Pooled Analysis Of Individually Fed Finishing Trials, Brett A. Melton, James C. Macdonald, Andrea K. Watson Watson, Galen E. Erickson

Nebraska Beef Cattle Reports

A pooled analysis of 21 finishing trials (2002–2016; 1530 animals) with cattle individually fed in Calan gate barns was conducted. Mixed model regression analysis following random coefficient methodology was used to evaluate relationships between performance variables and carcass characteristics. Gain had a greater effect on efficiency (R² = 0.72) compared to intake (R² = 0.02). The relationship between gain and efficiency was cubic, while intake had a quadratic relationship. The cubic response of gain relative to efficiency was continually increasing with relatively slight curves in the line heavily influenced by points that lay on the ends of the …

Effect Of Adding Urea To Finishing Diets Containing Two Different Inclusions Of Distillers Grains On Steer Performance And Carcass Characteristics, Bradley M. Boyd, James C. Macdonald, Matthew K. Luebbe, Galen E. Erickson

Nebraska Beef Cattle Reports

The effects of adding urea to a dry rolled corn based finishing diet containing low inclusions of distillers grains was evaluated. Treatments were designed as a 2 × 4 factorial arrangement with factors consisting of wet distillers inclusion (either 12 or 20% of diet DM) and urea inclusion (0, 0.4, 0.8, 1.2% of diet DM). There were no significant interactions observed between distillers inclusion and urea inclusion in the diet. Increasing inclusion of distillers grains improved carcass adjusted average daily gain and feed conversion and reduced dry matter intake. Increasing distillers inclusion also increased 12th rib fat and had a …

Impacts Of 40 Years Of The Gudmundsen Sandhills Laboratory On Beef Cattle And Range Systems, Jack C. Whittier, Kelly W. Bruns, Rick N. Funston Funston, Jerry D. Volesky, Terry J. Klopfenstein, Don C. Adams

Nebraska Beef Cattle Reports

The University of Nebraska (UNL) Gudmundsen Sandhills Laboratory (GSL) is a 12,800-acre research ranch in the Nebraska Sandhills. In 1978, Elmer “Pete” and Abbie Gudmundsen gifted the former Rafter C Ranch to the University of Nebraska Foundation. Thus, 2018 was the 40th year of UNL oversight of GSL. To the credit of UNL Administration, GSL development for range livestock research was delegated to a team of Research and Extension Specialists chaired by Dr. Don Clanton.

Parasitism, Host Behavior, And Invasive Species, Sarah N. Bevins

United States Department of Agriculture Wildlife Services: Staff Publications

Animal behavior and parasitism are inextricable linked. In many cases, host behavior can affect what parasites are encountered. In other cases, parasites can manipulate the behavior of the host in an attempt to maximize their own transmission. These long-standing interactions are now further complicated by species movement around the globe. The list of introduced species that have become invasive includes parasites that have adapted to new hosts in areas of introduction, as well as invasive hosts that alter the association between existing parasite–host assemblages. Researchers have documented differences in rates of parasitism and in the consequences of parasite infection between …

The Economics Of Honey Bee (Hymenoptera: Apidae) Management And Overwintering Strategies For Colonies Used To Pollinate Almonds, Gloria Degrandi-Hoffman, Henry Graham, Fabiana Ahumada, Matthew Smart, Nick Ziolkowski

Department of Entomology: Faculty Publications

Commercial honey bee (Apis mellifera L.) colonies significantly contribute to agricultural productivity through crop pollination. Almond production requires the most colonies because there are more than a million acres of orchards that require cross-pollination for nut set. With the rising costs of managing and transporting colonies to almond orchards combined with the high colony losses beekeepers routinely experience, we asked if renting colonies for almond pollination was profitable. We conducted a longitudinal study on 190 colonies from their establishment in April until they were placed in almond orchards 10 mo later. In the fall, equal numbers of colonies were placed …

External Marking And Behavior Of Early Instar Helicoverpa Armigera (Lepidoptera: Noctuidae) On Soybean, Luiz E. R. Pannuti, Edson L. L. Baldin, Silvana L. Vieira De Paula Moraes, Thomas E. Hunt, Vinicius F. Canassa, José P. F. Bentivenha, Ivana F. Da Silva

Department of Entomology: Faculty Publications

Helicoverpa armigera Hübner (Lepidoptera: Noctuidae) is a pest of major agricultural crops, such as soybean and cotton. A better understanding of larval movement is important for its integrated management and resistance management. Studies with neonates through second instar larvae are still limited by the difficulties involving the handling and observation of these instars. Many studies require marking larvae, and most research involving marking is focused on moths. However, our study investigated aspects of larval behavior of the second instar of H. armigera on soybean plants. The dyes luminous powder red and Sudan Red 7B were tested as external larval …

Developmental Parameters Of Spodoptera Frugiperda (Lepidoptera: Noctuidae) Immature Stages Under Controlled And Standardized Conditions, Débora Goulart Montezano, Alexandre Specht, Daniel Ricardo Sosa-Gomez, Vânia Ferreira Roque-Specht, Silvana L. Vieira De Paula Moraes, Julie A. Peterson, Thomas E. Hunt

Department of Entomology: Faculty Publications

The fall armyworm, Spodoptera frugiperda (J. E. Smith, 1797), is the most important noctuid pest in the Americas and has recently become an invasive pest in Africa and in India. Having a detailed and standardized record of the biology and the larval development of S. frugiperda will be critical to further studies on integrated pest management, toxicology, and applied ecology. This study reports the temporal and morphological parameters of the immature stages of S. frugiperda for larvae fed on artificial diet under controlled conditions (25 ± 1 °C, 70 ± 10% RH and 14 hour photophase). The survival …

“Connecting Honors For All”: Reimagining The Two-Year Honors Program In The Age Of Guided Pathways, Charlotte Pressler

Honors in Practice Online Archive

Over the past three years, honors faculty at South Florida State College, a two-year college offering a limited number of workforce baccalaureates, have reinvented their program. Rather than the themed seminars and exploratory courses popular with an earlier generation, our honors courses now offer students project-based, faculty-guided opportunities for undergraduate research within our general education course sequence. Students thus participate in honors while meeting their state- and program-specific general education requirements, and they do not run the risk of jeopardizing their financial aid by incurring “excess hours.” This focus allows us to connect honors education to the vocationally oriented goals …

All For One Or Each For Her Own: Do Polygamous Families Share And Share Alike?, Kristin Mammen

Journal for the Advancement of Developing Economies

This paper examines whether the mother’s rank (whether she is a senior or junior wife) in polygamous households in Côte d’Ivoire injects favoritism that could lead to differential investment in children (based on mother’s rank), a concern that could cause an inefficient allocation of household resources. The hypothesis is that the younger is a junior wife relative to the senior wife, the greater favoritism she will receive from the husband, and the better her children will fare. This question is analyzed employing Ordinary Least Squares on a Living Standards Measurement Survey microdataset collected by the World Bank. An interesting pattern …

New Tribes, Overview And Checklist Of Neotropical Cladonotinae (Orthoptera: Caelifera: Tetrigidae), Daniela Santos Martins Silva, Oscar J. Cadena-Castañeda, Marcelo Ribeiro Pereira, Fernando Campos De Domenico, Carlos Frankl Sperber

Insecta Mundi

The Cladonotinae (Orthoptera: Caelifera: Tetrigidae) are a peculiar tetrigid taxon characterized by a relatively widened fascial carina on the frontal costa. This group currently has a doubtful taxonomic status since this is the only character shared by its members. Here, we provide an overview of the Cladonotinae reported from the Neotropical region (29 species, three of them fossils), based on the morphological examination of the specimens housed at several museums. We show that Neotropical Cladonotinae share more characteristics, which strengthen its taxonomic status, and propose two new tribes: Choriphyllini n. trib. and Mucrotettigini n. trib. We propose the new combination …
