Esse trabalho objetivou avaliar massa de forragem, densidade volumétrica e taxa de acúmulo de forragem, interceptação de luz e valor nutritivo de lâminas foliares do capim-xaraés submetido a intensidades de pastejo (15, 30 e 45 cm de altura) em lotação contínua com taxa de lotação variável. O delineamento experimental usado foi em blocos completos casualizados, com duas repetições. A massa de forragem total e a interceptação de luz dos pastos aumentaram com o incremento da altura de manejo,
apesar da taxa de acúmulo registrada para a altura de 30 cm não diferir das demais. A fibra em detergente neutro e a lignina em detergente ácido de lâminas foliares foram menores nos pastos manejados a 15 cm, enquanto que o teor de proteína bruta foi maior nos pastos mantidos a 15 cm. A produção de forragem mostra que o capim-xaraés apresenta boa flexibilidade de manejo, devendo ser manejado entre 30 e 45 cm de altura. |

Species of the Bromeliaceae are known for their pharmacological actions, including anthelmintic effects. The aim of this study was to investigate the in vitro anthelmintic activity of extracts and fractions of BRS Boyrá pineapple leaf against the eggs and infective larvae of gastrointestinal nematodes (Trichostrongylidae) of goats and to identify the compounds involved in this activity. Crude methanol, hexane, dichloromethane, ethyl acetate and residual hydromethanol extracts were investigated by quantitative analysis of phenolic and flavonoid contents, antioxidant activity, anthelmintic activity against gastrointestinal nematodes of goats. The extracts were submitted to chromatographic methods for substance isolation and spectrometric techniques to identify their structures. The anthelmintic activity was performed by in vitro assays with eggs and larvae of nematodes obtained from naturally infected donor goats. All extracts contained phenolic (2.22-14.12 g of gallic acid equivalent per 100 g of dry extract) and flavonoid compounds (0.13-1.45 g of quercetin equivalent per 100 g of dry extract). Bio-guided fractionation of the BRS Boyrá pineapple leaves showed high antioxidant activity (EC50 for DPPH of 2.16-21.38 mg mL-1 and inhibition of co-oxidation of B-carotene of 36.40-74.86%) and anthelmintic activity (15.69-100% inhibition of egg hatching). The ethyl acetate extract exhibited greatest activity in all assays. Through chromatographic column analysis it was possible to isolate three substances: B-sitosterol and stigmasterol mixture in dichloromethane and hexane extracts, identified by NMR and p-coumaric acid in the ethyl acetate extract, identified by HPLC-DAD. The isolated p-coumaric acid exhibited high ovicidal effect against goat gastrointestinal nematodes (IC50: 0.12 mg mL-1) and can be considered the active substance of the ethyl acetate extract. This study revealed for the first time that the pineapple BRS Boyrá possesses inhibitory activity against gastrointestinal nematodes (Haemonchus spp., Oesophagostomum spp. and Trichostrongylus spp.), and that p-coumaric acid is an important bioactive.
