Clinical symptoms and blood physiological parameters of porcine epidemic diarrhea (PED) infection pigs raising in Thanh Hoa province

Abstract

The study were conducted to determine the clinical manifestations and some blood physiological characteristics of the Porcine Epidemic Diarrhea (PED) infection pigs in comparison with the healthy pigs raising in Thanh Hoa province. The studied results showed that the typical clinic symptoms included yellow liquid diarrhea, moodiness, tiredness, thinning (100%); laying on abdomen of the mother or overlap together (82.50%); anorexia (42.50%); vomiting (40.00%). The PED infection pigs had a number of erythrocytes and hematocrit (7.76x106/μL and 43.84%) higher than that of the healthy pigs (6.51 x106/μL and 37.30%). The average hemoglobin content and concentration in the PED infection pigs was higher than that of the healthy pigs (p<0.05). The number of leukocytes in the PED infection pigs (20.43 x103/μL) was higher than that of the healthy pigs (14.70 x103/μL), however, the number of the big mononuclear leukocytes and the lymphocytes were lower than that of the healthy pigs (p<0.05).
