Zinc is an essential trace mineral that plays a critical role in numerous physiological processes in horses, including immune function, enzyme activity, and cellular repair. It is a vital component of various enzymes and proteins, contributing to antioxidant defenses and the maintenance of skin integrity. Adequate zinc levels are important for optimal growth, reproduction, and overall health in equines. Horses typically obtain zinc through their diet, with absorption occurring primarily in the small intestine. Deficiencies or imbalances can lead to clinical signs such as poor coat condition, delayed wound healing, and impaired immune response. This page compiles peer-reviewed research studies and scholarly articles that explore the dietary requirements, absorption mechanisms, and clinical implications of zinc in equine nutrition and health management.
JENNINGS FW, MULLIGAN W.THE chemical analyses reported in this paper arc the result of an investigation on the sera of thirty normal horses from a heavy draught horse stable in Glasgow. Determinations have been made of scrum proteins (albumin and total globulin), alkaline phosphatase, bilirubin, calcium, magnesium, inorganic phosphate and urea. Estimations of some of these constituents have already been carried out by a number of workers, but in the majority of cases the investigation has been confined to one or two constituents relevant to the problem being studied, and many of the data available are a by-product of...
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...
Hajimohammadi A, Ghane M, Ghari Tehrani M, Paravar B, Mirzaei A, Razavi S, Nikzad M.Sixty-one horses were enrolled in this study and divided into 3 different groups according to their severity of colic (heart rate, oral mucous membrane color, and abdominal distention): a strangulating colic (SC) group (n=21), non-strangulating colic (NC) group (n=20), and control group (n=20) consisting of randomly selected normal horses without signs of colic. The serum concentrations of haptoglobin, tumor necrosis factor-α (TNFα), nitric oxide (NO), malondialdehyde (MDA), zinc, iron, and copper were evaluated in all horses. The average concentration of TNFα in the SC group was higher tha...
Aragona F, Cicero N, Nava V, Piccione G, Giannetto C, Fazio F.Biological monitoring of trace element horses is a well-known tool for investigating potential bioaccumulation in urbanized and industrialized geographical areas. Some biomaterials such as hoof are considered as an important indicator of environmental pollution. Hooves can store trace elements for a long time compared to blood and this represents a scientific key to long-term monitoring of exposure to environmental pollutants. In the present study, samples of equine hoof and blood were taken from an experimental group of horses living in an industrialized area of Sicily (Italy) and from a cont...
Giers J, Bartel A, Kirsch K, Müller SF, Horstmann S, Gehlen H.After submaximal exercise, blood values of eventing horses show physiological reactions. This prospective longitudinal study investigated blood parameters in 20 elite eventing horses before and after two-four-star cross-country rides. Using a mixed model adjusting for plasma volume shift, we assessed exercise-dependent parameters and compared blood values with reference ranges for healthy horses at rest. Following exercise, cortisol, triiodothyronine (T3) and thyroxine (T4) showed short-term increases, and superoxide-dismutase showed a small short-term increase. Hepatic values showed short-ter...
Stahl LT, Müller A, Krohn J, Büttner K, Wehrend A.An adequate supply of trace elements is very important for equine neonates, as deficiencies can lead to health problems and even death. Unassigned: This study investigated serum concentrations of selenium (Se), copper (Cu), and zinc (Zn) in neonatal foals up to the 8th day of life. The influences of disease, age, and failure of passive transfer (FPT) on these concentrations were analyzed. Unassigned: Serum concentrations of Se, Cu, and Zn were determined from blood samples of 93 foals by means of inductively coupled plasma mass spectrometry. The foals were divided into 2 groups based on health...
