The results are expressed iu tabular form. During the whole test 

 the 5 Poland-Chinas gained 1,168 lbs. and tlie 5 Berksliires 1,1<)7 lbs. 

 The amount of each sort of food reciuired for 100 lbs. of gain by the 2 

 breeds is shown iu the followiug table : 



Food rci] Hired for 100 Ihs. ffaiti in lire weight. 



Grain (wheat, shorts and corn meal) 

 Cotton-soed meal and linseed meal. 



Skim milk 



Whey 



Practically the same gains were made by each lot. This fact is 

 further shown in discussing the results by substituting for skim milk 

 and whey a calculated equivalent amount of grain. 



Cotton-seed meal and linseed meal as a ]i)artial grain food for pir/s (pp. 

 9-11). — The 2 periods in the above experiments during which cotton- 

 seed meal was fed are discussed in detail. A table is given showing 

 the amount of food consumed by each lot, the average weight at the 

 beginning, and the gain in weight. 



"Giving to wbey and milk their grain equivalent as used in the previous trial, we 

 tind that for 100 lbs. of gain, live weight, it required 492 lbs. of meal or its equiva- 

 lent, with the pigs getting cottou-seed meal, and 516 lbs. of meal or its equivalent, 

 with the pigs getting linseed meal. Our pigs receiving linseed meal therefore ate 

 24 lbs., or 5 per cent, more of feed than did those getting cotton-seed meal. . . . 



No deleterious effects were noticed with our pigs, but it should be remembered that 

 the experiment lasted only 7 weeks and that the quantity of cotton-seed meal fed 

 was very small. It is probable that cotton-seed meal can be fed to pigs successfully 

 as in our case where the (quantity of meal so given is small, not over one-quarter of 

 a pound daily for each hundredweight of animal." 



The relative value of cooked and, iincoolced feed for swine (pp. 11-20). — 

 This work is a continuation of that given iu the Annual Kei)ort of the 

 station for 1886. It includes a brief summary of the work done at the 

 station and elsewhere on this subject. The results are given of 5 tests, 

 in each of which one lot was fed corn meal which had been cooked into 

 a thick mush, another lot corn meal which had been moistened with 

 hot water and fed at the same temi)erature as the mush (100°). In 3 

 tests a third lot was fed a ration of equal parts of cooked and uncooked 

 corn meal. The first test was made with 15 full blood and grade 

 Berkshire pigs, divided into 3 lots of 7 each; the second test was made 

 with 12 Berkshire pigs, divided into 3 lots of 1 each; the third with 

 crossbred Berkshire- Yorkshire pigs, divided into 3 lots of 2 each; 

 the fourth with -I Poland-Chinas and 10 Berkshires, divided into 2 lots 

 of 10 each; and the fifth with 2 crossbred Poland-China-Berkshires 

 and G Poland-Chinas, divided into 2 lots of -t each. In each case a 

 preliujinary period of 1 week ])receded the test.
