![]() Top-unloading silos have a rotating scraper that sweeps silage through openings in the wall into a chute mounted on the side. Special unloading equipment is mounted inside. The forage consolidates under its own weight. These are referred to as cast-in-place silos.įorage is blown into the top via a pipe mounted on the silo's side. Another construction method is by placing concrete inside a form. Some concrete silos, called stave silos, are built from concrete staves, 30 cm wide by 75 cm high concrete slabs that are stacked up into a cylindrical wall and held together with steel hoops, very much like a wooden wine barrel. Tower silos are 15-30 m high cylindrical concrete or steel structures, usually closed with a domed roof. The size of the silo will depend on the size of the herd to be fed. Unloading is by front-end loader or by allowing cattle to feed directly from the exposed face of the silage. Forage is dumped within the walled area, compacted by tractor, covered with polyethylene sheets and weighed down with old tires. They are found more often on large beef farms.īunker silos are paved areas surrounded on 3 sides by concrete or 3-5 m high concrete or timber walls. Bunker silos, sometimes called horizontal silos, are cheaper to build than tower silos but allow little automation and have the greatest feed loss by oxidation. The bottom-unloading tower silo allows a greater degree of automation but is somewhat more expensive to build. With well-ensiled material in anaerobic storage, the quality and palatability of the feed is maintained until the material is exposed to oxygen, which causes silage to deteriorate quickly. Under normal conditions, silage-producing microbial fermentation produces lactic and acetic acids until acidity is such that growth of all micro-organisms stops (after 2-3 weeks). High-moisture grains (eg, whole-shelled, ground-shelled and ground ear corns and barley) go through the same fermentation process as silage but contain far less water. Whole-plant corn silage (30-35% dry matter) is made by chopping the entire plant finely (1-2 cm) haylage is silage composed of wilted grass or alfalfa dried to 35-50% dry matter, again chopped finely. Silage is formed by microbial fermentation of plant material under anaerobic (oxygen-free) or near-anaerobic conditions. Silos are a common fixture in livestock and mixed-farming operations across Canada. When planning your forage programs, remember that your main objective is to "store the plant and remove it from storage in as good condition as possible." THE UPRIGHT SILO IS WITHOUT EQUAL IN ITS ABILITY TO DO THIS.Farm silos are storage structures for silages and high-moisture grains used for livestock feeds.Our thicker, stronger walls help silage remain at a relatively constant temperature, resisting freezing and heat damage, and resulting in less spoilage and better silage. ![]() Concrete strength, wall thickness, and steel schedules all exceed standards set by the International Silo Association, of which we are a member.The outside ladder is hot-dip galvanized and cast in the wall to make a permanent, rigid ladder.Extra large cedar doors for longer life and greater strength, with steps and door hardware protected by hot-dip galvanization.Our poured concrete chute is an integral part of the silo poured along with and tied into the wall.The steel inside the walls is protected from silage acids and weather. Tying horizontal and vertical steel together inside the concrete wall, creates tremendous strength to keep the silo round and resist storm damage.Our 6" concrete walls have 780x more heat-resisting ability than steel, and 25x more insulating power than steel.Our 6" thick solid concrete wall of 4,000 psi air-entrained concrete has a low-leak potential and is very low maintenance: no plaster needed now, or resealing in a few years.Our 6" walls are a monolithic (one piece) structure, with smooth and uniform diameter walls that help your unloader work more efficiently.Our 6" thick (horizontal and vertical) solid concrete walls are strong enough to withstand heavy loads.We would be glad to give you a free, no-obligation quote.Ĭonsider The Many Advantages of Poured Concrete Silos!!! Not sure if a new silo is right for you? Contact us. With robotic unloading and feeding systems, many farms have been able to greatly reduce their labor costs. Another thing to consider is the lower labor requirements of an upright silo. The limited spoilage and lower dry matter loss of a poured silo has helped many farms increase their efficiency. When choosing feed storage, it is important to consider the effect that feed quality has on the profits of your farm. Silos store from 100 tons to 3,000 tons or more. Poured concrete silos are the best in feed storage.
