The disclosure generally relates to spray applicators for dosing vaccines and/or administering probiotics to caged avian animals. In particular, the disclosure relates to spray applicators having improved acceptance by the avian animals, relative to more disruptive prior spray applicators. The disclosed automated caged spray applicator system is designed to attach to and function with automated poultry feeding systems.
Current spray application for caged birds requires the operator to either push a cart with an attached tank, or, carry a backpack tank filled with compositions, including vaccine compositions, and walk at a controlled speed to evenly distribute the compositions to the caged birds. Both methods rely on a “mast and nozzle system,” which distributes the nozzles in such a way that they are roughly aligned with each cage tier, to optimize the application of vaccine to each bird in the cage. These methods are not without significant drawbacks. For example, the operator must push the cart (or walk with the pack) at an optimum and consistent speed, both to ensure that the birds receive a full dose, and to minimize waste. As such, distribution, efficacy, and cost-effectiveness largely depend upon how quickly and consistently each person passes through a given poultry house, leading to significant and costly farm to farm variation.
Another drawback to current spray systems stems from the variation in poultry cage design. For example, some cages are not completely vertical, but are instead more pyramidal in shape. In this case, the vertical mast of the current sprayer systems is not optimally compatible, leading to waste and reduced vaccine efficacy. As a consequence of this incompatible geometry, the cages closer to the bottom are much closer to the spray nozzles, such that the cages on higher rows receive less vaccine than the cages on lower rows. Some of the cages at the highest levels do not even receive vaccine, which becomes particularly problematic at new facilities having more than eight levels of cages. In addition, the birds often become frightened by the current systems, and move the rear of the cages, thus increasing waste and reducing effective vaccination. And while the cart system is workable, it is bulky and can become cumbersome and difficult to move between houses and farms that have stairs, doorways, rough surfaces, and the like. Finally, the space between cages where the cart must be pushed differs among houses/farms, and there are some farms where the path is not level.
Accordingly, there is a real need in the poultry industry for improved spray vaccinators, which do not suffer from the drawbacks mentioned above. The field requires a spray vaccinator for caged birds having improved efficacy and reduced waste.
The automated caged bird spray applicator would be provided as a versatile kit, which can be attached to an automated caged bird feeding apparatus, and easily transported to and from the poultry houses. Such an automated system eliminates the variability inherent in the current “human-powered” caged bird spray vaccinators.
Further, since the birds are already accustomed to the automated feeder, and in fact, welcome its presence, the automated caged bird spray applicator will be far less likely to cause the birds to retreat to the back of the cages.
An object of the current invention is to provide an automated caged bird spray applicator system for delivering compositions, including vaccine compositions, to caged avian animals. In particular, the disclosure relates to spray applicators having improved acceptance by the avian animals, relative to more disruptive prior art spray vaccinators. The disclosed automated caged spray applicator system is designed to attach to and function with automated feeding systems.
In an embodiment, the spray applicator system is provided as a compact portable system comprising nozzles, which mount directly onto an automated feeder system via industrial grade magnets and adjustable nozzle retaining means, including holders, for optimum spray coverage. The movement of the feeder system along the rows of cages provides consistent spray application and dosage by controlled speed of travel.
In an embodiment, nozzles may be positioned in optimal proximity and direction, with respect to the birds, irrespective of the placement, orientation, or arrangement of the cages.
In a particular embodiment, birds that have moved to front of the cage to feed will now be vaccinated at the same time, thereby increasing the likelihood that a given bird will receive an effective dose of vaccine.
In one embodiment of the spray applicator system, the system comprises a composition-containing bag or reservoir, a pump, a battery, a pressure regulator, a pressure gauge, a battery meter, nozzles, means for securing/attaching nozzles to an automated feeder system, and all necessary tubing for carrying fluid from the composition-containing bag to the pump and from the pump to the spray nozzle. The system may include a portable case, which may house, contain or store all the above-recited system components. The nozzle securing means may comprise a pivot arm, to provide a full range of motion to accommodate various mounting angles. The nozzle securing means may comprise a strong magnet, operably connected to the nozzle.
In another embodiment, the composition bag may be reversibly attached and/or suspended from the automated feeder. The nozzles may be placed at appropriate positions along the feeder such that vaccine is optimally directed toward the birds.
A full and enabling disclosure of the present invention, including the best mode thereof, to one of ordinary skill in the art, is set forth more particularly in the remainder of the specification, including reference to the accompanying figures, wherein:
The present invention relates to an automated caged bird spray applicator system, which is adapted to work with automated poultry house feeding systems, also known as feed trolleys.
In an embodiment, the disclosure provides an automated caged bird spray applicator system comprising a composition reservoir in the form of a back pack, along with a hand-held case which houses a pump, a regulator, a pressure gauge, a battery, a battery level indicator, an on/off switch and necessary plumbing. The case may also serve as a storage and transportation unit for the nozzles and associated plumbing/tubing.
In a second aspect, the disclosure provides a method for using the spray applicator system. In an embodiment, a system operator places the backpack directly on a preexisting automated poultry feeder system. The backpack reservoir may be filled with vaccine or other compositions, including probiotic compositions, prior to being carried to the house or filled after the bag is reversibly affixed to the feeder system.
In another embodiment, the operator opens the hand-held case, removes the nozzle assemblies and magnetically mounts said nozzle assemblies in appropriate locations of the feeder system, such that the direction of the nozzles may be adjusted to optimally deliver vaccine to the birds. Adjustment of the nozzles may be accomplished by moving the multi-positioning arm of said nozzle assembly and locking it into a position. The skilled person using the disclosed spray applicator will understand how to position and direct the nozzle to maximize the amount of vaccine, or other composition, including a probiotic formulations, that is delivered to the birds.
In one embodiment, the nozzles are positioned such that they spray vaccine directly at each cage as the feeder moves along rows of cages. In this position, the nozzles will optimally deliver vaccine whether the birds are feeding from the feed track, or whether the birds are in the rearmost portion of the cage. Wherever the birds are in their cages, the nozzles effectively deliver composition to the key target areas of the birds: the eyes, nostrils and mouths.
Once the nozzles are positioned on the feeder, optimally directed toward the cages, and locked into position, the operator may engage the feeder system and activate the spray applicator system. In an embodiment, the operator may adjust the pressure according to the speed of the feeder. As the feeder moves along the track, the birds move toward the front of the cage to feed by a learned habit known as memory trace. In in a particular embodiment, the birds are simultaneously sprayed in the target areas by the optimally-positioned nozzles, delivering and optimally amount of vaccine or other composition per unit time.
The Automated Caged Bird Spray Applicator is ideally suited for cage systems that use automatic feeders or trolleys. It provides for optimal spray nozzle placement and for precise dosage regulation. There is currently no other such device on the market.
Referring now in more detail to the drawings, in which like numerals indicate like parts throughout the several views,
As indicated in
Now that this disclosure has been made, the skilled person will appreciate many routine variations to the nozzle assembly 100. For example, instead of two pivot balls 104, 116 reversibly lockable by the action of clamp 106, screw cap 105 and screw anchor 108, nozzle body 111 could be attached to nozzle assembly base 119 via reversibly lockable hinges or other suitable reversible locking means. Other functional equivalents are envisioned, provided that their structures allow for the nozzle to be positioned in a plurality of directions, to deliver the spray of liquid formulation to a desired locations.
The spray applicator system also comprises a portable pump system 200. A representative example of the pump is shown in
Moreover, the spray applicator system comprises a portable backpack system 300 comprising a tank/reservoir 310. As illustrated in

4) mounting the portable pump system 200, the backpack assembly 300 and the nozzle assemblies 100 to an automated poultry feeding apparatus 400;
5) adjusting the pump 210 pressure to provide a formulation flow rate that is appropriate for the speed of the feeding apparatus;
6) allowing the feeding apparatus to move along the tiers of caged birds; and
7) switching the pump system 200 from a recirculation mode to a dispense mode, wherein when the pump system 200 is in the dispense mode, the formulation flows from the pump system 200, through the outlet 206, through conduit 600, and finally out of the nozzle assemblies 100. The foregoing steps may be completed in any reasonable order.
