CALIFORNIA NATIONAL ANIMAL HEALTH MONITORING-SYSTEM FOR MEAT TURKEY FLOCKS - 1988-89 PILOT-STUDY - MANAGEMENT-PRACTICES, FLOCK HEALTH, AND PRODUCTION

A pilot project for a meat turkey National Animal Health Monitoring Sy stem was undertaken in California in 1988-89 to explore data gathering techniques and to estimate the frequency, magnitude, and variability of management, flock health (including administration of pharmaceutica ls for prevention and treatment of disease), and production variables in order to facilitate planning for future food animal monitoring syst ems. Enteritis, which occurred in over one-third of the flocks, and co libacillosis, which occurred in nearly one-quarter of flocks, were the most common diseases reported. Mycoplasma synoviae was reported in tw o flocks and Myroplasma gallisepticum and Mycoplasma meleagridis each were reported in one flock. Total mortality rate in the sample flocks was 9.0% (95% confidence interval [Cl] 8.2%-9.8%). The tom-specific mo rtality rate was 10.3% (95% Cl 9.8%-12.1%)and the hen-specific mortali ty race was 6.6% (95% Cl 5.7%-7.4%).
