Ruminal Degradability

The agricultural activity has generated a progressive amount of waste, which needs a proper treatment to avoid negative environmental impacts. At the same time, values can be added to such waste, as its use in animal feed. This research was conducted at the laboratory of Animal Nutrition, State University of Southwestern Bahia, campuses of Vitória da Conquista and Itapetinga. The objective of this study was to evaluate the effect of coffee husks on ruminant feeds by increasing doses of fibrolytic enzymes, evaluating their effects on in vitro ruminal degradability of dry matter (DM), neutral detergent fiber (NDF), and acid detergent fiber (FDA) of the coffee husk (CH). The experiment was a completely randomized design in a 2x4 factorial scheme. It compounded the following treatments: Coffee husk (CH1): 1.5% enzymes (E) and 24 h enzymatic action (EA); CH2: 3.0% (E) and 24h (EA); CH3: 4.5% (E) and 24 h (EA); CH4: 6% (E) and 24 h (EA); CH5: 1.5% (E) 48 h (EA); CH6: 3% (E) and 48h (EA); CH7: 4.5% (E) and 48h (EA); and CH8: 6% (E) and 48 h (EA), all based on dry matter. An improvement in the degradability of the nutritional parameters MS, NDF, and FDA occurred with the addition of enzymes, with 3% enzyme addition being the best level, and 24 hours, as the best action time. In addition to that, as the EA on coffee husk increased, the degradation rate decreased. Therefore, the use of enzymes can improve the digestibility of the fibrous fraction, enabling the use of the coffee husk and possibly other agroindustrial residues, thus minimizing their adverse effects on nature.

The objective of this work was to evaluate the effects of irrigation and nitrogen fertilization on the bromatological quality, forage production, and botanical and structural composition of Tifton 85 (Cynodon sp.) pastures overseeded with black oat (Avena strigosa). Four treatments were evaluated in a 2 × 2 factorial scheme (irrigated and non-irrigated × fertilized and non-fertilized), with three replicates, in a completely randomized design. In irrigated paddocks, the irrigation system was activated when the soil matric potential reached a value equal to, or higher than, 10 kPa and 135 kg N ha-1 was applied to fertilized paddocks, divided into four applications. The forage mass pre- and post-grazing, total forage production, and the botanical, structural, and bromatological composition of the pastures were evaluated. No interaction was observed between the irrigation and nitrogen fertilization factors for any of the variables and no significant differences were observed in forage mass between pre- and post-grazing or in Tifton leaf and stem percentages. Nitrogen fertilization had a significant effect on forage production, which was 2626.41 kg dry matter (DM) ha-1 higher in fertilized pastures than in unfertilized pastures. In addition, fertilization resulted in a lower percentage of dead material (6.66%), higher percentage of oat leaves (30.84%), higher leaf:stem ratio (1:45), higher crude protein content (24.13%), lower levels of neutral detergent fiber (NDF) (64.57%) and acid detergent fiber (ADF) (32.86%), and higher in vitro dry matter digestibility (73.01%) than in unfertilized pastures. The use of irrigation did not influence total forage production, however, it resulted in pastures with lower NDF (65.97%) and ADF (33.54%), and higher in vitro dry matter digestibility (73.48%) than unirrigated pastures. Nitrogen fertilization produced improvements in pasture structure, associated with higher dry matter yield and bromatological quality, while irrigation only produced pastures with lower fiber content and greater digestibility.

ABSTRACT: The inner bark or less tender sheath generated from industrial manufacture of canned babassu palm (Attalea speciosa) heart is inadequate for human consumption, often being discarded inappropriately and giving rise to environmental pollution. Accordingly, the aim of this study was to assess the intake and digestibility in sheep fed on silage of the agro-industrial co-product of babassu palm (ICBP)enriched with different additives, or on sugarcane silage. Fifteen Santa Inês sheep were distributed in a completely randomized design, consisting of five treatments and three replicates. The treatments comprised babassu palm silage enriched with broken maize (BM), broken rice (BR), cassava scrapings (CS), coffee husk combined with maize kernel (CC), and sugarcane silage (SC), all supplemented with concentrate, at a voluminous:concentrate ratio of 65:35. Silages based on ICBP and SC had similar intake of dry matter (DM), organic matter (OM), crude protein (CP), ether extract (EE), and non-fibrous carbohydrate (NFC). Increasing the additive fraction in ICBP silages favored the digestibility of DM, OM, CP, NFC, neutral detergent fiber (NDF), and total digestible nutrients (TDN). Our results indicated that silage based on additive-enriched ICBP can be used in the diet of ruminants, especially those based on broken maize and cassava scrapings that provide superior nutritional quality compared to the other silages assessed.

Lynch, J. P., Prema, D., Van Hamme, J. D., Church, J. S. and Beauchemin, K. A. 2014. Fiber degradability, chemical composition and conservation characteristics of alfalfa haylage ensiled with exogenous fibrolytic enzymes and a ferulic acid esterase-producing inoculant. Can. J. Anim. Sci. 94: 697–704. This study investigated the effects of two fibrolytic enzyme products, applied at baling alone or in combination with a ferulic acid esterase-producing bacterial additive, on the ensilage dynamics, chemical composition and digestibility of alfalfa haylage. Five replicate wrapped bales were produced with one of five treatments, including an untreated control, and one of two fibrolytic enzyme products (EN1 and EN2) applied either alone or in combination with a ferulic-acid producing bacterial additive (FAEI). No effect of treatment was observed on the neutral detergent fiber (NDF) (P=0.889) or acid detergent fiber (ADF) (P=0.065) concentrations of haylage after ensilage, but haylage produced using fibrolytic enzyme products underwent greater (P<0.018) increases in temperature following exposure to aerobic conditions. Haylages produced with fibrolytic enzyme products had a greater (P<0.001) in vitro NDF degradability (NDFD) than untreated haylage. The use of fibrolytic enzymes applied to alfalfa haylage at ensiling increased the NDFD, despite minimal effects on the chemical composition of the herbage. However, the greater aerobic deterioration of fibrolytic enzyme-treated bales indicates higher dry matter losses during aerobic exposure. The use of FAEI with fibrolytic enzymes did not further enhance the effects of fibrolytic-enzyme treatments.

Abstract Corn stover (CS) is an agricultural byproduct available in many countries for animal feed. However, due to its high lignin (L) and neutral detergent fiber (NDF) content it has a low digestibility. The production of edible fungi, using CS-based substrate, is an option to improve CS digestibility, as fungi can break down the cross-links between cell wall components. The aim of the study was to evaluate the effect of fungal treated CS from 17 species of white rot fungi: Lentinula edodes (L5, L9, LC,L15), Hericium sp (Heri) and Pleurotus djamour (Pd-Pro, Pd-UTMR) Pleurotus eryngii (Pe-PQ, Pe-MB), Pleurotus ostreatus (Po-IE202, Po-IAP, Po-Psma, Po-P14, Po-POS, Po-JP, Po-P38, Po-Sfco) on crude protein (CP), L and NDF content and in vitro dry matter digestibility (IVDMD). The composition of the substrate (C) was CS (80.55%), ground sorghum (5.98%) wheat bran (3.89%), corn gluten (4.89%), CaCO3 (3.89%) and CaSO4 (0.89%). The variables were analyzed as a completely randomized design using the MIXED procedure of SAS. Means were compared with the Tukey procedure. A significant increase (P &lt; 0.05) of CP from 10% (Po-P38) to 69% (LC) was observed, except for Pd-UTMR, Po-IAP, Po-Psma, Po-P38 and Po-Sfco that showed similar content to the C. There was a decrease (P &lt; 0.05) in the NDF from 10% (Heri) to 34% (L15) in relation to the C. The L content did not decrease in comparison with the C (P &lt; 0.05). Furthermore, 13 treatments significantly increased (P &lt; 0.05) IVDMD from 24% (Po-P14) to 42% (Pd-UTMR), except for Po-P38, Po-JP, LC and Heri in comparison with the C. In conclusion, the cultivation of white rot fungi, such as Pd-UTMR, Po-IAP, Po-Psma, LC, L9 and L15 using CS as substrate, improved CP content and increased IVDMD of CS, suggesting that which can be a good alternative for feeding ruminants.

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.

In in vitro true dry matter degradability (IVTDMD), in situ dry matter degradability, and neutral detergent fiber degradability, both in vitro (IVNDFD) and in situ (ISNDFD) techniques were used with crossbred goats to determine dry matter and neutral detergent fiber (NDF) ruminal degradability in eight forages and four industrial byproducts. Total digestible nutrients (TDN) content obtained with five different summative models (summative equations) were studied to compare the precision of estimates. All these models included digestible fractions of crude protein, ether extract, and nonfiber carbohydrates that were calculated from chemical composition, but digestible NDF (dNDF) was obtained from IVNDFD (IVdNDF), ISNDFD (ISdNDF), or by using the Surface Law approach. On the basis of the coefficient of determination (R2) of the simple lineal regression of predicted TDN (y-axes) and observed IVTDMD (x-axes), the precision of models was tested. The predicted TDN by the National Research Council model exclusively based on chemical composition only explains up to 41% of observed IVTDMD values, whereas the model based on IVdNDF had a high precision (96%) to predict TDN from forage and byproducts fiber when used in goats.

Abstract This study aimed to evaluate energetic feedstuffs regarding chemical composition, in situ ruminal degradability of dry matter (DMD), ruminal kinetics and ruminal disappearance rate of dry matter. Seven feedstuffs (treatments) were evaluated: ground corn, ground oat, ground barley, wheat bran, soybean hull, malt root and corn germ, in a completely randomized design of four repetitions each. Two bovines ruminally cannulated were used for incubation, wherein each treatment was subjected to seven periods of exposure to the rumen (0, 3, 6, 9, 12, 18 and 24 hours). Among the evaluated feedstuffs, soybean hull had the highest neutral detergent fiber (NDF) content (68.91%) and the lowest DMD at 24 h (64.91%). Ground barley and ground corn contained the lowest content of soluble fraction (SF) (26.34 and 28.7%, respectively), among which ground barley had the highest DMD at 24 h (90.48%) and therefore showed the highest rumen disappearance rate (2.50%.h-1) by combining both parameters, while the ground oat presented the highest SF (47.75%) and the lowest rumen disappearance rate (1.09%.h-1).

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.

Ruminal Degradability

The aim of this study was to evaluate the chemical composition and ruminal degradability of the dry matter (DM), crude protein (CP) and neutral detergent fiber (NDF) of fruit residues. Three fistulated sheep were held collectively in a pen, and fed daily with the studied residues in a diet consisting of canarana grass (Echinochloa pyramidalis) and a concentrate of corn and soybeans. The animals were allowed an adjustment period of seven days. The residues were dried in the sun, crushed in a forage machine, sorted using a 4.0-mm sieve, and incubated for 3, 6, 12, 24, 48, 72, and 96 h using nonwoven bags (weight 60g/m2, 14 ×12 cm²). Chemical analyses of the residues were performed using a randomized block experimental design with split plots. The cherimoya and tamarind residues showed the highest concentrations of CP (12.66% and 11.79%) the ether extract of cherimoya residue was the highest at 22.30%stands out the sour soup residue. The cashew and guava residues showed the highest levels of lignin (22.13 and 18.34%). The effective degradability of DM for the pineapple and tamarind residues to a passage rate of 5%/h were 53.04% and 42.61%, respectively. The guava, cherimoya, and cashew residues showed lower values at 19.16%, 26.86%, and 29.21%, respectively. The cherimoya, guava and pineapple residues showed the highest values of potential degradability for CP at 87%, 81%, 86.02% and 90.94%, respectively, with an average effective degradability of 50.0% at the rate of 5%/h. The pineapple (35.38%) and tamarind residues (34.49%) showed higher values of the effective degradability of NDF at a passage rate of 5%/h. Among the studied residues, the pineapple residue showed the greatest potential for use in animal feed based on chemical composition and rates of degradability.
