Correlação entre a densidade mineral óssea e níveis séricos de cálcio, fósforo e fosfatase alcalina total em gatos após tirotoxicose experimental

Hyperthyroidism is and endocrinal dysfunction characterized by excessive serum concentrations of thyroid gland hormones, which can cause several effects on the bone tissue in humans and in animals. For a better characterization of thyrotoxicosis effects on bone metabolism, 16 cats were induced into hyperthyroid state. Results showed that, in some moments a major bone demineralization of the right distal radium estremity promoted an elevation of the serum levels of phosphorus and total alkaline phosphatase.

Níveis de cálcio e avaliação óssea e de ovos de avestruzes reprodutoras

Analyses of mineral density in tibias and femurs of breeder ostriches had been carried on six couples 5-7 years old. During 8 weeks, 3 couples had been fed with ration of reproduction (T1) and other 3 couples with ration of maintenance (T2). It was possible to verify that the egg production was not affected by the diets, as well as the quality of egg shells. However the quality of the bones was worse for the birds fed of T2.

Digestibilidade e tempo de trânsito gastrintestinal de dietas contendo níveis crescentes de fibra bruta para pacu

This work aimed to evaluate the effect of increasing dietary fiber levels on the digestibility and gastrointestinal transit time (GTT) for pacu. The digestibility trial used 288 pacu in a completely randomized design, fed in aquaria and transferred to a modified Guelf-type feces collector, using the partial sampling method. The inert marker on the diets was chromic oxide (1%) to establish the diet digestibility. In the GTT assay, 288 pacu were distributed in 24 aquaria in a completely randomized design. Fish were fed with two colored diets - green and white - and feces color was determined after abdominal pressure. The white and green diets used 1% of titanium and chromic oxides, respectively. Total GTT was determined when all fish showed green feces. The apparent digestibility coefficients and GTT of diets decreased as dietary fiber levels increased. These results indicated that 9% dietary fiber can be used in pacu diets without negative effects on energy, protein, crude fiber and ether extract digestibility and GTT.

Diferentes níveis de betaína sobre incidência de diarreia, desempenho, características de carcaça e parâmetros sanguíneos de suínos

Thirty six piglets weaned at 19 days of age were useddistributed in a randomized block design, were used to evaluate the effects of the addition of crescent levels of betaine (0,0%, 0,1%, 0,2% e 0,3%) in the diets on the performance in initial, growing and finishing phases. The indexes of diarrhea incidence were monitored in the first 14 days post-weaning; and the blood parameters at 20, 75, and 150 days of age, as well as the carcass characteristics at the end of the experiment. It was not observed (P > 0,05) effect of the betaine on the diarrhea incidence. Significative differences (P < 0.05) were verified among treatments in the finishing phase for daily weight gain and feed conversion. Differences (P < 0.0001) among the days to the blood parameters analysed were also observed. In regard to the backfat thickness, it was verified significative difference (P < 0.05) among the treatments.

Avaliação dos níveis de frutosamina em gatos sob estresse agudo e crônico

Fructosamine are glycated serum proteins that are formed continuously due to the reaction between glucose and circulating proteins, and corresponding to the blood glucose control assessment over the last one to two weeks in cats. The fructosamine concentration has been used for differentiation between persistent and transient hyperglycemia. Therefore, the determination of fructosamine is considered the gold standard for monitoring glycemia into control in diabetic cats. The objective of this study was to evaluate the influence of acute and chronic stress of cats on serum fructosamine. 62 cats were selected from the Veterinary Hospital of FMVZ - UNESP, Botucatu campus. They were distributed into three groups: cats with a history of any illness or stress condition, excluding Diabetes Mellitus (DM), for a maximum of 48 hours (Group A, n = 21) or for a period exceeding 120 hours (Group B n = 27). The third group (Group C = control) was formed by 14 health cats. The groups were evaluated for serum fructosamine, glucose, protein and albumin. In this study, there was a significant increase in the values of fructosamine in animals subjected to acute and chronic stress, but these values remained within the reference range. The animals were, on average, normoglycemic, despite the positive correlation between fructosamine and glucose concentrations. We conclude that the fructosamine concentration is influenced by acute and chronic stress in cats, remaining, however, within the reference range, and therefore, still useful in the diagnosis of DM.

Distribuição e abundância de larvas de Simulium spp.em córregos do estado de São Paulo nos diferentes níveis de qualidade da água

The aim of this work was to determine the distribution and abundance the species of Simulium: in 5 streams of the north coastal region of the state of São Paulo. Simulium larval and water samples were collected every 2 weeks in summer and winter, 2001. The larval were collected on artificial substrates (triplicate) preserved in alcohol (70%) and after analyzed quantitative and qualitative. From the streams the values of temperature, dissolved oxygen, conductivity, pH and stream discharge were measured. The contents of total nitrogen and dissolved nitrogen, ammoniacal nitrogen, nitrate, nitrite, orthophosphate, dissolved phosphorus and total phosphorus were determined in the laboratory. Water quality has great influence in the distribution and abundance of the species. S. pertinax was more abundant in streams without or with low levels of pollution, S. inaequale in streams more polluted and S. incrustatum in intermediary levels of pollution. S. pertinax was the species more abundant with 57.5% of presence in the samples, the second more abundant was S. inaequale with 42.1% of presence and S. incrustatum was rare with 0.4% of presence. The larval abundance was lower in the polluted environment. © 2012 by Unisinos.

Níveis de fertirrigação na avaliação das características morfofisiológicas em mudas de pimenta malagueta

O presente trabalho teve o objetivo de avaliar as características morfofisiológicas de mudas de pimenta malagueta (Capsicum frutescens) sob diferentes níveis de fertirrigação, utilizando-se fertilizante líquido 10-10-10 (N-P-K). O experimento foi realizado na Faculdade de Ciências Agrárias da Universidade Federal da Grande Dourados. O delineamento experimental foi em blocos casualizados (DBC), com seis doses de fertilizante líquido (0; 2,5; 5,0; 10,0; 20,0 e 40 mL L-1) diluídos na água de irrigação e quatro repetições. As mudas foram produzidas em viveiro telado, em bandejas de 128 células preenchidas com substrato. Realizou-se uma fertirrigação, aos 15 dias após a semeadura ( DAS). Avaliou-se, aos 30 dias após a semeadura, o número de folhas, o comprimento da parte aérea e da raiz, a massa fresca e seca da parte aérea e da raiz, a área foliar e o teor de clorofila. A dose de 25 mL L-1 do fertilizante líquido 10-10-10, aplicada via fertirrigação, é recomendada para a produção de mudas de pimenta malagueta, embora tenha havido aumento da massa seca de raízes e parte aérea em dose maior.

Características morfoagronômicas do milho submetido a diferentes níveis de desfolha manual

The present study was conducted to evaluate the damage caused by defoliation in maize. The experiment was carried out in 2005/2006 at Roma Farm, Ituverava-SP, using the triple hybrid CODETEC 304®. The experiment consisted of split plots (split-plot), which were distributed at random in three blocks, with the main treatment manual defoliation (30%, 40%, 60% and 80% defoliation) in the plots and as the secondary treatment the phenological phases (D1, D2 and D3) with three replicates for each treatment and a control plot (0% defoliation) for each block. It was evaluated the production of plots (g/m2), the average size of the spikes (cm) and the average weight of thousand grains (g). According to the results, it was concluded that the source-sink relations were negatively affected, and the treatment with 80% defoliation was the one that most affected all variables, thus, it is a level of defoliation that is responsible for the largest losses, with no means of compensation for the maize crop.

Desempenho e morfometria duodenal de frangos de corte submetidos a diferentes níveis de energia e programas de alimentação de 42 a 57 dias de idade

This experiment was conducted to evaluate the use of different energy levels and amino acid recommendations on performance, carcass yield and intestinal morphometry of broilers from 42 to 57 days of age. We used 1,600 one-day old male broilers (Cobb 500) in a completely randomized design arranged in a 2x4 factorial scheme with 3,200 and 3,600 kcal ME/kg and four different feed programs. The metabolizable energy levels and the feed programs did not determine significant differences in carcass characteristics for choosing a level of energy or a feed program, thus the energy level and the recommendations of amino acids that determine the highest cost-benefit ratio should prevail. It was observed that 3,600 kcal ME/kg resulted in some improvement on performance and morphometry of the intestinal mucosa, also the fractioning of digestible amino acid requirements during two periods resulted in worse performance and intestinal villi height.

Distribuição de fisioterapeutas entre estabelecimentos públicos e privados nos diferentes níveis de complexidade de atenção à saúde

Background: The Brazilian Health System is organized on a regional and hierarchical form with three levels of complexity of health care. The Primary Care represents the first element of a continuing health care process, complemented by specialized actions. However, the centrality of the specialized care is still a problem in Brazil, especially in the private sector. Studies on the distribution of professionals in the health system allowing the formulation of appropriate policies are needed. Objectives: To investigate the distribution of physical therapists in the levels of complexity of health care and between public and private establishments, according to data from the National Register of Health Service Providers (NRHSP). Method: A descriptive cross-sectional study was performed considering NRHSP-national bank data collected in March 2010 and demographic census 2010 data. Data were analyzed through descriptive statistics techniques. Results: We identified 53,181 registries of physical therapists, 60% linked to the private sector. Only 13% of all entries were linked to primary care. The predominance in specialized care occurred in the public sector (65%) and private sector (100%). The specialized establishments of private sector linked to the southeast region (16,043) were the main sites of physical therapists. Only the public sector in the south had a majority in the Primary Care. When considering the sizes of the cities, there is focus on specialist care in bigger cities. Conclusions: This study identified the concentration of physical therapists in the specialized care, mostly in metropolis and big cities and in the private sector, with restricted to participation in the primary care.

Resposta da alface à aplicação de biofertilizante sob dois níveis de irrigação

The use of biofertilizers is interesting for agriculture as being an economical alternative as well as it is environmentally friendly by using organic waste and reducing the application of mineral fertilizers. The aim of this study was to evaluate the effect of biofertilizer doses of bovine origin (biodigester effluent) applied on the ground and two levels of irrigation on lettuce. The experiment was conducted under protection of a greenhouse in pots, applying to the soil different doses of biofertilizer of bovine origin obtained from anaerobic reactor (10, 20, 40 and 60 m3 ha-1) and mineral fertilizer as a witness in two irrigation levels calculated at 50 and 100% of reference evapotranspiration. The lettuce plants were analyzed in their: Height, leaves number, crown diameter, fresh weight and dry weight of shoots. The biofertilizer treatments showed better results than the mineral fertilizer and has increased with increasing doses of biofertilizer, the highest dose (60 m3 ha-1) showed the best results in all variables. For dry, mineral fertilization showed higher values. The irrigation levels had no effect on plant growth.

Efeito do manejo e de níveis de lodo de esgoto na fertilidade do solo após tres aplicações

The agricultural use of sewage sludge as organic fertilizer is considered nowadays as on alternative of disposal, in the end of the residue in addition to possible environmental problems, it's using can decrease the mineral fertilizers and avoid provide organic matter to the soil. The objective of this study it was to evaluate the parameters of soil fertility under different managements and doses of sewage sludge after the third application of the residue. The experiment was carried out in São Manuel - SP, with the cultivation of sunflower in two consecutives cycles, followed by wheat and triticale without application of the residual, and in the following year with the application of sewage sludge and cultivated the black oats. It was adopted a randomized complete block design, consisting of six treatments and five repetitions defined as follows: T0 - without fertilization; T1 - mineral fertilizer nitrogen according to crop need, T2 - 50% of N from sewage sludge and 50% in mineral form, T3 - 100% of N from sewage sludge, T4 - 150% of N from sewage sludge, T5 - 200% of N derived from sewage sludge. Soil samples were collected in the end of the trial of oats. There were an increase in the levels of P, H + Al, CEC and OM, B, Cu, Fe, Mn, Zn as a function of increasing dose of sewage sludge. To V% and pH were decreased the values in the proportional soil to the increase of sludge dose until 24 and 22 t ha-1, respectively and after increasing the pH and V%.
