[Annual dynamics of acidobasic indices in the sheep blood].

Altogether 218 sheep were followed for a year and the values of their acidobasic indices were examined, the follow-up comprises all seasons of the year, gravidity period, time of nursing and milk production. The actual pH value in the sheep blood varied from 7.30 to 7.48, with 7.40 average. The average value of partial CO2 pressure amounted to 37.26 torr the individual values varying between 30.0 and 47.5 torr. Baz excess varies from +5.0 to -6.3 mval/1 blood with year average of 1.11 mval/1 blood. Buffer baz was 43.0 mval/1 on the average, with variations from 34.2 to 48.9 mval/1 blood. Standard bicarbonate showed a relatively broad range of values from 19.0 to 28.0 mval/1 plasma, with 22.85 mval/1 average. Actual bicarbonate manifested similar variation dynamics as SB. Annual average was 22.92 mval/1 plasma, with variations from 19.0 to 28.2 mval/1. Total plasmatic CO2 had balanced average monthly values, with year average of 23.84 mval/1. Generally it can be concluded that after the sheep being out to grass the acidobasic blood indices became regulated.
