Again the manure collected by stabling the cows at 

 nigM, March 26th to 30th, was weighed, one lot of cows 

 then getting the cowpea ration, the other the wheat bran 

 ration. The average daily production of liquid and solid 

 manure, free from'bedding, was 28.3 pounds, or, includ- 

 ing fine straw bedding, 29.6 pounds, or 888 pounds per 

 cow per month. 



During the next five days the six cows were kept in 

 the stable continuously, except for the few minutes re- 

 (juired twice daily for watering, at which time they were 

 watched to see that no manure was lost. The ration 

 was the same as during the preceding five days, three 

 cows receiving the cowpea hay ration and three the 

 wheat bran ration. 



Under these conditions of continuous stabling the 

 average daily production of manure was 56.8, exclusive 

 of bedding; the total, including pine straw bedding, was 

 58.3 pounds. Comparing these r mounts, we find that 

 50 per cent, of the net manure wa'> dropped during eight 

 hours out <;f doors and an equal amount during sixteen 

 hours in the barn. This is in close agreement with 

 previous tests made at this station and recorded in 

 Bulletin No. 114 : 



"This is important because the manure dropped on the 

 lots or pastures usually suffers greater losses, and 

 hence is worth less than that collected while the cows 

 jire in the stable. However, the high value of manure 

 from grain fed cows should prompt every dairyman to 

 gather and protect the manure from the lot as well as 

 that from the barn." 



This is equivalent to a production of 1,741) pounds of 

 manure per cow per month, including bedding, or to 

 three and one-half tons during a stabling period of four 

 months, half of which (dropped in the barn), and a 

 part of that dropped in the lot, would be saved. 



It is of interest to note that during the time covered 

 ])y these tests each pound of dry food con-^umed resulted 

 in the production of about two and one-half pounds of 

 Manure.
