THE DAIRY INDUSTRY.

HOLSTEINS. 1 In the dairy world, the records ol' the past arc of no use for the future. Every once in a while some new winner comes over the course that smashes the record of the best that have (rone before. Within the past few weeks, reports a Canadian paper, the “Nor’west Farmer,” two American Holstein cows have been making now world’s records. The first of these to attract attention was a New York cow called Pontiac Clothilde Do Kol 2nd. This cow* is owned by Stevens Pros. Co., of Liverpool, New York, and at the time of her test she broke all the established records for butter-fat production for periods of seven and thirty days. This cow, tested under the supervision of Cornell University, produced in 7 consecutive days GIG.HI) milk, containing 29.77G1b of butterfat, and in GO days, 2588.41 b of milk containing HG.2291b fat, the amount 'of fat for the week being 11,1 b in excess of anything before known. Cornell University estimates that the fat produced is equal to 31.731 b of the best commercial butter for the week and 135.61 b for the 30 days. Scarcely had Avoid been received about this wonderful record when word came that for a thirty-day performance it was easily put into second place by another Holstein cow not nearly so far aAvay. This was the six-year-old coav Fieterje Maid Ormsby, OAvnod by John B. Invin, of Wood- • lake Farm, Minneapolis. The test for this coav Avas made by the Minnesota Experiment Station, Professor A. L. Haecker having the test in charge. Professor Haecker says of her: — “The Holstein coav Peterje Maid Ormsby, has recently broken the Avorld’s 30-day record for butter production. She produced in thirty days 2,567.81 b of milk and 145.661 b of butter, Avhich is over eight pounds the best record made previously. The coav Avas milked four times each day and Avas under Avatch both day and 'night by the testers. Each milking Avas carefully Aveighed and tested for butter-fat. The ration of the coav Avas corn ensilage and roots Avith a grain mixture. The champion coav Avas six years of age Avlien she made the test, and as a three-year-old she also has a famous record.” CASEIN AND FAT. IN MILK OF COWS OF DIFFERENT BREEDS. The Ontario Agricultural College and Experimental Farm have in the past tAVO or three years been investigating the relative amounts of casein and fat in different cow’s milk belonging to the different breeds. In their 36th annual report the folloAving statements appear:— The average number of days milkpng per coavs during the period of testing Avas 221. The Ayrshires produced the greatest number of pounds of milk, fat and casein. . The highest average percentage of fat and casein in the milk by breeds Avas in that of the Jerseys. The average percentage of fat and casein for nine cows Avere respectively 3.96 and 2.38. The range in the percentages of fat and casein in individual coav’s milk for the period of the' test Avas from 3.41 to 4.83 for the fat and 1.94 to 2.68 for the casein. None of the Ayrshires shoAved such a Avide variation in percentages of fat and casein in their milk as did coavs representing the other lavo breeds. The percentage of fat and casein tends to increase quite markedly/ toAvards the end of the period of lactation. So far as avc can judge from the data on hand, the feed does not appear to affect the percentage of fat and casein in the milk. Lactation appears to bo a more important factor than cither feed or season of the year. The Jerseys produced 1.761 b of fat for each pound of casein in the milk, or .5611) of casein for each pound of fat. The Holsteins produced 1.631 b fat for each pound of casein in milk, or ,611 b casein for each pound of fat. The Ayrshires produced 1.591 b of fat for each pound casein in milk, or ,621 b casein for each pound fat in milk. NEW JERSEY RECORD. A year’s authenticated record of the yield of the Jersey coav, Warder’s Lady, OAvned by Hood Farm, Massachuscttes, shows that in 365 days she gave 8191 bof butter-fat. The test Avas confirmed by a representative of the Massachusetts Agricultural College. The coav Avas started on test at five years of ago, and for the first tAvelve months she milked 11,0831 b loz that tested 7021 b 3oz butter; average of butter-fat for year 5.532. One hundred and fifteen days after she came into milk again, and for the year gave 14,8201 b of milk that tested 9641 b 15oz of butter; average, 5.4301 b butter-fat. This made her tests in two consecutive years average 12,4511 b Boz milk and 78311) 9;,0z butter.
