Physical, chemical and sensory properties of gluten-free kibbeh formulated with millet flour (Pennisetum glaucum (L.) R. Br.)

Pearl millet flour was utilized in kibbeh formulations instead of whole-wheat flour. Physicochemical properties, oxidation stability and sensorial characteristics of control kibbeh made with whole-wheat flour (CT) were compared with kibbehs prepared with millet flour (roasted or wet) and stored for 90 days (–18 °C). Kibbeh prepared with millet flour presented good oxidation stability (TBARS concentration). Baked kibbehs (with roasted millet flour) presented good acceptability and kibbeh samples did not differ significantly (p > 0.05) from the whole-wheat flour sample, when global appearance, texture and flavor were evaluated. Millet flour could be a suitable ingredient for kibbeh formulations, maintaining their nutritional value and sensorial quality in addition to being a gluten-free product.

Diferentes Níveis de Grão de Milheto (Pennisetum glaucum (L.) R. Brown) na Alimentação de Suínos

Foi desenvolvido um experimento com a finalidade de determinar a viabilidade da inclusão do milheto (Pennisetum glaucum (L.) R. Brown) em rações de suínos em fases de crescimento e terminação, observando seu efeito sobre o consumo diário de ração, ganho diário de peso e conversão alimentar. Foi observado também o efeito da adição de milheto sobre as características de carcaça, sendo utilizados 60 leitões machos, híbridos de linhagem comercial, com peso médio inicial de 22,7 kg. Os tratamentos foram 0, 15, 30, 45 e 60% de inclusão de milheto nas rações de suínos. O delineamento utilizado foi o inteiramente casualizado, com cinco tratamentos e seis repetições, sendo utilizados dois animais por unidade experimental. Utilizou-se, ainda, os desdobramentos dos graus de liberdade de tratamentos, para a realização da regressão polinomial. Não houve efeito dos níveis de inclusão de milheto sobre o desempenho, nas fases de crescimento e terminação, nem sobre as características de carcaça. Concluiu-se que a adição de milheto em rações de suínos é viável. Considerando-se os preços dos ingredientes durante este experimento, a adição de 45% de milheto mostrou-se mais eficiente economicamente.

Composição química, digestibilidade dos nutrientes e da energia de diferentes milhetos (Pennisetum glaucum (L.) R. Brown) em suínos

Foram conduzidos dois ensaios de digestibilidade, objetivando-se estudar o valor nutricional de quatro diferentes milhetos (BN2, COMUM, IAPAR e IAPAR-REPASSE) processados em moinhos com três tipos de peneiras (diâmetros de furo de 3, 2 e 1 mm). Os coeficientes de digestibilidade (CD) da energia bruta (CDEB) e o coeficiente de metabolizabilidade (CM) da energia bruta (CMEB) relativos à peneira de 3 mm foram: 63,09 e 61,20% (COMUM); 71,57 e 69,66% (IAPAR) e 67,39 e 65,60% (BN2). Os CD e CM da energia do COMUM foram inferiores ao IAPAR e ambos foram semelhantes ao BN2. O IAPAR-REPASSE apresentou CDEB de 70,62% e CMEB de 68,49%, semelhante ao IAPAR. O IAPAR-1 mm apresentou maior CDEB e CMEB (84,61 e 81,41%) que o IAPAR-3 mm (70,59 e 68,71%) e o IAPAR-2 mm (77,73 e 75,46%). Os valores de energia digestível (ED) e energia metabolizável (EM) para o IAPAR (3 mm) foram de 3.030 kcal/kg e 3.001 kcal/kg, respectivamente. Verificou-se ED de 3.083 e 3.355 kcal/kg e em de 2.993 e 3.228 kcal/kg para o IAPAR (2 e 1 mm). O IAPAR-REPASSE apresentou valores de 2.849 kcal/kg (ED) e 2.763 kcal/kg (EM), enquanto o COMUM (3 e 2 mm), de 2.574 e 3.022 kcal/kg (ED) e 2.497 e 2.932 kcal/kg (EM), e o BN2 (3 e 2 mm), de 2.692 e 3.047 kcal/kg (ED) e 2.620 e 2.966 kcal/kg (EM). As diferentes variedades de milheto apresentaram variações em sua composição química que resultaram em diferenças no valor nutricional, sendo o milheto IAPAR o que apresentou melhor valor, seguido pelo BN2 e o COMUM.

Comportamento ingestivo de vacas leiteiras alimentadas com silagem de milheto ou milho

The objective of this study was to evaluate the ingestive behavior of dairy cows fed corn and millet silage with a 5 mm particle size without inoculant, millet silage with a 5 mm particle size with inoculant, millet silage with a 20 mm particle size without inoculant, millet silage with a 20 mm particle size with inoculant. Five cows Holstein x Gir, with approximately 100 days of lactation at the beginning of the experiment and a mean body weight of 550 kg, producing an average of 15 kg of milk per day were used. The animals were arranged in a randomized 5 x 5 Latin square. The total feeding time, rumination time, chewing time, number of alimentary bolus, rumination time for bolus and number of chews was determined. The variables that make up the feeding behavior were not affected when the cows were fed different millet silages compared with corn silage. Cows fed corn silage and millet silage of 5 mm particle size had a higher intake of dry matter and neutral detergent fiber. A particle size between 5 and 20 mm, the presence or absence of inoculum and the type of silage with DM at 28%, does not affect the total feeding time, ruminating and resting of cows with an average production of 15.2 kg per day. The presence of the inoculant does not affect the intake of dry matter and neutral detergent fiber. Cows fed diets containing corn silage or pearl millet silage with a 5 mm particle size fed more DM.

Efeito de diferentes herbicidas, doses e volume de calda na dessecação de milheto [Pennisetum glaucum (L. Leek)]

The objective of this work was to evaluate the efficacy of different herbicides applied in post-emergence in the desiccation of pearl millet with different doses and spray volumes. For the desiccation, doses at 0, 25, 50 and 100% of the herbicide glyphosate (1,440 g ha-1) were used in 3 formulations (Original Round up, Round up Transorb and Round up WG), paraquat + diuron (500 + 250 g ha-1) and glufosinateammonium (800 g ha-1). In all treatments, 2 spray volumes (200 and 400 l ha-1) were used, and there was 1 treatment (control) without the application of herbicides. The treatment effects were evaluated visually at 3, 7, 14, 21 and 28 days after application (DAA). At the end of the evaluations, the dry mass of the plants was determined. The field trial was carried out in randomized block design. At the end of the study, at 28 DAA, all treatments presented total control of plant pearl millet, regardless of the dose and spray volume, except the treatments with paraquat + diuron and glufosinate-ammonium at the lower dose (25%), in 2 spray volumes, which nevertheless showed good and very good control, these two herbicides presenting an effect of volume, in which the control was higher with the use of smaller volume.

Effects of charcoal-enriched goat manure on soil fertility parameters and growth of pearl millet (Pennisetum glaucum L.) in a sandy soil from northern Oman

The effect of charcoal feeding on manure quality and its subsequent application to enhance soil productivity has received little attention. The objectives of the present study therefore were to investigate the effects of (i) charcoal feeding on manure composition, and (ii) charcoal-enriched manure application on soil fertility parameters and growth of millet (Pennisetum glaucum L.). To this end, two experiments were conducted: First, a goat feeding trial where goats were fed increasing levels of activated charcoal (AC; 0, 3, 5, 7, and 9% of total ration); second, a greenhouse pot experiment using the manure from the feeding trial as an amendment for a sandy soil from northern Oman. We measured manure C, N, P, and K concentrations, soil fertility parameters and microbial biomass indices, as well as plant yield and nutrient concentrations. Manure C concentration increased significantly (P<0.001) from 45.2% (0% AC) to 60.2% (9% AC) with increasing dietary AC, whereas manure N, P, and K concentrations decreased (P<0.001) from 0% AC (N: 2.5%, P: 1.5%, K: 0.8%) to 9% AC (N: 1.7%, P: 0.8%, K: 0.4%). Soil organic carbon, pH, and microbial biomass N showed a response to AC-enriched manure. Yield of millet decreased slightly with AC enrichment, whereas K uptake was improved with increasing AC. We conclude that AC effects on manure quality and soil productivity depend on dosage of manure and AC, properties of AC, trial duration, and soil type.

Espécies vegetais para cobertura do solo: influência sobre plantas daninhas e a produtividade do algodoeiro em sistema plantio direto

Este trabalho objetivou avaliar a produção, a persistência e os efeitos de coberturas vegetais sobre as plantas daninhas e a produtividade do algodoeiro em sistema plantio direto. Os tratamentos consistiram das espécies de cobertura: milheto (Pennisetum glaucum (L.) R. Brown), Brachiaria ruziziensis Germain & Evrard, sorgo forrageiro (Sorghum bicolor L. Moench), capim-pé-de-galinha (Eleusine coracana L. Gaerth), Crotalaria juncea L., Crotalaria spectabilis Roth, aveia-preta (Avena strigosa Schreb.), nabo forrageiro (Raphanus sativus L.), P. glaucum + C. juncea, P. glaucum + C. spectabilis, B. ruziziensis + C. juncea, B. ruziziensis + C. spectabilis, S. bicolor + C. juncea, S. bicolor + C. spectabilis, E. coracana + C. juncea, E. coracana + C. spectabilis, A. strigosa + R. sativus, P. glaucum + R. sativus e pousio. As espécies foram semeadas no final do verão, após a colheita de soja, e o algodoeiro BRS 269-Buriti, nove meses após. O delineamento experimental foi em blocos ao acaso, com quatro repetições. As espécies B. ruziziensis, B. ruziziensis + C. juncea, B. ruziziensis + C. spectabilis e P. glaucum + R. sativus produziram mais de 6,8 t ha-1 de biomassa seca. A palhada produzida pela B. ruziziensis garantiu boa cobertura do solo durante o ciclo do algodoeiro. A biomassa seca de B. ruziziensis, B. ruziziensis + C. juncea e B. ruziziensis + C. spectabilis reduziu a infestação de plantas daninhas até a época de semeadura do algodão e durante os estádios iniciais de seu desenvolvimento. Palhas de R. sativus e A. strigosa, solteiras e consorciadas, interferiram negativamente na produtividade do algodoeiro.

Soybean growth and yield under cover crops

The use of cover crops in no-tillage systems can provide better conditions for the development of soybean plants with positive effects on grain yield and growth analysis techniques allow researchers to characterize and understand the behavior of soybean plants under different straw covers. Thus, the aim of this study was to characterize, using growth analysis, yield components and agronomic performance of soybean under common bean, Brachiaria brizantha and pearl millet straws. The experiment was performed on a soil under cerrado in the municipality of Santo Antônio de Goiás, GO. The experiment was arranged in a randomized complete block design with three treatments (cover crops) and five replications. Soybean grain yield was lower in the B. brizantha straw treatment (3,708 kg ha-1) than both in the pearl millet (4.772 kg ha-1) and common bean straw treatments (5,200 kg ha-1). The soybean growth analysis in B. brizantha, pearl millet and common bean allowed characterizing the variation in the production of dry matter of leaves, stems, pods and total and leaf area index that provided different grain yields. The cover crop directly affects the soybean grain yield.

Soil chemical properties affected by cover crops under no-tillage system

The use of cover crops in no-tillage systems (NTS) can significantly improve the soil's fertility. Thus, a study was performed to evaluate changes in chemical properties of soil caused by cover crops in a no-tillage system. The field experiment consisted of the following crop rotation: cover crops/rice/cover crops/rice. The experimental design was in randomized blocks with three replications. Treatments consisted of four cover crops (Brachiaria brizantha(Hochst. ex A. Rich.) Stapf. cv. Marandu, Brachiaria ruziziensis R. Germ. and C.M. Evrard, Panicum maximum Jacq. cv. Colonião, and Pennisetum glaucum(L.) R. Br. cv. BN-2) and fallow (control treatment). Soil samples were collected at the beginning of the summer crop in Oct 2007, Oct 2008 and Oct 2009 at 0-5 cm soil depth. The use of cover crops provided for a significant increase in the level of nutrients, soil organic matter, cation exchange capacity, and base saturation in the soil. Soil fertility improved from the first to second year with the growing of cover crops. The soil under cover crops P. glaucum, B. ruziziensis, and B. brizantha showed higher fertility than the area under fallow.
