ANIMAL PRODUCTION. 1115 



pastured on one-third of an acre planted to peas and oats, 7 pigs gained 70 lbs. in 27 

 days, or at the rate of 210 lbs. of pork per acre. 



In a second test the gain was at tbe rate of 166.5 lbs. per acre. When pastured on 

 a plat planted to sugar beets and fed some grain in addition L6 pigs gained 584 lbs. in 

 40 days, the estimated gain on the beets only being at the rate of 715.5 lbs. per acre. 

 In a similar test on a plat planted to sugar beets and mangel-wurzels the gain due to 

 roots was calculated to be 792 lbs. per acre. 



As pointed out by the author, pasturage for brood sows during the growing season 

 is generally regarded as very desirable and the value of June grass and rape for tins 

 purpose was tested with 5 dry sows. No supplementary feed of any sort was sup- 

 plied. Some of the animals gained a little and others lost, but on an average there 

 was an increase of 2 lbs. in weight. 



Tankage and other by-products for pigs. Shrunken wheat for swine, 

 J. W. Wilson and H. G. Skixxek (South Dakota Sta. Bid. 90, ji/>. L.'). — Using 7 lots 

 of 6 pigs each the relative feeding value of tankage, blood meal, linseed meal, ground 

 flax, and skim milk, fed in addition to ground barley and one-fourth acre rape pas- 

 turage, were tested in comparison with a ration of barley alone. 



During the whole test, which covered 84 days, the average gain on barley was 

 102 lbs., 5.77 lbs. of feed being required per pound of gain at a cost of 3.91 cts. On 

 the other rations the gain ranged from 109 lbs. on barley and rape to 151 lbs. on 

 barley, skim milk, and rape. The greatest range in the cost of a pound of gain, 

 3.92 cts. to 4.51 cts., was also noted with these 2 lots. The smallest amount of feed 

 per pound of gain, 4.62 lbs., was noted with the lot fed oil meal, and the largest 

 quantity, 15.34 lbs., with the lot fed barley and skim milk. 



In discussing the feeding value of rape attention is called to the fact that the lot 

 on barley and rape gained 46 lbs. more than the lot fed barley only, the amount of ' 

 grain consumed being practically the same in the 2 cases. 



During the past season a considerable amount of wheat in the northwestern 

 United States was more or less damaged by rust and its value lessened for milling 

 purposes. The feeding value of 2 lots of this shrunken wheat, weighing respec- 

 tively 57 and 44 lbs. per bushel, was studied. During the 112 days of the test 2 pigs 

 fed the heavier wheat made an average daily gain of 2.3 lbs. per head, as compared 

 with 2 lbs. on the lighter wheat, the grain required per pound of gain in the 2 cases 

 being 3.8 and 4.2 lbs., respectively. Rating pork at 4 cts. per pound, the heavier 

 wheat was calculated to have a value of 63 cts. per bushel and the lighter 57 cts. 

 Analyses of the 2 sorts of wheat are reported. 



Grain rations for dry-lot hog feeding, E. B. Forbes (Missouri Sta. lint. <;:>, />/>. 

 29-92). — Various questions connected with pig feeding are considered, special interest 

 attaching to the discussions of the importance of palatability, the adaptability of 

 digestive secretions, stimulation of the digestive organs, and related questions not 

 commonly considered in animal feeding though of recognized importance in human 

 nutrition. 



The object of the tests reported was to compare linseed meal, wheat middlings or 

 ship stuff, wheat bran, and oats in different proportions, bone meal, and gluten feed 

 as supplements to corn, and to learn the relative merits of soaked corn, corn meal, 

 corn-and-cob meal, and whole corn for dry-lot pig feeding. 



The tests Avere made with 19 lots of 5 to 10 pigs each and covered periods of 60 to 

 90 days, Nos. 1 to 12 being made in the spring, Nos. 13 to 17 in midsummer, and Nos. 

 18 and 19 in the autumn. In the tests made in the spring, which were carried on 

 under uniform conditions, the greatest gain, 1.48 lbs. per head per day, was made 

 on a ration of corn meal and linseed-oil meal 5: 1, and the smallest gain, 0.32 lb. per 

 head per day, on corn-and-cob meal. 



In the tests made in the summer and autumn the average daily gain ranged from 

 1.133 lbs. per head on corn meal and wheat middlings 4: 1 to 1.624 lbs. per head on
