Comprehensive identifying method for day-age of Runzhou crested white duck

Abstract

The invention discloses a comprehensive identifying method for a day-age of a Runzhou crested white duck, and belongs to the technical field of animal husbandry. The comprehensive identifying method comprises the steps that corresponding indexes of a duck day-age such as main muscular tissue, apparatuses and skeletons are selected, correlation analysis is carried out by using SPSS, Curve Expert 2.6 is applied to fit a curvilinear model, and at last an optimal curvilinear model and an identifying scheme are determined. The comprehensive identifying method for the day-age of the Runzhou crestedwhite duck can play a promoting action on a superior meat duck industry through precise identification of the day-age of the Runzhou crested white duck. On the one hand, the inaccuracy and the limitation of a traditional judging method for the day-age of the duck through body appearance are changed; and on the other hand, stability of a meat duck market is maintained, parts of unscrupulous merchants are prevented form mixing the false with the genuine to save the cost, and consumers can obtain superior products.

Description

technical field [0001] The invention relates to a method for comprehensive identification of the age of the crested white duck in Runzhou, belonging to the technical field of animal husbandry. Background technique [0002] Runzhou crested white duck is the only domestic ornamental and medicinal genetic resource formed by Yangzhou University and Zhenjiang Tiancheng Agricultural Technology Co., Ltd. after more than 10 years of work. Runzhou crested white duck is characterized by black beak, white feathers and crested head. It is rich in trace elements selenium and glutamic acid. Its unique meat flavor and rich nutrition are favored by consumers.

[0003] At present, there are many studies on the quality of high-quality duck meat, but there is a lack of unified evaluation standards, resulting in mixed products in the market, which seriously hinders the development of high-quality duck industry represented by crested white duck

Generally speaking, high-quality ducks grow slowly compared to larger meat ducks, and the breeding cycle is long. Only ducks that meet a certain breeding age can have better flavor and taste; however, it is difficult for consumers to accurately determine the real age of ducks only by physical characteristics Therefore, it is necessary to establish a new method to accurately identify the age of high-quality ducks, so as to achieve "the unity of high-quality products and high-end value" and ensure the healthy development of the high-quality duck industry
