Resumo
Com o objetivo de estudar as concentrações de zinco da sola do casco de bovinos com e sem lesões podais, suplementados ou não com levedura seca, foram selecionadas e examinadas 60 vacas, escolhidas aleatoriamente, de um rebanho de 150 animais. Formaram-se quatro grupos de 15 animais, sendo o primeiro com animais com lesões podais e suplementados com levedura, o segundo com animais com lesões podais e sem suplementação de levedura, o terceiro com animais sem lesões podais e suplementados com levedura e o quarto com animais sem lesões podais e sem a suplementação de levedura. As concentrações de zinco da sola do casco foram determinadas por espectrometria de absorção atômica com chama (AAS). A comparação estatística das concentrações de zinco nas amostras foram submetidos à análise de variância, seguida pelo teste de Tukey, para comparação de médias. As médias das concentrações de zinco da sola do casco dos animais dos quatro grupos, quando comparadas estatisticamente, apresentaram diferença estatística significativa, somente nos animais com lesões podais e suplementados com levedura.
With the goal of studying the hoof sole zinc concentrations of cow with and without foot lesions, suplemented or not with dried yeast from sugarcane; 60 cows were chosen from milking of 150 animals. Four groups of 15 animals were formed being the first one of animals with foot lesions and with supplemental yeast, the second one of animals with lesions and without supplemental yeast, the third group of animals without foot lesions and with supplemental yeast and the fourth one of animals without foot lesions and without supplemental yeast. Hoof sole zinc was determined by the Atomic Absortion Spectrophotometry (AAS). The results were statistically evaluated by analysis of variable, followed by Tukey s test to compare mean levels. The mean concentration of zinc in the hoof sole of the groups statistically, significant showed differences only in the animals with foot lesions and with yeast supplementation.
