Pasture and horses involve the study and management of grazing environments and their impact on equine health, nutrition, and behavior. Pastures serve as a primary source of forage, providing essential nutrients and contributing to the overall well-being of horses. Factors such as pasture composition, quality, and management practices influence the nutritional intake and health of grazing horses. Research in this area often focuses on optimizing pasture conditions to support equine dietary needs, prevent overgrazing, and manage pasture-related health issues such as laminitis. This page compiles peer-reviewed research studies and scholarly articles that explore the relationship between pasture management and equine health, including topics on forage quality, grazing behavior, and pasture maintenance strategies.
Tanhuanpää E, Knudsen O.The milk fat from 20 mares on pasture and 9 stable-fed mares was analysed. It is richer in C18:3 than the milk of other domestic species. This was especially marked when the mares were on pasture and were not given any grain. Further, mare’s milk fat is rich in fatty acids containing less than 14 carbon atoms in their chains. Das Milchfett von 20 Stuten auf der Weide und von 9 stallgefütterten Stuten wurde analysiert. Es enthält mehr C18:3 als das Milchfett anderer Haustiere. Dieses war speziell ausgeprägt für Stuten die auf der Weide gingen und kein Getreide bekamen. Das Milchfett der S...

Methods: Online survey. Methods: Descriptive and inferential (Kruskal-Wallis test) analysis of 246 surveys from owners of U.S.-resident senior horses used for competition. Confidence intervals were calculated for prevalence estimates of clinical signs and medical conditions. Results: Competing senior horses we...
Bishop RC, Kemper AM, Clark LV, Wilkins PA, McCoy AM.Equine gastrointestinal microbial communities vary across the gastrointestinal tract and in response to diet or disease. Understanding the composition and stability of gastric fluid microbiota in healthy horses is a prerequisite to understanding changes associated with the development of disease. The objective of this study was to describe microbial communities in the gastric fluid and feces of healthy horses longitudinally. Horses were maintained on pasture (6 weeks), stabled (5 weeks), then returned to pasture. A consistent forage diet was provided throughout. Native gastric fluid and feces ...
Kaufman KL, Suagee-Bedore JK, Johnson SE, Ely KM, Ghajar SJ, McIntosh BM.Forage is essential for equine health and performance, but intake of elevated pasture nonstructural carbohydrates (NSC) may exacerbate metabolic disorders. This study aimed to investigate the influence of laminitis history on metabolic and morphometric responses in grazing horses. Twelve non-pregnant mares (15 ± 3.4 yrs) were selected based on previous diagnosis of laminitis (PRELAM; n=6) or not (NOLAM; n=6). Horses were maintained on 8.5-ha pasture. Weekly pasture samples were clipped at random for nutrient analysis. Monthly blood samples were collected and analyzed for glucose and insulin c...
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...
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...
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...
Ryu SH, An SJ, Forbes E, Kim BS, Choe S.Equine strongyle infections are prevalent among grazing horses worldwide, yet research on anthelmintic efficacy and parasite management strategies in South Korea remains limited. This study investigated the infection dynamics and parasite burden in horses managed under different systems (pasture vs. stable) over a one-year period in Jeju, South Korea, assessing the impact of management practices on parasite burden and the effectiveness of current deworming regimens. Thirty-two horses were administered ivermectin/praziquantel in June 2022 and assigned to either pasture (n = 16) or stable (n...

Giovannetti-Singh G.In 1644, the Manchus, a Tungusic population from northeast Asia, conquered Ming China, establishing the Qing Empire. Four years later, Crimean Tartar horsemen joined a major uprising against the Polish-Lithuanian Commonwealth, gravely destabilizing one of Europe's largest states. These near-simultaneous incursions by ostensibly nomadic, horse-riding 'Tartars' into firearm-defended sedentary states generated extensive historiographical reflection on the role of nomads and their warhorse-centred armies in shaping human history. This article explores how the Jesuit Martino Martini drew on these T...
Barnabé MA, Elliott J, Harris PA, Menzies-Gow NJ.Insulin dysregulation (ID) and hypoadiponectinaemia (total [adiponectin] <7.9 μg/mL) are risk factors for laminitis. They are sometimes, but not always, associated with obesity. Objective: To investigate the effects of pasture consumption and obesity on ID and circulating total [adiponectin] in ponies. Methods: Longitudinal. Methods: Seven native-breed ponies with normal basal and post-oral sugar test (OST) [insulin] and body condition score (BCS) 4.3-5.5/9 were allowed to graze until they reached BCS 7/9. Ponies were then maintained at BCS 7/9 until completion of the study (week 22). Morph...
Bouquet A, Nicol C, Díez-León M.The natural behaviour of wood-chewing (WC) in horses may, under certain conditions, become excessive or it may precede crib-biting . However, the potential causes of WC, including frustrated foraging motivation) or developmental exploratory or teething behavior are poorly understood. We studied WC in 31 mares and their foals, examining associations with browsing access, stocking density, foal sex and performance of other non-nutritive oral behaviors. Behaviors (counts/hour) were recorded by all-occurrences sampling during focal, continuous observations of grazing,resting and suckling for 20 ...
Toishimanov M, Zhanten O, Kanat R, Beishova I, Ulyanov V, Assanbayev T, Sharapatov T, Daurov D, Daurova A, Sapakhova Z, Nametov A, Shamekova M.This study aimed to evaluate the chemical composition of milk from Kazakh mares kept under free-grazing conditions on natural pasture without supplementary feeding. Fifty Kazakh mares were aged 3 to 13 years, kept in herds, and categorized by age, number of foalings, and lactation stage for statistical analysis. Milk samples were collected, chilled, and analyzed on the same day using a Milkoscan FT2. The composition of fat, protein, lactose, total solids, casein, and other components was examined. Statistical analyses, including ANOVA, PCA, CDA, and Pearson correlation analysis, were performed...
