The experiment was conducted to evaluate the ingestive behavior of feedlot lambs fed with an exclusive diet of concentrate with different percentages of protein (14, 16, 18, and 20%). A total of twenty four Santa Inês crossbred lambs, not castrated, with approximately 180 days of age, average live weight of 25kg, confined, in a completely randomized design, with four treatments and six repetitions. The time spent on feeding decreased linearly in 0.20 hours/day for each 1% increasing in protein percentage in the diet, the idleness increased linearly in 0.25 hours/day, and the total chewing decreased linearly in 0.25 hours/day. The increase in the protein percentage in the diet increased the feed efficiency linearly (kg DM and NDF/hour) in 0.038 and 0.005kg/hour, respectively, for DM and NDF fractions. However, the intake of dry matter (DM) and neutral detergent fiber (NDF), the rumination efficiency (kg DM and NDF/hour), as well as the period (nº /day) and the time (min) spent on feeding, ruminating and idling were not influenced by different protein percentages in the diet.

We conducted a study of the quality of water distributed by Artesian Well in relation to water supply served by the public for purposes of human consumption of UNESP Campus Guaratinguetá. Two sections of the network were randomly chosen and monitored for 105 days: the stretch of the pipeline started off the Water Treatment Station of the Autonomous Service of Water, Sewage and waste in the Municipality of Guaratinguetá and ended in a point consumption of the Child Family Center, while the section B began at the output of an artesian well and finished in a point of consumption of the Department of Civil Engineering. It is the deterioration of water quality in parts A and B, through comparative analysis of Bicarbonates, Total Hardness, Total Iron, free residual chlorine, pH, Total Residual, Turbidity, Conductivity, Color, Fecal Coliforms and Total Coliforms. Among the observations that can be highlighted: the Total Hardness was found in highest concentration in the extract; for Total Iron significant variations were obtained for both parts, and reduction of this parameter in two points of consumption analyzed, not the expected increase concentration, because the contact of water along the pipe, the CRL showed significant depletion to section A, which can be related to impurities in the water, the presence of biofilm on the walls of pipes, or because this is the stretch of greater extent to be covered by water for pH, this indicated that the water is alkaline and slightly acidic stretch in section B; Turbidity was found for the higher concentration to the passage, and a considerable reduction of this parameter at point consumption due to deposition of particulate matter along the stretch, the conductivity also showed a higher concentration in the extract, as well as an increase in this parameter at the point of consumption.
