Missouri Agricultural Report. 



In one feeding test we fed a lot of 48 Angus calves, born in the 

 Panhandle of Texas and sent through to our Ohio farm. We fed 

 them 390 days. Their initial weight was 448 pounds and their final 

 weight 1,150 pounds. They consumed during the period 11.9 

 pounds of grain per day per 1,000 pounds of live weight, and 6V2 

 pounds of hay, with 6.7 pounds of silage, the whole ration contain- 

 ing 17.6 pounds of dry substance. 



Two other lots of western cattle, one containing 30 and the 

 other 28 head, were fed 182 days, and a fourth lot of 63 heavy cattle 

 were fed for 49 days. 



In the second part of this table is shown the average gain per 

 head in live weight for each of these lots, both for the total period of 

 the test and per day; the dry substance consumed for each pound 

 of gain in live weight, and the amount of manure produced, both 

 over the total period for each animal, and per thousand pounds 

 live weight per day, calculated both with and without the straw 

 used as bedding. 



The chief purpose for which I have prepared this table is to 

 bring out the actual amount of manure produced. It shows that 

 there was a daily production of 89 pounds of manure per 1,000 

 pounds of live weight by the young cattle, that is, the calves and 

 young stock, to nearly 50 pounds of manure per 1,000 pounds of live 

 weight for the older cattle. In other words, the older cattle have 

 produced more manure, not only actually but relatively, than the 

 young. 



In table II is shown the quantity of nitrogen, phosphorus and 

 potassium contained in the feed and bedding consumed in these 

 tests, as calculated from average analyses ; the cost of the feed and 

 bedding ; the quantities of these elements recovered in the manure, 

 as determined by analyses of the manure by Mr. J. W. Ames, chem- 

 ist to the Ohio Station, and the value of these constituents at the 

 rate at which they are valued in tankage and muriate of potash by 

 the Secretary of the State Board of Agriculture, who is charged 

 with inspection of fertilizers in our State.
