"The average daily gains of Czech Pied bulls (dual-purpose, Simmental type) were analyzed using single-trait animal models, a multi-trait animal model and random regression models. The herd-year-season classes (HYS) were created and season was defined as 3-month class starting with December. Legendre polynomials were used to describe daily gains within the HYS classes and to model bull-specific gain curves. The results showed that polynomials of at least the 2nd degree are to be used for the genetic analysis of daily gains."@en . .
