Abstract: The objective of this work was to evaluate the qualitative parameters and nutritional potential of silage of arboreal cotton (Gossypium hirsutum) shoots. The experiment was carried out in a 4×2 factorial arrangement, for two silage forms (in natura or pre-dried), with four treatments, as follows: without additives (WA); with inoculant (WI); with 2% ground corn (GC); and with 2% ground corn with inoculant (GC+I). The fermentative quality and nutritional parameters of the silages were evaluated. Fermentative quality was better in the WI and GC+I silages. The dry matter content was higher in the pre-dried silage, while the crude protein contents of in natura silage were higher in the WA and WI treatments. The lowest values of neutral detergent fiber and acid-digested lignin were observed in the WI treatment, for pre-dried silage. Total digestible nutrients and total volume of gas were higher in the pre-dried silage, in the WI and GC treatments, respectively. In vitro dry matter digestibility was lower in WA silage, in both forms. Silage of arboreal cotton associated with inoculant or with inoculant with ground corn shows a better fermentation profile and improves the energy and nutritional values, both in natura and pre-dried forms; however, in natura silage is less laborious for rural producers.

Dry Matter Digestibility

The objective was to evaluate the productivity, chemical composition, ruminal degradability of dry matter and digestibility of BRS capiaçu grass (Pennisetum purpureum Schum.) managed at five regrowth ages. A completely randomized design with ten replications was used in the BRS capiaçu elephant grass subjected to five cutting intervals (30, 60, 90, 120 and 150 days) in the summer, making a total of 50 plots with a useful area of 4 x 2 m. There were daily increases in the dry matter production in the order of 382 kg ha-1, with 49,859 kg ha-1 being produced at 150 regrowth days. The dry matter content and organic matter linearly increased (P < 0.01) at different regrowth ages. The crude protein content, in vitro dry matter digestibility and in vitro digestibility of neutral detergent fiber linearly reduced (P < 0.01) 0.037%, 0.196% and 0.256% per day, respectively. Potential degradability of dry matter decreased from 68.9% at 30 days to 44.7% at 150 regrowth days (0.194 percentage units per day). The rate of degradation of fraction B 'c' was not modified (P = 0.94), averaging 1.46% hour-1. In the cultivation of BRS capiaçu elephant grass in the summer season, in the northern region of Minas Gerais, the age for harvesting between 90 and 120 days of regrowth is recommended.

Cutting Height

The goal of this study was to assess the dehydration curve and nutritional value of Tifton 85 bermudagrass at two cutting heights from ground level (4 and 8 cm) during 120 days of storage in a closed shed. The dehydration curve was determined using samples from the entire plant at eight different times. The experimental design consisted of randomized blocks with plots subdivided per times and five replicates. The second step consisted of assessing the nutritional value of the stored Tifton 85 bermudagrass in randomized blocks with plots subdivided per times and two treatments per plot: cutting height of four and eight centimeters from the ground, and five different times for the subplots, with five replicates. Dehydration of Tifton 85 bermudagrass at the two heights occurred in 48 hours, considered an ideal time for hay drying. The dry matter content responded quadratically to the time of storage of the two heights, only differing during baling and after 120 days of storage. Crude protein content had a quadratic behavior in the two cutting heights, with the smallest value after 30 days of storage (107.0 g kg-1) and the largest after 90 days (147.8 g kg-1) in the cutting height of eight centimeters. The ether extract exhibited a quadratic behavior in the two cutting heights, only differing after 90 days of storage. The neutral detergent fiber content had linear positive response according to the time of storage, with no difference between the cutting heights. For the neutral detergent fiber content in the two cutting heights, the quadratic regression model was the best fit to the data, differing between the heights after 30 and 60 days of storage. In vitro dry matter digestibility and in vitro cell wall digestibility values of the stored hay were lower than the values obtained at the time of cutting. Cutting performed at four centimeters from the ground was the most suitable for hay production due to higher dry matter production and nutritional value without difference between bailing treatments. Hay storage caused undesirable changes in the nutritional value, especially in fiber content and in vitro digestibility.

Abstract This study evaluated dry matter yield and nutritional characteristics of different oat genotypes (Avena spp.) for ensiling. Treatments consisted of genotypes of white oat IPR 126 (Avena sativa), black oat Cabocla IPR and Agrocoxilha (Avena strigosa), and BRS Madrugada and BRS Centauro (Avena vertis). Oats were harvested at the phenological stage of milk/dough grain. The design was a completely randomized block scheme, with five treatments and three replications per treatment. The IPR Cabocla genotype showed the highest dry matter content (before and after silo opening) and in vitro dry matter digestibility of fresh forage. No differences were observed for in vitro dry matter digestibility and dry matter losses among silages. The highest silage digestible dry matter yield (kg ha-1) was observed for the BRS Centauro genotype. Thus, despite the better nutritional quality presented by the IPR Cabocla genotype before ensiling, BRS Centauro genotype presented a higher yield of digestible dry matter per hectare.

The objective of this study was to conduct a meta-analysis of scientific publications from January 1994 to December 2014, to evaluate the chemical composition of corn plants, green forage, and silages of three different types of maize hybrids (simple, double, and triple) used in experimental conditions in Brazil. The sub-bases Corn Cultivation and Green Fodder were composed of 49 experiments, consisting of 481 treatments, and the sub-base Silage consisted of 24 studies composed of 163 treatments, involving 478 silos. In the Corn Cultivation sub-base, the variables of spacing, plant height, grain yield, organic matter content, and total carbohydrates of maize silage differed (P < 0.05) according to the hybrid type. The number of corn plants per hectare, number of spikes per plant, and the levels of neutral detergent fiber, acid detergent fiber, hemicellulose, and lignin did not differ (P > 0.05) according to the hybrid type. In the Green Forage sub-base (ensilage), the main difference (P < 0.05) was regarding the in vitro dry matter digestibility, whereby the triple hybrids (59.38%) had lower values than the simple (73.05%) and double (72.74%) hybrids. In the Silage sub-base, the variables of organic matter, total carbohydrates, cellulose, in vitro dry matter digestibility, and pH differed (P < 0.05) according to the hybrid type. While the variables dry matter, non-fibrous carbohydrates, neutral detergent fiber, acid detergent fiber, hemicellulose, lignin, total digestible nutrients, ethereal extract, crude protein, and ammonium nitrogen did not differ (P > 0.05) according to the hybrid type. The variability in the determination of parameters, such as dry matter yield, dry matter content, and non-fibrous carbohydrates of corn silage, and the non-determination of the starch content demonstrated that the chemical compositions of Brazilian corn silage have not yet been fully clarified. The types of maize hybrids (simple, double, and/or triple) mainly differ in terms of grain production. In many situations, the silage processes are not conducted in an ideal way, and the differences as a function of the maize plants (type of hybrid) are minimized due to losses during the ensiling process.

The objective of this study was to evaluate the agronomic characteristics, bromatological-chemical composition and digestibility of 11 corn cultivars (Zea mays) harvested at two cutting heights. Cultivars D 766, D 657, D 1000, P 3021, P 3041, C 805, C 333, AG 5011, FO 01, CO 9621 and BR 205 were evaluated when they were harvested 5 cm above ground (low) and 5 cm below the insertion of the first ear (high). The experiment was designed as random blocks, with three replicates, arranged in an 11 x 2 factorial scheme. Cultivars presented similar productions of forage dry matter and grains. Percentages of stalk, leaf, straw, cob and kernel fractions were different among cultivars, as well as dry matter content of the whole plant at harvest. Considering the whole plant, only the contents of gross energy, nitrogen in neutral detergent fiber, and in vitro neutral and acid detergent fiber digestibility did not differ among cultivars. Increase on the cutting height improved forage quality due to the reduction of stalk and leaf fractions and contents of cell wall constituents.

Eight sorghum (Sorghum bicolor L. Moench) genotypes were evaluated during four consecutive 60-day cuttings at two locations in Puerto Rico. Differences between genotypes and cuttings were significant for the eight traits studied (green forage yield, content and yield of dry matter and crude protein, in vitro dry matter digestibility, plant height and leaf area). The location x genotype interaction was significant for most traits except dry matter content and in vitro dry matter digestibility (IVDMD). At both locations the best dry forage producers over the 240-day period were ATx623 x Rio and ATx623 x TMTx430 with 34 and 30 t/ha, respectively, al Isabela; and 20 and 19 t/ha, respectively at Mayagüez. Average IVDMD and crude protein values of hybrids were 58 and 10.2%, respectively. Rio was lowest in dry forage yield but highest in IVDMD value: 62%. Leaf area had a high positive correlation with the three yield criteria. A rough estimate of net profit from growing forage sorghum in Puerto Rico for milk production is $1,211/ha.

This experiment was conducted to evaluate the effects of chemical and physical treatments on the chemical composition and in vitro dry matter (IVDMD) and organic matter (IVOMD) digestibility of corn stover. Seventy five bales of corn stover (25 ground, 25 chopped, and 25 whole) were treated with 4% ammonia (NH3) of the dry matter weight. A completely randomized design with factorial array 2x3 (0.0 and 4.0% NH3 and three particle sizes). Results indicated that dry matter content decreased as particle size increased. Protein content increased by 110, 116 and 91 units for the ground, chopped and whole corn stover treated with NH3 with respect to the control. Ether extract increased by 7.3% for corn stover treated with NH3. Similar trend was followed by the ash content which increased by 6.0% for corn stover treated with NH3. Ammonia treatment affected negatively the neutral detergent fiber values by 20.0, 7.0 and 7.7% for ground, chopped and whole corn stover, respectively. Similar results were found for acid detergent fiber with values of 7.17, 12.53 and 11.42% lower for ground, chopped and whole corn stover, respectively; than those found for the untreated material. IVDMD and IVOMD were increased with NH3 treatment.

Nutritional Characteristics

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.

Olive Pomace

In this study, corn silage with different ratios of by adding olive pomace olive industry by-product under laboratory conditions was aimed to determine the effects on nutrient contents, fermentation characteristics and in vitro digestibility. Olive pomace used in the research, was added in 0% (control), 20 and 40 levels in corn silage and ensiling period continued during 56 days. At the end of the ensiling period, differences seen in terms of dry matter content, organic matter, crude fat, acit detergent fiber, acid detergent lignin, in each level consisting of corn silage is added to olive pomace were found significant but the crude protein content of the olive pomace-added silages decreased. The highest crude fiber value was determined in the silages added with 40% olive pomace. Crude ash, lactic acid, acetic acid, pH and CO2 differences seen in terms of rates were not found significant. Propoionic acid wasn’t found in the groups to which olive pomace was added, while butyric acid and ammonia nitrogen weren’t observed in all silage groups in the study. At the same time, in vitro organic matter, dry matter and neutral detergent fiber digestibility of silages increased in each level consisting of corn silage is added to olive pomace. As a result, it was considered result that olive pomace the oil industry by product can be a silo feed quality. In particular, the corns by adding 40% of the olive pomace made silage were obtained satisfactory results in terms of both physical and chemical properties.

The aim of this study was to observe the properties of ten maize hybrids from Serbia including agronomic traits, lignocellulosic fibre composition and in vitro dry matter digestibility. Five yellow kernel dent hybrids and five analogue red kernel hybrids were used in this study to evaluate the agronomic traits, dry matter content of the whole plant, lignocellulosic fibre composition, ratios between different fibres, in vitro dry matter and NDF digestibility. Correlation coefficients between the investigated traits of the maize hybrids were assessed. Even though the results of our study showed variations regarding nutritional composition of the whole maize plant between the investigated maize hybrids, the hybrid and the differences in kernel colour (yellow or red) did not considerably affect the properties that influence quality of the maize hybrids for silage production. The highest IVDMD was determined in yellow kernel hybrid ZP 388, while the maximum NDFD was detected in the red kernel hybrid ZP 606red which also showed the lowest ADL/NDF and ADF/NDF ratios. The results indicate that all of the hybrids used in this study are good candidates for the production of high-quality silage for ruminant nutrition.
