In this research, we address one of the most important and complex issues, which is the issue of the health effects of using animal materials in feed. We conclude that the materials extracted from the bones, hooves and feathers of deceased persons, which are included in the feed mixtures, may cause changes in blood glucose content, and in its content of kidney protein and creatinine. It may also lead to significant differences in the number of red blood cells, albumin, and urea creatinine, and in the concentration of calcium and phosphorous in the blood. These changes take from the health of a person until he is infected in his blood, which may affect the functions of his organs, especially the liver, pancreas and kidneys. Accordingly, more scrutiny must be exercised regarding the permissibility of using these materials as animal feed. It also improves the further medical examination of the matter. The researcher adopted the descriptive approach in the study stages, relying on the inferential method and the deductive method in the issue.
