Abstract
The experiment aimed to evaluate the salt tolerance threshold in sheep drinking with diluted seawater was carried out on 10 rams, divided into two phases: Phase 1 (control, C) all rams were given fresh water for 7 days from two identical buckets, and daily water intake was recorded from both buckets. In phase 2 (preference test, PT), each ram was supplied with fresh water for the first bucket and diluted seawater (DSW) for the second bucket or vice versa. The concentration of DSW for preference tests ranged from 0.5% to 2.0%. The results from the experiment showed that body weight and dry matter intake did not differ by DSW, whereas water intake was significantly higher during phase 2 (P<0.05). Rams consumed more DSW at 0.5% level and then decreased to prefer DSW from 1.0% concentration, began to avoid DSW with 1.5% concentration, and rejected at 2.0%. Rams consumed with DSW increased plasma sodium and chloride concentrations, whereas plasma potassium did not differ between phases 1 and 2. Plasma levels of urea, creatine, AST and ALT remained unchanged between phases. It was concluded that Phan Rang rams can tolerate DSW up to 1%.
Tóm tắt
Thí nghiệm nhằm đánh giá ngưỡng chịu mặn của cừu (Ovis aries) và được thực hiện trên 10 cừu đực, chia thành 2 giai đoạn. Giai đoạn 1 cho cừu uống nước ngọt trong 7 ngày từ hai máng uống giống nhau. Giai đoạn 2 trong 8 ngày cho cừu uống nước ngọt cho máng uống thứ nhất và nước biển pha loãng (DSW) cho máng uống thứ hai hoặc ngược lại, nồng độ DSW (diluted seawater) từ 0,5% đến 2,0%. Kết quả cho thấy khối lượng cơ thể và lượng chất khô ăn vào không khác nhau bởi DSW, trong khi lượng nước uống vào cao hơn ở giai đoạn 2 (P<0,05). Cừu uống nhiều DSW ở nồng độ 0,5% và sau đó giảm sự lựa chọn DSW ở nồng độ 1,0%, tránh lựa chọn DSW ở nồng độ 1,5% và từ chối uống ở nồng độ 2,0%. Cừu uống DSW tăng nồng độ natri và clorua huyết tương, trong khi đó kali huyết tương không khác nhau giữa giai đoạn 1 và 2. Nồng độ urê, creatine, AST và ALT huyết tương không thay đổi giữa hai giai đoạn. Kết quả thí nghiệm cho rằng cừu có thể chịu đựng được DSW lên tới 1%.
