1.2.2.1 Analysis of feed and feed ingredients
Quality control laboratory should be well equipped for analysis of feed and feed ingredients. Since purchase and feed formulations are based on the analysis of raw materials, the highest degree of accuracy in analysis is desirable. All the samples should be analyzed in duplicate to minimize experimental error. The variation limit between duplication samples should be kept to minimum. In case of considerable variation, the samples should be re- analyzed. Accuracy of estimation can only be relied upon when pure reagents and precision instruments are used. The staff conducting analysis work should be qualified, experienced and efficient so that the analysis is completed as quickly as possible to facilitate prompt payment to the suppliers, usage of consignment and marketing of finished feed.
It is needless to emphasize that the authority of the animal nutrition officer should be final in the matter of accepting or rejecting raw materials and finished product. Keeping in view this important responsibility, it is felt that the animal nutrition officer should send reports directly to the administrative head of the organization.

Analysis report and reporting system
After the analysis of raw material and finished product, the results should be checked thoroughly and entered in the analysis register by the animal nutrition officer and not by any other staff of the quality control laboratory (Fig. 1.2). Analysis register and reports should be treated as confidential and kept under the safe custody of the animal nutrition officer.
