ABSTRACT This study aimed to evaluate the effect of different Clitoria fairchildiana tree shading levels on the Tanganyika grass (Megatyrsus maximus Jacq. cv. Tanganyika) chemical composition, in summer I (2011/2012), spring (2012) and summer II (2012/2013) seasons. For this purpose, an experiment was conducted in a completely randomized design with four treatments (shading levels) and five repetitions at Seropédica, state of Rio de Janeiro, Brazil. The following variables were evaluated: dry matter (DM), crude protein (CP), neutral detergent (NDF) and acid detergent (ADF) fiber, neutral (NDIP) and acid (ADIP) detergent insoluble protein, lignin (LIG) and mineral matter (MM) contents. Data were analyzed by PROC MIXED SAS®, with repeated measures in time, and treatment means compared by Tukey’s test (P<0.05) or by PROC REG (P<0.05 for regression analysis. There was a significant interaction between season and shading level for DM, CP, NDF, ADF, NDIP, ADIP and MM contents (P<0.05). Lignin content was only influenced by shading level (P<0.05). The DM, NDF, ADF and lignin contents were reduced by shading increase while CP, NIDP and MM contents were increased. Higher ADIP contents were found only in the spring. The increase in Clitoria fairchildiana tree shading improves the chemical composition of Tanganyika grass forage during summer season.

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.

The objective of this study was to evaluate the chemical composition, pH and rumen degradability of banana tree pseudostems pre-dried and ammoniated with different doses of urea (0, 0.5, 1.0, 1.5 and 2.0% in natural matter). The experiment consisted of five treatments (doses of urea) with six replications, following a completely randomized design. There was a linear increase in the pH (P < 0.01) of the banana tree pseudostems pre dried with the inclusion of urea. There was no difference (P > 0.05) in dry matter, ash, neutral detergent fiber, acid detergent fiber, lignin, non-fibrous carbohydrates and total digestible nutrients; the averages were 31.58, 18.82, 46.43, 9.30, 11.87 and 42.52%, respectively. The inclusion of 2% urea increased the crude protein content (P < 0.01) by 42.75%, the soluble fraction "a" by 31.82%, and the potential and effective degradability of dry matter by 15.49% compared to that of the control group (without urea). The potentially degradable fraction, time of colonization and ruminal repletion of the neutral detergent fiber of the pre-dried banana tree pseudostems were not altered with the inclusion of urea (P > 0.05). The ammonization of the pre-dried banana tree pseudostems with 2% of urea improved the chemical composition and rumen degradability of the dry matter.

The study aims to determine the chemical composition and digestibility of midrib palm leaves from bioconversion results. Solid bioconversion using white oyster mushroom inoculum as a starter. This study used a completely randomized design (RAL) with 6 treatments and 3 replications. As a treatment  the white oyster mushroom inoculum consisted of 6 levels, namely 0g (with inoculum), 5g, 10g, 15g, 20g and 25g kg-1 substrate. The variables measured are the chemical composition and digestibility of nipah leaf midrib fiber bioconversion products. The results showed that organic matter content, ADF digestibility and nipah leaf midrib cellulosa bioconversion results were significantly different (P<0.05) but the dry matter content, crude protein and NDF digestibility did not show significant differences (P>0.05) due to the levels of white oyster mushroom inoculum. The best digestibility occurred at the levels of white oyster mushroom inoculum 20g kg-1 substrate with acid digestibility fiber 27,31% and cellulose 31,08%. It can be concluded thah the level of white oyster mushroom inoculum 20g kg-1 substrate for nipah leaf midrib bioconversion results is the best.

The objective of this experiment was to determine the effects of feeding rabbits with Maxigrain® (M) enzyme supplemented Gliricidia sepium leaf meal (GLM) on their physiology, performance characteristics, and nutrients digestibility. Twenty weaned rabbits of mixed sexes, 5-6 weeks old, were randomly allotted to five dietary treatments including 0 g M which was soybean without M (control) and GLM supplemented with M at 50, 100, 150 and 200 g M per kilogramme of GLM. There were four rabbits per treatment and one rabbit as replicate in a completely randomized design. There were no significant (p > 0.05) treatment effects in all physiological and performance indices as well as those of crude fat, fibre and NFE digestibilities. There were variations (p < 0.05) due to the treatment effects on dry matter, crude protein and ash digestiblities. This implies that the feeding of soft faeces directly from the caecum called coprophagy mechanism in rabbits has its concomitant nutritional benefits. This advantageous benefit can enable rabbit to effectively and efficiently utilize forage or forage-based diet with or without enzyme supplementation.

The objective was to evaluate milk production, N2-fixation and N transfer, forage yield and composition (under two cutting intervals) in a silvopastoral system (SPS) with Leucaena leucocephala-Megathyrsus maximus and M. maximus-monoculture (MMM) with crossbred cows in a completely randomized design. Forage yield in the SPS was 6490 and 6907 kg DM ha−1 for cutting intervals (CI) of 35 and 50 days. Forage yield for the MMM was 7284 and 10,843 kg DM ha−1, and forage crude protein (CP) was 29.0% and 26.1% for L. leucocephala, harvested at 35 and 50 days, respectively. CP for the associated M. maximus was 9.9% and 7.8% for CI 35 and 50 days, respectively, and for MMM was 7.4% and 8.4%, harvested at 35 and 50 days. Milk production was 4.7 kg cow−1 day−1 for cows grazing MMM and 7.4 kg cow−1 day−1 under SPS. Nitrogen fixation in L. leucocephala (%Ndfa) was estimated to be 89% and 95%, at 35 and 50 days, with an N2 transfer to the associated grass of 34.3% and 52.9%. SPS has the potential to fix and transfer important amounts of N2 to the associated grass, and increase forage CP content and milk production.

This study aimed to assess the fermentation profile, losses and chemical composition of the silages of five sorghum cultivars. A completely randomized design with five replicates was used. The experimental treatments were represented by five sorghum cultivars (Sorghum bicolor (L). Moench): 'BRS Ponta Negra' , 'BRS 610', 'BRS 655', 'BRS 800' and 'BRS 810'. There was variation (P<0.05) for the pH in the cultivars studied, with highest result of pH by 'BRS 610'. The average percentages of lactic acid, acetic acid and propionic acid, differed (P<0.05) among the cultivars, ranging from 32.9 to 59.5, 19.8 to 39.8, and 0.0 to 1.3g kg-1, respectively. The dry matter recovery varied among cultivars (P<0.05), allowing the identification of BRS Ponta Negra, and 'BRS 810' silages, as those which recovered the lowest dry matter, with values of 757.1 and 776.1g kg-1, respectively. There were differences (P<0.05) for dry matter, crude protein, ether extract, neutral detergent fiber, non-fibrous carbohydrates and total carbohydrates contents among the cultivars. It was concluded that, despite the morphological and chemical differences among cultivars, the resulting silages had good fermentation profile.

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.

The objective of this study was to evaluate the crude protein content of Urochloa spp.cultivars (U. brizantha cv Marandu and U. decunbens cv. Basilisk), within a consortium systemwith Macrotyloma axillare cv Guatá. The experimental design was a completely randomized design,with four replications, in a factorial scheme (2 x 2), at which two types of grass (U. decumbensand U. brizantha) and two pasture types were studied (intercropped or exclusively fertilized with 60kg of nitrogen/ha) with repeated measures in time (samplings at two seasons of the year: February(summer) and August (winter)). Subsequently, samples were collected from a 2 m long PVC bar atfour points in each picket, and the forage cut close to the ground, with costal mowing coupled with0.5 m length hedge trimmer, each sample of 0.5 x 2.0 m, totalizing 1m2. The sampled material wasidentified, weighed and sent for analysis of crude protein to assess the contribution of leguminousin grass protein content. No significant differences were found when the type of grass versus type ofpasture interaction for the crude protein variable was met; however, significant differences were foundwhen evaluating the type of grass versus season interaction, at which the highest levels were foundwithin the month of February (summer), the same occurring for the interaction type of pasture versusseason of the year. It was concluded there were increases in crude protein content for U. decumbenscv. Basilisk and U. brizantha cv. Marandu when in consortium with M. axillare cv. Guatá in thesummer season.Keywords: Biological nitrogen. Forage. Forage quality. Leguminous.

The spring forage emptiness is an obstacle to the development of Brazilian livestock, including in the Bioma Pampa region. Feed strategies for this period contributed to the development of livestock and to the conservation of the biome. The objective of this work was to know the nutritional potential of forages during spring forage for use as strategies in the forage planning. The experiment had a completely randomized design, with ten forages and four replicates. The chemical composition, in vitro dry matter digestibility (IVDMD) and the total digestible nutrient content (NTD) of elephant grass, brachiaria cultivars Convert and Marandu, Tifton 68; diploid and tetraploid ryegrass; red, white and arrowleaf clover; and bird’s-foot trefoil. The grasses had a higher proportion of fibrous constituents, and lower levels of NDT and DMD, thus, lower nutritional value. Negative correlation between mineral matter and fibrous constituents with CP, TDN and IVDMD, was observed. Forages studied can be used as pasture alternatives for ruminants in the spring forage emptiness of the Pampa, Brazil, however, the strategy of using them should be a pasture planning.

Abstract This research aimed to reduce the lignin content and increase the nutrients content of sugarcane shoots as forages for a ruminant. This research used an experimental method using a completely randomized design (CRD) in factorial patterns, whereas A factor was a type of fungi (Pleurotus ostreatus and Aspergillus oryzae), and B factor was biodelignification time (14. 21 and 28 days). The variables observed in the experiment were laccase enzyme activity, Crude Protein (CP) content, and the percentage of lignin decreased. The research results showed that biodelignification using Pleurotus ostreatus fungi for 28 days resulted: 1,62 U/ml of laccase enzyme activity, 9.23% crude protein content, and 12.83 % of lignin decreased. From this research, the best treatment for bio-delignification of sugarcane shoots was with Pleurotus ostreatus fungi for 28 days, producing the best sugarcane shoots with 9.23 % of crude protein 12.83% of lignin decreased.
