Abstract:
Epitheliogenesis Imperfecta (EI) is a mechanobullous disease that occurs in newborn American Saddlebred and Belgian Draft foals. Necropsy evaluations of two American Saddlebred foals revealed broad skin lesions, dental abnormalities and oral mucosa lesions. Construction of a partial pedigree showing occurrences of EI in American Saddlebred horses was consistent with a recessive pattern of inheritance. An allelic frequency of 0.04 was estimated for the EI gene. The pathological signs of EI were similar to a disease in humans known as Herlitz Junctional Epidermolysis Bullosa (HJEB). HJEB is caused by a defect in one of the three subunits of the laminin 5 protein (LAM 3, LAM 3 and LAM 2), which leads to a separation of the epidermis from the dermis. Transmission electron microscopy revealed a separation within the lamina lucida at the sites of epidermal/dermal splits in the skin of EI affected foals. This indicated that a defect in the laminin 5 protein was responsible for EI. Linkage disequilibrium (LD) between microsatellite markers and the EI disease locus was tested for in the American Saddlebred and Belgian Draft breeds. Genotyping of microsatellite alleles was used to determine fit to Hardy-Weinberg equilibrium for control and EI populations for both breeds using Chi square analysis. Two microsatellite loci (ASB14 and AHT3) were not in Hardy-Weinberg equilibrium in EI affected American Saddlebred horses. This suggested that the EI disease locus was located on ECA 8, the putative location of LAM 3. No evidence of LD between any of the tested microsatellite loci and the EI locus was observed in the Belgian Draft samples. A cDNA library was built from Thoroughbred horse skin to serve as a resource for sequencing equine skin gene transcripts. 313 ESTs were sequenced, of which 207 were putatively identified (66%) by database search. Examination of the pathology and ultrastructure of EI affected foals and comparison with HJEB indicated that laminin 5 was the responsible defective protein. The LD analysis suggested that LAM 3 was the EI disease locus in American Saddlebred horses.

Abstract:
The social intelligence hypothesis states that the main selection pressures driving increases in brain-to-body ratio are social rather than ecological. The domestic horse is an ideal animal to study within this framework because horses possess rich social lives but inhabit simple ecological environments. Here I assess the abilities of horses within two broad areas of social cognition; the classification of, and the use of information obtained from, social partners. In Section One I demonstrate that horses are capable of cross-modal individual recognition of conspecifics, an ability not previously demonstrated conclusively outside of humans. This ability extends to identifying familiar human companions suggesting that recognition systems are highly plastic in the individuals they can encode. These results also provide the first insights into the brain mechanisms involved in this process by revealing a clear left hemisphere bias in discriminatory ability. In Section Two I investigate the extent to which horses are capable of reading human attentional and communicative cues. It has been suggested that this skill was selected for through the process of domestication, however there have been no systematic studies of domestic animals other than the domestic dog. I found that horses were indeed highly skilled at determining if people were paying attention to them. In contrast they tended to only use basic stimulus enhancement cues to choose a rewarded bucket. A further study of young horses indicated that the ability to detect human attention requires significant experience to develop fully whereas the ability to use stimulus enhancement cues in an object choice task appears to require far less (if any) experience to develop. Overall my thesis extends our knowledge of comparative social cognition and in particular our knowledge of social cognition in horses. Taken together, these results clearly demonstrate that horses do indeed possess some complex socio-cognitive skills.

El objetivo del presente estudio fue determinar la seroprevalencia del virus Herpes Equino tipo 1 (VHE-1) / virus Herpes Equino tipo 4 (VHE-4), en caballos de diferentes departamentos del Perú. Se colectaron muestras de suero (n=825) de caballos mayores a 6 meses de edad entre machos y hembras de apariencia normal dedicados a distintas actividades como caballo de carrera, caballo peruano de paso, caballo de deporte, caballo de trabajo o tiro, para la detección de anticuerpos neutralizantes contra el VHE-1/VHE-4 mediante la prueba de neutralización viral. El 48.9 ± 3.4% (403/825) de las muestras tuvieron anticuerpos contra el VHE-1/VHE-4. Los anticuerpos fueron detectados en los caballos procedentes de todos los departamentos con prevalencias similares, con la única excepción de Madre de Dios con un 0% (0/5) de seroprevalencia. Los títulos de anticuerpos tuvieron un rango entre 1:2 a >1:256, siendo los títulos de 1:2 a 1:8 presentes en el 58.6% de las muestras, los de 1:16 a 1:64 en el 29.5% y los títulos de 1:128 a > 1: 256 en el 11.9% de las muestras. La prueba de regresión logística indicó que la variable sexo no constituye un factor de riesgo para la presentación de anticuerpos contra el VHE-1/VHE-4. En cuanto al tipo de actividad, los caballos de carrera, caballos peruano de paso y los dedicados al deporte constituyeron factores de riesgo de 8.8, 3.2 y 2.3 veces más de tener anticuerpos contra el VHE-1/VHE-4, respectivamente en comparación con los hallazgos en caballos de trabajo.

Abstract:
This study was undertaken to evaluate fertilization and early embryo development of in vitro matured (IVM) horse oocytes following transfer with homologous sperm to the oviduct of estrous ewes. A total of 1023 follicles (5.1 per ovary) were found after processing 202 slaughterhouse ovaries by aspiration and subsequent slicing. Most follicles (79%) were less than 20-mm in diameter. Six hundred sixty-seven oocytes were recovered (3.3 per ovary; recovery rate, 65%). About two-thirds of oocytes were recovered by slicing, which yielded twice the number of oocytes as aspiration. Sixty four percent cumulus oocyte complexes (COCs) recovered by each method were grade A and the overall distribution of oocytes by grade was not affected by the method of recovery. Oocytes underwent IVM for an average of 41-h and were subjected to either in vitro fertilization (IVF) or xenogenous gamete intrafallopian transfer (XGIFT). At the onset of IVM, 83% COCs had compact cumulus investment. At the end of IVM, 78% COCs showed cumulus expansion. The expansion score was not improved with increasing the IVM duration from 32.3 to 50.3 h. Five (15%) IVF oocytes showed changes indicative of fertilization and two cleaved to 3 and 4-cell stages. Oviducts of 16 ewes were use for XGIFT, which involved surgical transfer of an average of 13 oocytes with 40x103 capacitated spermatozoa per oocyte. Of 259 oocytes transferred, 36 (14%) were recovered between 2 to 7 d post XGIFT and 13 (36%) showed cleavage ranging from the 2-cell to hatching blastocyst stage. The ovarian status of ewes and ligation of the uterotubal junction (UTJ) at the time of XGIFT, or the duration gametes were allowed to reside in the uterine tube, did not affect the recovery and cleavage rate. However, the most advanced stage embryos were recovered from ewes ovulating shortly after XGIFT. Fertilization following XGIFT was further demonstrated by the detection of ZFY loci in one embryo. This study demonstrated, for the first time, that horse embryos could be produced in a non-equine species. However, further studies focusing on the establishment of pregnancy in the mare using such embryos and improvement of the recovery and fertilization rates following XGIFT are recommended for use of XGIFT in horse assisted reproduction.

El presente trabajo se llevó a cabo para determinar la prevalencia de parásitos gastrointestinales en caballos (Equus caballus) pertenecientes a la Subdirección de la unidad de montados, caninos y grupos de apoyo al medio ambiente unidad Zinacantepec, de la Comisión Estatal de Seguridad del Estado de México. Para la realización de dicho trabajo se analizaron las muestras fecales de 40 equinos, las cuales fueron tomadas directamente del ano para su posterior identificación, registro y análisis en los laboratorios del Centro de Investigación y Estudios Avanzados en Salud Animal (CIESA) de la FMVZ-UAEMex, las muestras fueron procesadas mediante las técnicas coproparasitoscópicas de concentración por flotación, sedimentación simple y Mc Master. Los resultados de los análisis coprológicos evidenciaron que el 72.5% (29/40) de los caballos que fueron muestreados y procesadas las muestras mediante técnica de concentración por flotación presentan algún tipo de parasitismo, siendo el 37.93% (11/29) una infestación por un solo tipo de parasito; Trichostrongylus spp 13.79% (4/29), Strongylus spp 13.79% (4/29), Trichonema spp 6.89% (2/29), Parascaris equorum 3.44% (1/29) y el 62.06% (18/29) una infestación mixta; Trichonema spp + Trichostrongylus spp 27.58% (8/29), Trichonema spp + Strongylus spp 6.98% (2/29), Trichonema spp + Parascaris equorum 6.89% (2/29), Trichostrongylus spp Strongylus spp 10.34% (3/29), Trichostrongylus spp + Parascaris equorum 3.44% (1/29) y Strongylus spp + Parascaris equorum 6.89% (2/29). La técnica de sedimentación simple se llevó a cabo con el objetivo de identificar huevos de trematodos, específicamente Fasciola hepática evidenciando el 100% de negatividad. El conteo de huevos por gramo de heces (hpgh) fue realizado mediante la técnica de Mc Master a muestras que dieron como positivo a algún tipo de parásito mediante la técnica de concentración por flotación, teniendo como resultado un rango en el total de la población muestreada de entre 300 a 800 hpgh. Estos resultados parecen indicar fallas en los programas de prevención y control de parásitos, además de una posible resistencia parasitaria a los desparasitantes de uso convencional. En conclusión, se reportó una alta prevalencia de parásitos gastrointestinales en los equinos muestreados.

Smith, Amy Victoria. "Responses of domestic horses (Equus caballus) to human emotional signals." Thesis, University of Sussex, 2017. http://sro.sussex.ac.uk/id/eprint/70055/.

Abstract:
The communication of emotion is fundamental for social cohesion and information sharing in social species. It may be highly beneficial for domestic animals to recognise human emotional signals, as this would allow them to make informed decisions about their interactions with humans, and about events in human-dominated environments. To date, the literature in this area has largely focused on domestic dogs' (Canis familiaris) abilities. The present thesis extends this field of research to include domestic horses (Equus caballus), which represent an appropriate alternative study species due to their close co-evolutionary history with humans, their high natural levels of sociality, and their established abilities to respond to a range of other, non-emotional social signals of humans. Previous research into horses' abilities to read human emotions has produced mixed results, and too few studies have been conducted to draw firm conclusions. This thesis presents a series of behavioural experiments that investigate horses' responses to human emotional expressions when presented as isolated cues: photographs showing facial expressions of anger and happiness (Article I, Part i and ii); photographs showing facial expressions of fear, happiness, and neutrality (Article II); audio files of emotional vocalisations depicting happiness and anger (Article III); and live human actors displaying body postures of dominance and submissiveness (Article IV). The results reveal that horses show aversive behavioural and physiological responses towards angry facial expressions; behavioural attractions towards fearful facial expressions (possibly due to the function of fear in appeasement); an increased vigilance towards angry vocalisations, as indicated by freeze behaviour; and preferences for approaching submissively postured humans. This thesis therefore demonstrates that horses respond appropriately to a range of human emotional signals without prior training, which may have theoretical implications for investigating the flexibility of emotion perception across species, and applied interest for horse management and welfare.

Este trabalho analisa a din?mica social de um grupo de ?guas em tr?s dimens?es: di?dica, tri?dica e coletiva. Est? dividido em tr?s Cap?tulos cujos objetivos s?o: 1) descrever intera??es di?dicas afiliativas e agon?sticas e caracterizar a din?mica social de parcerias preferenciais; 2) analisar ocorr?ncias e intera??es em conflitos (interven??es de terceiros) e p?s-conflitos (reconcilia??o, consolo e apaziguamento) e 3) caracterizar a din?mica de movimentos coletivos sob an?lises de fatores pr?prios do indiv?duo (idade, peso, ranque e estado reprodutivo). O estudo foi realizado no Haras Volta (Frei Paulo, SE, Brasil) em 2012 e 2013. Foi observado um grupo de 64 ?guas e 20 potros lactentes da ra?a manga-larga machador. Foram realizadas tr?s tipos de observa??es diurnas: 1) focal (ocorr?ncias de comportamentos agon?stico, afiliativos, sincronia e mudan?a de dire??o = 130 horas); 2) todas as ocorr?ncias de conflitos em 304 h e 3) varreduras (posicionamento e atividade = 117 varreduras) que geraram informa??es de proximidade (valor da rela??o), rede social e dist?ncias entre os animais. No Cap. 1 descreveu-se que as ?guas se envolveram mais em afilia??o do que em agonismo. ? poss?vel que a sincronia na dire??o possa ser um tipo de afilia??o tamb?m nessa esp?cie. ?guas mais velhas e mais pesadas tiveram ranques mais elevados, mas n?o houve categoria mais agressiva que outra. Parceiras preferenciais apresentaram similaridade em idade, peso, for?a nos relacionamentos e centralidade social, sendo que a din?mica social dessas parcerias caracterizou-se por proximidade e baixo agonismo entre parceiras. A afilia??o e a sincronia foram mais direcionadas para animais neutros do que para parceiras preferenciais. No Cap. 2 reportou-se que reconcilia??o, consolo/apaziguamento e interven??o em conflitos (IC) ocorreram em 57%, 37% e 31% dos conflitos, respectivamente. A ocorr?ncia de reconcilia??o ou dispers?o, realizadas pelas d?ades com e sem reconcilia??o, respectivamente, podem ser estrat?gias para redu??o da incerteza/instabilidade social p?s-conflito. Os conflitos ocorreram entre ?guas com pouca proximidade e reconcilia??o n?o foi dependente do valor da rela??o (amizade), mas o consolo e apaziguamento foram. A interven??o em conflitos foi realizada por ?guas com idade e ranque mais elevados que os das oponentes do conflito, e n?o foi direcionada a parceiras preferenciais, sugerindo manuten??o da estabilidade social. No Cap. 3 detectou-se que n?o houve uma categoria de indiv?duos que se posicionasse com maior frequ?ncia ao centro do rebanho. ?guas mais velhas tenderam a estar ? frente do grupo. Animais mais jovens (potros) foram socialmente mais centrais e animais com necessidades nutricionais diferenciadas (prenhes e lactantes) e de alto ranque foram menos centrais socialmente. Mais da metade do rebanho esteve direcionado, com anteced?ncia, para o sentido que o grupo veio a seguir e o ?ndice de concord?ncia na dire??o (ICD) foi maior quando o grupo se deslocou mais. Isso pode sugerir que o sentido do deslocamento do grupo foi determinado pelo sentido do corpo da maioria dos animais (minimizando custos de consenso), que pode ter ocorrido por processo mim?tico de sincroniza??o, sugerindo uma forma simplificada de coordena??o (lideran?a) distribu?da em pastejo. ?guas vazias e de baixo ranque ajustaram mais suas dire??es em pastejo ? dire??o das outras ?guas. Isso indica maior ocorr?ncia de processos mim?ticos de sincronismo, o que pode levar a coordena??o do movimento ser efetuada por animais que mantenham maior consist?ncia na dire??o ou por animais mais velhos.
This study analyzes the social dynamics of a group of mares in three dimensions: dyadic, triadic, and collective. It is divided in three chapters which objectives are: 1) describe the dyadic affiliative and agonistic interactions and characterize the social dynamics of preferable partnerships; 2) analyze the occurrences and interactions in conflict (third part interventions) and post-conflicts (reconciliation, consolation, and appeasement); and 3) characterize collective movement dynamics under analyzes of individuals features (age, weight, rank, and reproductive state).The study was carried out at Volta Haras (Frei Paulo, Sergipe, Brazil) in 2012 and 2013. A group of 64 mares and 21 suckling foals of manga-larga marchador breed were observed. Three daytime methods of behavioral records were employed: 1) continuous animal-focal (registering occurrence of agonistic and affiliative behaviors, synchrony and change of direction) totaling 130 hours; 2) all occurrences of conflict in 304 hours; and 3) scan (position and activity) totaling 117 scans which generated closeness information (value of the relationship), social network, and distance among the animals. In the first chapter, we describe that the mares were more involved in affiliation than in agonisms. We suggest that synchrony in direction is a kind of affiliation in this species. Older and heavier mares had higher ranks, but there was not a category that was more aggressive than the other. Preferable partners presented similarities in age, weight, strength in the relationships, and social centrality, being the social dynamics of these partnerships characterized by closeness and low agonism among the partners. In the second chapter, we report that reconciliation, comfort/appeasement, and intervention in conflicts (IC) occurred in 57%, 37%, and 31% of the conflicts, respectively. The occurrence of reconciliation or dispersion may be strategies to reduce the social uncertainty/instability post-conflict. The conflicts occurred between mares with low closeness, and reconciliation was not dependent on the value of the relationship (friendship), but the comfort and appeasement did were. The intervention in conflicts were performed by mares with higher rank and age than the opponents of the conflict, and it was not directed to preferable partners, suggesting maintenance of the social stability. In the third chapter, we detected that there was not a category of individuals that positioned themselves to the center of the herd with higher frequency. Older mares tend to be ahead of the group. Younger animals (foals) were socially more central and animals with differentiated nutritional needs (pregnant mares and suckling ones) and high rank were less socially central. More than half of the herd was directed, with anticipation, to the direction that the group started to follow, and the agreement index in the direction (AID) was higher when the group moved more. This may suggest that the direction of the group?s movement was determined by the direction of the body of the majority of the animals (minimizing consensual costs), which may have occurred by the mimetic synchronization process, suggesting a simplified way of coordination (leadership) distributed in grazing. Empty and low rank mares adjusted more their directions in grazing towards the other mares. This indicates more occurrence of mimetic process of synchronism, which may lead to the coordination of the movement to be performed by animals that keep more consistency in direction or older animals.

Abstract:
Lateralized behaviour is the most conspicuous manifestation of hemispheric specialization of the brain and has been reported in a variety of taxa. Only a few studies have so far assessed lateralized behaviours in horses. Therefore, I observed ten domestic horses for 16 weeks for an array of spontaneously occurring motor behaviours as well as stimulus-induced behavioural responses to determine if they display side preferences at the individual or population level and to assess possible correlations between lateralized behaviours. Significant side preferences were found for certain behaviours at the individual level, ranging from standing and flexing, to auditory stimuli, and olfactory stimuli. All horses showed task-dependent changes in their side preferences and no significant side preferences were found at the population level for any behaviours. Similarly, no significant correlations were found between behaviours. Taken together, the results of the present study suggest that horses, like all other species studied so far except humans and some great apes, only display lateralized behaviour at the individual, but not at the population level.

Abstract:
Before Australia was taken over by humans more than 55 000 years BP, the landscapes were shaped through animal agency. Extinct prehistoric fauna and megafauna had social ecological systems and actively organized ecosystems and landscapes that reflected patterns of herbivory, soil foraging, nutrient cycling and predation. Surviving species continued as agents in the ecosystem functions of the EM-R region until the beginning of European colonization in the 1860’s. The settlers used the inherent biological traits of their domesticated animals, including horses, as an agency of colonization. Horses (Equus ferus caballus) who escaped to become wild are known as Brumbies in the Australian vernacular. They adapted to the local environments and prospered. This chapter analyzes the ways Brumbies have adapted to and made the land their own. It shows how they became intimately engaged with landscape details and resources which are reflected through their creation of cultural horsetrails as they moved purposefully throughout their homelands.

Abstract:
In Greek myth the winged horse Pegasus was actually ridden by the hero Bellerophon rather than by Perseus, yet Shakespeare’s words neatly capture the striking combination of supernatural power and tractability that is the horse. This chapter picks up these themes by developing three topics: it describes the evolution of the modern horse, Equus caballus, identifies key features of its biology relevant to subsequent discussions, and reviews the history of human–horse interaction in the Old World, emphasizing the horse’s domestication and subsequent spread. Horses and their relatives, the wild asses and zebras, were once seen as an almost paradigmatic example of how evolution works, although more recent research has shown that their history is more complex and multi-branched than originally thought. Along with tapirs and rhinoceroses, they belong to the taxonomic order Perissodactyla, the odd-toed division of the ungulates or hoofed mammals. The superficial similarities that they share with even-toed antelopes, which belong to the order Artiodactyla, are thus largely the result of evolution converging on similar body plans. In fact, some genetic studies suggest that perissodactyls are closer to carnivores than to the artiodactyls. Like modern tapirs and rhinoceroses, the earliest horses were three-toed, but for the past 40 million years or so all have borne their weight on just the third toe, with ligaments, rather than a fleshy pad, for support. Subsequently, the central metapodial (the bones connecting the digits to the wrist or ankle) was considerably elongated to form a long, slender lower limb and the second and fourth digits were minimized, though still giving support when galloping and jumping. Beginning around 10 million years ago, in the late Miocene period, the remaining side toes were reduced to splints and the animal’s weight came to be carried entirely on a single enlarged hoof. The first perissodactyls were browsers, not grazers. Some 45–34 million years ago, however, temperatures fell at higher latitudes and climate became more seasonal: successful ungulates evolved new adaptations, including the first appearance of both ruminants (which ferment their food in a specialized foregut) and new kinds of ancestral horses such as Mesohippus and its successor Miohippus.

Abstract:
Raising horses has become increasingly important over the years, generating great income for breeders and contributing to the economy of the entire country. Dental care with these animals occurs less frequently than necessary, which causes weakness and loss of performance in them. Infundibular disease is a dental disorder, defined as a necrotizing bacteriosis characterized by destroying the inorganic material of the dental tissues, affecting mainly the premolar and molar teeth. This pathology may predispose to other alterations such as colic syndrome, gingivitis, difficulty in feeding, and consequent weight loss, besides resistance in the adaptation to mouth movements, which cause significant losses to the breeders. Its diagnosis is made through anamnesis, general and specific clinical examination of the oral cavity, and complementary exams, such as x-ray. This paper reports the case of a 13-year-old horse weighing about 400 kg of live weight, whose chosen treatment was the extraction of the affected tooth. The study aimed to review predisposing factors, diagnosis, the effects that this clinical change can cause on the animal’s organism, and infundibular disease treatment, describing the therapy used and its results.
