Evaluation of content and ratio of calcium and phosphorus in commercially available pet food for dogs and cats
Calcium, phosphorus and vitamin D are essential nutrients for dogs and cats, and therefore, they need to be provided in the diet in adequate amounts and in bioavailable forms. Generally, calcium and phosphorus are discussed together because of their close relationship, particularly in the bone health. The objective of this study was to determine calcium and phosphorus contents in commercially available pet food for dogs and cats marketed in Serbia, during 2022. The contents of calcium and phosphorus in examined animal feeds were determined by using standard ISO procedures. According to national and regulation of EU all results were in permitted content ranges. The quality and safety of pet food are of great importance to pet health and welfare over their prolonged lives. These results could be discussed from a nutritional, ecological and economic point of view in order to meet optimal formulation of diets.
