The activists were protesting in front of the cowshed in Ajmer district against the death of the bovines and alleged that the cattle died due to hunger and lack of fodder.
Corporation's acting Health officer Satyanarayan Sharma and Revenue Officer Bhagwan Bachchani rushed to the spot, following which the activists blackened their faces with grease.
"There were some anti-social elements in the mob who smeared grease on my face when I went to the 'gaushala' on information of the death of cows and subsequent protest," Sharma said.
There were around 50 activists who were part of the protest, he said.
