DAIRY FARMING— DAIRYING— AGROTECHNY. 



The university dairy herd, 1905-6, (J. V. Humphrey and F. W. Woll {Wis- 

 consin 8ta. Rpt. 1906, PI). 60-90, (Ignis. 2). — The records of the station herd 

 during the year are reported and discussed in the same form as in the previous 

 report (E. S. R., 18, p. 273). 



The herd comprised 32 cows representing Jersey, Guernsey, Holstein, Short- 

 born, Red Polled, and Brown Swiss breeds. Three cows added to the herd 

 during the j-ear are described. The tabulated data show the amounts of the 

 different kinds of feeds consumed and the milk and butter produced by 30 cows 

 for which a full year's record was obtained. The average yield for the herd 

 was 7,32S.(; lbs. of milk and 303.'54 lbs. of butter fat. The largest yield of butter 

 fat, 449.73 lbs., was produced by a grade Red Polled cow. The average net 

 profit per head was $41.20 as compared with $35.20 during the preceding year. 



The average production of the 30 cows by breeds was as follows: Jersey (7 

 cows), (!,247.7 lbs. of milk and 318.46 lbs. of butter fat; Guernsey (7 cows), 

 0,401.1 1I)S. of milk and 300.50 lbs. of butter fat; Holstein (7 cows), 10.170.4 lbs. 

 of milk and 340.34 lbs. of butter fat; Shorthorn (3 cows), 4,007,7 lbs. of milk 

 and 185.30 lbs. of butter fat ; Red Polled (4 cows), 7,712.3 lbs. of milk and 300.(»7 

 lbs. of butter fat ; and Brown Swiss (2 cows), 0,!)54.3 lbs. of milk and 275.19 lbs. 

 of flutter fat. .The average butter fat production of these breeds for 1898 to 

 1900 wiis as follows : Jersey, 312.0 lbs. ; Guernsey, 297 lbs. ; Holstein, 337.5 

 lbs. ; Shorthorn, 204.7 lbs. : Red Polled, 295.5 lbs. ; and Brown Swiss, 278 lbs. 



As in i)revi(ms reports, a comparison was made of the different cows by types. 

 The data are considered mifavorable to the dual-purpose type. 



Analyses were given of the feeding stuffs used. In general it was found that 

 a high production was associated with the feeding of a ration containing a 

 largo amount of dry matter or digestible protein and a narrow nutritive ratio. 



The value of individual records of dairy cows, B. E. Carmichael {Oh in 

 8tu. Circ. 67, pp. 10. ptix. ■]). — The records of 2 cows for 3 j'ears are presented 

 in this circular for the purpose of illustrating the value of accurate knowledge 

 concerning the production of each cow in the dairy herd. One cow produced on 

 an average for 3 years 5,754.9 lbs. of milk and 330.2 lbs. of fat at a profit of 

 $50.72 over cost of food, and the other cow 7,365.1 lbs. of nulk and 231.4 lbs. 

 of fat at a profit of $24.82. These are not believed to be (>xtrenie differences, 

 but such as might be found in average untested dairy herds.
