Preferentse

Preferentse is a term used in the context of animal breeding, particularly in the dairy industry. It refers to a system of genetic evaluation that aims to identify and reward breeding animals that consistently pass on desirable traits to their offspring. The goal of preferentse breeding is to accelerate genetic progress within a herd or population by focusing on animals that demonstrate superior breeding values over a significant number of progeny.

This system often involves rigorous data collection and analysis, tracking various performance indicators such as milk yield, milk composition, udder health, fertility, and longevity. Animals that are classified as "preferent" have shown a statistically significant and consistent superiority in these traits across a large sample of their offspring. This classification is not a one-time event but rather an ongoing evaluation based on accumulating performance data.

The preferentse system encourages breeders to select and mate animals that have proven their genetic worth. By prioritizing preferent sires and dams, farmers can improve the overall genetic merit of their herd more efficiently than through traditional selection methods. This can lead to increased profitability and sustainability in the long run, as animals with superior traits are often more productive and healthier. The concept aims to distinguish truly exceptional breeding animals from those that are merely average or moderately good, thereby driving more impactful genetic improvement.
