OF- TRAP 



FIG. 13. A GUTTER TRAP 



T9 prevent clogging of the drain pipe 

 leading from the stable gutter a homemade 

 trap may be built in. 



The size of stalls varies. The width of mangers is practical- 

 ly standardized at two feet six inches. The average length of 

 a cow stall, from the manger to the edge of the gutter, is four 



feet eight inches. If it is 

 necessary to vary this 

 length, the stall could be 

 constructed four feet six 

 inches at one end, slanting 

 to five feet or more, at the 

 other. By having the stall 

 of correct length all the 

 manure can be confined to 

 the gutter and the cows kept 

 clean. The w'dth of the 

 stall is standard at three 

 feet six inches. For large 



cattle, weighing 1,400 to 1,600 pounds, it will probably be 

 necessary to make the stall three feet eight inches wide and 

 five feet long. 



While the gutter width varies from 14 inches to 20 inches, 

 18 inches is the most satisfactory width. The depth of the 

 gutter at the edge next to the cow should not be more than 

 eight inches. The depth at the rear of the gutter should not 

 be more than four inches as shown in Figure 12. The gutter 

 should have a slight slope away from the cows. It should also 

 be given a slope of two inches in 50 feet lengthwise of the barn 

 so that the gutter may be flushed easily. This slope is de- 

 sirable for flushing the liquid manure especially where a 

 cistern is provided. In long barns of more than 50 feet, the 

 slope should be from the ends towards the center. For such 

 a slight slope, the gutters must have a very smooth finish. 

 To prevent clogging of the drain pipe some means should be 

 used to prevent the entrance of chaff and other coarse ma- 

 terials. A homemade trap as shown in Figure 13 will serve 

 this purpose. 



WIDE FEED ALLEYS BEST 



Feed alleys should be four or more feet in width. Cows 

 have a habit of pushing forward in their stalls which makes 

 it all the more difficult to feed from alleys of less than four 

 feet. Passageways between long rows of stalls or at ends of
