The Daily News MONDAY, AUGUST 9. PASTEURISATION.

I The result of the experiments carried out at Maugorei Dairy Factory by two of the Government Dairy instructors, Messrs. Pedersen and Thompson, proving that the fatal " turnipy" flavor in

butter .from herds fed on turnips is entirely lost if pasteurisation is resorted to, is certain to be received with the liveliest interest .by dairy farmers throughout this province. Not only b the obnoxious flavor removed, but tin quality of the butter is distinctly ini

proved, as the grading test abunuSintl; demonstrated. As a result of the experiments there should he more general adoption of pasteurisation by the dairy

factories of the province, for, besides ■ improving the quality of the produce throughout tile summer, rendering immune from disease the skim-milk supplied to calves and pigs, winter dairying may lie carried on on lines showing the highest margin of prolit—winter feeding from turnips and allied root crops. .Not the least important 01 tnese advantages is that, which ensures the non-transmis-sion of disease germs in skim milk to 1 the young stock. Last week 'the O'hief I Veterinarian profoundly impressed . the I Agricultural Conference witli the facts I lie placed before it relating to U I dreaded scourge tuberculosis. Kefercie I lias frequently been made to the matter | at the dairy conferences and m the I press, but the points have never been I set out so clearly before as was the I ease when Jlr. lleakes dealt with them. I It is an established fact that tubercuI lusin is very prevalent in the dairy herds I and pigs throughout the dominion, and llr. Ueakes made live suggestions which may be regarded us being immediately necessary as previ ulivo measures. The present system of weeding out and slaughtering affected animals should be continued. The farms should be divided, a so that each paddock could lie Kept 1 clear, of cattle for some months ill turn, I Cleanliness should be constantly obscrvI ed in tin- milking sheds and yards. The I fourth suggestion was that all separated milk should be pasteurised at dairy factories and creameries ncfore its removal ,by farmers for the pilose ot fcedim calves and pigs. The pension of gooi winter feed, both for cows and for youn;. stock was also recommended, thus cnab I ling them to maintain a high standard o: vitality, and giving them a bettei chalice of resisting infection. Jlr. Reakei attaches most importance to the pastcur isation of the separated milk. As t< the effectiveness of pasteurisation then can now he no question. In Denmark am in the American States of lowa nnc Jlinesota it has been made eoinpu.Mir by law, and splendid results have ful lowed. In this province, where udoptci it has proved in every way satisfac-torj more than justifying the expense of ii: stallation and working. Jlr. liviiKe told the conference that he knew ol on dairy factory where last year' the skin: milk was nut pasteurised, and the pel centiige. of diseased pigs fed upon i varied in different large batches siaugl tered from .")!) to 1011 per cent. Tni year the milk was healed, not tuorougl ly pasteurised, yet successive larg

batches of 'pigs kepi in ihc same pens, reared from the same slock under similar conditions as in the previous year, were killed without a single diseased animal being found, and among those batclies in which tubercular pigs were ■present, the highest percentage was 11. As n further instance he said lie could name two factories within three miles of each other, in one of which the byproduct, whey, is pasteurised, and at the oilier it is not. In the first case, a tubercular pig which has been ted upon whey is a rarity; in the other a huge purchaser who is under inspection will not buy the pigs at ail. on account of the number found diseased on slaughter. Such facts as these are sull'icient to prove that the use of raw skim-milk is lone of the most potent causes of the dissemination of tubercular disease, and there is convincing evidence of tin: ell'icaey of pasteurisation. In these circumstances it should lie made compulsory to so treat the by-products thai the danger of infection is reduced to .vanishing point. Hut the advantages of adopting the system should be so apparent, to the dairy companies that its universal adoption should not need to b e enforced by legislation.
