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 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.

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 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.

ABSTRACT. Fermentation of rice straw incriased its nutritive value, digestibility and palatability. The aim of the present experiment was to study the effect of feeding rations composed of fermented rice straw supplement with urea and probiotic, and mixed with concentrate. Eighteen Etawah -grade bucks (age 1.5 years) were assigned into a completely randomized design to study nutrient intake and apparent degestibility of three dietary treatments. The rations as treatments were as follow: CFR=concentrate + chopped fermented rice straw:; Complete=concentrate + groud fermented rice straw; ELG = concentrate + elephan grass. Dry matter (DM) and crude protein (CP) intake of bucks were not different significantly among treatments. Apparent degestibility of DM was not different, however CP was significantly lower (p0.05) for the GFR treatments compared to the other two treatments. These results suggest that fermented rice straw can be uded to substituse the fresh elephant grass.

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 work was to evaluate the dry matter production of elephant grass (Pennisetum purpureum) genotypes, managed under intermittent stocking. A completely randomized design was used, with two genotypes and three replicates. The treatments consisted of factorial combinations (2x2x2) of genotypes ('BRS Kurumi' and the clone CNPGL 00‑1‑3), two light interception levels (LI) at the onset of grazing (90 and 95%), and two post‑grazing canopy heights (30 and 50 cm). A total of 24 Holstein x Zebu crossbred heifers were used. The stocking density varied in order to finish the grazing periods in two days. The interval between the defoliation, based on 95% LI, resulted in a higher leaf mass per grazing cycle. The post‑grazing height of 30 cm did not affect the number of grazing cycles but provided a greater herbage accumulation rate. The cultivar BRS Kurumi has higher pasture growth, lower rest period, and greater number of grazing cycles, which results in increased forage production in the growing season.

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.

ABSTRACT EFFECT OF THE ADDITION OF RICE BRAN AND CORN FLOUR ON THE PHYSICAL QUALITY OF ENSILAGE ELEPHANT GRASS (Pennisetum purpureumcv.Hawaii). The purpose of this research was to determine the effect of the addition of rice bran and corn flour on the physical quality of elephant grass (Pennisetum purpureum cv. Hawaii)silage.The present study used elephant grass (Pennisetum purpureum cv. Hawaii)in the ensilage process. Rice bran and corn flour were then added to the elephant grass in the ensilage processing. The present study used Completely Randomized Design with 7 treatments and 5 replications. The treatments were formulated as follow: R0 = elephant grass 100%; R1 = elephant grass + 8% rice bran; R2 = elephant grass + 12% rice bran; R3 = elephant grass + 8% corn flour; R4 = elephant grass + 12% corn flour; R5 = elephant grass + 4% rice bran + 4% corn flour; R6 = elephantgrass + 6% rice bran + 6% corn flour. The variables measured were physical quality of elephant grass silage, including:  texture, color, and aroma. The research results showed that the addition of rice bran and corn flour did not significantly affect (P>0,01) ensilage color and aroma, but significantly affect (P<0,01) the texture of the ensilage. It can be concluded that the addition of  8% rice bran gave the best result on theensilage textureof elephant grass (Pennisetum purpureum cv. Hawaii).

The objective of this study was to evaluate the effects of regrowth age (RA) and cutting time (CT) of elephant grass (Cenchrus purpureus cv. Cameroon) on the fermentation profile, microorganism population, and nutritive value of the silage in two simultaneous trials at different sites. A 2 × 2 factorial scheme with two CTs (08:00 and 14:00) and two RAs (8 and 16 weeks) at ensilage was used in a completely randomized design, with four replicates in each trial, totaling 16 experimental units per trial. Results showed that ammonia nitrogen to total nitrogen content (N-NH3/TN) ranged from 71.8 (14:00; 16 weeks) to 137.0 g kg -1 (14:00; 8 weeks). Elephant grass silage harvested at 14:00 at 8 weeks had the lowest pH (3.53) and highest lactic acid content (39.7 g kg-1 dry matter). The in vitro dry matter digestibility (IVDMD) was higher (P < 0.05) in the silage of plants harvested at 8 weeks than in the silage harvested at 16 weeks (59.9 vs. 46.8%, respectively). In trial 2, elephant grass silage harvested at 14:00 had lower pH and acetic acid content. The IVDMD was higher in elephant grass silage harvested at 14:00, with values of 65.3% and 56.2% at 8 and 16 weeks, respectively. We recommend elephant grass harvested at 8 weeks of regrowth and cut at 14:00 to produce silage with better nutritive value and fermentative profile.
