Embodiment 1

[0066] A phoenix-tailed chicken from Heishui County, Aba Prefecture, Sichuan Province, obtained through multi-element content determination, multiple comparative analysis, principal component analysis, systematic clustering analysis and discriminant analysis:

[0067] The discriminant analysis model of the content of Mn, Cs and Ag in the phoenix-tailed chicken and the content of Mn, Cs and Ag in the white feather chicken is:

[0068] Model 1 (A) = -86.261+0.199Mn+0.370Ag-0.552Cs

[0069] Model 2(B)=-15.283+0.059Mn+0.367Cs+0.088Ag

[0070] Model 3(C)=-20.251+0.017Mn+0.995Cs-0.005Ag

[0071] Model 4 (D) = -36.722-0.018Mn+1.589Cs-0.062Ag

[0072] Among them, models 1-4 represent chicken thigh samples, chicken breast samples, white chicken legs and white chicken breast samples.

[0073] Specifically in the application process:

[0074] Take sample chicken legs and sample chicken breasts, as well as white feather chicken legs and white feather chicken breasts, and detect the contents of Mn, Cs ...

Embodiment 2

[0085] A phoenix-tailed chicken produced in Heishui County, Aba Prefecture, Sichuan Province, said multi-element content determination, multiple comparative analysis, principal component analysis, systematic clustering analysis and discriminant analysis comprising the following method steps:

[0086] A. Take chicken samples of Phoenix-tail chicken and white chicken chicken;

[0087] B. Determine the types and contents of elements in chicken chicken samples and white chicken chicken samples;

[0088] C. Obtain the types and contents of two kinds of chicken's trace elements from step B, and then perform multiple comparative analysis to obtain the types of trace elements with significant differences in content in the two chickens, and preliminarily infer that these significantly different trace elements can be applied In the tracing of the Phoenix tail chicken;

[0089] D. Use principal component analysis and systematic clustering to further analyze the trace elements that can be applied...

Embodiment 3

[0093] 1. Types of amino acids tested and sample description

[0094] Detection of aspartic acid, threonine, serine, glutamic acid, proline, glycine, alanine, cystine, valine, methionine, isoleucine, leucine, tyrosine in chickens The content of eighteen kinds of amino acid, phenylalanine, histidine, lysine, and arginine were compared with those of the commercially available white feather chickens. The sample description is as follows:

[0095] Chicken thighs of phoenix-tailed chicken are marked as: S1, S2, S3; breasts of phoenix-tailed chicken are marked as S4, S5, S6; a total of 6 samples; white-feathered chicken legs are marked as: C1, C2, C3; commercially available The breast meat of white feather chickens were marked as C4, C5, and C6; there were 6 samples in total, and 12 samples of the two breeds of chickens.

[0096] 2. Testing methods and data analysis reference standards

[0097] The determination method of amino acid content in Phoenix chicken is based on GB / T5009.124-2016...

Abstract

The invention relates to a Fengwei chicken produced in a Sichuan province Aba prefecture Heishui country and belongs to the technical field of poultry. The Mn, Cs and Ag content in the Fengwei chickenand the Mn, Cs and Ag content in a white-feather chicken are obtained through multi-element content determination, multiple-comparison analysis, principal component analysis, analysis based on a hierarchical clustering method and discriminant analysis, and a discriminant analysis model is established. The problem is solved that the variety and geographical origin traceability standards of the Fengwei chicken cannot be determined by adopting the method in the prior art. The variety and origin place of the Fengwei chicken produced in the Sichuan province Aba prefecture Heishui country can be determined by utilizing the discriminant analysis model and the trace element content.

Description

Technical field [0001] The present invention relates to a chicken from a specific place of production. More specifically, the present invention relates to a chicken with a tail from Heishui County, Aba Prefecture, Sichuan Province, and belongs to the technical field of poultry. Background technique [0002] Phoenix-tailed chicken is a kind of Tibetan chicken. It has strong foraging and flying ability. It is suitable for grazing and free-range breeding. It is a characteristic product of Heishui County, Aba Prefecture, Sichuan Province. The special ecological environment of the plateau breeds rich and unique species. Resources. Heishui County is a semi-agricultural and semi-pastoral county. It is located in the high mountain and gorge area of ​​the Western Sichuan Plateau and the central part of the Aba Tibetan and Qiang Autonomous Prefecture. It is located in the middle of the Minshan Mountains. It is dominated by plateaus, alpine valleys and Zhongshan river valleys, with an alti...
