Resumo: The study was carried out to evaluate the milk production potential of ‘Mott’ elephantgrass pastureduring january-april/2000 in Alto Vale do Itajaí, Santa Catarina. The free stall used in the farm was the control production system. The grazing cows were fed with 10kg of dry matter of leaf blade/100kg LW/day of forage in daily strip pasture. The free stall dairy cows were fed with a diet based on corn silage, industrial by-products, forage and concentrate with 23kg/day of dry matter intake. The stocking rate sustained for ‘Mott’ elephantgrass pasture was1.415kg LW/ha with individual production of 11,4kg milk/day, resulting in an milk potencial production of 7.000kg/ha during 200 grazing days. The free stall cows produced 17,3kg milk/cow. Differences were found in milk fat content with mean values of 3,85% and 3,42% for grazing and free stall cows, respectively. The free stall cows had highermastitis incidence and milk somatic cell contents three times greater than grazing cows. The grazing system reduced feed cost and increased return per cow.

No período de janeiro a abril de 2000 foi conduzido um experimento no Alto Vale do Itajaí, SC, com o objetivo de avaliar o potencial de produção de leite em pastagem de capim-elefante-anão, tendo como referência comparativa o sistema de produção em semiconfinamento. As vacas em pastejo receberam uma oferta de forragem de 10kg de matéria seca (MS) de lâminas verdes/100kg de peso vivo (PV)/dia, pastejando em faixas diárias. As vacas em semiconfinamento receberam uma dieta composta por silagem de milho, resíduos industriais, forragens picadas, ração balanceada e acesso limitado a pastagens, consumindo em média 23kg de MS/dia, além de pastagem de capim-elefante-anão,que sustentou uma carga animal média de 1.415kg de PV/ha com rendimentos individuais de 11,4kg de leite/dia, resultando numa produção de 7.000kg de leite/ha, considerando um período potencial de utilização de 200dias. As vacas em semiconfinamento tiveram uma produção média de 17,3kg de leite/vaca/dia. A composição do leite somente se diferenciou no teor de gordura, com valores de 3,85% e 3,42% para o lote em pastejo e confinado,respectivamente. As vacas em semiconfinamento apresentaram maior incidência de mastite, com valores de contagem de células somáticas no leite três vezes maiores que os registrados nas vacas em pastejo. Vacas pastejandocapim-elefante-anão tiveram um custo de alimentação de apenas 23,3% em relação às vacas semiconfinadas, o que possibilitou um maior retorno por vaca.Empresa de Pesquisa Agropecuária e Extensão Rural de Santa Catarina - Epagri2021-07-28info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://publicacoes.epagri.sc.gov.br/rac/article/view/1007Agropecuária Catarinense Journal; Vol. 17 No. 2 (2004); 80-83Agropecuária Catarinense; v. 17 n. 2 (2004); 80-832525-60760103-0779reponame: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/1007/904Copyright (c) 2004 Agropecuaria catarinensehttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessde Almeida, Edison XavierBaade, Elena Apezteguía Setelich 2021-07-28T17:17:00Zoai:ojs.publicacoes.epagri.sc.gov.br:article/1007Revistahttps://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:2021-07-28T17:17Agropecuária Catarinense (Online) - Empresa de Pesquisa Agropecuária e Extensão Rural de Santa Catarina (Epagri)false
