ceptionally good record this winter, having produced $4.28 worth 

 of butter per week on $1.75 worth of feed. 



Cow No. 6 did not freshen last year. She had produced 

 422 pounds of fat the previous year, and then produced 353 last 

 year which was, however, 69 pounds of fat less than last year. 

 This cow was 17 years old and was sold" Nov. 2, 1908. She was 

 not in calf. During this cow's last lactation period, beginning 

 Jan. 13, 1907, and ending Nov. 2, 1908 — twenty-one months, 

 twenty clays, she produced 16,814 pounds of milk and 761 pounds 

 of fat. During the five years she was tested she averaged 8,625 

 pounds of milk and 374 pounds of fat per year. 



On account of the fact that cow No. 2 died, No. 6 not fresh- 

 ening and No. 22 having been milked too long the previous year 

 the average of the herd dropped back to 307 pounds of fat last 

 year. Ten cows that were in the herd last year made an increase 

 of 18.7 pounds of fat over the previous year. 



Last fall two cows were sold and one very promising heifer 

 added to the herd. The cows this winter are doing exceptionally 

 well. 



Care of the Herd. 



Unless one cares properly for his cows and feeds them up 

 to their limit, you cannot hope to accomplish very much in the 

 way of raising the average production of the herd. 



Neither Colantha 4th Johanna nor Jacoba Irene could havve 

 made the records they did if they would not first have received 

 in their feed the protein, carbohydrates and other extract neces- 

 sary to maintain themselves and produce the milk and butterfat 

 that each cow produced. As much depends on care and feed as 

 upon weeding out the poor cows. 



During the winter months cows should be kept in a warm, 

 well lighted, and well ventilated barn. Too much emphasis can- 

 not be placed on good light and good ventilation. They are 

 essential to good health. The best way to ventilate a barn is by 

 the King system. A description of this system is found in 

 "Physics of Agriculture" by Prof. F. H. King of Madison, Wis.
