1168 EXPERIMENT STATION EECORD. 



(1907), No. 10-12, pj). Ji97-537, dgin. 1). — From the experimetnal data reported 

 the author comes to the conclusion that when asparagin embodied in zelloidin, is 

 fed to Carnivora (dogs) as a part of a productive ration, the gains in nitrogen 

 are nearly twice as great as when free asparagin is used. Like quantities of 

 nitrogen (1 or 2 gm.), in the form of blood albumin or asparagin inclosed in 

 zelloidin have practically the same value as regards gains in nitrogen, provided 

 the deficiency in energy value of the asparagin is made good. In the author's 

 opinion the physiological equivalent of asparagin and protein is not established 

 and the ultimate effects must be taken into account. He believes that the 

 unsatisfactory results obtained by earlier experimenters with asparagin and 

 amids in general are due to the fact that they have been mixed directly with 

 the ration. Other earlier work has been noted (E. S. R., 19, p. 109).

Additional feeding tests comparing dried beet tops, dried beet chips, sour 

 beet tops, and meadow hay, W. Schneidewind and D. Meyer {UIus. Landiv. 

 Ztg., 27 (1907), Nos. 60, pp. 529, 530; 61, pp. 537, 538).— Although smaller quan- 

 tities of dried beet leaves were fed in tests with sheep and steers than was the 

 case in earlier tests (E. S. R., 19, p. 67), the same conclusion was reached, 

 namely, that dried beet leaves do not have greater nutritive value than meadow 

 hay of medium quality. 



Farm live stock of Great Britain, R. Wallace (Edinhurfjh and London, 

 1907, 4. ed., i)p. ZA'A'/+7.58, pis. 21.'f, figs. 66').— The author states that this 

 work has been rewritten and more than doubled in size. In the revision 

 special attention has been paid to the history of various breeds of cattle and 

 references have been made to sources of information. The subject of " home " 

 or " first-aid " of farm animals has been exhaustively dealt with. The volume 

 as a whole constitutes a handbook of information on cattle, horses, sheep, and 

 farm animals in general. 



Number and farm value of farm animals in the United States, 1867-1907 



(U. .S'. Drill. Agr., Bur. Htatis. Bui. 6'/, pp. 5-].'i5). — This bulletin i)resents in 



tabular form statistics of the numl)er, :iverage farm price, and value of horses, 



.mules, milch cows, other cattle, sheep, and swine by States and by years from 



1SG7 to 1907, inclusive. 



Growing cattle in western Nebraska, W. P. Snydek (Nchraska Sta. Bui. 

 105, pp. 23, figs. //). — When 7.5 steers were dehorned and turned on pasture 

 they lost on an average 27 lbs. per head in a month as compared with 19 lbs. 

 per head in the case of similar steers which had not been dehorned. Imme- 

 diately after this the steers were taken to another locality and pastured for 7 

 months. The dehorned steers showed an average gain of 253 lbs. and those 

 not dehorned 2GG lbs. Considering, however, that dehorned steers sell for a 

 higher price for feeding purposes, the author calculates that the dehorned lot 

 was the more profitable. 



Mixtures of alfalfa hay and prairie hay and of alfalfa hay and cane hay 1 : 1 

 were compared with each of these hays alone, using 5 lots of 20 calves each. h. 

 ration of 2 lbs. of corn and oats per head per day was fed in addition to the 

 hay. The daily gain in 116 days ranged from 0.39 lb. per head on cane to 1.23 

 lbs. on alfalfa but was almost as great on the mixed hay rations as on the 

 alfalfa alone, being 1.14 lbs. on alfalfa and prairie hay and 1.20 lbs. on alfalfa 

 and cane hay. The hay required per pound of gain ranged from 10 lbs. on 

 alfalfa alone to 36.66 lbs. on cane alone and the greatest range in grain was 

 also noted with these two lots, being 1.62 and 5.04 lbs., respectively. The gain 

 was most cheaply made on alfalfa, costing 2.82 cts. per pound and was most 

 expensive ou cane hay, costing 7.83 cts. per pound.
