For the first time tablet computers were used for conduct of 20th livestock census.
The production of major livestock products (MLP) namely milk, eggs, meat and wool is estimated on the basis of annual sample surveys conducted under the Central Sector Scheme “Integrated Sample Survey”. The scheme is implemented by the Department of Animal Husbandry and Dairying through State Animal Husbandry Departments. All States & UTs are implementing the scheme. Surveys conducted in entire rural and urban areas of the States and UTs. The survey period is from March to February and the entire period of one year is divided into 4 months each.
