The objective of this study was to evaluate maize in consortium with forage in a crop-livestock system for silage production, with subsequent formation of pasture. The experimental design comprised randomized blocks, with four replications, two types of corn cultivation, intercropped with two Brachiaria species (marandu grass and convert grass), and with and without intercropping with the pigeon pea (Cajanus cajan) BRS Mandarin. Dry matter productivity, the morphological composition of the corn, the botanical composition of the Brachiaria and pigeon peas, and the bromatological composition of the silage and Brachiaria were evaluated, as well as the losses caused by effluents. The consortia did not interfere with the productivity of corn for silage, and the silage from the consortium with pigeon peas exhibited a higher concentration of crude protein, demonstrating that the modality of the integrated agricultural production system of corn culture with Brachiaria and pigeon peas is an alternative to increase the protein content of the ensiled material and provide greater diversity of the remaining forage.

Abstract: The objective of this work was to evaluate the effects of re-ensiling and bacterial inoculation on the quality of corn silage. The experiment was carried out in a 2x2 factorial design with or without inoculant (association of Lactobacillus plantarum and Propionibacterium acidipropionici), and with re-ensiling after 36 hours of aerobic exposure or only ensiling of the whole plant of 'BRS 1055' corn. The fermentative quality, nutritional parameters, dry matter losses, aerobic stability, and microbiological counts of silages were evaluated. Re-ensiling caused an increase of pH and in acetic acid and propionic acid concentrations, as well as in the dry matter (DM), crude protein, neutral detergent fiber, and neutral detergent fiber crude protein contents. Conversely, there was a reduction in the nonfiber carbohydrates concentration and in in vitro dry matter digestibility for the re-ensiled material. All changes were explained by the higher-effluent production and DM loss of re-ensiled material that was subjected to two compactions. Microbiology was not altered by the treatments. The use of inoculant altered ash content, but it did not influence other parameters. In contrast, re-ensiling after 36 hours of aerobic exposure caused a reduction in the nutritive value of corn silage and accentuated the DM losses.

This study characterizes the changes in leaf mass, morphological composition and nutritional value of leaf blades of palisadegrass (Urochloa brizantha cv. Marandu) under continuous grazing in the first year of implementation of pasture and after second year of the eucalyptus planting in an Integrated Crop-Livestock System and Integrated Crop-Livestock-Forest, which were tested in the four seasons. The experimental design was in random blocks, with three treatments: Crop-Livestock System (ICL) and Integrated Crop-Livestock-Forest with two eucalyptus tree densities (ICLF-1L, 196 eucalyptus trees ha-1 and ICLF-3L, 448 eucalyptus trees ha-1) and four replicates. Sixty castrated Nellore cattle with initial weight of 235.43 ± 25.46 kg and mean age of 16 ± 2.81 months were used during the growing phase under continuous grazing. The agronomic variables were: total dry mass of forage, leaves, stem and dead material; leaf: stem and live: senescent material ratios; and accumulation rate. The leaf: stem and live: senescent material relation did not obtain any difference between the evaluated systems. Dry matter, crude protein, fiber fractions and digestibility of leaf blades were evaluated. Dry mass of the forage (6775 kg ha-1), stem (2175 kg ha-1), senescent material (3175 kg ha-1) and dry matter content (28.6%) were greater in the ICL, whereas crude protein (11.3%) was greater in the ICLFs. On the other hand, accumulation rate and dry mass of leaf blades did not change between systems. Thus, until the first year of grazing, tree systems have advantages, because the forage production (accumulation rate) and leaf mass are similar to those of plants in full sun, besides showing higher nutritional value.

Corn was inoculated withLactobacillus plantarumandPropionibacterium freudenreichiisubsp.shermaniieither independently or as a mixture at ensiling, in order to determine the effect of bacterial additives on corn silage quality. Grain corn was harvested at 32–37% of dry matter and ensiled in a 4 L laboratory silo. Forage was treated as follows: bacterial types: B0 (without bacteria-control), B1(L. plantarum), B2 (P. freudenreichiisubsp.shermanii), and B3 (combination ofL. plantarumandP. freudenreichiisubsp.shermanii). Each 2 kg of chopped forage was treated with 10 mL of bacterial culture and allowed to ferment for 27 days. The first experiment determined the most suitable wavelength for detection of bacteria (490 nm and 419 nm for B1 and B2, resp.) and the preferable inoculation size (1 × 105 cfu/g). The second experiment analysed the effect of B1 and B2 applied singly or as a mixture on the fermentation characteristics and quality of corn silage.L. plantarumalone increased crude protein (CP) and reduced pH rapidly. In a mixture withP. freudenreichii, the final pH was the lowest compared to other treatments. As a mixture, inclusion of bacteria resulted in silage with lower digestibility than control. Corn silage treated withL. plantarumorP. freudenreichiieither alone or mixed together produced desirable silage properties; however, this was not significantly better than untreated silage.

Cow's milk is a food of high nutritional value for human diet, however, there is a need to comply with the norms suggested by Normative Instruction 62, to meet quality parameters. The objective of this work was to evaluate the quality of corn silage and milk, to verify if they are in accordance with the current legislation IN 62 and to verify the influence of the level of technification of some producers of the region of Morrinhos Goiás. Of the region, and applied a questionnaire to identify the degree of technification, classified as Specialized (ES), Semi-Specialized (SE). At the same time silage samples were collected at different points in the silos to evaluate pH, dry matter (DM), ash and crude protein (CP). Somatic cell counts (CCS), bacterial counts (CBT), fat and protein were quantified to evaluate milk quality. It was verified that the silage samples were with high percentage of ash, which causes loss in their quality. There was no difference between levels of gross protein technology. The CCS of the SE system was 392.40 higher than in the ES, CBT obtained higher value in ES. All variables are within the limits required by IN 62.

Silage Production

A field study was conducted near Guelph, Ontario, to investigate the effects of shade stress on the yield of corn grown for silage versus grain. The effects of shading on the quality of whole-plant corn silage were also examined. Shade was provided by two layers of fiberglass screen, which reduced the amount of light by approximately 65%. The shade treatments were applied during either the vegetative, reproductive or grain-filling stages of development. Shading at any stage reduced whole-plant dry matter (WPDM) yield at the silage corn harvest stage and the level of this reduction was relatively independent of the stage at which the shade was applied. Grain DM yield at the grain harvest stage was also reduced by light stress, with the greatest reduction resulting from light stress during the reproductive stage. However, for silage production, high stover yield compensated for the reduction in grain yield, resulting in little reduction in whole-plant yield. Shading during either the reproductive or filling stage reduced WPDM content due to reduced grain content and higher stover moisture content.Key words: Corn, silage quality, whole-plant corn silage

The objective of this study was to evaluate the production and chemical composition of silages of grass Tanzania and corn, grown single or intercropping. The experiment was conducted at UTFPR Câmpus Dois Vizinhos in the period between October 2011 and July 2012, a 600 m² area. The treatments were: TMI - single corn, TMT - corn and grass Tanzania consortium at the time of sowing, TT - Tanzania grass single, TT32 - grass Tanzania silage to 32% dry matter (content similar to that of corn). The experimental design a randomized block design with four treatments and five replications. Agronomic evaluations were performed 120 days after planting, as follows: number of linear-1 plants metro, plant height and ear insertion and number of ears.plants-1. In the grass we evaluated canopy height, where it was held the botanical separation in green leaves, dried and stem. Silage started being held in 100 mm PVC pipe (mini-silos) kept sealed for 60 days. At the time of opening of the silo were determined the following parameters: DM, pH, total loss of DM (PDM), specifies mass (SM), dry matter recovery indices (IRDM), losses gas (LG), and size particle. Chemical analysis of the results of OM, MM, ADF were higher for TMI treatments, TT and TT, respectively. CP and LIG had superior results for the treatments containing grass. Corn intercropping with grass Tanzania silage provides more crude protein and lignin compared to exclusive corn silage without damaging the crop yield. Silage maiden Tanzania has higher levels of ADF and crude protein as well as increased production of dry matter than corn silage. The grass Tanzania should be harvested with 30% DM as presented better pH values, higher dry matter recovery rate, less loss of gas as well as increased production of dry matter that Tanzania harvested at the same age corn.

Aim. To optimize the methane digestion process while using different recipes of substrate components of ag- ricultural origin. Methods. The chemical composition of separate components of the substrate of agricultural by-products, industrial wastes, fats of the agrorefi nery and corn silage was studied. Dry (organic) mass, crude protein (fat) fi ber, loose ash, nitrogen-free exhaust were estimated in the components and the productivity of biogas was determined along with the methane content. These data were used as a basis for daily recipes of the substrate and the analysis of biogas production at the biogas station in Kostkowice. Results. The application of by-products of agricultural production solves the problem of their storage on boards and in open containers, which reduces investment costs, related to the installation of units for their storage. Conclusions. The return on investment for obtaining electric energy out of agricultural biogas depends considerably on the kind of the substrate used and on technological and market conditions.

Due to the seasonal cycle of forage, the use of silage to feed animals provides nutrients throughout the year. However, its quality can be improved with the inclusion of additives and other products. Glycerol is a rich source of energy and present a high efficiency of utilization by animals. The purpose of this work was to evaluate the effect of glycerol inclusion on the chemical and fermentation characteristics of corn and sunflower silages. Two silage sources (maize and sunflower) were used and four levels of glycerol inclusion (0, 15, 30 and 45%) based on dry matter were carried out. The experimental design was completely randomized in a 2 x 4 factorial arrangement with five replications. The pH values and chemical composition of corn and sunflower silages were determined. In both silages there was increment of dry matter, non-fiber carbohydrates and total digestible nutrients (TDN) added to a reduction of crude protein, neutral detergent fiber and acid detergent fiber due to the glycerol inclusion. The corn silage required 45% glycerol to achieve the TDN level of the sunflower silage. The glycerol addition contributed to the increase in the nutritional value, offsetting loss of quality in the ensiling process.

The aim of this research is to know the extraction method of caterpillar pupa without detrimental to chemical composition to know the amount of pupa production of German caterpillar with two extraction methods per 100 grams of pupa To know the content of dry matter, organic matter, crude protein, crude fat, crude fiber and amino acid lysin, methionine, and vitamin E pupa oil of German caterpillar. The study was conducted from February to April 2017, at the Lab. Central University Tribhuwana Tunggadewi. Oil extraction analysis was conducted in the chemistry laboratory of Tribhuwana Tunggadewi University and chemistry laboratory of Poltek Malang. German caterpillar research material, German caterpillar pupa, pupa caterpillar germany extracted by maceration and sokletasi. German caterpillar pupa is obtained from German caterpillar breeders in Amadanom, Dampit, Malang Regency. This research uses two different extraction methods, namely cold extraction method (maseration method) and using heat method (soxhlet method). The conclusions of both research methods are known that the quantity of German caterpillar yield using soxhlet extraction method is more than the maceration extraction method. However, for the quality of the two methods it is still necessary to do further analysis to know the exact comparison of the two methods.

The effects of spring-applied nitrogen (0, 56, 112 and 224 kg/ha) and phosphorus (0 and 27.4 kg/ha) on the dry matter (DM) yield and forage quality of successive harvests of meadow foxtail (Alopecurus pratensis L.) were investigated. Nitrogen increased DM yield, crude protein, Cu, K and Zn contents and decreased P, Ca, Mg and Mn contents. Application of P in combination with N increased K content in the first cut and arrested the decline of P content due to N application in all cuts. The levels of dry matter digestibility and Cu declined in successive cuts whereas Mn content increased. At low N rates, Ca and Mg contents increased as the season advanced.
