ANIMAL PRODUCTION. 871 



live-stock industry of Sao Paulo. Methods of feeding, breeding, and manage- 

 ment are described, and a list of the principal forage plants and their yields 

 per acre is also given. 



I/ive-stock industry [of southern India], J. de Olivares (Daily Cons, and 

 Trade RiJts. [U. S.], Jo {1912), No. 24I, pp. 211, 2i2).— This contains some sta- 

 tistics on the rapid development of the live-stock industry in southern India. 

 This is attributed to various causes, chief of which are the greatly increased 

 feeding resources resulting from extensive irrigation and the successful work 

 of veterinarians in checking diseases to which cattle are subject. 



Managing and equipping a two-hundred-acre stock farm, M. P. Jabnagin 

 (Tenn. Agr., 1 {1912), No. Jf, pp. 147-161, figs. 10).— A system of live-stock 

 farming is outlined, which includes data as to the amount of feed required for 

 farm animals, the rotation of crops, and other points relating to the successful 

 management of a live-stock farm. 



Our knowledge of the carbohydrates in the economy of the animal, R. 

 Lepink {Rev. Gen. ScL, 23 {1912), No. 12, pp. //63-.'/6S).— This is a historical 

 rgsume of the growth of the knowledge on carbohydrate metabolism. 



The effect of sugar on metabolism, A. Gouin and R. Andouard {Compt. 

 Rend. Sac. Biol. [Paris], 72 {1912), No. 26, pp. 113-115).— An experiment with 

 a IJ-year-old heifer, which lasted for 7 weeks. During the whole period the 

 dailj' ration consisted of SOO gm. of peanut cake and hay ad libitum, and, in 

 addition, during the first 3 weeks, potatoes ; during the next 2 weeks one-half 

 of the potatoes was replaced with carob beans; and during the last 2 weeks 

 carob beans equal in nutrients to the potatoes fed at first. During the second 

 period the potatoes and carob beans furnished 128 gm. saccharose daily, and 

 during the third period the carob beans furnished 218 gm. saccharose daily. 



There was a great reduction in the secretion of urine and urinary nitrogen 

 and in general in the percentage of nutrients digested on addition of saccharose 

 to the rations. The daily increase in weight was for the first period 501 gm., 

 for the second period 1,000 gm., and for the third period 857 gm. The experi- 

 ment will be repeated with a younger animal.
