Analyzing milk quality using a microeconomic multi-output model: The role of genetics

Antonio Álvarez, Carlos Arias, David Roibás

Abstract

In this paper we analyze the influence of genetics on milk quality. For that purpose, we use a multi-output production model in which milk quality is included as an additional output in milk production. A distance function is used to estimate empirically the contribution of genetics to milk quality. For that purpose, we use a panel data of 96 dairy farms in Asturias. This dataset contains indexes measuring the genetic traits of the herd.
