  • Abstract:

    The availability of the phosphorus in "bone pellets" and aluminium-iron rock phosphates was compared with bone meal. In evaluating the products, inorganic phosphorus content of the blood, live weight gains, phosphorus retention, X-ray photographs and the pathological and chemical examination of the bones of the sheep were used as criteria. From the overall results thus obtained it can be concluded that: (i) "Bone pellets" are as efficient as bone meal as a source of phosphorus. (ii) Aluminium-iron rock phosphate is practically useless in this respect and cannot replace bone meal in animal nutrition.
