| Description | Due to its necessity and magnitude, water is essential for animal nutrition. This study aimed to evaluate the effects of increasing levels of water salinity on the quality of goat milk in the Brazilian semiarid region. Twenty-four multiparous Alpine goats, with an average live weight of 38.0 ± 4.0 kg and an average lactation period of 30 days, distributed entirely at random, were used. The experiment lasted 64 days including an initial period of 14 days of adaption to the diet. The experimental treatments consisted of water with different levels of total dissolved solids (TDS): 640, 3188, 5740, and 8326 mg $L^{−1}$, obtained using sodium chloride (NaCl). Increasing the levels of TDS in drinking water from 640 to 8326 mg $L^{−1}$ did not significantly (p > 0.05) affect the production and the physicochemical composition of the milk. There was a linear increase (p < 0.05) in the water consumption and acidity variables as a function of the total dissolved solid levels. The mineral composition of the milk was not altered with increasing levels of TDS in water from 640 to 8326 mg $L^{−1}$. There was no negative effect (p > 0.05) for any of the sensorial attributes analyzed in relation to the treatments. Therefore, as a general conclusion, based on the analyses carried out in this experiment, it was found that water with total dissolved solids, when supplied for short periods of up to 48 days, does not alter the production, physicochemical characteristics, or the organoleptic properties of goat’s milk. |
