摘要

For egg shell fortification, oyster shell is added to the layer diet. To elucidate the effects of oyster shell supplement in commercial diets on feed intake, laying performance, cracked egg frequency and profit, oyster shell was added throughout andduring peak and late periods of egg production by Single Comb White Leghorn hens from 20 to 88 weeks of age. Feed intake and egg mass were not influenced, but the incidence of cracked and shell-less eggs during peek production was slightly reduced by oyster shell supplementation. After 61 weeks of age, the incidence of cracked and shell-less eggs increased with supplementation. Profits were not significantly influenced, though there was a slight decrease. It is thought that the supplement may not havehad any effect, particularly after 61 weeks of age, from an economical point of view.
