The financial impact of an epizootic of transmissible gastroenteritis in pigs was evaluated in a California sow herd through estimating growth, feed, and profit functions. Two groups of pigs were studied: pigs born before and surviving the epizootic (epizootic [E] pigs), and pigs born after the epizootic (postepizootic [PE] pigs). Short-term profits were maximized at 165 days for both groups of pigs, ranging from $47.14 for female E pigs to $60.32 for male PE pigs. Accordingly, it was concluded that pigs surviving or born shortly after a transmissible gastroenteritis epizootic are profitable to raise, if raised under management conditions similar to those in the study herd.
通过估计生长、饲料和利润函数,在加利福尼亚的一个母猪群中评估了猪传染性胃肠炎流行的经济影响。研究了两组猪:在疫情爆发前出生并在疫情中存活下来的猪(疫情期 [E] 猪),以及疫情爆发后出生的猪(疫情后期 [PE] 猪)。两组猪的短期利润在165天时达到最大化,雌性E猪为47.14美元,雄性PE猪为60.32美元。因此得出结论,如果在与研究猪群相似的管理条件下饲养,在传染性胃肠炎疫情中存活或在疫情后不久出生的猪饲养起来是有利可图的。
