Milk from the cows on this diet contains the same nutri ents fat, nonfat solids, sug ar, and proteins as milk from cows on normal feed. Altogether, six cows were on the test. Their milk yield reaches nearly the average level of Ayrshire cows in Scandinavian countries. Their calves are normal, and meat from the calves is of quality equal to that of cows on nor mal feeding. The calves them selves have been fed the ar 14 TEST COW FEED This feed has a course granular texture. It's ideal as an all purpose herd feed to be fed as it comes from the bag to milking cows, dry cows, calves, and bulls. Remember, it is EXCELLENT FOR FEEDING DURING WARM PERIODS.

Virtanen says, "Our studies have shown that the most im portant flavor compounds of milk are formed in the cow.” He is determining to what ex tent milk flavors come from synthesis within the cow and ttf what extent they come from feed. “Milk flavors can be classified into two groups: those transferred from feed to milk by way of the diges tive route qf the cow and those which -are formed in the cow in .the rumen and in the liver or mammary gland— from carbohydrates, amino or fatty acids, -and other chemi cal compounds in the feed,” the scientist says. Previous experiments in the United States and other coun- Rsm r See These Dealers For Your Feeds Lititz tries and In his own labora tory had convinced Virtanen that it would be possible to develop in cows, by gradually changing their feed, a rumen microbial population capable, to a greater degree than nor mal, of using nitrogen fiom urea and ammonium to syn thesize the essential ammo acids which are the chief com ponents of protein. He has now proved this to be true. Cows in his trials had their normal feed gradually taken away from them and the ar tificial feed gradually added while they were dry or becom ing dry. As the experiment has gone on, Virtanen has increased the daily poition of nitrogen in the feed. As he has done so, milk production has increased Rose Heistond Bros. Elizabethtown A. L. Herr & Bro.

Here is the feed you need for your herd! Today’s dairy farmers need a high energy feed vitamin-fortified and palatable to maintain the herd, encourage maximum milk produc tion, help produce calves, and be adaptable to milk parlor feeding. Yet, this feed must be free-flowing and easily handled . , . and return a good profit. RED ROSE 14 TEST-COW FEED is that kind of dairy feed. It’s made of high quality grains and proteins, high in fat, minerals, and digestible nutrients. Test-Cow Feed is very palatable, can be fed at all seasons, and is an excellent feed to keep appetites from lagging during warm days of summer. Chas. E. Sauder & Sons Terre Hill Ammon E.
