Minerals are inorganic elements that are essential for various physiological functions in horses. They are involved in numerous biological processes, including bone formation, nerve function, and enzyme activity. Key minerals required by horses include calcium, phosphorus, magnesium, potassium, sodium, and trace elements such as zinc, copper, and selenium. The balance and bioavailability of these minerals are important for maintaining optimal health and performance in horses. This page compiles peer-reviewed research studies and scholarly articles that explore the roles, dietary requirements, and effects of mineral imbalances on equine health and performance.
The type of diet that a horse consumes is one of the most important factors determining the mineral profile and tensile strength of its hooves, so the quality and nutritional value of the supplied feed are fundamental to achieving satisfactory hoof quality. The objective of this study was to compare the differences in the mineral concentrations of sodium (Na), potassium (K), magnesium (Mg), zinc (Zn), and Iron (Fe) between two diets, namely silage and a commercial concentrate, using atomic absorption spectrometry and to determine which led to higher increases in the hoof tensile strength of ho...
Korim F, Revajová V, Koľvek F, Bujňák L, Hreus S, Všianský D.The parotid duct has been reported to be the most common site of sialoliths in horses. In this case report, we described the first confirmed case of the equine sialolithiasis in Slovakia. The work was aimed to describe the transcutaneous approach to removing the sialolith, which manifested as a hard painless mass in the area of the maxillary cheek teeth, in a 14-year-old Slovakian warmblood mare. Pathological-anatomical and histological examination after extirpation confirmed the presence of parotid duct ectasia resulting from calculus. The mineral composition of the sialolith was determined w...
Correa-Piña BA, Castillo-Paz AM, Davila U, Rodriguez-Garcia ME.The aim of this work is to investigate the changes in the physicochemical properties of hydroxyapatite (HAp) extracted from horse humerus bones of different ages (1, 3, 6, and 8 years) subjected to low temperature calcination (600°C). Thermal analysis revealed significant mass loss due to water, collagen, organic compounds, carbonates, and age-related magnesium out-diffusion. Higher fat content in older bones contributed to increased mass loss. Phosphorus content remained constant across age groups, while calcium and sodium showed age-related fluctuations. Magnesium levels decreased with ag...
Respirable mineral particles can induce lower airway inflammation, but the role they play in asthma of horses is unknown. Objective: Respirable mineral particles, particularly respirable silica, are an overlooked determinant of chronic lung inflammation (asthma) in horses. Methods: Twenty-three horses from an equine hospital population: 11 moderately affected (MEA), 7 severely asthmatic (SEA), and 5 control horses free from respiratory clinical signs. Methods: Prospective observational study. The quantity and quality of mineral particles found in bronchoalveolar lavage fluid (BALF) were charac...
Busch F, Leal ODA, Siebers N, Brüggemann N.During composting of organic waste, nitrogen is lost through gaseous forms and ion leaching. Biochar has been shown to capture mineral nitrogen (N: NH and NO ) from compost, which we hypothesize reduces NO formation. However, associating N captured by biochar with the dynamics of NO and other greenhouse gas (GHG) emissions during composting remains unstudied and was the aim of this work. We composted (outdoor for 148 days) together kitchen scraps (43.3% dw, where dw is dry weight), horse manure (40.9% dw), and wheat (Triticum aestivum L) straw (15.8% dw) without (Control) or with biochar (Bc,...
Wu J, Na H, Bai F, Li S, Gao H, Sha R.Horse bone is rich in collagen, with a composition similar to that of human collagen. Collagen peptides supply nutrients needed for human growth that act as antioxidants, lower blood pressure. This study explored the extraction of collagen and the preparation of collagen short peptides from Mongolian horse bones. Bones were collected from horses of varying ages, and the collagen content along with calcium salt distribution were observed through staining and imaging analyses. Next, the bones were processed into a powder and then subjected to ultra-high-pressure processing for degreasing. The de...
LeCompte Lazić RA, Nielsen BD, Robison CI, Schott HC, Herdt TH, Larson CK.The 2007 Horse NRC reduced cobalt (Co) requirements from 0.1 ppm to 0.05 ppm in dietary dry matter, though preliminary research suggested increasing dietary-Co enhanced fiber digestion in horses. This study aimed to evaluate fiber digestion with varying dietary Co amounts, as well as to compare serum Co concentrations with dietary Co content. Four geldings (mean body weight [BW] 503 ± 37 kg) were studied in a 4 × 4 Latin square design consisting of four 5-week periods, each comprising a 2-week washout phase followed by a 3-week treatment phase. Supplementing 0.0, 5.6, 16.8, or 28.0 mg of Co ...
Halo M, Kirchner R, Tirpák F, Slanina T, Tokárová K, Kováčik A, Miškeje M, Greń A, Formicki G, Halo M, Madeddu R, Massányi P.The abundance of chemical elements in the blood of horses can indicate the physiological balance, health of animal as well as can be taken as an indicator of environmental pollution. The aim of this work was to analyse haematological, biochemical parameters, TOS, FRAP, SOD, Gpx, TAS and their correlations with concentrations of essential and risk elements in blood of horses stabled in two different locations: The National Stud Farm Topoľčianky (n = 11; 11 stallions, consisting of the breeds 6 Lipizzan, 3 Slovak warmblood, 2 Holsteiner) and Experimental Centre at Institute of Animal Husba...
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...
Fernández-Villa C, Miranda M, Rigueira L, Martinez L, Villanueva B, Freire S, López-Alonso M.Serum mineral concentrations are key indicators of nutritional status, metabolic function and health in horses; however, contemporary reference intervals (RI) derived from large, well-characterised populations remain scarce. Objective: To establish serum RI for macro- and microminerals in clinically healthy horses in Northwestern Spain and to evaluate the influence of sex, age, breed and diet on mineral status. Methods: Blood samples were collected from clinically healthy horses (n = 211), and serum concentrations of essential macrominerals (calcium [Ca]; phosphorous [P]; magnesium [Mg]; sodiu...
Stanek M, Różański SŁ, Sztuka H, Komosa M.Research on the characteristics of the mineral profile of hooves can help prevent overgrowth or micro-cracks. Knowledge about the interaction of these elements shows how imbalances can lead to hoof pathology or suboptimal hoof quality. Sulphur plays a key role in keratin synthesis, contributing to hoof elasticity and strength. Iron is involved in oxygen transport to the hoof matrix cells, supporting proper metabolism and tissue regeneration. Zinc promotes keratinocyte differentiation and accelerates healing of micro-injuries within the horn structure. Copper is essential for the formation of d...
Octaviano JI, Alonso MA, Boakari YL, Gomes V, Mori CS, Fleury PDC, Fernandes CB.Monitoring equine parturition effectively is essential for preemptive intervention in periparturient issues and ensuring the overall well-being of both mares and foals. However, its implementation in breeding farms is challenging due to variable gestational lengths and nocturnal births. Predictive techniques have the potential to streamline the monitoring process, reduce labor intensity, and minimize costs. Research on foaling prediction in mares carrying mule or equine clone fetuses is scarce. Therefore, this study aimed to comparatively analyze foaling prediction parameters in mares pregnant...
Marcelino I, Monti G, Cornelissen P, Bassingthwaighte E, Het Lam J, van der Merwe D, van der Poel WHM.Trace minerals are essential for animal health but can also, together with heavy metals, have a negative impact, making their monitoring crucial to assess animal health. These elements were examined through a long-term post-mortem monitoring system based on routine liver sampling for Heck cattle, Konik horses and red deer in place at the Oostvaardersplassen nature reserve in the Netherlands, using data from this system to determine reference intervals and investigate trends in liver trace element concentrations. Throughout the monitoring programme, inductively coupled plasma mass spectrometry ...
