Changes in the plasma biochemistry of 12 stallions were studied over seven 24 h periods, Twelve healthy male horses of 4 different breeds (Thoroughbred [TB], Anglo-Arabo-Sardo [AAS], Avelignese [Av] and Maremmano [M]) were divided into 3 experimental groups and fed with an isoenergetic maintenance ration with different protein levels, The same amount of food was given daily at 0730 and 1930 h, After 20 days of pretrial, a series of 6 blood samples were collected daily from the jugular vein every 4 h for 7 days, The samples were analysed for packed cell volume (PCV), haemoglobin, plasma glucose, free fatty acids, cholesterol, total plasma protein, urea, creatinine, calcium, phosphorus and enzymatic activities: aspartate aminotransferase (AST), alanine aminotrasferase (BLT), creatine kinase (CK) and lactate dehydrogenase (LDH), The data were analysed following the armonic analysis (Fourier) in order to define the pattern of biorhythm, Many parameters showed a biorhythmical pattern, Protein levels of the diet failed to influence haematology, blood biochemistry and biorhythm, Thoroughbreds showed the highest values of PCV, haemoglobin and creatinine and the lowest total protein, phosphorus and enzymatic activities.

Abstract
Changes in the plasma biochemistry of 12 stallions were studied over seven 24 h periods, Twelve healthy male horses of 4 different breeds (Thoroughbred [TB], Anglo-Arabo-Sardo [AAS], Avelignese [Av] and Maremmano [M]) were divided into 3 experimental groups and fed with an isoenergetic maintenance ration with different protein levels, The same amount of food was given daily at 0730 and 1930 h, After 20 days of pretrial, a series of 6 blood samples were collected daily from the jugular vein every 4 h for 7 days, The samples were analysed for packed cell volume (PCV), haemoglobin, plasma glucose, free fatty acids, cholesterol, total plasma protein, urea, creatinine, calcium, phosphorus and enzymatic activities: aspartate aminotransferase (AST), alanine aminotrasferase (BLT), creatine kinase (CK) and lactate dehydrogenase (LDH), The data were analysed following the armonic analysis (Fourier) in order to define the pattern of biorhythm, Many parameters showed a biorhythmical pattern, Protein levels of the diet failed to influence haematology, blood biochemistry and biorhythm, Thoroughbreds showed the highest values of PCV, haemoglobin and creatinine and the lowest total protein, phosphorus and enzymatic activities.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
