ANIMAL PRODUCTION. 671 



The general conclusions of these experiments are as follows : " Clover proved 

 to be the most profitable single forage crop for pork production. Next to 

 clover, rape and oats produced the largest number of pounds of pork per 

 acre. Corn has been successfully and profitably utilized by permitting the 

 hogs to harvest the crop. In general it may be said that under existing con- 

 ditions the cost of producing pork may be greatly reduced by making a larger 

 use of forage crops. A good system of forage crop rotations for Missouri is a 

 3-year rotation of rape, clover, and corn in conjunction with permanent blue 

 grass pasture." 



Report on pig' feeding experiments, B. N. Wale (Seale-Hayne Agr. Col. 

 [Puh. 1], 1913, pp. 16). — Results of experiments carried out during the last 3 

 years to compare the value of various feeds for pork and bacon production are 

 reported. 



A comparison of the feeding value of English and Russian barley gave the 

 latter the preference both as to yields and financial returns. In an experi- 

 ment where soy-bean cake replaced barley, "it was found that a much gi-eater 

 profit was realized where no soy-bean cake was fed, and that soy-bean cake 

 in small quantities did not form a profitable feed for bacon production." 



In an experiment testing the value of fish meal for pig feeding, 1 lot of pigs 

 fed approximately 2 lbs. of fish meal and 7 lbs. of gram and maize for 4 

 mouths, made about 21 lbs. per pig greater gain than another lot fed on gram 

 and maize alone. In another case a lot of pigs receiving about 1 lb. of fish 

 meal and 7 lbs. maize during a 4 months' feeding period made 34 lbs. per pig 

 greater gain than a lot fed on maize alone. In both instances financial returns 

 favored the pigs fed on fish meal. 



Swine-feeding' experiments with hominy feed in comparison with barley. 

 Institute at Proskau, 1912, Klein (Mitt. Ver. Deut. Schweineziichter, 20 

 (1913), No. 7, pp. 143-145). — In experiments with 6-weeks-old pigs for a 

 period of 12 weeks lot 1, receiving per head an average daily ration of 2.5 kg. 

 milk and 0.6 kg. barley made a total gain of 205 kg. at a cost of 0.53 mark (5.73 

 cts. per pound) per kg. Lot 2, receiving 2.5 kg. milk, 0.24 kg. barley and 

 0.36 kg. hominy, made a total gain of 212.25 kg., costing 0.49 mark per kilo- 

 gram. Analyses of these feeds showed the hominy to be somewhat higher in 

 crude protein and ash than the barley. 



Fattening of pigs with, the automatic feeder, De la Baeee (A 6s. in Internat. 

 Inst. Agr. [liome^. Mo. Bui. Agr. Intel, and Plant Diseases, 4 (1913), No. 6, 

 pp. 932, 933). — Four 6-weeks-old pigs were fed crushed barley, wheat meal, and 

 fish meal freed from fat 2:1: 0.2, in addition to an allowance of separated 

 milk for the first four weeks and of mangels and green feed thereafter, and 

 when 26 weeks old had made a total gain of 754.6 lbs., costing £1 Ss. 5d. ($6.91) 

 per 100 lbs. gain. 



Action of iron-containing blood meals on iron assimilation in animals, 

 J. Gk6h (Biochem. Ztschr., 53 (1913), No. 3, pp. 256-.258).— Experiments with 

 swine indicated that the feeding of iron-containing blood meal did not ma- 

 terially increase the iron content of the body over that of animals not so fed. 



The regular irregularities of the pulse of the horse, L. Stegemann (Die 

 Reguldre Irregularitdt des Pulses beim Pferde. Inaug. Diss., Tierarztl. Hochsch. 

 Hannover, 1912; ahs. in Deut. Tierarztl. Wchnschr., 21 (1913), No. 26, p. 421). — 

 The author calls attention to the periodic irregularities of the pulse of the 

 horse and explains the causes for this apparent phenomenon. 



On the process of stomach digestion of the normally fed and watered 

 horse, A. Scheunert and A. Schattke (Ztschr. Tiermed., 17 (1913), Nos. 5, 

 pp. 177-264, figs. 2; 6, pp. 225-245, figs. 18; 7, pp. 273-302) .—This is a technical
