Thalaivasal area of Attur Taluk, Salem District of Tamil Nadu is one of the major egg production centers of Tamil Nadu. In early 90's along with agricultural activity, few farmers started commercial layer farm with a capacity of 500 to 1000 layers. In this area, during the last 5 years period, the commercial hybrid layer population increased from 15,00,000 to 24,00,000 layers. Totally 33 commercial layers farms existed within 20 km radius in this area with a daily egg production of more than 19,00,000 eggs. All the layers are reared either in cage house or elevated cage house. By considering the requirement of poultry farmers, Tamil Nadu Veterinary Animal Sciences University established this centre from 12.07.2002 at Thalaivasal.
