Evaluation of triticale grain in high producing dairy cow rations

Creator:: Biedenbach, Robert L.
Abstract:: The objective of this study was to evaluate triticale grain fed as a concentrate in the diet of high producing dairy cows. A lactation study, in vitro dry matter digestibilities and a preliminary physiological effects trial were conducted to evaluate triticale and used to make feeding recommendations. In the lactation...

Transforming shrimp and crab waste into dairy heifer feed

Creator:: Evers, Dale J.
Abstract:: The goal of these experiments was to ensile combinations of shrimp or crab waste with perennial ryegrass straw and analyze it for silage quality and ruminal degradability. The rapid deterioration of seafood wastes required initial preservation prior to ensiling to minimize odor production and protein breakdown. Eight experiments were conducted...

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...

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...

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...

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...

Hemorrhagic bowel syndrome in dairy cattle and efficacy of feed additive in stimulating immune response in livestock

Creator:: Wang, Yong-Qiang
Abstract:: Hemorrhagic bowel syndrome (HBS) is a devastating disorder affecting high producing dairy cattle. As an important emerging disease (Animal and Plant Health Inspection Service, 2003), HBS is now estimated to account for > 2% of the deaths of dairy cattle (Kirkpatrick et al, 2001). However, little is known about 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...

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...
