A Method for Determining the Optimum Market Age of Meat Ducks

Abstract

The invention discloses a method for determining the optimal market age of meat ducks through a duck muscle quality comprehensive evaluation system, which provides effective technical support for the breeding of high-quality meat ducks and the selection of duck meat for consumers. The present invention systematically measures multiple market-aged conventional duck meat quality indexes (breast muscle protein, breast muscle fat) and duck nutrient substance indexes (Fe, Zn, Ca, Mg, flavor amino acids, essential amino acids, cholesterol, polyunsaturated fatty acids, etc.) ), using the principal component analysis method to carry out multi-indicator comprehensive evaluation and weight coefficient determination on the above-mentioned 10 trait indexes, and establish a principal component comprehensive evaluation model Y=0.3178zx 1 ‑0.2532zx 2 ‑0.0277zx 3 ‑0.2250zx 4 ‑0.2402zx 5 +0.3192zx 6 +0.3112zx 7 +0.3079zx 8 ‑0.2489zx 9 +0.2953zx 10 , which can reflect the comprehensive level of duck meat quality to the greatest extent, and can be effectively used to judge the optimal slaughtering age of meat ducks.

Description

technical field [0001] The invention relates to a method for determining the optimal market age of meat ducks, belonging to the technical field of poultry breeding. Background technique [0002] Duck meat is rich in nutrients such as amino acids and minerals. It has a unique flavor and delicious meat quality. It is a healthy meat that is deeply loved by consumers. The quality of duck meat is not only affected by factors such as breed, feeding environment and method, and feed nutrition level, but also the age at market is also one of the important factors affecting the quality of duck meat. Studies have shown that the biochemical reactions in the body of ducks of the same species will change with the extension of the breeding date, which will lead to changes in the types and contents of taste substances and nutrients in the muscles, and finally result in the meat quality of ducks slaughtered at different ages. There are differences. [0003] In poultry research, Liu Chunli ...

Problems solved by technology

[0005] Purpose of the invention: In view of the current low accuracy of judging the optimal slaughtering age of meat ducks by evaluating a certain unit trait in muscle quality, it is difficult to find the optimal slaughtering age of meat quality, and often contradictory results occur, However, it is difficult to determine the weight of each trait by using multiple unit traits to evaluate one by one. The present invention uses the principal component analysis method to carry out multi-index comprehensive evaluation and weight coefficient on the basis of systematically measuring multiple market-aged meat quality indicators. Confirmed, established a comprehensive evaluation model of duck meat quality at different ages, which can be effectively used to judge the optimal age of meat ducks
