Isolamento e seleção inicial de rizóbios obtidos de solos de Mato Grosso do Sul para inoculação em feijoeiro (Phaseolus vulgaris L.)

Este estudo tem como objetivo a formação de um banco de germoplasma de rizóbio e a seleção de estirpes mais eficientes e adaptadas às condições locais para inoculação em feijoeiro. Os ensaios foram conduzidos na Embrapa Agropecuária Oeste e constou de experimentos de laboratório e casa de vegetação.bitstream/item/38181/1/DOC200467.pd

Método para mapeamento de áreas de preservação permanente através do uso de imagens de satélite: bacia do rio Salobra, MS.

O objetivo deste trabalho é demonstrar um método que possibilite o mapeamento de áreas de preservação permanente em encostas (a partir das classes de declividades encontradas no terreno) e às margens dos rios (ambiente fluvial) localizadas junto à bacia do Rio Salobra (MS), tendo como apoio o uso do Código Florestal (Lei 4.771 de 1965). A metodologia adotada baseou-se na elaboração de um banco de dados em um Sistema de Informação Georreferenciada

Inclusion of shrimp waste meal in diet of free-range chickens

Shrimp waste meal (SWM) is a by-product from the processing of shrimp for human consumption. The value of SMW in feeding poultry is not well documented. The objective of this study was to determine the energy value and optimal inclusion level of SWM in the diet of growing chickens. A total of 180 one-day-old broilers were randomly assigned to five treatments with 0, 50, 100, 150 and 200 g/kg of SWM included in their diet. There were six replicates of six birds for each treatment. Dry matter intake (DMI) was not affected by the level of SWM that was fed. Retained dry matter varied from 72.39% in the diet that did not contain SWM to 66.97% in the diet with 200 g/kg of SWM. Nitrogen retention (NR) ranged from 54.70% to 70.10%; N ingested was between 18.71% and 24.03%. Energy intake ranged from 73.57% to 69.33% for the control and the diet with 200 g/kg of SWM, respectively. NR improved with increasing SWM inclusion levels. The apparent metabolizable energy (AME) and corrected apparent energy metabolizable (AMEn) ranged from 2928 to 2527 kcal/kg and 2774 to 2329 kcal/kg, respectively, relative to the control and 200 g/kg SWM diets. The energy consumption, in kcal/kg, of SWM consumed was AME = 2332-6.971 x SWM and AMEn = 2113-8.128 x SWM. High levels of SWM reduce the dry matter metabolization coefficient and metabolizable energy values in broilers during the growing phase, so it is recommended that up to 100 g/kg should be included, which would provide an AMEn of 1300.2 kcal/kg for free-range chickens in dry matter
