What does a refined bone structure in breeding gilts indicate?

A refined bone structure in breeding gilts is often indicative of lower fat content. Animals with a refined bone structure typically have a more streamlined physique, which is associated with a higher muscle-to-fat ratio. This is important in the context of meat production, where a desirable trait is the ability to produce meat with a leaner composition.

A gilt with a refined bone structure is more likely to have efficient growth rates and better feed conversion ratios, which contribute to healthier and more desirable meat traits. Additionally, a leaner animal often results in a higher yield of marketable meat while maintaining a desirable level of carcass quality. This emphasis on lower fat content aligns with market demands for healthier meat options, making it a crucial trait for breeders focused on producing quality livestock.
