Reconstruction and Validation of the Integrated Diagnostic SystEm for DAiry Cow WeLfare (IDEAL) to Assess Real-time Animal Well-being on Confined and Grazing Dairy Farms

Creator:: Krueger, Angela K.
Abstract:: Animal welfare is an essential component of agricultural production and animal use in teaching and research. However, defining animal welfare is intrinsically difficult because of how history and societal values and perceptions have shaped the term. Animal welfare encompasses three main ideas: physical well-being, normal affective/emotional states, and the ability...

Interrelationships among characteristics of body form and milk production in dairy cattle

Creator:: Ufford, Glen Raymond
Abstract:: Evaluations of body form and measures of milk production were recorded for 188 Holstein lactations and 77 Jersey lactations in the Oregon State University Dairy Herds. Components of body form included general appearance, dairy character, body capacity, and mammary system and 34 sub-components of these four traits plus body weight...

The role of phosphoenolpyruvate carboxykinase in the periparturient and ketotic dairy cow

Creator:: Duncan, Jennifer S.
Abstract:: Although the occurrence of ketosis is a postpartum phenomenon, recent studies have focused on the prepartum period as key in the development of the disorder. Indicators of prepartum energy status, such as depressed dry matter intake (DMI) and elevated plasma non-esterified fatty acid (NEFA) concentrations have been associated with the...

Performance of dairy cattle under two feeding regimes, dry lot and irrigated pasture

Creator:: Kyeyune-Sendagi, Aloysius Lloyd
Abstract:: Four experiments were conducted (1961-1964) for the primary purpose of studying the milk and milk constituent yields of dairy cows under dry lot and pasture systems of management. The secondary purpose was to compare the health and breeding performance of cows under these two systems. Ninety-eight cows of the Holstein...

Comparative values of corn and corn cannery waste silages for milk production in dairy cattle

Creator:: Meyers, George Henry
Abstract:: The production level of dairy cows fed corn cannery waste silage was investigated during a 305 day lactation study. Eighteen Holstein cows were paired according to their probable producing ability and field corn silage was fed to the control pairmates, Forage analyses (DM, CP, CF, and nitrates) were determined on...

The effects of various levels of dietary protein on high producing dairy cows in early lactation

Creator:: Pangborn, Marvin Clark
Abstract:: This project was designed to test the biological effects of three levels of dietary protein (12.7, 16.3 and 19.3% CP on a dry matter basis) on high producing Holstein-Friesian dairy cows. Forty five second lactation or older cows that showed the potential to produce over 31.75 kg (70 lbs) per...

The Effects of Prostaglandin F2α on Reproductive Performance in the Postpartum Dairy Cow and the Mechanism Behind its Benefits

Creator:: Younger, Kathryn Genevieve
Abstract:: During the beginning of the postpartum period, 80 to 100% of lactating dairy cows have bacterial contamination within their uteri. Presence of uterine bacteria may contribute to increased number of days open and services per conception within these cows. Expulsion of uterine contamination is crucial for uterine involution and reproductive...
