    Objetivou-se com este trabalho avaliar o efeito da forma física do concentrado no desempenho e no desenvolvimento ruminal de bezerros leiteiros. Foram utilizados 22 bezerros Holandeses com peso corporal inicial médio de 43,2 kg, alojados individualmente e alimentados com dieta líquida (4 L/d) e concentrado inicial de duas formas físicas (peletizada ou farelada). O consumo de concentrado inicial foi monitorado diariamente e os animais pesados semanalmente, sempre após o fornecimento da dieta líquida, pela manhã. Após dez semanas, quatro bezerros de cada tratamento foram abatidos para coleta de amostras de fluido ruminal para determinação do pH e das concentrações de ácidos graxos de cadeia curta (AGCC) e de N-NH3 ruminal. Também foram realizadas medidas morfométricas do trato digestório superior. Não houve efeito da forma física no consumo de concentrado inicial, no peso corporal ou no ganho de peso diário dos animais. A forma física do concentrado inicial também não afetou o pH, as concentrações de AGCC ou de N-NH3 ruminal, assim como as medidas morfométricas do trato digestório superior, à exceção da capacidade do rúmen e do peso do abomaso, que foram maiores nos animais alimentados com concentrado peletizado. O fornecimento de concentrado farelado pode ser uma alternativa para a redução de custo de produção, uma vez que a forma física do concentrado não afeta o desempenho ou o desenvolvimento do trato digestório superior de bezerros leiteiros.The physical form of concentrate on the performance and rumen development on dairy calves was evaluated in this experiment. Twenty-two Holstein male calves, with 42.3 kg initial body weight, were individually housed, fed 4 L/d of liquid diet and starter concentrate in two physical forms (pelleted or coarsely ground). Starter concentrate intake was monitored daily and calves were weighted weekly, always after the morning liquid diet feeding. After 10 weeks, four calves from each treatment were slaughtered and rumen samples were taken for pH, rumen short chain fatty acids (SCFA) and N-NH3 concentration. Morphometric measurement of the forestomach was also evaluated. There was no effect of the physical form on starter concentrate intake, body weight, and daily gain. The physical form of the concentrate also had no effects on pH, SCFA or N-NH3 rumen concentration, nor on the morphometric measurements of the forestomach, except for rumen capacity and abomasum weight, which were higher for animals fed pelleted starter concentrate. Coarsely ground starter concentrate may be an alternative to reduced production costs since the physical form of the concentrate had no effect on performance or in the development of forestomach of dairy calves

    O objetivo neste trabalho foi avaliar o efeito da inclusão de butirato de sódio, monensina sódica ou propionato de cálcio no concentrado inicial sobre parâmetros ruminais e de desenvolvimento do trato digestório superior de bezerros leiteiros. Quinze bezerros holandeses recém-nascidos foram fistulados no rúmen e alojados em baias individuais até a décima semana de vida, com livre acesso a água, alimentados com leite (4 L/dia), em duas refeições, e concentrado à vontade contendo butirato de sódio (0,15%), monensina sódica (30 ppm) ou propionato de cálcio (0,15%). A partir da quarta semana de vida dos animais, antes e 2 horas após a alimentação da manhã, foram realizadas colheitas semanais de fluido ruminal para determinação do pH, da concentração de ácidos graxos de cadeia curta (AGCC) e N-amoniacal. Ao completar 10 semanas, os animais foram abatidos para avaliação do crescimento do trato digestório superior. O pH ruminal apresentou diferenças, tanto entre horários quanto entre os aditivos utilizados no concentrado inicial. As concentrações de AGCC totais, bem como de cada ácido graxo, não foram afetadas pelos aditivos. Entretanto, o horário de colheita teve efeito sobre todos os parâmetros, exceto a concentração molar de ácido acético. O peso total do trato digestório superior, assim como o peso médio de cada compartimento e a capacidade máxima do retículo-rúmen, não foram afetados pelos aditivos fornecidos no concentrado. Também não foram observados efeitos dos aditivos sobre a altura, a largura e o número de papilas do epitélio ruminal. A inclusão desses aditivos no concentrado inicial não afeta os parâmetros ruminais ou de desenvolvimento do trato digestório de bezerros em aleitamento.The objective of this study was the evaluation of the inclusion of calcium propionate, sodium butyrate and sodium monensin in the starter concentrate on ruminal parameters and forestomach development in dairy calves. Fifteen newborn Holstein calves were rumen cannulated and housed in individual stalls until ten weeks old, with free access to water, fed 4 liters of milk per day, split in two meals, and starter concentrate ad libitum containing sodium butyrate (0.15%), sodium monensin (30 ppm) or calcium propionate (0.15%). Starting at the fourth week of life, before and 2 hours after the morning feeding, ruminal fluid samples were taken weekly to determine the pH, short-chain fatty acids and ammonia-N. After 10 weeks, the animals were slaughtered to assess the forestomach growth. The rumen pH was affected by sampling time and the additives used in the starter concentrate. The total short-chain fatty acids concentration and each fatty acid concentration, were was not affected by the additives. However, except for molar concentration of acetic acid, all rumen fermentation parameters were affected by sampling time. The total forestomach weight and the average weight of each compartment and the maximum reticulum-rumen capacity were not affected by additives supplied in the starter concentrate. No significant effects of the additives were observed on the height, width and number of papillae of the ruminal epithelium. The inclusion of these additives in starter concentrate had no effect on most of the ruminal parameters and forestomach development in suckling calves.FAPES

    The objective of this study was to evaluate the route of administration of mannan-oligosaccharides in the diet of dairy calves and their effects on performance and plasma parameters indicative of rumen development. Following birth, twenty-four male Holstein calves were used in a completely randomized design and assigned to the following treatments: Control; 4 g/d Bio-Mos (R) (Alltech Biotech.) added to starter concentrate; and 4 g/d Bio-Mos (R) mixed into milk replacer. Animals were housed in individual hutches with free access to water, and fed 4L/d of milk replacer until weaning at six weeks. Calves also received 23g/kg crude protein of starter concentrate ad libitum. Fecal scores were evaluated daily. Body weights, growth measurements and blood samples for glucose, urea-N and beta-hidroxibutyrate analyses were taken weekly until 8 weeks of age. There were no significant effects of treatment or treatment x age interactions for mean starter concentrate intake, weight gain or body growth. However, there was a significant age effect for all parameters. Fecal scores were not affected by treatments. Also, plasma concentration of glucose, urea-N or beta-hidroxibutyrate were not affected by treatment or the treatment x age interaction. However, urea-N and beta-hidroxibutyrate concentrations significantly increased with age, suggesting adequate rumen development. Under the conditions of this study, there were no calf performance benefits when mannan-oligosaccharides were incorporated into milk replacer or calf starter concentrate.Fundacao de Amparo a Pesquisa do Estado de Sao Paulo (FAPESP)Fundacao de Amparo a Pesquisa do Estado de Sao Paulo (FAPESP)Conselho Nacional de Desenvolvimento Cientifico e Tecnologico (CNPq)Conselho Nacional de Desenvolvimento Cientifico e Tecnologico (CNPq

    Microabrasion in tooth enamel discoloration defects: three cases with long-term follow-ups

    Get PDF
    Superficial irregularities and certain intrinsic stains on the dental enamel surfaces can be resolved by enamel microabrasion, however, treatment for such defects need to be confined to the outermost regions of the enamel surface. Dental bleaching and resin-based composite repair are also often useful for certain situations for tooth color corrections. This article presented and discussed the indications and limitations of enamel microabrasion treatment. Three case reports treated by enamel microabrasion were also presented after 11, 20 and 23 years of follow-ups224347354sem informaçã

    O abastecimento de água potável é essencial para a manutenção da saúde e qualidade de vida. Em muitos países do globo, serviços de abastecimento de água de boa qualidade são comuns, porém, principalmente em países subdesenvolvidos, a situação é invertida. Nas zonas rurais, este cenário se deteriora, considerando a inviabilidade financeira e logística de se fornecer serviços dispendiosos a locais de difícil acesso e/ou isolados. Como forma de possibilitar o acesso a serviço de abastecimento de água potável nestas localidades, o modelo de gestão comunitária surge como uma alternativa promissora, porém com diversas falhas. A identificação destas falhas é fundamental para futuras intervenções e correções. A ferramenta SIASAR, criada por uma cooperação de países Latino-americanos, é responsável por identificar potenciais fragilidades em serviços de abastecimento de água rural. Neste artigo, esta ferramenta foi aplicada no serviço oferecido na comunidade de Mata Fria, Espírito Santo, Brasil. Embora aparente possuir um serviço sustentável, a ferramenta SIASAR possibilitou a identificação de fragilidades com potencial de gerar problemáticas no longo-prazo. Desta forma, possíveis intervenções futuras podem ser destinadas à solução de fragilidades específicas, evitando a aplicação de soluções generalizadas e pouco eficientes

    Guided Endodontics in Nonsurgical Retreatment of a Mandibular First Molar: A New Approach and Case Report

    Get PDF
    This case report describes the use of the guided endodontics for a non-surgical endodontic retreatment of the mandibular molar. A 38-year-old female reported apical swelling and localized pain on the tooth #30, exacerbated when chewing hard food. Periapical radiographic examination showed pulp canal obliteration in the apical third associated with extensive radiolucent area. Cone-beam computed tomography (CBCT) images were requested to support the diagnosis and enable preparation of a surgical guide, used to direct access to the canals that were obliterated and incompletely filled. The follow-up at 24 months radiographically showed completely healed apical area in the involved tooth. This non-surgical technique demonstrated efficacy in case resolution.Keywords: Cone-beam Computed Tomography; Endodontic; Guided Endodontic

    Evidence towards the involvement of nitric oxide in drought tolerance of sugarcane

    © 2017 Elsevier Masson SAS Exogenous supply of nitric oxide (NO) increases drought tolerance in sugarcane plants. However, little is known about the role of NO produced by plants under water deficit. The aim of this study was to test the hypothesis that drought-tolerance in sugarcane is associated with NO production and metabolism, with the more drought-tolerant genotype presenting higher NO accumulation in plant tissues. The sugarcane genotypes IACSP95-5000 (drought-tolerant) and IACSP97-7065 (drought-sensitive) were submitted to water deficit by adding polyethylene glycol (PEG-8000) in nutrient solution to reduce the osmotic potential to−0.4MPa. To evaluate short-time responses to water deficit, leaf and root samples were taken after 24h under water deficit. The drought-tolerant genotype presented higher root extracellular NO content, which was accompanied by higher root nitrate reductase (NR) activity as compared to the drought-sensitive genotype under water deficit. In addition, the drought-tolerant genotype had higher leaf intracellular NO content than the drought-sensitive one. IACSP95-5000 exhibited decreases in root S-nitrosoglutathione reductase (GSNOR) activity under water deficit, suggesting that S-nitrosoglutathione (GSNO) is less degraded and that the drought-tolerant genotype has a higher natural reservoir of NO than the drought-sensitive one. Those differences in intracellular and extracellular NO contents and enzymatic activities were associated with higher leaf hydration in the drought-tolerant genotype as compared to the sensitive one under water deficit

    The following is a clinical case report of a patient whose chief complaint was the presence of generalized spacing in the maxillary anterior segment following orthodontic treatment. After meticulous clinical analyses and discussions of the clinical procedures to be adopted, dental bleaching was performed in both arches with 10% hydrogen peroxide (Opalescence Trèswhite Supreme 10% Hydrogen Peroxide - Ultradent Products, Inc., South Jordan, USA) after the conclusion and stabilization of orthodontic treatment. Then, the orthodontic appliance was removed and the diastemas in the maxillary anterior teeth were closed with Amelogen Plus (Ultradent Products, Inc., South Jordan, USA) resin composite. It was observed that the association of orthodontic, bleaching, and restorative procedures was capable of restoring dental shape, function, and esthetics, allowing the patient to smile without hesitation
