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...

Dairy Cattle Nutrition and its Effect on Production, Milk, and Human Health

Creator:: Swanson, Katherine L.
Abstract:: As the world population continues to grow we must look for smarter and more sustainable ways to feed everyone. Milk is the first food humans consume and is a good source of protein, fat, and carbohydrates. The following studies sought to determine the effect of feeding blackberry pomace as a...

Antioxidant Effects of Blackberry Pomace on the Health of Transition Dairy Cows

Creator:: Estenson, Kaelyn A.
Abstract:: Blackberry pomace (BBP), a byproduct from juice processing, is often disposed of in landfills. We propose BBP as an antioxidant-rich feed supplement for transition dairy cows. To explore the effects of BBP on antioxidant status, 24 multiparous dairy cows (5 Holstein and 19 Jersey) were assigned randomly to one of...

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...

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...

Identification of the plasminogen activator inhibitor produced by the day 14 bovine embryo

Creator:: Mendoza, Ruben
Abstract:: Day 12-14 bovine embryos produce urokinase-type plasminogen activator (uPA) and an uPA-plasminogen activator inhibitor (PAI) complex. The type of PAI, -1 or -2, in the complex has not been determined therefore the objective of this research was to identify the PAI produced by the Day 14 bovine embryo. In experiment...

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...

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...

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...

Effects of camelina meal supplementation on ruminal forage degradability, performance, and physiological responses of beef cattle

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...
