A Contribution to the acid –base balance in normal & diseases sheep

One huncircd and four Balady sheep of both sexes were used in the present investigation. The aniYlals were divided into four grou~s: Group I consisted of 42 clinically normalBalady sheep, Group 11 of 33 sheep showing respiratory mffi1i-festations, Group 111 of 18 sheep affected wt th tympany andGroup IV of 11 sheep showing diarrhea.~vo venous blood samples were taken from each animal.The first was heparinized blood for the estimation of pH, PC02, P02, HC03-, BE,-rC02, SBE, SBC, SAT, Hb and PCV. Thesecond blood samples was obtained wi thout anticoagulant aridused for serum separation for the measurement of Na+, K+ andCl-.:,rhe resul ts s nowec no significant differences between clinically normal male arid f eme I dry re.tion. Varying degrees of acidosis were noticed indiseased groups. The least changes in the acid-base para-
