Variation in feed intake and egg shell strength during a 14-day period



Variation in feed intake and egg shell strength during a 14-day period



Poultry Science 59(7): 1617



The day-to-day patterns for feed intake and egg shell strength of 24 force moulted hens from each of 2 experimental strains were studied during 14 consecutive days. There were differences between strains for egg weight and shell strength. The results indicate that a number of eggs from a hen should be studied in order to get an accurate estimate of egg shell strength, not only to reduce the standard error of the estimate but also to smooth out any systematic daily variation.
