一年以前，豬流行性腹瀉病毒爆發已接近頂峰，並導致了高水平的仔豬死亡率的，因此，極大地降低了豬被保留屠宰。經濟復甦的程度的事實，2015年的數字比，對於2013年3月1日走高，豬流行性腹瀉病毒爆發之前就開始強調。這反映了一個更大的母豬，以養殖豬數量增長2％，在今年3月，在不到600萬頭。此外，生產力得到了改善，並在最新一季度的產仔數是最大的上一年的時間記錄，雖然還是有點落後於長期趨勢。

US-Pedv

US pig herd largely recovered from PEDv

Latest figures from USDA’s hogs and pigs inventory show that the country’s pig herd on 1 March was 7% larger than a year earlier, at 65.9 million head.

A year before, the PEDv outbreak was close to its peak and had led to high levels of piglet mortality and, hence, a dramatic reduction in pigs being kept for slaughter. The extent of the recovery is emphasised by the fact that the 2015 figure is higher than that for 1 March 2013, before the PEDv outbreak began. This reflects a larger sow herd, with breeding pig numbers up 2% in the year to March, at just under 6 million head. In addition, productivity had improved and the litter size in the latest quarter was the largest on record for the time of year, although still somewhat behind the long-term trend.
