THE DAIRY INDUSTRY.

PASTEURIZATION OF SKIMMILK AND WHEY.

With regard to the pasteurization of the by-products at' dairy factories, the Director of Dairy-produce reports that a very large number have adopted this treatment as applied to whey, and possibly double the number will be following this course as compared with last year. The benefits derived from it are many, and seem to appeal to farmers. Slower progress, however, is being made with the pasteurization of skimmilk, and, while a few are adopting it, many others are delaying the installation of the necessary plant in the meantime, as skim-milk presents more difficulties in treatment than whey, both as regards the cost of the plant needed for the purpose and the effect of the process on the milk. A start has been, made at the Glen Oroita Factory with the plant which was installed by the Department some time ago, and by an arrangement with the Director of Live-Stock and Meat, one of his officers has been placed in charge of the work, together with the supervision of the pigs and calves which are being fed on the product. The whole of the skim-milk is being treated daily, to the evident satisfaction of both the directors and the suppliers. When the season is over, some very valuable data should be available regarding the effect of feeding this milk to farm-stock.
