Abstract

In animal production, it is of fundamental importance the rational use of good quality water. Water should be considered as an essential nutrient and when the quality used in animal consumption is doubtful, this can interfere with the performance parameters and the spread of diseases, causing serious economic losses. The objective of this research to diagnose the quality of water that is supplied to the watering water quality bovine in school-farm at IFRN-Ipanguaçu. Sampling and analyzes were carried out fortnightly in the water drinker of bovine (a total of six drinking fountains) during the months of June to September 2015. The parameters analyzed were: temperature, pH, conductivity, dissolved oxygen and total dissolved solids; using a multi-parameter explorer water quality. The data revealed that the parameters except total dissolved solids, met the limits acceptable by Resolution CONAMA 357/2005, with occasional drinkers presenting unacceptable results. However, it is also necessary to a proper water management (with constant renewal) and drinkers who are willing not only in readily accessible to animals, but they can also be in local or airy covered by tree canopy.
