猪是猪蛔虫卵的主要宿主,草场施以含有活的猪蛔虫卵的粪肥时,可导致牛和绵羊感染猪蛔虫。为此,本文作者研究了猪蛔虫卵在不同条件下的存活率。 试验Ⅰ:在猪粪泥中,将含10000只猪蛔虫卵粪便的有孔塑料管,置于粪泥堆内1.2米深处,粪堆的温度为10—17℃,pH平均为7.7。试验Ⅱ:在厌氧条件下,将含10ml水和250只猪蛔虫卵的平皿,置于15℃的Gaspak厌氧罐中。试验Ⅲ:在不同相对湿度(rH)条件下,将含沙和250只猪蛔虫卵的平皿,分别置于rH为100％,77.5％,47.5％,7.5％,温
Pigs are the main host for Ascaris suum eggs, which can cause the infection of Ascaris suum in cattle and sheep when used in the pasture with manure containing live Ascaris eggs. To this end, the authors studied the survival rate of Ascaris suum eggs under different conditions. Test I: In pig manure, a perforated plastic tube containing 10,000 pigs of Ascaris suum eggs was placed in a dredger at a depth of 1.2 meters. The temperature of the dunnage was 10-17 ° C and the average pH was 7.7. Test II: Under anaerobic conditions, a plate containing 10 ml water and 250 Ascaris suum eggs was placed in a Gaspak anaerobic tank at 15 ° C. Experiment III: Plates containing 250 eggs and Ascaris suum were placed in rH 100%, 77.5%, 47.5%, 7.5%, respectively under different relative humidity (rH) conditions
