On-Farm and Processing Factors Affecting Rabbit Carcass and Meat Quality Attributes.

Area of Science:

• Animal Science
• Food Science
• Nutritional Science

Background:

• Rabbit meat is nutritionally rich, with favorable omega-3 fatty acids and low fat, cholesterol, and sodium compared to beef, pork, and poultry.
• Despite its health benefits, rabbit meat consumption remains low, potentially due to limited understanding of factors influencing its quality.
• Quality attributes are influenced by genetics, environment, diet, rearing, and processing, with breed and muscle type being key but understudied factors.

Purpose of the Study:

• To review the determinants of rabbit meat quality, focusing on the impact of different breeds and muscle types.
• To consolidate information on nutritional composition, carcass, and meat quality attributes influenced by breed and muscle variations.
• To highlight the biological activities of rabbit meat proteins, such as angiotensin-converting enzyme inhibitory and antioxidant properties.

Main Methods:

• Literature review synthesizing existing research on rabbit meat quality.
• Analysis of factors affecting nutritional and physicochemical properties, including breed and muscle anatomical location.
• Compilation of data on health benefits and biological activities associated with rabbit meat consumption.

Main Results:

• Rabbit meat's nutritional profile is influenced by breed and muscle type, affecting fatty acid composition, intramuscular fat, cholesterol, and sodium content.
• Variations in rabbit breeds and muscle locations significantly impact carcass yield and meat quality parameters.
• Rabbit meat proteins demonstrate beneficial angiotensin-converting enzyme inhibitory and antioxidant activities.

Conclusions:

• Breed and muscle type are critical determinants of rabbit meat's nutritional and quality attributes.
• Further research and clear information on these factors are essential for optimizing rabbit production and processing.
• Highlighting the health benefits and unique properties of rabbit meat can improve consumer satisfaction and market acceptance.
