Se han analizado, en 40 corderas, 41 primalas, 51 andoscas, 50 trasandoscas y 46 ovejas, en anestro, estro y gestación, los siguientes parámetros sanguíneos: calcemia, fosfatemia. magnesemia, sodemia y potasemia, así como la actividad de las fosfatasas ácida y alcalina, S.G.O.T., S.G.P.T. y la actividad de la a-amilasa. Se produce como dato más destacable el incremento de Ca y P durante la gestación.

The following sanguineous parameters were analysed in 40 ewe lambs aged up to 1 year, 41 aged between 1 and 2 years, 51 aged betwen 2 and 3 years, 50 aged between 3 and 4 years, and 46 ewes over 4 years old in anoestrus, oestrus and gestation: calcaemia, phosphataemia, magnesaemia, sodaemia and potasaemia, as well as the activity of the acid and alkaline phosphatases, S.G.O.T., S.G.P.T. and the activity of the a-amylase. The most remarkable finding is the increase of Ca and P levels during gestation.
