Milk is considered one of the healthy drinks that humans consume during the prime of their lives, and it is a rich source of essential elements and compounds. In this research, the concentrations of both calcium and magnesium were estimated for different types of animal milk (camel, cow, sheep, goat) using the EDTA complexity titration method. In addition to making a comparison of some of their physical and chemical properties, the results showed that the highest concentration of both calcium and magnesium was in the sheep’s milk sample (1816.245ppm) and (684.05ppm, respectively, while the lowest concentration of calcium was in the cow’s milk sample (1102.892ppm). The lowest concentration of magnesium was in the camel milk sample (39.6607 ppm), and the pH of all milk samples was similar and between (6.92-6.5)While the electrical conductivity (EC) and the percentage of total dissolved salts (TDS) were the highest value in the goat milk sample (7550 µs/cm) (4832ppm), respectively, while the lowest value was in the sheep milk sample (4580 µs/cm). (2931.2ppm) respectively, and they were all within the limits indicated in the Jordanian standard for “fresh” raw milk, which included camel milk along with milk from cows, buffalo, sheep and goats (Jordanian Standards and Metrology Institution, 2003), as well as the Libyan standard. For “fresh” raw cow’s milk (National Center for Standardization and Standardization, 2013). We have noticed that the results recorded in previous studies and practically recorded in this research are almost similar, with the exception of the concentration of magnesium in cow’s milk, which was higher in concentration than in goat’s milk. The reason for this may be due to the genetic factor, as the rate of milk production and the concentration of some elements and vitamins vary according to the breed to which these animals belong. This is in addition to the animals’ food, the environment in which they live, and their age. All of these factors may affect the concentration of these elements in the milk of various animals, which is considered a beneficial food for humans and an important source of calcium and magnesium, which are important for human health.
