Show Test Cream Separators, Is Advice of Expert Cream separators that have not been tested for some time may be cheating their owners out of a considerable con-siderable sum every week. That can be avoided, for skim milk testing will reveal the honesty of the most deceitful de-ceitful separator, according to C. A. verson of the Iowa state college. "Surprising results have been obtained ob-tained wherever fairly large numbers of band separators have been tested," Mr. Iverson says. "In Worth county, five separators in one cow-testing association as-sociation were found to be losing excessive ex-cessive amount of butterfat. We feel certain that there are many separators separa-tors in every community that are losing los-ing butterfat for their owners. An annual loss of several dol-ars can easily result if the machine is not regulated or run properly. Skim milk testing can be done by the Babcock method with a special double-necked test bottle. In place of the 17.5 cubic centimeters of acid required re-quired for whole milk, 20 are used for skim milk. Otherwise, practically the same procedure is followed as in testing test-ing wdiole milk. The test can be made bj the farmers themselves, or, if this is not convenient, by the local . creamery. |
