ABSTRACT Determining what and how much each environmental factor affects pregnancy is crucial to the sustainability and management of beef cow herds. The study evaluated through logistic regression the effect of environmental variables on the increase or reduction in the pregnancy rate of beef cows. The average pregnancy rate in the cows was 73 %, with an average age for the herd of 3.7 years. An increase in age of one year represented a 30 % increase in pregnancy, while a reduction of one year reduced the odds of pregnancy in the cows by 23 %. During the lactation period, an extra seven days’ lactation reduced the odds of pregnancy by 12 %. For every seven days that weaning was brought forward, the cows’ pregnancy odds increased by 14 %. An increase of 0.1 kg in average daily gain represented an increase of 17 % and 15 % in the odds of pregnancy during the first 60 days post-partum and 60 days to the end of the reproductive period. On the other hand, the loss of 0.1 kg in average daily gain resulted in a 14 % and 13 % reduction in the cows’ pregnancy odds, respectively. Factors such as age, the precocity of calving in the calving season, the time the calf remains with the cow and better performance in cows between calving and the end of the mating are strategies that increase the chances of pregnancy in beef cows.

Abstract Potential variables for the reproductive success of beef cows were evaluated. Included in the model were the age of the cow at calving; the interval between the Julian calving date and the end of the breeding season; the body weight and conditions at calving, at 75 days post-partum and at the end of the breeding season; and the mean daily variation in weight between these dates. Logistic regression was used in the analysis, with the parameters evaluated using the odds ratio statistic, estimating the chance of pregnancy. The mean rate of pregnancy was 84% and 55% for early and late-weaned cows, respectively. For early weaned cows, the regression variables were the Julian calving date, age of the cow, weight gain from calving to 75 days post-partum, and from 75 days post-partum to the end of the reproductive period. For late-weaned cows, there were only two regression variables, weight at calving and weight gain from calving to the end of the reproductive period. For every year above the average age of the herd, early weaned cows have an 80.9% greater chance of pregnancy, while a reduction of one year reduces the chance of pregnancy by 44.7%. In early weaned cows, every seven days after the mean Julian calving date reduces the chances of pregnancy by 22.6%, whereas every seven days before the mean calving date increases pregnancy by 29.2%. Greater gains in cow body weight, from calving to the end of the reproductive period, determine a greater probability of pregnancy.

Abstract The aim was to identify the predominant variables in the differentiation of meat quality of cattle submitted to surgical castration, immunocastration, or non-castration and finished in a tropical pasture. Thirty-nine crossbred cattle were used and distributed in three treatments: i) surgical castration; ii) immunocastration; and iii) non-castration, with an initial mean age of 14.06±0.72 months and a mean weight of 284.10±31.40 kg. We used the principal component analysis to differentiate the qualitative meat characteristics between the treatments. Based on that analysis, we found that the first three principal components explained 71.44% of the total variation in the meat quality data, which ensures that the variation found is associated with the effect of the treatments. The characteristics correlated with the first three principal components and responsible for the discrimination between sexual conditions were subcutaneous fat thickness, instrumental meat color, cooking loss and shear force. These characteristics were similar among castrated animals, regardless of the methods. Therefore, immunological castration preserves the attributes of the meat and prevents possible damage to the physical and mental integrity of the animals. Finally, principal component analysis is an important methodology in the objective investigation of beef meat attributes.

RESUMO: A esporotricose é uma micose subcutânea de evolução subaguda a crônica, causada pelo fungo dimórfico e geofílico Sporothrix schenckii. A transmissão zoonótica vem recebendo destaque, tendo os felinos domésticos um importante papel epidemiológico na doença. Este trabalho pesquisa teve como objetivo diagnosticar casos de esporotricose em felinos domésticos atendidos no município de Campos dos Goytacazes/RJ, bem como correlacionar os casos positivos com os sinais clínicos observados nos mesmos, assim como fatores de risco tais quais sexo, animais castrados ou não, dentre outras características. Foram utilizados 100 felinos domésticos, portadores de lesões cutâneas suspeitas de esporotricose, os quais passaram por avaliação clínica minuciosa e preenchimento de fichas individuais. As lesões foram então selecionadas para coleta de material em suabes estéreis e posterior análise laboratorial, através da citologia e cultura fúngica. Dos 100 animais analisados, 66 (66%) foram positivos para Sporothrix spp., sendo 46 (69,6%) machos não castrados, 15 (22,7%) fêmeas não castradas, 4 (6,06%) fêmeas castradas e 1 (1,5%) macho castrado, os quais 89,3% tinham acesso à rua. Quanto à topografia lesional e estado clínico dos animais, 43 (65,2%) apresentavam lesões focais e 23 (34,8%) lesões disseminadas, onde 21 (31,8%) vieram à óbito ou foram submetidos a eutanásia por opção do tutor. Com os resultados dos exames foi possível a adequada prescrição do protocolo terapêutico e acompanhamento de 40 animais (60,6%), e nos casos dos felinos encaminhados (7,5%), foi reportado ao médico veterinário responsável o respectivo diagnóstico para que este escolhesse sua conduta terapêutica.

ABSTRACT: Sporotrichosis is a subcutaneous mycosis of subacute to chronic evolution, caused by the dimorphic and geophilic fungus Sporothrix schenckii. The zoonotic transmission has been highlighted, with domestic cats having an important epidemiological role in the disease. This research aimed to diagnose cases of sporotrichosis in domestic cats treated in the city of Campos dos Goytacazes/RJ, as well as to correlate the positive cases with the clinical signs observed in them, as well as risk factors such as sex, castrated animals or not, among other characteristics. One hundred domestic felines were used, with skin lesions suspected of sporotrichosis, which underwent a thorough clinical evaluation and completion of individual files. The lesions were then selected for material collection in sterile swabs and subsequent laboratory analysis, through cytology and fungal culture. Of the 100 animals analyzed, 66 (66%) were positive for Sporothrix spp., Being 46 (69.6%) uncastrated males, 15 (22.7%) uncastrated females, 4 (6.06%) females castrated and 1 (1.5%) castrated male, 89.3% of whom had access to the street. Concerning the lesion topography and clinical status of the animals, 43 (65.2%) had focal lesions and 23 (34.8%) disseminated lesions, where 21 (31.8%) died or were submitted to euthanasia at the option of tutor. With the results of the exams, it was possible to adequately prescribe the therapeutic protocol and follow up of 40 animals (60.6%), and in the cases of the cats referred (7.5%), the respective veterinarian was informed of the respective diagnosis so that this To choose their therapeutic behavior.

PURPOSE: To evaluate and correlate the amplitude of esophageal contractions triggered by swallowing water with dynamic extension and habitual, strong and weak sound intensity in total laryngectomees wearing a tracheoesophageal prosthesis. METHODS: Thirty total laryngectomees using tracheoesophageal voice with a phonatory prosthesis were evaluated by measuring the amplitude of contractions in the proximal, middle and distal esophagus and the pressure of the pharyngoesophageal transition by manometry. In order to measure vocal intensity the subject was asked to emit phonation of the vowel /a/ at habitual, strong and weak intensity which was captured with a sound pressure meter. Dynamic extension was calculated by subtracting strong intensity from weak intensity. RESULTS: A positive correlation was observed between contraction amplitude and dynamic extension in the proximal (rho: 0.45; p=0.01) and distal (rho: 0.41; p=0.02) esophagus There was no correlation with other parameters.. Total laryngectomees wearing a phonatory prosthesis with a dynamic extension above 21 dBNPS had greater contraction amplitude than laryngectomees with a dynamic extension below this value. CONCLUSIONS: There was a positive correlation between pressure amplitude in the proximal and distal esophagus and increased dynamic extension. The individuals with normal dynamic extension had greater contraction amplitude in the proximal esophagus than individuals with dynamic extension lower than the expected values for age.
