Drugs may be used with laying hens. A tranquilizer, used in conjunction with antibiotics in layer feed, was advertised as boosting egg production since it “calms birds, reduces blood pressure and heart rate, increases respiratory rate.” Experimentally, hens fed aspirin laid more eggs. Another drug has been found to be effective in reducing “laying slump”; at the same time it cuts feeding costs.

'''Poultry-Arsenic'''

 

Since 1950, small amounts of arsenic as arsanilic acid have been incorporated into poultry feed to stimulate early maturation, increase efficiency of feed utilization, produce more eggs, “improve” skin coloring and feathering, and yield more profits.
