Abstract

This experiment was carried out to evaluate the effects of different sources of limestone with different particle sizes (fine, medium and large) on bone quality 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, 2 blocks and 4 replicates of 8 hens each. The feeding trial lasted 38 weeks. 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 bone characteristics were observed, but better strength bone when larger particles were used
