Artificial Insemination And Fetal Programming In Beef Production Systems, Dempster Christenson
Artificial Insemination And Fetal Programming In Beef Production Systems, Dempster Christenson
Department of Animal Science: Dissertations, Theses, and Student Research
Pregnancy to artificial insemination and late gestation fetal programming of the next calf crop are central to genetic development, reproductive longevity, calf crop productivity, and efficiency of cow/calf ranching. The purposes of this research are to find methods to improve pregnancy rate to artificial insemination, the growth and reproductive health of pregnant heifers, and the productivity of their offspring. In the first of four studies we found that extending the period of progesterone administration in an estrus synchronization protocol did not significantly hasten estrus response or increase pregnancy rate to artificial insemination, but timing of estrus within the melengestrol acetate …

In addition to their value as cereal grains, wheat (Triticum aestivum L.) and triticale (× Triticosecale Wittmack) are important cool-season annual forages and cover crops. Yearling steer (Bos taurus) performance was compared in the spring following autumn establishment as for age cover crops after soybean [Glycine max (L.) Merr.] grain harvest. Replicated pastures (0.4 ha) were no-till seeded in three consecutive years into soybean stubble in autumn, fertilized, and grazed the following spring near Ithaca, Nebraska, USA. Each pasture (n = 3) was continuously stocked in spring with four yearling steers (380 ± 38 kg) for …
Investigation Of Breeding Objectives And Indexes-In-Retrospect, Hunter F. Valasek
Investigation Of Breeding Objectives And Indexes-In-Retrospect, Hunter F. Valasek
Department of Animal Science: Dissertations, Theses, and Student Research
This thesis presents two projects that investigate the impacts of breeding objectives and indexes-in-retrospect within the beef cattle industry. The first project synthesized how changes due to planning horizon, breeding system, and sale endpoint in the economic breeding goal of cattle influence the relative emphasis of traits as well as the re-ranking of selection candidates. A total of three breeding systems that represent straightbred and crossbred cattle were used along with six planning horizons (2, 5, 10, 20, 30, and 50 yrs.) for both a weaning and slaughter point of sale. The combination of these different breeding objective attributes resulted …

Use Of Livestock Risk Protection Insurance For Cattle Continues To Grow, Jay Parsons
Use Of Livestock Risk Protection Insurance For Cattle Continues To Grow, Jay Parsons
Cornhusker Economics
When used as a regular part of a market risk management plan, livestock risk protection (LRP) insurance can help protect profits in years where markets turn for the worse. The recent changes to the program have made LRP insurance more appealing to cattle producers and sales of LRP have subsequently increased dramatically. Strong price increases may make LRP unnecessary, but it is difficult to predict when the price increases will end. LRP insurance is a safety net, reducing downside price risk by providing a floor on national price expectations while also allowing producers to take advantage of higher national prices …
Regional Minimums In The U.S. Beef Complex, Elliott James Dennis, Bradley Lubben
Regional Minimums In The U.S. Beef Complex, Elliott James Dennis, Bradley Lubben
Center for Agricultural Profitability
This report shows how the currently proposed policies differ; shows how these policies have aligned with historical market behavior; provides alternative specifications to regional minimums; and suggests policy alternatives to regional minimums.
The main purpose of this report is to show how current and potential alternative specifications of regional minimums would have historically aligned with observed market behavior. However, the fundamental question in the debate of the validity and effectiveness of regional minimums first rests on whether robust price discovery has historically occurred over time and within each USDA-AMS region. If there has been a lack of price discovery during …
Drought Mitigation For Cow/Calf Producers: Depopulation Strategies, Reganne K. Briggs, Joshua Dallin, Jacob Hadfield, Matthew D. Garcia
Drought Mitigation For Cow/Calf Producers: Depopulation Strategies, Reganne K. Briggs, Joshua Dallin, Jacob Hadfield, Matthew D. Garcia
All Current Publications
Drought is a recurring event faced by many cow/calf producers across the nation. As drought events increase in their severity, it is important for cattle producers to have a management plan to mitigate the economic effects of drought. Two of the most common strategies for mitigating the effects of drought include buying additional feed and depopulating a portion of the herd. This fact sheet reviews strategies that will guide the decision-making process to cull cattle during drought.
Predicting Spatial-Temporal Patterns Of Diet Quality And Large Herbivore Performance Using Satellite Time Series, Sean P. Kearney, Lauren M. Porensky, David J. Augustine, Justin D. Derner, Feng Gao
Predicting Spatial-Temporal Patterns Of Diet Quality And Large Herbivore Performance Using Satellite Time Series, Sean P. Kearney, Lauren M. Porensky, David J. Augustine, Justin D. Derner, Feng Gao
United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications
Adaptive management of large herbivores requires an understanding of how spatial-temporal fluctuations in forage biomass and quality influence animal performance. Advances in remote sensing have yielded information about the spatial-temporal dynamics of forage biomass, which in turn have informed rangeland management decisions such as stocking rate and paddock selection for free-ranging cattle. However, less is known about the spatial-temporal patterns of diet quality and their influence on large herbivore performance. This is due to infrequent concurrent ground observations of forage conditions with performance (e.g., mass gain), and previously limited satellite data at fine spatial and temporal scales. We combined multi-temporal …

Feeder Cattle Future Price Spreads: Opportunities To Hedge?, Elliott James Dennis
Feeder Cattle Future Price Spreads: Opportunities To Hedge?, Elliott James Dennis
Extension Farm and Ranch Management News
First paragraph:
Feeder cattle future price spreads across all months have recovered to near pre-COVID-19 levels as quarantine restrictions and packing plant capacity issues have been mostly sorted out. For example, for the week of July 17, 2010 [sic], prices reached levels not seen since the beginning of March 2020. Pasture and corn progress are two factors that have the potential to push prices lower in the next coming months. Given current market conditions, producers have some options to lock in a margin.

Effects Of Supplemental Whole Cottonseed On Weaned Calf Production, Zachary Debord
Effects Of Supplemental Whole Cottonseed On Weaned Calf Production, Zachary Debord
Mahurin Honors College Capstone Experience/Thesis Projects
This study compared the effect of supplemental whole cottonseed in a weaned calf ration on cattle productivity. Feed is the main cost for livestock production. Whole cottonseed supplementation may increase production and reduce the cost of gain for the ration. During the study, 18 beef calves were weaned and split into two groups and fed, with and without WCS, for 50 days to determine the effect of supplemental whole cottonseed. Productivity was determined by measuring average daily gains for each group and comparing cost of gain for each ration. It was determined that WCS did increase productivity of weaned calves …

West Central Research and Extension Center, North Platte
Optimizing beef production system efficiency requires an understanding of genetic potential suitable for a given production environment. Therefore, the objective of this retrospective analysis was to determine the influence of cow body weight (BW) adjusted to a common body condition score (BCS) of 5 at weaning-influenced cow-calf performance and postweaning steer and heifer progeny performance. Data were collected at the Gudmundsen Sandhills Laboratory, Whitman, NE, on crossbred, mature cows (n = 1,607) from 2005 to 2017. Cow BCS at calving, prebreeding, and weaning were positively associated (P < 0.01) with greater cow BW. Increasing cow BW was positively associated (P < 0.01) with the percentage of cows that conceived during a 45-d breeding season. For every additional 100-kg increase in cow BW, calf BW increased (P < 0.01) at birth by 2.70 kg and adjusted 205-d weaning BW by 14.76 kg. Calf preweaning average daily gain (ADG) increased (P < 0.01) 0.06 kg/d for every additional 100-kg increase in cow BW. Heifer progeny BW increased (P < 0.01) postweaning with every additional 100-kg increase in dam BW. Dam BW did not influence (P ≥ 0.11) heifer puberty status prior to breeding, overall pregnancy rates, or the percentage of heifers calving in the first 21 d of the calving season. Steer initial feedlot BW increased by 7.20 kg, reimplant BW increased by 10.47 kg, and final BW increased by 10.29 kg (P ≤ 0.01) for every additional 100-kg increase in dam BW. However, steer feedlot ADG was not influenced (P > 0.67) by dam BW. Hot carcass weights of steers were increased (P = …
Use Of Uav Imagery And Nutrient Analyses For Estimation Of The Spatial And Temporal Contributions Of Cattle Dung To Nutrient Cycling In Grazed Ecosystems, Amanda Shine
Department of Agronomy and Horticulture: Dissertations, Theses, and Student Research
Nutrient inputs from cattle dung are crucial drivers of nutrient cycling processes in grazed ecosystems. These inputs are important both spatially and temporally and are affected by variables such as grazing strategy, water location, and the nutritional profile of forage being grazed. Past research has attempted to map dung deposition patterns in order to more accurately estimate nutrient input, but the large spatial extent of a typical pasture and the tedious nature of identifying and mapping individual dung pats has prohibited the development of a time- and cost-effective methodology. The first objective of this research was to develop and validate …

Feed Efficiency And Carcass Metrics In Growing Cattle, David N. Kelly, Craig Murphy, Roy D. Sleator, Michelle M. Judge, Stephen B. Conroy, Donagh P. Berry
Department of Biological Sciences Publications
Some definitions of feed efficiency such as residual energy intake (REI) and residual gain (RG) may not truly reflect production efficiency. The energy sinks used in the derivation of the traits include metabolic live-weight; producers finishing cattle for slaughter are, however, paid on the basis of carcass weight, as opposed to live-weight. The objective of the present study was to explore alternative definitions of REI and RG which are more reflective of production efficiency, and quantify their relationship with performance, ultrasound, and carcass traits across multiple breeds and sexes of cattle. Feed intake and live-weight records were available on 5,172 …

Beef Production Systems In The Nebraska Sandhills, Mckay Erickson
Department of Animal Science: Dissertations, Theses, and Student Research
Four studies were conducted to determine the effectiveness of improving production systems of beef cattle in the Sandhills region of Nebraska. These studies were to determine impacts of modified estrus synchronization protocols, genomic testing heifer calves for longevity, and evaluation of 2 differing calving systems (March or May) for improving biological outcome and improved production. Experiment 1 utilized 180 yearling heifers to determine the effectiveness of a second dose of prostaglandin F2α(PGF) with those females not expressing estrus after an initial 14 d MGA-PG estrus synchronization protocol. The treatment of PGF did increase estrus expression, but did not …
Selective Harvest Methods And Chemical Treatment Of Baled Corn Residue For Utilization In Growing Calf And Dry Cow Diets, Ashley C. Conway
Selective Harvest Methods And Chemical Treatment Of Baled Corn Residue For Utilization In Growing Calf And Dry Cow Diets, Ashley C. Conway
Department of Animal Science: Dissertations, Theses, and Student Research
Three studies were conducted to evaluate baled corn residue using selective harvest method and anhydrous ammonia treatments to assess utility in growing calf and dry cow diets. Baled corn residue was harvested using conventional rake-and-bale (CONV) method, or harvested using the New Holland Cornrower in which either eight rows (8ROW), or two rows (2ROW) of corn stalks were chopped into the windrow with tailings. Bales were either not treated or ammoniated at 5.5% DM. When fed to wether lambs in a mixed ration (65% residue, 30% wet corn gluten feed) to determine digestibility, the 2ROW residue had greater apparent DM, …

Impact Of Shade On Performance And Heat Stress Of Finishing Cattle And Pooled Analysis Of Individually Fed Finishing Trials, Brett A. Melton
Department of Animal Science: Dissertations, Theses, and Student Research
A commercial feedyard trial in Eastern Nebraska evaluated the effect of shade vs no shade on cattle performance, ear temperature, and panting scores. No differences in overall performance (final BW, DMI, ADG, and G:F) or carcass characteristics (HCW, 12th rib fat thickness, marbling, LM area, and calculated YG) were observed. Cattle that were provided shade had lower panting scores and ear temperatures, and greater DMI, compared to cattle that had no shade during heat events. Also, a treatment by hour interaction for movement of cattle occurred for one of the heat events. In comparison, the cool event had greater …

Identifying Breed Effects For Cow Mature Weight, Madeline J. Zimmermann
Department of Animal Science: Dissertations, Theses, and Student Research
Mature weight (MWT) in beef cattle has increased over the past 30 yr. In general, larger cows are costlier to maintain than smaller cows, and their profitability depends on their production environment. A wide range of beef production environments exist in the United States. There are also a variety of beef cattle breeds that can be chosen and mated to create a type of cow which will be optimally suited to excel in a given environment. However, there remains a need for tools allowing effective comparison among breeds to facilitate such decision making. Unfortunately, estimated progeny differences ( …
