1917] DAIRY FARMING DAIRYING. 271 



Feeding for egg production, P. Moore (Idaho Sta. Circ. S (1916), pp. 6). — 

 Results are given of a feeding experiment which began November 1, 1914, and 

 ended October 31, 1915, with three pens of 30 White Leghorn pullets each. The 

 following rations were fed : Pen 1, a scratch feed of wheat, oats, and barley 

 (15 : 2 : 2), and no mash ; pen 2, a scratch feed of wheat, peas, oats, barley, Kafir 

 corn, millet, sunflower seed, and buckwheat (12 : 2 : 3 : 2 : 1 : 1 :.5 : 05 : 1), and a 

 dry mash of bran, shorts, corn meal, wheat meal, fish-meat meal, and charcoal 

 (2:2:1:1:2:1) ; and pen 3, the same as pen 2 except that corn was substituted 

 for peas in the scratch mixture, and the proportion of oats and barley slightly 

 decreased. All the fowls were given green feed in some form throughout the 

 year. 



The fowls in pen 1 failed to keep in flesh, and those in pen 3 maintained 

 more uniform weights than those in pen 2, indicating that corn is essential in a 

 well-balanced poultry ration. During the year pen 1 laid 739 eggs, G6J per 

 cent of which were under 2 oz. in weight ; pen 2 laid 3,486 eggs, 5.5 per cent 

 of which were under 2 oz. ; and pen 3 laid 3,938 eggs, 6§ per cent of w^liich were 

 under 2 oz. 



Notes are given on balancing poultry rations. 



Poultry feeding test, home-grown versus purchased feeds (Minnesota Sta., 

 Rpt. Duluth Substa., 1916, p. 11; ahs. in Minnesota Sta. Rpt. 1916, p. 79).— Two 

 pens of 40 White Leghorn hens each were fed during January, February, and 

 March, 1916. In addition to other feeds the hens in tlie purchased-feeds lot 

 received corn and meat scrap and those in the home-grown-feeds lot, barley, 

 milk, and peas. The former lot laid 476 eggs and the latter 499 eggs within 

 the three months. 



DAIRY FARMING— DAIRYING. 



The daiiT industry in Argentina, P. Berges (An. Soc. Rural Argentine, 50 

 (1916), No. 2, pp. 81-131, figs. 21; ahs. in Internat. Inst. Agr. [Rome'[, Internat. 

 Rev. Sci. and Pract. Agr., 7 (1916), No. 9, pp. 1357-1362) .—The author treats 

 of the present state of tlie dairy industry of Argentina, sanitary inspection of 

 milk and butter, testing of milk intended for human consumption and butter 

 making, economic returns of the dairy industry, a comparison of the dairy 

 industry of Argentina with that of other countries, and plans for the develop- 

 ment of the dairy industry in Argentina. 



Net value of pasturage (Minnesota Sta., Rpt. Duluth Substa., 1915, pp. 7, 

 8). — l^'ive acres of pasture land seeded after clearing maintained an average 

 of three cows and two heifers for 30 days the first year after seeding, during 

 which time the total returns of beef and milk fat amounted to !?5.33 per acre. 

 It is estimated that this pasture land gave a total return of $10 per acre for 

 the whole season. 



[Pasturing experiments with cows at the Duluth substation] (Minnesota 

 Sta., Rpt. Duluth Substa., 1916, p. 7). — Continuing the work noted above, 4 

 cows were pastured on the same 5-acre tract for 137 days in the summer of 

 1916, receiving in addition 1 lb. of grain to each 4 lbs. of milk produced. Dur- 

 ing this time the cows produced 497.83 lbs. of milk fat. Valuing the milk fat 

 at 33 cts. per pound and the grain fed at .$25.95, the pasture was worth $13.83 

 per acre for the season. 



[Record of dairy herd at the Grand Rapids substation] (Minnesota Sta. 

 Rpt. 1916, pp. 75, 76). — Data are tabulated showing the results of five years' 

 work in breeding up a herd of common cows by the use of pure-bred Guernsey 

 sires.
