Deficiency of phosphorus and other minerals can effect animal growth. These mineral salts can be supplied to animals in a variety of ways. Lack of these elements effects the breeding and working ability of animals. The gradual decline in milk and meat production is also due to the deficiency of these minerals. Cattle breeders should ensure the balanced use of phosphorus fertilizers in the land while cultivating green fodder, so as to increase the productivity of milk and meat of livestock.
