Um experimento foi realizado para avaliar os efeitos da forma de fornecimento de água sobre o desempenho e a qualidade de ovos de poedeiras comerciais. Utilizaram-se 100 poedeiras comerciais com 44 semanas de idade distribuídas em um delineamento inteiramente casualizado com dois tratamentos (tipos de bebedouros: taça e nipple), cada um com dez repetições de cinco aves. O experimento foi conduzido durante 63 dias, divididos em três períodos de 21 dias. As aves que utilizaram bebedouro tipo nipple apresentaram maior porcentagem de postura e melhor conversão alimentar. A qualidade dos ovos não foi influenciada pelo tipo de bebedouro utilizado. O uso de bebedouro tipo nipple possibilita o fornecimento de água com melhor qualidade microbiológica para as poedeiras e, conseqüentemente, favorece o desempenho das aves. An experiment was carried out to evaluate the effect of different forms of water supply for laying hens on performance and egg and water quality. Two types of drinking system were evaluated: cup and nipple. In each treatment 10 replicates had been used, composed for five hens. The experiment lasted 63 days, divided in three periods of 21 days. Data of performance and egg quality were submitted to variance analysis and, when the differences were significant, they were compared by F test. Data of microbiological quality were compared by qui-square test. Hens submitted to nipple drinking system showed greater egg production and better feed conversion. No treatment differences on egg quality were detected. However, in the evaluations of the water bacteriological quality it was evident that the nipple drinking system provides better water quality and performance of laying hens
