Reproductive efficiency is a performance trait highly correlated to femininity.

Reproductive efficiency is indeed considered a performance trait that is closely linked to femininity, particularly in livestock such as cattle. This connection arises because animals that exhibit greater femininity are often more capable of successful reproduction, which includes factors such as ease of calving, milk production for sustaining offspring, and overall fertility.

Femininity in livestock can be characterized by certain physical traits, such as a more refined structure and a body condition that supports the demands of reproduction. A highly feminine animal is typically more productive in terms of offspring raised and successful breeding cycles, which translates to efficient reproductive performance.

In contrast, traits typically associated with masculinity may not support optimal reproductive outcomes in female livestock. Understanding this relationship helps breeders select animals that not only meet aesthetic criteria but also excel in reproductive capabilities, ultimately improving the productivity of their herd. This emphasizes the importance of considering appearance alongside performance traits when making selection decisions in livestock breeding.
