Show INFLUENCE COLOR CF BUTTER Markets Demand Yellow Tint Which Is Supplied by Use of Dyes or Character of Cow's Feed. Although it is a fact that some dairy breeds give yellower milk than- others, even though it may be no richer in fat, the thing of greatest influence in color is the kind of feed the cows are getting. Market demands call for a yellow butter, which is supplied in the creamery by the use of certain harmless vegetable dyes, the use of which dairy laws rightly permit. The color also can be fed into the milk and make the use of dyes unnecessary. un-necessary. Carrots, for example, color milk and cream quickly. One of the natural coloring materials in milk and butter is called carotin, from carrots, and this material is found in many food materials. It is plentiful in fresh green grass, hence the milk colors up well in early spring. Alfalfa hay, cured to have a bright green color, contains good suplies of carotin, which appears in the cream as a result. Hay which has lost this green color, dry corn fodder, silage, straw, yellow yel-low corn and white, wheat, wheat bran, cottonseed meal and other milled feeds contain practically ncne, and cream from cows so fed will produce a light colored butter unless artificial coloring is supplied. The color adds nothing to the value or digestibility of butter, save in one's mind, but the market demands a yellow butter all the year round ar.d the color rr.vst either be supplied in the feed or in the creamery. |
