Abstract:
The present study on “Waste management system evaluation in commercial dairy farms” was conducted to assess the usefulness of the different waste management methods adopted in dairy farms of Kerala. Study area comprised of Thrissur, Malappuram and Ernakulam districts and adjoining area of central and northern Kerala. Forty five dairy farms were identified and visited in and their profile of the study area .Data regarding general outlay of the farms selected management practices in the farm, livestock details and existing waste management methods in the farms were collected and studied. The dairy farms under study were classified based on the animal holding capacity as those with less than six animals (class 1), 6-20 animals (class 2), 21-50 animals (class 3)and 51-100 animals (class 4), and above 100 animals (class 5). Among the 45 farms under study, four per cent belonged to class 1, forty nine per cent belonged to class 2, thirty five belonged to class 3, six per cent farms came under the classes 4 and 5.There was no commercialization of waste management methods adopted by the farms. The majority farms had dung pit as waste disposal method and no regularity in dung removal from pit, it was upon demand. Regarding the soil quality, there was no significant difference in the soil nutrients quantity between different groups of farms. Regarding water quality, the water samples collected from the nearby water bodies were inferior in quality in terms of microbiology and BOD. Air quality stands below the permitted standards in all groups of farms. Intervention by the government, local bodies and scientific institutions must be made in this area supporting the farmers to develop awareness in this serious issue and also providing necessary technical and financial support for the farmers to construct proper waste management systems such as compost unit as well as biogas plants because they provide a support for the most efficient waste management system in a dairy farm proving that waste is wealth
