Abstract: Sheep farming has shown expressive growth, even in the Northeast region of Brazil, with rainfall below expectations in the last decade. This growth has been observed not only in the number of herds, but also in the number of properties involved in sheep farming. Although expressive, the production of small ruminants still presents low levels of performance, mainly due to the occurrence of diseases, which constitute an obstacle to this activity. The aim of this study was to determine the factors associated with the seroprevalence of leptospirosis in sheep in Northeastern Brazil. Blood samples were collected from 3438 sheep in 190 herds from 48 municipalities, belonging to the states of Ceará, Paraíba, Piauí, Rio Grande do Norte and Sergipe. Serological diagnosis was performed using the microscopic agglutination test (MAT). In 76.3 % (95 % CI = 69.79?81.81) of the herds there was at least one animal seropositive for at least one of the Leptospira spp. serogroups and 14.94 % (95 %CI = 13.8?16.18) of the animals were seropositive. The state of Paraíba had the highest herd (95.7 %) and animal (26.6 %) prevalences, followed by Ceará (93.9 % and 23.7 %, respectively). The most frequent serogroups were Autumnalis (18.68 %), Australis (17.9 %) and Pyrogenes (15.18 %). There was no association between the studied variables and the herd-level prevalence of leptospirosis. High herd and animal-level seroprevalences was found for sheep leptospirosis in the semiarid region of Northeastern Brazil, and there is a need to implement control and prevention measures, such as quarantine, serology, vaccination and adequate treatment, in addition to the introduction of proven healthy animals, mainly in the states of Paraíba and Ceará, aiming to reduce the prevalence of disease.

Em Piracicaba,SP, durante o periodo de inverno e em terra roxa estruturada latossolica, o acumulo de materia seca e de N no milho foi analisado em funcao da aplicacao de 120 kg/ha de N, na forma de ureia-amonio-nitrato (URAN) no solo, aos 13 e 47 dias apos a emergencia das plantulas (dae), com doses de 40 e 80 kg/ha de N, respectivamente, e via agua de irrigacao (fertirrigacao), aos 34, 49, 64, 82 e 101 dae, na doses de 4, 6, 45, 30 e 35 kg/ha de N, respectivamente. Observou-se que as plantas fertirrigadas apresentaram maior diferenciacao aos 95 dae, com maior teor de N na materia seca e, consequentemente, a quantidade de N permaneceu maior ate a colheita (150 dae). As aplicacoes de N em estadios mais avancados do desenvolvimento do milho proporcionaram maior acumjlo de materia seca e de N na parte aerea, maior translocacao de N na parte aerea, maior translocacao de N para os graos e maior producao de graos (5.072 kg/ha), nas plantas fertirrigadas, em comparacao com as plantas fertilizadas no solo (4.516 kg/ha). |
