Improving Performance Of Heat-stressed Layers

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.
