<p class="abstrak2">This experiment was carried out to determine the effect of mulberry-leucaena foliage mixed feed on protein digestibility and VFA production using an in vitro gas production study. Mulberry was mixed with one of 2 leucaena varieties (<em>Leucaena leucocephala</em> hybrid and <em>Leucaena leucocephala</em> local) at 3 levels (0, 25 and 50%). Study was conducted in completely randomized design. Mulberry foliage, leucaena and mixtures of mulberry-leucaena were incubated for 24 hours in glass syringes. Parameter recorded were gas production, in vitro true dry matter digestibility (IVTDMD), in vitro N digestibility (IVND) and VFA production. Results of the study showed that supplementation of leucaena to mulberry decreased IVOMD, gas production and protein digestibility in the rumen buffered medium. The mixture of mulberry and leucaena hybrid at ratio 50% resulted in the lowest IVND than other treatment. However it increased protein digestibility in acid pepsin incubation as an estimate of protein availability in intestine. Gas production decreased in mulberry leucaena mixtures was followed by decreased total VFA production. Tannin derived from leucaena hybrid supplementation to mulberry at ratio 1 : 1 was most effective to decrease protein digestion in the rumen and to increase protein digestibility in acid pepsin incubation. In conclusion mixing of hybrid leucaena hybrid with mulberry foliage was able to protect protein degradation from mulberry in the rumen.</p>

Abstract Background A need for research searching for alternative rumen enhancers warrants immediate attention. The in vitro fermentation experiment was conducted using factorial arrangement of two factors of roughage to concentrate and seven level of red amaranth leaf powder percentage of total substrate in a Completely randomized design (CRD). Two factors, namely Factor A was two ratio of roughage (R) to concentrate (C) at 60:40 and 40:60 and Factor B was level of red amaranth (Amaranthus cruentus, L) leaf powder (RALP) supplementation at 0, 2, 4, 6, 8, 10, and 12% of total dietary substrate. Results Red amaranth leaf powder (RALP) contained phytonutrients both condensed tannins and saponins in addition with high macro minerals (Ca, K, and Mg). This experiment revealed innovations of the RALP supplementation by enhancing rumen propionate (C3) production, reducing acetate (C2) to (C3) ratio, reducing protozoal population and mitigating methane (CH4) production. Furthermore, rumen dry matter degradation percentages were remarkably enhanced (P < 0.001) by increasing RALP supplementation. Conclusion Plants rich in phytonutrients and minerals such as red amaranth leaf powder (RALP) have a vital and promising role in modulating rumen fermentation, mitigating methane production, as well as increasing substrate degradability.

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.

Protein source feed is the feed that has the biggest share in the nutritional needs of livestock. Lamtoro or Leucaena leucocephala is one of the leaf flours that can be used as an alternative feed ingredient for poultry in the tropics. With its abundant availability and does not compete for its needs with humans and has no selling value so that it can minimize consumption costs for poultry. This study aims to determine the effect of fluid from the digestive tract of chickens on the in vitro digestibility measurement of lamtoro leaves. The study used a completely randomized design (CRD) with a unidirectional pattern with 4 treatments and 3 replications. The treatments consisted of P0 = control, P1 = gizzard fluid, P2 = duodenal fluid and P3 = a mixture of gizzard and duodenal fluid. The results of this study show the average Dry Matter Digestibility Coefficient (%) for the treatment P0, P1, P2 and P3 respectively; 19.276, 29.089, 20.515 and 28.737. Organic Matter Digestibility Coefficient ; 27.702, 36.313, 24.795 and 35.649. Dissolved Protein Digestibility Coefficient ; 39.777, 53.288, 21.145 and 48.737. The results of the statistical test that the administration of lamtoro leaves showed a significant difference (P<0.05) on the digestibility coefficient of dry matter, organic matter and dissolved protein. The conclusion is that the use of gizzard liquid is more effective in increasing the in vitro digestibility of lamtoro leaves.

Abstract This study aimed to evaluate the effects of using different types and levels of preservatives on chemical composition and in vitro gas production (IVGP) of cassava peel silage. The following treatments were applied: T0: cassava peel without preservative; T1: T0 + molasses 2%; T2: T0 + molasses 4%; T3: T0 + rice bran 2%; T4: T0 + rice bran 4%; T5: T0 + cassava meal 2% and T6:T0 + cassava meal 4% with 3 replications arranged in a completely randomized design (CRD) for the chemical composition variable and randomized block design (RBD) for IVGP variable. The results showed that treatments significantly affected (P<0.01) DM, OM, and EE contents, significantly affected (P<0,05) IVGP but did not significantly affect CP, CF contents, potential, and rate of gas production (P>0.05). Treatment T5 seems to have higher values of IVGP and ME (159.1±7.19 ml/500 mgDM; 11.1±0.36MJ/kg DM, respectively) compared to the other treatments that might have related to a higher OM available for in vitro fermentation process. It can be concluded that the use of cassava meal at 2% level can be considered as the most ideal preservative to use to produce a high-quality cassava peel silage.

Abstract The objective was to evaluate the fermentation profile, in vitro gas production and nutritional quality of pornunça (Manihot spp.) silages containing levels of condensed tannin (CT; 0, 4, 8 and 12% on dry matter (DM) basis), at five opening times (0, 3, 7, 14, 28 and 56 days). A completely randomized design in a 4 × 5 factorial arrangement was adopted, with four replications, totalling 80 experimental silos. The pH and NH3-N analyses were performed at all opening times of the silos. The other analyses were performed only with silages opened at 56 days of storage. There was an interaction effect between CT levels and silo opening times for pH and NH3-N. Tannin levels in pornunça silages after 56 days ensiling increased the pH and DM and reduced crude protein (CP) and neutral detergent fibre (NDF). There was a quadratic effect for NH3-N, acetic acid, butyric acid, gas losses, dry matter recovery (DMR), hemicellulose and acid detergent fibre. Inclusion of 4 and 8% CT in pornunça silage promotes a rapid decline in pH, being within the acceptable limit for adequate fermentation at 3 days of ensiling. Silages with 4% CT establish the pH at 28 days of opening the silos, with reduced NH3-N. Silages with 4% CT present higher concentrations of acetic and butyric acids and greater DMR. Inclusion of CT in pornunça silage after 56 days ensiling increases DM and reduces CP and NDF, directly affecting the in vitro degradability and reducing gas production.

The inclusion of multipurpose trees with grass such as Panicum maximum in the diet of ruminants may enhance productivity. Thus, the study was carried out to determine the proximate composition, in vitro gas production characteristics and parameters of Leucaena leucocephala and Panicum maximum at varying proportions. Five diets were formulated such that Panicum maximum was substituted with Leucaena leucocephala at different ratio: T1 (100% Panicum maximum), T2 (100% Leuceana leucocephala), T3 (50% P. maximum + 50% L. leucocephala), T4 (75% P. maximum + 25% L .leucocephala) and T5 (25% P. maximum + 75% L. leucocephala). Data were subjected to analysis of variance. Values obtained for dry matter (34.43 –35.95g/100g) decreased with the increased inclusion of Leuceana leucocephala in the diets. The crude fiber values (14.33 – 30.75g/100g) also followed the same trend while crude protein (CP) content (10.70 – 26.78g/100g) increased the inclusion of Leucaena leucocephala in the diets. There were significant (P < 0.05) differences in the treatment means of organic matter digestibility (OMD 31.93 – 37.07%), Metabolisable energy (ME 3.62 – 4.33 MJ/kgDM), short chain fatty acids (SCFA 0.04 – 0.16mL) and methane (ME 1.00 – 2.50 mL).The values (2.00 – 4.67 ml/200mgDM) obtained for immediate soluble 'a' was significantly (P < 0.05) different among the treatments. The extent of gas production (a+b) ranged from 2.00 – 4.67 mL/200mgDM, T1 (100% Panicum maximum) recorded the lowest while highest was observed in T2 (100% Leucaena leucocephala). The insoluble but degradable fraction 'b'ranged from 2.67 – 5.67ml/200mgDM, while the rate of gas production 'c' ranged from 0.04 – 0.14ml/hr. In conclusion, the enhanced values of crude protein, OMD, SCFA, and ME in the Panicum maximum and Leucaena leucocephala mixture indicate that the diets is able to meet the nutrients requirements of small ruminants in the tropics especially during the dry season.

The objective this study was to evaluate the effect of maniçoba supplementation in sugar cane silage with respect to chemical-bromatological composition and the in vitro degradation kinetics of the silage. This experiment was conducted in a completely randomized design with four treatments (maniçoba levels: 0, 20, 30, and 40%) and six repetitions. Silage samples were analyzed for their chemical-bromatological composition, digestible energy, metabolizable energy, total digestible nutrients, in vitro gas production and degradability parameters. The silage with higher inclusion level had better bromatological composition (p < 0.05) than the silage without maniçoba for CP, NDF, ADF and MM (6.49, 56.64, 38.66 and 4.52% versus 2.21, 70.96, 49.95 and 2.78%). Higher ME content (2.35 MJ kg-1 MS versus 1.85 MJ kg-1 MS), DE (2.87 Mcal kg-1 MS versus 2.25 Mcal kg-1 MS) and TDN (65.16% versus 51.11%), respectively. The highest values for gas production were also observed in silage with added maniçoba due to higher NFC content (34.87%). With an increase in the proportion of maniçoba, there was an increase in the soluble a fraction, b fraction, and thus a higher effective degradability of dry matter (46.56%). The addition of maniçoba improves the nutritive value of sugarcane silage.

AbstractThis study was conducted to determine the potential nutritive value andin vitrogas production (IVGP) parameters ofOlea europaea L. (Olive = OL),Morus alba L. (Mulberry = ML) andCitrus aurantium L. (Sour orange = SOL) tree leaves. Hohenheim gas test was used to determine thein vitrogas productions of the leaves. The gas production of samples over time was recorded for 3, 6, 9, 12, 24, 48, 72 and 96 h after incubation. Completely Randomized Design was used to compare gas production, and gas production kinetics of samples. The findings of the present study suggested that there were differences among the tree leaves in terms of crude protein, NDF,in vitrogas productions, organic matter digestibility (OMD), metabolisable energy (ME), net energy lactation (NEL) and relative feed values (RFV) (P<0.01). ML had the highest condensed tannin contents (P<0.05),in vitrogas production (IVGP), OMD and energy values (P<0.01). SOL had highest RFV values. OL showed the lowest IVGP when compared to SOL and ML. Low NDF and ADF contents of SOL would probably increase the voluntary intake, digestibility and relative feed values of these leaves by ruminants. In conclusion, it was determined that OL, ML and SOL used in the study have lowin vitrogas production and can be utilized as alternative roughage feed in ruminants. However, it is recommended that the results obtained from this research should be tested inin vivostudies.
