on pasture, or when fed skim milk with a grain ration. In the winter season 

 pigs should be fed in a dry pen, but they will make faster and more economical 

 gains if they have access to a little alfalfa hay. 



Whole corn compared with corn meal for fattening pigs, W. A. Henry 

 {Wisconsin Sta. Rpt. 1905, pp. 16-20). — Five pigs fed equal parts of heavy 

 wheat middlings and corn meal mixed to a slop with water gained 106 lbs. in 

 14 weeks, 5.77 lbs. of grain being required per pound of gain, as compared with 

 a gain of 12.3.6 lbs. per head in the case of a similar lot fed a mixture of equal 

 parts of dry wheat middlings and shelled corn, 5.2.3 lbs. of grain being re- 

 quired per pound of gain. 



Summarizing the present test and earlier investigations (E. S. R., 16, p. 808), 

 the average gain on the dry ration has been 96.8 lbs. per head and the feed 

 eaten per pound of gain 5.18 lbs. Similar values on the ground corn and wheat 

 middlings ration have been 110.9 lbs. and 4.88 lbs. Grinding the corn, accord- 

 ing to the author, effected a saving of 5.7 per cent. The advisability of grind- 

 ing is determined by the price of corn and the cost of grinding. 



" When corn is worth only 25 cts. per bushel the saving from grinding 

 amounts to only 1.4 cts., not enough to pay for the grinding unless cheap power 

 is available. As corn advances in price it will be noticed that the saving per 

 bushel increases practically three-tenths of a cent with each 5 cts. advance in 

 the price of corn. Should the price of corn be as high as 75 cts. per bushel the 

 saving by grinding would amount to a little over 4 cts. per bushel." 



Soy beans v. Tvheat middlings as a supplement to corn meal for gro'wring 

 and fattening pigs, G. C. Humphrey (Wisconsin Sta. Itpt. 1905, pp. 21-30, pi. 

 1, figs. 2). — In continuing the work of the previous year (E. S. R., 16, p. 809), 

 5 pigs were fetT corn meal and soy-bean meal 2 : 1, while a similar lot was fed 

 corn meal and wheat middlings in the same proportion, both lots being given 

 some skim milk. 



During the 27 weeks of the test the average gain per head on the soy bean 

 meal ration was 1.37 lbs. and on the wheat middlings ration 1.24 lbs., the grain 

 consumed per pound of gain in the 2 cases being 3.75 and 4.14 lbs., and the skim 

 milk 3.9 and 4.31 lbs. As shown by slaughter tests with 2 animals from each 

 lot, the dressed weight on soy beans was 82.85 per cent of the live weight and 

 on wheat middlings 84 per cent. Other data are recorded. 



The conclusions drawn from the tests were in effect as follows : Soy beans 

 make an excellent supplement to corn meal for growing and fattening pigs 

 and are a little over 10 per cent more valuable than wheat middlings for pork 

 production. In feeding equal amounts of the two rations, the soy beans and 

 corn meal supply a slightly higher percentage of dry matter and digestible 

 matter than the wheat middlings and corn meal. For firmness, fine grain and 

 texture of flesh, and even distribution of fat and lean, the ration of wheat mid- 

 dlings and corn meal is superior to that of soy beans and corn meal. 



Feeding cotton-seed meal to swine, J. G. Fuller (Wisconsin Sta. Rpt. 

 1905, pp. 31-36). — In the first trial reported a ration of equal parts of corn meal 

 and cotton-seed meal mixed to a thick slop was fed to a lot of 5 pigs, while a 

 similar lot was fed the same mixture soaked in water for 48 hours so that it 

 had become thoroughly soured. 



At first the gains were satisfactory, but about the middle of the 10 weeks' 

 test the pigs began to lose their appetite and for the last 4 weeks they lost flesh 

 and 2 in each lot died late in the test or after it closed. The total gain on the 

 fresh cotton-seed ration was 131 lbs. and on the sour cotton-seed ration 1.39 lbs. 



In a second test, made under practically the same conditions and covering 6 

 weeks, the total gain made by 5 pigs was 41 lbs. on fresh cotton-seed meal and 

 39 lbs. on sour cotton-seed meal. In this test also the gains were satisfactory
