Does blade action indicate muscling and leanness?

Blade action is an indicator of muscling in livestock, particularly in cattle and swine. When observing blade action, which refers to the movement and definition of the shoulder blades during motion, one can assess the animal's muscle development. A pronounced blade action typically suggests that the animal has a greater amount of muscle mass, particularly in the shoulder region, which is linked to overall body condition and leanness.

Animals with good muscling will show strong, defined blade action when they walk or run, reflecting their physical strength and efficiency. This is significant for producers and evaluators because a well-muscled animal can contribute to better meat quality and yield more product upon processing. Therefore, recognizing blade action as a factor in evaluating livestock can lead to better breeding and selection decisions aimed at improving muscling and leanness in herds.

While the other choices suggest varying conditions or limitations to this indicator, generally, blade action consistently relates to the overall assessment of an animal's muscularity and body composition.
