The hoof needs to have anadequate quality to be able to carry out these functions and that requires a good nutrition based on proteins, vitamins and minerals.Minerals constitute 4% of body weight and they are conformed by macrominerals (calcium, phosphorus, sodium, chloride,potassium, magnesium and sulfur) and microminerals (selenium, iodine, copper and zinc). Zinc participates in hoof formationwhile inducing keratin production. Its diet defi ciency causes problems to the corneous tissue such as: thin and friable hooves, andfi ssures on the wall. Zn++ must be ingested in chelated form, as zinc methionine, to be adequately absorbed. The diet of sevenhorses was supplemented with 5.4 g/day/horse of zinc methionine for a period of six months. Samples were obtained from thewall level and transverse cuts were done; before and after the treatment, its morphology and contents of minerals (Mg++, Cl, S,Ca++, Na++, K+, P, Si, Fe++, Cu++,Zn++) were analyzed in the environmental scanning electron microscope equipped with an X raydisperser. It was observed that the morphology presented a better constitution and compactness of the tubular and intratubularhorns in the medium stratum, as well as a substantial increment of zinc (32.9%) and sulfur (68.4%), which suggests an increase inkeratin and better structure of the hoof 2008 artículo científico 0301-5092 https://www.redalyc.org/articulo.oa?id=42339302 en http://www.redalyc.org/revista.oa?id=423 Veterinaria México application/pdf Universidad Nacional Autónoma de México Veterinaria México (México) Num.3 Vol.39 |
