Published: December 2019

ABSTRACT Objective: to understand the perceptions and expectations of pregnant women about the type of birth. Method: this is a qualitative research, based on the assumptions of the Humanization of Obstetric Care. 15 pregnant women were interviewed twice at the beginning and the end of gestation between October 2015 and May 2016. Data were analyzed according to the method of the Discourse of the Collective Subject. Results: the discourses were associated with four themes: Advantages of vaginal birth over cesarean section; Fear and unpredictability of vaginal birth; Importance of the doctor in the definition of the type of birth; and Influence of family and friends in choosing the type of birth. Final considerations: according to pregnant women, vaginal birth has more benefit compared to cesarean section. However, during gestation and birth, fear of pain and the unexpected, and medical opinions of friends and family against vaginal birth strongly influence the choice of cesarean section.

Published: December 2019

ABSTRACT Objective: to describe the health behaviors related to the sexual experiences of women in the female prison system from January to March, 2017. Method: descriptive study with a qualitative approach. A semi-structured questionnaire containing mixed questions and patient records was used. The data analysis was performed through the Bardin’s content analysis and adopted as reference the Theory of Basic Human Needs. Results: 18 women, young, single, brown, with a complete fundamental level participated in the study. After this characterization, two categories were evidenced: Health behaviors in sexual experiences and Health care in the face of sexual experiences. 33.3% reported on health behaviors such as Sexually Transmitted Infections (STIs), 27.7% associated with male condom use, 16.6% on prevention of unwanted pregnancies, 11.1% on health care and hygiene. Final considerations: it was evidenced that the health behaviors reported by women in sexual experiences are associated with actions to prevent STIs, use of condoms, unwanted pregnancies, and health and hygiene care. However, it is possible to infer that they understand and possess superficial knowledge about health behaviors and that there is no adoption of regular practice in their sexual experiences.

Published: December 2019

ABSTRACT Objective: To comprehensively analyze the perception of women with breast cancer on the experience of undergoing chemotherapy. Method: This was a qualitative, descriptive, phenomenological study, supported by the Merleau-Ponty philosophy. It was conducted in a chemotherapy outpatient clinic with 20 participants who completed a phenomenological interview. Results: The phenomenological data analysis demonstrated that the perception of women about the experience of chemotherapy is about change, not only of the physical body, but of their identity, and that it considers existential aspects. Three categories emerged from the experience of alopecia, fatigue, and spirituality, respectively: the body itself, the current and habitual body, and transcendence. Final considerations: Bodily changes, and the existential implications perceived by the women in this study, analyzed from the Merleau-Ponty perspective, makes it possible to consider body concept, and provides support for humanized care based on singularity and the socio-cultural context.

Published: December 2019

ABSTRACT Objective: To identify maternal dilemmas about the diagnosis of fetal abnormality incompatible with life. Method: The exploratory-descriptive qualitative method was used. Eight women participated in the research between September/2016 and January/2017 through semi-structured interviews. The data were analyzed from the thematic analysis together with the ATLAS.ti software. Results: The experiences of this study were based on suffering and emotions. The termination choice was based on personal factors of women and families, such as information on pathology and religion. Diagnoses of incompatible fetal abnormalities bring the most different feelings to those involved. It is extremely important to establish a clear communication between woman, family and interdisciplinary team in the course of gestation and delivery, with elucidation about prognosis and therapeutic possibilities. Final considerations: It was visualized the importance of embracement, communication and treatment given by the multiprofessional health team.

ABSTRACT Objective: To know the maternal perception about early stimulation and its repercussion in the development of the child with microcephaly associated with zika virus. Method: A qualitative study was carried out from June to August 2017 with five mothers of children diagnosed with microcephaly associated with zika virus. The data were collected through individual interviews with semi-structured script and evaluated by the content analysis, in its thematic modality. Results: Mothers recognized the benefits and the advances in the development of the child after the beginning of the early stimulation. It is noteworthy that the difficulty of transportation was the main reason for the lack of attendance at consultations, and that the short time of stimulation was the main weakness of the service. Final considerations: The recognition of maternal perception and the difficulties and weaknesses of the service can contribute to the elaboration of public policies and the planning of holistic care for children with microcephaly and their families.

Authors: Vigato Estefanie Siqueira , Lamas José Luiz Tatagiba
Published: December 2019

ABSTRACT Objective: to compare blood pressure values obtained by auscultatory and oscillometric methods in different gestational periods, considering cuff width. Method: it is a cross-sectional and quasi-experimental study approved by the Research Ethics Committee. The sample consisted of 108 low-risk pregnant women. Blood pressure measurements were performed in gestational periods of 10-14, 19-22 and 27-30 weeks. Results: The oscillometric device presented values similar to the auscultatory method in systolic blood pressure, but overestimated diastolic blood pressure. Underestimation of blood pressure occurred when using the standard width cuff rather than the correct width cuff in both measuring methods. Conclusion: Verification of brachial circumference and use of adequate cuffs in both methods are indispensable to obtain reliable blood pressure values in pregnant women. We recommend performance of additional studies to evaluate diastolic blood pressure overestimation by the Microlife 3BTO-A.

Published: December 2019

ABSTRACT Objective: To assess the effectiveness of remote monitoring in the knowledge of overweight women. Method: Randomized clinical trial with 101 women, randomly assigned to the control group (CG=50) and to the intervention group (IG=51). The IG received educational intervention over the telephone, during three months and routine follow-up in the service, while the CG only received conventional follow-up. The knowledge was assessed by a specific questionnaire. Data were analyzed by the Robust Linear Regression Model, adopting a statistical significance of 5%. Results: In the intragroup assessment, an increase in the correct answers with a statistically significant difference was observed only for the IG in the domains: “Concept and causes of overweight,” “Complications of overweight” and “Eating habits.” In the intergroup comparison, an increase in the average knowledge was verified in the same domains for the IG (p≤0.005). Conclusion: nursing telemonitoring contributed positively to the improvement of women’s knowledge.

Published: December 2019

ABSTRACT Objective: to know the social and family relationships of pregnant women and to analyze their influence in keep smoking during pregnancy. Method: it is a descriptive-exploratory study with a qualitative approach, which had as subjects 10 pregnant smokers. Data were collected from January to March / 2015, through interviews, and organized into graphical representations of the genogram/ecomap and discourse units. Results: pregnant women had low educational level, precarious insertion in the work market and relations of great dependence of the family. Tobacco consumption integrates the family environment and is viewed naturally in the sociocultural environment. In prenatal care, there was no coordinated and longitudinal intervention for smoking cessation. Conclusion: smoking cessation is strongly influenced by the social environment, and the family is an important component of this network. In this sense, strategies to approach smoking should allow a reflection of the norms and rules of the family.

Published: December 2019

Abstract Concretes present great potential to be used in many areas of civil construction. Their properties can be improved by substitution or addition of alternative materials to the Portland cement. The diatomite is a sedimentary material composed mainly by silica and amorphous impurities, presenting very fine particle size, high porosity, and low specific mass. Concrete was produced in a ratio of 1:1:2 (cement: sand: gravel) with the addition of diatomite at contents of 5% and 10% by cement weight and a water/cement ratio of 0.54. The physico-mechanical properties of the concretes were evaluated by tests of compressive strength and water absorption by immersion. Also, X-ray diffraction and scanning electron microscopy were carried out to analyze the main phases in the cement paste. The results indicated that the addition of diatomite in the concrete increased the compressive strength due to the silica content in the material and reduced slightly the porosity.

Authors: Pagano E. , Chinelatto A. S. A. , Chinelatto A. L.
Published: December 2019

Abstract Alumina ceramic materials with graded functional porosity were prepared by the freeze casting method and characterized. The effects of processing route parameters on the pore formation were studied. Pore characteristics were investigated concerning morphology and distribution in the ceramic matrix. The mercury intrusion method was used to evaluate the porosity. Mechanical properties, as well as the fracture mode, were investigated by the uniaxial compression test. Scanning electron microscopy was used to analyze and correlate the created interface between the layers with the mechanical response. The results suggested that the porosity obtained in all samples was similar, even with varying parameters (different suspension solidification configurations). When evaluating the mechanical behavior, these distinct parameters showed drastic differences in compressive strength and failure mode. This was due to the formation of interfaces between the layers of different porosities, according to the solidification configuration. The interfaces modified the fracture mode, changing from a longitudinal-directed to an interface-directed fracture. The pore microstructure and morphology indicated highly connected pore channels.

Published: December 2019

Abstract In Brazil, bentonite clays are not naturally sodic and it is an industrial practice the sodium additivation, since sodium ion expands their lamellae allowing a larger amount of water to penetrate. The objective was to analyze the influences of the use of sodium carbonate on the clay during the additivation process, the moisture content and the cure time on cation exchange and viscosity of bentonite clay dispersions for water-based drilling fluids, since there is a shortage of studies on this subject. Newly discovered bentonite clays in Paraíba State, Brazil, were chemically, physically and mineralogically characterized and were additivated with sodium carbonate in aqueous solution (process 1) or in powder form (process 2). Samples with 25% to 60% of moisture (dry basis) were prepared and submitted to cure times of 7 to 45 days. Process 1, as expected, showed better results of cation exchange capacity, viscosity and filtrate volume. The ideal cure time was 15 days. After this period there was a reversal of the cation exchange reactions.

Published: December 2019

Abstract New deposits of bentonite clays have been discovered in the Brazilian State of Paraíba; the most recent was at the municipality of Olivedos. Recent studies have discovered the presence of high levels of non-clay minerals that can produce unsatisfactory results when attempting to use these clays in drilling fluids. In order to make them suitable for this purpose, the MgO and CaCl2 as chemical additives were used and their influences on the rheological properties of these clays were analyzed, using an experimental planning technique and statistical analysis. The samples were obtained using experimental modeling by the delineation of mixtures technique; first, the clays were transformed with sodium carbonate and then dosed with MgO and CaCl2. The rheological properties, apparent viscosity (AV) and plastic viscosity (PV) were determined according to the Petrobras standard (AV≥15 cP; PV≥4 cP). The results showed that the values of AV and PV increased considerably and that MgO was the additive that contributed most to the improvement of these properties, making these additives suitable for use in water-based drilling fluids.

Published: December 2019

Abstract The study and development of ceramic composites are important because of the properties that these materials can provide, such as high dielectric constant and low dielectric loss in the RF and microwave range. Such characteristics make this type of material appropriate to several segments, such as in the telecommunication sector, especially in dielectric resonator antenna (DRA). Ceramic composites provide new materials with a range of properties that can be controlled through the phases to meet the specifications of a given application. This study aimed to synthesize and characterize the composite based on hexaferrite (BFO) and ceramics based on bismuth (BZN), aiming application as DRA. The composites were characterized by FTIR, XRD, and SEM. The composites presented a compact and heterogeneous microstructure, indicating that the sintering at 1000 °C/150 min was adequate for obtaining the ceramic composites; besides, BFO-BZNβ composite was shown to be less porous than the composite BFO-BZNα.

RESUMO O objetivo do presente estudo foi avaliar os efeitos da implantação de pastagem de sorgo forrageiro com diferentes arranjos populacionais no comportamento animal e na estrutura do pasto e de suas relações. Os tratamentos foram a combinação de dois espaçamentos entrelinhas e duas densidades de sementes ha-1, sendo 22 ou 44cm entrelinhas e 12 ou 24kg de sementes ha-1. Foram utilizadas 36 novilhas, com idade e peso corporal inicial de 15 meses e 262kg, respectivamente. Os tratamentos E44D24 e E22D12 apresentaram maior tempo de pastejo (469,33 e 467,78 minutos, respectivamente). Os animais do tratamento E44D24 apresentaram menor taxa de bocado (23,99 bocados minuto-1) em relação ao tratamento E22D24 (32,45 bocados minuto-1). Os animais do tratamento E44D12 apresentaram maior número de estações alimentares minuto-1 (9,21) e maior taxa de deslocamento (11,76 passos minuto-1). O espaçamento entrelinhas de plantio de 22cm aumenta o número de bocados estação-1. O aumento na densidade de sementes (24kg ha-1) e a utilização de maiores espaçamentos entrelinhas de plantio aumentam a densidade de folhas nos estratos inferior (0-30cm) e superior (acima de 60cm) do pasto. Os tratamentos E44D12 e E22D24 apresentaram maiores quantidades de colmos no estrato superior do pasto.

RESUMO Este artigo tem como objetivo relatar um caso de infecção por Mycobacterium bovis em um gato doméstico, com seis meses de idade, enfatizando seus aspectos clínicos e terapêuticos. O felino apresentava como histórico a ingestão de leite de vaca não fervido e posteriormente desenvolveu sinais de anorexia, tosse não produtiva e linfadenomegalia. Para elucidação do diagnóstico, foram realizados exames complementares de imagem, hematológicos, citológicos e reação em cadeia da polimerase (PCR). Diante da confirmação de infecção por Mycobacterium, o tratamento foi instituído por meio da associação de três antimicrobianos (enrofloxacino 5mg/kg, claritromicina 10mg/kg e rifampicina 15mg/kg), por via oral, a cada 12 horas, aos quais o animal respondeu positivamente, apresentando significativa diminuição dos sinais clínicos; entretanto, após 60 dias de tratamento, foi a óbito devido a um atropelamento. Conclui-se que a realização do tratamento em gatos com tuberculose pode ocasionar melhora dos sinais clínicos e que, embora de ocorrência rara no Brasil, essa enfermidade deve ser incluída como diagnóstico diferencial das enfermidades infecciosas nessa espécie.

RESUMO Avaliaram-se diferentes momentos de aplicação da gonadotrofina coriônica equina (eCG) em protocolos de inseminação artificial em tempo fixo (IATF) para vacas de leite. Foram utilizadas 76 fêmeas, as quais receberam, no dia zero (D0) do protocolo, dispositivos intravaginais de progesterona, sendo esses retirados no D9, e os animais foram, então, distribuídos aleatoriamente em três tratamentos: T1 - aplicação de eCG no momento da retirada dos dispositivos; T2 e T3 - aplicação de eCG 48h e 24h antes da retirada dos dispositivos, respectivamente. No D10 os animais receberam 1mg de GnRH, e a IATF foi realizada 52 horas após a retirada do implante. Não houve diferença (P>0,05) para intervalo entre a retirada do implante à ovulação (72,56±3,92h), o diâmetro do maior folículo no D9 (10,88±1,49mm), o diâmetro do folículo ovulatório (15,15±1,16mm) e do segundo maior folículo (7,49±0,52mm), a taxa de crescimento folicular (1,38±0,04mm/dia), a taxa de ovulação (96,67%), o intervalo entre diâmetro final e inicial do folículo dominante (73,49±3,84h), a área de corpo lúteo (2,27±0,43cm²), a porcentagem de CL no ovário direito (53,00%) e no esquerdo (26,33%) e a taxa de gestação (33,33%). O momento da aplicação da eCG não influenciou na eficiência do protocolo. Recomenda-se a utilização da eCG no momento da retirada do implante por otimização do manejo.

ABSTRACT This study aims at evaluating the effects of electrolytes, glucose and cortisol levels over heart rate (HR) and heart rate variability (HRV) in healthy newborn calves. Seventeen healthy Holstein calves were evaluated during their first month of life, and the plasma concentrations of glucose, cortisol, calcium, magnesium, inorganic phosphorus, sodium and potassium were analyzed. HRV indexes were determined in the time and frequency domains through the analysis of neonatal electrocardiogram recordings. In the first day, low blood levels of phosphorus presented a strong correlation with the HR and the increased high-frequency components of HRV. The plasma concentrations of magnesium decreased significantly throughout the 35 days, revealing a positive association with a decreasing low-frequency components of HRV at day 28. There was a strong correlation between HR, HRV indexes, some plasma electrolytes, glucose and cortisol during the studied period. Variations in the concentrations and correlations observed may be attributed to the adaptive neonatal period in calves.

ABSTRACT The aim of this paper was to evaluate the effects of including virginiamycin (VM), sodium monensin (MON) or the association (VM+MON) in the energetic mineral supplement, on the intake and performance of beef cattle on pasture. Forty Nellore heifers with 24 months of age and initial body weight (BW) of 251.5±16.6kg, were distributed in four treatments in a randomized block design. Treatments consisted of adding VM, MON or VM+MON to the supplement (CONT). Additive concentrations were defined to reach a dose of 40 to 45mg/100kg BW. The herbage allowance was not a limiting factor for the animals’ intake. Supplement intake was lower than expected, with 33.0, 18.8 and 26.3mg per 100kg BW for VM, MON and VM+MON, respectively. Dry matter intake (DMI, mean=2.65% BW) and animal performance were not affected by the inclusion of additives. The average daily gain (ADG) was 0.561kg/animal day-1. The inclusion of additives in energetic mineral supplement does not affect the DMI and the ADG of grazing animals. The variability in supplement intake and daily dose intake of additives may have influenced the performance of the animals. Monensin inclusion presented the less expensive supplementation cost, due to reduction in supplement intake without changing weight gain.

ABSTRACT The study evaluated sonographic and serologic exams performed for early (20 to 30d) diagnosis of pregnancy. One hundred-twenty (n= 120) bovine recipients were synchronized (estrous=D0) and timed embryo transferred (TET, D7) with fresh in vitro produced embryos. In the first trial (n= 46), diagnosis of pregnancy was performed on day 20 (D20) by detecting CL blood flow (BF) and by Pregnancy-Associated Glycoproteins (PAGs) serology. In the second trial (n= 30), pregnancy diagnosis was performed on D25 by ultrasound visualization of uterine contents and by PAGs serology. In the last trial, PAG’s serology was performed on D30. Ultrasonographic detection of the uterine contents and embryo viability performed on D30 (DG30) was considered the gold standard. The PROC FREQ procedure was used to test the agreement between diagnostic methods. On D20, the Doppler ultrasonography of the CL had showed high sensitivity (100%), but only moderate specificity (53.3%). On the same day, serologic diagnostic had no agreement (k= -0.08, P< 0.46) with the gold standard, with very low sensitivity (6.3%). However, the sensitivity of the serologic exam increased dramatically (from 6.3 to 100%) from D20 to D25, and it contributed to detect false negatives from the ultrasound diagnosis, improving the overall accuracy from 90% to 96.7%.

RESUMO A laminite endocrinopática tem acometido um número crescente de equinos com sinais de obesidade. Em um estudo recente com fêmeas jovens (até cinco anos) da raça Campolina, demonstraram-se indícios de alterações no dígito, ainda discretas, aparentemente associadas ao aumento da adiposidade. Com a hipótese de que essa associação é mais evidente em animais em faixa etária superior, o objetivo do presente estudo foi estudar éguas adultas (acima de cinco anos) da raça Campolina com e sem obesidade, avaliando-se radiograficamente a relação espacial entre estojo córneo e falange distal. Foram utilizadas 27 éguas entre seis e 14 anos de idade, sendo analisadas variáveis de adiposidade e medidas radiográficas dos cascos dos membros torácicos de equinos com escore corporal de 5 a 7/9 (grupo controle) e de 8 a 9 (grupo obeso). Foram feitas comparações entre os grupos e correlacionaram-se as variáveis de adiposidade com variáveis casco. A distância de afundamento da falange distal foi cerca de 20% superior nas éguas obesas (12,3±2,5 contra 10,2±2,2mm no grupo controle). Esse parâmetro também correlacionou (P<0,01) com vários parâmetros de adiposidade, com destaque para o escore de condição corporal (r=0,47) e a circunferência de pescoço a 75% (r=0,42). Os resultados corroboram estudos prévios que demonstraram associação entre obesidade e indícios de separação entre falange distal e estojo córneo em equinos de raças nacionais, comprovando, assim, a utilidade da avaliação radiográfica nesses animais. Em conclusão, éguas da raça Campolina com obesidade possuem alterações evidentes na relação espacial entre estojo córneo e falange distal, que se intensificam com o aumento da idade e da adiposidade.

ABSTRACT Paratuberculosis is a chronic and incurable disease that affects ruminants and other domestic animals. It is caused by Mycobacterium avium subsp. paratuberculosis (MAP) that may also be involved in some human diseases such as Crohn's disease, type 1 diabetes, sarcoidosis, multiple sclerosis, and Hashimoto's thyroiditis. The objective of this study was to investigate the occurrence of MAP DNA in samples of artisanal coalho cheese purchased in the State of Pernambuco. Forty samples of coalho cheese submitted to the Real Time Polymerase Chain Reaction (qPCR) technique were analyzed for the detection of the MAP region IS900. 11 (27.5%) were positive with a mean of 195.9 MAP colony forming unit (CFU) per gram of each sample, with a minimum of 30.3 CFU/g and a maximum of 324.2 CFU/g. Thus, this type of cheese that is one of the most consumed in this region of Brazil constitutes a source of human exposure to MAP. Further research in this area should be performed to evaluate the viability of the bacteria in this cheese type.

RESUMO Trueperella pyogenes é uma bactéria oportunista que causa mastite, metrite e abortos esporádicos em bovinos. Este trabalho relata um caso incomum de abort em uma vaca por Trueperella pyogenes. Um feto bovino, fêmea, mestiço Brahman, com oito meses de gestação, foi encaminhado para exame anatomopatológico e exames complementares. Na necropsia, evidenciou-se grande quantidade de líquido serossanguinolento e moderada quantidade de fibrina recobrindo a pleura visceral e o saco pericárdico. Os pulmões estavam difusamente avermelhados e consolidados, com áreas firmes esbranquiçadas ao corte de não mais de 1cm. No exame histopatológico, observou-se pneumonia necrossupurativa, pleurite fibrinopurulenta e placentite purulenta. No exame microbiológico, isolou-se T. pyogenes nas amostras de fígado, pulmões, conteúdo abomasal do feto e placenta. O feto foi negativo na PCR para Neospora caninum, Toxoplasma gondii e vírus da diarreia viral bovina (BVDV). Trueperella pyogenes geralmente causa broncopneumonia supurativa com formação de abscessos, porém, no presente feto abortado, observaram-se lesões macro e microscópicas comumente descritas em casos de aborto por Brucella abortus. Este estudo constata, então, a importância dessa bactéria como causa de aborto em bovinos, com lesões semelhantes à brucelose, destacando sua relevância dentro das causas de aborto em bovinos e o potencial zoonótico pouco explorado.

ABSTRACT Two experiments were conducted to evaluate the effect of thyme (Thymus vulgaris) essential oil (EO) doses on rumen fermentation, nutrient digestibility, and nitrogen metabolism, as well as performance and coccidia oocyst discharge. In experiment I, 20 rumen-cannulated wethers received the experimental diets containing 80% dry matter (DM) of haylage and 20% DM of concentrate. Treatments were 25mg of monensin/kg DM or doses of 1.25, 2.50, or 3.75g of thyme EO/kg DM. In experiment II, 50 ewe lambs received the same diets from experiment I, including a diet without feed additives. Wethers fed with diets containing 1.25g/kg DM of thyme EO had higher molar proportion of propionate (P= 0.03) and butyrate (P< 0.01), and lower (P= 0.04) acetate to propionate ratio than other treatments. Adding thyme EO to diets increased (P= 0.02) nitrogen retention compared to monensin. The performance of ewe lambs was not affected (P≥ 0.05) by treatments. However, lambs fed monensin had a lower (P= 0.04) number of coccidia oocyst discharge than others. Adding 1.25g/kg DM of thyme EO in high-forage diet improved ruminal fermentation. Thyme EO enhanced nitrogen metabolism, however, it did not improve performance.

RESUMO A utilização da gema de ovo dificulta a padronização de meios diluidores e apresenta riscos biológicos. Assim, este estudo avaliou diferentes concentrações da lipoproteína de baixa densidade (LDL), em substituição à gema de ovo, para a confecção de diluentes para criopreservação espermática em ovinos. Foram utilizados um diluidor controle (CTR= 20% de gema de ovo) e cinco tratamentos, substituindo-se a gema pelas diferentes proporções de LDL (T1=6%; T2=8%; T3=12%; T4=16%; T5=20%), todos à base de TRIS-glicerol. Para o estudo, utilizaram-se dois ejaculados, de seis reprodutores da raça Santa Inês. Sessenta dias após a criopreservação, as amostras foram descongeladas e avaliadas subjetivamente quanto à motilidade total (MT, %) e progressiva (MP, %), ao vigor (1-5) e à integridade funcional (choque hisposmótico com água destilada, %) e estrutural (corante supravital eosina, %) das membranas espermáticas. As avaliações de vigor e funcionalidade de membrana não diferiram (P>0,05) entre os grupos. Entretanto, os grupos T4 (P<0,01) e T5 (P<0,05) foram superiores ao CTR para os parâmetros MT, MP e integridade estrutural de membrana, o que confirma que as LDLs podem ser alternativas eficientes para substituição da gema de ovo em diluidores para criopreservação de sêmen ovino.

ABSTRACT This study evaluated how changing the structure of Brachiaria brizantha cv. Marandu pasture under different forage allowances (FA) of 4, 7, 10 and 13kg DM/100kg BW (body weight) affected animal behavior over a two-year evaluation period. The experiment was conducted as a randomized block design with three replications (paddock). Sward height, total forage, and stem mass were lower for pastures managed with lower FA. Lower leaf mass was observed for lower FA in the second year. In hand-plucked samples, leaf and stem percentages remained unchanged in the morning but leaf percentage increased while stems decreased in the afternoon. Permanence time decreased linearly with increasing FA. In turn, a quadratic effect was observed for displacement rate. The bite rate was similar among different FAs. The results demonstrate that FA varying between 7 and 10kg DM/100kg BW are more suitable to balance the amounts of leaves and stems in the sward. The studied FA levels do not limit forage availability. Permanence time decreases and displacement rate increases as FA increases.

ABSTRACT Computed tomography of the head of an otter with a history of incoordination, visual deficits, and seizures was performed. Intracranial images revealed a large non-enhancing fluid attenuating cystic lesion in the left frontoparietal region communicating with the left lateral ventricle and subarachnoid space. These findings are consistent with a congenital brain cavity filled by cerebrospinal fluid, with porencephaly being the most probable diagnosis based on the clinical and tomographic findings. The authors highlight the rarity of such a cystic lesion in wild animals, with this being the first report in otters.
