Improving performance of heat-stressed layers

Trials involving heat-stressed layers yielded the following results: Heat-stressed layers 61 to 80 (Trial 1) and 18 to 65 (Trial 2) weeks of age increased egg production by 1.71 and 0.73%, respectively, when fed zinc and manganese from Availa®Z/M. Under heat-stressed situations, layers fed zinc and manganese from Availa-Z/M consistently yielded heavier eggs. Heat-stressed layers fed zinc and manganese from Availa-Z/M produced 1.55 and 0.66 grams of extra egg mass during weeks 61 to 80 and 18 to 65, respectively. Feed efficiency of layers continued to improve under heat-stress situations when fed zinc and manganese from Availa-Z/M. Improvements of 2.25 and 1.63% were seen in Trials 1 and 2, respectively. Eggshell quality, as determined by specific gravity and shell thickness, was improved for layers reared under high ambient temperature environments when fed zinc and manganese from Availa-Z/M.
