Situation of helminthic infection in dairy cattle of household farms in Hoc Mon and Cu Chi districts, Ho Chi Minh City

Abstract

The objective of study aimed at evaluating situation of helminthic infection in the dairy cattle of household farms in Ho Chi Minh City. A total of 219 fecal samples from 219 dairy cattle belonging to Holstein Friesian hybrid breed of 10 household farms in Cu Chi and Hoc Mon districts, Ho Chi Minh
City were collected and examined by simple sedimentation and flotation techniques for identifying helminthic eggs. The studied results showed that the rate of cattle infected with roundworms and flukes was very high (71.7%). In which, the rate of cattle infected with roundworms was the highest (60.7%);
with liver and rumen flukes was 17.4% and 45.2%, respectively; the rate of cattle infected with two or three types of the above parasites was 42.9%. The rate of heifers infected with helminth was 54.1% compared to the cows with 1 parity and 2 parities (84.1%; P < 0.001) and the cows with ≥ 3 parities (78.0%; P = 0.002). The infection rate of the dewormed cattle (42.3%) was lower (P < 0.001) than that of the cattle without deworming (87.9%). The infection rate of cattle eating field grass was higher (P < 0.001) (78.1%) than the cattle eating grass from gardens (52.7%). The body condition scores of the infection cattle was lower than that of the healthy cattle (2.65 vs 2.80; P < 0.001).
