until the sixth week, when 1 pig fed the fermented cotton seed dicil .md Ihc con- 

 dition of the remainder was such that the experiment had to l)e discontinued. 

 Two pigs died a few days afterwards. In this and the preceding test post 

 mortem exannnation sliowed that the vital organs were affected, as has been 

 noted in other exju'riments with cotton-seed meal. 



In the third trial, which was made with 2 lots of 7 pigs each, the ration con- 

 sisted of nine-tenths corn meal and one-tenth cotton-seed meal fed in compari- 

 son with corn meal and wheat middlings 1 : 1, the grain in both cases being sup- 

 plemented by skim milk. In 9 weeks the pigs fed cotton-seed meal gained ?m2 

 lbs. and those fed wheat middlings 409 lbs. In the fifth week of the test one 

 of the pigs fed cotton-seed meal died, but post-mortem examination showed none 

 of the conditions present in the other trials. 



" From these trials there is no encouragement for the faruKU', under our 

 present knowledge, to feed cotton-seed meal to swine. While it is used (juite 

 generally for dairy cows, and, in certain localities, is fed in large quantities to 

 fattening cattle, it may prove fatal to swine when fed even in relatively small 

 quantities." 



Middlings and ground barley v. niiddlings and corn meal as a grain 

 ration for young sows, J. G. Fuller (Wisconxin Sta. Rpt. 1905, pp. ,31', 38). — 

 Six young sows fed ecpial parts of wheat middlings and ground barley mixed 

 with skim milk made a total gain of 043 lbs. in 15 weeks, the total amount of 

 grain and skim milk eaten being 3,370 and 4,008 lbs., respectively. An etiual 

 mnnber of sows fed wheat middlings and corn meal 1 : 1 with skim milk gained 

 7;;0 lbs. and consumed a total of 3,342 lbs. of grain and 4,008 lbs. of milk. 



The inferior gain made on the ground-barlej^ ration was attributed to the 

 fact that one of the pigs lost weight rapidly toward the close of the test. 

 With this exception the animals in both lots were in excellent condition at the 

 close of the trial. 



The location, construction, and operation of hog houses, W. Dietrich 

 (flliiiois 8ta. Bui. 109, pp. 2S6-302, figs. G). — The location and construction of 

 hog houses are discussed and mehtods of operating a hog house planned and 

 built at the station, which meets the requirements indicated, are given. 



According to the author's summary — 



"A hog house should be located so that it is well drained, well lighted, and 

 gives access to pasture, good shade, pure running water, and clean mud wallows. 



" The two princii)al kinds of hog houses are the individual houses and the 

 large houses with individual pens. Each has its points of advantage. 



" For sanitation the building should be constructed so that it is dry, venti- 

 lated, free from dust and drafts and so that the direct rays of the sun fall upon 

 the floor of the p(>ns at the time the winter crop of pigs is farrowed. These 

 rays should also be excluded during the summer. 



"The building should be made serviceable by luMug built so that it can be 

 used every day in the year and be arranged so that the largest amount of work 

 may be performed with the smallest amount of labor. 



" For large houses gates and partitions made of wire are best because they 

 <]<> not obstruct the light and heat rays from the sun, do not hide the pigs from 

 \ iew of the attendant, nor from each other, and do not furnish lodgment for 

 disease germs. 



"The large hog house is operated so that two litters per year are farrowed 

 and grown for market and so that the pigs are put on thv market at the most 

 favorable season.
