Treatment of feedyard dust containing endotoxin and its effect on weanling goats

摘要: Forty-two, mixed-sex, weanling goats were randomly allotted to six treatment groups: principal autoclaved dust ( n = 6), control non-autoclaved (n dry-heat and non-dry-heat 6). Principals treated with appropriate for one 4 h in a closed tent. The data from the group 9) non-dust recorded after prior start of present study. endotoxin (ET) concentrations determined (13.3g ET/g), dry-heated (0.173g non-treated 26.9g ET/g. tent aerosolized were: 0.369 g/(m 3 min) 4.904g ET/(m min); 0.347 0.0015g 0.539 min). These ET aerosol caused autoclave goat significantly increase their rectal temperatures at 4, 8 total white blood cells (WBCs) increased 12 24 compared respective groups. concentration did not induce an mean temperature response or WBC count. Of three products only contained viable microbes. Published by Elsevier Science B.V.
