wool for the lot receiving the oat ration. The second lot also con- 

 sumed more feed per pound of gain. 



Feeding Value for Dairy Cows. Soy-bean meal has been found 

 a most excellent feed for dairy cows. The Massachusetts Agricultural 

 Experiment Station compared soy-bean meal and cotton-seed meal, 

 using the same ration otherwise. The quantity of milk produced 

 from the soy-bean ration was slightly larger. The butter from the 

 cows fed cotton-seed meal was of firmer texture, but not nearly as 

 good otherwise as the butter from the cows fed soy-bean meal. The 

 test indicated that soy-bean meal was superior to cotton-seed meal for 

 both milk and butter production. 



At the Tennessee Agricultural Experiment Station three groups 

 of cows of two lots each were fed to compare (1) soy-bean straw and 

 corn stover; (2) soy-bean hay and alfalfa hay, and (3) soy-bean 

 meal and cotton-seed meal. There was no chance in these experi- 

 ments for the individuality of the animals to affect the results, as 

 each lot was fed on the separate rations at different periods in the 

 course of the experiments. Soy-bean straw was found very palatable 

 and superior to corn stover as a feed. More feed was eaten in the 

 case of the soy-bean straw, but the cost of the feeds consumed during 

 a thirty-day period was practically the same. The soy-bean ration 

 produced 12 per cent more milk and 14 per cent more butter fat, so 

 that the cost of a gallon of milk was 1.2 cents less and of a pound 

 of butter fat 2.1 cents less than when corn stover was fed as roughage. 

 In the comparison of soy-bean hay and alfalfa hay, these substances 

 were fed in combination with corn silage and corn-and-cob meal. 

 Each lot of cows consisted of four Jerseys, and the test lasted through 

 three periods of thirty days each. At the end of this time the results 

 were in favor of the soy-bean hay by 245 pounds of milk and 20.5 

 pounds of butter fat. This result indicates a slight superiority of 

 soy-bean hay over alfalfa hay. In the trial for the comparison of soy- 

 bean meal and cotton-seed meal the yield both of milk and of butter 

 fat was about 5 per cent greater for the soy-bean meal. 



Feeding Value for Hogs. The Wisconsin Agricultural Experi- 

 ment Station compared soy j bean meal and wheat middlings for pork 

 production in three separate experiments in as many years. Two- 

 thirds of the grain ration was corn meal in each case. In each of the 

 experiments the largest gains were made on the soy-bean rations. 

 Soy-beans proved about 10 per cent superior to wheat middlings for 

 pork production, figuring the cost of the feeds as the same. 



The Indiana Agricultural Experiment Station compared rations 

 of 2 parts of corn meal and 1 part of soy-bean meal with corn meal 

 and wheat middlings in equal proportions and with 5 parts of corn 

 meal and 1 part of tankage for pork production. The soy-bean ration 

 produced the largest daily gains, and this with the smallest quantity 

 of feed consumed for each pound of gain. 



The Kansas Agricultural Experiment Station has several times 

 tested the value of soy-bean meal in combination with corn meal and 

 with kafir meal in comparison with the two latter fields alone in feed- 

 ing hogs. The feeds were mixed in the proportion of four-fifths
