Livestock and horses are integral components of agricultural systems, providing resources such as meat, milk, fiber, and labor. Horses, in particular, have unique roles in agriculture, sport, and recreation, distinguishing them from other livestock. This topic explores the management, breeding, nutrition, and health of horses and other livestock species. It encompasses studies on husbandry practices, welfare considerations, and the impact of these animals on the environment and economy. The page includes peer-reviewed research studies and scholarly articles that investigate various aspects of livestock and equine science, offering insights into their biological, ecological, and economic significance.
Clutton-Brock TH, Greenwood PJ, Powell RP.Recent studies of primates have questioned the importance of dominance hierarchies in groups living under natural conditions. In a herd of Highland ponies and one of Highland cattle grazing under free-range conditions on the Isle of Rhum (Inner Hebrides) well defined hierarchies were present. The provision of food produced a marked increase in the frequency of agonistic interactions but had no effect on the rank systems of the two herds. While rank was clearly important in affecting the distribution of agonistic interactions, it was poorly related to behaviour in non-agonistic situations.
Hafs HD.Often in developing hormone assays, hormones that may interfere with the assay by cross-reaction are not available for testing the validity of the assay. For example, horse TSH was unavailable to test for cross-reaction in an LH radioimmunoassay (RIA). The authors devised an indirect means of accomplishing the same goal, and the evidence from the indirect test of cross-reaction was at least as persuasive as a direct test might have been. Other examples are given of experiments where extensive effort was devoted to validation of steroid RIA, but there were substantial quantitative differences i...
Velle W.This presentation is limited to the three groups of steroid sex hormones which alone or in combination have been shown to be anabolic when used in farm animals. It seems essential for realistic evaluation of public health aspects of use of these hormones that the discussions include naturally occurring levels of the hormones. The following topics will be dealt with for each group of hormones: 1. Types and sources; 2. Production rates; 3. Plasma levels; 4. Tissue concentrations; 5. Metabolism and excretion. Gestagens. Progesterone and 20-dihydroprogesterones are mainly produced in ovaries and p...
Young JB.An epizootic of anthrax in Eastern Falls County, Texas, killed at least 238 animals during a 6-week period ending July 31, 1974. Infection appeared to be caused by the ingestion of contaminated soil and grass in the drought-stricken central Texas area. The participation of the Texas Department of Agriculture, the Texas National Guard, and other state agencies was of great assistance to the Texas Animal Health Commission in handling the epizootic and panic stricken public. Use of the unencapsulated Sterne strain spore vaccine was credited with preventing many livestock losses in the area. Conta...
Jain NC.Comparative morphology of platelets of the dog, cat, cow, horse, sheep, and goat was studied with the scanning electron microscope and was found generally similar. Most of the platelets were slightly biconvex of flat with relatively smooth surface and even contour. Some of these platelets had few short marginal filaments, oriny protuberances on the surface. A small number of platelets exhibited surface irregularity and few long pseudopods which were thought to result from platelet activation during the processing of blood. The number os such irregular platelets increased in stored blood and in...
Goranov Kh, Ivanov V.Investigations were carried out on the alkaline phosphatase in the sera of cattle, horses, pigs, sheep, goats, and chickens, the pH value of the buffer used being 9.0-9.8-10.0-10.2-10.6 and 11.0, and the method applied--that of Richterich. The pH value at which the serum alkaline phosphatase in the various farm animals and birds was most active was found to vary to a large extent. Optimal values for the enzyme's activity usually range as follows: cattle, 10.2; pigs and goats, 10.0; sheep,--10.2; horses,--9.8; chickens,--10.6.
Mustefa A, Engdawork A, Sinke S.Ethiopian horses are multipurpose horses that have socioeconomic significance for smallholder farmers. However, studies regarding their husbandry practices have received little attention. Thus, the current study was conducted to assess the horse husbandry practices in the southwest Ethiopia. Data were collected through semi-structured questionnaires from a total of 196 randomly selected respondents. The general linear model and frequency procedures of the Statistical Analysis System (SAS 9.0) were used to analyze the quantitative and qualitative data, while indices were calculated using Micros...

Chatha MA, Ahmad N, Abbas MA, Saadullah M, Khan JA.This study was designed to explore the impact of intrinsic (breed of foal, age of dam, and age of foal at weaning) and extrinsic (season of birth and housing type) factors on the growth and survival of foals in the subtropical conditions of Pakistan. For the growth study, retrospective data analysis of foals (n = 150) born from purebred brood mares of Thoroughbred, Arabs, and Percheron breeds (n1, n2, and n3 = 50 each) was made. Six hundred and twenty-four (n = 624) foals born between 2020 to 2022 were observed for the study of foal survival rate. The survival of these foals till the age of on...
Pipereau K, Trably E, Santa-Catalina G, García-Bernet D, Carrere H.This study focuses on thermal and non-thermal effects of microwave pretreatment on horse dung as indigenous inoculum before xylose and wheat straw fermentation, emphasizing metabolite production and microbial community changes. Two horse dung microwave pretreatments (MW40°C and MW95°C) were compared with a conventional thermal pretreatment (Th95°C) and an unpretreated condition (Ctrl). Microwave heating pretreatment (MW95°C) leads to similar production as a conventional thermal pretreatment (Th95°C) for xylose and wheat straw fermentation while MW40°C treatment was similar to the control...
Martins AS, Romanowski TNA, Campos JS, Vieira RC, Silva TA, Borsanelli AC.Brucellosis is a zoonosis caused by bacteria of Brucella genus, which affects domestic and wild animals and humans. In horses, the infection can be caused by Brucella canis, Brucella suis or Brucella abortus, through the ingestion of contaminated food, contact of bacteria with skin wounds or through the respiratory tract, manifesting with signs such as fistulous withers and reduced performance. The present study aimed to evaluate the seroprevalence of Brucella abortus infection in equids in the state of Goiás. Sampling was carried out on 299 farms across 132 municipalities, with a total of 89...
Kaštovská E, Mastný J, Choma M, Čapek P, Jirků M, Bitomský M, Konvička M.Based on a growing understanding of the role of wild megafauna in the functioning of natural ecosystems, trophic rewilding by large herbivores is increasingly used as a nature-based solution to mitigate biodiversity loss and climate change in Europe and beyond. Despite the growing interest in implementing nature-based approaches to restore key non-productive ecosystem services, there is relatively little data available to assess the benefits and risks of rewilding projects. We therefore investigated the effects of year-round grazing by large ungulates on plant biomass characteristics and their...
Aldayarov N, Tulobaev A, Madumarov A, Risvanli A.While modern veterinary medicine offers effective treatments, traditional ethnoveterinary practices persist among many farming communities, reflecting centuries-old knowledge and cultural beliefs. This study aimed to document ethnoveterinary remedies and their methods of preparation and application, for treating various parasitic diseases in domestic animals used by Kyrgyz farmers. Data on plant, animal and mineral-based remedies, as well as chemicals used for these purposes, were collected through interviews with 173 dialogue partners (DPs). A total of 3403 use reports (URs) were recorded, in...

Matinpour M, Zettner N, Neumann K, Bäumer L, Burkovski A.Horses have close interactions with humans and are important as working animals and livestock. In contrast to smaller companion animals like cats and dogs, there is only little information available about their skin microbiome. The objective of this study was to identify and characterize the culturable cutaneous microbiome of healthy horses. Samples were taken from 14 horses from Southern Germany which were randomly enrolled in this study. Matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS) was used as a method to detect the culturable microorganisms of ...
Thulin CG, Chen Y, Garrido P.European grasslands and their biodiversity are declining rapidly due to land use changes, which highlight the need to develop effective restoration strategies. This study investigates the impact of reintroducing the Swedish national horse breed (the Gotland Russ) on grassland plant diversity and evenness in abandoned agricultural landscapes in Southeast Sweden. Twelve horses were introduced into three 10-13-hectare enclosure replicates (four horses per enclosure) in a three-year (2014-2016) rewilding experiment. Plant species richness, evenness, and diversity were investigated in both grazed a...
Dimuccio MM, Ceci E, Bonerba E, Celentano FE, De Marzo P, Leone R, Sportelli S, Bozzo G.The aim of this study was to evaluate cadmium (Cd) concentrations in horses imported from various European Union countries and slaughtered in Italy. In addition, we assessed the potential correlation between Cd levels in tissues and organs, and Cd-related gross and histological lesions. The animals were divided into six groups based on age and geographical origin. Among the 430 animals examined, gross renal lesions were observed in only two kidney samples from Polish horses, which also had the highest Cd concentrations: 9.1 mg/kg w/w and 8.23 mg/kg w/w, respectively. Further histological a...
Kamutzki CJ, Emmerich IU.In 2024, there was no release of a novel pharmaceutical agent for horses and food-producing animals or an extension of existing active ingredients to other animal species on the German veterinary medicinal products market. Formic acid is now available for a new form of treatment, the short-term treatment of honeybees, and clenbuterol is available in a new dosage form, as an oral solution for horses. In the field of immunological veterinary medicinal products, three new vaccines were launched on the German veterinary medicinal products market. For the first time, a vaccine against in cattle, a...
Zhang X, Abdusuli N.The horse industry constitutes a vital economic sector in Xinjiang, China. This study quantitatively assesses the sector's sustainable development through eco-efficiency analysis across northern Xinjiang counties from 2001 to 2021. The research employs four analytical methods: the S-SBM model for efficiency measurement, kernel density estimation for distribution analysis, Moran's index for spatial autocorrelation examination, and convergence tests for long-term trend assessment. Results demonstrate a consistent decline in eco-efficiency, decreasing from 0.821 in 2001 to 0.444 in 2021, with an ...
de Morais CBR, Santiago JM, da Silva AH, Nascimento DBD, de Farias IM, da Silva Dias W, Taran FMP, Lucena JEC.This study aimed to verify whether donkeys of the Nordestino ecotype are more efficient than horses concerning apparent digestibility and gas production of Tifton 85 hay at different maturity stages, using the total feces collection method and the in vitro gas production technique. Four donkeys and four horses were used in a 2 × 2 factorial completely randomized design with two Equidae species and hay at two maturity stages (higher quality "Hay 1″ and lower quality "Hay 2″). No difference (P < 0,05) was found between the Equidae species for apparent nutrient digestibility of the Hay 1....
Two new quantitative methods for the determination of four stress-related hormones (cortisol, cortisone, dehydroepiandrosterone and dehydroepiandrosterone sulfate) in horse hair and sheep wool by liquid chromatography coupled with hybrid high resolution mass spectrometry were developed and validated. Hormones were extracted overnight from ground samples with methanol after a washing step with the same solvent to remove external contamination. The extract was evaporated and dry residue was solubilized in an acid mixture of methanol and water. The methods were validated according to ICH guidelin...
Pipereau K, Trably E, Santa-Catalina G, García-Bernet D, Carrere H.Horse manure is a lignocellulosic biomass found in significant quantities with a vast indigenous flora, not yet fully valorized apart from anaerobic digestion. Its use in the fermentation process can lead to the production of higher-value metabolites. This study investigates three inoculation strategies coupled with five pretreatment conditions for horse manure fermentation. Two microwave pretreatments (200W and 1000W) were compared with a conventional thermal pretreatment, a thermo-acid pretreatment, and an unpretreated condition. The sole horse manure indigenous microorganisms were used in f...
Bianchi D, Santos RRD, Peleja PL, de Sousa ABB, da Silva Evangelista M, de Almeida Júnior JS, Barata LES, Moraes WP, Minervino AHH. (tropical horse tick) is a tick species commonly found parasitizing horses and other equids in the Amazon region, causing economic losses. Currently, tick control is based on chemical acaricides, usually in a power formulation for topical use. However, its indiscriminate use results in the emergence of resistant tick lineages. Several plant compounds have been tested for their acaricide activity. In the Amazon, several plants are used for oil extraction, resulting in the production of solid residue (waste) that may contain chemical molecules with biological activities. Thus, we aimed to test ...
de Souza Lima E, de Oliveira Filho RB, Malta KC, Pires IC, Rosa DS, Chideroli RT, Aburjaile FF, de Jesus Sousa T, Ramos RTJ, Góes-Neto A....Corynebacterium pseudotuberculosis is a bacterium that causes significant economic damage to farmers, mainly in the semiarid region of Northeastern Brazil. In this context, only biovar ovis has been reported, and it is widespread in small ruminants. However, this report describes the first equine case in Brazil attributable to a biovar equi. Clinically, it is the causative agent of ulcerative lymphangitis, mastitis, necrotic and ulcerative dermatitis. A Quarter Horse from the semiarid Northeast presented ulcerative lymphangitis. Culture, nitrate reduction test, MALDI-TOF, and whole-genome sequ...
Firdausy LW, Fikri F, Wicaksono AP, Çalışkan H, Purnama MTE.Trypanosomiasis is a vector-borne parasitic disease with significant implications for animal health and rural livelihoods in Indonesia. Despite surveillance efforts, comprehensive national-level estimates of its prevalence in domesticated animals remain lacking. This study aimed to synthesize the pooled prevalence of trypanosomiasis across Indonesian provinces, identify contributing factors, and assess trends over time using a systematic review and meta-analysis. Unassigned: A systematic search was conducted in seven electronic databases (PubMed, Scopus, Web of Science, ScienceDirect, Cochrane...
Mutillod C, Buisson E, Tatin L, Mahy G, Dufrêne M, Morvan N, Mesléard F, Dutoit T.The urgency of restoring ecosystems over vast areas has placed rewilding using wild herbivores at the forefront. However, few scientific studies address its effects on biodiversity and ecosystem functioning compared to more traditional conservation interventions with domestic herbivores. Equus ferus przewalskii horses introduced 30 years ago in the National Park of Cévennes, France - as a step of a conservation program of the species for its reintroduction in Mongolia - now occur as a semi-wild horse population, socially natural (i.e., management is based on natural selection). This introduct...
Fennouh C, Mokrani D, Dahmani H, Salhi O, Ouchetati I, Nabi M, Aouina K, Chettih I, Ouchene N, Khelifi Touhami NA.Fasciolosis, a parasitic disease of ruminants, poses significant economic and animal-health challenges in Algeria. This study aimed to assess spatial, temporal, and species-specific patterns of fasciolosis prevalence across diverse agro-climatic zones and to estimate associated economic losses. Between 2013 and 2023, eight wilayas El-Tarf, Skikda, Jijel (Region I), Blida, Mila (Region II), and M'Sila, Medea, Laghouat (Region III) were surveyed. Systematic postmortem inspections of 1,569,392 animals (349,176 cattle; 982,669 sheep; 235,639 goats; 1,882 camels; 26 horses) were performed by qualif...
Chodkiewicz A, Prończuk M, Studnicki M.In order to understand the role of horses in ecosystems and to effectively use their grazing in the protection of grasslands, it is important to assess where they primarily stay, followed by whether these habitats are used for grazing or resting. The main goal of the study was the model development based on artificial intelligence tools which allow to distinguish the basic levels of activity performed by horses using data from an accelerometer mounted in a collar worn by animals. The model calibration was based on direct observations of five randomly selected Polish primitive horse mares. In o...
Picanço EMB, Assis FFV, Peleja PL, Sousa ABB, Barrêto Júnior RA, Lima RF, Neves KAL, Minervino AHH.This study aimed to determine the prevalence of antibodies against equine brucellosis in three distinct equid groups (farm animal, urban carthorse, and sport horse) in Western Pará, Brazil, and to identify associated risk factors. A cross-sectional study, involving 75 farms across 14 municipalities, sampled 1069 equids composed of urban carthorses and sport horses. Serum samples were tested for antibodies against spp. using the buffered acidified plate antigen (BAPA) test for screening, followed by the serum agglutination in tubes with 2-mercaptoethanol (2-ME) for confirmation. Univariate an...
Andreas C.The virus that causes African horsesickness does not affect any indigenous species, but produces high mortality among horses, a species introduced by the Dutch East India Company in 1653. While the insect-borne disease did not occur in the immediate vicinity of the Cape Peninsula, horsesickness could have constituted an endemic disease barrier to the horse-based expansion of the colonial sphere into the hinterland, where it was seasonally prevalent. That it did so to only a limited extent is due to a substantial alteration of the ecology of the disease that largely resulted from inadvertent si...
Linnegar B, Hoegh A, McCallum H, Peel AJ.Anthropogenic climatic and landscape change can drive behavioural shifts in wildlife and thus lead to increased risk of pathogen exposure for humans and domestic animals. While spillover research often focuses on the reservoir hosts or ongoing transmission in humans, livestock and companion animals can play important roles as bridging and amplifying hosts, facilitating the emergence of highly pathogenic diseases. Objective: To investigate the distribution and density of domestic horses in the context of their role as bridge hosts for Hendra virus and build models to study zoonotic emergence. M...

Tang C, Yang B, Dawulietihan G, Xue L, Liu S, Yalimaimaiti Y, Wang Q, Yang N, Sun X, Wang Y, Wumaier A, Khizat S, Assanbayev T, Kozhanov Z....Xinjiang is a region renowned for its rich diversity of native horse breeds, making it one of the most affluent equine genetic resource areas in China. While prized for their high adaptability and tolerance to roughage, the conservation of these native breeds faces challenges from the introduction of external breeds and industrial changes. Furthermore, the unknown population structure of Xinjiang horse breeds has hindered effective conservation efforts. Unassigned: This study presents the first comprehensive Single Nucleotide Polymorphism (SNP) analysis of seven Xinjiang native horse breeds. W...
Chessari G, Reich P, Criscione A, Falker-Gieske C, Mastrangelo S, Tumino S, Bordonaro S, Marletta D, Tetens J.Single nucleotide polymorphism (SNP) arrays are commonly used for studying the genomic structure and diversity of livestock breeds, but whole-genome sequencing (WGS) provides higher-resolution genomic data. Genotype imputation has become a standard practice for increasing the genomic resolution of association studies. This work aimed to extend imputation to biodiversity analyses, comparing SNP array data before and after imputation. A 40 k SNP dataset of 281 horses from 12 breeds (DS) was imputed to sequence-level using a reference panel of 327 sequenced individuals, generating approximately 9...
Souza LL, Lima AS, Martins AS, Silva TA, Borsanelli AC, Dutra IS, Pupin RC, Gomes DC, Lemos RA.An outbreak of botulism occurred in March 2024 among horses at a Quarter Horse stud farm in Central-West Brazil. After ingesting baleage, 22 of 26 (85%) horses housed in stables and fed baleage became ill. The affected horses had dysphagia, muscular weakness, fasciculations, and progressive recumbency; 13 of 22 (59%) died within a few days. The diagnosis of type C botulism was established based on clinical and epidemiologic findings and confirmed by mouse bioassays, which indicated botulinum toxin type C in liver samples and intestinal contents. Furthermore, PCR testing identified toxigenic i...
Yang L, Shen Z, Song L, Lu Z, Zeng Y, Wang J, Ren W, Yao X, Meng J.Fat deposition is a key economic trait in livestock, yet distinct adipose depots often display marked functional heterogeneity. The molecular basis underlying this divergence in Yili horses, however, remains poorly understood. Therefore, we hypothesized that the heterogeneity in fatty acid composition between subcutaneous (SAT) and pericardial adipose tissues (PCAT) in Yili horses is associated with distinct transcriptional programs, which can be explored using an integrated multi-omics approach. Using targeted metabolomics, we found that PCAT contained significantly higher levels of total, sa...
