A study was undertaken to determine the influence of nutrient restriction between 6 weeks and 20 weeks of age on the reproductive performance of commercial turkey breeders. Females were restricted in feed intake to 70% or 60% of full-fed control hens. Males were restricted to approximately 50% of normal feed intake for the same period. The body weight of restricted fed females was significantly less than that of control hens at 20, 32, and 52 weeks of age. The restricted hens consumed approximately 10% less feed during the 6- to 52-week period than the control hens. There were no carry-over effects of feed restriction on rate of egg production, feed per egg, hatchability, fertility or egg weight. Also, restriction of feed for males had no subsequent effects on fertility of eggs.
