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.

The spring forage emptiness is an obstacle to the development of Brazilian livestock, including in the Bioma Pampa region. Feed strategies for this period contributed to the development of livestock and to the conservation of the biome. The objective of this work was to know the nutritional potential of forages during spring forage for use as strategies in the forage planning. The experiment had a completely randomized design, with ten forages and four replicates. The chemical composition, in vitro dry matter digestibility (IVDMD) and the total digestible nutrient content (NTD) of elephant grass, brachiaria cultivars Convert and Marandu, Tifton 68; diploid and tetraploid ryegrass; red, white and arrowleaf clover; and bird’s-foot trefoil. The grasses had a higher proportion of fibrous constituents, and lower levels of NDT and DMD, thus, lower nutritional value. Negative correlation between mineral matter and fibrous constituents with CP, TDN and IVDMD, was observed. Forages studied can be used as pasture alternatives for ruminants in the spring forage emptiness of the Pampa, Brazil, however, the strategy of using them should be a pasture planning.

Water Soluble Carbohydrate

Preservation of forage with silage method has been widely practiced by farmers, one of the factors that influence the success of making silage is the addition of additives, such as molasses. However, molasses is not available in all regions. For that we need a material that can be an alternative substitute for silage, namely granulated sugar, besides having nutritional value that is almost the same as molasses, sugar also contains water soluble carbohydrate (WSC) which is easily utilized by lactic acid bacteria as an energy source during the ensilage process. This study aims to determine the effect of molasses and sugar levels on pH values and dry matter of elephant grass silage. The study used a completely randomized design (CRD) with 5 treatments and 3 replications, namely P1: control, P2: Molases 4%, P3: Sugar 4%, P4: Molases 6% and P5: 6% sugar. So that the total sample unit is 15 units and one unit of fresh material samples. Samples were analyzed in the laboratory to determine the pH value and dry matter of silage. The results showed that the administration of sugar additives at the level of 4% in silage had the same quality as silage which was given molasses at the level of 4%. However, at the level of 6% silage which is given molasses it has better quality than silage which is given sugar. This shows that granulated sugar can be used as an alternative to molasses in making silage.

Methane production and energy partitioning in sheep fed Andropogon gayanus grass ensiled at three regrowth stages. Can. J. Anim. Sci. 95: 103–110. This study was undertaken to evaluate the effect of harvesting Andropogon gayanus at different regrowth stages (56, 84 and 112 d) on the nutritional value of silage and CH4emissions from sheep. Rams (n=18) were adapted to silages for 21 d after which intake and digestibility were measured over 5 d in a completely randomized design (six rams/treatment). Heat production and methane emissions from each ram were measured in a respiration chamber over 24 h. Silage dry matter (DM; 54.4 g kg−1BW0.75d−1) intake was not influenced (P>0.05) by silage regrowth stage, but apparent DM digestibility linearly decreased (P<0.05) from 526 to 380 g kg−1with increasing regrowth. Energy lost as a percent of gross energy intake (GEI) linearly increased with longer regrowth, yet no effect on CH4losses (as% GEI; g kg−1DM; g kg−1digestible DM) or heat production were observed. Ensiling A. gayanus grass at an earlier regrowth stage (56 d) will improve silage quality, but improvements in the energetic value are not due to a reduction in enteric CH4emissions as a% GEI.

The bagasse has potential as an alternative feed for ruminant. However,  though the high of the crude fibre and the very low in the nutritional value make them very limited in using for animal feed. To overcome the problem in order to increase nutritional value was the fermentation technology by the application of the starbio inoculums. The objective of the research was to observe the  nutrition  qualities of the bagasse with aplication of different levels of starbio. The experimental design was  a completely Randomized Design  with 4 treatments i.e. P0 (bagasse + 0% Starbio), P1 (bagasse+ 0.2% starbio), P2 (bagasse+ 0.4% Starbio), P3 (bagasse+ 0.6% Starbio) and each treatment has 5 replication, The parameters measured were pH, dry matter (DM), crude protein (CP), ether extract (EE) crude fiber (CF), ash and Nitrogen Free Extract (NFE). The results of the research indicated that pH of the  fermentation was very good (3.37-3.67), DM (66.59-68.73%), and CP 1.47-1,97%. However, there was no effect on EE, CF, ashes and NFE. The addition of 0.6% starbio was the best result to increase CP but did not affect on ash content.

This work aimed to evaluate the fermentative characteristics silages of two varieties of sugar cane with different additives. The experiment was conducted in the Department of Agricultural Sciences of UNIMONTES, Janaúba Campus - MG. A completely randomized design with a factorial scheme of 2 x 5 + 2 was used, with two varieties of sugar cane (RB 86 7515 and IAC 86 2480) and five additives (urea, NaOH, CaO, corn and Lactobacillus buchneri), with three repetitions and one treatment without additive by variety, where the silos were opened 60 days after the ensiling. The additives NaOH and CaO promoted reductions in the losses by gases and effluents of the silages of sugar cane. The IAC 86 2480 variety showed better recovery rate of dry matter. The additives NaOH and L. buchneri reduced the water activity in the IAC 86 2480 variety. Corn and L. buchneri promoted lower pH values. The addition of urea significantly increased the amounts of ammonia nitrogen. The silages supplemented with NaOH and CaO showed high levels of lactic acid and low concentrations of ethanol. The concentration of acetic acid as a percentage of dry matter was high in all treatments. Propionic acid and butyric acid were within the ideal range for the fermentation process. The use of NaOH and CaO additives resulted in a silage with good fermentative characteristics and the best variety for the ensiling process was IAC 86 2480.

ABSTRACT Brazil is the world’s largest producer of sugarcane (Saccharum officinarum L.) and research aimed at propagation has promoted higher quality in production. The objective of this study was to investigate the effect of the variation of micrometeorological elements on the survival and quality of pre-sprouted sugarcane plantlets. The study was carried out in a protected environment (UFRPE). Plantlets of the cultivar RB92579 were obtained by the technique of production of pre-sprouted plantlets. The protected environments were divided into four modules covered with low-density polyethylene plastic + photo-selective shade nets and one module without shade net. Micrometeorological data of global and photosynthetically active solar radiation, air temperature, substrate temperature, relative humidity and the solar radiation spectrum were recorded in each module. The experiment was conducted in a completely randomized design and the principal component analysis was used to verify the association between the cultivation modules, micrometeorological variables and crop variables. Anti-UV low-density polyethylene plastic + freshnet led to lower transmittance of global solar radiation, higher percentage of photosynthetically active radiation and lower plantlet mortality. Substrate temperature above 30.2 °C resulted in higher plantlet mortality. Larger spectrum in the red range led to the production of better quality plantlet. The use of freshnet shade net promoted adequate conditions for the cultivation of sugarcane plantlets and allows obtaining better quality plantlets.

ABSTRACT Cowpea is broadly cultivated worldwide, especially in semi-arid or arid regions where soil or irrigation water salt contents can negatively influence the species’ productive capacity. The objective of this study was to evaluate the morphophysiological responses of cowpea genotypes to irrigation water salinity. The experiment was conducted in a greenhouse, under a completely randomized design with nine replications and in a 5x3 factorial scheme. Treatments consisted of five levels of irrigation water electrical conductivity - EC (EC0: 0.55; EC1: 1.60; EC2: 3.20; EC3: 4.80 and EC4: 6.40 dS m-1), applied from the 15th day after sowing (DAS), and three cowpea genotypes (G1: BRS Imponente; G2: MNC04-795F-168 and G3: MNC04-795F-159). EC increases at 35 DAS promoted stem diameter reductions of 8.0% (G1), 11.4% (G2), and 7.7% (G3), indicating different resistance to salinity by each genotype. Leaf area reductions at 25 and 38 DAS were 30.9% and 38.8% for EC0 and EC4, respectively. The BRS Imponente cultivar presented a performance superior to those of G2 and G3 in relation to stem diameter and stem dry matter at 25 DAS, and root-shoot and root-leaf ratios at 38 DAS.

ABSTRACT Competition is the best known form of direct interference of weeds on agricultural crops. However, there is relatively little information on the competition of the weed sudangrass on soybean, which has been common in agricultural areas in the southern of Rio Grande do Sul. The objective of this study was to evaluate the competition between sudangrass and soybeans using replacement series experiments. The experiment was carried out in a greenhouse in a completely randomized design with four replications. The treatments consisted of soybean and sudangrass associations. The experimental units were 8-L plastic pots, in the proportions 0: 8, 2: 6, 4: 4, 6: 2, 8: 0, corresponding to 0, 25, 50, 75 and 100% of the crop and weed respectively. Shoot, root and total dry matter and plant height were analyzed through diagrams applied to replacement series and competitive indices. Soybean showed competitive superiority in coexistence with sudangrass in relation to shoot, root and total dry matter. The intraspecific competition was more significant for the crop and inter-specific competition was more important for the weed.
