134 AMERICAN DAIRYING. 



Here is 20 per cent better results obtained from 

 the combination of foods. And this is not all 

 the meat in this nut by any means, as the 

 farmer can feed three times as many pigs when 

 he feeds one bushel of corn to 100 lbs. of skim- 

 milk as he can when he feeds clear skim- 

 milk, as the bushel of corn has in this case 

 twice the feeding value of the 100 lbs. of skim- 

 milk. I think it is fair to conclude from this 

 work that there is twice the profit when the 

 skim-milk is fed with the proper amount of 

 grain food than when fed alone. This is in line 

 with my own experience and also with much 

 experiment station work. Mr. Goodrich is a 

 farmer and did this work for his own informa- 

 tion. 



Salt, ashes, and copperas. — Keep a mixture 

 of ashes, salt, and copperas by the pigs and 

 hogs at all times. Mix one bushel of ashes, 

 eight quarts of salt, and four quarts of copperas. 

 Put in a trough where it is dry and accessible 

 at all times. It will keep them clear of worms 

 and lice and help promote thrift. My hogs 

 consume a barrel of copperas annually. 



Skim-milk for calves. — Skim-milk as a food 

 for calves, and especially separator skim-milk, 

 is underestimated very much by dairymen in 

 general, I teach the calves to drink their 

 mother's milk. The calf must have the first 

 milk from its mother if not allowed to suck.
