RESUMO:O objetivo do presente trabalho é descrever os principais aspectos epidemiológicos, clínico-patológicos e radiológicos de malformações em pequenos ruminantes no semiárido do estado da Bahia. Foram realizadas visitas técnicas em 41 propriedades rurais no município de Uauá, Bahia, e em cada uma delas foi aplicado um questionário epidemiológico. Adicionalmente, quando se observavam casos de malformações, os animais eram avaliados vivos ou mortos. Foram necropsiados oito animais (1, 2, 3, 4, 5, 6, 7 e 8), e dois (7 e 8) foram submetidos a exame radiográfico. Sobre a alimentação do rebanho, 40 (97,56%) produtores rurais relataram o livre acesso de seus animais à vegetação nativa. Em relação à presença de Mimosa tenuiflora, 5 (12,2%) informaram que os animais tinham acesso à planta, 15 (36,6 %) disseram que tinham pouco contato, enquanto que 21 (51,2 %) relataram que não havia nenhum contato com a planta, pois essa espécie não estava presente em número relevante na região. Vinte e cinco dos 41 proprietários (60,98%) relataram o consumo de Poincianella pyramidalis. Foi constatado ainda que na maioria das propriedades havia muitas áreas invadidas por P. pyramidalis (80-90% da vegetação). As principais anormalidades relatadas pelos entrevistados em 36 propriedades foram artrogripose (87,80%), agnatia [22 (53,66%)], desvio lateral da mandíbula [11 (26,82%)], escoliose [6 (14,63%)], micrognatia [6 (14,63%)], fenda palatina [4 (9,75%)], crânio aumentado de tamanho [4 (9,75%)], microftalmia [2 (4,88%)], braquignatismo [1 (2,43%)], exoftalmia [1 (2,43%)] e deformidades múltiplas no crânio [1 (2,43%)]. No exame clínico de 13 animais com malformações, as principais alterações foram artrogripose bilateral dos membros torácicos (6/13); queilosquise (2/13); micrognatia (1/13) e má oclusão dentária (1/13). Considerando que algumas dessas malformações foram reproduzidas experimentalmente em caprinos pode-se sugerir P. pyramidalis como mais uma planta teratogênica para ruminantes no Nordeste do Brasil.
ABSTRACT: The aim of this paper is to describe the epidemiological, clinical-pathological and radiological aspects of malformations in small ruminants in the semi-arid state of Bahia. Technical visits were carried out in 41 rural properties in the city of Uauá, Bahia, and in each of them, an epidemiological questionnaire was applied. In addition, when malformations were observed, the animals were evaluated alive or dead. Eight animals (1, 2, 3, 4, 5, 6, 7 and 8) were necropsied, and two (7 and 8) were submitted to radiographic examination. Regarding the feeding of the herd, 40 (97.56%) farmers reported the free access of their animals to the native vegetation. Regarding the presence of Mimosa tenuiflora, 5 (12.2%) said that the animals had access to the plant, 15 (36.6%) was informed they had little contact, while 21 (51.2%) reported that there was no contact with the plant, because this species were not present in a relevant number in the region. Twenty five out of 41 owners (60.98%) reported the consumption of Poincianella pyramidalis. It was also verified that in the majority of the properties there were many areas invaded by P. pyramidalis (80-90% of the vegetation). The main abnormalities reported by the interviewees on 36 properties were arthrogryposis (87.80%), agnatia [22 (53.66%)], lateral deviation of the mandible [11 (26.82%)], scoliosis [6 (14.63%)], micrognathia [6 (14.63%)], cleft palate [4 (9.75%)], skull enlarged in size [4 (9.75%)], microphthalmia [2 (4.88%)], braquignatism [1 (2.43%)], exophthalmia [1 (2.43%)] and, multiple deformities in the skull [1 (2.43%)]. In the clinical examination of 13 animals with malformations, the main alterations were bilateral arthrogryposis of the thoracic limbs (6/13); cleft lip (2/13); micrognathia (1/13) and dental malocclusion (1/13). Considering that some of these malformations were reproduced experimentally in goats, it is possible to suggest P. pyramidalis as another teratogenic plant for ruminants in Northeast Brazil.

ABSTRACT.
Knowledge of soil potassium (K) dynamics and quantification of plant-available K reserves are essential for the correct management of this nutrient. The objectives of this study, conducted in six Uruguayan mollisols, were to (i) determine the contribution of plant-available nonexchangeable K to plant nutrition, (ii) compare the ability of the ammonium acetate (NH4OAc) method and the sodium tetraphenylboron (NaBPh4) method to determine plant-available K, and (iii) quantify the effect of K fixation and release processes on the ability of both methods to estimate changes in K availability due to different K balances. In a greenhouse experiment, perennial ryegrass (Lolium perenne, cv. Horizon) was grown over a period of 320 days in six soils fertilized with 0, 100, 200, and 400 mg K kg?1. We measured plant K uptake and the changes in soil K status related to different K balances using NH4OAc and NaBPh4. Use of NaBPh4 resulted in a more accurate determination of plant-available K (R2 = 0.97 vs. 0.78) and soil K balance (R2 = 0.73 vs. 0.63), but neither of the methods was suitable for identifying positive K balances. However, when positive balances were established by K addition and incubation without plant growth, both methods related well with K balances. Again, NaBPh4 was better than NH4OAc (R2 = 0.98 and 0.88, respectively). The more accurate determination of plant K uptake and the strongest relationship with K balance of NaBPh4 was due to the extraction of exchangeable K plus a proportion of plant-available nonexchangeable K. Soil?plant interactions enhance soil K fixation in forms that are available to plant absorption but are not extractable by the chemical methods considered in this study.
