FEEDING OF DAIBY COWS. 173 



tfie milk which each cow gives for dairy purposes, 

 there is also her annual calf, the phosphates in the 

 bones of which must also come out of the pasture. It 

 is certain that in the bones of the calf, and in the 

 milk, each cow would deprive the pasture of at least 

 60 or 60 lbs. of bono earth, or phosphate of lime, in 

 each year. For th< - is it is, that bones, as has 



been indicateti, are > ly to prove of great ad- 



vantage as a manure on worn out pastures, and also 

 on meadows that are used in the autumn for feeding. 

 Applied as dust, or still better dissolved in sulphuric 

 acid, a few bushels per acre ( in the latter case two is 

 enough) have been found to nrotluce a most wonder- 

 ful eiiiect; in many cases doubling and even tripling 

 the value of pastures, within a year or two after the 

 application. 



The diirLTcnt properties of milk which have beai 

 noticed, sui^gest one or two hints relative to the feed- 

 ing of milch cows. We have seen that the quantity 

 of milk may be increased by feeding with watery suc- 

 culent food. There is no doubt but the quantity of 

 butter would he greatly augmented, by feeding in tlia 

 same I : ^ tor fattening, with food rich in oily or

In feetling with ouj, i.-w.i, t.,.t i.-i lo be taken that 

 it is not of a nature to communicate any unpleasant 

 flavor to the butter. Liaseed cake is an instance of 

 this; a small projjortion of it. ijiven with other food,
