Show COW TESTING FOR BUTTER FAT (Contributed by LeRoy C. Funk,- Duchesue County Agent.) In a cow testing association the milk production from each cow is weighed for one 24 .hour period. This is done of course by weighing both the night and morning milk. From each milking a cample is taken. tak-en. The sample milk for testing should be cemjofled of proportionate proportion-ate par U from the xnilkJugs of one day. The cample ehonM fee taken immediately following the milking after the milk has been: mixed hr pouring from one bucket to another or by stirring up and down with a dipper. With IMs date one can readily determine the amount of fouttcrfat produced In- month, ac the one da ye production Is listed as average for the month. Thus, If a cow produces 20 pounds of milk for night and 20 pounds twelve tours later the total productions for the day is 40 pounds. With a thirty day month this would be a production of 1200 pounds of milk. Nov if the testing .is 3.5 per cent the amount of butter fat produced during the month would be 4 2 pounds. This is obtained by multiplying 1200 by 3.5 per cent. If the value of the butter but-ter 'fat is 40c per pound the total value of the cow's "production for the jwonth Is 16.80. Now if one . has a record of the feed coneamption for Lhe month it is eney to determine tho profit made during the month. .Where the oowe are fed together oae must -rtlmate the feed consumption.' Herd feeding of courseijg not as effective a individual indi-vidual deeding. Cow testing fie explained above is a neecMary ctep In dairy herd improvement, im-provement, and y dairy heard Improvement Im-provement we mean more profitable, production. Testing of a cow'e milk for butter-fat butter-fat has little value unices 'her milk is weighed regularly. Teeting aid weighing combined are necessary io determine production. iRecords and tests must continue for a full lactation lacta-tion period or for parts of two periods peri-ods covering a year to secure data J on the cow's worth. |
