teeth, and a drawn or liuruped attitude when standing. After having been 

 starved or stunted for a period this animal was apparently able to overcome 

 the effects, which suggests that an animal has the capacity to increase its rate 

 of gain for a short period of time, at least, in order to compensate for a low 

 rate at some previous period." 



[Feeding preserved milk to calves], U. A. Brown (Michigan Sta. Rpt. VJlIi, 

 pp. 206-210). — In trials to determine the advisability of using formaldehyde 

 as a preservative for skim milk fed to 4 to 7-week-old calves for 24 weeks, 7i 

 cc. of 40 per cent formaldehyde being used to each 100 lbs. of milk, it was found 

 that in general the calves suffered no deleterious effects from the preservative, 

 and as compared with calves fed sweet milk or sour milk, made slightly greater 

 gains at somewhat lower cost. From records kept of the after development 

 of these calves it was found that those which had been fed the preserved 

 milk continued to make the cheapest gains, followed by the sweet milk fed calves 

 and the sour milk fed calves. 



For the entire experiment the calves fed sweet milk made a total gain of 

 1.997 lbs., costing 5.41 cts. per pound; those fed sour milk 2,489.4 lbs., costing 

 r>.43 cts. per pound; and those fed the preserved milk 2,5o7 lbs., costing 5.23 

 cts. per pound. 



It is concluded, however, that the work should be carried on with a large 

 number of calves before definite conclusions can be drawn. 



The characteristics of the hybrid zebu, C. Pucci (Agr. Colon. [Italy], 8 

 (1914), No. 10, pp. 613-619), pis. 3). — Experiments are reported in crossing the 

 zebu on various Italian and European breeds of cattle. The hybrid showed 

 greater resistance to disease, earlier maturing qualities, and more marked beef 

 qualities. 



Rations for breeding ewes, H. Hackedobn (Missouri Sta. Bui. 120 (1914), 

 pp. 31-57. figs. 9). — Lots of 2 to 4-year-old Colorado ewes, weighing approxi- 

 mately 86 lbs., were fed during the winter season with the results shown in the 

 following table :
