3.2    Determining excess or short usage of raw materials

Batching operation in most of the plants is now-a-days automatic and controlled through a computerized batch weighing system. Accuracy level of 5 to 10 kg is possible. If the error is more than 10 kg, it should be pointed out to the production management for rectification. Adopting   the latest technology available in feed industry, now-a - days, all the new feed plants are equipped with auto batching operation, automatic bagging machine for bag filling, energy efficient equipment, new design empty gunny bag cleaning machine, and hence the handling and process losses are reduced drastically. The verification is made from the daily raw materials usage statement and actually calculated quantity as per the formula. The difference between two statements gives daily excess/ short usage of raw materials. This should either be assessed by the production superintendent or the animal nutrition officer. If this verification is not done, it will reflect on the stocking of ingredients and the chemical composition of finished products may vary beyond permissible limits. Verification also helps in controlling  the usage of urea, minerals and vitamins, and production cost of feed.
