meal. Average daily gains for the four ages of 1.55, 1.88, 2.11, and 1.57 lbs. were 

 obtained, consuming 7.81, 10.75, 10.8, and 14.16 lbs. of feed per pound of gain, 

 and dressing 59.92, 59.49, 58.4, and 58.87 per cent for the respective lots. These 

 results agree in general with those of previous work (B. S. R., 32 p. 467) in 

 which alfalfa hay was fed. It was found, however, that the percentages of 

 dressed beef yielded by the different lots of steers in the alfalfa and milo- 

 maize series were, on the whole, appreciably higher than the corresponding 

 figures in the alfalfa-hay series. 



Preliminary results of experiments in hog feeding at the college of agri- 

 cultui'e, S. B. Durham (Philipinne Agr. and Forester, 4 (1015), No. 8, pp. 173- 

 178). — Hog feeding experiments conducted at the Philippine College of Agricul- 

 ture are reported. On a combination of rice bran and pasture the pigs made 

 average daily gains for 85 days of 0.521 lb. per head. 



Feeding wheat to fattening swine, L. A. Weaver (Missouri Sta. Bui. 136 

 (1915), pp. 3-35, figs. 8). — In two experiments six lots of 6 and 12 hogs each 

 were fed during two periods of 78 and 42 days, or a total of 120 days, with the 

 following results : 



Summary of average results in two swine-fattening experiments. 



Complete data are given on the dressing percentage, weight of blood, liver, 

 entrail fat, heart, tongue, head, shoulder, side, ham, leaf fat, and lard for 

 representative hogs from the several lots. 



Results from similar tests at other stations are included. 



Determination of the race of swine by the protein differentiation method, 

 A. LtJHNiNG (Landw. Jahrb., 47 (1914), No. 3, pp. 443-4^5, figs. 6).— By the 

 protein differentiation method it was found possible to distinguish between the 

 Sus vittatus, S. serofa, and various other species of wild and domestic swine. 



Feeding experiments with sugar and meat meal for horses, L. Greve 

 (Berlin. Ticrdrztl. Wclmschr., 31 (1015), No. 26, pp. 301-303).— It was demon- 

 strated that as much as 6 kg. of raw sugar and 900 gm. of meat meal, daily, 

 may be fed to horses without harmful results. When fed in moderate amounts 

 as a supplement to an oat and hay ration, work horses did well and increased 

 in weight. 



[Poultry husbandry studies], P. Moore (Idaho Sta. Bui. 84 (1915), pp. 28, 

 29). — ^Three pens of 30 White Leghorn pullets each were fed the following 

 rations for one year : Pen 1, a grain ration of wheat, oats, and barley 15 : 2 : 2, 

 and all the grit they would eat ; pen 2, a grain ration of wheat, peas, oats, barley, 

 Kafir corn, millet, sunflower seed, and buckwheat 12 : 2 : 3 : 2 : 1 :1.5 : 0.5 : 1, 

 and a mash ration of bran, shorts, corn meal, wheat meal, fish meat meal, and 

 charcoal 2:2:1:1:2:1 per cent ; and pen 3, a ration the same as that given
