Feed samples received by commercial analytical laboratories are often undefined or mixed varieties of forages, originate from various agronomic or geographical areas of the world, are mixtures (e.g., total mixed rations) and are often described incompletely or not at all. Six unified single equation approaches to predict the metabolizable energy (ME) value of feeds determined in sheep fed at maintenance ME intake were evaluated utilizing 78 individual feeds representing 17 different forages, grains, protein meals and by-product feedstuffs. The predictive approaches evaluated were two each from National Research Council [National Research Council (NRC), Nutrient Requirements of Dairy Cattle, seventh revised ed. National Academy Press, Washington, DC, USA, 2001], University of California at Davis (UC Davis) and ADAS (Stratford, UK). Slopes and intercepts for the two ADAS approaches that utilized in vitro digestibility of organic matter and either measured gross energy (GE), or a prediction of GE from component assays, and one UC Davis approach, based upon in vitro gas production and some component assays, differed from both unity and zero, respectively, while this was not the case for the two NRC and one UC Davis approach. However, within these latter three approaches, the goodness of fit (r(2)) increased from the NRC approach utilizing lignin (0.61) to the NRC approach utilizing 48 h in vitro digestion of neutral detergent fibre (NDF:0.72) and to the UC Davis approach utilizing a 30 h in vitro digestion of NDF (0.84). The reason for the difference between the precision of the NRC procedures was the failure of assayed lignin values to accurately predict 48 h in vitro digestion of NDF. However, differences among the six predictive approaches in the number of supporting assays, and their costs, as well as that the NRC approach is actually three related equations requiring categorical description of feeds (making them unsuitable for mixed feeds) while the ADAS and UC Davis approaches are single equations, suggests that the procedure of choice will vary dependent Upon local conditions, specific objectives and the feedstuffs to be evaluated. In contrast to the evaluation of the procedures among feedstuffs, no procedure was able to consistently discriminate the ME values of individual feeds within feedstuffs determined in vivo, suggesting that the quest for an accurate and precise ME predictive approach among and within feeds, may remain to be identified.

Este estudo analisa o Ensino Superior Agrcola Brasileiro ESAB, como campo (Bourdieu, 1983a), diante do cenrio do mundo cambiante em que vivemos, com os seguintes objetivos: (i) resgatar parte da histria, destacando dois momentos de inflexo vividos pelo ESAB: o primeiro a partir da dcada de 1960, quando, dentro do projeto urbano-industrialista, foram lanadas as bases do conhecimento e das estruturas acadmicas (ainda hegemnicos) para a modernizao da agricultura. O segundo na virada do Sculo XX, quando existe uma multiplicidade de propostas e no h mais um modelo a ser copiado; (ii) sugerir alguns dos caminhos possveis e suas implicaes para as instituies do ESAB, que pretendam encontrar novo sentido social no seu trabalho; (iii) analisar a influncia das Universidades Norte-americanas no ESAB, tendo em vista sua importncia no perodo de 60 e como essa influncia se manifesta no segundo momento. Um college norte-americano (College of Agricultural and Environmental Science da University of California Davis) e uma faculdade brasileira (Faculdade de Agronomia da UFRGS) foram escolhidos, como centros de formao e de pesquisa importantes e com participao destacada nos intercmbios bilaterais. Essas instituies servem como testemunhas exemplares da dinmica geral. Em ambas foram realizadas investigaes e foram ouvidos atores destacados (professores-pesquisadores), atravs de questionrios e entrevistas ao vivo Nas duas universidades os professores mostraram-se conscientes sobre as mudanas em curso, mas na UFRGS parece que o debate est menos desenvolvido. Diante das tendncias que se apresentam, a Agricultura Sustentvel e a Biotecnologia foram eleitas como plos aglutinadores de diferentes projetos em disputa no incio do Milnio. O estudo conclui que ou as escolas de agronomia se modificam ou no se justificam e tambm que, as mudanas podem ou no se vincular busca de uma ruptura paradigmtica (Santos, 1997). Conclui ainda, que seria importante cada instituio explicitar sua proposta, mesmo que esta seja de convivncia entre os diferentes projetos. Finalmente opina que, Agricultura Sustentvel parece ser estrategicamente mais interessante; tendo em vista ser mais adequada realidade social e ambiental do Brasil.
