DAIRY FARMING— DAIRYING— AGROTECHNY. 



Beport of the animal industrialist, J. M. Scott ( Florida Htn. Rpt. 1908, 

 pp. XVII-XXIIl). — Two feeding tests were made with dairy cows. In the 

 first test cotton-seed meal was contrasted with coconut meal as a supple- 

 ment to a basal ration of wheat bran and shorts. The results of three feeding 

 periods of 21 days each are sunnnarize<l. and show that 252 lbs. of cotton-seed 

 meal, fed with bran and shorts, produced 1,SSS.5 lbs. of milk, while 453 lbs. 

 of coctnnit meal, fed with bran and shorts, produced 1,844 lbs. of milk. " The 

 conclusion that we may draw from this test is that 1 lb. of cotton-seed meal 

 is nearly tniual to 2 lbs. of coconut meal for milk production." 



In the second test sorghum silage and sweet potatoes were contrasted as 

 tjupplementary feeds, the basal ration consisting of cotton-seed meal and wheat 

 bran. " The results were that 4,819.5 lbs. of sweet potatoes produced 3,122.25 

 lbs. of milk, while 6,898.5 lbs, of sorghum silage gave 2,800.25 lbs. of milk. In 

 other words, 100 lbs. of sweet potatoes with cotton-seed meal and wheat bran 

 produced approximately 65 lbs. of milk, while 143 lbs. of silage with the same 

 amount of cotton-seed meal and wheat bran i)roduced about 58 lbs." 



Experiments with dairy cows, G. E. Day (Ann. Rpt. Ontario Agr. Vol. and 

 E.rpt. Farm, S'l (/.90.S). ]>p. 13S-l.'i2, fig. J). — Herd records are reported, to- 

 gether with feeding trials in which oats and bran were contrasted witli 

 Schumacher and Molac dairy feeds. 



The average yields of milk per day per cow were as follows : In the first 

 experiment with oats and bran, 25.71 lbs. of milk containing 3.85 per cent 

 fat, and with oats and Molac, 25.57 lbs. of milk containing 3.76 per cent fat; 

 in a second experiment, oats and bran, 35.45 lbs. of milk containing 3.68 per 

 cent fat, and with bran and Schumacher feed, 33.43 lbs. of milk containing 

 3.45 per cent fat; in a third experiment, bran and oats, 26.83 lbs. of milk 

 containing o.OS per cent fat, and with Molac and Schumacher feeds, 27.93 lbs. 

 of milk containing 3.74 per cent fat. 



" The amount of Molac fed in the first experiment was less than the amount 

 of bran, and the Schumacher fed in the second experiment was less than the 

 amount of oats. It might have been more satisfactory had the amomits been 

 equal in each case, but the i-eduction was made because it is claimed that 

 Molac contains more nutriment than bran, and that Schumacher contains 

 mor<' iiutrinieut than oats, and an attemiit was made to equalize the rations." 



The grape as a feed for dairy cows, G. Fascetti and N. Fotticchia (Agr. 

 Mod., 1.1 { 190!)), A'o.s-. JS, pp. 110-112; 1',, pp. 188-190; 16, pp. 2i2-2/.'/).— Grapes 

 were mixed with a ration of bran, maize cake, meadow hay, and alfalfa and 

 foinid to he palatable and nutritious. They were estimated to be worth about 

 4 lira per quintal (about 35 cts. per 100 lbs.) as a dairy feed, which is some- 

 what higher than would be expected from a chemical analysis, which was as 

 follows: I'rotein, 0.862; fat, 0.30G ; nitrogen-free extract, 16.711 per cent. 



Importance of the dairy industry for the Latin- American countries {lioJ. 

 Min. Agr. [Buenos Aires], 10 (1908), No. 3, pp. 2,'/0-„^6*2).— Statistics are pre- 

 sented as a basis for showing the importance of making more progress in the 

 dairy industry in South American countries. 



Pure milk and the public health, A. 11. AVard and M. E. Jaffa (Ithaea, 

 N. Y., 1909, pp. XIII -f 218, figs. 11). — This is a manual for the milk and dairy 

 inspector, in which are assembled facts needed by the health officer and others 

 directly concerned in the crusade for better milk. The principal topics treated 

 are equipment of a sanitary dairy plant, proper methods of handling milk, the 

 changes in milk caused by bacteria, epidemic diseases transmitted by milk,
