Egg production records from last year's experiment (see POULTRY 82-3) showed that laying hens responded to an Aureomycin addition (100 g per ton of feed fed 1 week per 28-day period) after a 2-month adaptation period. The beneficial effect of the antibiotic remained consistent during the later stages of production up to the 14th period, which resulted in an overall significant increase of 1.2% (Table 1). Other parameters measured were not significantly influenced by the addition of Aureomycin to the oats-based layer diet.
