author's method of feeding 197 



In the first experiment, at the Illinois Experiment Sta- 

 tion, by which this system was developed, where the 

 pigs were fed in this way they made 28.6 per cent larger 

 gains during the growing period than pigs that were fed 

 according to the Wolff-Lehmann Standard. At the same 

 time they consumed 5.4 per cent, less feed. Thus it will be 

 seen that this system of feeding produced an advantage of 

 about one-third in its favor. In one of the latest experi- 

 ments of the series about 44 per cent, greater gains in 

 live weight were made. Even though the development 

 of this new standard has not yet been completed, it has 

 been shown recently that a pig at eight months of age 

 can be made to weigh 300 pounds and it is believed that 

 it ought not require more than 1,200 pounds of feed to 

 do it. 



OFF-HAND FEEDING. 

 Without going into details, as given previously in 

 this chapter, swine may be divided into mature hogs, 

 young breeding hogs, between the ages of one and two 

 years that are still growing, and growing pigs and shotes. 

 The latter class should be subdivided into those that are 

 being fed for market and those that are being developed 

 for breeding purposes. The latter should have less feed 

 than the former. The rations for all hogs should con- 

 tain plenty of mineral matter. Young and growing pigs, 

 as well as breeding hogs, need a comparatively large 

 quantity of water while the fattening hog needs less. 

 For mature breeding stock there is probably sufficient 

 protein in the non-nitrogenous feeds. The rations for 

 young and growing pigs should be made up of a mixture 

 of carbonaceous and nitrogenous feeds, using in general 

 from one to six times the quantity of the former that is 

 used of the latter.
