Fertility and hatchability of eggs produced by New Hampshire breeders during their first 365 days of production



Fertility and hatchability of eggs produced by New Hampshire breeders during their first 365 days of production



Poultry Sci 37(1): 27-29



Test hatches were made of eggs produced by 12 flocks of New Hampshire breeders hatched each month of the year. Percentage of fertile eggs varied more during the 1st 50 days of production than in any subsequent 50 day period. The fertility of eggs and hatch of total eggs remained uniform during the first 250 days of production after which time significant decreases occurred. The percentage hatch of fertile eggs declined approximately 5 percentage points during the 251-365 day period, and was significantly lower than the percentage hatch during the 151-250 day period.
