The objectives of this study were to investigate trends based on daily measurements of feeding behavior traits in Duroc barrows during growth, and to investigate phenotypic correlations between feeding length and feeding rate, and feeding frequency, ADFI, G:F, growth rate, and rate of fat deposition. The data set of the current study was not sufficiently large for accurate estimation of heritabilities and genetic correlations. Knowledge on genetic parameters is needed in order to further discuss the possibility of incorporating feeding length and feeding rate in the
selection objectives. However, results of the current study indicate that, when sufficiently heritable, feeding length and feeding rate may be used to improve feed intake capacity in pigs during growth.
