PROTEID FROM CASTOR BEANS

and leguminous seeds with materials containing starch and 

 sugar in excess. 



A new source of Proteid has recently been discovered 

 in Castor seed as extracted in practically a state of purity 

 (80 per cent.) by " Mitchell's Process," and as the raw material 

 is plentiful and comparatively cheap, it is anticipated that 

 this new vegetable proteid will enable the nutritive ratio in 

 compounded foods to be easily and economically balanced to 

 suit the varying requirements as shown on Wolff's table 

 (p. 264). The following is an example of how the com- 

 pounding of foods to their correct nutritive ratio is simplified 

 by adding a pure proteid. 



This satisfactory result in compounding food to its 

 correct " nutritive ratio " would be attained at a cost not 

 exceeding 155. per ton ; and by taking A at $ per ton, and 

 B at 5, 155., and calculating the food unit cost as explained, 

 the relative cost would be A 133. and B 93. 6d. By paying 

 1 5 per cent, extra on cost the farmer gets an advantage on 

 food value of 27 per cent., or 12 per cent, of actual gain. 



There are three common methods of arranging cattle in 

 a house to feed : 



ist, Tying by the neck in a byre, either in stalls or with- 

 out divisions between them. 



2nd, Putting them in loose boxes, one in each. 



3/-Y/, Leaving them untied, several together, in a shed, 

 with an open door and an open or partially covered court. 



In a byre they may be arranged, if in more than one row, 

 either with the heads turned towards a passage up the centre 

 of the house, or with the heads to the side walls, with or 

 without a feeding passage in front. It is a mistake to have
