OHIO EXPERIMENT STATION: BULLETIN 187 



MANURE. 



Believing- thalfthe matter of manure production, long- considered 

 merely incidental to the feeding of live stock, but now recognized, 

 even in the western states, as an important phase of live stock 

 management, is deserving- , of thorough and extended study, data 

 concerning the amount and composition of manure produced by 

 each lot of lambs during the experiment were secured. It is be- 

 lieved that these data are of importance in showing something- of 

 the value of this long- neglected and even now not fully appreciated 

 by-product of the live stock industry. Bulletin 183 and Circular 37 

 of this Station, dealing with manure, its composition, value and 

 methods of handling, may be had upon application. 



TABLE XII Amount and percentage composition of manure produced by lambs in 115 1-2 days 



beginning December 22, 1906. 



The manure was removed from each pen once during the ex- 

 periment and again after its close. A few days before being re- 

 moved, the manure in each pen was sampled, samples being- taken 

 the entire depth of the manure in several parts of the pen. The 

 samples thus taken were analyzed under the direction of Mr. J. W. 

 Ames, Chemist of this Station, with results as presented in Table 

 XII. When the pens were cleaned for the second time, pens 2, 3 

 and 4 were noticeably dryer than pen 1. The manure produced 

 during this test was allowed to remain in the pens, unmoved, save 

 for what disturbance was due to the lambs moving- about, so had a 

 greater value than if it had been subjected to the wasting- effect of 

 the weather. As the pens were kept well bedded there was no dis- 

 comfort to the lambs from the accumulation of manure; in fact, this 

 method of handling- the manure is believed to be as satisfactory as 

 any, all things considered.
