    摘要: A welfare-oriented raising house for meat-type ducks, including a raising house, is provided. The raising house is internally provided with a support frame which is of a U-shaped structure and arranged in a length direction of the raising house, a raising net arranged at a top of the support frame, a cleaning and storing mechanism arranged at one end of the support frame for cleaning and storing the raising net, a traction mechanism arranged at the other end of the support frame for the traction of the raising net, blocking mechanisms which are of a zigzag structure and arranged at both sides of the support frame, and tensioning vibration mechanisms arranged at bottoms of the blocking mechanisms and fixedly connected to a side edge of the support frame.

    摘要: Differential illumination systems and methods selectively provide light having different spectrums in an aviary system for housing animals located within an enclosure, and in the enclosure. A first light source produces light with a first spectrum, and illuminates an internal volume of the aviary system. A second light source produces light with a second spectrum different from the first spectrum, and illuminates the enclosure outside of the aviary system. The first spectrum can have a higher red component than the second spectrum to encourage chicken to lay eggs inside of the aviary system, and the second spectrum can have a higher blue component than the first spectrum to discourage chicken from laying eggs outside of the aviary system.

    摘要: Various apparatus and associated methods involve a light source that provides light at wavelengths that substantially correlate to local maxima in the spectral sensitivity of a diurnal avian. In an illustrative example, the light source may output light primarily in wavelength bands that are not substantially absorbed by colored oil droplets and/or visual pigment in at least one type of cone in the eye of a diurnal avian. In some embodiments, the light source may include a light-emitting diode (LED) light source. Exemplary light sources may output spectral components to illuminate diurnal avians with local maxima of intensity at wavelengths that substantially correspond to local maxima in a spectral sensitivity visual response characteristic of the diurnal avians.

    摘要: A solar air heating curtain for installation on the wall or eave of a building consisting of a sheet of flexible translucent or transparent film facing outward from the building and a sheet of flexible film facing inward toward the building with both films joined around the perimeter forming an interior air volume, with a flexible air permeable material, that is heated when exposed to solar energy, suspended between the films, and a fan to move air from outside; through an air inlet, through the interior air volume in close contact with the air permeable material, and through an air outlet.
