equivaleDt is £6 13s. The cost per unit of starch equivalent is 

 therefore £6 13s. divided by 68, or almost exactly 2s. per unit. 



The average price of maize at present is round about £2 per 

 quarter, which is equivalent to £9 6s. 8d. per ton. Maize con- 

 tains 81 units of starch equivalent per ton and its manurial 

 value is 17s. per ton. The net cost of the 81 units of starch 

 equivalent is therefore £S 9s. 8d. The cost per unit of starch 

 equivalent is therefore £'8 9s. 8d. divided by 81, or almost 

 exactlv 2s. 



Starch equivalent costs 2s. per unit in both middlings and 

 maize, the two starchy foods most largely used. 



Feeding Value of Home-Grown Corn. — Average samples of 

 sound wheat contain 72 units of starch equivalent per ton. At 

 the present price of starch equivalent in maize and middlings, 

 namely, 2s. per unit, the 72 units in 1 ton of w^heat are worth 

 £7 4s. Adding the manurial value oi £1 per ton, wheat for 

 home consumption should be worth £8 4s. per ton, or 37s. per 

 quarter of 504 lb. This means that any farmer who awns suitable 

 live stock to consume wheat, and is not in urgent need of ready 

 cash, would be well advised to grind or crush his wheat for home 

 consumption rather than to buy maize or middlings unless he 

 could sell his wheat for considerably more than 37s. per quarter 

 so as to pay for the delivery of the wheat and the carriage of 

 other feeding stuffs bought in its place. 



The following table gives t lie pi'ice below which it is more 

 economical to keep com and potatoes for home consumption 

 rather than to sell them and buy maize or middlings at current 

 prices : — 



Wheat ... 37/- per quarter of 504 lb. > plus in each case an addition sufli- 

 Rye ... 37/- ,. ,, 504 lb. / cient to pay for the cost of 



Barley ... 32/- .. .. 448 lb. , delivering the articles sold and 



Oats ... 21/- .. .. 33(1 lb. \ fetching home the feeding stuffs 



Potatoes ... 40/- per ton ... ... ' bought in their jilace. 



Having arrived at the prices which determine the relative 

 economy of sale or home consumption, the next point is to dis- 

 cuss the use of the various article? in case it is decided to feed 

 them at home. 



Wheat. — It is commonly accepted that wheat is not a safe food 

 for horses, and its use is not recommended for sheep. It can, 

 however, be used successfully for pigs and for dairy cows. 



For young pigs it may be used up to about one-quarter of their 

 total ration, and it may be given either roughlv ground together 

 with the rest of the ration in the dry state, or more finely ground 

 and made into slop.
