Technical Abstract: Three trials were conducted in which 10-week-old layer chicks were eyedrop inoculated with broth cultures of Mycoplasma gallinarum and maintained in biological isolation units through 60 weeks of age. Within each trial, egg production was recorded daily, and egg weight was determined for four days of each week throughout the trials. For each 28-day period, hen weight, egg size distribution, and feed consumption per dozen eggs were determined. No significant difference (P < 0.05) was observed between the treatments for average hen day egg production across the three trials. No significant differences were observed for any of the nine test intervals for average hen or egg weight. No significant differences were noted for egg size distribution.
