Research note: lack of effect of a live yeast culture on broiler breeder and progeny performance.
Broiler breeders were fed corn and soybean diets containing 0, .1, .3, or .5% of a live yeast culture from 21 through 64 wk of age. In addition to assessing various breeder reproductive variables, chicks from each treatment level were grown to 17 days of age at 30, 40, 50, and 60 wk of breeder age. With the exception of a significant decrease in fertility at the .3% level, there were no effects on broiler breeder or progeny performance.
