Phosphorus (P) has a key role in production and reproduction performance of dairy animals. However, feeding of high levels of dietary P has no additional benefits to dairy animals but this practice generally leads to more excretion of P, which in turn causes environmental pollution as P accelerate eutrophication of surface waters. A practicable and cost-effective approach to managing P level in the diet of dairy animals is required to minimize excretion of P in manure without impairing animal performance. Therefore, to access the requirement of P supplementation to dairy animals in Punjab various reports of P status in soils, feed and fodders were reviewed and its supply to the dairy animals were accessed. From this study, it can be concluded that the soil and plants of various districts of Punjab are deficit in P and there is a need of P supplementation either in the form of mineral mixture (60-100 g/d) or any other P source in the diet of dairy animals.
