The objective was to assess the agronomic characteristics and nutritional value of silages from sorghum genotypes without bmr mutation and carrying the bmr mutation. A total of 14 genotypes were used, 7 of which were conventional (BRS 655, BRS 658, BRS 659, BRS 610, VOLUMAX, 156x947216 and 156x947030) and 7 carrying the bmr6 gene (2014F15641, 2014F15645, 2014F15649, 2014F15653, 2014F15661, 2014F15681 and 2014F15685). The experimental design consisted of randomized blocks – 4 blocks and 14 treatments, totaling 56 experimental plots. The means of the variables were subject to ANOVA through SISVAR; when significant was found, the treatments were compared using the Scott-Knott test at a 5% probability level. There was a difference (p < 0.05) for flowering days and height between genotypes. As for crude protein, mean levels ranged from 11.10 to 14.66% for 2014F15645 and BRS 610. Regardless of the mutation, there was no difference (p > 0.05) between the genotypes carrying the mutation and those not carrying the mutation for lignin and in situ dry matter digestibility. Genotypes BRS 655, BRS 658, BRS 659, BRS 610, VOLUMAX, 2014F15645, 2014F15649, 2014F15661, 2014F15681 and 2014F15685 are more suitable for silage production, as they present higher dry matter production. Regarding ISDMD, all genotypes can be used for silage production.

The objective of this study was to determine the agronomic characteristics, chemical composition and in situ degradability of different sorghum genotypes. The experiment was conducted at the National Maize and Sorghum Research Center – Sete Lagoas, MG. For agronomic and nutritional characteristics, a randomized block design was used, and for in situ degradability, a split-plot design was applied. Genotypes 13F2006, BRS655 and Volumax showed lower dry matter productivity compared to 12F02006 and 12F03033. Genotype BRS655 had the lowest levels of neutral detergent-insoluble fiber (NDF), acid detergent-insoluble fiber (ADF) and lignin. Furthermore, no difference was found for potential degradability (PD), indigestible fraction (IF), and effective degradability (ED) at 2; 5 and 8% hour-1 DM among the studied materials. Genotypes 12F03033 and 12F02006 combine higher productivity and nutritional quality.

This study aimed to evaluate the fermentation profile and nutritional value of millet grain silages rehydrated with whey and/or molasses. The experiment was conducted in a completely randomized design with four treatments and six replications, with a control treatment (water rehydration), whey rehydration, water rehydration plus molasses (2.5%), and whey plus molasses (2.5%). Lower values of dry matter content (DM = 66.37; 1.55%) were found for the control silage, but within the recommended range. The contents of crude protein, neutral detergent fiber, acid detergent fiber, lignin and hemicellulose were not influenced by the use of additives. There was no difference (p>0.05) for aerobic stability and ammonia-N (6.04%) between treatments. For pH, lower values were observed for silages with molasses. There was a higher concentration (p

A silagem surgiu como uma alternativa de conservação de alimento para ser utilizada posteriormente, sem que o alimento perca sua qualidade nutricional. Muitas propriedades que utilizam esse recurso pertencem a regiões com chuvas concentradas em determinadas épocas do ano e o resto do ano ficam sem chuvas, onde nessas situações a silagem de sorgo é de extrema importância para manter os animais. Pequenos produtores que possuem propriedades pequenas não conseguem produzir seu próprio alimento, tendo então a alternativa de comprá-lo fora e reensilar na propriedade. O objetivo principal do uso de inoculantes microbianos é impedir que haja crescimento de microrganismos aeróbios, inibindo assim a degradação das proteínas, uso dos açucares remanescentes, e perdas de matéria seca. Com base no exposto, objetivou-se por meio deste trabalho avaliar a qualidade da “reensilagem” de sorgo com e sem aditivos em diferentes tempos de abertura.

A produção de silagem é uma forma de armazenar alimento para os animais, podendo ser utilizado para a mantença desses no período das secas, onde a oferta de alimento é pouco, além de ser de baixa qualidade. A falta de planejamento ou devido ao ambiente muitas vezes leva o produtor a comprar o alimento para seu rebanho fora da sua propriedade. A compra de silagem em grande quantidade em alguns casos requer a reensilagem para o fornecimento posterior para diminuir os gastos com o transporte. Com isso, objetivou-se com esse trabalho avaliar a qualidade e o valor nutricional da “reensilagem” de sorgo com e sem aditivos em diferentes tempos de abertura.

Para o desenvolvimento da pecuária brasileira é necessário que se melhore os índices zootécnicos que são considerados baixos, sendo necessária a aplicação de tecnologias de produção de volumoso de qualidade. Através da alta produtividade e resistência ao clima mais seco e a solos menos férteis, o sorgo se destaca como uma das espécies forrageiras mais usadas em climas mais secos para produção de volumoso. Com a grande demanda de materiais de melhor qualidade, surgiu a demanda de novos genótipos de sorgo, com isso Embrapa milho e Sorgo têm visado a introdução de genótipos com potencial de rendimento e tolerância a condições de estresses para a planta sem afetar a produção. Dessa forma, objetivou-se com esse trabalho avaliar a produção de matéria verde e matéria seca de diferentes genótipos de sorgo.

A produção de sorgo é quase que inteiramente voltada para alimentação animal, principalmente em forma de silagem, sendo ela muito importante para aumentarmos a produtividade dos nossos rebanhos bovinos. O valor nutricional do sorgo está ligado ao seu teor e lignina, que aumenta com o decorrer da idade da planta. Com os avanços na seleção genética dos genótipos de sorgo, têm-se obtidos sorgos com pigmentos marrons na nervura central, chamados de Brown midrid, que possuem um menor teor de lignina. Objetivou-se, com esse trabalho, avaliar as características agronômicas e matéria seca potencialmente digestível de genótipos de sorgo portadores ou não de nervura marrom bmr para a produção de silagem.

Dentre as espécies forrageiras, o sorgo se destaca devido à sua alta produtividade e resistência hídrica, podendo até mesmo fornecer uma rebrota, o que aumenta seu potencial para a produção de alimentos. Com isso, surgiu também genótipos de sorgo que possuem além da elevada produção, uma boa qualidade nutricional que é muito importante para a nutrição animal. Objetivou-se, com este trabalho, avaliar as características nutricionais de extrato etéreo e nutrientes digestíveis totais de diferentes genótipos de sorgo para potencial de produção de silagem.

O sorgo se destacou em região com maior deficit hídrico devido à sua resisitência. A cultura do sorgo se destaca pela rusticidade, elevada produção de biomassa e pela grande tolerância ao deficit hídrico. Essas características, associadas à sua grande eficiência energética, permitem o cultivo do sorgo em zonas áridas e semiáridas, com produção em diferentes épocas e regiões. O cultivo da cultura pode ser feito em diferentes densidades de plantas de acordo com o tipo utilizado e a variação climática da região. Essas características aliadas a outros fatores como o espaçamento, época de semeadura, profundidade, genética, adubação e nutrição, podem influenciar direta ou indiretamente a produtividade da cultura. Dessa forma, objetivou-se, com esse experimento avaliar a florescênica e altura de diferentes genótipos de sorgo.

A grande demanda por materiais de melhor qualidade favorece o surgimento de inúmeros genótipos, os quais têm influência marcante sobre o valor nutritivo da planta. Diante disto, estudos de comparação entre híbridos ou cultivares se tornam importantes para contribuir na escolha de materiais que apresentam a melhor relação de produção. A digestibilidade das forrageiras é um importante parâmetro que determina qual é o aproveitamento dos nutrientes. Objetivou-se, com esse trabalho, foi avaliar a digestibilidade da matéria seca e a produção de matéria seca digestível de diferentes genótipos de sorgo.

The objective was to evaluate the minimum size of experimental plots for the common bean (Phaseolus vulgaris L.) using the modified maximum curvature method. The experiment consisted of a uniformity trial with the cultivar BRSFC-402 sown at a spacing of 0.5 m between plant rows and 10 plants per meter within the row. 20 central rows measuring 20 m in length were considered for measurements, totaling 4,000 plants on an area of 200 m2. Final bean stand (FS), mean number of pods per plant (NPP), mean number of grain per pod (NGP), mean 100-grain weight (M100), and grain yield (kg ha-1) were evaluated. At evaluations, each row with 10 plants was considered a basic unit (0.5 m2), amounting to 400 basic units whose dimensions were combined into 14 plot shapes. The methods of relative information and modified maximum curvature were used to obtain the best shape and the most appropriate plot size, respectively, for experimental evaluation with common bean. Using these methods, and considering that the optimum plot should enable an efficient evaluation of all evaluated characteristics, the appropriate plot size was five UB (25 plants) in the format with five rows x one UB per row. Highlights • Support for experimental evaluation of common beans under edaphoclimatic conditions in the northern region of Minas Gerais • Experimental plots with five basic units ensure maximum precision for joint evaluation of the main phenotypic descriptors of common beans. • The characteristics mass of 100 grains and productivity were associated with the smallest and the largest plot sizes, respectively.

The objective of this study was to evaluate the chemical composition, pH and rumen degradability of banana tree pseudostems pre-dried and ammoniated with different doses of urea (0, 0.5, 1.0, 1.5 and 2.0% in natural matter). The experiment consisted of five treatments (doses of urea) with six replications, following a completely randomized design. There was a linear increase in the pH (P < 0.01) of the banana tree pseudostems pre dried with the inclusion of urea. There was no difference (P > 0.05) in dry matter, ash, neutral detergent fiber, acid detergent fiber, lignin, non-fibrous carbohydrates and total digestible nutrients; the averages were 31.58, 18.82, 46.43, 9.30, 11.87 and 42.52%, respectively. The inclusion of 2% urea increased the crude protein content (P < 0.01) by 42.75%, the soluble fraction "a" by 31.82%, and the potential and effective degradability of dry matter by 15.49% compared to that of the control group (without urea). The potentially degradable fraction, time of colonization and ruminal repletion of the neutral detergent fiber of the pre-dried banana tree pseudostems were not altered with the inclusion of urea (P > 0.05). The ammonization of the pre-dried banana tree pseudostems with 2% of urea improved the chemical composition and rumen degradability of the dry matter.

The objective was to evaluate the effect of inclusion of acetic acid during the ensiling of sugarcane (Saccharum officinarum) on fermentation quality and nutritional value. The treatments consisted of sugarcane silages, variety (IAC 86-2480) additives with four inclusion levels of glacial acetic acid (1.5, 3.0, 4.5 and 6.0 % in natural matter) plus the control. A completely randomized design was used, being 5 treatments and 6 replicates. The glacial acetic acid showed a pH 2.9 (0,1M). There was a reduction of 0.07 units in the pH of the sugarcane silage for each 1% inclusion of acetic acid (P < 0.01). The N-NH3 concentration was not modified in the ensiled mass of the treatments, with a mean of 0.45% in dry matter (P =0.91). The averages of effluent losses were adjusted to the quadratic regression model with the application of acetic acid (P < 0.01). There was a reduction in the yeast population in the order of 0.44 log UFC/g of silage (P < 0.01). The addition of acetic acid in sugarcane silage reduces fermentative losses, the yeast population and improves the nutritional value in doses from 1.5% of natural matter.

Objetivou-se avaliar a produtividade, composição químico-bromatológica, degradabilidade ruminal da matéria seca e digestibilidade do Capim-Elefante-BRS capiaçu (Pennisetum purpureum Schum.) manejado em cinco idades de rebrota. Foi utilizado o delineamento inteiramente casualizado com dez repetições, na cultivar BRS capiaçu de capim-elefante submetida a cinco intervalos de corte (30, 60, 90, 120 e 150 dias) no verão, perfazendo um total de 50 parcelas com área útil de 4 x 2 m. Foram verificados incrementos diários na produção de matéria seca na ordem de 382 kg ha-1, sendo 49.859 kg ha-1 a produção aos 150 dias de rebrota. O teor de matéria seca e matéria orgânica aumentaram (P < 0,01) linearmente nas diferentes idades de rebrota. O teor de proteína bruta, digestibilidade in vitro da matéria seca e digestibilidade in vitro da fibra em detergente neutro reduziram (P < 0,01) linearmente de 0.037%, 0.196% e 0.256% por dia, respectivamente. A degradabilidade potencial da matéria seca reduziu de 68.9% aos 30 dias para 44.7% com 150 dias de rebrota (0.194 unidades percentuais por dia). A taxa de degradação da fração B ‘c’ não foi modificada (P=0.94), média de 1.46% hora-1. No cultivo do Capim-Elefante BRS capiaçu na estação verão, na região norte de Minas Gerais, recomenda-se a idade para colheita entre 90 e 120 dias de rebrota.

This study evaluated the effect of increasing levels of leucaena forage in sorghum: forage. In addition to pure sorghum, it was evaluated different levels of inclusion of leucaena (15, 30 and 50%) at the time of ensiling. Forage was ensiled in PVC tubes (100 mm diameter, 500 mm length) under the density of 500 – 600 kg m-3, a total of 20 silos were prepared, which were opened 35 days after ensiling. There was no effect (p > 0.05) of leucaena inclusion levels for pH, water activity (Aw) and total ammonia nitrogen (total NH3-N). There was an increasing linear effect (p < 0.05) for the content of dry matter (DM), crude protein (CP) and lignin that increased from 33.47 to 34.75%, 7.82 to 16.05% and from 7.29 to 9.93%, at the levels from 0 to 50% inclusion of leucaena, respectively. There was a decreasing linear effect (p < 0.05) for neutral detergent fiber corrected for ash and protein (NDFcp) and hemicellulose, which reduced from 56.65 to 48.37% and from 24.07 to 17.67% at the levels of 0 and 50% inclusion, respectively. For the ash content, there was a quadratic effect (p < 0.05), with a maximum at 8.3% with 8.9% inclusion of leucaena. The inclusion of up to 50% leucaena into sorghum silage is recommended, because, in addition to maintaining the fermentation quality, it also improved nutritional quality of sorghum silage.

The objective of this study was to select sorghum genotypes for silage production. The study was carried out at Embrapa Maize & Sorghum’s experimental field. Planting was performed in randomized blocks, with three replicates and the Scott-Knott test at a 5% probability level. The material was ensilaged in laboratory silos opened after 56 days for analysis concerning fermentation and bromatological composition. Only crude protein showed no significant difference (p > 0.05), with an overall mean of 8.88%. The other variables presented significant differences (p < 0.05): pH (3.34 to 3.94); Aw (0.93 to 0.98); N-NH 3/TN (1.61 to 6.56%); green matter yield (12.05 to 34.14 t ha-1); dry matter yield (6.19 to 11.42 t ha-1); dry matter (26.89 to 49.95%); ashes (4.08 to 6.88%); neutral detergent fiber corrected for ash and protein (47.67 to 65.79%); acid detergent fiber (16.62 to 35.89%); hemicellulose:cellulose (1.07 to 2.71%); lignin (2.03 to 6.52%), digestible dry matter yield (3.70 to 7.41 t ha-1) and dry matter digestibility (56.36 to 72.67%). Based on digestible dry matter yield, the genotypes: male 201191 and hybrids 2012F47484, 2012F47515 and 2012F47525 stood out in relation to the others for showing good yielding, adequate nutritional value, with low dry matter and NDF levels coupled with high digestibility values and good fermentation patterns of the silages.

The objective of this study was to assess agronomic characteristics and nutritional values of silages of millet genotypes. Planting was done in randomized blocks, with five replicates per genotype. Green matter yield for genotypes ADR 500 and CMS 01 was higher and similar to each other, with 40.16 and 41.36 t ha (p > 0.05). There was no significant difference for dry matter yield, with the mean being 9.93 t ha (p > 0.05). The silages were similar (p > 0.05) as to pH, Aw and N-NH3/TN, presenting values of 3.92, 0.97 and 7.64%, respectively. There were no significant differences (p > 0.05) concerning the bromatological composition of the silages of the different genotypes, with a mean of 30.74% of dry matter, 10.21% for crude protein and 58.69% for neutral detergent fiber (p > 0.05). The dry matter digestibility mean stood at 59.90%. Based on the nutritional values and digestibility of the millet silages, the five genotypes are suitable for silage production, with potential for the North of Minas Gerais.

This study evaluated the nutritional characteristics of hay of nineteen hybrids between sorghum and Sudan grass. The experimental design was a randomized block with nineteen treatments and three replications. The chemical characteristics of the respective hays were analyzed 52 days after sowing and 45 and 49 regrowth days. Data were analyzed by analysis of variance, and when the F test was significant, the treatment means were compared by the Scott and Knott test at 5%. Genotypes 1013026 and 1014020 showed similar dry matter content. As for ether extract content, the highest values ranged from 2.20 to 2.66%. Higher values of minerals were observed in hybrids 1013026 and 1011005. In relation to crude protein, higher content values were reported for hybrids 1013021 and 1013020 (14.59 and 15.47% CP). When evaluating the neutral detergent fiber content, lower values varied between 56.05 and 57.07% for hybrids 1013016 and 1011009. Considering the content of acid detergent fiber, values ranged from 32.70 to 35.78%. Values of dry matter digestibility were higher than 50%. All hybrids provide quality hay, however the hybrid 1014019 showed the best nutritional value.

This study aimed to evaluate the nutritional characteristics and quality of silages of five sorghum genotypes, namely: Volumax, AG2005E, Qualimax, BRS610 and AG2501. The study was conducted at the Experimental Farm Unimontes, in the municipality of Janaúba, state of Minas Gerais. The treatments were distributed in a randomized block design with four replicates. Data were tested by analysis of variance andmeans were compared by Scott-Knott test at a significance level of 5%. The pH values ranged from 3.93 and 4.10. Genotypes differed in all studied nutritional characteristics (p < 0.05). For the acid detergent fiber, differences were detected between the genotypes, AG2501 (35.66%), Volumax (34.89%), AG2005E (34.53%), Qualimax (32.39%) and BRS610 (33.60%). The high participation of lignin was verifiedin all genotypes except for Volumax (4.14%). All silages were within the recommended range 50-65% for in vitro dry matter digestibility and classified as having good quality, however only the AG2005E genotype met nitrogen requirements for microbial fermentation, with 7.06% crude protein.

This study aimed to evaluate the agronomic performance of 24 sorghum genotypes in four Brazilian regions and the chemical characteristics of genotypes grown in Sete Lagoas, state of Minas Gerais. Genotypes BRS655 and 12F37005 had higher average production of green matter (> 44 ton ha-1) and dry matter (> 17 ton ha-1), respectively. Genotypes 12F38019, 12F40019, 12F37005, 12F37043 and Volumax took more days to flower in three of the four municipalities (75-90 days). Genotypes 12F38006, 12F40006 and 12F37016 were taller (> 2 m). Values of dry matter, crude protein and neutral detergent fiber ranged from 37.15 to 50.13; 5.51 to 10.28 and 43.57 to 65.69%, respectively. The genotypes were not different regarding acid detergent fiber content, with mean value of 34.83%. Genotypes 12F38019, 12F37016, 12F39005, 12F39019, 12F37007, 12F37014, 12F39014 and BRS 655 showed the best values of dry matter digestibility (64.31 to 74.20%) and crude protein content (8.33 to 10.28%). Among them, 12F139014 exhibited the lowest lignin content (3.32%), suggesting less effect of this fraction on digestibility. Genotype 12F39014 is the most suitable for cultivation, as it presented the best nutritional value and good dry matter production in the four municipalities.

The objective was to select sorghum genotypes for silage production using its chemical characteristics. The experiment was carried out in the facilities of Embrapa Maize and Sorghum in Sete Lagoas, state of Minas Gerais, to evaluate the agronomic characteristics, and nutritional quality of silage of twelve sorghum genotypes. We used a randomized block design with three replications. In relation to the production of green matter, the genotypes SF15 Volumax and BR610 stood out (52.07; 48.00 and 41.87 ton ha-1). Regarding pH, genotypes 1015339, 1015347, 1016007, SF15, BRS655, Volumax and BR610 averaged 3.68. All genotypes were similar considering the nutritional value, ammonia nitrogen and water activity. The genotypes SF15, Volumax and BRS610 showed the highest productivity per area, representing the best options for silage production.

The objective was to select from among 24 sorghum genotypes the superior ones for silage production. The study was conducted in the experimental field of Embrapa Maize & Sorghum, in the municipality of Sete Lagoas, Minas Gerais State. It used 24 forage sorghum genotypes, 21 being hybrids from the crossing of grain sorghum females and forage males (12F38019, 12F38006, 12F40006, 12F40005, 12F40019, 12F37016, 12F37005, 12F37043, 12F39006, 12F39005, 12F39019, 12F38005, 12F38007, 12F37007, 12F39007, 12F40007, 12F38014, 12F37014, 12F39014, 12F40014 e 12F38009) and three witnesses: BRS 610, BRS 655 and Volumax. It estimated productivity per area, in vitro dry matter digestibility, and assessed the bromatological and fermentation characteristics of sorghum silage. In vitro dry matter digestibility, unavailable protein in neutral detergent, neutral detergent fiber corrected for ashes and protein, acid detergent fiber, hemicellulose and lignin differed as to the genotypes tested. The pH and the ammoniacal nitrogen of the silage also showed differences between genotypes. Most of the genotypes tested are favorable for silage production, except the hybrid with higher lignin content 12F370014, and the hybrids 12F37007 and 12F370014, which showed the highest NDFap values.

This study aimed to evaluate in situ degradability and degradation kinetics of DM, NDF and ADF of silage, with or without tannin in the grains. Two isogenic lines of grain sorghum (CMS-XS 114 with tannin and CMS-XS 165 without tannin) and two sorghum hybrids (BR-700 dual purpose with tannin and BR-601 forage without tannin) were ensiled; dried and ground silage samples were placed in nylon bags and introduced through the fistulas. After incubation for 6, 12, 24, 48, 72 and 96 hours, bags were taken for subsequent analysis of fibrous fractions. The experimental design was completely randomized with 4 replicates and 4 treatments and means compared by Tukey’s test at 5% probability. As for the DM degradation rate, silage of CMSXS165without tannin was superior. Silages of genotypes BR700 and CMSXS 114 with tannin showed the highest values of indigestible ADF (59.54 and 43.09%). Regarding the NDF, the potential degradation of silage of CMSXS165 line without tannin was superior. Tannin can reduce ruminal degradability of the dry matter and fibrous fractions.

The objective was to assess agronomic characteristics of sorghum genotypes and nutritional values of produced silage. A total of 15 sorghum genotypes were used. Planting was carried out through a randomized-block design with three replications per genotype, totaling forty-five (45) plots. Agronomic and nutritional characteristics, besides the quality of the silage, were assessed. There were differences between genotypes for all characteristics analyzed, with the exception of levels of acid detergent unavailable nitrogen (ADUN), acid detergent unavailable protein (ADUP) and water activity (aw). The assessment of the parameters, except for genotypes 1016013, 1016025, 1016037, 1016039, Volumax and BRS 610, which presented protein level below 7%, showed that the other genotypes can be used for silage production, since they have a good profile of fermentation and in vitro dry matter digestibility; however, genotype SF15 is the most favorable one for silage production due to its little participation in the neutral detergent fiber fraction.
