II. By sheep', Onderstepoort Journal of Veterinary Research, vol. 27, no. 4, pp. 617-623.0330-2465http://hdl.handle.net/2263/58625The articles have been scanned in colour with a HP Scanjet 5590; 300dpi. Adobe Acrobat XI Pro was used to OCR the text and also for the merging and conversion to the final presentation PDF-format.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.en© 1958 ARC - Onderstepoort and Faculty of Veterinary Science, University of Pretoria (original). © 2016 University of Pretoria.
