| Building of leaf shelters is a widespread behavior among microlepidopteran larvae. Apparently, these shelters provide refuge to caterpillars against bad weather and reduce the risks of predation and parasitism. Recent studies about nutritional ecology of insects have suggested that such behavior would actually be an strategy evolutionarily selected to maximize the quality of the host plant consumed by them. Stenoma scitiorella Walker caterpillars tie together young Xylopia aromatica (Lam.) Mart. (Annonaceae) leaves to build a shelter in which they retreat, feeding exclusively on inner leaves. The accumulation of damage and excrement in leaf shelters with several caterpillars may lead to a decline in larval development and survivorship. For providing the... |

| A espécie medicinal Maytenus ilicifolia (Mart. ex Reiss.) localiza-se naturalmente sob diferentes condições edafoclimáticas. Isto implica em prováveis mecanismos de adaptação das populações naturais, cujas características químicas podem estar fixadas geneticamente. Este estudo foi desenvolvido para determinar a influência do ambiente sobre a composição fitoquímica de M. ilicifolia. Amostras de plantas foram coletadas em quatro populações naturais localizadas sobre diferentes superfícies geológicas no Estado do Paraná e sob distintas condições de luminosidade (pleno sol, meia sombra e sombra). Os solos foram classificados segundo o Sistema Brasileiro de Classificação. Foram avaliados os teores foliares de N, P, K, Ca, Mg, Fe, Mn, Cu, Zn, Si, Al, lignina,... |

| The traditional method of total excreta collection was applied, using 30 to 40 day old male Ross 308 broiler chickens. One hundred and eight broiler chickens were used, randomly assigned to a 3x3 factorial experimental design. The room temperatures were 14 C (cold), 25 °C (thermoneutral) and 32 °C (hot) and the three diets were 100% maize, 100% sorghum with tannin and 100% sorghum without tannin, with four replicates of each. The digestibility coefficients for the dry matter, crude protein, crude fibre, neutral detergent fibre, acid detergent fibre, ether extract, mineral matter and nitrogen-free extract were determined. It was observed that all the digestibility coefficients were higher in the hot chamber and lower in the cold chamber, and that these... |

| The objective of this work was to study the effect of caffeine and tannins on Pleurotus sp. cultivation and to evaluate the feasibility of using coffee husks as substrate for mushroom cultivation. Eight strains of P. ostreatus and two strains of P. sajor-caju were screened on a medium prepared from agar extract of coffee husk. Based on best mycelial growth and biomass production, the strain P. ostreatus LPB 09 was selected for detailed studies. With the increase of caffeine concentration, the mycelial growth and the biomass production decreased, and no growth was observed when concentration of caffeine was 2500 mg/L. Furthermore, Pleurotus did not degrade the caffeine, but absorbed it. Tannin under 100 mg/L in the medium stimulated the growth of mycelia,... |

| In the present study, the effectiveness of Mimosa pudica tannins (MPT) in neutralizing the lethality of Naja kaouthia venom was compared with commercially derived tannins. Preincubation of MPT with N. kaouthia venom maintained 100% survival of mice after 24 hours. The mouse group in which there was no preincubation, no protection against the effects of the venom was observed. M. pudica tannin was found to be more effective in neutralizing the lethality of N. kaouthia venom when compared to commercial tannic acid. Two protein spots were missing in the two-dimensional gel electrophoresis (2-DE) of the MPT treated mouse indicating the down-regulation of venom proteins. The results from this study indicated that tannins obtained from M. pudica are better than... |

| Este estudo teve como objetivo determinar as atividades dos inibidores de tripsina, hemaglutinante e teores de taninos no farelo de soja e na soja crua e processada, e avaliar o coeficiente de digestibilidade aparente da fração proteica para juvenis de pacu. Os coeficientes de digestibilidade aparente da proteína da soja crua, extrusada, tostada e macerada foram determinadas usando óxido de cromo (0,5%) como marcador. Foi elaborada dieta de referência com 26% de proteína bruta e 4.352 kcal kg-1, e a cada alimento avaliado foram substituídas 30% da dieta-teste. As fezes foram coletadas por pressão abdominal. Todos os produtos analisados apresentaram fatores antinutricionais, mas foi observada menor atividade de inibidor de tripsina no farelo de soja. Sojas... |

| This experiment was carried out to evaluate the effects of replacing corn by high tannin sorghum in diets of japanese quails (Coturnix coturnix japonica) on performance and egg quality. Two hundred and fifty-two quails with 50 weeks of age were evaluated during four periods of 21 days. The treatments consisted of diets containing 20, 40, 60, 80 and 100% of sorghum, and a control treatment (100% of corn). Diets were formulated so that the levels of energy, protein, amino acids (methionine+cystine and lysine), calcium and phosphorus were similar A completely randomized experimental design was used, with six treatments, six replicates and seven quails for experimental unit. Evaluated parameters were egg production (%), feed intake, feed: gain ratio (kg/kg and... |

| This study aimed to evaluate in situ degradability and degradation kinetics of DM, NDF and ADF of silage, with or without tannin in the grains. Two isogenic lines of grain sorghum (CMS-XS 114 with tannin and CMS-XS 165 without tannin) and two sorghum hybrids (BR-700 dual purpose with tannin and BR-601 forage without tannin) were ensiled; dried and ground silage samples were placed in nylon bags and introduced through the fistulas. After incubation for 6, 12, 24, 48, 72 and 96 hours, bags were taken for subsequent analysis of fibrous fractions. The experimental design was completely randomized with 4 replicates and 4 treatments and means compared by Tukey’s test at 5% probability. As for the DM degradation rate, silage of CMSXS165without tannin was... |

| The nutritional value of browse foliage from the Thorny Kalahari Dune Bush veld of South Africa is not characterized. Most of this browse species is rich in tannin, but still palatable, and is consumed by ruminants during the dry season, as well as having a role to play in mitigating enteric methane emission from ruminants. In this study, the rumen methane mitigation potential of 19 browse species foliage collected from the Thorny Kalahari Dune Bush veld, was analyzed in terms of chemical composition, in vitro fermentation, digestibility and methane production. In vitro gas and methane production and organic matter digestibility (IVOMD) were determined by using rumen fluid collected, strained and anaerobically prepared. A semi-automated system was used to... |

| ABSTRACT Anisophyllea laurina is a plant that has been used in folk medicine to treat malaria, dysentery, diabetes, toothache and various skin diseases. Leaves extract had protein content of 9.68% and a high calcium content of 25084.317 mg/100 g while stem bark extract was found to contain greater amounts of calcium (8560.96 mg/100 g), potassium (7649.47 mg/100 g), magnesium (1462.49 mg/100 g) and iron (973.33 mg/100 g). Palmitic acid, linolenic acid, linoleic acid and oleic acid were the most abundant fatty acids in leaves and stem bark extracts. Furthermore, total phenolic (2382.39 mg GAE /100 g) and total flavonoid (385.79 mg QE/100 g) contents were abundant in stem bark while leaves extract was rich in total tannin content (3466.63 mg CE/100 g).... |
