Resumo: | ABSTRACT The consumption of saline water in semiarid regions is a recurrent situation that can affect the ingestive behavior of small ruminants. This study evaluated the ingestive behavior of Santa Inês sheep maintained in a climatic chamber under two air temperatures -25 °C within the thermal comfort zone (TCZ) and 32 °C above the TCZ - and consuming water with three levels of salinity - 2.0, 4.0, and 8.0 dS m-1. The experimental design was completely randomized in 2 × 3 factorial schemes, comprising two air temperatures and drinking water with three levels of salinity, in six replicates (animals). Regardless of air temperature, the consumption of saline water did not affect feed and water intake by the sheep; however, there was a decrease in feed intake and an increase in water intake as air temperature increased. Feed and water intake; feeding, rumination, and idle times; defecation frequency; and fecal production were not affected (P &gt; 0.05) by the water salinity levels, whereas reduction in feed intake, feeding time, and rumination time and an increase in water intake and idle time were observed as air temperature increased. In summary, increasing air temperature negatively affected the ingestive behavior of the animals; however, water with salinity up to 8.0 dS m-1 did not affect their ingestive behavior and hence could be used for drinking.
