Title A name given to the resource Produtividade e valor nutritivo de pasto de capim-elefante manejado sob princípios agroecológicos Productivity and nutritive value of an elephantgrass pasture managed under agro-ecologic principles Creator An entity primarily responsible for making the resource Pablo Santini Charão, Clair Jorge Olivo, Gilmar Meinerz, Lilian Elgalise Techio Pereira, Magnos Fernando Ziech, Denise Tyska Description An account of the resource Objetivou-se avaliar o valor nutritivo do capim-elefante, quanto aos teores de PB e FDN e a digestibilidade in vitro da MS (DIVMS), submetido a algumas práticas agroecológicas. Foram usados dois piquetes (0,15 ha cada), onde foi estabelecido o capim-elefante, em 2001, com espaçamento entrelinhas de três metros. Nas entrelinhas, estabeleceram-se aveia (Avena strigosa Schreb.) e azevém (Lolium multiflorum Lam.) no período hibernal e, no estival, permitiu-se o desenvolvimento de espécies de crescimento espontâneo. A adubação foi feita com fertilizantes orgânicos (150 kg de N /ha). No período experimental (24/04/2004 a 05/05/2005), foram conduzidos sete pastejos. Os animais experimentais foram vacas da raça Holandesa que receberam, como complementação alimentar, 3,5 kg/dia de concentrado. Avaliaram-se a massa de forragem inicial, composição botânica do pasto e os componentes estruturais. Para as análises de valor nutritivo do pasto, foram feitas amostragens simulando o pastejo. O delineamento experimental foi de blocos ao acaso com duas repetições (piquetes) e sete tratamentos (pastejos). Os melhores resultados do valor nutritivo foram obtidos no período hibernal. Foram encontradas correlações negativas da PB e DIVMS e positivas da FDN com a biomassa de lâminas foliares do capim-elefante. O capim-elefante, manejado sob princípios agroecológicos, apresentou alto valor nutritivo e produtividade, tanto no verão quanto no inverno, possibilitando que a produção animal seja mais sustentável no decorrer do ano.The objective of this work was to evaluate forage nutritive value by determining the crude protein (CP), neutral detergent fiber (NDF), and in vitro dry matter digestibility (IVDMD) from forage submitted to some agro-ecologic practices. Two paddocks, each one with 0.15 ha, were used in the evaluation. The elephantgrass was planted in 2001, spaced 3 m between rows. Mixture of oat and ryegrass during the winter period and spontaneous growing species in the summer period has been planted/left between the rows. It was applied organic fertilizer in the rate of 150 kg/ha of N. Seven grazing cycles were carried out during the experimental period from 04/24/2004 to 05/05/2005. Holstein cows receiving 3.5 kg/daily complementary concentrate feed were used in the evaluation. The initial forage mass, the botanical composition, and the structural components of elephantgrass pastures were evaluated. Hand-plucked samples were collected to analyze the nutritive value. The experimental design utilized was randomized blocks, with two replicates (paddocks) and seven treatments (grazings along the time). The best results for nutritive value were found during the winter period. Negative correlations between CP with IVDMD and positive between NDF with elephantgrass leaf lamina biomass were found. The elephantgrass pasture, managed under agro-ecologic principles, showed high nutritional value and productivity, both during the summer and during the winter, making the animal production more sustainable along the year.
