Acute hemorrhage and death in calves following chlorophacinone exposure

Three calves were submitted to the Iowa State University Veterinary Diagnostic Laboratory for diagnostic evaluation following an abrupt increase in morbidity and mortality in a calf herd associated with epistaxis and widespread hemorrhage. Each of the submitted calves had moderate-to-severe hemorrhage within various tissues and body cavities, including the thymus, subcutaneous region of the neck, mediastinum, lungs, pericardial sac, heart, spleen, perirenal fat, urinary bladder, and skeletal muscle, including the diaphragm. An anticoagulant rodenticide screen was performed on the livers of each calf. Significant concentrations of chlorophacinone were detected at 4.2, 3.6, and 2.9 ppm in liver. Multiple piles and an open pail of white powdery material were present within the facility in which the calves were housed and were identified as the sources of chlorophacinone. Acute hemorrhage and death occurred in fourteen 1.5-mo-old, crossbred calves following ingestion of the vitamin K antagonist chlorophacinone.

Undergraduate Certificate in Swine Production Management

Iowa State University (ISU) offers undergraduate certificates to demonstrate completion of a focused study in a specialized area across a variety of disciplines. The certificate has the significant benefit of allowing students to customize their curriculum and document an approved course of study. A Swine Production Management Certificate is now offered within the Animal Science Department at ISU. The certificate requirements are organized to correspond with faculty and employer-defined needs for a successful transition from ISU student to swine industry professional.  The Swine Production Management certificate will integrate technical topics in animal science with practical considerations in enterprise management. Two critical components to the certificate are the capstone Swine Systems Management course and a required internship with a focus on swine production management. Students that complete the certificate will have the background to identify and address challenges in modern swine production enterprises. Further, the certificate assists employers in identifying students that have shown the interest, discipline, and ability to complete this specialized study program.

Iowa State University Beef Teaching Herd Feed efficiency selection – year 1

Over the past 15 years there have been a numberof research and extension efforts directed towards the improvement of feedefficiency in beef cattle.  This efforthad always involved herds other than the actual university’s herd, but now theuniversity’s teaching herd has been enrolled and the developments will be madeavailable as time moves on for the public to follow.

University Implementation of TEACHActive – An Automated Classroom Feedback System and Dashboard

Computer vision has the potential to play a significant role in capacity building for classroom instructors via automated feedback. This paper describes the implementation of an automated sensing and feedback system, TEACHActive. The results of this paper can enable other campuses to replicate a similar system using open-source software and consumer-grade hardware. Some of the challenges discussed include faculty recruitment, IRB procedures, camera-based classroom footage privacy, hardware setup, software setup, and IT support. The design and implementation of the TEACHActive system is being carried out at Iowa State University and is being tested with faculty in classrooms pilots. Preliminary interviews with instructors show a desire to include more active learning methods in their classrooms and overall interest in a system that can perform automated feedback. The primary results of this paper include lessons learned from the institutional implementation process.

In Memoriam: Linda Catherine Schmidt (1958-2021)

Professor Linda Schmidt, a pioneering leader in engineering design research and education, passed away on March 12, 2021. She was born in Blue Island, Illinois on November 27, 1958, and received her B.S. degree (1989) and M.S. degree (1991) in Industrial Engineering from Iowa State University before going on to complete her Ph.D. degree in Mechanical Engineering from Carnegie Mellon University in 1995. She was one of Professor Jonathan Cagan's early Ph.D. students. Her dissertation entitled “An Implementation Using Grammars of an Abstraction-Based Model of Mechanical Design for Design Optimization and Design Space Characterization” was foundational to her early investigations.

Automating Uniformity Trials to Optimize Precision of Agronomic Field Trials

Plot size has an important impact on variation among plots in agronomic field trials, but is rarely considered during the design process. Uniformity trials can inform a researcher about underlying variance, but are seldom used due to their laborious nature. The objective of this research was to describe variation in maize field trials among field plots of varying size and develop a tool to optimize field-trial design using uniformity-trial statistics. Six uniformity trials were conducted in 2015–2016 in conjunction with Iowa State University and WinField United. All six uniformity trials exhibited a negative asymptotic relationship between variance and plot size. Variance per unit area was reduced over 50% with plots 41.8 m2 in size and over 75% when using a plot size >111.5 m2 compared to a 13.9 m2 plot. Plot shape within a fixed plot size did not influence variance. The data illustrated fewer replicates were needed as plot size increased, since larger plots reduced variability. Use of a Shiny web application is demonstrated that allows a researcher to upload a yield map and consider uniformity-trial statistics to inform plot size and replicate decisions.

Cautery Disbudding Iron Application Time and Brain Injury in Goat Kids: A Pilot Study

Cautery disbudding is a painful procedure performed on goat kids to prevent horn growth that may result in brain injury. Thermal damage to the cerebral cortex of the brain and subsequent neurologic disease is a primary concern. Cautery iron application time may affect transmission of heat to the brain; however, research in this area is scarce. Therefore, the objective of this pilot study was to evaluate the effect of iron application time on brain injury of goat kids. A total of six buck and doe kids <9 days of age were obtained from a commercial dairy and transported to an Iowa State University research facility. Kids received a different randomly assigned application time (5, 10, 15, or 20s) on each horn bud. Kids were disbudded using an electric cautery iron (under isoflurane general anesthesia). After a 5-day observation period, the kids were euthanized, and magnetic resonance (MR) images were acquired to evaluate brain injury. Additionally, four of the six kids were presented for gross examination and two kids were selected for histopathologic examination. From the MR images, white matter edema was observed subjacent to four treated areas, representing application times of 5 s (one horn bud), 15 s (one horn bud), and 20 s (two horn buds). With the exception of the horn bud that received 5 s, which had white matter edema restricted to a single gyrus, the remaining three groups had a branching region of edema. No bone abnormalities were identified on any kids. Gross evidence of discoloration and hemorrhage on the cerebral hemispheres was observed on two horn buds that received 20 s, two horn buds that received 15 s, and one horn bud that received 10 s. Microscopic lesions consisting of leptomeningeal and cerebrocortical necrosis were observed in sections of brain from all groups. Lesions were most severe with 20 s. In conclusion, all application times used in this study resulted in some level of brain injury; however, using 15 s or more resulted in more severe and consistent brain injury. These results indicate that extended iron application time may increase the risk of brain injury in cautery disbudded kids.
