502 EXPERIMENT STATION RECORD. 



tone feed used is a slaughter liouf^e l)y-i)r(Hlnct made from tlie partly-digested con- 

 tents of the paunches of cattle. The ])igs given this feed made tlie largest percentage 

 gains in the 66 days of the test and at the least cost. 



The American saddle horse, J. B. C.\stleman ( T. ,S. Depl. A(/r., Bureau of Ani- 

 VKil liidiixlnj Rpt. HXKJ, pjt. 62-78, ph. 5). — The origin and development of the 

 vVmerican saddle horse, sizi', and other refjuirenients are discussed. 



Fattening horses for market, W. J. Kknnedv ( Wallaces' Farmer, 28 {1903), 

 No. 4^, p. 1S63). — The fact that increased profits may attend fattening liorses before 

 marketing them is pointed out, a full grain ration with an abundance of forage being 

 recommended for the purpose. The author states that many find clover a satisfao 

 tory coarse fodder, and corn, oats, and l)ran a good grain mixture. Coolied or 

 steamed grain twice a week is recommended with some oil meal or flaxseed added. 

 Glauber salts once a week is also useful, especially as the horses are given little or no 

 exercise. Feeding horses 4 or &times a day is recommended. "Horses on full feed 

 should gain from 3 to 5 lbs. per head per day." 



Distribution and magnitude of the poultry and egg industry, G. F. 

 Thompson ( U. S. Dept. Agr., Bureau of Animal Industry Rpt. 1902, pp. 149-213). — A 

 statistical article based largely on reports of the last census. A part of this article 

 has been noted from another publication (E. S. E.., 15, p. 291). 



DAIRY FARMING— DAIRYING. 



Studies in milk production, W. L. Carlyle and F. W. Woll ( Wisconsin Sta. 

 Bui. 102, pp. 88, figs. 10, dgm. i).— During the period from the fall of 1898 to May, 

 1903, complete records were obtained of 38 cows, comprising 8 grade and 4 pure- 

 bred Jerseys; 9 grade Guernseys, 1 grade and 4 pure-bred Holsteins; 8 grade and 3 

 pure-bred Shorthorns; and 1 grade Red Polled cow. The records obtained during 

 the first 2 years of this period were discussed in previous reports of the station (E. 

 S. R., 12, p. 83; 13, p. 81). The main part of the data previously presented, how- 

 ever, is included in this bulletin, which contains illustrations and descriptions of 

 the cows, detailed data for the food consumption and the production of each, and a 

 discussion of the results from different standpoints. "The primary object of the 

 investigation has been to ascertain the capacity of the various cows for a large and 

 economical production of milk and butter, and to study the system of feeding which 

 was required to reach this end, in case of the individual cows in the herd. The 

 general plan of feeding adopted has been the one which we consider the fundamental 

 requirement in the successful management of a modern dairy, viz, to feed each cow 

 as much rough feed as she will eat iip clean and, in addition, such amounts of the 

 available common concentrated feeds as she will give returns for in production of 

 milk without any material change in live weight, the character and amounts of grain 

 feed being therefore adjusted according to the peculiar characteristics of each cow." 

 The average annual production of the 38 cows for 4 years was 7,340 lbs. of milk, and 

 307 lbs. of butter fat, equivalent to 370 lbs. of butter per head. The main results of 

 the work as summarized by the authors are as follows: 



"(1) The average annual yield of milk for the various cows in the herd ranged 

 from 10,960.3 to 4,033 lbs., the production of fat ranged from 474.73 to 183.64 lbs., 

 and the net profit returned by the cows from $79.31 to $19.59. The highest average 

 production per year for any cow in the herd was that of the Jersey cow, Gold, which 

 is credited with a production of 7,621.6 lbs. of milk and 474.73 lbs. of ])utter fat, and 

 a net profit (value of butter and skim milk minus cost of food) of $79.31. This cow 

 also produced the maximum amount of butter fat of any cow in the herd during 365 

 consecutive days, viz, 502.12 lbs., and returned the highest net profit of any cow 

 during this time, with $84.55. Twenty-two of the cows produced more than 300 lbs.
