FATTENING RANGE LAMBS.

gards cost would be very slight and the increased value of the 

 anure from lambs fed nitrogenous concentrates would more than 

 offset any slight difference in cost that might exist. The feeder who 

 purchases commercial fertilizers can calculate from the data 

 presented in this bulletin, together with the market prices which 

 prevail for the feeds used, whether or not the purchase of nitro- 

 genous concentrates will prove to be a paying proposition, so far as 

 the fertilizing value of the manure produced is concerned. 



TABLE 13 POUNDS FEED AND BEDDING USED PER TON OF 

 MANURE PRODUCED.* 



*See tatle 10 for composition of manure. 



Table 13 shows the amount of feed and bedding required by 

 each of the lots to produce one ton of manure under the conditions of 

 this experiment. It will be noted that the amount of feed and 

 bedding used by each lot approximately equaled in weight the 

 amount of manure produced. 



It must be thoroughly understood in this connection that the 

 manure under discussion was made and kept under cover, the pens 

 having been cleaned once during the experiment and again after its 

 close. Manure subjected to the leaching action of rains or allowed to 

 undergo the wasting chemical action known as "fire fanging" loses 

 much of its value and would be worth less than was the manure pro- 

 duced during this experiment. Furthermore, removing the manure 

 directly from the feeding pen to the field is usually the most 

 economical way of handling it, as well as being the most efficient in 

 preventing losses from leaching or from "fire fanging". For further 

 information relative to manure, its composition, and proper methods 

 of handling it, the reader is referred to Bulletin 134 and Circular 37 

 of this Station. 



FINANCIAL STATEMENT. 



The financial statement, Table 14, covers the time from the 

 beginning of the separate feeding of the four lots used in the exper- 

 iment until the lambs were marketed at Cleveland, hence it does not 

 correspond exactly with the figures given in Table 5 concerning the 

 value of food consumed during the experiment. No account is taken 

 of labor, interest on investment, insurance, manure produced, nor 

 beddinj? used.
