Abstract

This experiment was carried out to evaluate the effects of different dietetic sources of limestone with different particle sizes (fine, medium and large) on the performance, eggshell quality and bone status of laying hens. 192 Isa Babcock B 300 hens, 33 weeks of age, were allotted in a randomized block design with a total of 6 treatments, with 2 blocks and 4 replicates of 8 hens each. The feeding trial lasted 38 weeks, divided into 9 cycles of 28 days. The six experimental diets were: 1 - fine limestone Source 1; 2 - medium limestone Source 1; 3 - larger limestone Source 1; 4 - fine limestone Source 2; 5 - larger limestone Source 2; 6 - larger limestone Source 3. No negative effects on layer shell quality, but better shell quality, measured by specific gravity were observed when hens were fed with larger limestone particles
