| Show PLAN FOR constructing ETE SILO V 4 40 X 1 e I 1 well constructed silos prepared by tha united states department of agriculture A well constructed homemade home made silo will last indefinitely and there la Is no danger of its blowing down rotting out or being attacked by vermin says bays farmers bulletin of the united states department of agriculture the cost of the homemade home made silo depends so BO much on the size of the silo and on the local price of materials that no definite amount can be assigned which would be applicable to all conditions recently collected data on the cost ot of homemade home made silos ellos show an average cost of concrete silos alloa to be per ton capacity the stave silos cost and the modified wisconsin per ton capacity silos ot of small diameters cost more per ton capacity than silos of large diameters thero there are some features which are essential to the construction of all silos and without which silage will not be kept in perfect condition 1 the walls should be airtight air tight since tho the keeping of silage depends upon the exclusion of air it Is imperative that the walls walla of the silo ello be built in such a way as to keep out the air the lumber should be ba well matched and that containing large knots should be rejected in concrete silos a wash an tho the inside with cement or with raw coal tar thinned with gasoline Is effective in making the walls impervious to air care should be taken that the doors fit closely into their frames 2 the walls should be smooth and plumb so that the silage will not adhere to them in settling and thus cause cause air spaces in the outer edge of the silage furthermore the walls should be capable of standing considerable lateral strain without cracking or bulging this Is one reason why rectangular ellos altos are unsuccessful 3 the silo must be deep enough so that the pressure frow from above will thoroughly pack the silage and force out the air the greater the pressure pree sure the less air in the silo and the less will be the loss of nutrition materials by fermentation 4 the only form of silo to be becom beaded Is one which Is round this form Is the cheapest capacity condid A ilse small sized silo ered and the walls walla are more rigid than those of the rectangular or octagonal forms this results in moro more per act feet preservation of the silage the silo should be placed outside rather than inside the barn AS a silo ordinarily does not aled the the protection of a barn it is not economical to use barn space tor for this purpose an exception to this rule may bo made in the case of the round barn A silo in the middle of a round barn serves to support the superstructure as well as to place the silage iu in a position for convenient feeding A silo so placed however is liable to be ba very inconvenient to fill the most popular location Is not more than a few feet from the barn and opening into a separate feeding room the door of the barn can then be closed and the silage odors odora kept out of the stable at milking time the silo should not be built in the ground so deeply as to make it necessary to lift the silage more than five feet in getting it out from the bottom to lia other words worda the bottom should not be more than five feet below the lowest door the size and capacity of the silo tho the diameter of the silo will depend upon the amount of silage to be fed dally daily the silage should be removed from the top at the rate of 1 to 8 inches per day depending upon all matte matle conditions the warmer the weather veather the more silage must be ba removed from the surface dally daily in order to prevent spoiling for the winter feeding season it Is safer to figure upon removing two inches dally daily rather than a smaller amount A common error in building la Is to make the diameter too large for the size ot of the herd the weight of a cubic toot foot of silage varies according to the pressure to which it la Is subjected but in a silo ello 30 feet deep it will average about forty pounds so by knowing the amount of silage to be fed dally daily it la Is possible to estimate what the diameter of the silo should be to permit the removal of oe a certain number of inches in depth each day the following table will prove of interest to those contemplating building silos relation of size of herd to diameter of silo allo for winter feeding on basla basis of 40 pounds of silage per cubic toot foot number numb r ot of animals a that w v 10 c may isy be fed 3 allowing allow 3 0 0 C P 1 1 0 8 9 a 8 ta K 0 ty S M Us as as J P M 9 sr u u a 9 1 w 19 q s 1 i 4 i itt tsi a 3 sr w tf 0 p T 1 P 3 S 1 i a a 0 SDI 0 0 11 10 13 17 28 35 it 11 13 16 21 at 31 42 12 15 1 1 19 25 ST 37 to 60 13 22 29 44 6 65 14 16 25 34 84 61 51 68 is 15 1173 13 1 23 19 39 ea 78 18 16 1340 33 44 67 89 17 SS as so 60 73 75 is 13 1633 42 3 69 66 83 95 ila 20 2094 62 70 in 13 |
