Present investigation was carried out to study the behaviour in relation to sickness in vrindavani calves. All Vrindavani calves (Age 0 to 3 month) born between January to August 2018 was selected. During this period approximate 80 calves were born. All calves were examined daily for clinical sign of umbilical infections. In our study we observed 10 calves affected with umbilical infection (navel-ill). The calves suffering from umbilical infection were considered as a diseased calf during study period. For each diseased calf, a healthy calf on the same date, of the same breed, and similar age was identified as the matched pair. After clinical examination all experimental calves were divided into 2 equal groups viz., healthy (Control) and Sick (Treatment). Behavioral observations were observed during day hours by CCTV camera. Calves with navel-ill more likely to be short lying than their healthy cohorts (p<0.05). Ventral lying and short lying were observed in 20% (2/10) and 40% (4/10) of navel-ill calves, respectively. Ventral lying was observed in 50% (5/10) of calves in the control group. There was no difference in the proportion of calves ventral lying in the navel-ill and control groups (p>0.05). Lateral lying and lying with neck extended was observed in 30 % (3/10) calves and 10 % (1/10) calf in the navel-ill group, respectively. For the human approach test, 60% (6/10) of calves never approached the observer, 10% (1/10) approached the observer during only one observation period, 10% (1/10) approached the observer at two of the observation periods, and 20 % (2/10) of calves approached the observer during all three observation periods. In vigilance test significant (p<0.05) difference were observed in face response.
