NOTES ON OSTEO-MALACIA (BONE -CHE WING). 23 



Summary. 



1. Soils from the affected areas contain less nitrogen, lime, potash, and 



phosphoric acid than do those from non-affected areas. 



2. The ash of the grass from affected areas contains less lime, potash, and 



phosphoric acid than do those from unaffected areas. 



3. The amount of mineral ingredients (lime, potash, and phosphoric acid) 



supplied to a cow in a full ration of grass from affected areas does not 

 supply as much lime, potash, and phosphoric acid as is required by an 

 ordinary healthy cow, whereas the mineral ingredients in a ration of 

 grass from the non-affected areas do supply these. 



4. Bones of animals raised on affected areas contain less lime and less phos- 



phoric acid than do those raised on non-affected areas. 



Remedial Measures. 



1. The systematic manuring of pastures, with the view to increasing the 



mineral matter content of the grass. 



2. The addition to the daily ration of the animals of i oz. phosphoric acid 



(P 2 O 5 ), 1 oz. lime (CaO), 1 oz. potash (KsO). (These quantities can 

 be roughly supplied by the addition to the daily ration of about 2 oz. 

 sterilized bonedust, or If oz. bone-char, together with ^ oz. slaked lime 

 and 2 oz. sulphate of potash.) 



3. The free use of cattle licks, made up as follow : 



Bone-ash, 1 cwt. 



Common salt, 5 or 6 Ib. 



Sulphate of iron, 4 Ib. 



Molasses, sufficient to make the mass coherent and to flavour it.
