in which it is desirable to use the different commercial 

 supplements with the ordinary grains in order to have 

 balanced rations : 



(1) (4 parts com+1 part shorts) +10% tankage or meat- 

 meal. 



(2) (4 parts com+1 part shorts)+20% linseed-oil meal. 



(3) (2 parts com+1 part ground oats+1 part shorts)+5% 

 tankage. 



(4) (1 part com +2 parts skim-milk or buttermilk). 



(5) 3 parts com +2 parts ground oats +10 parts skim-milk 

 or buttermilk. 



(6) i ground barley, | ground oats, f shorts. 



(7) i ground barley, J shorts. 



(8) 1 part ground barley +1 part ground oats +2 parts 

 skim-milk or buttermilk. 



(9) i ground Kafir, | shorts. 



(10) I ground wheat, J ground oats, | shorts. 

 Note. — The above rations have nutritive ratios of 1 : 5.27 

 to 1 : 6.07. 



If the sows get a bite of grass, it will be a valuable 

 addition to the regular ration. Succulent feeds generally 

 are good milk-producers. Blue-grass, rye, rape, clover, 

 alfalfa, or other legumes are available in many parts of 

 the country at this time. Sows with fall pigs should have 

 access, if possible, to some legume, which will aid ma- 

 terially in properly balancing the grains fed. To make 

 certain that the sows receive suflScient mineral matter 

 in their diet, a mixture of charcoal, air-slacked lime, or 

 ground rock phosphate, and salt, in about the proportions 

 of 12 : 3 : 1, should be provided. 



The results at this time will depend very much on the 

 care and judgment of the feeder in determining the 

 amount fed. Sows that have a normal number of pigs 

 to nourish will ordinarily need full rations. The average 

 sow loses weight during this period, even when given all
