Objective: To investigate the calcium and phosphorus contents of four domestic animals used as sources of meat in Nigeria. Methods: The calcium contents of the body parts of the animals were determined using atomic absorption spectrometer. Their phosphorus contents were determined calorimetrically using the molybdenum blue method.. Results: The calcium and phosphorus contents were significantly higher in the bone samples than in the other animal parts investigated (P<0.05). The calcium contents of all the edible parts were higher in chicken than in the other animals. High calcium and phosphorus contents were detected in the faeces of chicken and goat, and that of cattle and goat, respectively. Low calcium and phosphorus contents were detected in the urine samples. Calcium : phosphorus ratios calculated for the bones of chicken, cattle and goat were satisfactory. Conclusions: In conclusion, calcium and phosphorus contents of the animal parts vary significantly and their relative contents may be related to the animal's diet. Chicken parts may be the preferred dietary source of these minerals. This study highlights the need for routine investigation of the mineral contents of food, which is necessary for proper nutritional guidelines.
