Abstract

Low hatchability of eggs in some breeds of turkeys has long been a serious problem among turkey raisers over the entire United States. The average hatchability is approximately 65 per cent in all breeds; however, in the broad-breasted bronze variety the hatchability is only 47 per cent (1). In the Intermountain areas those hatches are appreciably lower (2). The broad-breasted bronze turkey is one of the larger breeds and is one of the best-selling varieties. Due to the initial high cost of turkey eggs (35 to 48 cents each) and the high mortality during incubation, considerable sums of money have been lost each year by the turkey industry. It has been estimated that over $200,000 a year is lost in Utah at the present time because of low hatchability of eggs.
