HAENLEIN Cooperative Extension Dairy Specialist University of Delaware The custom fitting of milk and dairy products is not a conscious goal for most dairy farmers, at least not directly. Yet all efforts toward increasing profitability on the dairy farm indirectly take cus tom fitting into consideration. Custom fitting is simply what the consumer wants to buy, or what the milk producer is able to sell and tries to produce more of. If there is no demand for a certain product from the dairy farm, then there is no point in producing it The U.S. Holstein cow is proof that dairy farmers arc actually cus tom fitting to the consumer de mands. In the last 30 years, Hol stein cow’s milk has become the predominant cow’s milk in the United States, chosen over Jersey, Guernsey, Ayrshire. Brown Swiss and Milking Shorthorn cow’s milk. Holstein milk is naturally low in fat, lower than that of the other breeds. In recent years, as an incentive for dairy farmers to produce more of that content in milk that con sumers preferred, the U.S. dairy industry affixed a price differen tial or bonus for protein or solids not-fat or cheese yield content of milk. The debate about fat and cholesterol in milk has been going on for some time. The con sumer, meanwhile, has switched away from whole milk, opting in stead for low-fat 2 per cent, 1 percent or skim milk. This trend did not come from the farm dir ectly, but was prompted by milk processors of fering consumers a choice on the grocery shelf. Even in the pro cessing of milk for cheese, consumer inter est in low-fat products has had a considerable influence on newly available cheese varie ties The situation of American consumers offers an interesting comparison in the opposite direction to the nutritional needs of American dairy cows. Many Americans are not working as hard physically as they did 50 to 100 years ago, be fore the age of the auto mobile and mechaniza tion. Because they use less energy, they re quire less fat in their daily diets. American dairy cows, on the other hand, are working hard er physically. At 100 f pounds-milk yield per day, cows need much more energy, which is available only in the form of fat However, one fat is not equal to another fat Fat is a general term ap plied to a big family of different constituents with many different qualities and character istics. Another name for our food fats is “trigly ceride,” which explains that fat normally con sists of one part glycer ol and three parts fatty acids all hooked together. These fatty acids can be very different, there by making up different fat quali ties in the end. Fatty acids are so-called “satur ated” or “unsaturated” biochemi cally, which means differences in their actions in our body’s diges tion, metabolism and health, Fatty acids also have different lengths short, medium or long de pending on the number of atoms in their molecular chains. Research has cast unfavorable shadows over the saturated fatty acids, which are present in all fats and oils in varying amounts. Con sumers can read the nutrition label on products before picking the one they prefer. It is not that all satur ated fatty acids are bad; it is more a matter of how much one eats of them. And not all of these fatty acids are from fat in the diet. The body makes fat horn excess sugar and starch. Unsaturated fatty acids have re ceived positive attention in recent years from research, which bio chemically distinguishes between monounsaturated and polyun saturated fatty acids. It has been determined that while the body needs these unsaturated fatty acids, only a small amount is needed daily, much less than the typical daily intake by Americans.

Spraying Since 1961 Also, it has been found that the body needs much less of the poly unsaturated fatty acids than is cur rently being eaten. Their high lev el of consumption is actually de trimental to good health. I went to neighborhood food markets and checked the nutrition labels for contents of all available oils for mono- and polyunsatur ated fatty acids. This information is all there in plain English, but does anybody bother to read it? In talking to some of the store man agers, I found that few of them seem to know or care about what the differences mean. Assuming that you take the re search message seriously and that you want to custom fit your shop ping to buy high monounsaturated fatty acid contents rather than high polyunsaturated fatty acid con tents, which oils should you choose?

This in formation is not found on the nu trition labels. Does it matter? When you know what the differ ence means to your body, you will agree that it matters a lot.

Butter contains significant amounts of short- and medium chain length fatty acids - more than most other fat sources - and thus is a preferred fat source for people who do not want to gain body fat. Short- and medium weight chain fatty acids also have other well-documented anti microbial, anti-fungal and anti tumor properties. They have been used as treatment for digestive malabsorption, unthrifUness of children, to strengthen the im mune system and to lower choles terol contents and deposition in tissues. New South Dakota research published in the Journal of Dairy Science, July 1996, p. 1127-1136 and 1244-1249 shows that by changing the feeding of cows, you can custom-fit the fatty acid com position of milk and butter to suit the needs of the consumers better than before.
