| The volatile oils extracted from the roots of Polygala extraaxillaris were analyzed to assess whether they increase oxidative stress in Brachiaria decumbens var. Piatã, as well as to assess their effect on cellular division and cytotoxicity in laboratory. Six concentrations were used (0%, 0.35%, 0.65%, 1.25%, 0.65%, and 5.0%) with four repetitions of 25 seeds. The substance 1-(2-hydroxyphenyl) - ethanone was identified as the major constituent of the volatile oils. The results showed that the highest concentrations of the oils resulted in an increase in the oxidative stress in B. decumbens, as well as alteration in germination and growth, with a consequent reduction in the process of cellular division, causing changes in the growth standard and antioxidant... |

| ABSTRACT In Brazil, some studies have indicated that Neorickettsia risticii circulates in horses, but it is unclear which are the possible intermediate vectors of this bacterium in the country. The aim of this study was to use molecular techniques in order to analyze the presence of N. risticii in snails and larval stages of trematodes in farms in a region with a history of seroreactive horses towards this bacterium, in Rio de Janeiro, Brazil. Convenience sampling was used in the studied region. The collected snails were exposed to incandescent light (60W) for 2-4 hours in order to investigate trematodes in larval forms. Deoxyribonucleic acid (DNA) was extracted from snail tissue and trematode. Real-time PCR (qPCR) technique was used to investigate the... |

| RESUMO Objetivou-se avaliar a viabilidade econômica de vacas F1 de Holandês x Zebu de diferentes bases maternas e ordens de parto. Foram utilizados dados do Campo Experimental da Epamig (Felixlândia-MG). Analisaram-se 406 lactações de vacas F1 H x Z de diferentes bases maternas. Estimaram-se a receita e os custos operacional efetivo, operacional total e custo total. As F1 Holandês x Gir tiveram médias de custos maiores (R$ 3582,30), seguidas pelas F1 Holandês x Nelogir (R$ 3448,06), e o menor foi das F1 Holandês x Nelore (R$ 3145,07). A receita total foi maior para as vacas F1 Holandês x Gir e F1 Holandês x Nelogir, com valores de R$ 4394,96 e R$ 4245,61, respectivamente, e a menor receita foi para F1 Holandês x Nelore, com valor de R$ 3976,12. O lucro foi... |
