Parenteral nutrition (PN) is one method of providing nutrient support to hospitalized, nondomestic ruminants that have a decreased appetite in hospital or have high metabolic demands caused by illness. There are a limited number of published reports of the use of PN in nondomestic ruminants. A retrospective evaluation of PN use in adult (>6 mo of age) hospitalized ruminants at the San Diego Zoo Safari Park was conducted from 2014 to 2018 ( = 24). Discharge rate for animals that received PN was 34%. Poor survival was likely caused by case selection of animals that had severe disease or malnutrition necessitating the need for PN. Common metabolic changes among the study animals included the following: hypokalemia, hyperglycemia, and hyperphosphatemia or hypophosphatemia. Bivariable analysis revealed no clinically significant factors that influenced odds of survival. There was little evidence of adverse effects with the administration of PN during the study period. Parenteral nutrition requires specialized equipment and technical skills, but is a viable means of nutrient support for hospitalized nondomestic ruminants.

COMPARISON OF HAND-REARED PRONGHORN () MILK REPLACER COMPOSITIONS AND GROWTH RATES.
J Zoo Wildl Med

Tom Thorne and Beth Williams Wildlife Research Center at Sybille, Wyoming Game and Fish Department, Wheatland, WY 82201, USA.
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.

Repetitive sequences form a substantial and still enigmatic part of the mammalian genome. We isolated repetitive DNA blocks of the X chromosomes of three species of the family Bovidae: (KDEXr sequence), (BTAXr sequence) and (ACEXr sequence). The copy numbers of the isolated sequences were assessed using qPCR, and their chromosomal localisations were analysed using FISH in ten bovid tribes and in outgroup species.

Article Synopsis
- Identifying various animal hosts involved in spill-over events of infectious diseases is essential for understanding how viruses like Lassa virus (LASV) are transmitted to humans and pose public health risks.
- Researchers conducted a study in southern Nigeria, screening domestic and non-domestic animals, including birds and lizards, to assess their potential as LASV reservoirs.
- Results showed lizards had the highest positivity rates for LASV, while cattle showed significant seropositivity, pointing to the need for further analysis of these animal hosts to inform strategies for managing Lassa fever transmission.
Domestication and breeding objective did not shape the interpretation of physical and social cues in goats (Capra hircus).

Artificial selection by humans, either through domestication or subsequent selection for specific breeding objectives, drives changes in animal cognition and behaviour. However, most previous cognitive research comparing domestic and wild animals has focused on companion animals such as canids, limiting any general claims about the effects of artificial selection by humans. Using a cognitive test battery, we investigated the ability of wild goats (non-domestic, seven subjects), dwarf goats (domestic, not selected for milk production, 15 subjects) and dairy goats (domestic, selected for high milk yield, 18 subjects) to utilise physical and social cues in an object choice task.

Cowpox virus is considered to be a re-emerging zoonotic pathogen and a public health threat due to increasing numbers of cases in humans and animals in Europe over the past decade, including within the United Kingdom (UK). We present epidemiological data and diagnostic features of 27 recent, naturally occurring cowpox cases in zoo and wild animals across the UK, including the first reports of cowpox in two snow leopards (Panthera uncia), a Bengal tiger (Panthera tigris tigris), three Chilean pudus (Pudu puda), a Malayan tapir (Tapirus indicus) and a Eurasian otter (Lutra lutra), and the first reports of Orthopoxvirus infection in a lar gibbon (Hylobates lar), a Southern tamandua (Tamandua tetradactyla) and an aardvark (Orycteropus afer). This study provides a detailed overview of cowpox infections in a wide range of non-domestic animal species, presents a range of methods for diagnosis and demonstrates the value of retrospective analysis of pathology surveillance in revealing epidemiological links.
