Um dos objetivos do Projeto de Desenvolvimento de Germoplasma de Mandioca para as condições semi-áridas do Nordeste do Brasil, desenvolvido pela Embrapa Mandioca e Fruticultura, em parceria com o IPA e o CIAT e financiado pelo Fundo Internacional para o Desenvolvimento da Agricultura (IFAD), foi aumentar a diversidade genética de mandioca utilizada sob as condições semi-áridas, que permita contribuir para a sustentabilidade do sistema de produção de mandioca sob essas condições. Para atender essa demanda foram avaliados 1000 genótipos do Banco de Germoplasma de Mandioca da Embrapa Mandioca e Fruticultura e gerados milhares de híbridos em Cruz das Almas, Bahia.Todo esse material foi avaliado na base experimental do IPA em Araripina-PE, no período compreendido entre 1991 a 1999. Nos anos de 1999 a 2002 os clones selecionados foram avaliados em provas participativas com agricultores de vários municípios do semi-árido do Nordeste. |

The effects of divergent phenotypic classification in crossbreed Holstein × Gyr dairy heifers for methane emissions in relation to performance, digestibility, energy and nitrogen partition, blood metabolites and temperature of body surface were evaluated. Thirty-five heifers were classified as high and low emission for CH4 production (g/day), yield (g/kg dry matter intake) and intensity (g/kg average daily gain). Digestibility was evaluated by total collection of feces and urine. Gas exchanges were obtained in open-circuit respiratory chambers. A completely randomized design was used and divergent groups were compared by Fisher's test. No differences were found in intake traits between groups of CH4 production and intensity. The low yield group had higher intake. For digestibility and temperature at different body sites were no differences between variables. High production group had higher energy losses as methane and heat production. Low intensity group had higher digestible energy, energy balance and ratio between metabolizable and digestible energy. Urinary nitrogen was 14.3% lower for low production group. There was a difference between methane yield divergent groups for nitrogen intake, digestible and retained. Energy and nitrogen partitioning traits are correlated to the animals divergent for methane production and yield. The low production group presented lower blood insulin concentration. It was not possible to identify divergent animals for CH4 emission using the infrared thermography technique.
