The study aimed to verify the effect of water salinity and environmental temperature on the physiological variables (respiratory rate, heart rate, rectal temperature, and surface temperature) and ingestive behavior (rumination, feeding, drinking, and idle) of creole goats. Thirty-six males with an average age of 5.0 ± 0.6 months and an average weight of 20.0 ± 2.3 kg were housed in metabolic cages. The experimental design was a 2 × 3 type crossover (two temperatures and three levels of salinity). The two temperatures were: T1 = 26 ± 0.6 °C (thermoneutral) and T2 = 32 ± 1.2 °C (stress) and three levels salinity (1.0, 6.0, and 12.0 dS m-1). Between the temperatures, the respiratory rate (RR) and surface temperature (ST) present a difference (P < 0,05), being higher in the high temperature. Between temperatures, respiratory rate and surface temperature show a difference (P < 0.05), being higher at high temperature, keeping heart rate and rectal temperature similar at both temperatures. Among the different salinity levels in the behavioral activities, the feeding and urination activity presented a significant difference (P < 0.05), increasing with the water's salinity level. Between temperatures, the rumination efficiency dray matter and neutral detergent fiber showed a significant difference (P < 0.05). With increasing air temperature, they decreased the rumination time-water salinity levels influence (P < 0.05) the feeding efficiency of dry matter. Therefore, water with up to 9.600 mg TDS L-1 can be used strategically in the desedentation of goats in semi-arid regions.
