[Effect of anemia on various reactions of the domestic swine due to physical exertion. 3. Changes in plasma glucose and lactic acid concentrations].

Six anaemic and six healthy pigs were exercised for ten minutes on a belt moving at 78 m/min. Initial blood glucose values in healthy pigs averaged 71.2 mg/100 ml, and they changed very little during and after exercise. Initial values were similar in anaemic pigs (70.7 mg/100 ml), but they increased continuously, during exercise, reaching a peak of 157.4 mg/100 ml one minute after the end of exercise. Blood lactic acid increased from 1152 to 2463 mmol/litre in healthy pigs during the first minute of exercise, and then fell gradually. In anaemic pigs it increased from 1652 to 8478 mmol/l during the ten minutes of exercise, and then fell gradually. Correlations between lactic acid and haemoglobin content, between rectal temperature and Hb, and between lactic acid and changes in rectal temperature were discussed.
