AUTHOR'S METHOD OF FEEDING 177 



This is the total quantity to be fed per day at the close 

 of the week. The quantity of feed fed on the first day of 

 the week may gradually be varied to that fed on the last 

 day. Thus there will be a constant increase fed from 

 day to day. 



To determine the quantity of feed necessary for a bunch 

 of pigs at any time between the ages of two months and 

 nine months, the same method is followed as given. The 

 vertical lines in the cuts indicate the age of the pigs and 

 the stage of the period of feeding. The point at which 

 these intersect with the curves for the various nutrients 

 indicates the amount of these in pounds as specified by 

 the horizontal lines. Multiply these quantities by the 

 total live weight and proceed according to the directions 

 already given. 



As is clearly evident this method of feeding is intended 

 for pigs that have been well fed from the time they 

 learned to eat. If a feeder has a bunch of pigs that have 

 not been well fed, it may be necessary, in order to get 

 the best results, to start back a little farther than at the 

 point in the above cuts, pages 156 to 160, indicated by 

 the age of the pigs in question. 



In order to furnish variety and get large and econom- 

 ical gains, as large a number of feeds should be used in 

 the ration as possible. The greater the number of feeds 

 the better will be the ration. Of course, the greater the 

 number of feeds, the greater will be the amount oi work 

 in calculating the ration. In the above calculated ration 

 corn and barley are used for the sake of variety, both be- 

 ing carbonaceous concentrates. The proportion of these 

 two feeds may be governed to some extent by the 

 amounts available. Skim milk is likewise a feed of the 

 same class as soy beans.
