Virtual Feedlot Shortcourse: When Life Hands Out Lemons, Warren Rusche

SDSU Beef Day 2021 Summary Publication

Objective
The COVID-19 pandemic forced changes in how Extension programming was delivered in 2020. Web-based distance learning tools were used to deliver educational material when it was impractical to use traditional delivery methods. Study Description
The SDSU Extension Feedlot Shortcourse has traditionally been an in-person event with as much opportunity for hands-on learning and demonstrations as possible. The program is offered over a two-day period in August at the SDSU Cow-Calf Education and Research Facility with approximately 30 participants each year, on average. The program addresses feed delivery and mixing, animal health, production technologies, and risk management. However, the events ...

Predation Of Ananteris Spp. (Scorpiones: Buthidae) By Ants And A Social Wasp (Hymenoptera: Formicidae, Vespidae) In Panama, Central America, Roberto Miranda, Luis F. de Armas, Roberto A. Cambra 2021 Marshall University

Predation Of Ananteris Spp. (Scorpiones: Buthidae) By Ants And A Social Wasp (Hymenoptera: Formicidae, Vespidae) In Panama, Central America, Roberto Miranda, Luis F. De Armas, Roberto A. Cambra

Euscorpius

Two events of predation on Ananteris spp. were observed in the Parque Nacional Darién, Darién Province, Panama. The first case involved the social wasp Agelaia centralis (Cameron, 1907) (Vespidae); the second one, a ponerine ant Leptogenys cf. cuneata Lattke, 2011 (Formicidae). This is the first time that predation by a social wasp on a scorpion is observed. They also represent the first recorded predators for Panamanian Ananteris species.

Fetilinia Dentator Gen. Et Sp. N. From Pakistan (Scorpiones: Buthidae), Graeme Lowe, František Kovařík 2021 Marshall University

Fetilinia Dentator Gen. Et Sp. N. From Pakistan (Scorpiones: Buthidae), Graeme Lowe, František Kovařík

Euscorpius

We describe from northern Pakistan a new buthid genus Fetilinia gen. n., monotypic with type species F. dentator sp. n., belonging to the Palaearctic ‘Buthus’ group. It bears some similarities to Kraepelinia Vachon, 1974, in having enlarged metasomal dentition, and to Orthochirus Karsch, 1891, and related genera in having a trapezoidal carapace and small abbreviated pedipalps.

Reports

This report describes the results of the twenty-third year of a continuing study to estimate the relative abundance and assess the status of American shad (Alosa sapidissima) stocks in Virginia by monitoring the spawning runs in the James, York and Rappahannock rivers in spring 2020, evaluating hatchery programs, and contributing to coast-wide assessments (ASMFC 2007, ASMFC 2020).

We also report on two fisheryindependent monitoring programs using anchor gillnets in the Rappahannock River (year 3) and the Chickahominy River (year 6; a major tributary of the James River), to determine relative abundance and stock structure for the adult spawning run of ...

SDSU Beef Day 2021 Summary Publication

Objective
The objective of the current study was to determine if a commercially available blood pregnancy test could be modified to detect differences in pregnancy-associated glycoprotein (PAG) concentrations to indicate stage of pregnancy or fetal age in cattle.
Study Description
Previously identified pregnant females were grouped by age (pre-primiparous or multiparous). Blood samples were collected between day 27 and 190 of pregnancy (n = 176 from pre-primiparous and n = 240 from multiparous) and serum was tested in duplicate using a commercially available blood pregnancy test, IDEXX Alertys Pregnancy Test. Procedures were adapted to allow concentrations to fall within the detectible range ...

Study Description
Angus-based cows from 2 sources [n = 129 from SDSU (Experiment 1) and n = 70 from North Dakota State University (Experiment 2)] were stratified by body weight and age and placed into two treatment groups at a drylot facility during mid- and late-gestation: Concentrate (dams fed a concentrate-based diet) or Forage (dams fed a forage-based diet). Calves were finished and carcass data was collected. Striploins were collected ...

Beef Carcass Weight And Quality Grade Influence Tenderness, Samantha R. Egolf, Austin C. Egolf, Lydia M. Hite, Christina Elaine Bakker, Amanda D. Blair, Keith Underwood, Judson Grubbs

SDSU Beef Day 2021 Summary Publication

Objective
The objective was to investigate whether hot carcass weight (HCW) affected Warner-Bratzler shear force (WBSF) and tenderness formation of Denver, strip, and eye of round steaks from USDA Select (Se) and low Choice (LC) beef carcasses.
Study Description
Select and LC carcasses were selected at a commercial beef plant by HCW (light = 650–750 lb; middle = 850–950 lb; heavy = 1,025–1,150 lb). Steaks were fabricated and aged for 5, 10, and 14 days. Tenderness was determined through WBSF based on industry standards. Additionally, protein degradation was analyzed to determine tenderness formation.

Wooden or woody breast (WB) is a myopathy of the pectoralis major in fast-growing broilers that influences the quality of breast meat and causes an economic loss in the poultry industry. The objective of this study was to evaluate growth and proteome differences between 5 genetic strains of broilers that yield WB and normal breast (NB) meat. Eight-week-old broilers were evaluated for the WB myopathy and divided into NB and WB groups. Differential expression of proteins was analyzed using 2-dimensional gel electrophoresis and LC-MS/MS to elucidate the mechanism behind the breast myopathy because of the genetic backgrounds of the ...

A Survey Of Horse Use And Management In Horse Clubs In China: A Pilot Study, Zhen Li Ph.D., Msc, Shea Porr Phd

Steeplechase: An ORCA Student Journal

Rapid development of the Chinese equine industry in the last two decades has resulted in an increased equine population without trained personnel to support industry growth. The purpose of this study was to understand the present profile of horse use in horse clubs in China from the perspective of horse welfare. The survey was distributed to specific personnel in selected Chinese horse clubs, and snowball sampling techniques were used to increase response rates. Of 20 respondents, the oldest club was established in 2002 and the newest in 2018. Fourteen clubs were membership-based, providing services for 40-1000 members and up to ...

Pharmacokinetics Of A Single Feeding Of Pelleted Cannabidiol In Horses, Anna L. Draeger, Laura K. Hoffman, Patricia R. Godwin, Amanda J. Davis, Shea A. Porr

Steeplechase: An ORCA Student Journal

Claims about cannabidiol (CBD) supplementation improving health and behavior are extensive, but research is lacking. Some studies have shown decreased anxiety behavior in rats, and increased activity in osteoarthritic dogs supplemented with CBD, but even less research exists on horses. This study monitored pharmacokinetics and short-term safety for 3 CBD dosages. Eighteen Quarter Horse geldings were randomly assigned to 3 treatment groups: 50 mg (TXT1), 100 mg (TXT2), and 250 mg (TXT3). Dosage was derived from manufacturer recommendations and existing literature on other species. Horses were fed a single dose of CBD pellets. Blood was collected pre- and post-treatment at ...

A New Vine Snake (Reptilia, Colubridae, Oxybelis) From Peru And Redescription Of O. Acuminatus, Robert C. Jadin, Michael J. Jowers, Sarah A. Orlofske, William E. Duellman, Christopher Blair, John C. Murphy

Publications and Research

The Brown Vine Snake, Oxybelis aeneus, was until recently considered a single species, distributed from southern Arizona through the Neotropics into southeastern Brazil. However, newly conducted research restructured the species with a substantial taxonomic revision, recognizing five additional taxa (i.e. O. koehleri, O. microphthalmus, O. potosiensis, O. rutherfordi, O. vittatus) in this species complex. This revision focused on populations in North America, Central America, and northern South America while neglecting the southern portion of its distribution. Here, we examine the taxonomic history of the complex and use it along with specimen data to resurrect O. acuminatus from southeastern Brazil ...
