The quality of beef is influenced by what factors of the animal?

1. Breed and environment

2. Weight and age

3. Breed and age

4. Size and shape

The correct answer is: Breed and age

The quality of beef is significantly influenced by the breed and age of the animal. Breed determines the genetic traits that affect muscle development, fat distribution, and flavor profile, which are all essential characteristics of the meat. For instance, certain breeds are known for producing higher-quality meat with better marbling (the intramuscular fat that enhances flavor and tenderness), while others may yield leaner cuts. Age also plays a crucial role in meat quality. Generally, younger animals produce more tender meat because the muscle fibers have not had as much time to develop toughness. As animals age, the muscle fibers become denser, and the connective tissue may become tougher as well, impacting the overall tenderness and quality of the beef. While factors such as weight can correlate with age and development, and environmental conditions can affect animal health and growth, the specific combination of breed and age is most directly associated with the inherent quality attributes of the beef produced. Therefore, breed and age stand out as the key factors influencing beef quality.
