Pastures for Hogs.

is shown by the fact that when clover or alfalfa was made the prin- 

 cipal pasture 36.5 per cent, of our correspondents feed corn alone to 

 spring shoats on pasture, while of those who used timothy or blue 

 grass even when mixed to a greater or less extent with red or white 

 clover, only 28.9 per cent, feed corn alone. When there is not 

 enough clover in a pasture to furnish a large proportion of the forage, 

 there is a need, especially with shoats, for a feed consisting of more 

 than corn alone. The amount of clover available determines to a large 

 extent the needs for these supplemental feeds. This is shown very 

 clearly in an experiment, conducted at the Iowa Experiment Station, 

 with the hogs running on timothy pasture and fed corn and supple- 

 mental feeds, and another lot on clover pasture and fed corn alone. 

 The summary of the experiment is given below : 



IOWA BULLETIN, NO. 91. 

 112 days, 10 pigs per lot. 



It will be noted that the gains made on clover pasture and corn 

 were faster than those made on timothy pasture and corn and shorts, 

 but not as fast as those on timothy pasture and fed corn and tankage 

 or corn and meat meal. Based on this data, corn alone fed on a clover 

 pasture is equal to a ration of one-half corn, one-half shorts on timothy 

 pasture, and superior to a ration two-thirds corn, one-third shorts on 

 the same kind of pasture. The value of feeding some grain containing 

 an excess of protein, to hogs on timothy pasture, is shown by the 

 more rapid and more economical gains made by the pigs fed corn and 

 shorts and corn and meat meal or tankage. The rate of gain was in- 

 creased 30 to 50 per cent, by using a meat by-product, and from 12 

 to 20 per cent, by using shorts with corn. 



The above results are borne out by the practice of the farmers 

 as shown by the reports of those using blue grass or timothy with 

 more or less clover as a pasture for pigs after weaning time, and their 

 method of feeding is shown by their answ^ers to the question, "How
