With the crackdown on slaughterhouses by the state government, authorities have been forced to switch over to mutton and chicken which is not going down well with the big cats and is also burdening the exchequer.
Deputy director of Etawah Lion Safari Anil Patel said that they were facing a problem arranging food for eight lions including cubs.
"About 50 kgs of meat is required daily and instead of the buffalo meat which is of their liking they are being provided mutton and chicken," Mr Patel said adding that arrangements are being made to rope in fresh suppliers soon.
Authorities at the Lucknow zoo said the supply of meat has been affected since the past two days and a decision has been taken to switch over to mutton and chicken until the issue gets resolved.
Zoo authorities said they require 235 kgs of buffalo meat every day, but the supply for the past two days is just 80 kgs.
As the meat delivery has been hit hard, the zoo administration is now looking for a different contractor who can source meat from authorised places outside the city to meet the demand.
Etawah officials said that mutton and chicken was also not an adequate diet for the big cats due to low fat content.
The average consumption of a big cat is 8 to 10 kgs of buffalo meat daily which is hard to meet through mutton and chicken.
