Effects of conjugated linoleic acids on PGE₂, PGF₂α and progesterone production by bovine luteal cells in vitro

Creator:: May, Katherine C. P.
Abstract:: Feeding conjugated linoleic acids (CLA) improves reproductive performance in dairy cows; however, the molecular mechanisms by which CLA improves reproduction are not well understood. Therefore, we evaluated whether the CLA isomers, trans-10, cis-12 CLA and cis-9, trans-11 CLA altered synthesis of steroidogenic hormones in bovine luteal cells by measuring concentrations...

Perennial ryegrass nonstructural carbohydrates in dairy cattle nutrition

Creator:: Buyserie, Annette C.
Abstract:: Ruminal microorganisms require nitrogen and energy for microbial crude protein (MCP) synthesis. High-quality grass provides an excess of readily available proteins relative to available carbohydrates which reduces the conversion efficiency of grass protein to MCP. Nonstructural carbohydrates (NSC) are the primary source of readily available energy. Objectives of trial 1...

Improving the nutritional and textural properties of dairy products by feeding Holstein cows processed flaxseed

Creator:: Oeffner, Scott P.
Abstract:: There is growing public concern about the high proportion of saturated fatty acids in milk fat; however, feed intake, energy partitioning toward milk synthesis, and milk fat concentrations can decrease when cows are fed high concentrations of unsaturated lipids. The objective of this study was to identify the optimal rate...

Effects of prostaglandin F2alpha on neutrophil populations, uterine health and reproductive performance in dairy cows, Effects of prostaglandin F₂α on neutrophil populations, uterine health and reproductive performance in dairy cows

Creator:: Lulay, Adrienne McCracken
Abstract:: Incidences of uterine infections in dairy cattle are high between parturition and Day 21 postpartum. Dairy cows with uterine infections are at risk for prolonged periods of days open and multiple services before becoming pregnant. Neutrophils are the first wave of immune system defense against uterine contamination. Neutrophil function seems...

Assessing the phosphorus and potassium balances in Oregon's dairies

Creator:: Higgs, Kathryn N.
Abstract:: A field study was conducted to assess phosphorus (P) and potassium (K) concentrations of both lactating and dry cow diets on Oregon's dairies. Thirty-seven dairy farms, located in western Oregon, were grouped according to geographic region, valley (V) or coast (C), and herd size, small (S) or large (L). Farms...

Salmonella and other Enterobacteriaceae in dairy cow feed ingredients and their antimicrobial resistance

Creator:: Kidd, Riam S.
Abstract:: Antimicrobial resistant Enterobacteriaceae might be introduced into dairy cows through the consumption of feeds and the microbes may eventually enter the human food supply. Thirty-two farms were selected at random from 43 commodity feeding dairy farms. Of the 32 farms selected, 12 farms agreed to participate in the study. In...

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...
