A decoy adapter stand allows a floatable buoyant waterfowl decoy to be adapted for use on land. The decoy adapter stand includes an upper securing bracket, a base, and a vertical spacer joining the upper bracket to the base. The securing bracket is used to secure a floatable buoyant waterfowl decoy to the stand, and the base provides a stable support. In use, the vertical spacer distances the decoy from the surface of the ground, so that the decoy appears to be standing. A first, freestanding embodiment of the decoy adapter stand includes a footed base. A second embodiment of the decoy adapter stand includes a staked base, where portions of the base are insertable into the ground. A method of using the described apparatus to adapt a floatable buoyant decoy for land use is also described.

A device to repel and disperse waterfowl entering a proscribed area consists of a laser beam generator generating a laser beam, and a photoelectric switch is provided so that the inventive device is only activated from dusk to dawn. A motion sensor senses the presence of waterfowl and activates the light beam source that is aimed into the area. In the preferred embodiment, a timer is provided that may be set for a desired duration. When the desired duration has elapsed, the controller deactivates the light beam source. The light beam source may consist of a single laser beam or a multiplicity of laser beams shining into the protected area. In one preferred embodiment of the present invention, a single laser beam is split into a plurality or multiplicity of beams using a suitable beam splitter. The inventive device may be equipped with a system that enables one or more laser beams to sweep and oscillate through the protected area so that not only is full coverage of the area assured, but the elevation of the beams is at least, at some points in time, at the level of the eyes of the waterfowl so that the waterfowl can detect the presence of the laser beams and quickly flee the area.

A realistic looking waterfowl decoy has repositionable head and body portions to enable members of a group of decoys to be placed in a variety of positions to mimic a resting flock of real birds, for example, geese. At least portions of the bodies, as well as the necks and heads, of the decoys can have faux feathers adhered to their surfaces to more accurately simulate real waterfowl. A preferred embodiment of the decoy assembly has oblate spheroid end portions formed on attachment portions of both the legs and a keel member which allow the decoy assembly to be alternatively adapted for use both on land and in the water.

The invention provides a preparation method of attenuated goose astrovirus and a live vaccine prepared by applying the attenuated goose astrovirus, and belongs to the technical field of waterfowl disease prevention and control. A method combining high-temperature treatment and low-temperature incubation is adopted to attenuate the virus. The method has the advantages of short virus attenuation time, low cost and long immune protection time. There is virulence return after multiple passages, thus effectively preventing goose gout disease caused by goose astrovirus.

The invention relates to a duck viral hepatitis and duck reovirus disease bivalent inactivated vaccine and a preparation method thereof. According to the invention, based on the epidemic situation ofmixed infection of duck reovirus and duck hepatitis virus in domestic waterfowl epidemic diseases, an effective coping strategy is provided, wherein separated domestic epidemic strains of a duck reovirus 17117 strain, a duck hepatitis virus type 1 16115 strain and a duck hepatitis virus type 3 16023 strain are used as vaccine preparation strains, and antigen solution preparating, inactivating, concentrating and mixing according to a certain ratio is performed to prepare the duck viral hepatitis and duck reovirus disease bivalent inactivated vaccine; and in the application of the duck viral hepatitis and duck reovirus disease bivalent inactivated vaccine, currently epidemic type 1 and type 3 duck viral hepatitis and duck reovirus diseases can be simultaneously and effectively prevented after one immunization with the vaccine.

The present invention is a decoy system that simulates waterfowl taking off and landing byway of a string, pulley and spring which collectively cause a crossbeam holding waterfowl decoys to raise and lower relative to the surface of the water in which the system sits. When the string is pulled one end of the crossbeam holding one decoy lowers and the opposite end of the beam holding either a counterweight or another decoy raises. When the string is released a spring attached to the opposite side of the beam from the string moves the beam towards its original position and thereby the string and spring actuate a teetering motion that provides a visual que on both sides of the hinge at the midpoint of the crossbeam.

A first portion and a second portion of a decoy where the first portion is weighted or weightable and the second portion is buoyant. A housing attached to the first portion of the decoy by a hinge. An actuator combined to the housing engages the first portion of the decoy to selectively raise and lower the first portion of the decoy into the water.

The invention discloses a special multivitamin immunopolysaccharide microemulsion preparation for waterfowl. Each 1050 parts of the special multivitamin immunopolysaccharide microemulsion preparation for the waterfowl by weight comprises a traditional Chinese medicinal extract, 51.11-102.52 parts of multivitamin, 25.5-51.5 parts of polysaccharide and 12.5-25 parts of sunflower seed oil by weight, wherein the traditional Chinese medicinal extract is obtained by performing alcohol extraction on the following traditional Chinese medicinal raw materials in parts by weight: 200-250 parts of honeysuckle, 350-400 parts of radix bupleuri, 400-450 parts of indigowoad leaf, 150-200 parts of rheum officinale, 100-150 parts of motherwort, 100-150 parts of radix gentianae and 60-80 parts of liquorice. The invention aims to provide the special multivitamin immunopolysaccharide microemulsion preparation for the waterfowl, which can quickly supplement nutrition, resist diseases and promote growth. The invention also aims to provide a preparation method and specific application of the special multivitamin immunopolysaccharide microemulsion preparation for the waterfowl.

A weight retraction device for use with a waterfowl decoy includes a housing having a spool rotatably coupled thereto. A weight is attached to a line that is wound around the spool. Rotation of the spool in a first rotational direction causing an unwinding of the line from the spool to cause the weight to extend away from the housing while rotation of the spool in a second rotational direction causing a rewinding of the line back onto the spool to cause the weight to retract back towards the housing. A power spring is configured to urge the spool to rotate in the second rotational direction. A lock release mechanism is configured to normally be in a locked configuration for preventing an undesired rotation of the spool in the second rotational direction. A manual actuation of the lock release mechanism releases the locked configuration of the lock release mechanism.

The invention discloses a real-time fluorescent quantitative PCR (Polymerase Chain Reaction) primer group for visual detection on infection conditions of duck circovirus (DuCV) and goose circovirus (GoCV) and a method thereof. According to the method, the detection on the infection conditions of DuCV and GoCV is carried out by using dissolution curve temperature Tm value difference caused by the difference between nucleotide GC contents of DuCV and GoCV specific gene fragment regions amplified by primers, and the infection conditions of DuCV and GoCV can be subjected to visual differential diagnosis specifically by only combining the SYBR Green I based real-time fluorescent quantitative PCR primer group to difference of dissolution curve Tm values which are automatically generated after reaction is ended. The method disclosed by the invention is simple and is relatively high in efficiency and accuracy.
