Objetivou-se avaliar o padrão fermentativo e a bromatologia da silagem de capim- elefante cultivar Napier com as folhas de Embaúba na proporção de 50:50 aditivada com torta de semente de cupuaçu, cana-de-açúcar e fubá de milho em diferentes níveis. O experimento foi realizado em delineamento inteiramente casualizado, com quatro repetições por tratamento. Foram testados os tratamentos (0%), (5%), (10%) e (15%) dos aditivos citados. O material foi ensilado em mini-silos de tubos de PVC por 45 dias para efetivação do processo fermentativo. Foram avaliados pH, matéria seca (MS), proteína bruta (PB), fibra em detergente neutro e ácido (FDN/FDA), hemicelulose (HEM) e nutrientes digestíveis totais (NDT). O pH da torta de semente de cupuaçu e do fubá de milho estão dentro da amplitude preconizada na literatura. Os aditivos proporcionaram maior percentual de MS e PB em todos os tratamentos, testando estes dentro dos limites considerados aceitáveis para um adequado processo fermentativo. FDN e FDA aumentaram linearmente à medida que aumentou a inclusão de torta de cupuaçu e fubá, porém permaneceram abaixo do limite considerado limitante ao consumo voluntário dos ruminantes e a digestibilidade. Os aditivos adicionados na forragem de capim-elefante com folhas de Embaúba melhoraram o valor nutritivo da silagem.Palavras-chave: composição bromatológica, Cecropia paphytachua, ensilagem, Pennisetum purpureum. ELEPHANT GRASS SILAGE AND EMBAÚBA WITH ADDED ALTERNATIVE PRODUCTS IN THE WESTERN AMAZON  ABSTRACT: This study aimed to evaluate the fermentative pattern and the bromatological of the Elephant grass silage cultivar Napier with the Embaúba leaf’s in the proportion of 50:50, added with of cupuassu cake seed, sugarcane and corn meal at different levels. The experiment was carried out in a completely randomized design, with four replications per treatment. The treatments 0%, 5%, 10%) and 15% of the cited additives were tested. The ensiled material was in mini-silos of PVC pipes for 45 days to affect the fermentation process. pH, dry matter (DM), crude protein (CP), neutral detergent fiber and acid (NDF/ FDA), hemicellulose (HEM) and total digestible nutrients (NDT) were evaluated. The pH of the cupuassu and maize meal are within the range recommended in the literature. The additives provided a higher percentage of DM and PB in all treatments, and these were within the limits considered acceptable for an adequate fermentation process. NDF and ADF increased linearly as the inclusion of cupuassu cake and corn meal increased, but remained below the limits considered limiting the voluntary consumption of ruminants and digestibility. The additives added in the elephant grass fodder with Embaúba leaves improved the nutritive value of the silage.Keywords: bromatological composition, Cecropia paphytachua, ensilage, Pennisetum purpureum.

The experiment was conducted to determine the effects of three additives (molasses, cracked corn and corn-soybean) and inclusion levels (0, 2.5, 5, 7.5 and 10 %) on nutritive value of elephant grass (Pennistum purpureum) silage. The experimental design was a 3×5 factorial in a completely randomized design with each treatment replicated three times. Samples were obtained from Pasture Museum. Elephant grass stands at late vegetative stage were randomly selected and harvested at 7 cm stubble height. Grass was chopped into 2-3 cm length. Five hundred gram of the sample was weighed in each case; additives were added separately at the designated inclusion levels and mixed thoroughly. Materials were then tightly packed into laboratory silos compressed and sealed tightly and left for a fermentation period of 21 days. The results indicated crude protein (CP) was significantly greater (10.92%) in silage treated with corn-soybean additive compared with other additives. Crude fiber (CF) was observed to be lower in molasses treated elephant grass silage (27.74 %). Acid detergent fiber (ADF) and neutral detergent fiber (NDF) were both lower in molasses treated silage (24.76 and 43.26 % respectively). The CP was observed to increase with increased inclusion level of the additive while CF decreased. Values for digestible dry matter (DDM), dry matter intake (DMI)as a percentage of body weight and relative feed value (RFV) were greater (P<0.05) in molasses treated silage compared to corn and corn-soybean. The DDM, DMI and RFV values were higher (P<0.05) at 7.5 and 10 % inclusion levels. Significant interactions were observed between additives and inclusion levels in most parameters measured. It was concluded that molasses additive could be used in elephant grass silage during ensiling at 7.5-10 % levels of inclusion.

The aim of this study was to evaluate the addition of macauba palm cake (Acrocomia aculeata) on the chemical composition, fermentation and aerobic stability of elephant grass silages (Pennisetum purpureum). The experiment was performed in a completely randomized design with four replicates. The treatments were composed of six levels of macauba palm cake (0, 6, 12, 18, 24, 30%) as additive to elephant grass silage. Dry matter and ethereal extract content of the silage increased linearly with the inclusion of the additive. Addition levels of 15.54% would provide 35% of dry mass, and the limit of 7.00% of ethereal extract in the silage could be obtained with 10.47%. The neutral detergent fiber content reduced linearly from 68.97 to 52.59%, but lignin increased linearly from 6.56 to 7.70%. There was a reduction of 0.17% in the ammoniacal nitrogen content for each 1% of cake. The minimum value of dry matter losses (1.33%) was estimated to the inclusion level of 23.70%. The aerobic stability increased with inclusions between 18 and 24% of cake. The use of levels between 10 and 15% of macauba palm cake are sufficient to optimize dry matter and ethereal extract contents of the silages and to provide a high aerobic stability with minimum losses.

Abstract: The objective of this work was to evaluate the nutritional value of silages from tall-sized and dwarf elephant grass (Pennisetum purpureum) genotypes, intercropped or not with butterfly pea (Clitoria ternatea). The experiment was performed in randomized complete blocks, in a 4x2 factorial arrangement (four genotypes × two cropping systems). The genotypes intercropped or not with butterfly pea were: IRI-381 and Elephant B, tall sized; and Taiwan A-146 2.37 and Mott, dwarf. Forage was harvested 60 days after regrowth. In the silage from Mott grass intercropped with butterfly pea, lower contents of lignin (78.1 g kg-1), neutral detergent fiber (636.0 g kg-1), and neutral detergent insoluble protein (13.15 g kg-1), besides a greater dry matter recovery (873.3 g kg-1), were observed. The silage from Taiwan A-146 2.37 intercropped with the legume showed a greater crude protein content (136.1 g kg-1). In both silages, the ammonia nitrogen contents were quite reduced (26.4 g kg-1). However, greater residual water-soluble carbohydrate contents were observed in the silages from the intercrop (1.85 mg g-1) and from the Mott grass monocrop (1.51 mg g-1). Moreover, there was a lower in vitro dry matter digestibility (676.7 g kg-1) for the silage from the intercrop. Dwarf genotypes increase the nutritional value of elephant grass silage, compared with the tall-sized ones. Intercropping with butterfly pea improves silage fermentation characteristics, despite reducing its digestibility. Therefore, the ensilage of dwarf Mott elephant grass intercropped with butterfly pea shows more promising results.

The Stability

The objective of this study was to evaluate the effect of adding palm kernel meal (BP) as an additive in elephant grass silage. The chemical qualitative and fermentation were analysed in a completely randomized design with six treatments, one with no BP (C) and six replications, where the averages of the results of days of closing and opening were analysed by regression analysis. We collected samples at the time of ensiling and after 190 days of storage for evaluation of dry matter, crude protein, carbohydrates (total, non-fibrous, water-soluble, cellulose and hemicellulose), ash, lignin and ether extract. In aerobic phase, we collected samples for pH, ammoniacal nitrogen, fungi and yeasts. The elephant grass of this experiment showed values of 13.9% DM and 8.25% CP while the BP has 77.2% DM and 16.9% CP. The inclusion of BP had inhibited the growth of fungi and yeasts. The increase in the content of BP decreased the concentration of NH3-N. Higher concentrations of BP in silage were more stable, and the stability breaks in 72 hours, while the stability of C was 19 hours. Concentrations above 15% BP had no significant variations in pH in the aerobic phase. The inclusion of palm kernel meal at concentrations 10% to 15% can be used in silage of elephant grass, inhibiting undesired fermentation and making them more stable. Concentrations above this value may affect the nutritive value of silage by high lignin content of the additive.

Inclusion Level

The aim of this study was to evaluate the fermentative losses and nutritional value of elephant grass silages with the increasing of inclusion levels of dehydrated banana peel. The experiment was conducted in a completely randomized design, with six treatments and four replications, being the silage exclusively from elephant grass, and five levels of inclusion of banana peel to the elephant grass silage, as the following - 5; 10; 15; 20 and 25%, being added based on natural matter. The addition of the banana peel in the silage reduced linearly (p < 0.05) the pH, the ammoniacal nitrogen and the losses of the fermentative process. In addition, the inclusion of banana peel increased linearly (p < 0.05) the dry matter and non-fibrous carbohydrates. On the other hand, the neutral detergent fiber and the acid detergent fiber were linearly reduced with the inclusion of the banana peel (p < 0.05), but there was no change in the dry matter digestibility in situ. The inclusion of dehydrated banana peel in elephant grass silage reduces the losses of the fermentation process with more consistent results at the 25% inclusion level, however, it reduces the silage nutritional value due to fibrous and protein quality.

The objective of the present study was to evaluate the chemical composition of elephant grass silages supplemented with different levels dried cashew bagasse (DCB). Our experiment used a randomized design replicated four times, each replicate consisting of the following five treatments: 100% elephant grass; 95% elephant grass + 5% DCB; 90% elephant grass + 10% DCB; 85% elephant grass + 15% DCB; and 80% elephant grass + 20% DCB. The elephant grass was cut manually to a residual height of 5 cm at 80 days of age, and cashew bagasse was obtained from the processing of cashew stalks used in fruit pulp manufacturing in Mossoró/RN. Plastic buckets were used as experimental silos, and 90 days after ensiling the experimental silos were opened and the contents analyzed. The addition of dried cashew bagasse to silage linearly increased the levels of dried matter and crude protein by 0.59% and 0.13%, respectively, for each 1% addition (P < 0.05). The neutral detergent fiber and acid detergent content of the silages was reduced by 0.22% and 0.09%, respectively, for each 1% addition of the bagasse. The total carbohydrate content was not influenced by the bagasse addition (P > 0.05), and averaged 82.29%. The levels of non-fiber carbohydrate showed linear growth (P < 0.05) as the dehydrated cashew bagasse was added, and pH and ammoniacal nitrogen levels were reduced. The addition of the dehydrated bagasse to elephant grass silage improves its chemical composition, and it can be effectively added up to the level of 20%.

ABSTRACT: The co-digestion of swine manure with vegetable waste is an alternative that can increase the production of biogas and methane generated by the isolated digestion of manure. However, recommendations that are based on the best ratio between manure and forage, as well as the age of harvest, are still scarce in the literature. This study was conducted to evaluate inclusions (0, 25, 50, 75 and 100%) of the total solids (TS) of Elephant grass (Pennisetum purpureum Schum) harvested at two ages medium age (MA) at 45 days of growth and advanced age (AA) at 90 days in co-digestion with swine manure, using an entirely randomized design in a 5x2 factorial scheme. Batch digesters were used and biogas production was monitored for 12 weeks. There was influence of forage age (P <0.05) on the degradation of solids and neutral detergent fiber, with higher values for the substrates containing MA forage. The highest CH4 yields were obtained by the substrates containing MA forage in the inclusion of 27.7 and 31.6%, being 253.7 and 222.2 L of CH4 per Kg of total or volatile solids. The age of the forages influenced the onset and persistence of biogas production, being advantageous only in the inclusion of 25% of MA forage. The AA forage inclusion is not recommended for co-digestion with swine manure.

Potential Use

The purpose of this study was to evaluate the potential use of fruticulture waste as an additive in elephant grass (Pennisetum purpureum) cultivar Napier silage at different densities, defining the effect of fermentative quality, microbiological characteristics and bromatological composition. The experimental design was completely randomized with four replications in a 4 x 3 factorial scheme, comprising a control, banana waste (BW), mango waste (MW), and passion fruit waste (PFW) at three densities (400, 500 and 600 kg green matter [GM] m-3). The effect of ensiling density was greatest in the exclusively elephant grass silage, where a compaction of 600 kg GM m-3 contributed to improvements in fermentation and microbiological processes. The addition of banana waste to the elephant grass silage promoted improvements only in bromatological composition, raising the dry matter (DM), crude protein (CP), and non-fiber carbohydrate (NFC) content and reducing fiber components (neutral detergent fiber [NDFap] and acid detergent fiber [ADFap] corrected for ash and protein), but the addition of banana waste did not favor the fermentative or microbiological processes. The addition of passion fruit and mango by-products promoted increased DM and favored the fermentative, microbiological, and bromatological silage processes, regardless of density.

The objective of this research was to evaluated the inclusion of buriti fruit peel as additive on the fermentation profile, losses, chemical composition and degradability of elephant grass silage. We used a completely randomized design with five levels of buriti fruit peel (0, 50, 100, 200 and 400 g kg-1). The silos were opened after 28 days of storage. In situ degradability monitoring was conducted using a split-plot design in which four animals represented the blocks and silage supplemented with five levels of buriti fruit peel represented the treatments. The use of the additive in elephant silage increased dry matter (DM) (P < 0.001), ether extract (EE) (P < 0.001), ash (P < 0.001), neutral detergent fiber (NDF) (P < 0.001) and acid detergent fiber (ADF) (P= 0.0000). The pH (P= 0.0000), N-NH3 (P = 0.024) and there was a decrease in gas losses (P < 0.001), effluent losses and dry matter recovery (P = 0.218) not were influenced by the addition of buriti fruit peel. The inclusion of buriti fruit peel linearly reduced the ruminal degradability DM of soluble fraction (a) (P < 0.001) and potentially degradable insoluble fraction (b) (P < 0.001). The DM content increase with the addition of the buriti fruit peel to the elephant grass silage promotes improvements in the fermentation process, reduces losses of nutrients and ruminal disappearance of dry matter and does not significantly change the chemical composition with the inclusion of 166.7 g kg-1 of the buriti fruit peel.

The objective of this study was to evaluate the nutritive value of elephant grass silages with increasing levels of dried mango by-product (DMB). Five addition levels were studied (0, 4, 8, 12 and 16%) using 20 rams, in a randomized complete design with five treatments (addition levels) and four replications. Dry matter (DM), organic matter (OM), crude protein (CP), neutral detergent fiber (NDF), acid detergent fiber (ADF), ether extract (EE), total carbohydrates (TC), non-fibrous carbohydrates (NFC) intake and digestibility were evaluated, as well as the total digestible nutrients (TDN) and the silage nitrogen balance (NB). Mango by-product addition did not influence the DM, CP and TC intakes, the TDN level or the OM, CT and NFC digestibilities. On the other hand, DMB addition reduced the NDF and the ADF intakes, as well as the DM, CP, NDF and ADF digestibilities, and the NB of the silages. There was also a increasing linear effect of DMB addition on the EE and NFC intakes, and on EE digestibility. The elephant grass silage with DMB by-product may not be used as a single feed to ruminants because it reduces the NDF and the ADF intakes and the DM, CP, NDF and ADF digestibilities, as well as the nitrogen balance.
