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...

The effect of prepartum anionic diets on cortisol, adiponectin, and tumour necrosis factor-α expression at varying levels of body mass index in preparturient dairy cows: implications for insulin resistance

Creator:: Puntenney, Steven B.
Abstract:: Twenty-six Holstein and 18 Jersey multiparous cows in a randomized block design were assigned by calving date and breed to a non-anionic prepartum diet (CTRL) or a treatment diet containing a commercial anionic salt supplement (Animate®). Control and treatment diets were formulated to a dietary anion-cation difference (DCAD) of 21.3...

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...

Expression of the Ets family of transcription factors in early bovine and ovine embryo development

Creator:: Collins, Jonna Erin
Abstract:: Maternally-derived transcripts and proteins support early bovine and ovine embryo development until the 8- to 16-cell stage, at which time embryonic transcripts become essential for continued development. One purported mechanism for the switch from maternal to zygotic control of development (maternal to zygotic genome activation; MZGA) is the appearance of...

Effect of prepartum anionic supplementation on periparturient feed intake and behavior, health and milk production

Creator:: DeGroot, Michael Alan
Abstract:: Our objectives were to determine if dietary cation-anion difference (DCAD) and source of anions influence periparturient feed intake and milk production, and to characterize feeding behavior of dairy cattle during the transition period. Diets differed in DCAD (cationic or anionic) and anionic supplement (BioChlor®, Fermenten®, or anionic salts), and were...

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...
