Resumo: | The experiment was conducted at the Núcleo de Produção Animal (Nupran) of the Universidade Estadual do Centro Oeste do Paraná (Unicentro). The trial aimed to evaluate the effect of particle size (small: between 0.2 and 0.6 cm or large: between 1 and 2 cm) and cutting height (low cut: 15.2 cm or high cut: 38.6 cm) of corn plant for silage on the behavior of confined steers. The treatments were: TPB – small particle size with low cut height; TGB – large particle size with low cut height; TPA – small particle size with high cut height; and TGA – large particle size with high cut height. The roughage:concentrate ratio was 62.7%:37.3%. No significant difference was detected among treatments for the time spent by the animals on feed consumption activity (4.19; 4.03; 4.13 and 4.01 h, respectively). Significant interaction between cutting height and particle size was observed for the time spent with rumination. For the silage with high cutting the time spent with rumination was significantly higher for the large particle size (9.47 h) in relation to the small particle size (7.98 h), however, for the low cutting the difference between the large particle size (9.04 h) and the small particle size (8.73 h) was not significant.KEY WORDS: Animal behavior, free time, particle separator, rumination time, selectivity. |

A relação volumoso:concentrado foi de 62,7%:37,3%. Não se detectou diferença significativa entre os tratamentos no tempo gasto pelos animais na atividade de consumo alimentar (4,19; 4,03; 4,13 e 4,01 h, respectivamente). Houve interação significativa entre altura de colheita e tamanho de partículas para a atividade de ruminação. Nas silagens de corte alto o tempo gasto com ruminação foi significativamente maior para partículas grandes (9,47 h) em relação às partículas pequenas (7,98 h), porém, no corte baixo, a diferença entre partículas grandes (9,04 h) e pequenas (8,73 h) não foi significativa.PALAVRAS-CHAVES: Capacidade de seleção, comportamento animal, separador de partículas, tempo de ruminação, tempo de ócio.Universidade Federal de Goiás2009-07-02info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionAvaliado por parespesquisa científicaapplication/pdfhttps://revistas.ufg.br/vet/article/view/298710.5216/cab.v10i2.2987Brazilian Animal Science/ Ciência Animal Brasileira; Vol. 10 No. 2 (2009); 462-473Ciência Animal Brasileira / Brazilian Animal Science; v. 10 n. 2 (2009); 462-4731809-68911518-2797reponame:Ciência animal brasileira (Online)instname:Universidade Federal de Goiás (UFG)instacron:UFGporhttps://revistas.ufg.br/vet/article/view/2987/4835Neumann, MikaelRestle, JoãoMühlbach, Paulo Roberto Frenzel FrenzelNörnberg, José LaerteRomano, Marco AurélioLustosa, Sebastião Brasil Camposinfo:eu-repo/semantics/openAccess2009-07-03T14:37:09Zoai:ojs.revistas.ufg.br:article/2987Revistahttps://revistas.ufg.br/vetPUBhttps://revistas.ufg.br/vet/oai||revistacab@gmail.com1809-68911518-2797opendoar:2024-05-21T19:55:04.874384Ciência animal brasileira (Online) - Universidade Federal de Goiás (UFG)true |
