408 APPENDIX. HORSFALL'S SYSTEM. 



every element suited to her wants and purposes, with 

 the exception of the nitrogenous principle only, lower- 

 ing her condition, and likewise her yield of milk, till it 

 approaches a quantity for which her food enables her 

 to supply a due proportion of caseine. 



About the 20th of April, the cow's yield being re- 

 duced to 9 quarts per day, her food was changed to 

 steamed mixture. Soon after this her yield increased 

 to 11 quarts per day. Her weight, April 28th, 9 cwt. j 

 May 16th, 9 cwt. 14 Ibs.: yield of milk, 11 quarts. 



I now introduce the dairy statistics of Mr. Alcock, of 

 Aireville, Skipton, who has for some time been prac- 

 tising my method of treatment, with such modifications 

 as are suited to his circumstances. 



During the winter season, Mr. Alcock's food consisted 

 of mangold, of which he gave 20 Ibs. per day to each, 

 uncooked, together with steamed food ad libitum, con- 

 sisting of wheat and bean straw, and shells of oats. 



Carob bean and Indian meal, for each, . . 3 Ibs. per day. 



Bran and malt-combs, ....... 1 " " " 



Bean-meal, .......... 3 " " " 



Rape-cake,* .......... 3 " " " 



Of extra food, 



From March 19, when his store of mangold was ex- 

 hausted, he increased his supply of Indian meal to 4 

 Ibs. per day, and omitted the carob bean. 



During the month of January, Mr. Alcock obtained 

 from 759 quarts of milk 1323 oz. of butter, being from 

 each 16 quarts 26| oz. ; during February and March, 

 from 7368 quarts of milk 12,453 oz. of butter, or from 

 each 16 quarts fully 27 oz. : so that rather less than 

 9J quarts of milk have produced 16 oz. of butter. 

 The average produce from each quart of cream was 

 20J oz. 



Mr. Alcock fattens his cows whilst giving milk, and 

 sells them whilst giving 4 to 6 quarts per day. He 



* The rape-cake used by Mr. Alcock was of foreign manufacture, evi- 

 dently rich in oil, but containing mustard, and on this account supplied in 

 less proportion.
