“…Legumes from Caatinga synthesize a great amount of insoluble protein, which adheres to the fiber (Santana et al 2011), lignin and condensed tannins (Beelen et al 2006a;Oliveira et al 2015), affecting nutrient digestibility (Beelen et al 2006b;Silva et al 2012). Most forages in the northeastern semi-arid region can synthesize anti-nutritional factors, such as tannins and lignins, from the secondary metabolism of plants, which can bind to protein and other nutrients, negatively influencing animal performance (Beelen et al 2006b;Pereira et al 2010). Furthermore, forage legume management can influence the accumulation of those compounds, as grazed plants can have more condensed tannins than ungrazed ones (Adams et al 2013).…”

Short CommunicationChemical composition of hays of the Caatinga shrub legumes mororó and sabiá from different parts of the plant . The findings suggest that these native legumes can be conserved as hay during the growing season to provide a supplementary feed with acceptable nutritive value for feeding during the period of inadequate feed availability and quality in semi-arid Brazil. However, more samples from a range of growth stages and locations are needed to confirm these preliminary findings and to provide data on possible yields, while more feeding studies with ruminants are needed to confirm the preliminary data in terms of liveweight performance.Keywords: Bauhinia cheilantha, Mimosa caesalpiniifolia, native forages, non-fiber carbohydrates, plant fractions. ResumenEn la región semiárida del nordeste de Brasil, las plantas nativas son una fuente importante de forraje. El objetivo de este estudio fue evaluar las características químicas de los henos de las leguminosas arbustivas nativas: sabiá (Mimosa caesalpiniifolia Benth.) y mororó [Bauhinia cheilantha (Bong.) Steud.], utilizando diferentes fracciones de las plantas: solo hojas y hojas más ramificaciones delgadas (<8 mm diámetro) de tallos. Los análisis incluyeron: concentraciones de materia seca (MS), proteína cruda (PC), fibra detergente neutra (FDN), extracto de éter (EE), ceniza, nutrientes digestibles totales (NDT) y carbohidratos no fibrosos (CNF). El heno de hojas de sabiá presentó mayor concentración de PC (182 g/kg de MS) que el heno de hojas de mororó (126 g/kg de MS); no obstante en ambas leguminosas las concentraciones de PC fueron similares cuando se analizaron hojas más ramificaciones de tallos (106 g/kg de MS en promedio). Las concentraciones de FDN (368 g/kg de MS), CNF (418 g/kg de MS) y NDT (481 g/kg de MS) del heno de hojas de mororó fueron superiores a las del heno de hojas de sabiá (465, 258 y 311 g/kg de MS, respectivamente). Los resultados sugieren que en la región semiárida de Brasil estas leguminosas nativas, conservadas como heno durante

“…Crude protein concentration of forage can be misleading as an indicator of the feed value as part of the nitrogen in hay may be fiber-bound in some native plants (Santos et al 2010;Silva et al 2012).

“…Tannins act directly against cellular organelles and within the cell membranes of various microorganisms, inhibiting their growth (MIN et al, 2008;RODRIGUES et al, 2014;AGOSTINI-COSTA et al, 2015). Recent studies indicate that tannins present great potential in binding proteins and adhesins, interfering directly in the substrate availability necessary for bacterial metabolism and growth (JONES et al, 1994;HASLAM, 1996;GUIMARÃES-BEELEN et al, 2006;RODRIGUES et al, 2014).…”

Effects of associations of tannins from Anacardium occidentale and Anadenanthera colubrina with cephalosporin against bovine Staphylococcus aureus isolates

The association of natural compounds isolated from medicinal plants with conventional antibiotics, both with similar mechanisms of action, have become a viable alternative strategy to overcome the problem of drug resistance. This study aimed to evaluate the in vitro antimicrobial activity of tannic substances present in the bark of Anacardium occidentale and Anadenanthera colubrina against samples of Staphylococcus aureus when in combination with cephalexin. These combinations were evaluated by determining the minimum inhibitory concentration (MIC). For this purpose, tannins and cephalexin were serially dissolved in distilled water at concentrations ranging from 0.976 mg/mL to 500 mg/mL and 2 mg/mL to 512 mg/mL, respectively. When combined, the compounds inhibited S. aureus growth forming halos ranging from 0.9 to 46 mm with an MIC of 7.8 mg/mL (tannins) and 4 µg/mL (cephalexin). The resulting effect of the combination of natural and synthetic substances with similar mechanisms of action presented better results than when tested alone. Thus, the conclusion is that both the tannins and cephalexin had their antimicrobial action enhanced when used in combination, enabling the use of lower concentrations while maintaining their antibacterial effect against strains of S. aureus.
