P Vasanthakumar, D Chandrasekaran, M R Purushothaman, D Rajendran, C Kathirvealn.


Quality of poultry feeds influence the nutrient utilization and production performance of birds. Adulteration of animal proteins with leather industry wastes reduces the egg production in commercial layers and growth in broilers. A study conducted in Namakkal area of Tamil Nadu to assess the incidence of adulteration of animal proteins with leather meal revealed that 30.7 % of fish meal, 52.4 % of meat and bone meal and 56.3 % of meat meal samples were found to be adulterated with leather meal. Since the animal protein sources such as fish meal, meat meal and meat & bone meal sold in the market are mostly adulterated with leather meal, feed samples may be tested for adulteration with leather meal before using for feed manufacturing.

Key words: fish meal – meat and bone meal – adulteration – leather meal - poultry
