EXPERIMENT STATION RECORD. 



[Vol. 43 



Two studies of sour skim milk in chick rations are in proscress. At the 

 Irerlell substation tlie average chick fed corn meal, oats, soy bean meal, and 

 meat scrap weighed 0.7 lb. at 8 weeks and 2.9 lbs. at 16 weeks, while the 

 chicks fetl the .«;iime mixture plus skim milk, averaged 1.32 lbs. at 8 weeks and 

 3.7 lbs. at 16 weeks. In a similar comparison at the Edgecombe substation 

 the basic feed consisted of com meal and peanut meal. The lot not fed milk 

 averaged 0.87 and 2.07 lbs. at the respective standard ages, and the lot given 

 the skim milk averaged 0.91 and 3.45 lbs. 



The Bergen County international egg-laying and breeding contest, H. R. 

 Lewis (Neio Jersey Sta.s., Hints to PouUrymen, 8 {1920), No. .9, pp. //). — This 

 is an announcement of a 3-year contest at Westwood, Bergen County, N. J., 

 and a statement of the contest rules. 



" The new contest which will start November 1, 1920, will introduce an en- 

 tirely new and distinct feature in poultry work, namely, the registration and 

 advanced registration of poultry, and the maintenance of flock books, which 

 will show pedigrees and performances of all birds qualifying for registration." 



Common sense in poultry keeping, R. R. Slocum (U. S. Dept. Agr. Year- 

 book 1919, pp. 307-317, figs. 17). — The author takes the view that success with 

 farm poultry depends primarily on good judgment, and that elaborate rules and 

 complicated methods are not necessary. 



DAIRY FARMING— DAIRYING. 



Mixed-grass pastures for coavs, D. Hanskn and B. L. Collins (U. S. Dept. 

 Agr., Dept. Circ. 86 (1920), pp. 25-32, fig. 1). — These pages summarize the 

 results during the first year (1918) of a comparative test of three 'different 

 irrigated mixed-grass pastures for dairy cows at the Huntley (Mont.) Reclama- 

 tion Project Experiment Farm. Mixture No. 1 consisted of awnless brome grass, 

 orchard grass, tall fescue, perennial rye grass, Kentucky blue grass, white 

 clover, and alsike clover. No. 2 differed from this by the omission of the 

 clovers, while brome gi'ass and rye grass were omitted from No. 3, in both 

 cases without change in the rate of seeding of the remaining constituents. Two 

 one-acre plats had been seeded to each mixture in 1916, the Kentucky blue grass 

 being seeded in 1917. On May 22, 1918, three Holstein cows were turned on 

 each mixture. They were alternated from one plat to the other during the 

 season, with occasional days off pasture, when the cows were fed alfalfa hay. 

 On June 10 a grade cow (dry) was added to each lot, and beginning August 28 

 the animals were removed at night. The Holstein cows were in different stages 

 of lactation, and of those assigned to mixtures 1 and 3, one cow in each case 

 was dry throughout. Complete milk records were kept, and fat analyses and 

 lactometer readings were made each week. The following table summarizes 

 the results, reduced to an acre basis :
