The present study was conducted in apparently healthy Crossbred Holstein Friesian cows (n=40) to establish normal echocardiographic indices. The short axis M-mode echocardiography was conducted in non-sedated standing Crossbred Holstein Friesian cow using cardiac probe of 2.8 to 3.6 MHz from right parasternal short axis view. The clinico-physiological parameters were within the normal ranges. The mean ± SE of RVIDd was 3.40 ± 0.06 (2.61–4.42) cm, IVSd 1.88 ± 0.06 (0.95–3.17) cm, IVSs 2.72 ± 0.07 (1.77–3.81) cm, LVIDd 7.35 ± 0.14 (4.82–9.23) cm, LVIDs 4.37 ± 0.12 (2.04–5.87) cm, LVPWd 1.76 ± 0.06 (1.03–2.56) cm, LVPWs 2.80 ± 0.08 (1.58–3.96) cm, RWTd 0.50 ± 0.02 (0.35–0.85) cm, RWTs 1.31 ± 0.06 (0.84–2.83) cm, MWTd 1.89 ± 0.06 (1.23–3.03) cm, MWTs 2.76 ± 0.06 (1.85–3.74) cm, IVS % (46.17 ± 2.46), LVPW % (60.39 ± 2.64), LVM (1007.35 ± 53.78) g, LV myocardial fraction (0.33 ± 0.01), EPSS (0.86 ± 0.02) cm, FS % (40.68 ± 1.20), heart rate (66.15 ± 0.96) beats/min and body weight was 426.78 ± 7.79 kg. The correlation with the body weight revealed negative correlation (p<0.01) for the parameters viz RWTs.
