The time of survival of Salmonella typhimurium, coccidia oocysts and ascaris eggs in manure of layer was determined in 5 different housing systems and 2 storing places for litter. The experiments were carried out in a stable of experimental station Frankenforst of the university of Bonn with a flock of 2200 hens. The effects of the environment conditions temperature, dry matter content, pH-value and intestinal microflora of the manure have also been studied. The time of survival was different depending on the housing system. A recovery of viable coccidia oocysts was possible after 13-370 days, ascaris eggs 53-347 days and Salmonella typhimurium 2-175 days. The tenacity of the investigated test organism mainly depend on the dry matter content of the manure. The longest period of survival of salmonellas was found in dry environment conditions, were as coccidia oocysts and ascaris eggs have been observed with the shortest period of survival. The possibility of the examined resistant parasite stages to develop was disturbed. Only few of them were able to develop and with a longer development time than those examined in the control suspension. The results of this study indicate that chicken manure, before using it in plant production, should be stored long enough to prevent men or animals from possible infections.
在5种不同的饲养系统和2个垫料储存场所,测定了鼠伤寒沙门氏菌、球虫卵囊和蛔虫卵在蛋鸡粪便中的存活时间。实验在波恩大学弗兰肯福斯特实验站的一个鸡舍中进行,鸡群数量为2200只母鸡。还研究了环境条件(温度、干物质含量、pH值)和粪便肠道微生物群的影响。存活时间因饲养系统而异。13 - 370天后可检测到活的球虫卵囊,53 - 347天后可检测到蛔虫卵,2 - 175天后可检测到鼠伤寒沙门氏菌。所研究的受试生物体的存活能力主要取决于粪便的干物质含量。沙门氏菌在干燥环境条件下存活时间最长,而球虫卵囊和蛔虫卵的存活时间最短。所检测的抗性寄生虫阶段的发育可能性受到干扰。只有少数能够发育,且发育时间比在对照悬液中检测的更长。本研究结果表明,鸡粪在用于植物生产之前,应储存足够长的时间,以防止人类或动物受到可能的感染。
