Background and Aim: The high salinity of drinking water has been a significant problem of the Mekong Rivers Delta. Animals drinking high salinity water altered feed and water intake (WI), urinary electrolytes excretion, and productivity. This study aimed to evaluate the effects of high salinity in drinking water on drinking and eating behaviors and kidney function in crossbred goats.

Materials and Methods: The experiment was completely randomized with two treatments: freshwater (0%, seawater [SW0]) and water high in salinity (1.5%, SW1.5) from diluted SW, with five replicates (five animals per treatment). This experiment lasted 3 weeks: the 1st week for the pre-treatment period and the 2nd-3rd weeks for the post-treatment. Dry matter intake (DMI) and WI were recorded every day, while urine volume (UV) was determined from day 8 to day 21. Blood and urinary samples were collected on days 6, 14, and 21 of the study for electrolytes and creatinine analysis.

Results: The results demonstrated that both DMI and WI were affected by SW1.5 (p0.05), the weight gain observed in the SW1.5 group tended to decrease (p=0.056) at the 2nd week. The concentration of electrolytes in blood did not differ between the groups (p>0.05). In contrast, the concentration and excretion of Na+ and Cl- in urine increased in SW1.5 goats at D14 (p0.05).

Conclusion: The study concluded that crossbred male goats can tolerate 1.5% saline water from diluted SW for 2 weeks. The high salinity in water influences drinking and eating behavior in growing goats. However, the adaptive mechanism by increasing urine output and reducing the reabsorption of Na+ and Cl- in the kidney is the key function and works faster than behavioral responses. The kidney apparently drives drinking behavior during high salinity water consumption.
