    • Feeding behavior of finishing pigs under diurnal cyclic heat stress 

      Oliveira, Marllon José Karpeggiane de; Valk, Márcio; Melo, Antônio Diego Brandão; Marçal, Danilo Alves; Silva, Cleslei Alisson; Valini, Graziela Alves da Cunha; Arnaut, Pedro Righetti; Gonçalves, Joseane Penteado Rosa; Andretta, Ines; Hauschild, Luciano (2023) [Artigo de periódico]
      The impact of cyclic heat stress (CHS) and turning the lights on and off on pig feeding behavior (FB) was investigated. The FB of 90 gilts was recorded in real-time under two ambient temperatures (AT): thermoneutrality ...

    • Genetic selection modulates feeding behavior of group-housed pigs exposed to daily cyclic high ambient temperatures 

      Fraga, Alícia Zem; Hauschild, Luciano; Campos, Paulo Henrique Reis Furtado; Valk, Márcio; Bello, Débora Zava; Silva, Marcos Kipper da; Andretta, Ines (2022) [Artigo de periódico]
      This study was conducted to evaluate the effect of genetic selection (Lines A and B; Line A pigs have a greater proportion of Pietrain genes than those from Line B and therefore, selected for improved lean tissue accretion) ...

    • Prandial correlations and structure of the ingestive behavior of pigs in precision feeding programs 

      Gomes, Bruna Cristina Kuhn; Andretta, Ines; Valk, Márcio; Pomar, Candido; Hauschild, Luciano; Fraga, Alícia Zem; Silva, Marcos Kipper da; Trevizan, Luciano; Remus, Aline (2021) [Artigo de periódico]
      The feeding behavior of growing-finishing pigs was analyzed to study prandial correlations and the probability of starting a new feeding event. The data were collected in real-time based on 157,632 visits by a group of 70 ...
