Show PLAN FOR constructing CONCRETE SILO A K M e A well constructed silos prepared by tl the e 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 deportment department of agriculture tho cost of the homemade home made mada silo depends so much on the size elzo of the silo and on the local price ot of materials that no definite nite amount can be as signed which would be ba applicable to all conditions recently collected data on tho the cost of homo home mado made silos ellos show an average cost of concrete silos to be per ton capacity the stave silos cost and the modified wisconsin per ton capacity silos of small diameters cost more per ton capacity than siloe of large diameters there are some features which are essential to the construction of all silos and without which silage will not be kept to in perfect condition I 1 the walls should bo be air tight aln since e tho the keeping of silage depends upon tho the exclusion of air it Is imperative that the walls of the silo be built in such EL a way as to keep out the air the lumber should be well matched and that containing large knots should be rejected in concrete silos alloa a wash on the inside with cement or with raw coal tar thinned with gasoline to la effective in making the walls walla impervious to air care should be taken that the doors fit closely into their frames 2 the walls should be smooth and plumb no BO that the silage will not adhere to them in fit settling and thus cause air spaces iri in the outer edge of the silage furthermore the walls should be capable of standing considerable lateral strain without cracking or bulging this la Is one reason why rectangular silos are ara unsuccessful 8 the silo atlo must be deep enough so that the pressure from above will thoroughly pack the silage and force out tate air the greater the pressure the less air in the silo and the tha less will be the loss of nutrition materials by fermentation 4 the only form ot of silo allo to be becom reto M beaded Is one which Is round this form is the cheapest capacity considered aft e NV M Z A iza 41 1225 W m small and the walls walla are more rigid than those of the rectangular or octagonal forms forma this results in more perfect fact preservation of the silage billage fil lage the silo should be ba placed outside rather than inside the barn As a silo ordinarily does not need 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 caselt the round barn A silo in the middle ot of a round barn serves to support the superstructure as well as to place the silage in a position for convenient feeding A silo so placed however is liable to be very incon inconvenient lenient to fill the most popular location la 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 odore kept out of the stable at milking time the silo should not be built in the ground so BO deeply as to make it necessary to lift the silage more than five teet leet in getting it out from the bottom to n other words worda the bottom should not bo be more than five foot feet bolow below the tha lowest door tho the size and capacity of the silo the diameter of the silo ello will depend upon the amount of salago to bo be fed dally daily the silage should bo be removed from the top at the rate of 1 to 2 3 inches per day depending upon ell matte matle conditions the wanner tho tha weather the more silage roust must be removed from the surface dally daily in order to prevent spoiling spelling for the winter feeding season it ft is safer to figure upon removing two inches dully dally rather than a smaller amount A common error in building Is in to make the diameter too largo large for the size of tho herd tho the weight of a cubic toot foot of silage varies according to the pressure to which it is subjected but in a silo elto 30 feet deep it will average about forty pounds so by knowing the amount of silage to be fed dally daily it Is possible to tc estimate what the diameter of tho tha 0 allo ila should be to permit tho the removal of a certain number of inches in depth each day the following table will prove of interest to those contemplating build ing silos relation of size of herd to diameter of silo for winter feeding on basis of 40 pounds of silage per cubic foot number of animals that wb g 0 o 4 may y be bc fed 6 ITS Z 0 gs r t m j t is a 8 a IA 0 sa S a a g 9 a a E s 9 if 1 ma tr ty tf cr w 4 A 0 A fa 0 PM 5 0 5 0 p h j di C Q 6 a 10 13 17 28 26 85 it 11 is 18 21 31 42 2 10 12 19 29 25 ST CO 13 22 n 29 44 C 14 25 14 84 EL 51 63 68 is 13 1178 29 39 69 79 is 18 1340 33 83 44 6 67 89 17 1613 as 83 60 71 75 IS 1608 2696 43 42 63 68 85 20 2094 62 52 70 |
