Lipid And Ndf Analysis Of Ethanol Byproduct Feedstuffs, Virgil R. Bremer, Crystal D. Buckner, Andrew W. Brown, Timothy P. Carr, Ruth M. Diedrichsen, Galen E. Erickson, Terry J. Klopfenstein
Nebraska Beef Cattle Reports
A newly developed biphasic feed lipid extraction procedure has increased accuracy relative to Goldfisch ether extraction, especially for condensed corn distillers solubles samples. A pre-NDF fat extraction must be completed prior to analyzing high fat feeds for NDF. Corn should be ground through a 1-mm screen on a Tecator Cyclotec sample mill to accurately determine corn NDF content.

Metabolism Characteristics Of Feedlot Diets Containing Different Fat Sources, Virgil R. Bremer, Kelsey Rolfe, Crystal D. Buckner, Galen E. Erickson, Terry J. Klopfenstein
Nebraska Beef Cattle Reports
A metabolism trial was conducted to evaluate the effects of dietary fat source on the metabolism characteristics of feedlot steers fed 8.5% fat (7% fatty acids) diets. Steers fed condensed corn distillers solubles (CCDS) had lower average pH and greater DM digestibility than those fed corn oil, tallow, or WDGS. Steers fed CCDS also had greater fat and fatty acid digestibility than corn and corn oil fed steers and greater NDF digestibility than corn oil or tallow fed steers. Although CCDS fat is similar to corn oil, the two feeds are digested differently. The omasal fatty acid profile of steers …

Factors Associated With Feed Intake Of Angus Steers, Marco G. Dib, Jeremy F. Taylor, Robert D. Schnabel, L. Dale Van Vleck
Nebraska Beef Cattle Reports
Estimates of variance components and heritability of average daily feed intake (AFI) and residual feed intake (RFI) were obtained using an animal model. Data were from 475 Angus steers raised and fed at the Circle A Ranch (Iberia, Mo.). Pedigree files were provided by the American Angus Association. Estimates of heritability after adjustment for average daily gain (ADG) were 0.56 and 0.60 for AFI and RFI. Selection for feed intake (FI) should be effective if FI records are available. Feed intake needs to be adjusted for age and weight on test. Carcass measurements (fat thickness and rib eye muscle area) …
Effect Of Calving Season And Wintering System On Cow Performance, William A. Griffin, Don C. Adams, Leslie Aaron Stalker, Richard N. Funston, Jacqueline A. Musgrave, Terry J. Klopfenstein, Galen E. Erickson
Effect Of Calving Season And Wintering System On Cow Performance, William A. Griffin, Don C. Adams, Leslie Aaron Stalker, Richard N. Funston, Jacqueline A. Musgrave, Terry J. Klopfenstein, Galen E. Erickson
Nebraska Beef Cattle Reports
Four years of data from three different calving seasons and two different cow wintering systems were evaluated utilizing 218 cows/year. Cows calved in spring, summer, or fall and were wintered on native Sandhills range or cornstalks. Calving season affected cow body weight (BW) and body condition score (BCS) throughout the production year; calving in the fall reduced number of calves weaned per cow. No differences were observed between cows wintered on Sandhills range and those wintered on cornstalks.

Acid Marination For Tenderness Enhancement Of The Beef Bottom Round, Jeremy H. Hinkle, Chris R. Calkins, Amilton S. De Mello Jr., Lasika S. Senaratne, Siroj Pokharel
Nebraska Beef Cattle Reports
Two experiments were conducted to evaluate acid marination to enhance tenderness of the beef bottom round (m. biceps femoris). Both experiments consisted of 3 acid types (acetic, lactic, and citric) and two concentrations (0.1 and 0.5 M in Exp. 1; 0.75 and 1.5 M in Exp. 2). There were no effects of acid marination on beef tenderness in Exp. 1, although lightness (L*) increased and redness decreased from 0 to 8 hours post-marination. Acetic and lactic acid (0.75 or 1.5 M) improved shear force values above those achieved by citric acid. Both lightness and redness permanently decreased in Exp. 2. …
Tympanic Temperature Profiles Of Confined Beef Cattle, Terry L. Mader, Leslie J. Johnson
Tympanic Temperature Profiles Of Confined Beef Cattle, Terry L. Mader, Leslie J. Johnson
Nebraska Beef Cattle Reports
Angus crossbred yearling steers were used to evaluate tympanic temperature (TT) profile of cattle displaying high, moderate, or low levels of heat stress. Data indicate cattle that do not adequately cool down at night are prone to greater body temperatures during a subsequent hot day. Cattle that are prone to displaying moderate levels of heat stress but can cool at night will maintain average tympanic temperatures at or near those of cattle that tend to consistently maintain lower peak tympanic temperatures. In addition, during cooler and moderately hot periods, cattle change TT in a stair-step or incremental pattern, while under …

Supplementing Wet Distillers Grains Mixed With Low Quality Forage To Grazing Cow/Calf Pairs, Brandon L. Nuttelman, William A. Griffin, Terry J. Klopfenstein, Walter H. Schacht, Leslie Aaron Stalker, Jacqueline A. Musgrave, Jerry D. Volesky
Nebraska Beef Cattle Reports
Two studies were conducted over two years during the summer grazing season to determine the effect of grass intake when grazing cow/calf pairs were supplemented wet distillers grains (WDGS) with low quality forage. In 2007, a mixture of 45% WDGS and 55% grass hay was fed. In 2008, three blends of 50:50, 60:40, and 70:30 WDGS and wheat straw were fed. Supplemented cows and calves outgained non-supplemented groups in 2007. There were no differences in animal performance during 2008. Grazed forage intake was reduced by supplementing WDGS mixed with wheat straw without negatively affecting animal performance.

Comparison Of Feeding Wet Distillers Grains In A Bunk Or On The Ground To Cattle Grazing Native Sandhills Winter Range, Jacqueline A. Musgrave, Leslie Aaron Stalker, Matthew C. Stockton, Terry J. Klopfenstein
Nebraska Beef Cattle Reports
Two experiments determined the effects of feeding wet distillers grains with solubles (WDGS), either on the ground or in a bunk, to cattle grazing native Sandhills winter range. In Exp. 1, frequency of supplementation had no effect on cow body weight (BW) or body condition score (BCS). BCS and BW of cows fed in a bunk were improved compared to cows fed on the ground. In Exp. 2, steers fed in a bunk had greater average daily gain than steers fed on the ground. Feeding WDGS on the ground resulted in 13-20% waste and cost between$0.03 and $0.045 per day.
Extending Grazing In Heifer Development Systems Decreases Cost Without Compromising Production, Daniel M. Larson, Andrea S. Cupp, Richard N. Funston
Extending Grazing In Heifer Development Systems Decreases Cost Without Compromising Production, Daniel M. Larson, Andrea S. Cupp, Richard N. Funston
Nebraska Beef Cattle Reports
Three experiments compared heifer development in the dry lot, grazing either dormant winter range or corn crop residue. Grazing corn residue may reduce pre-breeding gain and in doing so increase age at puberty. Compared to dry lot development, grazing corn residue reduced AI pregnancy rate, but final pregnancy rate was similar for both development tsystems. Calf production and rebreeding efficiency were not affected by the development system. However, grazing corn residue during heifer development reduced cost compared to development in the dry lot. Developing heifers by grazing dormant forage does not affect final pregnancy rate and reduces cost, improving the …
Feeding Fiber From Wet Corn Gluten Feed And Corn Silage In Feedlot Diets Containing Wet Distillers Grains Plus Solubles, Amy R. Rich, Matt K. Luebbe, Galen E. Erickson, Terry J. Klopfenstein, Joshua R. Benton
Feeding Fiber From Wet Corn Gluten Feed And Corn Silage In Feedlot Diets Containing Wet Distillers Grains Plus Solubles, Amy R. Rich, Matt K. Luebbe, Galen E. Erickson, Terry J. Klopfenstein, Joshua R. Benton
Nebraska Beef Cattle Reports
A feedlot experiment evaluated the effect of increasing fiber in distillers grains diets on ADG, F:G, and nutrient mass balance. The treatments consisted of 1) 30% modified distillers grains plus solubles, no roughage (MDGS), and 2) 30% modified distillers grains plus solubles, 30% wet corn gluten feed, and 15% corn silage (MDGS+fiber). The remainder of each diet consisted of a 1:1 ratio of high moisture corn and dry rolled corn and 5% supplement. Feeding MDGS+fiber increased (P < 80.02) ADG, DMI, and HCW; however, it did not improve F:G compared to MDGS. By increasing the fiber content of the diet, more organic matter (OM) and N remained in the manure. Percentage N loss was not different between dietary treatments; however, amount of N lost increased with MDGS + fiber due to the greater N intake and excretion.

Effects Of Using Wet Distillers Grains With Solubles To Adapt Cattle To Finishing Diets On Feed Intake, Ruminal Ph, And Ruminal Hydrogen Sulfide Concentration, Kelsey Rolfe, Galen E. Erickson, Terry J. Klopfenstein, Judson Vasconcelos
Nebraska Beef Cattle Reports
An adaptation strategy with wet distillers grains with solubles (WDGS) fed at decreasing levels (87.5 to 35%) was compared to a traditional grain adaptation with decreasing forage (45 to 7.5%) when adapting steers to a common finishing diet. Traditionally adapted steers had higher intake in steps one through three compared to steers adapted with distillers grains. However, DMI was not different between the two adaptation systems in step four, or when steers were on the finishing diet. Ruminal pH was higher for traditionally adapted steers compared to steers adapted to distillers grains in adaptation diets two and three. Ruminal hydrogen …
Routine Hedging Of Fed Cattle Sales Price For Calf-Fed And Yearling Production Systems, Rebecca M. Small, Darrell R. Mark, Terry J. Klopfenstein Klopfenstein
Routine Hedging Of Fed Cattle Sales Price For Calf-Fed And Yearling Production Systems, Rebecca M. Small, Darrell R. Mark, Terry J. Klopfenstein Klopfenstein
Nebraska Beef Cattle Reports
Short futures hedges in the Chicago Mercantile Exchange live cattle futures contract were evaluated to determine if profit variability could be decreased for calf-fed and yearling production systems. Results indicated standard deviations of calf-fed profits could be reduced by $35-$47/head through routine hedging. Routine hedges of yearling cattle, however, resulted in profit declining nearly $50/head, but profit variability also decreased.

Distribution Of The Southeastern Shrew (Sorex Longirostris Longirostris) In Arkansas, G. A. Mikel, Gary A. Heidt, David W. Clark
Journal of the Arkansas Academy of Science
The southeastern shrew (Sorex longirostris longirostris) is considered uncommon and, due to a lack of knowledge, a Species of Greatest Conservation Need in Arkansas. Also, eastern Arkansas may represent a gap in the species’ distribution. Therefore, we evaluated persistence at previous capture sites, surveyed additional counties, quantified microhabitat at our capture locations, and compiled occurrences. Since Sealander and Heidt’s (1990) Arkansas Mammals detailed its occurrence, additional captures by Huston and Nelson (1994), Showen (2006), and this study document new counties (Pope and Searcy) and a new ecoregion (Arkansas Valley). Number of specimens in Arkansas has increased to 17 in 11 …

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research
Studies of the neural mechanisms of learning, especially of sensitization, have benefitted from extensive research on the model species, Aplysia californica (hereafter Aplysia). Considering this volume of literature on mechanisms, it is surprising that our understanding of the ecological context of sensitization in Aplysia is completely lacking. Indeed, the widespread use of strong electric shock to induce sensitization (an enhancement of withdrawal reflexes following noxious stimulation) is completely unnatural and leaves unanswered the question of whether this simple form of learning has any ecological relevance. We hypothesized that sublethal attack by a co-occurring predator, the spiny lobster, Panulirus interruptus, might …

The aim of this study was to determine the effects of parenteral administration of L-carnitine on some biochemical parameters in Halep (Damascus) goats during the last month of pregnancy. L-carnitine was administrated to goats in group I (n = 13) by subcutaneous injections once a week during the last month of the pregnancy. Physiologic salt solution was administered to goats in group II (n = 12) by the same route during the same period. Differences of glucose concentration between groups were not significant (P > 0.05). Serum \beta-hydroxybutyric acid (BHB) concentrations in both groups increased until parturition. However, differences between groups …
