The influence of age and the reproductive status to the blood indicators of the ewes

The influence of age and the reproductive status has been researched in the blood serum of 75 Merinolandschaf ewes. We have detected statistically very high concentrations of Ca in the blood serum of pregnant and non- pregnant ewes comparing to those in lactation, while the opposite way has been noticed for the concentrations of P-inorganic and Na. Statistically much higher concentrations of K have been found in the lactating and non- pregnant ewes comparing to the pregnant ones. Statistically much higher concentrations of albumin and cholesterol have been detected in the blood of pregnant ewes comparing to the non-pregnant ones, while the opposite way has been noticed for the concentrations of total proteins. GGT activity was statistically much higher in the blood of ewes in lactation comparing to the non-pregnant ones and the CK and ALT activity in the pregnant ones comparing to those in lactation. The ewes up to one year old had statistically very significant high concentrations of P-inorganic, Na, Fe, glucose, AP, GGT, CK activities and in the older ewes the concentrations of cholesterol and total proteins. Due to that, it is necessary to, before the metabolic profile specification of ewes, take into consideration age and the reproductive status of the animals. For the age there have to be taken the concentrations of P- inorganic, Na, Fe, glucose, cholesterol and total proteins as well as AP, GGT, CK activities and for the reproductive status the concentrations of Ca, P-inorganic, Na, albumin, total proteins as well as the ALT, CK, GGT activities. These researches give basis for the regular therapy application and carrying out the prevention of the metabolic disturbances of ewes in the aim of reducing economy losses.
