74 EXPERIMENT STATION RECORD. 



pound. During the remainder of tlie 90-day period 4 of the steers received cold- 

 pressed cotton-seed calce and Johnson grass hay, and made a gain of 1.25 lbs. 

 per head and day, while the other 4 steers on cotton-seed meal and hulls gained 

 O.S.'j lb. pev head and day. 



Another lot of S steers on cotton-seed meal and Kafir corn forage for 34 days, 

 and then on cotton-seed meal, rough red rice, and cotton-seed hulls for 56 days, 

 made an average daily gain of 2.7 lbs. at a cost of 9.16 cts. per pound. A lot on 

 cotton-seed meal, rough red rice, and Johnson grass hay during the entire 90 

 days gained 2.19 lbs. per head and day, at a cost of 12.29 cts. per pound. A 

 ration of cotton-seed meal and hulls for 90 days produced an average daily gain 

 per head of 2.44 lbs., at an average cost of 8.72 cts. per pound. 



Block tests shov^-ed that the last lots were superior to the others ia quality of 

 meat, although the percentage of dressed weight was less. Though Kafir corn 

 forage proved uupi'ofitable, it is thought to be an economical feed if fed with the 

 heads ground and the stalks shredded. When the price of Johnson grass hay is 

 reasonably low it is recommended as a roughage for fattening steers, but none 

 of the feeds at the prices estimated in the bulletin can economically take the 

 place of cotton-seed meal and hulls. 



The pig feeding tests were made with grade Poland-Chinas, Duroc Jerseys, 

 and Berkshires. There were 5 lots of 10 pigs each, and the average gains per 

 head and day were as follows: On cotton- seed meal and corn chop, mixed and 

 fermented, 1.8 lbs. at a cost of 4.56 cts. per pound ; on cotton-seed meal and 

 uuground rough red rice, mixed and fermented, 1.4 lbs. at a cost of 5.74 cts. per 

 pound; on tankage and unground rough red rice, mixed and fermented during 

 the larger portion of the period, 1.28 lbs. at a cost of 7.6 cts. per pound ; on 

 alfalfa meal and rough red rice (most of the time ground), mixed and fer- 

 mented, 1.26 lbs. at a cost of 8.08 cts. per pound; on alfalfa meal and corn 

 chop, fermented, 1.14 lbs. at a cost of 11.02 cts. per pound. 



These results show that ground rough red rice fed with cotton-seed meal is 

 an economical ration for fattening hogs. The lots receiving most nearly the 

 standard ration made the largest and most economical gains. At no time 

 during the experiments was there any injurious effects from feeding cotton- 

 seed meal. 



Pig feeding experiments and two kinds of hog houses, A. L. Stabler 

 {Marylancl Sta. Bui. 150, pp. 93-132, figs. 11). — This bulletin reports feeding 

 tests with pigs, and describes two styles of hog houses in use at the station. 



The first feeding trial was with 10 Poland-Chinas divided into 2 equal lots. 

 One lot, on a ration of ground corn fodder, in .3 months made an average daily 

 gain of 0.573 lb. at a cost of 6.88 cts. per pound. A lot on corn and cowpea 

 silage ad libitum gained 0.73 lb. per head and day, at a cost of 6.51 cts. per 

 pound. In a comparison of shelled corn and corn meal fed in connection with 

 skim milk somewhat better gains were made than with corn meal alone, but 

 this advantage was offset by the higher cost per pound of gain. 



Comparison was made of wet, soaked, and dry feeds when the ration con- 

 sisted of corn-and-cob meal, wheat middlings, and gluten meal. In a trial 

 lasting 112 days a lot receiving the grain in the form of a thick slop by mixing 

 with water or milk made an average daily gain per head of 0.623 lb., at a cost 

 of 7.82 cts. per poimd. When the feed was mixed and allowed to soak 24 hours 

 before feeding, the gain per head and day was 0.789 lb., at a cost of 6.63 cts. 

 per pound. The lot fed dry grain made an average daily gain per head of 

 0.713 lb., at a cost of 6.87 cts. per pound. 



In another test when chopped alfalfa was added to a ration of shelled corn 

 and wheat middlings, the gains were reduced the first part of the period but 

 increased the latter half. In a feeding test with wheat bran substituted for
