Abstract :

Evaluation of cardiac echocardiography in domestic rabbits and comparison of normal echocardiographic indices in male and female rabbits The assessment of the normal heart parameters in healthy animals for evaluation of heart structure, function and cardiovascular disease are necessary. The domestic rabbit (Oryctolagus cuniculus) is becoming increasingly popular as a companion animal. 100 rabbits between 6 to 12 month of age without sedation or anesthesia were used in this study In guided M-mode echocardiography, the following values were obtained: IVSd 2.54±0.63 mm; IVSs 3.42±0.68 mm; LVIDd 15.54±2.96 mm; LVIDs 10.97±2.25 mm; LVFWd 2.35±0.50 mm; LVFWs 3.16±0.79 mm; LVIDd 15.542±2.969 mm; LVIDs 10.970±2.253 mm; EF% 60.07±6.80; FS% 29.60±4.82. All comparisons of echocardiographic dimensions are summarized in Table 1. The mean values of LVIDs of the male population were significantly higher than those of the female population. The following measurements differed significantly between male and female rabbits: LVIDd, LVWFd in this study. These measurements can be used as standard and reference values for evaluation of cardiovascular disorders of Domestic rabbits(Oryctolagus cuniculus) nonanaesthetised.
