Abstract

The invention relates to a duck sebum character living body prediction method and application thereof. The method comprises the following steps: feeding a batch of ducklings in stages, recording the weight and feed intake of each duck in each stage, calculating the residual feed intake and feed conversion rate of each duck after the feeding is completed, obtaining a body size index and a serum biochemical index of each duck, selecting a batch of ducks from the bred ducks as a to-be-detected group, slaughtering the ducks to obtain sebum traits of the ducks in the to-be-detected group, calculating a multiple linear regression equation of the sebum traits of the ducks by using statistical analysis software, and predicting the residual group sebum traits of the raised ducks by using the multiple linear regression equation. According to the method, the sebum traits of the live ducks can be quickly and accurately estimated, the elimination probability of excellent individuals in breeding is greatly reduced, and the breeding efficiency is greatly improved.

Description

technical field

[0001] The invention relates to the technical field of production and breeding of Peking ducks; in particular, it relates to a method for in vivo prediction of duck sebum traits and an application thereof. Background technique

[0002] The sebum trait is an important trait in Peking duck breeding, and it is also the characteristic of Peking duck. Higher sebum deposition is the key to making Peking duck with crispy skin and rich aroma. Therefore, the sebum trait has always been the key selection trait in the Peking duck breeding work, and the sebum weight and sebum rate are generally used as the breeding indicators.

[0003] In the long-term breeding work, sibling selection based on slaughter determination is the most traditional determination method for sebum traits selection, but there are very big disadvantages: slaughtering live bodies brings a huge workload to the breeding work, is time-consuming and laborious, and at the same time will lose part of the g...
