On-Farm Utilization Of Precision Dairy Monitoring: Usefulness, Accuracy, And Affordability, Elizabeth A. Eckelkamp Jan 2018

On-Farm Utilization Of Precision Dairy Monitoring: Usefulness, Accuracy, And Affordability, Elizabeth A. Eckelkamp

Theses and Dissertations--Animal and Food Sciences

Precision dairy monitoring is used to supplement or replace human observation of dairy cattle. This study examined the value dairy producers placed on disease alerts generated from a precision dairy monitoring technology. A secondary objective was calculating the accuracy of technology-generated disease alerts compared against observed disease events. A final objective was determining the economic viability of investing in a precision dairy monitoring technology for detecting estrus and diseases.

A year-long observational study was conducted on four Kentucky dairy farms. All lactating dairy cows were equipped with a neck and leg tri-axial accelerometer. Technologies measured eating time, lying time, standing ...

Compost Bedded Pack Barns For Dairy Cattle: Bedding Performance And Mastitis As Compared To Sand Freestalls, Elizabeth A. Eckelkamp Jan 2014

Compost Bedded Pack Barns For Dairy Cattle: Bedding Performance And Mastitis As Compared To Sand Freestalls, Elizabeth A. Eckelkamp

Theses and Dissertations--Animal and Food Sciences

Lameness and mastitis are the two most costly diseases in the dairy industry. Reduction of these diseases through housing and management is beneficial. Compost bedded pack (CBP) and sand freestall barns were compared in a long-term, on-farm study to assess the effect of housing on each disease. Another research objective was to evaluate the effects of ambient weather conditions on moisture and 20 cm internal temperature of CBP. Compost bedded pack moisture, C:N ratio, and internal temperature effects on cleanliness, mastitis, and bedding bacterial counts were also considered. The last research objective was to evaluate the economics of bedding ...

A Detailed Investigation Of The Sociological, Economic, And Ecological Aspects Of Proposed Reservoir Sites In The Salt River Basin Of Kentucky, Stuart E. Neff, Louis A. Krumholz, John R. Baker, Daryl E. Jennings, Andrew C. Miller, Jerry S. Parsons, Vincent H. Resh, David S. White Nov 1973

A Detailed Investigation Of The Sociological, Economic, And Ecological Aspects Of Proposed Reservoir Sites In The Salt River Basin Of Kentucky, Stuart E. Neff, Louis A. Krumholz, John R. Baker, Daryl E. Jennings, Andrew C. Miller, Jerry S. Parsons, Vincent H. Resh, David S. White

KWRRI Research Reports

Samples of water, bottom fauna, and fishes were collected from 66 stations in the Salt River and one of its principal tributaries, the Beech Fork and its tributary, the Chaplin River, Kentucky. Precipitation ranged from 38.86 inches (1969) to 58.04 inches (1970), an increase of nearly 50 percent with marked fluctuations in discharge. Intensive comparisons of phosphates, sulfates, specific conductance, total alkalinity, total hardness, and turbidity showed the streams to be relatively clean and healthy. Nearly 300 different kinds of benthic organisms and other macroinvertebrates have been collected and identified from the basin. Detailed studies of caddisflies and ...
