ABSTRACTObjective. This experiment was conducted to evaluate the best concentration of peanut cake in the ensiling of massai grass of the chemical-bromatological composition, fermentative characteristics, forage value rate, ingestion estimates, and digestibility of dry matter in the silage. Materials and methods. The experiment was carried out at the Experimental Farm of São Gonçalo dos Campos at the Federal University of Bahia, Brazil. The treatments consisted of massai grass that was cut at 40 days and dehydrated, in addition to 0%, 8%, 16%, and 24% peanut cake in the fresh matter and treatment without cake. The material was compressed in experimental silos (7 liter) that were opened after 76 days. Results. The addition of 8-24% peanut cake improved the silage’s chemical-bromatological parameters, increased the dry matter and non-fiber carbohydrates and reduced the fibrous components. There was a linear increase in the estimated values of digestibility and the ingestion of dry matter depending on the levels of peanut cake in the silage. There was an improvement in the fermentative characteristics, with a quadratic effect positive for levels of ammoniacal nitrogen. The forage value rate increased linearly with the inclusion of peanut cake. Conclusions. The inclusion of up to 24% peanut cake during ensiling of massai grass increases the nutritive value of silage and improves fermentation characteristics.

ABSTRACT The authors evaluated the effects of doses of organic compost on the production and accumulation of macronutrients in endive plants in two areas with different fertility levels. The experiments were carried out at Fazenda Experimental São Manuel, located in the municipality of São Manuel, São Paulo State, Brazil. The study was carried out in a completely randomized design with seven treatments, six doses of organic compost (0, 35, 70, 105, 140 and 175 t/ha) and one additional treatment with inorganic fertilizer (N-P-K 4-14-8) and four replicates. In both areas, when the dose of organic compost was increased, the authors noticed a linear increase in fresh matter weight, number of leaves and plant height. In high-fertility area, compared to control (dose 0), using the highest dose (175 t/ha), the authors observed an increase of 280, 58 and 101% in fresh matter weight, number of leaves and plant height, respectively. For dry weight, we observed a linear increase in low fertility area and quadratic effect in high fertility area, with maximum estimated dry matter of 22.26 g applying 144 t/ha of organic compost. The nutrient accumulation was proportional to dry matter, with a linear increase in low fertility area and quadratic effect in high fertility area. The decreasing order of accumulated nutrients was K>N>Ca>P>S>Mg, with the highest values, in high fertility area, of 1,269, 471, 185, 91, 53 and 35 mg/plant, respectively, for doses varying from 121 to 158 t/ha.

This study evaluated the best level of inclusion of licuri cake (Syagrus coronata) in massai grass (Megathyrsus maximus) silage by chemical composition and fermentation quality of the silage. The experiment was conducted at Experimental Farm of the School of Veterinary Medicine and Animal Science of Federal University of Bahia. The treatments were composed by massai grass cut at 40 days, chopped and added at levels 0, 80, 160 and 240 g kg DM-1 of licuri cake. After mixing, the material was compressed in experimental silos, which were opened after 76 days. The experimental design was completely randomized, with four treatments and four replications. Data were analyzed by analysis of variance and regression. The addition of licuri cake improve linear increase (P < 0.01) in the contents of dry matter, crude protein, ether extract, total digestible nutrients, pH, NH3-N, dry matter intake, digestible dry matter and forage value index in massai grass silage There was a linear reduction in the contents of ash, neutral detergent fiber, acid detergent fiber, hemicellulose and cellulose (P < 0.01). There were no differences on contents non-fibrous carbohydrates (P = 0.356) and acid detergent lignin (P = 0.432). It is recommended the inclusion of licuri cake at level of 240 g kg DM-1 in massai silage, because provided the greatest chemical composition, dry matter intake, digestible dry matter and forage value index.

This study aimed to evaluate the effects ofStreptococcus bovison the fermentation characteristics and nutritive value of Tanzania grass silage. Tanzania grass was chopped and left untreated (U) or treated withStreptococcus bovisJB1 at 1 × 106colony-forming units per gram (cfu/g) of fresh forage orStreptococcus bovisHC5 at 1 × 106 cfu/g of fresh forage and packed into sixtuplicate laboratory silos. The largest number of enterobacteria, molds and yeast (M&Y) occurred in untreated silages and the smallest populations of enterobacteria and M&Y and the largest numbers of lactic acid bacteria (LAB), at 9.81 and 9.87 log cfu/g, were observed inStreptococcus bovisJB1 and HC5, respectively (P<0.05). Silages treated with JB1 and HC5 had lower (P<0.05) silage pHs and concentrations of ammoniacal nitrogen (NH3-N) than untreated silages. The application ofStreptococcus bovisJB1 and HC5 resulted in fewer losses through gases and effluents (P<0.05), which resulted in greater dry matter recovery (DMR) and crude protein recovery (CPR) (P<0.05).Streptococcus bovisJB1 and HC5 improved the fermentative profile and increased the concentration of crude protein and DMR and CPR in Tanzania grass silage.

In the current world scenario of agriculture it is necessary to find technologies to reach high productivity that are effective in providing soil conditioning improvement for the plants. Thus, this study analyzed the efficacy of organomineral fertilizers formulated with different organic matter sources on growth factors of maize. The experiment was done in a greenhouse at Campus Umuarama, Federal University of Uberlândia-MG, in a randomized block design, as a 2 x 5 + 2 factorial, containing two sources of organic matter, biosolid and filter cake, five doses of P2O5 recommendation for the crop and two additional treatments: mineral fertilization (100% of P2O5 of the recommended dose) and a control (no fertilizer), with four replications. Plant height, stalk diameter, and chlorophyll a and b were determined at 35 days after sowing (DAS); plant height, stalk diameter, shoot and root fresh and dry matter were determined at 65 DAS. The organomineral sources with biosolid and filter cake yielded greater height and diameter at 35 DAS than those of mineral fertilization. Regardless of the fertilizer organic matter source, stalk diameter at 35 DAS presented linear increase with increasing doses of the fertilizer sources. The use of fertilizer based on biosolid resulted in greater shoot fresh matter than the filter cake source, regardless of dose applied. In general, greater results were obtained for root fresh and dry matter at the greater fertilizer doses in comparison with the mineral fertilization. Organomineral fertilizers can be a viable alternative for partial or total substitution of mineral fertilization, since similar or better results were found for maize growth characteristics.

The conservation of herbage as silages results in a reduction in the nutritive value of the crop as a result of extensive proteolysis. Measurement of the major end products of proteolysis such as ammonia and amino acids has been studied extensively e.g. Oshima el al. (1979). Considerably less attention has been given to the fate of plant proteins during ensilage (Fairbairn et al., 1988). Since this may lead to a better understanding of the mechanisms involved in proteolysis and thus to improvement in its control the present study was designed to follow changes in the major nitrogenous constituents, particularly proteins and peptides, through time course sampling of silages made from perennial ryegrass with and without additives.Perennial ryegrass (23% dry matter) was ensiled in laboratory silos (1 kg fresh matter), either untreated (UT) or treated with formic acid (FA) (ADD-F, BP Chemicals, UK: 3.3 l/tonne) or a cellulase enzyme preparation (E) (FSO-1), Forum Feeds, Finland; 0.22 1/tonne).

Dairy farms in southern Australia generally use a 2-pond system to manage dairy shed effluent. This system consists of a deep anaerobic first pond and a shallow aerobic second pond. The liquid in the second pond contains a range of nutrients that may have agronomic benefits for forages. The effect of applying second-pond dairy effluent to a summer turnip (Brassica rapa L.) crop over 3 consecutive summer periods was measured. Effluent was applied at 6 rates, 0, 15, 30, 45, 60, and 75 mm, approximately 6–8 weeks after turnips were sown each year. Turnips were assessed for dry matter (DM) accumulation, nutritive characteristics, and mineral content. In addition, total annual production for years 1 and 2 was calculated by including the DM accumulation from annual ryegrass grown from autumn to spring each year. Concentrations of nutrients within the effluent as an average over the 3 years were 31, 454, 20, and 149 kg/ML for phosphorus (P), potassium (K), sulfur (S), and nitrogen (N), respectively. In addition, effluent also contained 152 kg/ML of calcium (Ca), 225 kg/ML of magnesium (Mg), and 529 kg/ML of sodium (Na). Soil pH was generally unaffected with effluent application, while soil EC and total soluble salt (TSS) content increased with effluent addition. In the first year, application of effluent at 15 mm and higher resulted in increases in available K; however, in subsequent years, rates of 45 mm and higher led to an increase in available K, while for the control and lower effluent rates there was a marked decline in K status. In all years there was a linear increase (P < 0.05) in leaf, root, and total DM yields with applied effluent. For leaf, responses were 19, 50, and 26 kg DM per mm applied effluent and for roots, 10, 39, and 25 kg DM per mm applied effluent for years 1, 2, and 3, respectively. In years 2 and 3, turnip leaf crude protein (CP) content increased (P < 0.05) in a linear manner at rates of 0.046 and 0.044% per mm applied effluent, respectively. There was also a linear increase (P < 0.05) in turnip root CP in years 2 and 3 of 0.033 and 0.021% per mm applied effluent, respectively. In all years there was a linear increase (P < 0.05) in leaf K content, while for root K there was a quadratic trend (P < 0.05) for year 1 and a linear increase (P < 0.05) for years 2 and 3. The results from this study indicate that the use of dairy effluent can increase DM yield and improve the nutritive value of turnips through an increase in CP content. The data also indicate that this effect can be maintained over consecutive years, which in turn may provide greater flexibility for returning effluent to farm land. While results appear to indicate that the primary responses are due to N, further work is required to determine the effects of water and other nutrients within dairy effluent.

The experiment was carried out between 2010 and 2012. Effect of plants covering and the kind of organic mulch applied to soil mulching on the yield and selected component of nutritive value in Milady F<sub>1</sub> broccoli cultivated for early harvest was investigated. The application of polypropylene fibre contributed to a significant increase in the marketable yield of broccoli on average by 5.25 t/ha, weight of head by 0.10 kg and length of arc by 1.44 cm. Increase of the content of chemical components as a result of plants covering amounted to 1.76% for dry matter,&nbsp;2.50 mg/100 g fresh matter (FM) for ascorbic acid, 0.65% FM for total sugar and 0.15% FM for monosaccharides. All kinds of straw contributed to an increase in the broccoli yield and improvement its parameters. The highest marketable yield and weight of head was obtained in the plots mulched with buckwheat straw. Irrespective of covering, cultivation on the mulch with buckwheat straw contributed to a slight decrease in dry matter, total sugars content, whereas cultivation on the rye straw decreased ascorbic acid content.

Four experiments are described in which the effectiveness of SO2 as a forage treatment before ensiling was evaluated in terms of its influence on silage composition and nutritive value. Retention of added S to the time of feeding was 40% in one experiment and ranged from 17 to 32% in another experiment where SO2 was either applied in the field or at the silo. In general, more water-soluble carbohydrates were preserved in SO2-treated silage. Across all experiments the acetate concentration was reduced (P < 0.05) from 1.7 to 0.9% in the treated silage dry matter (DM). SO2 had no consistent effect on concentrations of other end products of microbial fermentation. In five experiments with legume or alfalfa-grsss silages the apparent digestibility of energy was increased (P < 0.05) by an average 2.6 percentage units whereas DM digestibility was not influenced (P > 0.05) by SO2 treatment. In contrast, energy (P < 0.05) and DM digestibilities were decreased when two cereal silages were treated with SO2. Cattle fed legume or legume-grass silage grew an average of 12.9% faster (P < 0.05) and exhibited a 12.7% improvement (P < 0.05) in DM conversion to liveweight gain in eight comparisons which have been made with SO2-treated forage to date. In contrast SO2 had no influence (P > 0.05) on the performance of steers in one 42-day trial with cereal silage. Further, SO2 was successfully applied in the field as well as at the silo and addition of a silage inoculant to SO2-treated forage was of no value. The use of SO2 as a preservative for legume and alfalfa-grass silage would be economically feasible under some circumstances but at this time treatment of cereal silages with the chemical cannot be recommended.

This study was undertaken to evaluate the effects of different row spacings and planting populations on dry matter yield, nutritive value, and predicted milk yield of BRS 658 forage sorghum hybrid growing in Brazilian conditions. A late relative maturity forage sorghum [Sorghum bicolor (L.) Moench; 110 d-115d to soft dough stage; BRS 658 – Embrapa] was planted at 3 row spacing (0.5, 1.0 and 1.5 m) and at 3 planting population (50 x 103, 100 x 103, and 150 x 103 plants.ha-1). Treatments were arranged in a randomized complete block design in a 3 x 3 factorial arrangement, using 4 replicate plots per row spacing x plant population combination. At harvest, weights of whole-plant sorghum forage were obtained to calculate DM yields. Chemical composition was assessed by performing wet chemistry analysis. Plant height, stem diameter, and harvest were performed 110 days after sowing (DAS). Estimated milk yield per unit of forage and per hectare were calculated using Milk2006. Summative equations were used to predict TDN and NEL. Yield of wet and DM forage sorghum exhibited a negative quadratic response as row spacing increased, reaching the maximum yield response at row spacing of 1.23m and 1.22m, respectively. In addition, negative linear effect was detected for both wet and DM sorghum forage yield as planting density increased. Regarding agronomic measurements, sorghum height exhibited a negative linear pattern as plant density increased. Otherwise, stem diameter increased as planting density increased. Whole-plant sorghum forage DM content decreased linearly with increasing planting density. Conversely, ashes increased linearly as planting density increased. Neutral detergent insoluble protein exhibited a positive quadratic effect with increasing planting density, reaching the minimum value when planting density was 104.2 x 103 plants.ha-1. Finally, a negative quadratic effect for predicted milk yield per hectare was also observed with increasing row spacing, whereas the maximum milk yield per hectare value was detected when row spacing was 1.20m. In conclusion, taking into account a subtropical climate, the ideal row spacing and planting density recommendation for a high yield and nutritional quality sorghum forage are 1.2 m and 104 x 103 plants.ha-1, respectively.

Production Losses

Many feeding , economic and managemental problems have been observed to be associated with the silage feeding (Wilkinson, 1990) e.g.;1) The high cost of production, losses during storage and damage to the walls and floors of silos.2) Variation in feed characteristics due to multicut.3) Effluent and pollution problems.4) The unpredictable feeding value and tendency to enhance milk fat but not milk protein in lactating animals.All these factors have forced animal scientists to look for suitable alternatives to grass silage . Whole crop cereals have drawn the attention of workers as a substitute for grass silage due to the following advantages ;1) The number of cuts and the harvesting cost can be reduced .2) A high dry matter yield of crop can be obtained with modest application of fertiliser and no effluent problem.3) The early harvesting of the crop gives more time for the entry of the following crop.4) More predictable nutritive value , high grain content ( approaching 50 % ) of the total crop yield .
