268 Oattle Problems. 



which accounts for considerable excess in bulk of yield 

 generally in the Netherland country cows. 



Selection of the best, which are generally most petted 

 in feeding, also had its share in collecting and concentrat- 

 ing the best herds of cows, in the best natural grass dis- 

 tricts, where, of course, dairying becomes most extensive 

 and concentrated in any country. 



The great industry, pains-taking care, and close economy 

 of the people in the Netherlands, in the management and 

 training of their cows, has much increased their yield, the 

 cows being milked very close, the demand for milk being 

 alway greater than the supply. This practice tends to de- 

 velop the largest yield that can be made, without reducing 

 flesh. Add to this, their pasturing in the night time, and 

 blanketing to prevent loss of blood-heat by evaporation, 

 and we have quite an effective series of influences contrib- 

 uting to increased bulk in the yield of Netherland or Hol- 

 steins, and Dutch cows. And the long succession of gen- 

 erations through which these influences have operated, has 

 led to the large size in the hind quarters, and arteries, 

 and in the udder and yield-marks, to correspond, being 

 more fixed, by long use, and inheritance, than in any 

 other example, or country, in so many cows. 



Considering the more watery and less nutritive quality 

 of the native feed in the low-coast country, we should of 

 course expect the Netherland cows to be more remarkable 

 for the quantity, than the quality of their yield, according 

 to the distensive influences already stated. 



Cows that have large digestive organs and artery sys- 

 tems will supply as much, and richer milk, when a richer 

 quality of feed of equal bulk is supplied to them. But 

 this will not, in this country, generally be done, in all 

 probability; hence some reduction in yield, in our dry 

 climate, by imported cows of this breed, and in their de- 

 scendants, is probable.
