A method for comprehensive evaluation of duck egg quality

Abstract

The invention discloses a method for comprehensive evaluation of the quality of duck eggs, which uses principal component analysis to conduct large-scale measurements on the properties of duck egg weight, egg shape index, eggshell strength, Haugh unit, iron content, zinc content and human essential amino acid content. Multi-indicator comprehensive evaluation and weight coefficient determination are carried out on the above seven trait indexes, and the principal component comprehensive evaluation model Y=Azx is established. 1 -Bzx 2 +Czx 3 +Dzx 4 +Ezx 5 ‑Fzx 6 +Gzx 7 , where: zx1, zx2, zx3, zx4, zx5, zx6, zx7 respectively represent the measured values ​​of standardized egg weight, egg shape index, eggshell strength, Haugh unit, iron content, zinc content and human essential amino acid content; For different varieties of duck eggs, the above indicators are actually inspected, and the comprehensive scores of egg quality of different duck varieties are calculated through the above formulas, and sorted according to the comprehensive scores to determine the quality of eggs of different varieties. The invention effectively solves the technical problem that it is difficult to evaluate the quality of eggs, provides effective technical support for breeding high-quality duck eggs and consumers choose duck eggs, and has good application prospects.

Description

technical field [0001] The invention relates to a method for comprehensive evaluation of duck egg quality, belonging to the technical field of duck egg quality evaluation. Background technique [0002] Duck eggs are rich in nutrients such as amino acids and minerals, and are very popular among consumers. However, the determination of duck egg quality is limited to the determination of conventional egg quality indicators (egg weight, egg shape index, eggshell thickness, Haugh unit, etc.), and few studies involve the determination of duck egg nutrients. Han Peng et al. analyzed the egg quality traits and crude protein, crude fat, calcium, phosphorus, The content of nutrients such as zinc and iron was determined (Han Peng et al., Determination of egg quality and nutritional components of silk-wrapped duck eggs, China Animal Husbandry and Veterinary Medicine, 2013 (7): 192-194), and it was found that one or several traits in a variety were relatively low. Good, while other tra...

However, the determination of duck egg quality is limited to the determination of conventional egg quality indicators (egg weight, egg shape index, eggshell thickness, Haugh unit, etc.), and few studies involve the determination of duck egg nutrients.

Han Peng et al. analyzed the egg quality traits and crude protein, crude fat, calcium, phosphorus, The content of nutrients such as zinc and iron was determined (Han Peng et al., Determination of egg quality and nutritional components of silk-wrapped duck eggs, China Animal Husbandry and Veterinary Medicine, 2013 (7): 192-194), and it was found that one or several traits in a variety were relatively low. Good, while other traits are poor, and there are often contradictory results between unit traits, so it is difficult to comprehensively evaluate the quality of duck eggs of different breeds

The key is that egg quality is a comprehensive trait, and the weight of each unit trait is difficult to scientifically determine, resulting in the inability to effectively evaluate the egg quality of different duck breeds.
