14 hours per day (C) or 5 intermittent 1 hour light periods spaced equally during 14 hours per day (I). Egg production at 84, 120 and 180 days of lay, average clutch length and number of clutches were not affected by lighting treatment. In large weight hens, rate of lay was less in regimen I, but not in medium weight hens. Hens in regimen I laid about one more floor egg per hen than those in regimen C, and were more difficult to nest train. Number of broody periods, total days broody, average broody period length and effective days of egg production were not affected by lighting regimen in either medium or heavy weight hens. Fertility, hatchability and number of poults per hen were also not affected. Feed per egg was not significantly different, but was in favor of regimen I. Estimated savings in production costs in favor of regimen I were equal to two fertile eggs. Data are also reported for the above traits concerning regimen C with the presence of sexually mature males in cages within the pens, regimen I with a gradual change to regimen C starting at 56 days production, and regimen C with an increase in the light period of 15 minutes every two weeks. These three regimens were studied for only one year each. The results are thus preliminary in nature, but indicate responses to all the traits not greatly different from regimen C.
