Comprehensive estimation of overfeeding influence on goose meat quality

Area of Science:

• Animal Science
• Food Science
• Poultry Production

Background:

• Foie gras production traditionally involves force-feeding ducks or geese.
• Understanding the impact of overfeeding on meat quality is crucial for optimizing production and consumer value.

Purpose of the Study:

• To investigate the effects of overfeeding on the meat quality of Tianfu Meat Geese.
• To analyze changes in physical, nutritional, and fatty acid profiles of goose meat post-overfeeding.

Main Methods:

• Comparative study involving a normal-feeding control group and an overfeeding (force-feeding) group.
• Meat quality analysis including physical attributes (color, hardness, cooking loss), nutritional composition (crude fat, amino acids), and fatty acid profiles.
• Statistical analyses including cluster analysis, principal component analysis (PCA), and partial least square-discriminate analysis (PL-SDA).

Main Results:

• Overfeeding significantly increased breast and leg muscle weights, L*, a*, b* values, and hardness.
• Cooking loss in breast muscle decreased, while crude fat content increased in both breast and leg muscles.
• Significant alterations in amino acid profiles and fatty acid composition were observed in both muscle types, with PCA and PLS-DA confirming the influence of overfeeding.

Conclusions:

• Overfeeding positively impacts key meat quality parameters in Tianfu Meat Geese.
• The study provides comprehensive data on the effects of force-feeding on goose meat characteristics, relevant to foie gras production.
