Survival Of Canine Epididymal Sperm Under Cooled And Frozen-Thawed Conditions, Karla Stilley Jan 2001

Survival Of Canine Epididymal Sperm Under Cooled And Frozen-Thawed Conditions, Karla Stilley

LSU Master's Theses

The objective of the first experiment was to determine the effects of storage at 22„aC vs. 4„aC on the motility and percentage of membrane-intact sperm (%MIS) of epididymal mouse sperm. Testicles were allocated into 22„aC or 4„aC treatment groups and stored for 24 or 48 hours. Additional testicles were allocated into the 4„aC treatment for storage for 72 or 96 hours. Sperm was collected and analyzed at each time point. Storage at 22„aC lowered motility and %MIS (P<0.05) when compared with control sperm and 4„aC sperm at both the 24 and 48 hours. Motility and %MIS of 4„aC sperm did not decrease when compared with the control until after 72 hours of storage. The second experiment evaluated the effects of 22„aC vs. 4„aC storage for 24 and 48 hours on epididymal dog sperm. Motility and %MIS of the 22„aC sperm was lower than that of the 4„aC sperm and the control (P<0.05) at 24 and 48 hours. Motility of the 4„aC sperm was lower than the control at 24 and 48 hours (P<0.05), however %MIS was not lower than the control until 48 hours. The third experiment tested the effect of cryopreservation on epididymal dog sperm. Sperm was frozen immediately (A), after 48 hours at 4„aC in liquid (B) or after 48 hours at 4„aC of the whole testicle (C). Both pre-freeze (PF) and post-thaw (PT) motility and %MIS of B and C were lower than A (P<0.05). PT values were lower than PF values in all treatments (P<0.05). PT motility of B was lower than C (0 vs. 35.0¡Ó3.6%). Storage at 4„aC allows collection of motile epididymal mouse and dog sperm for several days after death. Dog testicles can be refrigerated for 2 days and epididymal sperm frozen with PT motility and %MIS of 35 and 62%.

Evaluation Of 1996 Beef Cattle Nrc Model And Development Of Net Energy Modifiers, Hushton Block, Trey Patterson, Terry J. Klopfenstein, John Moore Jan 2001

Evaluation Of 1996 Beef Cattle Nrc Model And Development Of Net Energy Modifiers, Hushton Block, Trey Patterson, Terry J. Klopfenstein, John Moore

Nebraska Beef Cattle Reports

Data from 325 treatment means in 35 previous beef cattle feeding studies were used to evaluate the 1996 NRC model for accuracy of gain predictions and to develop predictions of net energy adjusters for use with the model. The model was found to inaccurately predict gain of cattle fed diets varying in ingredients and energy density. Net energy adjusters were used to achieve accurate prediction of gain for each observation and then equations were developed for predicting the level of net energy adjustment required to improve accuracy of gain prediction.

Effect Of Corn Processing On Degradable Intake Protein Requirement Of Finishing Cattle, Rob Cooper, Terry J. Klopfenstein, Doug Jordan, Todd Milton Jan 2001

Effect Of Corn Processing On Degradable Intake Protein Requirement Of Finishing Cattle, Rob Cooper, Terry J. Klopfenstein, Doug Jordan, Todd Milton

Nebraska Beef Cattle Reports

Three finishing trials were conducted to determine effect of corn processing on degradable intake protein requirement of feedlot cattle. Finishing diets consisted of 82% processed corn which was either dry rolled, high moisture, or steam flaked. Degradable intake protein levels were achieved by adding 0 to 2.0% urea (DM basis) to the control diets. Estimates of degradable intake protein requirement for a dry-rolled corn-based diet were approximately 6.3% of dietary DM. Degradable intake protein requirement for high-moisture corn-based diets was approximately 10% of dietary DM. Degradable intake protein requirement for steam-flaked corn-based diet was between 7 and 9.5% of dietary …

Economic Evaluation Of Corn Processing For Finishing Cattle, Rob Cooper, Todd Milton, Terry J. Klopfenstein, Dick Clark Jan 2001

Economic Evaluation Of Corn Processing For Finishing Cattle, Rob Cooper, Todd Milton, Terry J. Klopfenstein, Dick Clark

Nebraska Beef Cattle Reports

A finishing trial was conducted to determine performance of steers fed dry-rolled, high-moisture and steamflaked corn-based diets. High-moisture corn and steam-flaked corn were determined to have 100% and 108% the value of dry-rolled corn, respectively. Estimated costs of corn processing ($/ton) ranged from $1.44 to $1.60 for dry-rolled corn, $1.98 to $2.34 for high-moisture corn, and $6.79 to $7.16 for steam-flaked corn. Economics of high-moisture corn are dependent on the discount at which it is purchased to dry corn. Economics of steam-flaked corn are dependent on corn price, but appear attractive at prices common in Nebraska.

Managing Heat Stress In Feedlot Cattle Using Sprinklers, Shane Davis, Terry L. Mader, Wanda Cerkoney Jan 2001

Managing Heat Stress In Feedlot Cattle Using Sprinklers, Shane Davis, Terry L. Mader, Wanda Cerkoney

Nebraska Beef Cattle Reports

Ninety-six Bos taurus steers were used to determine the effect of water application to feedlot mounds on performance, behavior and tympanic temperature of steers and microclimatic conditions of the mounds. Steers were assigned to 12 pens subjected to no water application (CON), water applied between 1000 and 1200 (AM), or 1400 and 1600 hr (PM). Water application lowered soil temperatures of the mounds with little effect on temperature-humidity index. Tympanic temperatures were lowered by treatment. Performance variables were not affected; however, AM steers were more efficient than PM steers.

The Role Of Muscle Glycogen In Dark Cutting Beef., Dana J. Hanson, Kevin Kirchofer, Chris R. Calkins Jan 2001

The Role Of Muscle Glycogen In Dark Cutting Beef., Dana J. Hanson, Kevin Kirchofer, Chris R. Calkins

Nebraska Beef Cattle Reports

Dark cutting beef occurs when muscle glycogen levels are depleted prior to slaughter. Without glycogen, lactic acid is not produced in postmortem muscle, causing a higher than normal muscle pH. This research was conducted to identify the threshold level of glycogen where the dark cutting condition is likely to occur. These data from muscles varying widely in pH suggest that muscle glycogen levels need to be at or above 80 mmol/kg to prevent the dark cutting beef condition.

Protein Supplements And Performance Of Cows And Calves In June-Calving Production Systems, Amelia Hopkin, Don C. Adams, Terry J. Klopfenstein, Todd Milton, Dick Clark Jan 2001

Protein Supplements And Performance Of Cows And Calves In June-Calving Production Systems, Amelia Hopkin, Don C. Adams, Terry J. Klopfenstein, Todd Milton, Dick Clark

Nebraska Beef Cattle Reports

Lactating, June-calving cows that received protein supplement January through March maintained a lower body condition than dry June cows. Dry, nonsupplemented cows lost more body condition compared to dry, supplemented cows over that same time period. June-born steers wintered at a low rate of gain (.4 lb/day) had higher daily gains on sub-irrigated meadow during May than June born steers wintered at a higher rate of gain (1.6 lb/day). Supplemental protein fed during summer grazing on range increased daily gains for steers wintered at both high and low gains compared to non-supplemented steers.

Wet Corn Gluten Feed Supplementation Of Calves Grazing Corn Residue, D. J. Jordon, Terry J. Klopfenstein, Todd Milton Jan 2001

Wet Corn Gluten Feed Supplementation Of Calves Grazing Corn Residue, D. J. Jordon, Terry J. Klopfenstein, Todd Milton

Nebraska Beef Cattle Reports

Incremental levels of wet corn gluten feed were fed to calves grazing corn residues. Based on statistical and economical analysis of the data collected, feeding wet corn gluten feed (5.0-6.5 lb/ head/day; DM basis) will increase stocking rate on corn residue and reduce winter costs by 11%. Given that 3.5 lb DM/day wet corn gluten feed will meet the protein and phosphorus needs of calves, and feeding above 6.0 lb/d will not increase gains, wet corn gluten feed should be fed at 3.5-6.0 lb DM/day, producing gains from 1.28- 1.88 lb/day.

Restricted Feeding Strategies For Reducing Heat Load Of Yearling Steers, Terry L. Mader, Simone Holt, Tony Scott, Shane Davis

Nebraska Beef Cattle Reports

Eighty-four Bos taurus crossbred steers were used to investigate effects of level and duration of limit feeding feedlot cattle in a hot environment. Restricting feed intake to 70 to 80% of ad libitum for 21 days duration (RES21) or for 42 days duration (RES42) reduced tympanic temperature in both RES21 and RES42 when compared with ad libitum treatment groups under both thermoneutral and hot conditions. Temperature reduction approached 1.5 F0 depending on time of day. Limit feeding feedlot cattle during early summer is a successful tool for enhancing animal comfort by alleviating the combined effects of high temperatures and …

Urinary Allantoin Excretion As A Marker Of Microbial Crude Protein Supply For Cattle, Ryan Mass, D. J. Jordon, Tony Scott, Todd Milton, Terry J. Klopfenstein, David Harmon Jan 2001

Urinary Allantoin Excretion As A Marker Of Microbial Crude Protein Supply For Cattle, Ryan Mass, D. J. Jordon, Tony Scott, Todd Milton, Terry J. Klopfenstein, David Harmon

Nebraska Beef Cattle Reports

Two metabolism trials evaluated urinary allantoin excretion as a noninvasive marker of microbial crude protein flow from the rumen. In the first trial, both urinary allantoin excretion and duodenal purine flow increased as alfalfa intake increased. A positive linear relationship (r2 = .74) existed between the markers. In the second trial, an increase in the metabolizable energy supplied to the animal did not increase urinary allantoin excretion. We concluded that urinary allantoin excretion was an effective, noninvasive marker of microbial crude protein supply.

Urinary Allantoin Excretion Of Finishing Steers: Effects Of Grain Adaptation And Wet Milling Byproduct Feeding, Ryan Mass, D. J. Jordon, Todd Milton, Terry J. Klopfenstein, Rick Stock

Nebraska Beef Cattle Reports

A metabolism trial investigated microbial protein supply for finishing cattle. In Phase I, cattle were adapted to a dry-rolled corn diet. Urinary allantoin excretion was positively correlated with TDN supply. In Phase II, cattle were fed that diet or diets with a portion of the corn replaced by one of two levels of the corn wet milling byproducts steep liquor or distillers’ solubles. Byproducts inclusion did not increase microbial crude protein supply, as measured by urinary allantoin excretion. Rumen pH also correlated with microbial crude protein supply.

Economic Returns Of Wet Byproducts As Cattle Feed, Richard K. Perrin, Terry J. Klopfenstein Jan 2001

Economic Returns Of Wet Byproducts As Cattle Feed, Richard K. Perrin, Terry J. Klopfenstein

Nebraska Beef Cattle Reports

Research at the University of Nebraska and other institutions has demonstrated the feasibility of feeding corn sweetener/ethanol industry byproducts directly to cattle in wet form, rather than marketing them as dried feeds. Using a combination of experimental results, survey data and market prices, the average value of these wet feed products was about $130 per ton of dry matter during the 1990s, compared to their alternative value as dried feed of $93 per ton. Given the amounts fed, the annual net benefits of this innovation in Nebraska grew from about $1 million in 1992 to an annual average of about …

Corn Processing Method In Finishing Diets Containing Wet Corn Gluten Feed, Tony Scott, Todd Milton, Terry J. Klopfenstein, Rick Stock Jan 2001

Corn Processing Method In Finishing Diets Containing Wet Corn Gluten Feed, Tony Scott, Todd Milton, Terry J. Klopfenstein, Rick Stock

Nebraska Beef Cattle Reports

Two trials were conducted to determine the effects on performance and carcass characteristics of corn grain diets differing in degree of processing and containing wet corn gluten feed. Generally, more intensive processing methods such as fine-grinding, high moisture ensiling, and steam-flaking resulted in lower daily feed consumption compared to feeding rolled or whole corn. Feed efficiency and dietary net energy concentration tended to be improved by more intensive processing methods in finishing diets containing wet corn gluten feed.

Programmed Gain Finishing Systems In Yearling Steers Fed Dry-Rolled Corn Or Wet Corn Gluten Feed Finishing Diets, Tony Scott, Todd Milton, Terry J. Klopfenstein Jan 2001

Programmed Gain Finishing Systems In Yearling Steers Fed Dry-Rolled Corn Or Wet Corn Gluten Feed Finishing Diets, Tony Scott, Todd Milton, Terry J. Klopfenstein

Nebraska Beef Cattle Reports

One hundred sixty crossbred yearling steers were used in a completely randomized design to determine the response to a programmed gain finishing system in diets with and without wet corn gluten feed. Including a programmed gain phase in the finishing period reduced daily gain, hot carcass weight, fat thickness and marbling score in diets with and without wet corn gluten feed. Diets containing wet corn gluten feed increased daily gain, hot carcass weight and fat thickness compared with diets containing only dry-rolled corn. Programming gain improved efficiency but reduced net return per animal and increased cost of gain versus ad …

Annual Forage Production And Quality Trials, Burt Weichenthal, David Baltensperger, Kenneth P. Vogel Jan 2001

Annual Forage Production And Quality Trials, Burt Weichenthal, David Baltensperger, Kenneth P. Vogel

Nebraska Beef Cattle Reports

Two-year forage trials showed higher dry matter yields for winter triticale than for winter wheat while forage qualities were similar. Likewise, a spring triticale cultivar had higher dry matter yields than spring barley or oat cultivars when harvested for forage after heading, and forage qualities were similar. In summer trials, dryland forage sorghum and sorghum x sudangrass hybrids had higher crude protein, digestibility and energy values than irrigated forages because they were not as mature. Lower lignin content and higher digestibility resulted when the brown midrib trait was present in forage sorghum or sorghum x sudangrass hybrids.

Early History Of The Wolf, Black Bear, And Mountain Lion In Arkansas, Annalea K. Bowers, Leah D. Lucio, David W. Clark, Susan P. Rakow, Gary A. Heidt Jan 2001

Early History Of The Wolf, Black Bear, And Mountain Lion In Arkansas, Annalea K. Bowers, Leah D. Lucio, David W. Clark, Susan P. Rakow, Gary A. Heidt

Journal of the Arkansas Academy of Science

During the nineteenth century settlement of Arkansas, the red wolf (Canis rufos), black bear (Ursus americanus), and mourtain lion (Puma concolor) were not only the three largest and most dangerous predators, they also stirred the imaginations of explorers and settlers. References to these species appeared prominently in the journals of early explorers such as George W. Featherstonhaugh (1844) and Frederick Gerstaecker (1854), and their presence inspired voluminous collections of stories and tall tales. Black bears were so common that a large trade developed in pelts, oil, and other body parts, and Arkansas became commonly known as "The Bear State." Wolves …

Perceived Damage By Elk In The Arkansas Ozarks, Jennifer H. Herner-Thogmartin, Kimberly G. Smith, Michael E. Cartwright

Journal of the Arkansas Academy of Science

Wildlife managers in Arkansas are faced with managing a growing population of Rocky Mountain elk (Cervus elaphus neloni) that has extended its range to incorporate private lands near the Buffalo National River (BNR) in northcentral Arkansas. This range expansion has created conflicts between private landowners and wildlife management personnel. To document the extent of damage and assess attitudes of landowners with elk on their land, interviews were conducted with landowners who contacted us or the Arkansas Game and Fish Commission about problems with elk. A survey also was created and sent to landowners who live near the BNR in Boone …

Breeding Season Distribution Of Cerulean Warblers In Arkansas In The 1990s, Douglas A. James, Christopher J. Kellner, Jan Self, Jerry Davis Jan 2001

Breeding Season Distribution Of Cerulean Warblers In Arkansas In The 1990s, Douglas A. James, Christopher J. Kellner, Jan Self, Jerry Davis

Journal of the Arkansas Academy of Science

The Cerulean Warbler (Dendroica cerulea) has been declining in numbers in its North American nesting range, and the same is true in Arkansas. To provide specific sites that can be monitored in the future, this study describes places where the bird was documented in the state in the 1990s. The warbler was found in mature deciduous forest in both upland and bottomland situations but was most abundant in the upland Ozark forests and uncommon in other regions of the state. Most (70%) of the occupied sites were on federal and state lands. Pattern of overall distribution was essentially the same …

Identification Of Florida Largemouth Bass Alleles In Arkansas Public And Private Aquaculture Ponds, Ronald L. Johnson, Randall Staley Jan 2001

Identification Of Florida Largemouth Bass Alleles In Arkansas Public And Private Aquaculture Ponds, Ronald L. Johnson, Randall Staley

Journal of the Arkansas Academy of Science

The Florida subspecies of the largemouth bass (LMB) has often been introduced into waters outside of its range, with escape of individuals into associated waterways common. Sustaining pure lines within controlled hatchery settings is also difficult. The present study investigated LMB populations by way of allozyme analysis of three diagnostic loci of 115 LMB in three public and seven private aquaculture ponds within Arkansas. The goal was to determine the success of hatcheries in maintaining pure subspecies. None of the pond populations studied were fixed for all alleles. Private ponds had northern LMB allele frequencies of up to 0.40 in …

Journal of the Arkansas Academy of Science

During the past 20 years (1982-2001) we have studied the biology, occurrence and distribution of LeConte's (Brazilian) free-tailed bat, Tadarida brasiliensis cynocephala, in Arkansas. Colonies and individuals were reported from man made structures only. Four new county records have been documented since 1988, extending the range from the central part of the state to Arkansas's northern-most tier of counties. Numerous nuisance maternity colonies were investigated during exclusion activities and one, year-round colony provided the majority of reproductive data. A total of 152 free-tailed bats was submitted to the Arkansas Department of Health Rabies Laboratory (1982-2001); most during February through April, …
