The Ideal

The quality of sorghum BRS-610 silages in seven stages of grain maturity, between the milky and dry stage, for determination of the ideal moment of ensilage was evaluated. The silos were open after 56 days of fermentation. The values for dry matter of silages increased from 199 to 473g/kg or from 19.9 to 47.3%, with the advance of stage maturity of grains. As for the quality of fermentation, the silages may be classified as excellent quality in every stage of maturity. The lower values of neutral detergent fiber, 539g/kg or 53.9%, and acid detergent fiber, 307g/kg or 30.7%, were observed between the milky/dough to dough/dent stages. Regression analysis indicated an increase in values of lignin - 0.3 unit por stage - and reduction in values of in vitro dry matter digestibility - -2.5 units por stage - with the advance of the grain's stage maturity. The ensilage of sorghum BRS-610 between the milky/dough and dough stage ensure very good fermentation and nutritive value of silage.

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.

Mwangi PG, Gachuiri CK, Mbugua PN. 2017. Effect of growth stage on fodder yield and quality of dual purpose sorghum. Trop Drylands 1: 100-104. Improved Dual Purpose Sorghum (IDPS) (Sorghum bicolor-Var Ikinyaruka) were yielded at six physiological growth stages to evaluate the impact of growth stage on crop and feed quality. Six treatments based on sorghum growth’s physiological stage were randomly administered to the plot in a block and replicated three times. The treatments were IDPS yielded at bloom stage (PS1), soft dough stage (PS2), hard dough stage (PS3), physiological maturity stage (stalks with grains), (PS4), physiological maturity stage (stalks without grains) (PS5), and 1 month post grain reap (PS6). The parameters monitored were Dry Matter (DM) crop, Crude Protein (CP), Neutral Detergent fiber (NDF), Acid Detergent Fiber (ADF), Acid Detergent Lignin (ADL), In vitro Dry Matter Digestibility (IVDMD) and shoot count. The highest DM crop (18.0 ton/ha) was achieved at PS4 secernated with 8.69, 12.75, 16.27 17.04 and 13.04 ton/ha for PS1, PS2, PS3, PS5 and PS6, respectively. CP reduced with maturity from 8.6 at PS1 to 7.98, 7.96, 7.61, and 6.77 to 6.72 at PS2, PS3, PS4, PS5 and PS6 respectively. NDF and ADF at PS1, PS2, PS3, PS4, PS5 and PS6 were 54.4, 60.8, 65.71, 65.93, 66.73 70.3 and 27.93, 35.96, 41.98, 41.97, 42.04, 46.05 respectively. ADL was 3.44, 5.03, 7.38, 7.39, 7.42, and 8.3 for PS1, PS2, PS3, PS4, PS5 and PS6 respectively. Highest fodder IVDMD of 60.72 was at PS1 secernated with 60.12, 54.73, 53.82, 53.56 and 45.75 achieved at PS2, PS3, PS4, PS5 and PS6 respectively. The PS3 growth stage yielded in fodder material with highest nutritive value while highest fodder yields were achieved at PS4. Reaping at PS5 supplied both fodder and grains for livestock and human consumption respectively. It was proven that crop and quality of IDPS were affected by age at reaping time.

The objective of this study was to evaluate dry mass production, fermentative parameters and chemical and bromatological composition of sunflower silage and Paiaguas palisadegrass silage in monocropped and intercropping in different forage systems. The experimental design consisted of randomized blocks, with four replicates. The treatments consisted of silage forage systems: sunflower monocropped; Paiaguas palisadegrass monocropped; sunflower row-intercropped with Paiaguas palisadegrass; sunflower inter-row intercropped with Paiaguas palisadegrass; and sunflower oversown and intercropped with Paiaguas palisadegrass, totalizing 20 experimental silos. Sunflower and Paiaguas palisadegrass were harvested at 110 days after planting at 20 cm from the soil for silage, using brush cutter. The silos were opened after 53 days of fermentation. The rows and inter-row intercropped systems contributed to increase the mass production of the ensiled material. The monocropped sunflower silage had higher values of pH, ethereal extract and acid detergent fiber and lower values of titratable acidity and dry matter, crude protein, neutral detergent fiber and in vitro dry matter digestibility values. The silages of the sunflower intercropped with Paiaguas palisadegrass in forage systems of crop-livestock integration presented better fermentative and bromatological characteristics, guaranteeing an adequate fermentative process and nutritional quality. In this way, the intercropping of these two forages potentiates the production of silage for feeding of ruminants during the period of forage shortage.

Seventy-seven cows of mixed breeds were allocated a range of pasture only or pasture/hay diets for the first 60 days of lactation. The variation in level of pasture intake was achieved by stripgrazing. The average in vitro dry matter digestibility and nitrogen content of the pasture offered was 72.0 and 3.11 % respectively, while those of the hay were 63.3 and 2.24%. The pasture alone treatments examined the effects of underfeeding on dairy cow productivity and the pasture/hay treatments established the extent to which these effects could be overcome by the use of hay as a supplement to limited pasture. After 60 days, all cows were grazed as one group at a stocking rate of 6.0 cows ha-1. Underfeeding in the first 60 days of lactation resulted in a loss of 68.3 kg milk/cow for each kg reduction in daily pasture intake, together with a decline in liveweight and body condition. When hay was offered as a supplement, it overcame the effects of underfeeding to a large extent although milk production still declined by 31.3 kg/cow for each kg reduction in daily pasture intake. There was a residual loss in milk production of 0.6 times the immediate loss for 60 days of underfeeding. The residual benefit gained from feeding hay at any level of underfeeding averaged 0.5 times the immediate benefit. Hay was unable to counteract completely the effects of underfeeding because its nutritive value for production was only half that of pasture, and the cows could not eat enough of it to overcome this. Some possible variations to these results are considered, taking into account the quality of the pasture and hay used. The economic use of hay as a supplement to limited pasture is discussed. Providing hay is used as a genuine supplement, the use of it will be economic as long as the cost of a kg of hay is less than the price paid for 0.049 kg butterfat. The limitations to this calculation are discussed.

The objective was to select from among 24 sorghum genotypes the superior ones for silage production. The study was conducted in the experimental field of Embrapa Maize & Sorghum, in the municipality of Sete Lagoas, Minas Gerais State. It used 24 forage sorghum genotypes, 21 being hybrids from the crossing of grain sorghum females and forage males (12F38019, 12F38006, 12F40006, 12F40005, 12F40019, 12F37016, 12F37005, 12F37043, 12F39006, 12F39005, 12F39019, 12F38005, 12F38007, 12F37007, 12F39007, 12F40007, 12F38014, 12F37014, 12F39014, 12F40014 e 12F38009) and three witnesses: BRS 610, BRS 655 and Volumax. It estimated productivity per area, in vitro dry matter digestibility, and assessed the bromatological and fermentation characteristics of sorghum silage. In vitro dry matter digestibility, unavailable protein in neutral detergent, neutral detergent fiber corrected for ashes and protein, acid detergent fiber, hemicellulose and lignin differed as to the genotypes tested. The pH and the ammoniacal nitrogen of the silage also showed differences between genotypes. Most of the genotypes tested are favorable for silage production, except the hybrid with higher lignin content 12F370014, and the hybrids 12F37007 and 12F370014, which showed the highest NDFap values.

Abstract The aim of this study was to assess the nutritive value of snaplage as affected by hybrid and maturity. Five corn hybrids were grown at 70,000 plants/ha on three replicate plots (5 x 5 m) in each of three blocks (21°14′ S, 44°58′ W). Hybrids were harvested at target maturity stage of 40, 35, and 30% of moisture (M1, M2, and M3, respectively) by removing ears from two rows in each plot. Ears were weighed and split into two subsamples. One was split into kernels, husk and shank, and cob, weighed and oven-dried. The second subsample was processed and ensiled in 5-L jars for 90 d. Measurements included dry matter (DM) yield, nutrient analysis and in vitro digestion of neutral detergent fiber (NDF-D, 48h). The experimental design was randomized complete blocks using a mixed repeated-measures model. Data were analyzed using MIXED procedure of SAS, followed by a Tukey test at P ≤ 0.05. Mean moisture at harvest were 42.9, 36.8, and 31.3% for M1, M2, and M3, respectively. The DM yield was unaffected by hybrid and maturity (on average = 19 t/ha). The NDF concentration of husk increased at each maturity (81.5, 83.4, and 83.7% DM, respectively) and NDF-D decreased (45.5, 43.4, and 41.4%, respectively). The NDF concentration of cob increased at each maturity (76.0, 79.5, and 81.6% DM, respectively) and NDF-D decreased (47.3, 43.7, and 38.4%, respectively). Among hybrids, NDF concentration of snaplage varied from 20.9 to 24.5% DM (P = 0.014). The NDF-D of snaplage decreased at each maturity (Figure 1; P = 0.001). The starch concentration of snaplage increased from M1 to M2, but no difference between M2 and M3 (P = 0.009). Snaplage has a wide harvest window; however, changes in the nutritive value of snaplage as affected by maturity should be considered when formulating diets.

The agronomic performance and nutritive value of Mucuna legume (Stilozobium deeringianum (Bort) Merr.) in five stages were evaluated under climatic conditions of Peruvian central coast to estimate optimum stage of use. Five cutting ages were: 21, 42, 63, 84 and 105 days. Crop growing, forage yield, chemical composition, vitro dry matter digestibility and net energy for lactation of Mucuna were evaluated. The optimum cutting age was 84 days with 25633.3 kg. Ha-1 of fresh matter and 6422.6 kg-1 ha-1 of dry matter. In this age crude protein, neutral detergent fiber and acid detergent fiber and in vitro dry matter digestibility contents were 14.94%, 44.80%, 33.15% and 66.12 %. Net energy for lactation was 1.43 Mcal.kg-1. These results show that Mucuna was well adapted to Peruvian Central Coast with high forage yield and nutritive value.

Objective: This study was conducted to investigate the effects of wilting and microbial inoculant treatment on the fermentation pattern and quality of Italian ryegrass silage.Methods: Italian ryegrass was harvested at heading stage and ensiled into vinyl bags (20 cm×30 cm) for 60d. Italian ryegrass was ensiled with 4 treatments (NWNA, no-wilting noadditive; NWA, no-wilting with additive; WNA, wilting no-additive; WA, wilting with additive) in 3 replications, wilting time was 5 hours and additives were treated with 10<sup>6</sup> cfu/g of <i>Lactobacillus plantarum</i>. The silages samples were collected at 1, 2, 3, 5, 10, 20, 30, 45, and 60 days after ensiling and analyzed for the ensiling quality and characteristics of fermentation patterns.Results: Wilting treatment resulted in lower crude protein and <i>in vitro</i> dry matter digestibility and there were no significant differences in acid detergent fiber (ADF), total digestible nutrient (TDN), water-soluble carbohydrate (WSC), ammonia content, and pH (p>0.05). However, wilting treatment resulted in higher ADF and neutral detergent fiber content of Italian ryegrass silage (p<0.05), and the WNA treatment showed the lowest TDN and <i>in vitro</i> dry matter digestibility. The pH of the silage was higher in the wilting group (WNA and WA) and lower in the additive treatment group. Meanwhile, the decrease in pH occurred sharply between the 3-5th day of storage. The ammonia nitrogen content was significantly lower in the additive treatment (p<0.05), and wilting had no effect. As fermentation progressed, the lactic and acetic acid contents were increased and showed the highest content at 30 days of storage.Conclusion: The wilting treatment did not significantly improve the silage fermentation, but the inoculant treatment improved the fermentation patterns and quality of the silage. So, inoculation before ensiling is recommended when preparing high quality of Italian ryegrass silage, and when wilting, it is recommended to combine inoculation for making high quality silage.

This study evaluated the nutritional value of sugarcane varieties in relation to nitrogen fertilization. The varieties studied were RB 863129, RB 867515, and RB 92579, and nitrogen fertilizer was applied at doses of 0, 60, 80, 120, and 140 kg N ha-1. The experiment was divided into two stages: i) Year I - plant cane, when the yield and nutritional quality of the three sugarcane varieties were evaluated; ii) Years II and III, when and the effect of nitrogen fertilization on the nutritional quality of the first and second ratoon crops of the same varieties was evaluated. In plant cane the yield (t ha-1) and DM (dry matter) and CP (crude protein) contents were higher for the RB 863129 variety. There was no difference between the varieties regarding their NDF (neutral detergent fiber) and ADF (acid detergent fiber) contents and IVDMD (in vitro dry matter digestibility). In the first and second ratoon crops, there was a difference between the varieties and fertilizer doses for the evaluated parameters, with the exception of the DM content and IVDMD, which were influenced by the varieties, doses of N, and cutting years. The RB 92579 variety showed the best yield of the two ratoon crops (131 t ha-1 of stems) and the best nutritional parameters (26% ADF, 41% NDF, 2.4% CP, and 69.4% IVDMD). The sugarcane yield and its nutritional quality can be influenced by the cutting year and nitrogen fertilization management system and by the variety type.

The Impact

Dairy production plays a fundamental role in the Brazilian economy and high-quality forage is necessary for ruminants to produce satisfactory milk levels. The aim of the present study was to evaluate the production and quality of Jiggs bermudagrass and its effects on the production and quality parameters of milk from Holstein cows under an intermittent grazing system throughout the year. The experiment was conducted in a randomized design with the four seasons as treatments, replicated five times. The season had a significant effect on the production and nutritional parameters of Jiggs bermudagrass with the highest total dry matter production observed during summer, followed by spring and fall. The neutral detergent fiber and acid detergent fiber contents were significantly higher in winter. The in vitro dry matter digestibility was significantly higher in summer, spring, and fall. Jiggs bermudagrass is a promising forage for the enhancement of milk production under intermittent stocking. However, its effects vary seasonally which exerts a greater influence during the winter, even with irrigation, because it directly affects the milk production and quality. The correlation results demonstrated the importance of better quality forage for increasing milk production without compromising the levels of milk solids.
