Resumo: Agrosilvopastoral system is a type of production that involves the soil-forage-animal interface, both of which are benefited by the system. Hence, the present study evaluated the effects of agrosilvopastoral system on the quantitative and qualitative characteristics from pasture, and the animal performance during the feeding period of Nellore heifers. The treatments included: Soil-forage-animal – 357 eucalyptus trees per hectare (LFA14x2m); Soil-forage-animal – 227 eucalyptus trees per hectare (LFA22x2m); and Soil-animal – Five native trees remaining per hectare (CON). The forage used was Brachiaria brizantha cv. BRS Piatã and having as trees planted the Eucalyptus urograndis clones H 13. Treatment effects (P <0.05) for forage accumulation and pasture height, which were lowest in LFA14x2m compared to the others. Total forage dry mass in CON treatment was significantly greater (P <0.05) compared to the other treatments, showing maximum production in March. The LFA14x2m treatment was favorable for greater forage quality, showing an effect on chemical composition (P <0.05), compared to other treatments. Whereas, in November the LFA22x2m treatment was better for neutral detergent fiber. January and March, the treatments were similar (P >0.05) for average daily gain, while in November period, LFA14x2m treatment showed the lowest value (P <0.05). The lowest weight gain by area (November) occurred in the LFA14x2m treatment (P <0.05), although in March the LFA14x2m treatment stocking rate was similar to the others. Forage production and animal performance are altered by the trees densification in agrosilvopastoral systems. The chemical composition of pasture is better in systems with a higher trees density.

Así, el presente estudio evaluó los efectos de los sistemas agrosilvopastoriles sobre las características cuantitativas y cualitativas del pasto y el rendimiento animal durante el período de alimentación de las novillas Nelore. Los tratamientos incluyeron: Suelo-forraje-animal- 357 eucaliptos por hectárea (LFA14x2m); Suelo-forraje-animal- 227 eucaliptos por hectárea (LFA22x2m); y Animal-suelo - 5 árboles nativos restantes por hectárea (CON). El forraje utilizado fue Brachiaria brizantha cv. BRS Piatã y los árboles plantados fueron clones H 13 de Eucalyptus urograndis. Los efectos del tratamiento (P<0,05) para la acumulación de forraje y la altura del pasto fueron menores para LFA14x2m en comparación con los otros. La masa seca total de forraje en el tratamiento CON fue significativamente mayor (P<0,05) en comparación con los otros tratamientos, presentando su máxima producción en marzo. El tratamiento LFA14x2m fue favorable para una mayor calidad de forraje, mostrando un efecto sobre la composición química (P<0,05), en comparación con otros tratamientos. En noviembre, el tratamiento LFA22x2m fue mejor para la fibra detergente neutra. En enero y marzo, los tratamientos fueron similares (P>0,05) para la ganancia diaria promedio, mientras que, en noviembre, el tratamiento LFA14x2m tuvo el valor más bajo (P<0,05). La menor ganancia de peso por área (noviembre) ocurrió en el tratamiento LFA14x2m (P<0,05), aunque en marzo la carga ganadera del tratamiento LFA14x2m fue similar a las demás. La producción de forrajes y el rendimiento animal se ven alterados por la densificación de los árboles en los sistemas agrosilvopastoriles. La composición química del pasto es mejor en sistemas con mayor densidad de árboles.O sistema agrossilvopastoril é um tipo de produção que envolve a interface solo-forragem-animal, ambos beneficiados pelo sistema. Assim, o presente estudo avaliou os efeitos de sistemas agrossilvopastoris sob as características quantitativas e qualitativas da pastagem e o desempenho animal durante o período de alimentação de novilhas Nelore. Os tratamentos incluíram: Solo-forragem-animal - 357 eucaliptos por hectare (LFA14x2m); Solo-forragem-animal - 227 eucaliptos por hectare (LFA22x2m); e Animal-solo - 5 árvores nativas remanescentes por hectare (CON). A forragem utilizada foi Brachiaria brizantha cv. BRS Piatã e as árvores plantadas foram clones H 13 de Eucalyptus urograndis. Efeitos de tratamento (P<0,05) para acúmulo de forragem e altura do pasto, foram menores para LFA14x2m em relação aos demais. A massa seca total da forragem no tratamento CON foi significativamente maior (P<0,05) em relação aos demais tratamentos, apresentando máxima produção no mês de março. O tratamento LFA14x2m foi favorável para maior qualidade da forragem, apresentando efeito para a composição química (P<0,05), comparado aos outros tratamentos. Enquanto que, em novembro o tratamento LFA22x2m foi melhor para a fibra em detergente neutro. Em janeiro e março, os tratamentos foram semelhantes (P>0,05) para ganho médio diário, enquanto no período de novembro, o tratamento LFA14x2m apresentou o menor valor (P<0,05). O menor ganho de peso por área (novembro) ocorreu no tratamento LFA14X2m (P<0,05), embora no mês de março a taxa de lotação do tratamento LFA14x2m tenha sido similar aos demais. A produção de forragem e o desempenho animal são alterados pelo adensamento de árvores em sistemas agrossilvopastoris. A composição química da pastagem é melhor em sistemas com maior densidade de árvores.Research, Society and Development2020-10-04info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/864310.33448/rsd-v9i10.8643Research, Society and Development; Vol. 9 No. 10; e4729108643Research, Society and Development; Vol. 9 Núm. 10; e4729108643Research, Society and Development; v. 9 n. 10; e47291086432525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIenghttps://rsdjournal.org/index.php/rsd/article/view/8643/7820Copyright (c) 2020 Jeskarlândia Silva Barros; Kennyson Alves de Souza; Fabiana Villa Alves; Roberto Giolo de Almeida; Ossival Lobato Ribeiro; Adriana Regina Bagaldo; Daniele Rebouças Santana Loureshttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessBarros, Jeskarlândia Silva Souza, Kennyson Alves de Alves, Fabiana Villa Almeida, Roberto Giolo de Ribeiro, Ossival Lobato Bagaldo, Adriana Regina Loures, Daniele Rebouças Santana 2020-10-31T12:03:23Zoai:ojs.pkp.sfu.ca:article/8643Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:31:04.648774Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false

Total forage dry mass in CON treatment was significantly greater (P <0.05) compared to the other treatments, showing maximum production in March. The LFA14x2m treatment was favorable for greater forage quality, showing an effect on chemical composition (P <0.05), compared to other treatments. Whereas, in November the LFA22x2m treatment was better for neutral detergent fiber. January and March, the treatments were similar (P >0.05) for average daily gain, while in November period, LFA14x2m treatment showed the lowest value (P <0.05). The lowest weight gain by area (November) occurred in the LFA14x2m treatment (P <0.05), although in March the LFA14x2m treatment stocking rate was similar to the others. Forage production and animal performance are altered by the trees densification in agrosilvopastoral systems. The chemical composition of pasture is better in systems with a higher trees density.
