the case, special care in the purchase of feeds and some knowledge -of 

 their chemical comjposition will be found of paramount importance in 

 keeping the cost of feeding down to a point which will admit of a profit. 



Table Showing Average Composition of Foods Analyzed. 



The above table shows the average composition of the samples of 

 feeding-stuffs analysed in our laboratory. We have discussed each 

 table separately, and, where possible, have emphasized points of differ- 

 ence, etc., which we consider of greatest practical value to the feeder of 

 live stock. As mentioned in the introduction, the percentage of pro- 

 tein in a food is invariably considered of prime importance because our 

 home grown crops are more likely to be deficient in this than in any other 

 component. In selecting a food, therefore, we should aim at obtaining 

 the greatest amount of protein for our money. There are certain ser- 

 ious objections, however, to some of our feeding-stuffs which contain a very 

 large quantity of protein. Cotton seed meal, for example, contains, on 

 an average 44.18 per cent, of protein, but many of our best feeders do
