in various breeds of chickens in Thai Nguyen province

Nguyen Van Suu

SUMMARY

A study of the blood parasitism by Leucocytozoon in chickens by breed in the province of Thai

Nguyen indicated that:

By the clinical signs, the prevalence of the infection was found varying from 15.22 to 19.59%

depending on the chicken breed. Precisely, the prevalence in the Mia chicken flocks was 35.48% (11/31

flocks); in the Luong Phuong's one: 37.84% (14/37 flocks); in the Sasso: 40.91% (9/22 flocks) and in the

native chickens: 38.46% (15/39 flocks). By the hematological examination, the parasites were found in

both the sick and the healthy chickens. The positiveness was found in 84.05% of the clinically sick and

in 35.87% of the apparently healthy chickens. The intensity of the infection was found high in 52.55%

and very high in 30.66% of the sick birds; the intensity was qualified as lightly in 18.18% and very lightly

in 81.82% of the healthy chickens.
