A pilot project for a meat turkey National Animal Health Monitoring System 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 pharmaceuticals for prevention and treatment of disease), and production variables in order to facilitate planning for future food animal monitoring systems. Enteritis, which occurred in over one-third of the flocks, and colibacillosis, which occurred in nearly one-quarter of flocks, were the most common diseases reported. Mycoplasma synoviae was reported in two flocks and Mycoplasma gallisepticum and Mycoplasma meleagridis each were reported in one flock. Total mortality rate in the sample flocks was 9.0% (95% confidence interval [CI] 8.2%-9.8%). The tom-specific mortality rate was 10.9% (95% CI 9.8%-12.1%) and the hen-specific mortality rate was 6.6% (95% CI 5.7%-7.4%).
1988 - 1989年，在加利福尼亚开展了一项肉用火鸡国家动物健康监测系统的试点项目，以探索数据收集技术，并估计管理、禽群健康（包括用于疾病预防和治疗的药物管理）以及生产变量的频率、规模和变异性，以便为未来食用动物监测系统的规划提供便利。肠炎在超过三分之一的禽群中发生，大肠杆菌病在近四分之一的禽群中发生，是报告的最常见疾病。在两个禽群中报告了滑膜支原体，在一个禽群中分别报告了鸡毒支原体和火鸡支原体。样本禽群的总死亡率为9.0%（95%置信区间[CI] 8.2% - 9.8%）。公火鸡的死亡率为10.9%（95% CI 9.8% - 12.1%），母火鸡的死亡率为6.6%（95% CI 5.7% - 7.4%）。
