The effect of nicotinic acid supplementation during late-gestation on lipolysis and feed intake during the transition period

Creator:: Chamberlain, Jason L.
Abstract:: An experiment was conducted with 27 multiparous Holstein and 27 multiparous Jersey cows to determine if nicotinic acid (NA) supplementation during the prepartum phase of the transition period decreases lipolysis and improves dry matter intake and to determine if Holstein and Jersey cows respond similarly to NA supplementation. Cows were...

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...

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...

Growth and carcass merit of purebred Jersey steer calves finished on grain-based diets at two different energy levels

Creator:: Tschida, Garrett L.
Abstract:: Purebred Jersey steers are often overlooked for beef production due to the perceived poor growth and production. Currently dairy persons marketing their steer offspring are receiving minimal compensation due to lack of demand by beef feeders and a saturated veal market. Twenty purebred Jersey steers were used to evaluate lifetime...

Puberty development and reproductive performance in beef heifers fed rations supplemented with Oregon by-product feeds

Creator:: Oswald, Keely E.
Abstract:: In the majority of management scenarios, it is imperative that beef replacement heifers calve at two years of age. In order to achieve this goal, yearling heifers should reach 60 to 65% of their mature body weight by 13 months of age. Feed costs represent 75 to 80% of the...

Daily vs alternate day supplementation of soybean meal or wheat middlings to steers consuming low quality hay

Creator:: Shirley, Tyson R.
Abstract:: Two experiments were conducted to determine the effects of daily (D) vs alternate day (AD) supplementation of soybean meal (SBM) or wheat middlings (WM) on forage organic matter intake (OMI), ruminal digesta kinetics, total tract digestibility, and ADG of steers consuming low quality forage. In Exp. 1, five Angus x...

Management of stockpiled forages and optimal use of supplements by beef cattle while consuming low-quality forages

Creator:: Suverly, Norman A.
Abstract:: Three studies were conducted to evaluate: 1) rotationally grazed forage for late-summer stockpiling; 2) effects of lactation on self-fed supplement intake; and 3) influence of cow age on hand-fed supplement intake. For the first study, treatments consisted of non grazed, 2X and 3X grazed. Crude protein of forage grazed 3X...

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...

Evaluation of perennial ryegrass straw as a forage source for ruminants

Creator:: Fisher, Michael J.
Abstract:: We conducted two experiments evaluating perennial ryegrass straw as a forage source for ruminants. Experiment 1 evaluated digestion and physiological variables in steers offered perennial ryegrass straw containing increasing levels of lolitrem B. Sixteen ruminally cannulated Angus X Hereford steers (231 ± 2 kg BW) were blocked by weight and...

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...
