Different Levels

The influence of dietary crude fiber (CF), and the methods used in formulating high-fiber diets, on digestibility coefficients were investigated. Following a 10-wk adaptation period to the four dietary treatments, two barrows and two gilts per treatment, of an average initial weight of 67 kg, were transferred to metabolism crates. Diet 1 contained 14.1 MJ digestible energy (DE) per kg, 17.1% crude protein (CP) and 4.1% crude fiber (CF). Diets 2, 3 and 4 each contained 22% oat hulls, which were added to the diets isonitrogenously (diet 2), by simple dilution (diet 3), or isonitrogenously and isoenergetically (diet 4). The three diets contained, respectively, 9.8, 9.6 and 10.2% CF, 12.2, 12.5 and 14.8 MJ DE/kg and 17.0, 14.4 and 17.3% CP. Pigs fed diet 1 had significantly higher dry matter (DM) digestibility than those fed the higher fiber diets. Dry matter digestibility was also significantly influenced by the method of addition of CF with coefficients of 70.2, 72.8 and 65.0% for diets 2, 3 and 4, respectively. The inclusion of 11.5% tallow in diet 4 significantly improved ether extract digestibility over that obtained with diets 1, 2 and 3. Apparent digestibilities of nitrogen and amino acids were unaffected by the level of CF in the diet. Qualitative and quantitative changes in the energy and nitrogen level of diets with similar CF levels were associated with significant differences in the digestibility of CF, neutral detergent fiber and acid detergent fiber.

Fiber Diet

Four balance trials were conducted to determine the effect of the antibiotic salinomycin (SM) on nitrogen (N) and energy utilization and fiber component digestibility by swine fed low- or high-fiber diets. Treatments were corn-soybean meal control (C), 10% oat hull (OH) and 20% wheat bran (WB) diets, each with or without SM (82 mg kg−1). In trial 1A, 12 female pigs (34.6 kg) were fed the C or WB diets with or without SM for a 9-d adaptation period followed by a 5-d feces and urine collection period. In trial IB, the same pigs (50.5 kg) were fed the C or OH diets with previous fiber and SM levels reversed. Trial 2 was conducted in a similar fashion with the order of the fiber sources fed reversed (OH in trial 2A, 32.3 kg; WB in trial 2B, 44.7 kg). SM increased apparent N digestibility and N absorption (P < 0.01) in the WB trials, but also increased (P < 0.05) urine N and thus SM did not affect N retention. Although apparent N absorption was decreased (P < 0.06) by SM in the OH trials, this largely reflected a lower N intake (P < 0.02) and SM did not alter N retention. SM did not alter apparent energy utilization by pigs fed the C or OH diets, but increased the coefficients for DE and ME (P < 0.01) and dry matter (DM) digestibility (P < 0.05) of pigs fed the WB diets. Both OH and WB decreased apparent N digestibility (P < 0.01), but did not affect N retention (P > 0.10). OH and WB decreased (P < 0.01) energy digestibility. Digestion coefficients for DM, acid detergent fiber, neutral detergent fiber, cellulose and hemi-cellulose were not affected by SM, but were depressed by OH and WB (P < 0.01). Estimated DM digestibilities (calculated by difference) for OH and WB were 4.9% and 61.3%, respectively. The data indicate that SM may influence energy and N utilization in pigs fed a degradable source of fiber (WB), but not in pigs fed a low-fiber diet (C) or a diet containing a high-fiber ingredient resistant to fermentation (OH). This suggests that SM may alter microbial fermentation in the gastrointestinal tract of the pig. Key words: Swine, fiber, salinomycin, nitrogen utilization, energy utilization

This research was conducted to determine the effects of selected inoculant on the silage with different wilting times. The ryes were unwilted or wilted for 12 h. Each rye forage was ensiled for 100 d in quadruplicate with commercial inoculant (Lactobacillus plantarum sp.; LPT) or selected inoculant (Lactobacillus brevis 100D8 and Leuconostoc holzapfelii 5H4 at 1:1 ratio; MIX). In vitro dry matter digestibility and in vitro neutral detergent fiber digestibility were highest in the unwilted MIX silages (p < 0.05), and the concentration of ruminal acetate was increased in MIX silages (p < 0.001; 61.4% vs. 60.3%) by the increase of neutral detergent fiber digestibility. The concentration of ruminal ammonia-N was increased in wilted silages (p < 0.001; 34.8% vs. 21.1%). The yeast count was lower in the MIX silages than in the LPT silages (p < 0.05) due to a higher concentration of acetate in MIX silages (p < 0.05). Aerobic stability was highest in the wilted MIX silages (p < 0.05). In conclusion, the MIX inoculation increased aerobic stability and improved fiber digestibility. As a result of the wilting process, ammonia-N in silage decreased but ruminal ammonia-N increased. Notably, the wilted silage with applied mixed inoculant had the highest aerobic stability.

The Impact

Abstract In theory, supplementing xylanase in corn-based swine diets should improve nutrient and energy digestibility and fiber fermentability, but its efficacy is inconsistent. The experimental objective was to investigate the impact of xylanase on energy and nutrient digestibility, digesta viscosity, and fermentation when pigs are fed a diet high in insoluble fiber (&gt;20% neutral detergent fiber; NDF) and given a 46-d dietary adaptation period. Three replicates of 20 growing gilts were blocked by initial body weight, individually housed, and assigned to 1 of 4 dietary treatments: a low-fiber control (LF) with 7.5% NDF, a 30% corn bran high-fiber control (HF; 21.9% NDF), HF+100 mg xylanase/kg [HF+XY, (Econase XT 25P; AB Vista, Marlborough, UK)] providing 16,000 birch xylan units/kg; and HF+50 mg arabinoxylan-oligosaccharide (AXOS) product/kg [HF+AX, (XOS 35A; Shandong Longlive Biotechnology, Shandong, China)] providing AXOS with 3-7 degrees of polymerization. Gilts were allowed ad libitum access to fed for 36-d. On d 36, pigs were housed in metabolism crates for a 10-d period, limit fed, and feces were collected. On d 46, pigs were euthanized and ileal, cecal, and colonic digesta were collected. Data were analyzed as a linear mixed model with block and replication as random effects, and treatment as a fixed effect. Compared with LF, HF reduced the apparent ileal digestibility (AID), apparent cecal digestibility (ACED), apparent colonic digestibility (ACOD), and apparent total tract digestibility (ATTD) of dry matter (DM), gross energy (GE), crude protein (CP), acid detergent fiber (ADF), NDF, and hemicellulose (P&lt;0.01). Relative to HF, HF+XY improved the AID of GE, CP, and NDF (P&lt;0.05), and improved the ACED, ACOD, and ATTD of DM, GE, CP, NDF, ADF, and hemicellulose (P&lt;0.05). Among treatments, pigs fed HF had increased hindgut DM disappearance (P=0.031). Relative to HF, HF+XY improved cecal disappearance of DM (162 vs. 98g; P=0.008) and NDF (44 vs. 13g; P&lt;0.01). Pigs fed xylanase had a greater proportion of acetate in cecal digesta and butyrate in colonic digesta among treatments (P&lt;0.05). Compared with LF, HF increased ileal, cecal, and colonic viscosity, but HF+XY decreased ileal viscosity compared with HF (P&lt;0.001). In conclusion, increased insoluble corn-based fiber decreases digestibility, reduces cecal fermentation, and increases digesta viscosity, but supplementing xylanase partially mitigated that effect.

True Digestibility

In view of the large variation found in plant cell wall digestibilities with ruminants, an attempt was made to group 124 feeds into different lignification classes (clusters) on the basis of chemical characteristics. Each feed cluster was described using a structural coefficient [Formula: see text] that related the potentially digestible fiber (PDF, %) to the ratio between lignin and cell wall volume. The optimum number of clusters was determined iteratively by performing a regression of the apparent digestibility of dry matter at maintenance level (DDM1, %) against the PDF and cell soluble (SOL, %) contents of feeds. The [Formula: see text] coefficients varied from 0.05 (grains, N = 13) to 1.85 (corn silage, N = 3) and increased with the maturity of the grasses from 0.88 (legumes, vegetative cool season grasses, N = 26) to 1.33 (mature, cool season grasses, N = 19). Predicted PDF were closely correlated (r > 0.9, P < 0.01) to in vitro cell wall disappearances (IVCWD). Apparently digestible cell wall in four grasses and four legumes increased linearly with 96-h IVCWD and standard error (SE) was similar to the SE of predicted apparent digestible SOL from SOL concentrations. Assuming that similarity between SE could be also observed in larger samples, PDF and SOL were used in summative equations to predict apparent dry matter digestibility. DDM1 discounted for intake (DDM1 – 4, %) was regressed against SOL and PDF concentrations of 87 feeds:[Formula: see text]with ds and df, the true digestibilities of SOL and PDF. Estimates of ds and df were 0.98 and 0.95 for a zero-production (maintenance) level of intake, and 0.91 and 0.79 for an intake level four times maintenance. Since the true digestibility of the PDF component was only 4% – 13% lower than that of the cell soluble component, the concentration of PDF in cell wall was the major determinant in the variation in apparent digestibility of forages. Key words: lignin, neutral detergent fiber, true digestibility, cluster analysis, feeds

Abstract: The objective of this work was to evaluate the diet components - crude fiber, neutral detergent fiber, acid detergent fiber, hemicellulose, cellulose, and lignin - as internal indicators in the determination of the apparent digestibility coefficients of dry matter, gross energy, and of the nutrients - crude protein, phosphorus, and amino acids - in Nile tilapia (Oreochromis niloticus). Groups of ten juveniles (80.3±1 g) were randomly distributed in six tanks of 250 L and fed two practical diets, either of a plant-origin diet or of a plant- and animal-origin diet. Both diets were supplemented with 0.1% chromium (III) oxide (Cr2O3). Faeces were collected by the modified Guelph system. The apparent digestibility coefficients were determined by the content difference of the internal indicators, present in the diets and faeces, and compared by Dunnett’s test to those obtained by the use of Cr2O3. Cellulose was effective in the determination of the apparent digestibility of dry matter, energy, and nutrients of both experimental diets; and the acid detergent fiber was effective only for the diet composed exclusively of plant-origin ingredients. The use of crude fiber, neutral detergent fiber, hemicellulose, and lignin as digestibility indicators was inefficient for the analyzed nutrients of both diets. Therefore, cellulose is the most suitable indicator for digestibility evaluation in Nile tilapia.

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.

SUMMARY This experiment evaluated the correlation between the estimates of fecal digestibility and dry matter digestibility (DMD) and nutrients obtained using internal (indigestibles dry materiDM, neutral detergent fiber-iNDF, acid detergent fiber-iADF and acid detergent ligniniADL) and external (chromium oxide-Cr2O3, titanium dioxide-TiO2, and purified and enriched lignin from eucalyptus-LIPE®) markers and the values obtained by the total feces collection method. Twenty uncastrated male sheep, with 29.64±5.53 kg average live weight; approximately 12 months old, were kept in metabolic cages and fed diets containing untreated sugarcane-top hay or sugarcane-top hay hydrolyzed with 3 and 6% urea or 1.5 and 3% calcium oxide (CaO). There was a positive correlation (P<.05) between the fecal production estimated by the markers and via total feces collection, with coefficients higher than 90% for iDM, Cr2O3, and TiO2. The DMD and nutrients estimated with the use of markers was positively correlated (P<.05) with that obtained by total feces collection. Coefficients of correlation for digestibility obtained by total collection were higher than those obtained with Cr2O3, but close to those obtained using TiO2. The coefficient of correlation between the digestibility of protein and fiber fraction estimated with iDM and iNDF and that obtained by total collection was higher than 70%. Internal marker iDM and external markers Cr2O3 and TiO2 are effective in estimating fecal production and DMD and nutrients.

The objective was to evaluate the productivity, chemical composition, ruminal degradability of dry matter and digestibility of BRS capiaçu grass (Pennisetum purpureum Schum.) managed at five regrowth ages. A completely randomized design with ten replications was used in the BRS capiaçu elephant grass subjected to five cutting intervals (30, 60, 90, 120 and 150 days) in the summer, making a total of 50 plots with a useful area of 4 x 2 m. There were daily increases in the dry matter production in the order of 382 kg ha-1, with 49,859 kg ha-1 being produced at 150 regrowth days. The dry matter content and organic matter linearly increased (P < 0.01) at different regrowth ages. The crude protein content, in vitro dry matter digestibility and in vitro digestibility of neutral detergent fiber linearly reduced (P < 0.01) 0.037%, 0.196% and 0.256% per day, respectively. Potential degradability of dry matter decreased from 68.9% at 30 days to 44.7% at 150 regrowth days (0.194 percentage units per day). The rate of degradation of fraction B 'c' was not modified (P = 0.94), averaging 1.46% hour-1. In the cultivation of BRS capiaçu elephant grass in the summer season, in the northern region of Minas Gerais, the age for harvesting between 90 and 120 days of regrowth is recommended.

The paper reports data from four experiments (EXP). Broiler cockerels Ross 308 were allocated to 3 or 5 (EXP 4) dietary treatments comprising 300 (3 replicated pens of 100 chicks per pen), 50, 50&nbsp;or 100&nbsp;chickens. The EXP lasted 42, 38, 42 and 38 days. All basal diets contained adequate ingredients. The inclusion of 0.5% caprylic acid (CA) in diets reduced (<I>P </I>&lt; 0.05) body weight (EXP 1). The results of EXP 3 and 4 indicated that the diet supplemented with 0.25% CA and 30 mg vitamin E (total vitamin E concentration 50&nbsp;mg) resulted in similar BW like the basal diet, but the increased supplemental vitamin E to 150 mg (EXP 3) or to 100 mg (EXP 4) decreased (<I>P </I>&lt; 0.05 and <I>P </I>&lt; 0.001) BW and increased mortality. No differences were found between the fat and crude protein contents in dry matter of breast meat. Higher vitamin E doses in feed mixture significantly (<I>P </I>&lt; 0.001) increased the content of vitamins soluble in fats in breast meat – vitamin E (from 28.54 in the control to 80.28&nbsp;mg/kg of dry matter) and vitamin A (from 0.34 to 0.44 mg/kg of dry matter). The&nbsp;addition of caprylic acid significantly decreased the speed of lipid oxidation measured after 3&nbsp;(<I>P </I>&lt; 0.02) and 5 (<I>P </I>&lt; 0.05) days of storage in refrigerator at a temperature from 2.5 to 4°C. On the contrary, higher vitamin E doses and basal diet without CA supplement increased the oxidation of lipids.

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.
