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...

Creator:: Ramsing, Erica M.
Abstract:: Yeast culture supplementation has been used to improve the health and performance of dairy cows for the last 25 years. To evaluate the effect of a Saccharomyces cerevisiae fermentation product (Diamond V Original XP™) on the health and production of peripartal Holstein cows, two research studies were conducted. The first...

Creator:: Shriver-Munsch, Christine M.
Abstract:: The transition period is a time of increased nutritional demands and risk to metabolic and infectious diseases in dairy cows due to a suppressed immune system. These problems lead to reproductive challenges, increased culling rates, and decreased milk production postpartum, which leads to decreased profits. Feeding yeast (Saccharomyces cerevisiae) or...

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...

Creator:: DuBay, Kristi M.
Abstract:: Interferon tau (IFN-τ) is the pregnancy recognition signal secreted by the trophectodermal cells of the developing bovine embryo that prevents luteolysis and maintains critical progesterone production. Recent evidence has suggested in addition to the mechanism of action identified in the uterus, there may be a direct effect of IFN-τ on...

Creator:: Cappellozza, Bruno Ieda
Abstract:: Three experiments compared ruminal, physiological, and performance responses of beef steers consuming hay ad libitum and receiving grain-based supplements with (CAM) or without (CO) inclusion of camelina meal. In Exp. 1, 9 steers fitted with ruminal cannulas received CAM (2.04 kg of DM/d) or CO (2.20 kg of DM/d). Steers...

Abstract:: Selenium (Se) is an essential micronutrient of sheep. Supplementation is especially important in young lambs in order to prevent Se-deficiency signs. In the United States, the FDA regulates Se supplementation to ruminant diets at a level of 0.3 mg/kg Se (as fed basis). Questions still exist regarding what chemical form...
