Peanut cake as a substitute for soybean meal in the diet of goats.

Abstract: This study aimed to test the hypothesis that peanut cake can substitute for soybean meal in the feed of ruminants on the basis of the intake, performance, digestion, and serum urea and glucose concentration in crossbred Boer × indigenous goat kids. Forty intact vaccinated and dewormed crossbred Boer × indigenous goat kids (average age = 5 mo, average BW = 15.6 ± 2.7 kg) were used. The goats were fed Tifton-85 (Cynodon dactylon) hay and concentrate mixes of corn bran, soybean meal, premix mineral, and peanut cake substituted for soybean meal at rates of 0.0%, 33.33%, 66.67%, and 100%. The animals were confined for 62 d, and the digestibility trial was performed from d 27 to 31 of confinement. Samples of orts and feces were quantified and collected from each animal during this period. On the d 32 of confinement, a blood sample was taken from animals to measure urea N and glucose. Data were analyzed with a regression model. Substitution of soybean meal with peanut cake in the diet of the animals resulted in a reduction in intake of DM (P = 0.02), CP (P = 0.03), NDF (P = 0.03), nonfiber carbohydrate (NFC; P = 0.01), and TDN (P = 0.02) and an increase in intake of ether extract (P < 0.001). The total and daily average weight gains decreased (P = 0.02) with substitution, whereas G:F was not influenced (P = 0.11). With the exception of ether extract digestibility, which increased (P < 0.001) with substitution, digestibility of DM (P = 0.13), OM (P = 0.18), CP (P = 0.54), NDF (P = 0.20), and NFC (P = 0.73) was not influenced by diets. The concentration of serum urea N was influenced quadratically by the postprandial time for treatments with 33.33%, 66.67%, and 100.00% substitution. Peanut cake is not a complete, equal substitute for soybean meal in goat feed. However, peanut cake may represent an eventual replacer able to reduce goat producers’ dependence on traditional ingredients in the feed of growing goat kids.

A história de vida focal e suas potencialidades na pesquisa em saúde e em enfermagem

Abstract: The objective of this report is to show up our experience in using Focal Life Story strategy as a methodological attacking for researchs that tyed to apprehend the getting illness experience impact and the care search by the Brazilian Health Unique System users, showing its nursing and health research potentialities and at health services evalutive practices. The narratives richness came up the users subjectivity, as well as their interpretations and the meanings during this process, helping us at the deep comprehention of this experience, that others methodos probably would not offer us. The Focal Life Story allowed us to build the Therapeutics Itineraries tackled by the users when looking for resolutivity for their health necessities, and demonstrated a huge potencial as a privileged methodological strategy for the health services evalutive practices trough the view from who live the getting illness and the care search, that is, the health system user and his family.

Rarity of monodominance in hyperdiverse Amazonian forests

Abstract: Tropical forests are known for their high diversity. Yet, forest patches do occur in the tropics where a single tree species is dominant. Such "monodominant" forests are known from all of the main tropical regions. For Amazonia, we sampled the occurrence of monodominance in a massive, basin-wide database of forest-inventory plots from the Amazon Tree Diversity Network (ATDN). Utilizing a simple defining metric of at least half of the trees ≥ 10 cm diameter belonging to one species, we found only a few occurrences of monodominance in Amazonia, and the phenomenon was not significantly linked to previously hypothesized life history traits such wood density, seed mass, ectomycorrhizal associations, or Rhizobium nodulation. In our analysis, coppicing (the formation of sprouts at the base of the tree or on roots) was the only trait significantly linked to monodominance. While at specific locales coppicing or ectomycorrhizal associations may confer a considerable advantage to a tree species and lead to its monodominance, very few species have these traits. Mining of the ATDN dataset suggests that monodominance is quite rare in Amazonia, and may be linked primarily to edaphic factors.
