A maioria dos perfis de poço utilizados nas avaliações petrofísicas de reservatórios possuem uma resolução vertical na ordem de um metro. Isto cria um problema quando as espessuras típicas das camadas são inferiores a um metro, uma vez que não há correção das leituras. Os perfis de alta resolução vertical como da ferramenta de propagação eletromagnética (EPT, Schlumberger), o dipmeter (SHDT, Schlumberger) ou das ferramentas de varredura acústica ou elétrica possuem uma resolução vertical da ordem de centimetros, mas apresentam uma limitada aplicação para as avaliações petrofísicas. Nós apresentamos um método para a deconvolução de um perfil de baixa resolução vertical que utiliza informações de um perfil de alta resolução vertical para identificar uma nítida interface entre camadas que apresentam valores da propriedade petrofísica contrastante, mas localmente constante em ambos os lados. A partir desse intervalo de controle, nós determinamos a função resposta vertical da ferramenta sob as condições atuais do poço com base no teorema da convolução. Utilizamos várias interfaces de modo a obter valores mais representativos da resposta da ferramenta. O perfil de baixa resolução é então deconvoluido utilizando a transformada discreta de Fourier (FFT) sobre todo o intervalo de interesse. É importante destacar que a invasão do filtrado da lama e a presença do bolo de lama não produzem efeitos danosos sobre o método, que foi aplicado a perfis sintéticos e a dados de campo, onde a aplicação de filtros com um correto ajuste de profundidade, bem como a própria escolha do intervalo de controle, antes da deconvolução, são de extrema importância para o sucesso do método.

O trabalho foi realizado na Embrapa Amazônia Oriental, em Belém, Pará, (1º28´ S 48º27´ W de Greenwich), com o objetivo de avaliar a influência da adição da torta de dendê (Elaeis guineensis) como alternativa para suplementação alimentar de ruminantes, em períodos críticos de produção de forragem na Amazônia Oriental. Foram determinadas as características nutricionais da torta de dendê, durante um período de 21 dias, com 16 ovinos, em gaiolas metabólicas individuais, distribuídas em delineamento inteiramente casualizado, em quatro tratamentos e quatro repetições, onde os tratamentos (T1, T2, T3 e T4) continham quicuio-da-amazônia (Brachiaria humidicola) e níveis crescentes de 10%, 20%, 30% e 40% de inclusão de torta de dendê. Os consumos de matéria seca, em g/dia e % do peso vivo, foram de 666,6 e 2,5; 686.9 e 2,4; 649,4 e 2,4; e 540,9 e 2,0, de matéria orgânica 706,5; 710,8; 708,1 e 632,3 g/dia, e de proteína bruta 37,3; 42,9; 58,7 e 56,4 g/dia. O consumo de FDN, em g/dia, foi de 584,7; 583,5; 565,2; 527,0. Os coeficientes de digestibilidade da matéria seca foram de 50,3; 47,8; 52,2; e 55,2%, da matéria orgânica de 50,8; 49,6; 53,5; e 56,3% e de proteína bruta de 48,0; 38,7; 66,8; 69,4%, em T1, T2, T3 e T4, respectivamente. A torta de dendê possui potencial produtivo, com elevada disponibilidade de matéria seca e bom valor nutritivo, constituindo-se em alternativa para ser utilizada como suplemento alimentar para ruminantes, principalmente em períodos críticos de estiagem, em níveis em torno de 30%, e possibilita maior consumo e digestibilidade de matéria seca, matéria orgânica, proteína bruta, com suprimento adequado de energia.

We evaluated the effect of adding by-products from the processing of oil seeds in the diet of lambs on the carcass and meat traits. Twenty-four non-castrated weaned male Santa Inês lambs with approximately 70 days of age and initial average weight of 19.11 ± 2.12 kg were distributed into a completely randomized design. Treatments consisted of diets containing by-products with 70% of concentrate and 30% of tifton hay (Cynodon spp.) and were termed SM: control with soybean meal; SC: formulated with soybean cake; SUC: formulated with sunflower cake and PC: formulated with peanut cake. Diets had no effects on the carcass traits evaluated. There was no significant effect on the mean values of perirenal, omental and mesenteric fats (0.267, 0.552 and 0.470 kg, respectively) and there was no influence on the percentages of moisture, ether extract, crude protein or ash in the loin between experimental diets. Diets containing by-products from the processing of oil seeds did not change fatty acids found in lamb meat. The use of by-products from oil seeds provided similar carcass and meat traits, thus their use can be recommended as eventual protein and energy sources for feedlot lambs.

Inulin and oligofructose are fructans that can change important characteristics in original products when added in food. Two formulations of orange cakes (one containing 77.7g of inulin and another one 77.7g of oligofructose/inulin) and two formulations of breads (one containing 130g of inulin and another one 175g of oligofructose/inulin) were compared to the respective standard formulations (with no fructans) in relation to chemical composition, texture, volume, color and sensory acceptability with a nine-point hedonic scale. The cakes and breads with inulin and oligofructose/inulin showed greater amount of total dietary fiber in relation to standard products. The orange cake with inulin had lower cohesiveness and yellower dough when compared to the standard cake, but the addition of inulin and oligofructose/inulin reduced the acceptability for appearance, texture and flavor and the overall acceptability, although the acceptability for aroma was the same for the three products. The breads with inulin and oligofructose/inulin were harder and less cohesive than the standard bread, and bread with inulin showed minor volume in relation to the standard. The bread with inulin also presented crust with lower luminosity, dough with higher intensity of redness and yellowness and higher intensity of color in relation to standard, besides different hue. In relation to sensory acceptability, the bread with oligofructose/inulin had higher overall acceptability and flavor when compared to standard bread.

The experiment was conducted to evaluate the feeding behavior of lambs fed with diets containing 0, 12.5 and 25.0% of mulberry hay as a substitute for the concentrate. Twenty four Ile de France lambs, non castrated, with 25 kg of body weight and four months old, confined, in a completely randomized design, were used. The feeding daily time (242.01 minutes), rumination (435.48 minutes) and leisure (762.50 minutes), the numbers of cakes ruminated per day (658.36) and the time spent per cake (40.03 sec) were not affected (P>0.05) by different levels of hay in mulberry concentrate. The dry matter voluntary intake (1.258 kg/day) and neutral detergent fiber intake (0.302 kg/day), as well as the efficiency of dry matter intake and rumination (316.24 and 173.54 g/h, respectively) and efficiency of neutral detergent fiber intake and rumination (75.89 and 41.68 g/h, respectively) were similar in all treatments. The ruminating chew expressed in hour/day (11.29) and the number of chews expressed per cake (72.65) and per day (47.638.06), as well as the number and the feeding time (22.02 meals and 11.23 min/meal), rumination (25.95 ruminations and 17.29 min/rumination) and idle (41.81 idle and 18.30 min/idle time), were also not affected (P>0.05). The inclusion of mulberry hay did not change the rumination expressed in g of DM and NDF/cake (1.91 and 0.46, respectively) and min/kg of DM and NDF (361.51 and 1.505.78, respectively), as well as the total chew expressed in min/kg of DM and NDF (563.70 and 2.347.19, respectively). The use of mulberry hay partially replacing the concentrated, does not change the feeding behavior of feedlot lambs.

The aim of this work was evaluate introduction of byproducts of oleaginous in lambs feeding. Diets were composed for 30% of Tifton hay and 70% of concentrate based on corn grain, soybean meal, soybean cake, sunflower cake and peanut cake, limestone and mineral mixture, as dites: FS - control with soybean meal, TS - soybean cake as part of the concentrate, TG sunflower cake as part of the concentrate and TA - peanut cake as part of the concentrate. For performance evaluating 24 Santa Ines lambs with initial age and weight of 70 days and 19 +/- 2 kg, according to a completely randomized design. For digestive evaluate, weight Santa Ines sheep with initial age and weight of 70 days and 16 +/- 1.2 kg, adapted to the use of bag, for collect feces. Animals were distributed in a replicated 4 x 4 Latin Square and means were compared by Tukey's test with 5% significance level. By the performance trial, duration of confinement, weight gain, fed conversion and the dry matter intake were not affected (P>0,05), with averages of 54.29 days, 259 g/day, 4.29 kg of DM/kg and 1.32 kg/day, respectively. There were no difference P>0,05) for intake DM, OM, CP, CT and CE among diets, digestibility trial with averages of 76.23; 74.47; 76.44; 41.12; 73.00 and 93.00%, respectively. There were no differences for digestibility DM, OM, CP, ADF, CT and NCF. The partial substitution of the soybean meal for byproducts of oleaginous was a good proteic alternative in the feeding of lambs.
