Vitamin D in horses is a fat-soluble vitamin that plays a role in various physiological processes, including calcium and phosphorus metabolism. Horses primarily obtain Vitamin D through exposure to sunlight, which facilitates its synthesis in the skin, and through dietary sources. Adequate levels of Vitamin D are important for maintaining bone health and supporting metabolic functions. Research on this topic explores the synthesis, dietary sources, and metabolism of Vitamin D in equine species, as well as its impact on bone integrity and overall health. The page compiles peer-reviewed research studies and scholarly articles that investigate the factors influencing Vitamin D levels, its physiological roles, and its implications for equine health management.
Bukhari SSUH, Urooj S.In winter anestrous, prolonged melatonin secretion inhibits gonadotropin-releasing hormone (GnRH). However, synthetic GnRH analogues such as buserelin can stimulate follicular development. We aimed to investigate clinical relationship between retinol, cholecalciferol, and buserelin for inducing estrous in anestrous mares (Equus caballus). We used a total of twenty-one anestrous mares, randomly divided into three groups of seven animals. Group A received retinol, cholecalciferol, and buserelin; group B received buserelin; and group C was control. Groups A, B, and C had 71.42% (n = 5; 95% CI...
Tretow M, Hain AM, Bienert-Zeit A.The dental syndrome EOTRH is a painful, progressive dental disease with an unknown aetiology. The often painful nature of EOTRH emphasises the need for a better knowledge of the underlying pathogenic mechanism and risk factors. A comparative analysis of haematological, biochemical and endocrine values in EOTRH-affected and non-affected horses has not been described. Objective: To compare haematological, biochemical, and endocrine parameters in EOTRH-affected and non-affected horses to detect risk factors for horses developing EOTRH. Methods: Cross sectional. Methods: Blood samples of 154 Icela...
Berghaus LJ, Venner M, Helbig H, Hildebrandt D, Hart K.Rhodococcus equi causes pneumonia in young foals, but disease susceptibility and severity vary. Cortisol and vitamin D modulate immune responses and cytokine production during bacterial infection, and altered concentrations are associated with sepsis in neonatal foals. We hypothesised an age and disease effect on circulating steroid hormone concentrations in foals, and that differences in cytokines and steroid hormone concentrations would predict disease severity in pneumonic foals. Objective: To investigate circulating concentrations of various cytokines, cortisol and vitamin D as predictors ...
