This laboratory manual provides essential protocols and procedures for analyzing animal feed in the Animal Nutrition Laboratory at Wollo University. It is tailored to assist researchers, technical assistants, and students in evaluating feed quality to optimize ruminant nutrition, especially under arid conditions where feed costs impact livestock productivity. The manual covers safety guidelines, sample preparation, and detailed procedures for determining moisture, dry matter, crude protein, crude fiber, ether extract, and ash content in animal feed samples. Special emphasis is placed on using the Kjeldahl method for protein determination and the Soxhlet apparatus for fat extraction. Additionally, the manual includes methods for producing urea molasses blocks, a valuable supplementary feed. Physical evaluation techniques such as assessing color, texture, odor, and mold presence are highlighted for rapid feed quality assessment, ensuring safe and effective diets.
