266 FEEDING ANIMALS. 



various foods, to yield 100 Ibs. increase in live weight, and 

 whether this would be less or more than the 100 Ibs. 

 increase would sell for ? Well-bred and moderately- 

 fattened oxen should yield 58 to 60 per cent, carcass in 

 fasted live weight ; very fat oxen may yield from 65 to 70 

 per cent. But of the increase obtained during what may 

 be called the fattening period of moderately-fattened oxen, 

 it may be reckoned that about 70 per cent, will be carcass. 

 Supposing you get 8d. per pound for this, the selling value 

 of your 100 Ibs. increase in live weight will be 46s. 8d. 

 Now, I think if you try to make up 1,250 Ibs. of dry sub- 

 stance by a suitable fattening mixture of the foregoing 

 foods, you will find that it will cost you considerably more 

 than 46s. 8d. Even if roots alone were used, which would 

 not be considered good fattening food, the cost would be 

 more if they were reckoned at their selling price, though 

 less if taken at what is called their 'consuming value.' 

 But with no good fattening mixture of cake or corn, hay, 

 chaff and roots could 1,250 Ibs. of dry matter be obtained 

 for anything approaching the sum I have estimated as the 

 value of the increase it will produce. It is further to be 

 borne in mind that, weight for weight, store stock is gen- 

 erally dearer than fat stock. You have also to add to the 

 cost of the food the various other charges, such as rent of 

 buildings, appliances, attendance, and risk. Taking all these 

 things into account, I think it is evident that there must 

 always be a very considerable proportion of the cost of feed- 

 ing, although varying greatly according to circumstances, 

 which must be taken to represent the cost of the manure." 

 Me then speaks of his tables, published some years ago, 

 and many times republished in this country, in reference to 

 the value of various cattle foods in the production of ma- 

 nure. He says this table of manure value was much criti- 

 cised in England, as being too high an estimate ; and as an 

 answer to this he says :
