Topic:Equids

Equids are members of the family Equidae, which includes modern horses, donkeys, and zebras, as well as extinct species. Equids are characterized by their long limbs, single-toed hooves, and herbivorous diet, which is primarily composed of grasses. Horses, specifically, have been domesticated for thousands of years and have played significant roles in agriculture, transportation, and sport. This page compiles peer-reviewed research studies and scholarly articles that explore various aspects of equids and horses, including their evolution, physiology, behavior, and interactions with humans. The collected works provide insights into the genetic diversity, adaptive traits, and conservation efforts related to equid species.
‘First record of Hsiungia pekingensis (Nematoda: Strongylidae) in North America: Morphological and molecular identification of a rare equine strongyle.
Journal of helminthology    February 24, 2025   Volume 99 e35 doi: 10.1017/S0022149X25000185
Mohtasebi S, Ahn S, Rosa B, Moyes K, Kuzmina TA, Gilleard JS, Poissant J.Equids are infected by a diversity of gastrointestinal nematode parasites, including 64 species of equine strongyle nematodes from19 genera. Despite numerous surveys of horse strongyles worldwide, certain geographic regions and rare species remain understudied. In 1964, a new species of equine strongyle, Cylicocyclus pekingensis, was described from a donkey in China. Subsequently, this species was recorded in horses from Kazakhstan and reclassified as Hsiungia pekingensis (K'ung and Yang, 1964), the only species in this genus. Since then, H. pekingensis has not been reported elsewhere, with li...
Equine neutrophils selectively release neutrophil extracellular traps in response to chemical and bacterial agonists.
Frontiers in veterinary science    February 24, 2025   Volume 12 1512343 doi: 10.3389/fvets.2025.1512343
Sheahan BJ, Schubert AG, Schubert W, Sheats MK, Schnabel LV, Gilbertie JM.Neutrophil extracellular traps (NETs) play a significant role in response to a variety of infectious and inflammatory stimuli in human and veterinary medicine. Although entrapment of bacteria can be an important function of NETs, the exuberant release of DNA and other intracellular molecules has also been negatively implicated in the pathogenesis of different diseases. Thus, NET formation must be tightly controlled and represents an opportunity for therapeutic interventions. Horses are particularly sensitive to bacterial stimuli that have previously been shown to cause NETs in other species, b...

Veterinary parasitology    February 23, 2025   Volume 335 110425 doi: 10.1016/j.vetpar.2025.110425
de Freitas MG, Dos Santos GH, Silva DLZ, Costa TD, Borges DGL, Reckziegel GH, Cleveland H, do Nascimento Ramos CA, Pereira FB, de Almeida Borges F.The strategic control of equine gastrointestinal nematodes is based on epidemiology. The aim is the reduction of the population of parasites as a whole in the hosts and environment while seeking the number of treatments that achieves the balance between not risking animal health and not exerting selection pressure for resistant parasites. This is the first study in a tropical region to assess a strategic control protocol for equines. The study was conducted in the municipality of Anastácio in the state of Mata Gross do Sul, Brazil, over a two-year period from April 2021 to March 2023, involvi...
Nay to Prey: Challenging the View of Horses as a “Prey” Species.
Animals : an open access journal from MDPI    February 22, 2025   Volume 15, Issue 5 641 doi: 10.3390/ani15050641
Steklis NG, Peñaherrera-Aguirre M, Steklis HD.This paper challenges the prevalent characterization of domesticated horses as prey species that inherently view humans as predators. Drawing on evolutionary, ethological, and cognitive evidence, we propose the "mutualistic coevolution hypothesis", which posits that horses and humans have evolved a partnership marked by cooperation rather than fear. We critically assess the "prey hypothesis", emphasizing a predator-prey model, which dominates equine training and the literature, and we argue that it inadequately explains horses' morphology, behaviors, and cognitive capacities. Comparative studi...
Investigation of the occurrence of low thyroxine concentrations and response to thyrotropin-releasing hormone using equine and canine assays in a population of Standardbred racehorses in Prince Edward Island, Canada.
Journal of equine veterinary science    February 21, 2025   105400 doi: 10.1016/j.jevs.2025.105400
MacMillan KM, Burns JJ, John E, Clancey N, Stull JW.Decreased total T4 (tT4) concentrations are frequently observed in racing Standardbred horses lacking clinical evidence of hypothyroidism. This poses a diagnostic challenge as primary hypothyroidism is reported to be rare in adult horses. Despite this, owners frequently wish to administer thyroid supplementation to horses having low tT4 concentrations. Forty racing Standardbred horses were sampled. Baseline tT4 concentrations were determined using human-based (equine) and canine-based chemiluminescent assays. Dynamic evaluation of tT4 was performed using a thyrotropin-releasing hormone (TRH) s...

Risvanli A, Hatipoglu F, Salykov R, Timurkaan N, Kadiralieva N, Kasymalieva KK, Seker I, Ekinci E.In the current study, we aimed to determine the distribution of telocytes in the ovary, oviduct and uterus of Kyrgyz mares depending on whether they were pregnant. We also studied the progression during the first 6 months of pregnancy. To this end, ovary, oviduct and uterus tissues from 53 Kyrgyz mares were obtained post-mortem. The mare tissue samples were divided into two groups: pregnant (n = 43) and non-pregnant (n = 10). Telocyte levels in the tissues were determined using light microscopic and immunohistochemical methods. Subsequently, the data acquired were evaluated based on ...
Through a Horse’s Eyes: Investigating Cognitive Bias and Responses to Humans in Equine-Assisted Interventions.
Animals : an open access journal from MDPI    February 19, 2025   Volume 15, Issue 4 607 doi: 10.3390/ani15040607
Rochais C, Akoka E, Amiot Girard S, Grandgeorge M, Henry S.Animal-assisted interventions (AAIs) have become increasingly popular, with horses being one of the most commonly used species. While the effects of equine-assisted interventions (EAIs) have been widely studied in humans, research focusing on animals involved in such work is limited. Understanding how animals perceive their world is ethically important because their perception reflects the valence of their underlying mood. We investigated the cognitive judgement bias (pessimistic vs. optimistic) and perception of humans (negative vs. positive) in horses from three different facilities, divided...
Anthropomorphizing with Critical Reflexivity: The Danger and Potential of Anthropomorphizing in Equine-Facilitated Learning and Psychotherapy.
Animals : an open access journal from MDPI    February 19, 2025   Volume 15, Issue 4 605 doi: 10.3390/ani15040605
John KD, Vincent AL, Nieforth LO, Schafroth J.This article used an intersectional feminist analytic framework to theorize the role of anthropomorphizing human-equine interactions in the HERD Institute's modality for practitioners of Equine-facilitated learning and equine-facilitated psychotherapy (EFL/P). EFL/P is a traditionally human-centered activity which leverages anthropomorphizing equine behavior and emotions to better understand human selves and dynamics by assigning human emotions to equids and human-equine interactions. Intersectional feminist theories were used to interpret 11 in-depth interviews with EFL/P practitioners. The d...
Campylobacter jejuni hepatitis in a horse: case report and literature review. Macías-Rioseco M, Ochoa J, Choi EA, Blanchard P, Moeller RB, Uzal FA. spp. can cause gastroenteritis, hepatitis, bacteremia, and abortions in domestic animals and humans. Some spp. are zoonotic. To our knowledge, hepatitis caused by has not been reported in horses. Here we present a case of acute necrosuppurative hepatitis caused by infection in a 3-y-old gelding, and we review the literature on infections in various animal species.

A missense mutation in the KCNE4 gene is not predictive of equine anhidrosis.
Animal genetics    February 16, 2025   Volume 56, Issue 1 e70004 doi: 10.1111/age.70004
van der Graaf L, Leigh W, Szmatoła T, Roberts K, Ryan S, Brown B, Van Buren S, Finno CJ, Petersen JL.Anhidrosis is defined as a decreased or absent ability to sweat in response to heat and exercise. In horses, this condition can increase the risk of life-threatening hyperthermia. A prior study has suggested that equine anhidrosis is associated with a missense variant (rs68643109) in the Potassium Voltage-Gated Channel Subfamily E Regulatory Subunit 4 (KCNE4) gene. This project aimed to validate this association in a population of well-phenotyped horses and to determine the allele frequency of this variant in publicly available whole-genome sequence data. Fifty horses within the University of ...
Unveiling the equine placental transcriptome: A novel study on ICSI-derived pregnancies.
Theriogenology    February 16, 2025   Volume 237 120-128 doi: 10.1016/j.theriogenology.2025.02.013
Fedorka CE, Scoggin KE, Coleman SJ, Hatzel JN, Burleson MD, Troedsson MHT.Alterations during the early stages of embryo development have been associated with long-term effects on the fetus, neonate, and adult, but this has not been investigated in horses. In recent years, intracytoplasmic sperm injection (ICSI) has gained in commercial popularity in the equine population. Research suggests an association between ICSI-produced embryos and placental malformations, but there exists little understanding of the physiology involved. Therefore, we aim to produce a complete transcriptomic analysis of chorioallantois and provide potential pathways that may be impacted follow...

Evaluating plasma lactate running speed derived parameters for predicting maximal lactate steady state in teaching horses.
Journal of equine veterinary science    February 14, 2025   105385 doi: 10.1016/j.jevs.2025.105385
Littiere TO, Costa GB, Sales NAA, Carvalho JRG, Rodrigues IDM, Ramos GV, Ferraz GC.In humans, there is an ongoing academic discussion about measuring plasma lactate concentration ([La]) during an incremental exercise test (IET) to establish thresholds that can predict the maximal lactate steady state (MLSS). Training studies on horses have utilized the onset of [La] (OBLA), also known as V, the velocity at which the [La] of 4 mM is reached. This study assesses the effectiveness of four methods for estimating the MLSS in teaching horses. Ten teaching horses underwent a single IET to determine four exercise intensity thresholds for predicting MLSS and performed several constan...
DSP-1, the major fibronectin type-II protein of donkey seminal plasma is a small heat-shock protein and exhibits chaperone-like activity against thermal and oxidative stress.
Biochimica et biophysica acta. Proteins and proteomics    February 14, 2025   141064 doi: 10.1016/j.bbapap.2025.141064
Alim S, Cheppali SK, Pawar SS, Swamy MJ.Fibronectin type-II (FnII) proteins are major constituents in the seminal plasma of many mammals and play a crucial role in sperm capacitation. Additionally, the seminal FnII proteins from bull and horse exhibit chaperone-like activity (CLA), by acting as small heat shock proteins (shsps). The present work demonstrates that the major FnII protein of donkey seminal plasma, DSP-1 exhibits CLA with broad specificity and protects various client proteins such as alcohol dehydrogenase, lactate dehydrogenase and enolase against thermal and oxidative stress. Binding of phosphorylcholine (PrC) - the he...

Measuring Noseband Tightness on the Lateral Aspect of the Horse’s Face.
Animals : an open access journal from MDPI    February 13, 2025   Volume 15, Issue 4 doi: 10.3390/ani15040537
MacKechnie-Guire R, Clayton H, Williams J, Marlin D, Fisher M, Fisher D, Walker V, Murray R.Measuring tools designed to objectively determine equine noseband tightness are inserted on the dorsal nasal planum in a rostro-caudal direction. The lateral aspect of the horse's head has several areas where minimal soft tissue intervenes between the skin and underlying bone, which makes them potentially useful sites for measuring noseband tightness. One hundred horses were fitted with a snaffle bridle with a cavesson, Swedish or dropped noseband in random order. The tightness of each noseband type was adjusted sequentially to 2.0, 1.5, 1.0, 0.5 and 0.0 finger-equivalents using an ISES Taper ...

Time but not storage of equine plasma in silicate-coated tubes affects adrenocorticotropic hormone stability.
American journal of veterinary research    February 6, 2025   1-5 doi: 10.2460/ajvr.24.11.0362
Johnston TJ, Stewart AJ, Dryburgh EL, Bertin FR.Pituitary pars intermedia dysfunction (PPID) is diagnosed by measuring the ACTH concentrations. Due to the reported instability of ACTH, it is recommended to transfer centrifuged plasma into cryovials; however, in practice, cryovials are infrequently used, and serum (red-top) tubes are used instead. This study investigated whether this procedure affects ACTH concentrations and the diagnosis of PPID. Unassigned: This was a cohort study. Blood was collected into EDTA tubes from 9 horses with PPID and 7 controls. After centrifugation, plasma was either aliquoted into a cryovial or into a serum tu...
