Fig. 9. Present barn arrangement on one faiin. 



On two farms the travel of the operator in doing the chores was re- 

 corded by laying down a string on a bam plan as shown in cut on front 

 page. A study of the resulting picture and measurement of the string 

 indicates that on one fann, the one and one-quarter miles of walking in 

 one evening to clean the stable, water the cows, and milk, could be 

 materially lowered. This would necessitate some re-location of stock 

 and some minor changes in barn arrangement. 



The arrangement of bams will be discussed in more detail in a later 

 bulletin, but one illustration here will serve to show the need of re- 

 arranging some of the older ones. Figures 9 and 10 show the present 

 and the suggested arrangement of tie-ups, calf pens and milk house. 

 At present a large amount of space per cow is allowed for walks and 

 feed alleys. The operator walks 2,050 feet at each milking from the 

 cows to the milk room. The proposed rearrangement of the milk house 

 and tie-up would reduce this traveling by two-thirds. The time spent in 

 feeding grain would be materially reduced by using a feed cart. By 

 building a hay chute, the roughage could be dropped from the mows 

 directly into the feed alley. This rearrangement would place all the 

 cattle on one floor and save an hour a dav 



in doing the chores. 



Roughage Production 



Efficiency in roughage production is more important than the time 

 per unit indicates because much of the work comes at a peak period 

 and may result in hiring extra labor. Efficiency in this field work may 

 enable the operator to carry more cows with the same energy or per- 

 haps to take care of the same numl^cr of cows with less dmdgeiy. 



The labor reciuired for producing all roughage ranged from 13 to 52 

 hours per cow with an average of 25 per cow. The 13 farms requiring 

 the least amount of time per cow on roughage production averaged
