Ruminal degradability of dry matter, neutral detergent fiber and acid detergent fiber of cultivars Stylozanthes guianensis (Mineirão) and Stylozanthes spp. (Campo Grande) were evaluated. Two incubations in rumen-fistulated adult bovine females were undertaken. Each incubation comprised of 25 samples of 7.0 g of each cultivar and samples were collected at 0, 6, 9, 12, 24, 36, 48, 72 and 96 hours after incubation. At a 5%/hour passage rate, Stylozanthes guianensis had 75.70, 59.01 and 76.81% effective degradability for dry matter, neutral detergent fiber and acid detergent fiber, respectively, whereas Stylozanthes spp. had 68.39, 51.93 and 58.89% for the same fractions. The lag time was different (P<0.05) only for acid detergent fiber. Stylozanthes guianensis presented higher ruminal degradability in dry matter and fiber fraction when compared to those by Stylozanthes spp. The decision to adopt one or another cultivar depends on studies that take into account the cost of deployment and maintenance of leguminous cultivar and its assets.

To evaluate the bromatological composition and ruminal degradability of dry matter (DM), crude protein (CP), neutral detergent fiber (NDF) and acid detergent fiber (ADF) of Xaraés palisade grass (Urochloa brizantha ‘Xaraes’ syn Brachiaria brizantha) under grazing in integrated crop, livestock (ICL), and forest (ICLF) systems, we conducted an in situ degradability trial in randomized blocks with three non-lactating 3/4 Gyr × 1/4 Holstein cows, provided with ruminal cannula. The management of Xaraés palisade grass was similar in both systems, differing only regarding shading in the ICLF system provided by eucalyptus trees (average 65% crown cover). Grass samples were incubated for 0, 3, 6, 9, 12, 24, 36, 48, 72, and 96 hours. Considering the passage rate 2% h-1, the Xaraés palisade grass of ICL system had greater NDF effective degradability in relation to ICLF (46.38% vs 44.98%). However, the palisade grass CP potential degradability was greater in the ICLF than in the ICL system (68.92% vs. 65.40%). The presence of trees in the pasture has effect on nutritional traits of the Xaraés palisade grass, increasing its protein content and degradability and reducing its fiber degradability.

A study was conducted to determine the effects of forage soybean cultivar on chemical composition, ensiling characteristics, and ruminal degradability of silage. Two cultivars of forage soybean (Kodiak and Mammouth) were field-grown, harvested at the R6 stage, and ensiled in mini-silos (n = 3) for 0, 2, 4, 8, 16 and 45 d. Two ruminally fistulated cows were used to determine in situ ruminal nutrient degradabilities of the 45-d silages. Both cultivars went through slow fermentation as indicated by a gradual decline in pH up to day 45 post-ensiling. Lactic acid concentration increased throughout ensiling and was higher for Mammouth than Kodiak except at day 45 post-ensiling. Analysis of the 45-d silages showed that Mammouth contained higher neutral detergent fiber (NDF, 490 vs. 444 g kg-1), acid detergent fiber (371 vs. 353 g kg-1) and acid detergent lignin (81 vs. 64 g kg-1) than Kodiak. However, crude protein (CP) concentration was higher for Kodiak than Mammouth. Mammouth silage had lower buffer soluble protein and higher neutral and acid detergent insoluble protein concentrations than Kodiak silage. Results of the in situ study indicated that Kodiak silage had greater ruminal dry matter (606 vs. 549 g kg-1), CP (828 vs. 752 g kg -1) and NDF (272 vs. 227 g kg-1) degradabilities than Mammouth. It was concluded that chemical composition and ruminal nutrient degradabilities of forage soybean silage were significantly influenced by cultivar. Key words: Soybean [Glycine max (L.)

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.

The study was planned to evaluate the effect of exogenous fibrolytic enzymes (EFE) supplementation for 56 days @ 240 mg/kg total mixed ration (TMR) on digestibility of dry matter and nutrients in dairy cows. Six dry non-pregnant cows were assigned in each treatment with and without EFE. The digestibility trial of seven days was conducted after 49 days of feeding. Dry matter and nutrients intake of cows was not influenced by EFE. The supplementation of EFE had improved digestibility of dry matter, organic matter, crude fiber, neutral detergent fiber, cellulose (p less than 0.01), as well as digestibility of nitrogen-free extract and acid detergent fiber, was also higher (pless than 0.05). The body weight gain of cows was higher on the supplementation of EFE in TMR. The study concluded that feeding exogenous fibrolytic enzymes (240 mg/kg) supplemented TMR improved digestibility of dry matter and nutrients, which was reflected as higher body weight gain in dry non-pregnant Gir and crossbred dairy cows.

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.

Due to the seasonal cycle of forage, the use of silage to feed animals provides nutrients throughout the year. However, its quality can be improved with the inclusion of additives and other products. Glycerol is a rich source of energy and present a high efficiency of utilization by animals. The purpose of this work was to evaluate the effect of glycerol inclusion on the chemical and fermentation characteristics of corn and sunflower silages. Two silage sources (maize and sunflower) were used and four levels of glycerol inclusion (0, 15, 30 and 45%) based on dry matter were carried out. The experimental design was completely randomized in a 2 x 4 factorial arrangement with five replications. The pH values and chemical composition of corn and sunflower silages were determined. In both silages there was increment of dry matter, non-fiber carbohydrates and total digestible nutrients (TDN) added to a reduction of crude protein, neutral detergent fiber and acid detergent fiber due to the glycerol inclusion. The corn silage required 45% glycerol to achieve the TDN level of the sunflower silage. The glycerol addition contributed to the increase in the nutritional value, offsetting loss of quality in the ensiling process.

The degradation characteristics of dry matter (DM), protein, neutral detergent fiber (NDF) and acid detergent fiber (ADF) of corn–sunflower intercrop silage (CSS) and monoculture corn silage (CS) prepared from whole plants, harvested at two stages of maturity, were compared using eight mature rumen-cannulated steers. The degradation characteristics were determined by incubating the silages in nylon bags for up to 72 h in the rumen of animals fed the respective silages. The degradation characteristics determined for the silages were the soluble fraction, the insoluble but degradable fractions, the rate of degradation of the degradable fractions of silage DM and protein, and the in situ disappearance of NDF and ADF after 0.5 and 72 h of incubation. The rate of particulate passage from the rumen was determined using chromium-mordanted NDF of the four silages. Values were used to estimate effectively degraded DM and protein. The rates of DM and protein degradation were highest for late-cut CSS (6.3 and 6.0% h−1, respectively) and the least for late-cut CS (2.5 and 0.8% h−1, respectively). Averaged across stages of maturity, more (P < 0.05) DM and protein were effectively degraded with CSS (57.4 and 70.1%, respectively) than with CS (48.8 and 48.7%). Degradation of NDF in early-cut CSS was lower (P < 0.05) than in CS after 72 h of incubation. ADF disappearance from all of the silages after 72 h of incubation was similar. Ruminal degradation of DM and protein in CSS was greater than in CS, which may affect efficiency of utilization of CSS. Key words: Degradation rate, effective degradability, corn silage, intercropped corn–sunflower, steers

A study was conducted to examine how lupin grains (LUPs) feeding affected nutritional intake, digestibility, growth, and carcass characteristics in kids. A total of 24 growing black kids (initial body weight (BW) = 16.4 ± 0.49 kg) were allocated to one of three diets at random. Lupin was included in the diet at a rate of 0 (control; CON), 100 (LUP100), or 200 g/kg (LUP200) of total dry matter (DM). The trial lasted for 91 days divided into 7 and 84 days to be used for adaptation and data collection, respectively. Feed intake was evaluated daily throughout the study. At the commencement and the end of the study, each kid’s body weight was measured to determine its average daily gain (ADG). On day 70, 5 kids were chosen at random from each group to investigate nutrient in vivo digestibility and N balance. At the end of the study, all of the kids were slaughtered to examine carcass features. Nutrient intakes (neutral detergent fiber, acid detergent fiber, and ether extract) were higher (p ≤ 0.01) in LUP-containing diets than in the CON diet. The average daily gain was greater (p ≤ 0.03) in diets containing lupin grains than in the CON diet. Cost of gain ($US/kg growth) was lower (p = 0.004) in kids fed diets containing lupin than the CON diet. Dry matter and CP digestibility rates were greater (p ≤ 0.03) in lupin diets. Retained N was higher (p = 0.04) in lupin-containing diets than in the CON diet. Cold carcass weight was higher (p < 0.05) for kids consuming the LUP100 diet than the CON diet. In lupin diets, carcass cut weights were higher (p < 0.05). Results of the current study indicate that feeding black kids diets containing lupin grains at 100 or 200 g/kg DM basis is cost effective and would increase profitability.

This study evaluated the chemical composition and ruminal degradability of dry matter (DM), neutral detergent fiber corrected for ash and protein (NDFap) and crude protein (CP) in byproducts of African oil palm (palm cake, kernel or fiber), macaúba (pulp cake and kernel cake), acai (acai fruit), babassu (kernel cake) and pineapple (peel, crown and bagasse silage). Nineteen rumen-fistulated sheep were kept in individual stalls, receiving a daily diet composed of elephant grass silage and corn and soybean concentrate. After preparation in nylon bags, the byproduct samples were incubated for 0, 3, 6, 12, 16, 18, 24, 48, 72, 96, 120 and 144 hours, with three replicates of each ingredient per incubation time. The divergence between the protein nutritional value and energy nutritional value, based on discriminatory variables between groups, was estimated by cluster analysis. The effective degradability of DM, NDFap and CP for the different byproducts was, respectively, 35.9, 26.9 and 59.0% for palm cake; 48.3, 34.3 and 76.4% for palm kernel; 21.1, 6.6 and 50.3% for palm fiber; 34.3, 15.0 and 52.8% for macaúba pulp cake; 58.1; 63.0 and 51.6% for macaúba kernel cake; 49.7, 49.6 and 41.8% for babassu cake; 53.4, 40.5 and 79.8% for pineapple bagasse silage; and 21.3, 17.0 and 38.9% for acai fruit. Based on their NDFap and CP characteristics, the feeds were clustered in up to four different groups.

ABSTRACT The objective of this study was to evaluate the nutritive value of sugarcane silage with or without inoculation with P. acidipropionici or L. buchneri, over three fermentation periods. The experimental design was completely randomized in a 3 x 3 inoculant by fermentation period factorial arrangement (without inoculant, inoculant 1, inoculant 2; x three fermentation periods, 10, 60, 90 days). Values of pH, dry matter (DM), crude protein (CP), neutral detergent fiber (NDF), acid detergent fiber (ADF), hemicellulose (HEM) and lignin were determined and in situ DM degradability profiles were modelled for parameters a, b and c, potential degradation (A) and effective degradability (ED). The 90 day fermentation yielded a lower pH for both inoculants. There was an interaction between inoculant and fermentation period (P < 0.05) for DM content, with a reduction in silage DM without the additive at 90 days. The CP, HEM, ADF and lignin contents of sugarcane were not influenced by the treatments. The addition of P. acidipropionici provided the lowest NDF content at 10 days and presented a higher fraction a, potential degradation and ED. At 60 days, there was no variation in soluble fraction, the control silage showed a higher fraction b, higher potential degradation and ED. At 90 days of fermentation, L. buchneri silages presented a higher fraction a, degradation rate and DE and a higher b value was obtained in the silage without inoculant. Inoculants are effective in maintaining the silage DM content and nutritional value during prolonged fermentation periods.
