Three lots of 2 cows each, equal in milk yield, period of lactation, etc.. were 

 maintained for 20 weeks on the respective plats and data kept on their produc- 

 tion. Yearlings were added as the plats needed heavier pasturing and removed 

 during light pasture. Data were collected on increase in weights, etc. 



The total milk production for the two years' trials was for plat 1, 1,510 gal., 

 plat 2, 1,489 gal., and plat 3, 1,168 gal. The total value of products, including 

 milk and grazing, was £43 ]3s. Id., f43 14s., and £31 16s. lid. for the resi^ective 

 plats, while the net value per acre after deducting the cost of manures for plats 

 1 and 2 was £11 13s. lOd., £11 2s. 9d., and £9 Is. 9d., respectively. 



reeding of cattle on phosphatic pasture, C. Seltenspergee (Vic Agr. ct 

 Rurale, 2 (1913), No. 48, pp. 569, 510; ahs. in Indus. Lait. [P-aris], 39 {191^), 

 No. 5, p. 91). — The author records his observations in the feeding of cattle on 

 phosphate-fertilized pastures. He concludes that such fertilizing favors the 

 growth of the legumes and other flora rich in phosphorus content, that the 

 phosphorus is more easily assimilated by the animal body in this form than 

 when fed as bone meal and mineral phosphates, and that in turn the phosphorus 

 content of the milk products is correspondingly increased. 



Dairy herd records for fourteen years, J. H. Frandsen and A. L. Haecker 

 (Nebraska Sta. Bui. 139 (1914), pp. 3-30). — In summarizing the herd records 

 for the past 14 years at the Nebraska Station it is shown that the average 

 production per cow was 7,020.8 lbs. milk and 341.71 lbs. of butter, which yield is 

 nearly three times the amount produced by the average dairy cow of the State, 

 and indicates the great Increase that may be attained by proper breeding and 

 feeding. The rations were made of Nebraska-grown crops and feeds, and the 

 I)rincipal roughage was corn silage and alfalfa hay. The herd from a financial 

 standpoint yielded a handsome profit during all the years of the test. 



In studying the individual records it is noted that a large flow of milk is 

 generally accompanied with a low milk fat test, while a small flow has a high 

 milk fat test. 



A new Holstein record (Kimiairs Dairy Farmer, 12 (1914), ^o. 6, p. 163, 

 figs. 2). — ^An account of a Holstein cow which at 3^ years produced 30.1 lbs. 

 butter from 588.6 lbs. milk in 7 days; 123.88 lbs. butter from 2,522.2 lbs. milk 

 in 30 days; at 4i years 32.72 lbs. butter from 613.3 lbs. milk in 7 days; 135.31 

 lbs. butter from 2.632 lbs. milk in 30 days; at 5* years 35.43 lbs. butter from 

 750 lbs. milk in 7 days; and 144.64 lbs. butter from 3,090.06 lbs. milk in 30 days. 



It is stated that while these figures have not been officially authorized they 

 are essentially correct. 



Nourishment of young animals with self and foreign milk, W. Schrape 

 {Expe7-'hnentcUe Beitrdge zur Erndhrung iicnscher Sduglingc mit arteigener 

 und artfremder Mileh. Inaug. Diss., Univ. Leipsic, 1912, pp. 82). — In trials with 

 lambs, young rabbits, and guinea pigs it was found that the value of the 

 mother's milk is greater than of foreign milk, that mother's milk in the raw 

 state is as healthful as the cooked, and that in the feeding of foreign milk to 

 young animals it is advisable to heat the milk. 



There are aiipended 87 references to works on milk feeding and milk hygiene. 



The etiology of epidemic septic sore throat (Jour. Anier. Med. Assoe., 62 

 (1914), No. 11, p. 853). — Evidence is presented to show that "the cause of the 

 infection in septic sore throat is the streptococcus which is discharged from 

 the inflamed udder of the dairy cow into the milk, through which it is trans- 

 ferred to the throats of milk consumers." Animals suffering from garget are 

 thought to be a frequent source of infection in man. It is pointed out, however, 

 " tha.t in addition to the jirimary infection of milk, pathogenic organisms may 

 be accidentally introduced into it through its being handled by persons suffer- 

 ing from streptococcic infection."
