Chỉ tiêu huyết học của lợn Piétrain kháng stress nuôi tại Xí nghiệp Chăn nuôi Đồng Hiệp Hải Phòng

This study was carried out on 50 stress negative Piétrain pigs (Pietrain ReHal): 15 pigs at 2 months of age, 20 pig at 5.5 months of age, 5 boars and 10 sows raised in the livestock farm of Dong Hiep, Hai Phong in order to establish the hematological reference values and their variability according to 4 groups of pigs (2 months, 5.5 months old, boar and sow). Significant group differences were found in hematological parameters except red cells, hemoglobin, eosinophil, basophil, total protein and sugar. These values were within the normal ranges generally accepted as reference values for healthy pigs. Piétrain stress negatif pigs could gradually adapt to the animal production condition in Hai Phong, Vietnam.
