Effect of Coriander sativum, piper betel (betel leaf) and Azadirachta indica (neem) on haematological parameters against cestode parasites of Capra hircus

The aim of the research was to obtain the effect of medicinal plants on the control of experimental multiple cestodes infection as an antihelminthic of Gastro intestinal tract in Capra hircus, and their effect on body weight gain and haematological parameter changes due to this parasitic infection. Helminths are the important cause of reducing the body weight and producing the diseases. The experiment was conducted for a period of 28days to study the effect of Coriander sativum.( 100mg/kg bwt.), Piper betel (100mg/kg bwt.), and Azadirachta indica (100mg/kg bwt.), against the gastrointestinal cestodes in goat. The effect of coriander, betel leaf and neem on some haematological parameters (TEC, Hb, PCV, and TLC) and clinical parameters (body weight) were also observed. 24 goats which were naturally parasitized were divided randomly into group of four and each group consisting of six (6) goats. Goats of Group A were treated orally with the leaves of coriander. Group B was treated orally with the leaves of betel leaf. Group C was treated orally with the leaves of neem and Group D was kept as infected control. Faecal samples, body weight, haematological parameters were examined before treatment and on 3rd, 10th, 17th, and 28th day. After treatment with coriander and neem leaves the total erythrocyte count (TEC), haemoglobin (Hb), content and packed cell volume (PCV) were gradually increased significantly (P < 0.01 and P < 0.05) and conversely the total leukocyte count (TLC) were decreased significantly (P < 0.01 and P < 0.05). On the other hand TEC, Hb, PCV, were gradually increased on 3rd day and 10th day in betel leaf treatment but decreased on 17th and 28th day. Conversely the TLC were decreased on day 3rd and day 10th in betel leaf treatment but increased significantly on 17th and 28th day. The body weight was also increased in Coriander, Neem, and Betel leaf treated goats on the other hand body weight was significantly decreased in untreated control group. The present study reveals that leaves of Coriander and Neem were moderately effective and Betel leaf was less effective against the gastrointestinal cestodes in goats.
