Abstract: 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.

Abstract: The present disclosure provides a molecular marker for identifying traits of efficiency of duck feed utilization based on a neuropeptide gene NPY, a method and use thereof. The NPY gene has a nucleotide sequence shown in SEQ ID NO: 1, the molecular marker is T or C, and the molecular marker is located at position 577 of the nucleotide sequence. In the present disclosure, mutation of the NPY gene is detected using a polymerase chain reaction-single strand conformation polymorphism (PCR-SSCP) method, the traits of efficiency of duck feed utilization are selected based on genotypes, and a breeding method for early selection of efficiency of poultry feed utilization is established. The method is simple, rapid, and low-cost, does not need special instrument, and satisfies experimental needs.
