Blood gas tensions, acid-base measurements and electrolytes were determined in 10 healthy sheep and 10 healthy Goats. These values for sheep were blood pH 7.377+0.01, carbon dioxide tension Pco) 45.08 + 1.84 mmHg; oxygen tension (Po ) 34.07 + 2.61 mmHg; bicarbona te (Hco ) 25.71 + 2.01 mmol/L; total carbon dioxide (Tco) 25.84
2.07 mmol/L and Base Excess (B.E.) + 1.02 + 0.54 mmol/L. While the values for Goats were pH 7.383 + 0.03; Pco (40.53 + 6.2 mmHg); Po (41.63 + 4.04 mmHg); Hco (24.37 + 1.89 mmol/L; Tco (25.73 + 2.07 mmol/L.) and B.E. (+ 0.5 + 0.38 mmol/L). Serum Sodium, potass ium and chloride in sheep were 127.6 + 3.9 mmol/L. 4.12 + 0.79 mmol/L and 110.60 + 3.02 respectively. In Goats the values were Na (125.40 + 4.59 mmol/L); K (3.02 + 0.19 mmol/L) and chloride (108.6 + 4.4 mmol/L).
