Animal production from new Panicum maximum genotypes in the Amazon biome Brazil

摘要

The Panicum maximum breeding program coordinated by Brazilian Agricultural Research Corporation - Embrapa hsbeen evaluating and selecting genotypes under different fland climatic conditions, with the objective to release cultivars adapted to the diverse regions of Brazil. For Amazon biome, small-plot experiments carried out in ibetween 2003 and 2005 allowed the selection of some sing genotypes (Valentim and Andrade 2005; metal. 2006; Andrade and Valentim 2009), with potential for forage growth than cultivars on the narket. The objective of this work was to compare 2 new P. maximum genotypes with cv. Tanzania in relation to orrying capacity and animal performance, when managed der rotational stocking in the Amazon biome.
