BLOOD CONSTITUENT CHANGES IN FASTED PONIES. Baetz, A.L. and Pearson, J.E. Am. J. Vet. Res.,

Feed was withheld from four ponies for 9 days, resulting in an average body weight loss of 26.1 kg. Blood 

 samples were collected each morning during the fast, serum was prepared, and serum constituents were determined. 

 Values during lasting were compared with prefasting and refeeding values. During fasting, body temperature, plasma 

 glucose, calcium, chloride, total protein, albumin, a 2 -globulin, /3-globulin, 7-globulin, a-lipoprotein, glutamic 

 oxalacetic transaminase (GOT), glutamic pyruvic transaminase (GPT), ornithine carbamyl transferase (OCT), alkaline 

 phosphatase (ALP), and creatine phosphokinase (CPK) concentrations were maintained at or near prefasting values. 

 Cholesterol, phospholipid, free fatty acids (FFA), esterified fatty acids (EFA), triglycerides, pyruvate, lactate, 

 ^-lipoprotein, and o^ -globulin significantly increased in plasma, whereas urea nitrogen, magnesium, and phosphorus 

 decreased during the fasting period. All plasma constituent values returned to prefasting values by the sixth day of 

 refeeding.
