Abstract

In the range of 456-5,518 pigs delivered to slaughter per farm per year, herd size appeared to have no real influence on either the percentage of pigs culled during the finishing period or the percentage of pigs with lesions at slaughter. Percentage of pigs culled during the finishing period is positively correlated with percentage of pigs with lesions of slaughter P less than 0.01. The frequency of pigs culled during the finishing period could be an indicator for the need of intervention to restore health.

摘要

在每个农场每年交付屠宰的456 - 5518头猪的范围内，猪群规模似乎对育肥期淘汰猪的百分比或屠宰时出现病变的猪的百分比均无实际影响。育肥期淘汰猪的百分比与屠宰时出现病变的猪的百分比呈正相关（P < 0.01）。育肥期淘汰猪的频率可能是需要采取干预措施来恢复健康的一个指标。
