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.

Inclusion Level

The aim of this study was to evaluate the fermentative losses and nutritional value of elephant grass silages with the increasing of inclusion levels of dehydrated banana peel. The experiment was conducted in a completely randomized design, with six treatments and four replications, being the silage exclusively from elephant grass, and five levels of inclusion of banana peel to the elephant grass silage, as the following - 5; 10; 15; 20 and 25%, being added based on natural matter. The addition of the banana peel in the silage reduced linearly (p < 0.05) the pH, the ammoniacal nitrogen and the losses of the fermentative process. In addition, the inclusion of banana peel increased linearly (p < 0.05) the dry matter and non-fibrous carbohydrates. On the other hand, the neutral detergent fiber and the acid detergent fiber were linearly reduced with the inclusion of the banana peel (p < 0.05), but there was no change in the dry matter digestibility in situ. The inclusion of dehydrated banana peel in elephant grass silage reduces the losses of the fermentation process with more consistent results at the 25% inclusion level, however, it reduces the silage nutritional value due to fibrous and protein quality.

The objective of this research was to evaluate the effect of three concentrations (3, 6, and 9%) of forage turnip (Raphanus sativus) and physic nut (Jatropha curcas) cakes on dry matter, crude protein, ether extract, neutral detergent fiber, acid detergent fiber, lignin, acid detergent insoluble nitrogen neutral detergent insoluble nitrogen contents, in vitro dry matter digestibility, pH values and concentrations of N-NH3 in elephant grass silages. It was used an entirely randomized design in factorial arrangement [(2×3)+1]. Experimental PVC silos were used and ensiled material was kept for 62 days. The addition of cakes increased the dry matter contents (P<0.05). The fibrous fractions were reduced (P<0.05) with the inclusion of cakes during the grass ensilage and the CP contents increased (P<0.05). The forage turnip cake provided the same pH and N-NH3 values in ideal levels and the physic nut, added to 9%, increased those values (P<0.05). IVDMD was reduced (P<0.05) when the cakes were added. These co-products can be used in small amounts for elephant grass ensilage in order to provide improvement in chemical and fermentation characteristics of the silages. Nevertheless, physic nut cake shows limitations for its use in animal feeding due to the presence of toxic compounds, making necessary studies for their identification and elimination.

This research was conducted to evaluate 16 corn varieties cultivated for silage. The evaluation included: fodder production of green and dry matter, protein content and in vitro dry matter digestibility (IVDMD) and organic matter digestibility (IVOMD). A completely randomized design was used for statistical analysis and Tukey mean separation was used when appropiated. Fodder production as kg/ha was higher for AN446 (114028), AN445 (110993), and AN430R (106389). Dry matter fodder production was higher for AN447 (29270), AN461 (28026), VS373 (25434). Protein content (%) was higher for G4657 (7.58), AN388 (7.28), and AN448 (7.17). The best values for IVDMD (%)were for G1990 (69.14), AN446 (63.78), and AN430RR (63.50), while the higher values for IVOMD (%) were for G1990 (71.78), AN446 (65.20), and AN447 (65.12). Varieties AN446 and AN447 appeared frequently with the best values in the parameters evaluated, therefore, new research has to be performed with these varieties to confirm results found in this study.

Abstract The objective of this study was to determine the in vitro dry matter digestibility (IVDMD), gas production and pH of silages of 10 maize hybrids in Iturama, Brazil (XB 6012 BT, BM 709 VT PRO2, BM 815 VT PRO2, DKB 363 VT PRO3, AG 8740 VT PRO3, SYN 555 VIP3, SX 8555 VIP3, SX 7005 VIP3, DKB 390 VT PRO3, and RB 9789 VIP3). The maize was ensiled in experimental mini silos in a completely randomized design with 3 repetitions. After 120 d, a subsample from each mini silo was taken and the IVDMD was estimated using Ankom Daisy II and F-57 bags (n = 44). Rumen fluid from two cannulated Nellore steers were mixed and placed into fermenter jars containing Ankom buffers (1:4; v/v). After 48-h incubation (39ºC), 40 mL 6 N HCl and 8 g pepsin were added to each jar and incubated for another 24 h. For gas production and pH evaluations, penicillin-type glass vials (n = 40) were filled with McDougall buffer (20 mL), rumen fluid (10 mL) and substrates (200 mg) and incubated in a shaker (39ºC) for 24 h. The cumulative pressure was measured, vials were opened, and terminal pH was measured. Data were analyzed using the MIXED procedure of SAS. The DKB 363 VT PRO3 presented the greatest IVDMD (84.9%, P = 0.02) and the lowest pH (6.60, P = 0.002). The opposite was observed for DKB 390 VT PRO3, which presented the lowest IVDMD (71.1%) and the greatest pH (6.65). The BM 709 PRO2 produced more gas than the others (246.1 mL/g DM), while SYN 555 VIP3 produced less gas than the others (167.7 mL/g DM, P = 0.0005). In conclusion, the material DKB 363 VT PRO3 presented the most interesting characteristics for use as silage for beef cattle in Iturama, Brazil.

SUMMARY This study aimed to verify the influence of months on chemical composition and in vitro digestibility of pasture and forage selected by goats in the semiarid region of Brazil’s Pernambuco state. Six male goats fistulated in the rumen were used in a completely randomized design. Forage collection was conducted in herbaceous and shrub/tree layers, in order to simulate goat grazing, and materials were separated into leaves and branches. Extrusa and pasture collections were held in November, January and February/March. There was collection month (P <0.05) effect for pasture on dry matter (DM), crude protein (CP), neutral detergent fiber (NDF), acid detergent fiber (ADF), with average values of 458.27g/kg NM and 155.46, 521.30 and 390.13g/kg DM, respectively. For the stem (P <0.05) for DM, Organic matter (OM), mineral matter (MM), ethereal stratum (EE), ADF, acid detergent unavailable protein (AIP), total carbohydrates (TCHO) and dry matter in vitro digestibility (DMIVD), with average values of 487.47g/kg NM and 930.80, 69.07, 20.67, 440.30 and 63.78g/kg DM, respectively. About the extrusa, there was collection time effect (P <0.05) on the DM, OM, MM, CP, EE, AIP, TCHO, Non-fibrous carbohydrates (NFC) and DMIVD, with average values of 84.53g/kg DM, 863.03, 136.97, 152.90, 33.60, 14.07, 676.37 and 55.35g/kg DM, respectively. Rainfall changes in the rainy season in the caatinga altered pasture quality, causing changes in the diet selected by goats, mainly in DM, CP, CNF and DMIVD.

The objective of this study was to evaluate the effects of regrowth age (RA) and cutting time (CT) of elephant grass (Cenchrus purpureus cv. Cameroon) on the fermentation profile, microorganism population, and nutritive value of the silage in two simultaneous trials at different sites. A 2 × 2 factorial scheme with two CTs (08:00 and 14:00) and two RAs (8 and 16 weeks) at ensilage was used in a completely randomized design, with four replicates in each trial, totaling 16 experimental units per trial. Results showed that ammonia nitrogen to total nitrogen content (N-NH3/TN) ranged from 71.8 (14:00; 16 weeks) to 137.0 g kg -1 (14:00; 8 weeks). Elephant grass silage harvested at 14:00 at 8 weeks had the lowest pH (3.53) and highest lactic acid content (39.7 g kg-1 dry matter). The in vitro dry matter digestibility (IVDMD) was higher (P < 0.05) in the silage of plants harvested at 8 weeks than in the silage harvested at 16 weeks (59.9 vs. 46.8%, respectively). In trial 2, elephant grass silage harvested at 14:00 had lower pH and acetic acid content. The IVDMD was higher in elephant grass silage harvested at 14:00, with values of 65.3% and 56.2% at 8 and 16 weeks, respectively. We recommend elephant grass harvested at 8 weeks of regrowth and cut at 14:00 to produce silage with better nutritive value and fermentative profile.
