OBSERVATIONS REGARDING SOME ENVIRONMENT FACTORS ON HEMOLEUCOGRAMA IN LACTATION OVINES

M. Condrea

Abstract
A study was made on a lot of Merinos de Palas sheep, with the same age (second lactation) and the same milk production. Some hematologic marks were investigated during winter season (February) and summer season (June). The results show a decrease in the average values of the erythrocytes number (9.9x106/mm3), hemoglobin 10.9g/dl) and hematocrit (34.2%) during the winter season as compared to the summer season (10.7x106/mm3; 11.2g/dl; 36.8%). These variations do not exceed the physiologic limits of the species. In the leukocytes series there is an increase in the average values of the leukocytes number during wintre season (9.9x103/mm3) as compared to the warm season, but without pathologic significance and a slight increase of limphocytes (63.07%). We can conclude that there is a corelation among alimentation, environment temperature and the value of some hematologic marks.

Rezumat
S-au luat īn studiu un lot de oi din rasa Merinos de Palas, de aceeasi vārsta (lactatia a II-a) oi cu aceeasi productie de lapte.
S-au investigat īn sezonul de iarna (februarie) si sezonul de vara (iunie) unii indicatori hematologici. Rezultatele obtinute arata o scadere valorile medii ale numarului de eritrocite (9,9x106/mm3), ale hemoglobinei (10,9g/dl) si hematocritului (34,2%) īn sezonul de iarna comparativ cu cele ale lotului din sezonul de vara (10,7x106/mm3; 11,2g/dl; 36,8%). Aceste variatii nu depasesc limitele fiziologice ale speciei. Īn seria leucocitara se constata o crestere a valorilor medii ale numarului de leucocite iarna (9,9x103/mm3) comparativ cu sezonul cald, dar fara semnificatie patologica si o usoara crestere a limfocitelor (63,07%). Se poate aprecia ca exista o corelatie īntre alimentatie, temperatura mediului si valoarea unor indicatori hematologici.
