ABSTRACT Coffee pulp is produced in large quantities, and its disposal can pollute the environment. However, the nutritional value and antioxidant content of coffee pulp make it a good option for animal feed. Therefore, the objective of this study was to determine the chemical composition, the phenolic compounds and the antioxidant capacity of coffee pulp using fresh (FCP), ensiled (ECP), and ensiled and sun-dried (EDCP) coffee pulp. The study design was completely randomized with three treatments (n=4). Dry matter (DM), crude protein (CP), ash, acid detergent fiber (ADF), neutral detergent fiber (NDF), lignin, phenolic compounds and antioxidant capacity were determined. Data were analyzed by analysis of variance, and means were compared with the Tukey test. The percentage of CP, NDF and ADF was higher in ECP and EDCP than in FCP. There were no changes in lignin content. Ensiling and sun drying did not decrease (P>0.05) caffeine or tannins. No differences were found in caffeic acid (2.031±2.873, 5.103±0.391, 4.913±0.018 mg g-1 DM in FCP, ECP, EDCP, respectively). The concentration of chlorogenic acid (FCP 2.593±1.756; ECP 5.368±0.422; EDCP 4.875±0.678 mg g-1) increased with the ensiling process, but it was not affected by sun drying. Ethanol decreased in ECP and EDCP relative to FPC (FPC 15.88±0.97%; ECP 7.04±1.16%; EDCP 0.00%); however, antioxidant capacity was not affected. It was concluded that the ensiling process and sun drying affected the nutritional value of coffee pulp but not its antioxidant capacity.

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.

Squash (Cucurbita sp.) is widely used in Colombia as both food and animal feed. However, its seeds are discarded. This study  aimed to identify squash genotypes with a high nutritional value in the whole seed meal (WSM) and defatted seed meal (DSM) within a group of 19 introductions (14 of Cucurbita moschata and 5 of C. sororia). For WSM, 70% of the introductions presented above-average values for extract (36.9%) and crude protein (26.34%); the fiber values were 20.34% neutral detergent fiber (NDF) and 13% acid detergent fiber (ADF). For DSM, 57% of the introductions presented above-average crude protein (43.5%) and 52% above-average crude energy values (4078 cal g-1).  Based on the relative feed value (RFV), introductions 1229, 1200, 1201, 1219 and 1206 were selected for WSM, and 1206 1229, 932, 1200, 786 and 954 were selected for DSM. In the selected C. moschata introductions, parents with general and specific combining abilities for ether extract and crude protein in WSM or high RFV in DSM should be identified. C. soraria introductions 1202 and 954 should be used in crosses that aim to obtain F2 segregants for seeds with a high oil content and high RFV in DSM.

Sorghum Genotypes

This study aimed to evaluate the agronomic performance of 24 sorghum genotypes in four Brazilian regions and the chemical characteristics of genotypes grown in Sete Lagoas, state of Minas Gerais. Genotypes BRS655 and 12F37005 had higher average production of green matter (> 44 ton ha-1) and dry matter (> 17 ton ha-1), respectively. Genotypes 12F38019, 12F40019, 12F37005, 12F37043 and Volumax took more days to flower in three of the four municipalities (75-90 days). Genotypes 12F38006, 12F40006 and 12F37016 were taller (> 2 m). Values of dry matter, crude protein and neutral detergent fiber ranged from 37.15 to 50.13; 5.51 to 10.28 and 43.57 to 65.69%, respectively. The genotypes were not different regarding acid detergent fiber content, with mean value of 34.83%. Genotypes 12F38019, 12F37016, 12F39005, 12F39019, 12F37007, 12F37014, 12F39014 and BRS 655 showed the best values of dry matter digestibility (64.31 to 74.20%) and crude protein content (8.33 to 10.28%). Among them, 12F139014 exhibited the lowest lignin content (3.32%), suggesting less effect of this fraction on digestibility. Genotype 12F39014 is the most suitable for cultivation, as it presented the best nutritional value and good dry matter production in the four municipalities.

Objectives: To determine the chemical composition and in vitro digestibility of Acacia angustissima, Dalea spp., Desmodium spp., Leucaena leucocephala, Phaseolus vulgaris and Tephrosia vicioides (Fabaceae) fodder species. Design/Methodology/Approach: Crude protein (CP), neutral detergent fiber (NDF), acid detergent fiber (ADF), crude lignin (CL), cellulose (Cel), hemicellulose (Hcel), cellular content (CC) and in vitro dry matter digestibility (IVDMD) were determined. The design was completely random with three repetitions. The variables were correlated by pairs and the means of the species were compared with Tukey’s test (P<0.05). Results: Dalea spp. had the highest crude protein (17.7%), followed by A. angustissima (15.9%) and L. leucocephala (14.1%). A. angustissima (73.2%), Dalea spp. (74.9%) and P. vulgaris (77.5%) showed the highest IVDMD. L. leucocephala, Tephrosia vicioides and Desmodium spp. showed the lowest values of CP (14.1, 11.8 and 12.3%, respectively) and IVDMD (70.4, 70.2 and 64.9%, respectively). Desmodium spp. showed high levels of NDF (59.2%), ADF (41.4%), CL (17.5%), Cel (29.7%) and Hcel (17.8%) (P?0.05). IVDMD showed positive correlation with CC and negative correlations with NDF, CL, and Hcel (P<0.05). Study Limitations/Implications: Desmodium spp. showed high content of CL and low values of CP and IVDMD, therefore supplements should be added when used in animal feed. Findings/Conclusions: Dalea spp. showed low levels of lignin and high levels of protein and digestibility, making it posible to use as feed for ruminants

Abstract: The objective of this work was to assess the nutritive value of four elephant grass (Pennisetum purpureum) genotypes. The chemical composition, intake by sheep, and digestibility of different genotypes (G1, G2, G3, and G4) were evaluated. A dry matter (DM) digestibility assay was performed with total leftovers and feces collected from 20 sheep kept in metabolic cages. G3 had lower DM intake in grams per animal per day compared with G1 and G2, and it had greater digestibility, crude protein, neutral detergent fiber, and acid detergent fiber values. G1, G2, and G4 have the best nutritive values among the evaluated genotypes.

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.

An experiment, divided into three trials, was conducted to determine the chemical composition, in vitro degradability, and ingestive selectivity of the tropical legumes (TL) Stylosanthes guianensis (Stylo; SG), Cajanus cajan (pigeon-pea; CC) and Arachis glabrata (rhizome perennial peanut; AG). In the first trial the organic matter (OM), inorganic matter (IM), crude protein (CP), neutral detergent fiber (NDF), acid detergent fiber (ADF, hemicelulose), cellulose, lignin and acid detergent insoluble nitrogen (ADIN) content in the whole plant and botanical components (stems and leaves) of the three TL were determined. The second trial evaluated the in vitro apparent (AIVDMD) and true dry matter degradability (TIVDMD) of the three TL during 48 h of incubation in bovine and caprine ruminal fluid. Trial three, of cafeteria type, evaluated the voluntary intake by goats and heifers of the three TL during one hour. In all trials tropical grass hay (HG) was used as control forage. A qualitative scale (none, low, medium and high) was used to express the intake of TL and GH. Organic matter content was lower (P < 0.05) but IM was higher (P < 0.05) in AG than in CC, SG, and GH. In all three TL, the CP content was higher (P < 0.05) than inTG, but NDF was lower (P < 0.05). AmongTL species, CP content was higher (P < 0.05) in AG than in SG and CC, but NDF content was similar. ADF content was also lower (P < 0.05) in AG than in CC and in SG, but hemicelulose percentage was higher (P < 0.05). Lignin was lower (P < 0.05) in GH than in the three legumes, and CC showed the highest (P < 0.05) ADIN content among the forages evaluated. For all three TL, CP in leaves was higher than 20%. Leaf NDF content was lower (P < 0.05) in CC than in AG and in SG, whereas ADF was higher (P < 0.05) in SG than in AG and CC. Leaves of AG also had higher (P < 0.05) hemicelulose but lower (P < 0.05) cellulose values than CC and SG. Lignin content was similar in leaves of the three TL, but ADIN content was higher (P < 0.05) in CC. Crude protein content of stems was lower (P < 0.05) in CC than in AG and SG.The NDF content and its fractions (ADF, cellulose and hemicelulose) were lower (P < 0.05) in AG stems than in those of SG and CC.The highest (P < 0.05) lignin content and lowest (P < 0.05) ADIN content were observed in CC and SG stems, respectively. In the second trial, use of either ruminal inoculum type gave AIVDMD and TIVDMD values that were, in descending order, highest (P < 0.05) in AG than in SG, GH and CC. In trial three a greater intake was observed in goats and heifers offered AG and GH than when offered SG and CC. Based on nutrient content, in vitro dry matter degradability, and voluntary intake, AG showed greater potential as a forage source than SG and CC. However, all three TL showed promise as potential alternatives for use as an integral part of ruminant feeding systems in the tropics.

Abstract Silages from four amaranth varieties (A5, A12, A14, and A28) were compared with corn silage (CS) in terms of their yield, chemical composition, phenolic compounds, oxalic acid and nitrate levels, silage fermentation characteristics, in vitro methane production, organic matter disappearance (OMD), microbial crude protein (MCP), ruminal ammonia (NH3-N), pH, volatile fatty acids, cellulolytic bacteria numbers, protozoa counts, and in situ dry matter (DM) and crude protein (CP) degradability were determined. Forages were harvested 93 d after planting, chopped, and ensiled in plastic buckets for 60 d. The study was based on a randomized complete block design, and data were analyzed using SAS, general linear model (GLM) procedure for normal distribution. Compared with CS, amaranth silages (AMS) had lower ash-free neutral detergent fiber nitrate, OMD (P &lt; 0.001), phosphorus (P = 0.003), and metabolizable energy (ME) (P = 0.043) but higher (P &lt; 0.001) CP, calcium, non-fiber carbohydrates (NFC), acid detergent lignin, ether extract, ash, total phenolics, pH, NH3-N concentration, MCP, digestible undegradable protein (DUP), and metabolizable protein (MP). Fresh, OM, OMD, ME (P &lt; 0.001), and DM (P = 0.032) yields of AMS from different varieties were higher than CS, with the exception of A5. Overall, amaranth made good quality silage, with some variation, and A28 had the highest yield and nutritional value (CP, NFC, MCP, DUP, and MP). The yield, CP concentration, and nutritional value of A28 silage were higher than CS. Although these in vitro results are promising, they also need to be validated with future in vivo research.

The objective of this study was to determine the nutritional value of three leguminous trees heavily selected by goats in a xerophilous shrubland. Chemical composition and in vitro dry matter disappearance (IVDMD) of leaves and pods from leucaena (Leucaena leucocephala), mesquite (Prosopis laevigata), and huisache (Acacia farnesiana) is presented. Crude protein (CP) ranged from 17.3% for leaves of huisache to 21.9% for leucaena. The neutral detergent fiber (NDF) content ranged from 39.0 to 40.3 with no difference among fodder threes. Across tree species, mean IVDMD was 61.6% for pods and 52.2% for leaves. IVDMD for leaves was highest (p < 0.01) for leucaena (54.9%) and lowest for huisache (47.3%). Condensed tannins in an acetonic extract were highest for leaves of huisache (45.3 mg CE/g DM) and lowest for mesquite (25.9 mg CE/g DM). Pods and leaves of huisache presented the highest number of secondary metabolites, mainly related to hydroxybenzoic acid and flavonols; leucaena and mesquite presented mainly flavonols and anthocyanins. It was concluded that leaves and pods of leucaena, mesquite, and huisache constitute valuable forages for ruminant livestock due to their low fiber, high CP levels, moderate in vitro fermentation characteristics and high mineral content.

Nitrogen fertilization can be used to increase production for area, as well as to improve the grains nutritional value. The aim of this study was to evaluate the chemical composition of two linseed cultivars (Brown and Golden) submitted to increasing doses of nitrogen fertilization in a completely randomized design. The Brown and Golden flax sowing was in April 2014, using 40 kg of viable seeds ha-1 and 100 kg ha-1 of diammonium phosphate (16-46-00) as fertilizer. It was evaluated the increasing doses of N fertilization in the cover: 0, 50, 100, 150 and 200 kg of N ha-1, applied in the urea form. For the fatty acids (FA) analysis, a composite sample of each variety was performed for the treatment 0 and 200 kg N ha-1. The composite samples were grounded in a multi-use mill with cooling jacket. The cooling was aimed to avoid the heating of the samples during their processing, in order to reduce the chances of FA profile alterations. The application of nitrogen positively influenced the production of grains and oil ha-1 of the cultivars, improved the Brown flax dry matter in vitro digestibility and the Golden flax neutral detergent fiber, ether extract and crude protein amounts. The cultivar Brown flax presented higher production of grains and oil ha-1 when compared to Golden flax, which presented lower neutral detergent fiber, crude protein, total carbohydrates and higher amounts of ether extract. The Golden flax was nutritionally healthier, as it presented higher proportions of C18:3 n3, unsaturated fatty acids, unsaturated/saturated fatty acids and hypocholesterolemic index. Both cultivars have potential ingredients to be used in animal feed, aiming to improve the quality of the final product.
