Abstrak: The aim of this study was to investigate the effect of Haemonchus contortus infection to white blood cell profile of Javanese thin tail sheep. Twenty males Javanese thin tailed sheep were divided into five groups, namely infected group of 500 L3, 1000 L3, 2000 L3, 4000 L3 and uninfective group as control. The blood and fecal samples were collected from rectum before and three weeks after infection. The blood samples were collected using venoject® from Jugular vein. The fecal samples were collected directly from rectum. The blood samples were examined to determine total of white blood cell (leukocytes) and white blood cell differential, whereas fecal samples to determine egg per gram. The result showed that Haemonchus contortus infections cause an increased total of leukocyte but were not significantly different among of level infection doses (P>0.05). Number of eosinophils were significantly different among uninfected group (P<0.05), but were not significantly different in number of lymphocyte, monocyte, and neutrophil (P>0.05). There where positively correlated significantly between the amount of egg per gram (EPG) and profile of eosinophil (P<0.05), however were negatively correlated significantly between the amount of egg per gram (EPG) and neutrophil’s profile (P<0.05). There where no correlation significantly between the amount of egg per gram (EPG) and profile of white blood cell, lymphocyte, and monocyte (P>0.05).

Abstrak: The aim of this experiment was to study the degree of helminth infection caused by Haemonchus contortus based on the number of worm and egg per gram of faeces (EPG) on thin tail sheep. Faecal samples were collected from 20 sheeps infected by Haemonchus contortus with the doses of 500, 1000, 2000, 4000 infected larva and non infected group as control. Adult worms were collected from the experimental sheeps at the end of experiment. In eighth week after infection, the results showed the highest establishment occurred on the infected groups of 500, 1000,2000 and 4000 larvae with the percentage of 50.1%, 14.6%, 6.1% and 3.6%, repectively.. Linear regression analysis showed strong relationship between the number of EPG and the number of worms of Haemonchus contortus. Degree infection were categorized based on the number of worms showed a mild infection with 1-250 worms produced as many as 50- 4400 EPG, medium infection with 251-500 worms produced as many as 4400- 8800 EPG and heavy infection with >500 worms produced >8000 EPG.
