Although tannin-rich forages are known to increase protein uptake and to reduce gastrointestinal nematode infections in grazing ruminants, most published research involves forages with condensed tannins (CT), while published literature lacks information on the anthelmintic capacity, nutritional benefits, and antioxidant capacity of alternative forages containing hydrolyzable tannins (HT). We evaluated the anthelmintic activity and the antioxidant capacity of plant extracts containing either mostly CT, mostly HT, or both CT and HT. Extracts were prepared with 70% acetone, lyophilized, redissolved to doses ranging from 1.0 mg/mL to 25 mg/mL, and tested against adult Caenorhabditis elegans as a test model. The extract concentrations that killed 50% (LC50) or 90% (LC90) of the nematodes in 24 h were determined and compared to the veterinary anthelmintic levamisole (8 mg/mL). Extracts were quantified for CT by the acid butanol assay, for HT (based on gallic acid and ellagic acid) by high-performance liquid chromatography (HPLC) and total phenolics, and for their antioxidant activity by the oxygen radical absorbance capacity (ORAC) assay. Extracts with mostly CT were Lespedeza cuneata, Salix X sepulcralis, and Robinia pseudoacacia. Extracts rich in HT were Acer rubrum, Rosa multiflora, and Quercus alba, while Rhus typhina had both HT and CT. The extracts with the lowest LC50 and LC90 concentrations, respectively, in the C. elegans assay were Q. alba (0.75 and 1.06 mg/mL), R. typhina collected in 2007 (0.65 and 2.74 mg/mL), A. rubrum (1.03 and 5.54 mg/mL), and R. multiflora (2.14 and 8.70 mg/mL). At the doses of 20 and 25 mg/mL, HT-rich, or both CT- and HT-rich, extracts were significantly more lethal to adult C. elegans than extracts containing only CT. All extracts were high in antioxidant capacity, with ORAC values ranging from 1800 moles to 4651 moles of trolox equivalents/g, but ORAC did not correlate with anthelmintic activity. The total phenolics test had a positive and highly significant (r = 0.826, p ≤ 0.01) correlation with total hydrolyzable tannins.

To evaluate the water requirements for Irrigated wheat, a mlcrometeorological study was conducted during the dry seasons of 1982 and 1983 at the Cerrados Agricultural Research Center, Brasilia-DF, BraziL The crop was Irrigated when the soU water potential at 5 cm reached-60 to -7OJIkg. Bowen ratio measurements were made on an hourly basls during the entire crop season, Total amount of water evapotranspired during the crop cycle and the energy balance terms varied year to year due to regional advection; ln 1982,a Iess advective year, the total amount of water evapotranspired was 345 mm, with approximately 80% of the net radlation dlsslpated as latent heat, 13% as a sensible heat and 7% as soU heat after the crop obtalned a Leaf Area lndex (LAI) of 1.5. ln 1983, when advection was greater than 1982, total water evapotranspired Increased to 385mm. The partitloning of energy was similar to 1982 during periods of title or no advecnon, However, during periods of Intense advection, latent heat was greater. In net radlation partitioning. Although regional advection Increased the water used by the crop, Irrigation scheduling based on soíl tensiometers was considered adequate and eflicient due to the low values of the Bowen ratio obtalned. Um estudo núcrometeorológico para avaliar a demanda hídrica do trigo Irrigado foi conduzido nasestações secas de 1982 e 1983 no Centro de Pesquisa Agricola dos Cerrados, Brasilia-DF, Brasil A cultura foi Irrigada quando o potencial de água no solo a 5 cm atinriu -60 a -70 JIkg. Durante todo o ciclo da cultura medidas da razão de Bowen foram feitas numa base horária. A quantidade total de água evapotranspirada durante todo ciclo da cultura e o balanço energético variaram entre os anos devido à advecção regional; em 1982, um ano menos advectivo, a quantidade total de água evapotranspirada foi de 345 mm, sendo 80% da radiação líquida dissipada como calor latente, 13% como calor sensível e 7% como calor do solo após a cultura ter atingido um Índice de Área Foliar (IAF) de 1.5. Em 1983, quando a advecção foi maior que em 1982, a quantidade total de água evapotranspirada aumentou para 385 mm. A partição de energia foi similar à 1982 durante periodos de pouca ou nenhuma advecção. Entretanto durante periodos de Intensa advecção, o calor latente representou a maior parte da radiação líquida. Apesar da advecção regional aumentar o consumo de água da cultura, programação da irrigação baseada em tensiometros foi considerada adequada e eficiente devido aos baixos valores da razão de Bowen obtidos.
