“…Segundo Silva et al (2016), na MS das forragens é onde estão os principais nutrientes como carboidratos, proteínas e lipídeos a serem metabolizados e absorvidos. Quanto a queda nos percentuais desses nutrientes no decorrer dos períodos de armazenamento, possivelmente, está relacionada ao processo fermentativo, respiração celular e metabolismo dos agentes anaeróbios durante a produção da silagem (Andrade et al, 2012 Bonfá et al (2015) trabalhando com silagem de capim elefante adicionada de casca de maracujá observaram valores maiores (5,3%), porém ainda abaixo dos considerados limitantes, que devem estar entre 6% e 7%. Esses teores são considerados aceitáveis em forrageiras tropicais, pois Development, v. 9, n. 9, e644997789, 2020 (CC BY 4.0) | ISSN 2525-3409 | DOI: http://dx.doi.org/10.33448/rsd-v9i9.7789 geralmente, essas plantas possuem concentrações baixas quando confrontadas com certos alimentos concentrados, pois podem abranger gorduras, óleos voláteis, resina e clorofila (Costa et al, 2019).…”

Objetivou-se avaliar a composição bromatológica e perfil fermentativo da silagem com 20% de capim elefante e 80% de torta de cupuaçu com diferentes tempos de armazenamentos. O experimento foi realizado no setor de Bromatologia da Universidade Federal do Acre (UFAC), Rio Branco-Acre, em delineamento inteiramente casualizado (DIC), com cinco tratamentos e quatro repetições (T1=7 dias; T2= 14 dias; T3= 21 dias; T4= 28 dias e T5= 35 dias). Foram utilizados 20 silos experimentais de policloreto de vinila (PVC) com capacidade de 2 kg e avaliados potencial hidrogeniônico (pH), matéria seca (MS), proteína bruta (PB), material mineral (MM), extrato etéreo (EE), fibra em detergente ácido (FDA), fibra em detergente neutro (FDN), hemicelulose (HEM), lignina (LIG), perdas de matéria seca (PMS), gases (PG) e efluentes (PE). Os dados foram submetidos à análise de variância e médias comparadas pelo teste Tukey (P<0,05), utilizando-se o programa estatístico SISVAR, versão 2012. Os resultados referentes ao potencial hidrogeniônico (pH) diferiram estatisticamente (P< 0,05). MS, PB, MM, EE, e NDT apresentaram diferenças significativas (P<0,05) entre os tratamentos, com destaque para 35 dias de armazenamento, o qual apresentou melhor teor de FDA, HEM e LIG. Os níveis de HEM, perdas por gases (PG) e efluentes (PE) diferiram estatisticamente (P<0,05). Conclui-se que silagens de capim elefante com torta de cupuaçu na proporção estudada apresentaram composição bromatológica com perdas de matéria seca, efluentes e gases em níveis aceitáveis quando o período de armazenamento é superior a 28 dias.

“…However, when passion fruit seed was used in the diet of laying hens, there was no difference in egg production and feed conversion, but the specific gravity of eggs increased with the concentration of seeds, while total cholesterol and blood triglycerides decreased linearly, and also a decrease in the yolk lipid oxidation was evidenced (Zanetti et al., ). The addition of passion fruit byproducts in elephants silage (Bonfá et al., ; Cardoso de Azevedo et al., ) increased the dry matter and favored the fermentative, microbiological, and bromatological silage processes, while in pig feeding, seed meal showed to increase the serum levels of cholesterol (Perondi et al., ). Similarly, the mixture between grass and passion fruit peel could be an efficient and environmental acceptable way to preserve feeds in order to sustain the productivity of the herds during the dry season (Espinoza et al., ).…”

Tropical fruits represent one of the most important crops in the world. The continuously growing global market for the main tropical fruits is currently estimated at 84 million tons, of which approximately half is lost or wasted throughout the whole processing chain. Developing novel processes for the conversion of these byproducts into value‐added products could provide a viable way to manage this waste problem, aiming at the same time to create a sustainable economic growth within a bio‐economy perspective. Given the ever‐increasing concern about sustainability, complete valorization through a bio‐refinery approach, that is, zero waste concept, as well as the use of green techniques is therefore of utmost importance. This paper aims to report the status on the valorization of tropical fruit byproducts within a bio‐refinery frame, via the application of traditional methodologies, and with specific attention to the extraction of phenolics and carotenoids as bioactive compounds. The different types of byproducts, and their content of bioactives is reviewed, with a special emphasis on the lesser‐known tropical fruits. Moreover, the bioactivity of the different types of extracts and their possible application as a resource for different sectors (food, pharmaceutical, and environmental sciences) is discussed. Consequently, this review presents the concepts of tropical fruit biorefineries, and the potential applications of the isolated fractions.

“…However, in recent years, there has been growing interest in the use of forage grasses for silage production. The ensiling of these grasses has some advantages: high forage production, better use of the cultivated areas of the property, with a reduction in the areas destined to crops; in addition to lower forage losses in the dry period of the year (Bonfá et al, 2015).…”

The aim of this study was to evaluate nutritional value, fermentation losses, and aerobic stability of elephant grass silage (Pennisetum purpureum Schum.) treated with exogenous fibrolytic enzymes. The experiment was conducted in a completely randomized design with four replicates (experimental silos) and five levels of fibrolytic enzymes (0, 1.5, 3.0, 4.5 and 6.0%). For this, the elephant grass was ensiled at 70 days of age in plastic buckets with 20L capacity. Silos were opened 60 days after sealing. Analyses were made for chemical composition, in vitro dry matter digestibility (IVDMD), effluent losses (EL), gas losses (GL) and dry matter recovery (DMR), as well as the aerobic stability of the silage. Data were analyzed with PROC REG of SAS® University, at 5% probability. There was an increase in IVDMD content (p < 0.0001) and reduction in NDF and ADF contents (p < 0.0001) according to enzyme levels. These results were related to the increase in the degradation of fiber fractions. There were higher EL (p = 0.0062) as a function of enzyme levels and aerobic deterioration after silo opening, at all levels tested. Thus, it can be concluded that the exogenous fibrolytic enzymes change the chemical composition of elephant grass silage, and increase its digestibility and nutritional value. Moreover, when used alone as an additive, fibrolytic enzymes are not able to recover all dry matter of this silage (with effluent and gas losses), and are not able to maintain aerobic stability in the first hours after opening the silos.
