title: [The tenacity of Newcastle disease virus (LaSota) in the excrement of laying hens in different housing systems].
abstract: The survival time of NDV (LaSota) in the excrement of layers was in summer (winter) 22 and 18 days (26 and 36 days) in two cage houses, 14 and 18 days (36 and 33 days) in two floor-pen houses, as well as 8 days (54 and 68 days) in two dropping store places. By one week staying in battery cages and following the storage in dropping store place after 47 or 50 days NDV (LaSota) could not be reisolated. Besides environment factors, temperature, pH and dry matter was the thermic effect very significant. The comparison of the tenacity of NDV (LaSota) in different housing systems was besides of the quantitative determination of survival time supported through the application of a life time distribution test.
