Nebraska Beef Cattle Reports
A 173-day finishing experiment was conducted to evaluate the effects of feeding RAMP (Cargill Corn Milling, Blair, NE) during diet adaptation compared to a traditional forage adaptation program on methane and carbon dioxide emissions, animal performance and carcass traits in beef steers. Cattle were monitored using a calorimetry emission barn to quantify production of methane and carbon dioxide during step 1 of grain adaptation and at two subsequent times while fed a common finishing diet. Feeding RAMP reduced methane by 12% during the initial diet (step 1) compared to a traditional diet that contained 43% forage. When cattle were fed …

Nebraska Beef Cattle Reports
Reproductive performance in young 2- and 3-yr-old cows are often the lowest in the cow herd, which is due to their inability to consume enough energy and protein to meet their requirements for growth and lactation. A 3-yr study was conducted to evaluate the effects of postpartum supplementation strategy on reproduction, cow body weight, and calf performance in lactating young 2- and 3-yr-old May-calving range cows. Supplementation was initiated 20 d prior to the start of the breeding season (45-d postpartum) and continued throughout the 45-d breeding season (125-d postpartum). Supplementation was provided daily with treatments being 1) mineral supplement …

Statistics Used In The Nebraska Beef Reports And Their Purpose, University Of Nebraska-Lincoln
Nebraska Beef Cattle Reports
The purpose of beef cattle and beef product research at UNL is to provide reference information that represents the various populations (cows, calves, heifers, feeders, carcasses, retail products, etc) of beef production. Obviously, the researcher cannot apply treatments to every member of a population; therefore he/she must sample the population. The use of statistics allows the researcher and readers of the Nebraska Beef report the opportunity to evaluate separation of random (chance) occurrences and real biological effects of a treatment. Following is a brief description of the major statistics used in the beef report. For a more detailed description of …

Impact Of Strip-Grazing Stockpiled Annual/Cover Crop Forages On Carrying Capacity And Animal Performance, Shelby L. Davies-Jenkins, Abigail Sartin, Devin Jakub, Zac Carlson, Erin Laborie, Jack Arterburn, Ben Beckman, Brad Schnick, M. E. Drewnoski
Nebraska Beef Cattle Reports
Annual forages/cover crops can be used to fill the fall/winter grazing gap, and strip grazing may increase carrying capacity by reducing trampling losses of the forage. The current experiment utilized a series of on-farm experiments across two growing seasons to compare continuous and strip grazing of various summer planted cover crops. Strip grazing increased carrying capacity by an average of 47 ± 15% and gain per acre by 44 ± 5% compared to continuous grazing although significant variability in the amount of increase was observed. This variability can likely be attributed to forage type (quality), frequency of moves, and forage …

Nebraska Beef Cattle Reports
The young calf is at greatest risk of vitamin A deficiency when cow vitamin intake is low in late pregnancy. Two studies were conducted to evaluate the relationship between cow and calf vitamin A status and how vitamin A status of cow-calf pairs was influence by maternal vitamin A supplementation. In general, calves did not have adequate liver vitamin A concentrations despite cows having adequate liver vitamin A stores following calving. Both cow iver stores and cow vitamin A intake during late gestation influence the amount of vitamin A in colostrum, so it benefits the calf if the cow has …

A retrospective study was done utilizing 1,434 March- and May- calving Red Angus x Simmental crossbred cows and heifers from 2005 through 2019. Heifer weight as a percentage of mature body weight at breeding was used to conduct a regression analysis from 50 to 70% of mature body weight to determine the impact of body weight at breeding on reproductive performance. Heifer pregnancy rates and second pregnancy rates as 2-year-olds were greater for heifers at 60, 65, and 70% of mature body weight at breeding than heifers at 50 and 55%. However, heifer percent mature body weight at breeding did …
Current And New Perspectives On Equine Protozoal Myeloencephalitis Therapeutics, Izabela De Assis Rocha
Current And New Perspectives On Equine Protozoal Myeloencephalitis Therapeutics, Izabela De Assis Rocha
Theses and Dissertations--Veterinary Science
Equine protozoal myeloencephalitis (EPM) is an important neurologic disease of horses in the Americas. It is caused by the apicomplexan parasite Sarcocystis neurona and less commonly by the related parasite Neospora hughesi. Current antiprotozoal treatment relies on the use of either folate inhibitors (sulfadiazine/pyrimethamine) or triazine drugs (diclazuril/ponazuril), with a success rate of 60-70% regardless of the drug of choice. Successful treatment is defined as the improvement of at least one ataxia grade following the modified Mayhew scale, which often is not enough for the horse to return to the previous level of performance. The goals of this dissertation …
Ethyl Pyruvate Failed To Reduce Pro-Inflammatory Cytokines Release Following In Vitro Stimulation In Dairy Calves' Whole Blood., Vincent Dore
Doctoral Dissertations
Recent developments in sepsis treatment showed that control of the late mediator of inflammation, High Mobility Box group-1 (HMGB1), improves survival in animal models of endotoxemia. Ethyl pyruvate is a small-molecule inhibitor that has been shown to reduce the systemic release of HMGB1 during experimental treatment of systemic inflammation in different species. The objectives of this body of work were 1) to explore ethyl pyruvate's ability to modulate early pro-inflammatory cytokines production and immune effector function in treated calves, 2) to evaluate the safety of an administration of ethyl pyruvate infusion in neonatal calves, and 3) to explore ethyl pyruvate's …

Delayed Urethral Obstruction After Migration Of A Ballistic Pellet In An Alpine Wether, Joseph Smith
Faculty Publications and Other Works -- Large Animal Clinical Sciences
A one-year-old alpine wether was presented for emergency evaluation of stranguria. Diagnostics identified a moderately distended bladder and mild dehydration. Preliminary lateral radiographs identified two metallic structures consistent with projectile pellets in the pelvic and perineal regions and no evidence of radiopaque uroliths. A tube cystostomy was performed, and a contrast urethrogram revealed one of the pellets in the perineal region was in proximity to the urethral obstruction. Subsequent radiography and ultrasound identified the pellet as being within the lumen of the urethra. Examination of the trichotomized skin revealed two scars, including a scar over the paralumbar fossa in the …

Identifying Barriers To Data Use On U.S. Beef Cow-Calf Operations And Developing Solutions To Improve Cow-Calf Record-Keeping, William Isaac Jumper
Theses and Dissertations
Cattle health and production records (CHPR) are data collected by cattle producers and veterinarians in the form of measurements, observations, counts of events over time, and physiologic attributes that describe individual and group-level health and production. These data are useful to both veterinarians and cattle producers for making evidence-based decisions on cow-calf operations. Currently, there are no uniform, industry-wide methods of capturing and recording CHPR in the U.S. cow-calf industry. Although many cow-calf producers in the U.S. are thought to collect some form of CHPR, it is believed that relatively few are doing so in an electronic manner that facilitates …

The Effects Of Artificial Insemination On Beef Cattle In The United States, Allee R. Sweeten, Abigail Shelnut, Madison Dickey
ATU Research Symposium
Artificial insemination (AI) is a reproductive procedure widely used in cattle industries and other livestock to increase pregnancy rates. Breeders must wait until the animals are in the estrus part of their estrous cycle to AI. Estrus synchronization is utilized to manipulate the estrous cycle to go into estrus or standing heat. AI is conducted by loading a semen straw into an inseminating gun, inserting the gun into the vagina of the heifer, and making sure it gets past the cervix by palpating with the other hand. Once past the cervix, the semen can be distributed in the heifer. AI …
Pharmacokinetics Of Single Feeding Of Cannabidiol In Cattle: A Pilot Study, Haley Cornette
Pharmacokinetics Of Single Feeding Of Cannabidiol In Cattle: A Pilot Study, Haley Cornette
Honors College Theses
Cannabidiol (CBD) is a substance that has been used in complementary medicine for many years. However, modern medicine has little knowledge of how this substance is utilized and metabolized in ruminant animals. Regulations on quality assurance and use in animals are lacking, and CBD supplementation in livestock is not approved. If CBD supplements can be shown to be safe and effective, detection in the animal will be important for determining regulation of use. A withdrawal period can then be established to allow time for deterioration of product to safe levels before livestock products enter human markets. This study sought to …

Pigs are at risk of vomiting from medical conditions as well as the emetic side effects of drugs administered for peri-operative manipulations, but there is a lack of pharmacokinetic data for potential anti-emetic therapies, such as maropitant, in this species. The main objective of this study was to estimate plasma pharmacokinetic parameters for maropitant in pigs after a single intramuscular (IM) administration dosed at 1.0 mg/ kg. A secondary objective was to estimate pilot pharmacokinetic parameters in pigs after oral (PO) administration at 2.0 mg/kg. Maropitant was administered to six commercial pigs at a dose of 1.0 mg/kg IM. Plasma …
Whole Genome Sequencing For Identification Of Putative Causative Alleles For Hemochromatosis In Horses, Anna M. Rauber-Ramos
Whole Genome Sequencing For Identification Of Putative Causative Alleles For Hemochromatosis In Horses, Anna M. Rauber-Ramos
Schultz-Werth Award Papers
Hemochromatosis is liver disorder in which excess iron is stored in the liver, leading to iron overload and extensive liver damage that can prove fatal. Based on human precedence, a genetic cause for idiopathic hemochromatosis in horses is suspected. Two horses with hemochromatosis were whole genome sequenced, with variants in candidate genes prioritized in analyses of potential pathogenicity. No clear putative variants were found to be present in both horses, suggesting an etiology more complex than the initially suspected Mendelian inheritance. A heterozygous nonsense mutation in STEAP3 metalloreductase (STEAP3) was identified as a potential contributor to hemochromatosis in one of …

Effects Of High-Speed Training On Messenger Rna Expression In Two-Year-Old Thoroughbred Racehorses, Mackenzie Grace Johnson
Theses and Dissertations--Veterinary Science
Accumulating high-speed exercise has been identified as a significant risk factor for catastrophic injuries in racing Thoroughbreds. Injuries, regardless of severity, are a main cause of withdrawal from the racing industry, raising animal welfare concerns and resulting in significant economic losses. While most of the current literature focuses on catastrophic injuries incurred during racing rather than training, the present study aims to help fill this gap as well as discuss the associated risk factors. The evaluation of messenger RNA (mRNA) expression changes provides an efficient and straightforward approach to identifying horses at risk for catastrophic injury. While alternative injury risk …
