While there are many nitrogenous feed stuffs on the market, the bulk 

 of experimental data as well as practical experience is very favorable 

 to the packing house by-products as a profitable source of protein to 

 balance the corn ration, either in dry lot feeding or when the pasture 

 does not furnish sufficient protein. 



Six cent pork can be produced at a handsome profit under prevailing 

 conditions if proper use is made of forage crops and dairy by-products. 



Experiment station work shows that a bushel of corn when properly 

 fed will produce 12 to 14 pounds of pork, hence when hogs are six cents 

 per pound we are getting about 80 cents per bushel for our corn. I am 

 firmly convinced that no farm yields the largest possible returns which 

 does not have a lot of well managed, properly fed swine." 



Geo. T. White: I would like to ask Prof. Kildee a little more 

 about the combination of corn and soy beans. 



Prof. Kildee : I will say that the soy beans are a crop that need 

 warm soil so we put them in with an early maturing variety of 

 corn. Last year we put them in along the first of June and this 

 year about the 20th of May. The corn was cheeked in and then 

 we drilled the soy beans right down the row. The vines grow very 

 rapidly and crowd out the weeds. "We are comparing this year 

 corn and soy beans and corn and Canada field peas. 



Mr. White : About what amount of seed do you use to the acre ? 



Prof. Kildee : About three stalks of corn to the hill and the peas 

 at the rate of half a bushel per acre. 



Mr. White : How would it do to mix the corn and peas in the 

 proper proportion? Would the peas go to the bottom? 



Prof. Kildee : I think likely they would. We have not tried it. 

 It does not take long to put them in as we did and you have a good 

 crop of corn. 



Mr. Hoffman : Have you ever tried raising the soy beans alone ? 



Prof. Kildee : No, not as yet. Some people have secured very 

 good results, especially down in Missouri, putting them in late and 

 then turning in the hogs and getting the forage as well as the 

 beans, but we have not tried that here. 



Mr. Hoffman : We have put them in and used them for winter 

 feed. I understand a pound of soy beans would equal a pound 

 of oil meal. 



Prof. Kildee: Practically so. 



Mr. Hoffman: How do your soy beans and cow 7 peas compare 1 ? 



Prof. Kildee : There is not a great deal of difference in the 

 economic gain, but we secured somewhat better results with the soy 

 beans. In the case of the peas there are more vines, but fewer 

 pods. There will be fewer peas than beans.
