32 ADVANTAGE OF RAPE IN COW-FEEDING. 



an acre, that rape ■\vliicli Lis own land ■would have supplied 

 liim witli in abundance ; and he has injured his clover, so 

 that he will lose half the benefit of it. But the advantag'e 

 of the rape is seen partic-ularly in this, that, notwithstanding- 

 the hig-h price he paid for it, it was better for him to buy it 

 than to feed his cow on straw ; even supposing- that he had 

 g-ot the straw for nothing-, which is very easily demon- 

 strated : 



For the 14 quarts produced by the rape feeding, at 1^^. a 



quart, comes to \s. 9d, 



The price paid for it only cost 2d. per day, to which add a half 

 stone of straw. Id. (being at the rate of IGfZ. per 112 lb. 

 which is above the general price of that article), and the ex- 

 pense, daily, comes to 3 



Leaving a clear profit, per day, arising from feeding on rape, of 1 6 



When the cow had been fed on straw, she only g-ave seven 

 quarts, and very soon would have given still less, the price 

 of which, daily, would be only lO^d. ; therefore, if he g-ot 

 the straw for nothing-, he would only have lO^d. a day by 

 the cow ; whereas, after paying- for the rape, he gained 

 18(1. ; but if he had to pay for the straw (the cow would 

 require three stone, which, at IGd. a cwt. would be Gd. and 

 deducting- this from lO^d. the price of the seven quarts of 

 milk), there woidd only be a profit by the cow of 4J//. a 

 day, in place of the 18^/. a day yielded by the rape. The 

 same thing- may be proved in regard to turnip feeding- in 

 winter. If a cow calves at November, and is fed on turnips, 

 she will keep up her milking ; but, if fed on straw, she will 

 fall ofl:' immediately to half the quantity. Now, allowing- 

 the acre of turnips to be worth 10/., which is more than any 

 other crop generally produces, and reckoning- the produce at 

 thirty tons (although by g'ood cultivation, Mr. Mitchell had 

 fifty-five tons to the acre last year) : — 



The 5 stone of turnips, which I reckon good daily feeding for 



a milch cow, would cost 2^d. 



And a stone of straw would cost, at 16i. a cwt 2 



Total cost per day for turnips and straw 4i 



Whereas, three stone of straw, which she would require if 

 fed on straw alone, at 16c/. per cwt. comes to Gd. a day ; 

 so that, by the use of turnips in winter, it appears you 

 can feed your cow (after allowing- 10/. an acre for the farm)
