Robinson method of breeding squabs, E. C. Rice {Bo>itoii: Plymouth Rock 

 Squab Co., 1902, pp. 79, pi. 1, figx. 41 -, dgms. 7). — Detailed directions are given for 

 raising squabs for market. The volume embodies the results of a number of years 

 of practical experience. 



DAIRY FARMING DAIRYING. 



Feeding experiments with dairy cows, C. 1). Smith {Mlcltigan Sta. Bui. 193, 

 pp. 16-19). — The feeding value of sugar-beet pulp was tested with 2 lots of 4 cows 

 each. The experiment covered 2 periods of 6 weeks each, the first week in each 

 period being considered as preliminary. Pulp was fed to lot 1 during the first period 

 and to lot 2 during the second period, a hay and grain ration being fed to both lots 

 throughout the experiment. Both lota increased in weight when eating pulp, and 

 lost in weight on dry feed alone. When pulp was fed the 2 lots ate 9,463 lbs. of 

 pulp, 3,381 lbs. of hay, 2,259 lbs. of bran, and 1,124 lbs. of corn meal, and when no 

 pulp was fed 3,649 ll)s. of hay, 2,431 lbs. of bran, and 1,217 lbs. of corn meal. The 

 amount of pulp eaten was therefore offset by 268 11 )s. of hay, 172 lbs. of bran, and 

 93 lbs. of corn meal. When fed pulp the 2 lots gave 7,258.6 lbs. of milk and 259.67 

 lbs. of butter fat, as compared with 6,843.6 lbs. of milk and 258.27 lbs. of fat when 

 no pulp was fed, showing prai-tically no increase in the yield of fat due to feeding 

 pulp, but a total increase of 415 lbs. in the yield of milk. 



Feeding trials with dairy cows, D. A. Gilchrist and A. C. Hall {Reading 

 Col., Agr. Dept. Rpl. 1901, jjp. 42-46). — Three rations made up of different combina- 

 tions and quantities of mangels, brewers' grains, oats, wheat, beans, and cotton-seed 

 cake in addition to 6 lbs. of straw and 20 lbs. of hay were compared with 3 lots of 4 

 cows each. The test proper lasted 6 weeks. The ration composed of 28 lbs. of man- 

 gels, 2 lbs. of oats, 1 lb. of wheat, and 5 lbs. of cotton-seed cake gave the best results. 



Experiments with dairy cattle, J. H. Grisdale {Canada Expt. Farms Rpfs. 1901, 

 pp. 269-277). — Tabulated data are given for 3 experiments conducted to ascertain the 

 influence of milking cows at equal and unequal intervals. The results confirm the 

 conclusions stated in the previous report that where the intervals between milkings 

 are unequal the richer milk is produced after the shorter interval and that where the 

 intervals are equal there is no appreciable difference in the quantity or the quality of 

 the milk. 



An experiment with 2 lots of 3 cows each is reported in which a ration consist- 

 ing of barley, oats, and oil meal fed dry was compared with a ration consisting of 

 bran and gluten feed fed wet. The rations were fed for 2 periods of 14 days each, 

 and were reversed at the end of the first period. On the ration fed wet the 6 cows 

 gave a total daily yield of 114 lbs. of milk, containing 3.83 per cent of fat, and on the 

 ration fed dry a daily yield of 116^ lbs. of milk testing 3.99 per cent of fat, showing 

 an increased daily yield of butter fat of 6 per cent in favor of dry feed. 



Dairying in the South, S. M. Tracy ( U. S. Dept. Agr., Farmers' Bui. 151, pp. 48, 

 figs. 4). — The natural advantages of the South for dairying are pointed out and sug- 

 gestions are given concerning the construction of dairy buildings, the formation and 

 management of a dairy herd, watering and feeding cows, handling milk, butter 

 making, etc. 



Dairy herd records, J. H. Grisdale, R. Robertson, and S. A. Bedford {Canada 

 Expt. Farms Rpts. 1901, pp. 266-269, 357-359, 422). — Records for one year are given 

 of 19 cows at the Central Experimental Farm, of 22 cows at the Experimental Farm 

 for the Maritime Provinces, and of 21 cows at the Experimental Farm for Manitoba. 



The milk of spayed cows, H. Lermat {L'Ing. Agr. Gemhloux, 12 {1902), No. 11, 

 pp. 616-523). — Analyses of the milk of spayed cows showed no more uniformity in 

 composition than ordinary milk. In general there was a notable increase in the 

 content of fat and sugar and to some extent in the content of casein. The author 

 considers that such milk is especially s'.iited for infants.
