Published: October 2006

During the 1990s, pronghorn (Antilocapra americana) populations declined in Arizona, USA. To investigate potential causes of decline, we collected blood samples from hunter-harvested male pronghorn from 2001 to 2003 on four Arizona sites. Sera were tested for antibody to parainfluenza virus type 3 (PI3), bovine viral diarrhea virus, infectious bovine rhinotracheitis virus, bovine respiratory syncytial virus, epizootic hemorrhagic disease virus (EHDV), bluetongue virus (BTV), and Chlamydia psittaci. Antibody against PI3 was found in 33% of the samples, whereas antibody against BTV/EHDV was found in 77%. Antibodies to other pathogens were found at low prevalence rates. Although pronghorn decline in Arizona is probably not directly related to disease, potential reproductive effects of BTV/EHDV and PI3 infection on pronghorn in Arizona merit further study.

Hand-rearing protocols for nondomestic ungulates used for research, zoological parks, and reintroduction to the wild are evaluated on the basis of implementation practicality, gastrointestinal disturbances, survival to weaning, and growth rates compared with those of dam-raised individuals. Although species-specific protocols utilizing milk replacers formulated for nondomestic ungulates have been reported, no such protocols have been published for pronghorn (Antilocapra americana). Five pronghorn fawns were fed Day One 30/40 Black Tail Deer plus Lactobacillus acidophilus probiotics four times per day with Day One Ultra Boost (all products from Fox Valley Animal Nutrition, Inc, Huntley, IL 60142, USA) added at one feeding per day and weighed twice per week for up to the first 16 wk of life.

EVALUATION OF ETORPHINE-MEDETOMIDINE-MIDAZOLAMAZAPERONE FOR IMMOBILIZATION IN CAPTIVE PRONGHORN ().

Etorphine based immobilization protocols are reported to be effective in pronghorn; however, information on cardiorespiratory effects is limited. The objective of this study was to evaluate the efficacy and cardiopulmonary effects of etorphine, medetomidine, midazolam, and azaperone for immobilization in captive pronghorn. Additionally, the effects of endotracheal intubation and manual ventilation on cardiopulmonary variables were assessed.

Prevalence and Diversity of Piroplasms in Free-ranging Ruminants in Nevada, USA.

J Wildl Dis

November 2024

Southeastern Cooperative Wildlife Disease Study, 589 D. W. Brooks Dr., Athens, Georgia 30602, USA.

Article Synopsis
  • Wildlife hosts a variety of piroplasm species that can impact both domestic animals and public health, highlighting their ecological significance.
  • A study in Nevada tested 447 ruminants, finding 115 positive for piroplasms, with the highest infection rates among mule deer, followed by bighorn sheep and elk.
  • Four species of piroplasms were identified, with Babesia duncani being the most prevalent, indicating significant diversity and potential zoonotic risks among free-ranging ruminants in the area.

Background: Climate is an important driver of ungulate life-histories, population dynamics, and migratory behaviors. Climate conditions can directly impact ungulates via changes in the costs of thermoregulation and locomotion, or indirectly, via changes in habitat and forage availability, predation, and species interactions. Many studies have documented the effects of climate variability and climate change on North America's ungulates, recording impacts to population demographics, physiology, foraging behavior, migratory patterns, and more.
