Previous issue date: 2005-03-09 / Coordena??o de Aperfei?oamento de Pessoal de N?vel Superior / The vitamin A is essential to animals because of its participation in a great number of biological functions. The investigation of this vitamin s concentrations is important to serve as reference to normality parameters. This study had as aim to analyse the serics and hepatics concentrations of vitamin A in two groups of bovines and to compare the hepatics concentrations to the present requeriments of vitamin A for pregnant women. It was also appraised the consume habit of bovine liver by pregnant women through of the alimentary frequency quest. Two groups of bovine were studied and the first was formad by Nelore bovine breed and the second by bovine without defined breed (WDB). It was analysed 120 samples: 60 of liver and 60 of serum. The method used to dose retinol was High Performance Liquid Cromatography (HPLC). The average (+ sd) of retinol concentrations in Nelore breed bovine and WDB liver were 16947,8 + 6866,9 and 5213,1 + 2517,2 ?g of retinol/100g and at serum 39,6 + 17,9 e 28,6 + 9,4 ?g of retinol/dL, respectively. No statistically significant correlation was found between hepatic and the serum retinol. The bovines in this study had adequate vitamin A levels. Independently of animal breed, the daily ingestion of bovine liver is not advised for pregnant women who show adequate support of vitamin A. The consume of bovine liver by pregnant women consulted on school maternity hospital Janu?rio Cicco, UFRN, Natal RN, was considered high / A vitamina A ? essencial aos animais devido sua participa??o em uma s?rie de fun??es biol?gicas. A investiga??o das concentra??es desta vitamina ? importante para servir como refer?ncia para par?metros de normalidade. O objetivo do presente estudo foi analisar as concentra??es s?ricas e hep?ticas de vitamina A em dois grupos de bovinos e comparar as concentra??es hep?ticas com os atuais requerimentos desta vitamina para gestantes. Avaliou-se tamb?m o h?bito de consumo de f?gado bovino por mulheres gestantes atrav?s do question?rio de freq??ncia alimentar. Dois grupos de bovinos foram estudados sendo o primeiro formado por bovinos da ra?a Nelore e o segundo por bovinos sem ra?a definida (SRD). Analisou-se 120 amostras: 60 de f?gado e 60 de soro. O m?todo utilizado para dosar retinol foi a Cromatografia L?quida de Alta Efici?ncia (CLAE). As m?dias (+ dp) das concentra??es de retinol no f?gado dos bovinos da ra?a Nelore e SRD foram 16947,8 + 6866,9 e 5213,1 + 2517,2 ?g de retinol/100g e no soro 39,6 + 17,9 e 28,6 + 9,4 ?g de retinol/dL, respectivamente. N?o foi encontrada correla??o estatisticamente significativa entre o retinol hep?tico e o s?rico. Os bovinos do presente estudo se encontravam com aportes adequados de vitamina A. Independentemente da ra?a do animal, a ingest?o di?ria de f?gado bovino ? desaconselhada para mulheres gr?vidas que apresentam aportes adequados de vitamina A. O consumo de f?gado bovino por mulheres gestantes atendidas na Maternidade Escola Janu?rio Cicco, UFRN, Natal RN, foi considerado alto
