An attempt was made to study the influence of housing, management, and breed on the incidence of pneumonia in lambs. In experiment 1, four lots of lambs were housed either in closed or open-door pens, with or without brooders, and a fifth lot was subjected to close housing alternated with chiling. Of the lambs in the chilled group, 27% had extensive pneumonic lesions when slaughtered compared with between 37 and 38% in the other four groups. How-ever, early mortality was 33% in the former as apposed to but 9% in the other four groups. there was half as much pneumonia in lambs that developed well enough to be slaughtered in August as compared with lambs of similar age slaughtered in October. In experiment 2, in lots 6 through 13, the association between breedsand infant mortality or pneumonia was not significant. Of the creep-fed lambs, 75% had pneumonic lesions while only 53% of the non-creep-fed lambs had similar lesions. There was a gradual ascending incidence of pneumonic lesions in lambs born from the first week of February to the first week of Abril. |
