Lactose Intolerance: An Overview Of The Facts And Their Implications, Noelle M. Yeo
Lactose Intolerance: An Overview Of The Facts And Their Implications, Noelle M. Yeo
Honors Theses
Lactose intolerance is often blamed for the symptoms such as bloating, diarrhea, gas, abdominal pain, and nausea, that ail many people. Patients often do not seek proper diagnosis from a physician and create their own treatment plans, severely restricting lactose intake, without professional guidance. Even those who do seek the care of a physician find that diagnosis is complicated by less-than ideal testing and confusion due to the symptoms common to many other conditions. The misconceptions and inability to confirm a diagnosis of lactose intolerance can cause nutrient deficiencies in these patients, as well as begin a pattern of unnecessary …

Economic Impact Of Stable Flies (Diptera: Muscidae) On Dairy And Beef Cattle Production, David B. Taylor, Roger D. Moon, Darrell R. Mark
Department of Agricultural Economics: Faculty Publications
Stable flies, Stomoxys calcitrans (L.), are among the most damaging arthropod pests of cattle worldwide. The last estimate of their economic impact on United States cattle production was published 20 yr ago and placed losses at $608 million. Subsequently, several studies of effects of stable flies on beef cattle weight gain and feed efficiency have been published, and stable flies have become increasingly recognized as pests of cattle on pasture and range. We analyzed published studies and developed yield-loss functions to relate stable fly infestation levels to cattle productivity, and then estimated the economic impact of stable flies on cattle …

Trends In Sandhill Crane Numbers In Eastern New Mexico, James B. Montgomery Jr.
Proceedings of the North American Crane Workshop
Following a 1980s decline in the number of cranes in the Bitter Lake National Wildlife Refuge area of the Pecos River Valley in eastern New Mexico, peak fall migration numbers increased from 5,640 in 1989-90 to 15,790 in 2003-04 and 13,650 in 2004-05. Concurrently, hectares of corn grown for silage to feed dairy cows increased from 1,781 in 1989 to 8,013 in 2003 and 7,325 in 2004. The population goals of the NM Department of Game and Fish are being met but a downturn in the dairy industry could result in a decline in crane numbers.

G05-1587 Understandng Effective Fiber In Rations For Dairy Cattle, Paul J. Kononoff
University of Nebraska-Lincoln Extension: Historical Materials
Fiber type, quality and length are key to herd health and production.
Fiber is a key component in dairy rations. When nutritionists are faced with herd challenges such as low milkfat tests, foot problems, or low feed conversions, ration fiber often is evaluated. Effective fiber depends on the type and amount of forages and nonforage fiber sources being fed, the particle size of those forages and the amount of available nonfiberous carbohydrates included in the diet.

G05-1582 How To Reduce Heat Stress In Dairy Cattle, Jeffrey F. Keown, Paul J. Kononoff, Richard J. Grant
University of Nebraska-Lincoln Extension: Historical Materials
Four ways to reduce heat stress and maintain production and fertility in dairy cattle.
Heat stress is one of the leading causes of decreased production and fertility in Nebrasks dairy cattle during summer months. These losses are apparent in the decreased amount of milk shipped, increased days open and decreased breedings per conception. Some heat stress is unavoidable, but effects can be minimized if certain management practices are followed.
G05-1583 How To Body Condition Score Dairy Animals, Jeffrey F. Keown
G05-1583 How To Body Condition Score Dairy Animals, Jeffrey F. Keown
University of Nebraska-Lincoln Extension: Historical Materials
Routinely scoring the body condition of dairy animals can help detect potential problems that might cause a decrease in milk production.
As the production level of a herd increases, body condition scoring becomes more important. A routine program for body condition scoring can help detect potential health problems before they significantly reduce milk production. A herd of cattle in good body condition will produce more, and will be less susceptible to metabolic disorders, disease, mastitis and reproductive problems. Underconditioned cows are subject to health problems, and overconditioned cows are subject to calving difficulties, fatty liver syndrome and possible death.

University of Nebraska-Lincoln Extension: Historical Materials
Position descriptions are essential. A detailed position, or job, description can help you as an employer identify and eliminate applicants who will not perform well on the job and gives you justifiable grounds for terminating an employee who does not perform the job satisfactorily.
On most dairy farms, employees can be grouped into three categories: herd managers, feeders or outdoor workers, and milkers. This extension circular discusses the description for each category, how to start the hiring process, and questions that may be asked during interviewing and after hiring for a position on the dairy farm.

G98-1358 Feeding To Maximize Protein And Fat, Rick J. Grant
University of Nebraska-Lincoln Extension: Historical Materials
This NebGuide describes feeding guidelines to increase milk fat and protein production.
Proper feeding management of dairy herds can both improve the economy of production and provide a healthier cow. To achieve these goals, producers must feed to increase production of milk with maximum levels of milk fat and protein.
Milk solids components include fat, protein, lactose and minerals. Normal values for milk fat range from 3.7 percent (Holstein) to 4.9 percent (Jersey); milk protein ranges from 3.1 percent (Holstein) to 3.8 percent (Jersey). Lactose is usually 4.6–4.8 percent for all breeds; minerals (ash) average .74 percent. Because current milk …

University of Nebraska-Lincoln Extension: Historical Materials
Effluent from the dairy milking center, including discharges from the milking parlor (manure, feed solids, hoof dirt) and milkhouse (bulk tank and pipeline rinse water and detergent used in cleaning), is commonly disposed of in a variety of ways. Milking center effluent offers several unique challenges due to the presence of: 1. Large volumes of contaminated water which can overwhelm soil absorption systems. 2. Milk solids and fats and manure solids which plug many systems. 3. Cleaning sanitizers which reduce bacterial breakdown of solids. When these systems fail, effluent will become a risk to surface and groundwater quality.
