Caseous Lymphadenitis : Relative to caseous lymphadenitis, the annual report of the officer in charge of the Veterinary Laboratory, Wallaceville, states : “ While the South Island flocks under trial showed a considerable reduction in numbers affected down to the vicinity of 2 per cent, below which it is difficult to reduce the disease, the North Island flock under investigation has risen from last year’s 2-7 per cent, almost to its first-flock percentage of just over 3 per cent. There has been a change in glands affected in the North Island flock, for the majority of the abscesses palpated this year have been found in the supramammary glands. This fact, taken in conjunction with a very much lessened incidence of caseous lymphadenitis in dry ewes, suggests that two factors operating in the North Island flocks under observation are of greater importance than the shearing factor. These are crutching and lamb carriage of the disease from ewe to ewe by mismothering at docking. Crutching wounds must become infected in places other than yards and sheds, and possibly in the more heavily stocked areas some consideration must be given to sheep night camps.”
