Inventive concepts relate generally to apparatus and methods for preparing feed for livestock, in particular dairy cattle and beef cattle.
Generally speaking, livestock feed compositions provide animals with the protein, carbohydrates, fiber, vitamins, and minerals they require. Livestock feed compositions can be the primary source of food for the animals, or they can be designed to provide a supplement for animals that eat forage with the extra protein and energy they require to complete their diet.
The majority of feed consumed by cattle is typically forage. Generally, when an animal eats forage, it grazes on grass in a pasture or field, or eats some type of preserved forage such as hay, silage or haylage. Dietary supplements can provide cattle with additional minerals, vitamins, and other compounds they may require to meet specific needs. These supplements can be provided in loose form (which can be added to feed as desired), or block form (such as solid blocks that animals can lick).
Factors that can impact the type of feed cattle require include, but are not limited to, the type of cattle (for example, show cattle, dairy, or beef cattle), age of the cattle, reproductive stage, life stage, overall feeding program (such as pasture cattle), and pasture conditions.
Many dairy farmers work with nutritionists to create a feed ration (recipe) that is best suited for their cows. This ration is dependent upon where the farm is located and what feed types are most commonly available, among other variables. High quality feed is important for a cow's health and milk production.
Typically, dairy farmers aim for a ration consisting of about 50-60% forage. Forage consists of plants that are consumed mainly by grazing livestock, such as grass or hay. Dairy cattle are often supplemented with grain to increase the efficiency of production. For lactating cows, a high energy diet increases milk output, measured in pounds or kilograms of milk per head per day.
There are two groups of forages, namely, wet and dry. Exemplary wet forage is silage (fermented forage). Commonly, silage on a dairy farm can consist of barley, corn, or alfalfa. Dry forages are pasture (fresh forage) or high-quality alfalfa hay, alfalfa-grass mix hay, grass hay or straw. Feed can consist of silage, hay, straw, or a mix of two or more of these.
The remaining portion of the diet is referred to as the concentrate. The concentrate is composed of carbohydrates, proteins, fats, minerals, and vitamins.
Feed costs represent the largest annual operating cost for most commercial cow-calf enterprises. A major overall desire of dairy farmers and ranchers alike is to reduce the overall cost to produce a product, such as milk or beef, with an acceptable level of quality. The business of milk production has also become very competitive; profits are realized more readily when feed is utilized efficiently and when cows produce their maximum amount of milk.
Current methods of formulating feed rations on-site involve introducing baled straw into a chopper to comminute the straw, and mixing the comminuted straw with other components such as silage, protein, and other components of the concentrate (e.g., minerals and vitamins).
In recent years, corn silage has become a more prominent component of dairy cow diets. Corn silage provides a cost-effective source of nutrients. However, attention must be paid to harvesting and processing the corn silage to provide optimum results.
Generally speaking, the present disclosure relates to apparatus and methods for preparing livestock feed, and in particular, feed for dairy cattle.
In some aspects, inventive concepts provide a livestock feed sorting assembly comprising a metering unit and a sorting unit, wherein the metering unit is configured to receive corn silage and transport the corn silage in a controlled manner toward the sorting unit. The sorting unit, in turn, acts to separate particles making up the silage composition into size fractions. These separated size fractions can be utilized to formulate livestock feed.
The metering unit can be provided as a hopper having a tapered configuration, such that the top, open end is larger and tapers downward to a lower, trough portion. In use, silage is introduced into the top, open end and moves downward (e.g., is urged downward) toward the trough portion. The trough portion, in turn, contains a conveyance device such as an auger, conveyor, or similar device that transports the silage in a controlled manner to the sorting unit. The conveyor can be configured as a roller chain or belt conveyor. The sorting unit can be provided as a screen material configured as a rotating drum, shaker deck, oscillating deck, or similar separating apparatus.
In some aspects, inventive concepts provide a livestock feed sorting assembly comprising:
In some implementations, the conveyance device comprises an auger positioned within the trough, the auger having a first end and a second, free end.
In some implementations, the conveyance device comprises a conveyor positioned within the trough, the conveyor having a first end and a second end. The conveyor can comprise any suitable conveyor apparatus, such as a belt conveyor or chain conveyor.
In further aspects, inventive concepts provide a livestock feed sorting assembly comprising:
In some implementations, the conveyance device comprises an auger positioned within the trough, the auger having a first end and a second, free end.
In some implementations, the conveyance device comprises a conveyor positioned within the trough, the conveyor having a first end and a second end. The conveyor can comprise any suitable conveyor apparatus, such as a belt conveyor or chain conveyor.
The hopper can be provided with a fixed, adjustable angle of inclination. In this way, the end user can adjust and set the angle of inclination to thereby control the rate of transport of silage through the hopper and into the sorting unit.
In some implementations, the conveyance device of the hopper can extend from the hopper at an adjustable angle. In these aspects, the hopper can remain at a fixed position, and conveyance device can extend from the hopper toward the sorting unit. The angle of the conveyance device can be adjusted and set to provide a desired rate of transport of silage from the hopper and into the sorting unit.
The one or more rotating rods can include studs that project from the surface. The studs can assist in moving silage downward within the hopper, and toward the conveyance device. In some embodiments, the hopper includes two rotating rods. The rotating rods can be the same or different.
In some aspects, the conveyance device (auger or conveyor) is driven by a force applied to the first end.
Optional features of the rotating drum include the following. The drum can have a constant or variable diameter along its axis. The screen can have a uniform aperture size (diameter of an individual aperture), for example, an aperture size of 0.75 inches throughout the screen. Alternatively, the screen can include apertures of different sizes within the same drum. The size of the apertures within the screen can vary depending upon such factors as the amount of retentate to capture, particle size in the parent material, desired range of fines particle size to be collected, and the like. The drum can be pitched at a fixed, adjustable downward angle from the intake end. In some aspects, the drum can be provided at a downward slope of about 10 degrees or less, or about 9 degrees or less, or about 8 degrees or less, or about 7 degrees or less, or in a range of about 1 degree to about 8 degrees, or about 2 degrees to about 8 degrees, or about 3 degrees to about 8 degrees, or about 6 degrees to about 8 degrees.
Likewise, when the sorting unit comprises a shaker deck or oscillating deck, the shaker or oscillating deck can be provided with a length, width, and depth suitable for containing and separating silage into desired size fractions. The screen can have a uniform aperture size, for example, an aperture size of 0.75 inches throughout the screen. Alternatively, the screen can include apertures of different sizes within the same shaker deck. The size of the apertures within the screen can vary depending upon such factors as the amount of retentate to capture, particle size in the parent material, desired range of fines particle size to be collected and the like. The shaker deck can be pitched at a fixed, adjustable downward angle from the intake end. The shaker deck can use gyratory vibration to separate materials by size, and, in some aspects, can be set to a shallow angle relative to the horizontal level plane, typically no more than 2 to 5 degrees relative to the horizontal plane.
In some implementations, the livestock feed sorting assembly can be assembled on a moveable platform, such as a trailer that can be pulled by a vehicle. In these aspects, inventive concepts provide a mobile livestock feed sorting assembly that can be transported to a desired location and utilized to prepare a livestock feed ration. Beneficial features include improved efficiency and reduced cost, since silage materials can be processed on site, without the requirement that they be moved to a separate processing location.
Also contemplated are methods of preparing a livestock feed ration, the method comprising steps of:
(a) providing a silage material to a livestock feed sorting assembly comprising:
wherein the rotating rods and auger cooperate to transport a silage material at a controlled rate to the intake end of the rotating drum, and
wherein the screen of the rotating drum separates silage material into fines and retentate;
(b) combining the fines into a ration for lactating cows, and
(c) combining the retentate with concentrate to produce a dry cow ration. Optionally, step (c) can comprise combining the retentate with concentrate to produce a ration suitable for young stock.
In some implementations, the conveyance device comprises an auger positioned within the trough, the auger having a first end and a second, free end.
In some implementations, the conveyance device comprises a conveyor positioned within the trough, the conveyor having a first end and a second end. The conveyor can comprise any suitable conveyor apparatus, such as a belt conveyor or chain conveyor.
The hopper can be provided with a fixed, adjustable angle of inclination. In this way, the end user can adjust and set the angle of inclination to thereby control the rate of transport of silage through the hopper and into the sorting unit.
In some implementations, the conveyance device of the hopper can extend from the hopper at an adjustable angle. In these aspects, the hopper can remain at a fixed position, and conveyance device can extend from the hopper toward the sorting unit. The angle of the conveyance device can be adjusted and set to provide a desired rate of transport of silage from the hopper and into the sorting unit.
The one or more rotating rods can include studs that project from the surface. The studs can assist in moving silage downward within the hopper, and toward the conveyance device. In some embodiments, the hopper includes two rotating rods. The rotating rods can be the same or different.
In some aspects, the conveyance device (auger or conveyor) is driven by a force applied to the first end.
In some embodiments, a shaker deck or oscillating deck can be used in substitution for the rotating drum.
Features of inventive methods can include the following. The fines can be combined with corn silage, protein canola, alfalfa, whey permeate, vitamins and minerals to prepare a ration for lactating cows. The retentate can be combined with corn silage, protein canola, alfalfa, whey permeate, vitamins and minerals, to prepare a ration for dry cows and/or young stock.
Animal feed compositions prepared using inventive methods can maintain the palatability and digestibility of the feed, while providing desired nutritional benefits to the animal, as well as significantly reduced cost. Other advantages will be apparent upon review of this disclosure.
The above summary of the present disclosure is not intended to describe each disclosed embodiment or every implementation of the present disclosure. The description that follows more particularly exemplifies illustrative embodiments. In several places throughout the application, guidance is provided through lists of examples, which examples can be used in various combinations. In each instance, the recited list serves only as a representative group and should not be interpreted as an exclusive list.
The disclosure may be more completely understood in consideration of the following detailed description of various embodiments of the disclosure in connection with the accompanying drawings, in which:
The figures are not necessarily to scale. Like numbers used in the figures refer to like components. However, it will be understood that the use of a number to refer to a component in a given figure is not intended to limit the component in another figure labeled with the same number.
In the following description, reference is made to the accompanying set of drawings that form part hereof and in which are shown by way of illustration of specific embodiments. It is to be understood that other embodiments are contemplated and may be made without departing from the scope or spirit of the present disclosure. The following detailed description, therefore, it not to be taken in a limiting sense.
Generally, when referring to the assemblies and methods herein, reference will be made to feed compositions for dairy cattle. In particular, processing of corn silage through a sorting assembly for use in dairy cow rations will be discussed in detail. Corn silage is a popular forage for ruminant animals because it is high in energy and digestibility and is easily adapted to mechanization from the stand-crop to time of feeding.
Such feed compositions for dairy cattle will be utilized to describe inventive concepts, as these applications are useful to highlight features and advantages. However, it will be understood upon review of the present specification that inventive feed sorting assemblies can be adapted for additional uses outside these described illustrative applications.
Inventive concepts provide apparatus and methods of preparing rations for dairy cows and young stock that meet the cows' nutritional needs while maintaining health, and, in lactating cows, optimizing milk production, milk fat and milk protein. Advantageously, inventive concepts provide cost-effective methods to achieve these goals.
Corn silage provides a cost-effective and nutrient dense component for dairy cow rations. However, the corn silage should be properly processed to provide such benefits. When silage is finely comminuted, such small particulate allows good packing density in storage and reduces feed sorting on-site. However, this smaller particle size means that the material will not stay in the rumen long; in these cases, having enough effective fiber to create an adequate rumen mat is important for proper ruminal digestion.
Grain particle size, chop length, and rip and tear of corn plant fibers are factors to consider in order to provide more effective fiber and more digestibility of neutral detergent fiber (NDF). Inventive apparatus and methods herein can be adapted to exploit these factors to achieve beneficial livestock feed rations.
Inventive systems and methods provide ways to take advantage of the corn grain in silage, and enhance feed rations for dairy cows. In illustrative embodiments, corn silage is provided to a sorting assembly that efficiently separates fines from coarse fodder. The fines, a high energy source, can then be formulated with other components to produce a ration for lactating cows. Separately, coarse fodder (retentate) can be combined with corn silage, protein, and other concentrate components to prepare a ration suitable for dry cows and/or young stock. Inventive methods and systems thus provide flexible, enhanced feed rations that can be customized for different populations of dairy cattle.
A livestock feed sorting assembly that is particularly useful for separation of corn silage will now be described with more specificity.
Referring to
The overall configuration of hopper 4 is a container having an upper portion 8 that tapers downward to a trough portion 10 that has smaller dimensions. Upper portion 8 thus defines an intake area 32 that functions to receive corn silage and move that silage downward toward studded rods 28 and auger 12.
Looking more specifically at the interior components of hopper 4 shown in
The embodiment illustrated in
In operation, corn silage is introduced into the top of hopper 4 at the intake area 32. Studded rod(s) 28 rotate to urge the corn silage downward within hopper 4, where auger 12 is located within trough portion 10. The speed with which studded rods 28 rotate can be selected based upon such factors as the type of material being processed, particle size of the material, processing speeds, dimensions of the hopper 4, and the like.
Hopper 4 is provided in a tapered configuration, such that the interior area decreases downward. As illustrated in
As illustrated in
As illustrated in
While
Once the silage has been transported along transport direction 34 to the free end 26 of auger 12, it passes into drum 6. Drum 6 consists of a rolled cylinder of screen having apertures (openings), a length 40 and a diameter 42. The screen can include apertures of a uniform size (all apertures of the screen are the same size, or substantially the same size), or the screen can be composed of apertures that vary in size. In some aspects, the size of the apertures within the screen can be selected depending upon such factors as the amount of retentate to be captured, particle size in the parent material, operating speeds, and the like. It will be appreciated that all dimensions of the components comprising livestock feed sorting assembly 2 can be manipulated depending upon the application of the device.
Drum 6 rotates about an axis 44. The rate of rotation about axis 44 can be adjusted based upon such factors as particle size of material to be processed, desired rate of production, angle at which the drum is positioned, screen aperture size, and the like. Drum 6 acts to separate particles making up the silage composition into size fractions. In use, materials larger than aperture size are trapped above the screen, while particles smaller than the apertures can pass through the screen. The silage composition is thus divided into size fractions comprising fines (smaller particles that pass through the screen) and retentate (larger particles).
Drum 6 is pitched at an angle 38, so that material travelling through the drum is transported by rotation of the drum 6 and gravity. As the material travels through drum 6, smaller particles pass through the screen at 46 and are collected in a collector (not shown). Larger particles (also referred to as retentate) continue through drum 6 and exit the drum 6 at end 50 as shown by arrow 48 to a collector (not shown).
The screen can be provided with any desired aperture diameter to separate the silage by particle size. An illustrative screen size is in a range of about 0.5 inches to about 1 inch, or about 0.6 inches to about 0.9 inches, or about 0.7 inches to about 0.8 inches, such that particles with a size less than the aperture size pass through the screen at 46 and are separated from retentate, which exits drum 6 at the output end 50 shown at arrow 48 to a retentate collector.
Illustrative screen drums can be purchased, for example, from W. S. Tyler, Mentor, Ohio. Drums can be fabricated from metal, such as steel, stainless steel alloys, titanium, Hastelloy, silver, non-ferrous metals, aluminum, phosphor bronze, brass, copper, nickel, Monel, or the like. The fabrication material can be selected based upon such factors as environmental conditions of use (e.g., to avoid corrosion or failure of the part), durability, cost, and dimensional requirements of the drum.
As illustrated in
Dimensions of trough portion 10 are selected to complement conveyor belt 60 or 62 contained within it. Thus, trough portion 10 will typically be provided in a size that is approximate to the diameter of the conveyor belt, to allow the conveyor belt to freely travel therein and move silage in a transport direction 34, while retaining the silage on the conveyor belt until it reaches the sorting unit. Trough portion 10 and conveyor belt 60 or 62 are thus configured to minimize gaps that could allow silage to fall off the conveyor belt, which could reduce processing efficiency and/or clog the equipment. The speed of conveyor 60 or 62 can be varied to control the rate of delivery of silage to the sorting unit (here, drum 6).
In some aspects, shaker deck 70 uses gyratory vibration to separate materials by size. In these aspects, shaker deck 70 is moved in a reciprocating side to side motion at near level plane at low angles. The shaker deck can be set to a shallow angle relative to the horizontal level plane, typically no more than 2 to 5 degrees relative to the horizontal plane. The shaker deck thus travels in an orbital path. In one embodiment, the shaker deck 70 is moved in a reciprocating side to side direction for a distance of about four (4) inches. The rate of movement, as well as dimensions of reciprocating movement, can be adjusted based upon such factors as particle size of material to be processed, desired rate of production, depth 76 of the shaker deck, angle at which the shaker deck is positioned, screen aperture size, and the like. Shaker deck 70 acts to separate particles making up the silage composition into size fractions. In use, material rolls over the screen and falls through the screen apertures with the induction of gravity and directional shifts. In some aspects, the sorting unit can comprise an oscillating deck.
Optionally, rubber balls and trays can provide an additional mechanical means to cause the material to fall through the screen. The balls can also provide a throwing action for the material to find an opening to fall through. Material larger than aperture size is trapped above the screen, while particles smaller than the apertures can pass through the screen. The silage composition is thus divided into size fractions comprising fines (smaller particles that pass through the screen) and retentate (larger particles).
As the material travels across shaker deck 70, smaller particles pass through the screen and are collected in a collector (not shown). Larger particles (also referred to as retentate) continue across shaker deck 70 and exit the shaker deck at a desired point, to a collector (not shown).
The screen can be provided with any desired aperture diameter to separate the silage by particle size. An illustrative aperture size is in a range of about 0.5 inches to about 1 inch, or about 0.6 inches to about 0.9 inches, or about 0.7 inches to about 0.8 inches, such that particles with a size less than the aperture size pass through the screen and are separated from retentate, which exits shaker deck 70 at an output end.
Illustrative shaker decks can be purchased, for example, from BM&M Screening Solutions, Ltd., Surrey, BC, Canada, and Rotex, Cincinnati, Ohio. Shaker screens can be fabricated from metal, such as steel, stainless steel alloys, titanium, Hastelloy, silver, non-ferrous metals, aluminum, phosphor bronze, brass, copper, nickel, Monel, or the like. The fabrication material can be selected based upon such factors as environmental conditions of use (e.g., to avoid corrosion or failure of the part), durability, cost, and dimensional requirements of the shaker deck.
Similar to the embodiment illustrated in
As shown, projections 86 can be positioned at spaced, alternating locations along and around the studded rod 84. Alternative configurations can include projections that protrude at an angle other than 90 degrees, and/or varying the space and/or relative location between individual projections 86. In some embodiments, projections 86 can be provided with uniform dimensions (e.g., diameter and length), so that all projections 86 along a length of studded rod are the same. Alternatively, projections 86 can be provided with varying dimensions (e.g., diameter and/or length), along a length of studded rod, as desired. In some aspects, some or all of the rods 84 can comprise an auger. For example, a portion of a rod 84 can be provided as an auger (i.e., the projection is configured as a continuous spiral around the rod), and another portion of the rod 84 can provide projections 86 in the configurations described elsewhere herein.
In the embodiment shown in
As shown in
Other optional features can include one or more of the following. Drum 6 can include internal fins that protrude from the drum surface toward its interior. These internal fins can be of sufficient dimensions to agitate (e.g., turn or throw) silage as it rotates within the drum. In this manner, the internal fins can increase processing efficiency of the livestock feed sorting assembly. In some aspects, a fan can be included in the livestock feed sorting assembly to blow air through the sorting unit.
The livestock feed sorting assembly 2 can be used to formulate dairy cow rations in a manner that provides an enhanced feed ration, as well as a cost-effective solution to formulating feed. Generally speaking, feed compositions in accordance with inventive concepts include carbohydrates, fiber, and fat. Other additives can include, for example, amino acids, vitamins, minerals, nutraceuticals, pharmaceuticals, and the like. These components will now be described in more detail.
Illustrative primary sources of carbohydrates for livestock feed in accordance with inventive concepts include corn, barley, oats, wheat, sorghum, molasses, beet pulp, and soyhulls. Many dairy farmers grown their own barley, corn, oats, and wheat and will often process these grains to be fed to the cattle. Exemplary corn products include corn silage, corn grain, corn gluten feed, corn germ meal, corn starch, and corn byproducts. Illustrative barley components include barley grain, barley silage, barley byproducts, and the like. Exemplary oat components include oat grain, oat silage, oat byproducts, and the like. Illustrative sorghum components include sorghum grain, sorghum silage, sorghum byproducts and the like. Exemplary wheat components include wheat grain, wheat silage, wheat bran, red dog wheat, wheat germ, wheat flour, wheat middlings, wheat byproducts and the like.
Molasses, beet pulp and soyhulls can be purchased from a feed mill. Depending upon the nutritional requirements of the cows, a farmer can select one or more of these carbohydrate sources to complement the forage.
Other carbohydrates include isolated dry or wet milled starch, bakery byproducts, hominy feed, peas, brewers' grains, distillers' grains, malt sprouts, rice, rice bran, rice flour, other rice byproducts, cereal feed, and tubers such as potatoes, yams, sweet potatoes, cassava (tapioca) and arrow root.
Combinations of any two or more of these carbohydrates may be used, as desired.
The amount of carbohydrate in the ration can be in a range of about 2 weight percent (wt.-%) to about 40 wt.-%.
Fiber in the form of neutral detergent fiber (NDF) can be included in the ration in an amount in the range of about 50 wt.-% to about 24 wt.-%. Other suitable fiber includes crude fiber, and acid detergent fiber (ADF).
Exemplary primary sources of protein include protein canola, canola meal, distillers' grains, soybean meal, corn gluten meal, and cottonseed meal.
Other proteinaceous sources include other oil seed meals such as palm meal; animal by-product meals such as meat meal, poultry meal, blood meal, feather meal and fishmeal; plant by-product meals such as wheat middlings, soybean hulls and corn by-products; and microbial protein such as torula yeast and brew's yeast.
The amount of protein content in the ration can vary. Generally, the protein content in the ration is in a range of about 12 wt.-% to about 19 wt.-%.
Feed compositions can also include added fat. Added fat can be used to support intake, rumen development, digestion, and optimal growth. “Added fat” includes edible mono-, di- and triglycerides of fatty acids and free fatty acids that are not inherently present in the starch source, protein source or any other nonfat source present in the feed composition. Added fat includes both animal fat (such as tallow, beef tallow, choice white grease, yellow grease, and the like), as well as plant oils.
Illustrative primary added fat sources include vegetable oil (such as soybean oil), palm oil, cottonseed oil, sunflower oil, tallow, fish oil, and protected fatty acids. Other suitable fats include those that contain palmitic acid (such as palm stearin), stearic acid, lauric acid, myristic acid, coco butter and any hydrogenated fat or oil.
Optionally, one or more minerals and vitamins can be included in inventive livestock feed rations. These nutrients can be balanced depending upon the needs of the cows. Exemplary primary sources include calcium, phosphorus, magnesium, sodium, chloride, potassium, sulfur, iron, zinc, manganese, copper, cobalt, iodine, selenium, vitamin A, D, E, and some B-vitamins. In some embodiments, prebiotics and/or probiotics can be used to aid in digestion and support the health of the cows.
Other optional additives include flavorings, coloring and dye ingredients, nutraceuticals and pharmaceuticals, and processing aids. Illustrative processing aids include talc and calcium carbonate. Illustrative flavorings include amino acids, molasses, and the like.
Feed compositions in accordance with inventive concepts can be provided as daily feed ration for a variety of livestock animals. The livestock animals can include domesticated animals such as dairy cows, beef cattle, sheep, goats, deer, horses, and the like. Inventive livestock feed sorting assemblies and methods can also be used to provide feed compositions for zoo animals.
In some aspects, inventive concepts provide methods of preparing a livestock feed ration, the method comprising steps of:
(a) providing a silage material to a livestock feed sorting assembly that comprises
wherein the rotating rods and conveyance device cooperate to transport a silage material at a controlled rate to the intake end of the rotating drum, and
wherein the screen of the rotating drum separates silage material into fines and retentate;
