Influence Of Winter Housing Conditions On Growth Rates And Feed Consumption Of Dairy Heifers, Emery H. Bartle Jan 1950

Influence Of Winter Housing Conditions On Growth Rates And Feed Consumption Of Dairy Heifers, Emery H. Bartle

Electronic Theses and Dissertations

It is important in dairy cattle management to maintain steady and continuous growth of heifers and thereby secure properly developed cows which will give the production that is expected of them when they are brought into the milking herd. In general, heifer calves during the first twelve months of their growing period are carefully managed as to feed, housing and care to promote normal growth. However, they are often neglected during their yearling stage to the point where growth is retarded because of environment factors. On many dairy farms in the North Central States the management of yearling dairy heifers …


The Efficiency Of Churn Washing Method And The Keeping Quality Of Butter As Indicated By Yeast And Mold Counts, T. Allen Evans Jan 1939

The Efficiency Of Churn Washing Method And The Keeping Quality Of Butter As Indicated By Yeast And Mold Counts, T. Allen Evans

Electronic Theses and Dissertations

Of all the equipment used in the manufacture of butter, no single piece has as close contact with the finished product as does the churn while at the same time no piece of equipment is more difficult to keep properly cleaned. The workers in the dairy industry have expended much time and effort attempting to build a churn which could be kept in a more satisfactory state, especially from a bacteriological point of view. As yet no satisfactory material for churn construction has been found to replace wood which at best is difficult to keep free of micro-organisms. Since it …

The Influence Of Feed And Sunshine On The Vitamin D Content Of Cow’S Milk, Ben L. Robinson

Electronic Theses and Dissertations

For the past several years there has been a growing tendency among dairymen, particularity those located near the large cities, to keep their cows in the barn much of the time. Under such a system of management the cows receive but little direct sunshine. In some localities it is also possible to find many cows which are fed the year around on dry feed receiving very little, if any, green food, either as soiling crops or as pasture. From many standpoints such practices are, of course, necessary and desirable, but from the standpoint of the nutritional value of the milk …
