294 EXPERIMENT STATION RECORD. 



From this and the earlier experiments the conclusion was drawn thai "although 



calves Eed for a long period <>n whole milt will show a high rate of increase when 



compared with the gain in weight made by animals reared on other foods, the 

 increase is not proportional to the cost incurred. It is much more economical to use 

 a cream substitute, such as linseed cake, with cod-liver oil, Indian meal, or a mixture 

 of meals, along with separated milk than to use whole milk and linseed cake." 



New experiments on the feeding 1 of calves, A. GouiN and I'. Andouam) 

 ( r,ul. Sta. Agron. Loire-Infirieure, 1902 8, pp. 66-100). — In continuation of work pre- 

 viously reported (E. S. K., II, p. L105), the author studied the water content of 

 flesh, and the effect of acid potassium phosphate, dried calcium phosphate (the 

 natural mineral), powdered green bone, arsenite of potash, hydrochloric acid, and 

 bicarbonate of soda upon the assimilation of food, the metabolism of nitrogen, 

 and the gains made by calves. 



His previous deduction as to the value of powdered hone in inducing gains was 

 continued. The conclusion was reached that calves require smaller amounts than 

 the Wolff standard calls for; for instance, during98 days one of the calves consumed 

 1,947 gm. of dry matter and digested 1,245 gm., the gain made amounting to 852 gm., 

 as compared with 1,740 gm. digestible nutrients, and 550 gm. gain, called for by the 

 German standards. 



Depreciation of leather by brands, J. Mehmken (Breeder's Caz.,46 (1904), No. 

 4, p. ISO, dgm. 1) . — The author discusses the effect of branding upon the value of the 

 dressed hide and points out that the least injury results when branding is done on 

 the jaw. The most damage is caused by the side brand, the hip brand being regarded 

 as between the two in this respect. 



The sheep industry of the Laramie Plains, F. S. King (Ranchman's 

 Reminder, I {1904), No. 7, pp. 83-87, figs. 4). — The early history of the local sheep 

 industry is briefly spoken of. 



Sheep, R. Robertson ( Canada Expt. Farms Rpts. 1903, p. 295). — Brief notes are 

 given regarding the Maritime Provinces Farm flock. 



Swine, R. Robertson, S. A. Bedford, and A. Mackay (Canada Expt. Farms Rpts. 

 1903, pp. 294, 295, 336, 337, 394).— In continuation of tests previously reported 

 (E. S. R. , 15, p. 174) the relative merits of pasturing pigs and feeding in pens was 

 tested at the Maritime Provinces Farm with 2 lots of 10 animals each. The lot 

 pastured for 4 months and then fed in a pen for 1 month made an average daily gain 

 of 1.06 lbs. per head, at a cost of 3.04 cts. per pound, as compared with 0.8 lb. and 

 4.05 cts. in the case of the lot fed in the pens for the entire period. 



At the Manitoba Experimental Farm 4 pigs fed spelt gained 389 lbs. as compared 

 with 407 lbs. in the case of a similar lot fed mixed grain, the calculated profit in the 

 two cases being $8.99 and $9.75. "The pen of animals fed on mixed grain consumed 

 25 lbs. more grain during the fattening period than those fed on spelt." 



In addition to the feeding tests brief notes are given regarding the swine kept at 

 the Maritime Provinces, Manitoba, and Indian Head experimental farms. 



Millet for fattening swine, J. W. Wilson and H. G. Skinner (South Dakota 

 Sta. Bid. S3, pj). 15, figs. 5). — Using 3 lots of 2 pigs each the relative value of ground 

 barley, hog millet (Panicum miliaceum), and wheat was studied. These grains were 

 mixed with water and fed ad libitum. In the 84 days of the test the average daily 

 gain per head on barley was 1.25 lbs., the feed eaten per pound of gain being 4.95 

 lbs. Similar values for millet were 1.13 lbs. and 5.95 lbs., and for wheat 1.67 lbs. 

 and 4.87 lbs. It was noticed that the lot receiving millet relished their feed and 

 were in apparently as good physical condition during the whole test as the other lots. 



Considering the test as a whole the authors calculate that the barley and millet 

 each returned 41 cts. and the wheat 52 cts. per bushel. An examination of similar 

 cuts from the dressed carcasses showed that the percentage of fat to lean in the mil-
