The Incidence Of Staphylococcus Aureus Mastitis In Maine Dairy Cattle, Morgan Belvin
The Incidence Of Staphylococcus Aureus Mastitis In Maine Dairy Cattle, Morgan Belvin
Honors College
This project investigated the factors surrounding the incidence of Staphylococcus aureus (SA) mastitis in Maine dairy cattle. This type of mastitis is driven by an antibiotic resistant pathogen that is very contagious among cattle, though farmers are often unaware of how common this type of mastitis is and that it could be present in their herds. My hypothesis was that specific farm factors, like milkers performing other tasks during milking, as well as the act of pre-dipping versus not pre-dipping, would explain the increase in SA mastitis. A thirty-seven-question IRB-approved survey was subsequently distributed to farmers in the University of …
Effects Of Probiotic Supplementation On Growth And Health Of Pre-Weaned Dairy Calves, Lily Bello
Effects Of Probiotic Supplementation On Growth And Health Of Pre-Weaned Dairy Calves, Lily Bello
Honors Scholar Theses
Dairy calf immune development leaves calves susceptible to illness during the pre-weaned stage of life. Previous studies have shown that the use of probiotics during this time may result in increased growth rates and decreased incidence of illness, particularly diarrhea and scours. We hypothesized that by providing probiotics during the time from birth until weaning, calves on study would experience similar growth and health benefits. Neonatal calves (N=32) were provided milk replacer three times daily, with half of the calves receiving Probios® supplements mixed in with their first morning feeding. Growth and health measurements were collected weekly. Probiotic administration significantly …
Monitoring Yogurt Culture Fermentation And Predicting Fermentation Endpoint With Fluorescence Spectroscopy, Timothey P. Mains, Frederick Alan Payne, Michael P. Sama
Monitoring Yogurt Culture Fermentation And Predicting Fermentation Endpoint With Fluorescence Spectroscopy, Timothey P. Mains, Frederick Alan Payne, Michael P. Sama
Biosystems and Agricultural Engineering Faculty Publications
Determination of the endpoint of yogurt culture fermentation is a process parameter that could benefit from automation. The feasibility of using a fluorescence sensor technology based on 280 nm excitation and 350 nm emission to predict the endpoint of yogurt culture fermentation was investigated and compared with the endpoint prediction from a near-infrared (880 nm) light backscatter sensor. Yogurt cultures with three levels of milk solids (8%, 10%, and 12%) and three temperatures (40°C, 43°C, and 46°C) were tested with three replications in a 3 x 3 factorial design (n = 27). Prediction models were developed for each optical measurement …
Economic Impact Of Stable Flies (Diptera: Muscidae) On Dairy And Beef Cattle Production, David B. Taylor, Roger D. Moon, Darrell R. Mark
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 …

An Accelerated Feeding Study For Dairy Beef Steers, D. R. Zobell
An Accelerated Feeding Study For Dairy Beef Steers, D. R. Zobell
All Archived Publications
A large number of Holstein bull (steer) calves are produced by the dairy industry. Producers who purchase these calves should understand that depending on the production strategy employed, the economic outcome could be quite broad. Dairy beef calves that are intensively managed, using aggressive feeding strategies to achieve high levels of efficiency, increase the opportunity for profitability.
Light Backscatter Of Milk Products For Transition Sensing Using Optical Fibers, Frederick A. Payne, Czarena L. Crofcheck, Sue E. Nokes, Klat C. Kang
Light Backscatter Of Milk Products For Transition Sensing Using Optical Fibers, Frederick A. Payne, Czarena L. Crofcheck, Sue E. Nokes, Klat C. Kang
Biosystems and Agricultural Engineering Faculty Publications
Transition sensors are needed, particularly in the dairy industry, for detecting transitions in pipe flow systems from product-to-water or product-to-product (such as from chocolate to vanilla ice cream mix). Transition information is used to automatically sequence valves to minimize product waste. Optical fibers were used to measure light backscatter between 400 and 950 nm as a function of milk concentration in water and milkfat concentration in milk. The normalized response (100% for product and 0% for water) as a function of product concentration in water was approximately logarithmic for skim milk between 400 and 900 nm and approximately linear for …
Judging Quality In Dairy Products, P. A. Downs
Judging Quality In Dairy Products, P. A. Downs
Nebraska Agricultural Experiment Station: Historical Circulars
In the dairy industry increasing attention is being paid to the question of quality of products. The well established system of buying and selling butter and cheese on the basis of quality by score or grade is practiced in the principal markets of the world. The other dairy products, while not marketed by score, are receiving more and more attention in this respect. As more information becomes available and the judging better standardized, other dairy products will doubtless be sold by grade.

Selection, Breeding, Methods Means More Milk, H. P. Davis
Selection, Breeding, Methods Means More Milk, H. P. Davis
Nebraska Agricultural Experiment Station: Historical Circulars
Milk good cows. It pays if you know how. Good dairy cows will always make money. Scrub, poor, or common cows never bring a good profit and usually cause a loss. Why waste feed and labor on inefficient producers, the kind that never make a satisfactory profit? Join a cow testing association. Let the tester keep books on your cows and let the milk scale and the milk sheet point out the money makers. Improvement comes only from selection and breeding.
Feeding The Dairy Cow, H. P. Davis
Feeding The Dairy Cow, H. P. Davis
Nebraska Agricultural Experiment Station: Historical Circulars
Cows produce milk from feed and water only. Therefore feed in proper quantity and quality is usually the limiting factor governing a cow's production up to the limit of her capacity.
Cooling Tanks And Milk Houses As Factors In Cream Improvement, J. H. Frandsen
Cooling Tanks And Milk Houses As Factors In Cream Improvement, J. H. Frandsen
Nebraska Agricultural Experiment Station: Historical Circulars
The dairymen of this country have suffered enormous losses due to the lower price received for poor butter. The present need is for a survey of the situation that shall result in a thoro understanding and cooperation of cream producers, creamery men, legislators, and educators.

Bulletin No. 57 - By-Products Of The Dairy, F. B. Linfield
UAES Bulletins
Soon after becoming connected with the Station, the writer, from observations made in various parts of the State, was impressed with the necessity for investigation looking to the profitable disposal of the by-products of the dairy, both at the factory and on the farm. The common method at the factories seemed to be to feed hogs on milk or whey alone, and where grain was fed, it was only given to finish the hog for market. This method of management did not appear to be successful, for it generally took the whole season to get one crop of hogs ready …
