Free Fatty Acids Associated With Induced Rancidity In Cream And Butter, John Alan Anderson
Free Fatty Acids Associated With Induced Rancidity In Cream And Butter, John Alan Anderson
Electronic Theses and Dissertations
One of the most significant problems in the dairy industry today is the flavor defect known as rancidity. This defect has been recognized for some time, but recent trends in milk handling have increased the problem of rancidity. Recently the dairy industry on the farm has changed to the increased use of pipeline milkers and bulk handling of milk. Processing plants are becoming larger and more centralized, resulting in more movement over longer distances for the raw product. These changes result in increased foaming and agitation of the milk, contributing to the rancidity problem. The butter industry has changed. Butter …
Detection Of Antibiotic Residues In Bovine Milk, Mark Edward Johnson
Detection Of Antibiotic Residues In Bovine Milk, Mark Edward Johnson
Electronic Theses and Dissertations
Under the Food, Drug, and Cosmetic Act antibiotics are considered as ·adulterants in milk and milk products. Cultured dairy products cannot be made with milk containing small concentrations -of antibiotics. Also, minute quantities of antibiotics cause allergic reactions in some people. Penicillin is the most common antibiotic to which people are allergic, and penicillin is also the most commonly used antibiotic in the treatment of infections in bovines. Antibiotics, whether injected intravenously or intramuscularly, or infused into the udder of the cow, can be secreted into the milk. It is for this reason that withdrawal times for milk from cows …
Intake And Digestibility Of Brown-Midrib Corn Silage By Lactating Dairy Cows, James Allen Rook
Intake And Digestibility Of Brown-Midrib Corn Silage By Lactating Dairy Cows, James Allen Rook
Electronic Theses and Dissertations
Two short-term trials evaluated brown-midrib-3 (bm3) mutant (low lignin) corn silage for early lactation Holstein cows. In trial 1, five cows per group were individually fed a ration of silage and grain (60:40 ratio, dry matter basis) from week 2 through 8 of lactation. Lignin percentages for bm3 and normal silages were 4.9 and 6.4. Cattle fed the bm3 ration consumed 19% more total dry matter as percent of body weight than cows fed normal. Digestibilities of dry matter, cell-wall contents, acid detergent fiber, and energy were 3 to percentage units higher for the bm3 …
A Study Of Milk Composition In South Dakota, Jeng-Jung Yee
A Study Of Milk Composition In South Dakota, Jeng-Jung Yee
Electronic Theses and Dissertations
The composition of cow's milk, including both the fat and solids-not-fat (SNF) content, is known to vary over rather broad ranges. Breed and individuality of the cow are the major factors influencing this, but many other factors are known to exert their influence. However, it has generally been observed that compensation or complementing occurs when the milk of cows is mixed together; so that the composition of milk from a herd will tend toward averages or norms. This effect usually is even more marked as the milk from two or more herds is commingled. Payment for milk on the basis …
