Abstract
The study was carried out to establish standard echocardiographic values and indices for adult Malabari goats and to study echocardiographic changes in Malabari goats with haemoparasitic diseases. Twelve healthy non-pregnant adult Malabari goats from Goat and Sheep Farm, KVASU, Mannuthy aged one to two years and body weight ranging from 20-25 Kg were utilized to establish standard echocardiographic indices for Malabari goat. Twelve female Malabari goats presented to the University Veterinary Hospitals at Mannuthy and Kokkala which were positive for blood parasites constituted the diseased group. The affected animals were of similar body weight and age group as the control animals. Echocardiographic study included B and M-mode assessment for both the control and diseased group. Haemato-biochemical parameters namely total erythrocyte count, haemoglobin, volume of packed red cells and serum creatinine kinase-MB were assessed for both the groups. The standard echocardiographic values and indices obtained were Left Ventricular Internal Diameter at End Diastole and Systole (2.73 ± 0.07 cm and 1.66 ± 0.08 cm), Interventricular Septum at End Diastole and Sytole (0.80 ± 0.02 cm and 1.07 ± 0.02 cm), Left Ventricular free wall thickness at End Diastole and Systole (0.78 ± 0.02 cm and 1.33 ± 0.03 cm), Fractional Shortening and Ejection Fraction (40.78 ± 2.66 % and 71.61 ± 2.89 %) respectively. Left Atrium to Aortic ratio in B and M-mode were 1.07 ± 0.01 cm and 0.74 ± 0.02 cm.
Out of twelve animals selected, nine were positive for Anaplasma spp., two were positive for Theileria spp. and one animal was positive for mixed infection of anaplasma and theileria. The normalized values of healthy animals were compared with cardiac dimensions of diseased animals. Significant difference was observed in the left atrium to aorta ratio in both B and M-mode of blood parasite affected animals in comparison to healthy animals.
The haematological parameters were significantly lower than healthy animals. Serum creatine kinase-MB values were significantly elevated in affected animals. The study established the normal echocardiographic parameters in
female adult Malabari goats. Variations in left atrium and aorta ratio and serum creatine kinase-MB values in affected animals suggested cardiac involvement in haemoparasitic diseases.
