Resumo: | This work had the objective of evaluating the method of 32P uptake by the erythrocytes of young sheep, supplemented with phosphorus and kept at pasture of Andropogon gayanus, as a tool for phosphorus deficiency diagnosis. Twenty lambs, initially weighing 13.88±2.51 kg, were divided in two treatments of ten animals each. In one of them, animals were supplemented with 3 g of phosphorus per animal per day and, in the other, animals did not receive supplementation of phosphorus. Weighing, and blood and faeces collection were carried out in the 8th, 29th, 43rd, 57th e 71st days of the experiment, to evaluate the incorporation of 32P by the erythrocytes, to determine calcium, glucose and phosphorus concentrations in the serum and percentage of P in the faeces. Significant difference for the concentration of Ca was found in the 57th day. For the glucose concentration, the percentage of phosphorus in faeces, and the weight, significant differences between the treatments were not observed. From the 29th to the 71st day, the concentration of phosphorus in the serum was higher, and the incorporation of 32P was lower in the group of animals supplemented with phosphorus. The analysis of 32P incorporation by the erythrocytes is an additional tool to evaluate the status of P, with identification of the subclinic deficiency in lambs. |

Vinte ovinos, com peso vivo inicial de 13,88±2,51 kg, foram divididos em dois tratamentos de dez animais cada; num dos tratamentos, os animais foram suplementados com 3 g de P por animal por dia e, no outro, os animais não receberam suplementação de P. Foram realizadas cinco pesagens dos animais, coletas de sangue e fezes nos 8o, 29o, 43o, 57o e 71o dias do experimento, para avaliar a incorporação de 32P pelos eritrócitos, determinar as concentrações de Ca, glicose e P no soro e a porcentagem de P nas fezes. Foi encontrada diferença significativa na concentração de Ca no 57o dia. Na concentração de glicose, porcentagem de P nas fezes e peso vivo não foram observadas diferenças significativas entre os tratamentos. A partir da segunda coleta, a concentração de P no soro foi mais elevada e a incorporação de 32P foi menor no grupo de animais suplementados com P. A incorporação de 32P pelos eritrócitos é uma técnica adicional para avaliar o status de P e identificar sua deficiência subclínica em ovinos jovens.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraAntunes, Dalton AraujoLouvandini, HelderFilho, José Cleto da SilvaMcManus, Concepta MargaretDallago, Bruno SteffanoMachado, Bruno de OliveiraMendonça, Dharana GuedesCorrea, Patrícia Spoto2006-02-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/7142Pesquisa Agropecuaria Brasileira; v.41, n.2, fev. 2006; 339-345Pesquisa Agropecuária Brasileira; v.41, n.2, fev. 2006; 339-3451678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/7142/4187info:eu-repo/semantics/openAccess2014-09-26T17:37:04Zoai:ojs.seer.sct.embrapa.br:article/7142Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-09-26T17:37:04Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
