Resumo: This trial aimed to assess animal performance and production in a mixture pasture of black oat and annual ryegrass in an integrated crop-livestock system by means of a 2x2 factorial experiment replicated in three randomized blocks. The plots consisted of two canopy heights (10 and 25cm) kept by continuous grazing and submitted to two-nitrogen fertilization (NP – nitrogen applied on pasture in autumn time; and NG – nitrogen applied on corn crop in springtime). The total amount of nutrients applied over the year was the same for all treatments. Forage nutritive value, herbage allowance, forage mass, and pasture carrying capacity increased with nitrogen application (urea – 45% N) on pasture, with no effect on animal performance, resulting in higher animal production per area. Lower sward canopy height led to lower forage mass, longer grazing diurnal time, and shorter rumination diurnal time.

O delineamento experimental utilizado foi o de blocos ao acaso em esquema fatorial (2x2), com três repetições. Os fatores foram duas alturas do pasto (10 e 25cm) mantidas sob pastejo com lotação contínua e taxa de lotação variável, além de passarem por duas épocas de adubação nitrogenada no sistema (NP – adubação nitrogenada feita na pastagem, no outono e NG – adubação nitrogenada feita na lavoura - cultura de grãos). A quantidade total de nutrientes aplicados por ano foi a mesma para todos os tratamentos. A aplicação do nitrogênio (ureia – 45% N) na pastagem indicou aumento no valor nutritivo, oferta e massa de forragem, assim como na capacidade de suporte, sem alterar o desempenho animal, resultando em maior produção animal por unidade de área. A menor altura de dossel condicionou menor massa de forragem, maior tempo diurno de pastejo e menor tempo diurno de ruminação.Empresa de Pesquisa Agropecuária e Extensão Rural de Santa Catarina - Epagri2021-12-28info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://publicacoes.epagri.sc.gov.br/rac/article/view/124810.52945/rac.v34i3.1248Agropecuária Catarinense Journal; Vol. 34 No. 3 (2021); 76-81Agropecuária Catarinense; v. 34 n. 3 (2021); 76-812525-60760103-0779reponame:Agropecuária Catarinense (Online)instname:Empresa de Pesquisa Agropecuária e Extensão Rural de Santa Catarina (Epagri)instacron:EPAGRIporhttps://publicacoes.epagri.sc.gov.br/rac/article/view/1248/1225Copyright (c) 2021 Denise Adelaide Gomes Elejalde, André Brugnara Soares, Regis Luis Missio, Tangriani Simioni Assmann, Angela Bernardonhttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessElejalde, Denise Adelaide GomesBrugnara Soares, André Missio, Regis Luis Assmann, Tangriani Simioni Bernardon, Angela Zatta, Angélica Caroline 2022-06-22T11:42:32Zoai:ojs.publicacoes.epagri.sc.gov.br:article/1248Revistahttps://publicacoes.epagri.sc.gov.br/RAC/indexPUBhttps://publicacoes.epagri.sc.gov.br/index.php/RAC/oaieditoriarac@epagri.sc.gov.br || lamperuch@epagri.sc.gov.br2525-60760103-0779opendoar:2022-06-22T11:42:32Agropecuária Catarinense (Online) - Empresa de Pesquisa Agropecuária e Extensão Rural de Santa Catarina (Epagri)false
