OBSERVATIONS REGARDING SOME ENVIRONMENT FACTORS ON HEMOLEUCOGRAMA IN LACTATION OVINES
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 (9.9x 106/mm3), hemoglobin 10.9g/dl) and hematocrit (3.,2%) during the winter season as compared to the summer season (1.7x106/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.
