APPENDIX. HORSFALL'S SYSTEM. 



I omit the minerals, which are observed to be in 

 excess of the requirements. 



For the maintenance of a fair-sized cow, for one day, 

 in a normal state, the following elements seem ade- 

 quate : 



When cows are in milk, there occurs a much greater 

 activity of the functions ; they eat and drink more, 

 evacuate more excrement, and, in all probability, spend 

 considerably more food in respiration. Whilst the 

 17.60 Ibs. per day dry matter in 20 Ibs. of hay are found 

 adequate for the maintenance of a cow in a store state, 

 the six cows in milk have eaten on the average 21.37 

 Ibs. solid matter per day during the 27| weeks. When 

 I have fattened cattle together with a number of milch 

 cows of similar size, which gave on an average eight 

 quarts of milk per day, the whole being fed with moist 

 steamed food, and receiving the same allowance of 

 green food, I have found the fattening cattle refuse 

 water, whilst the milch cows on the average drank 

 upwards of 40 pounds per day of water given sepa- 

 rately. The eight quarts of milk contain only about 

 17.58 Ibs. of water ; still, in several analyses of excrement, 

 I have noticed little difference in the percentage of 

 moisture in that from the fattening animals as compared 

 with that from cows giving milk.
