Quality control of incoming ingredients is crucial to predicting the quality of a finished feed. A large number of raw materials are considered for the production of cattle feed, based on their chemical composition and current price structure. The processing techniques, such as oil extraction, polishing etc., are the factors, which affect the composition of raw materials. Adulteration of raw materials is also quite common. It is, therefore, desirable to lay down specifications for purchase of standard raw materials and negotiate prices effectively. Sampling of material for analysis should be such that it represents the consignment. Otherwise, the entire purpose of quality control will be defeated. It may be noted that the quality of a cattle feed will be no better than the qualities of the individual ingredients used in the formula. Hence, it is essential to observe strict quality control measures for purchase of raw materials.
