Abstract: Objetivou-se com esse trabalho avaliar o gerenciamento da bovinocultura leiteira nas propriedades de economia familiar e tra ar estratégias gerenciais para a produ o. Neste trabalho foram estudadas três propriedades na regi o noroeste do Estado do Paraná, classifi cadas em alta, média e baixa tecnifi ca o. Foram colhidos dados de manejo geral, nutricional e índices reprodutivos. Na de alta tecnifi ca o o rebanho recebia ra o total misturada, com silagem de milho e ra o concentrada produzida na fazenda. Após a ordenha eram liberadas para os piquetes formados com grama estrela (Cynodon nlenfuensis). O intervalo entre partos médio do rebanho era de 14,65 meses. Recomendou-se a sele o de animais mais prolíferos. Na propriedade de média tecnifi ca o, a ra o foi formulada por um representante comercial, era misturada no ch o com auxílio de uma enxada e continha falhas na formula o, pois n o fechava em 100%. A exigência de energia líquida para lacta o n o era suprida, além deoutros défi cits, refletindo nos índices reprodutivos dos animais. Recomendou-se o fornecimento de dieta cujas exigências eram atendidas. Na propriedade com baixa tecnifica o, a ordenha era realiza manualmente uma vez ao dia. A dieta fornecida possuía déficit de Ellac, NDT, PB, fra es da proteína e de extrato etéreo. Nesta propriedade recomendou-se a mudan a da dieta, plantio de novas forrageiras e a efetiva manuten o das anota es zootécnicas.Concluímos neste estudo que o défi cit energético leva ao retardamento da volta ao ciclo no pós-parto das vacas e, conseqüentemente, piora dos índices reprodutivos do rebanho. = The objective of this study was to evaluate the management of dairy cattle on family based economy and to defi ne strategies for production. Three proprieties from the Northeast of the region of the State of Paraná, Brazil, which were classifi ed as elevated, average, and low technology, were evaluated. Information relative togeneral management, as well as nutritional and reproductive indices were obtained. In proprieties of elevated technology, the animals received a completely mixed ration, which contained corn silage and concentrate. After milking, these animals were maintained in corrals containing star grass (Cynodon nlenfuensis). In these proprieties,the average calving interval was 14.65 months, and it was recommended that proliferous animals be selected. In those proprieties classifi ed as average technology, the feed was formulated by a commercial representative, spademixed on the floor, and had defective formulation, since the total did not arrive at 10

Abstract: during the reproductive season of 2001 and 2002, 43 recipient mares of the mangalarga marchador breed were treated randomly with intra-muscular application of 200mg/day of oily progesterone (p4). another group of 41 mares of the same breed were treated randomly, via oral, with 0.044 mg/kg/day of altrenogest. both treatments were performed between d0 (ovulation day) and d5. the recipients were evaluated on d2 and those in adequate conditions were in ovulated. two groups of 85 mares of the same breed were used as control by not receive any progestogen. they were also evaluated and, when considered appropriate, in ovulated on d2 or d5. the groups d2/p4 and d5 without progestogen presented a significantly greater percentage of recipients considered appropriate during the evaluation, respectively 55 (64.71%) and 25 (65.12%). in the group d2 with altrenogest, 20 mares were considered appropriate for in ovulation and 21 were not. the group d2 without progestogen showed a significantly higher percentage of mares considered not appropriate. the pregnancy rate after in ovulation for the groups d2/p4 and d5 without progestogen were respectively 72.72 and 76.36%, significantly higher than those from the other treatments. the pregnancy rate for the group d2 with altrenogest (52.38%) was not significant. despite a larger number of non pregnant recipients for the group d2 without progestogen, it was not significant. the treatment of mares with p4 from d0 to d5 indicates it is possible to anticipate the in ovulation of recipient mares to d2 and to obtain similar results to when in ovulated on d5.

Abstract: A database containing 910 individual records of sand fly occurrence in the state of S?o Paulo, from 37 different sources, was compiled. These records date from between 1943 to 2009, and describe the presence of at least one of the six incriminated or suspected sand fly vector species in 183/645 (28.4%) municipalities. For the remaining 462 (71.6%) municipalities, we were unable to locate records of any of the six incriminated or suspected sand fly vector species (Nyssomyia intermedia, N. neivai, N. whitmani, Pintomyia fischeri, P. pessoai and Migonemyia migonei). The distribution of each of the six incriminated or suspected vector species of ACL in the state of S?o Paulo were individually mapped and overlaid on the incidence of ACL for the period 1993 to 1995 and 1998 to 2007. Overall, the maps reveal that the six sand fly vector species analyzed have unique and heterogeneous, although often overlapping, distributions. Several sand fly species - Nyssomyia intermedia and N. neivai - are highly localized, while the other sand fly species - N. whitmani, M. migonei, P. fischeri and P. pessoai - are much more broadly distributed. ACL has been reported in 160/183 (87.4%) of the municipalities with records for at least one of the six incriminated or suspected sand fly vector species, while there are no records of any of these sand fly species in 318/478 (66.5%) municipalities with ACL.The maps produced in this work provide basic data on the distribution of the six incriminated or suspected sand fly vectors of ACL in the state of S?o Paulo, and highlight the complex and geographically heterogeneous pattern of ACL transmission in the region. Further studies are required to clarify the role of each of the six suspected sand fly vector species in different regions of the state of S?o Paulo, especially in the majority of municipalities where ACL is present but sand fly vectors have not yet been identified.Phlebotomine sand flies are dipteran insects and some species are vectors

Abstract: Neste trabalho s o apresentados os resultados relativos à proposta para a amplia o do programa de coleta seletiva no município de S o Jorge do Ivaí, estado do Paraná, Brasil. A metodologia contempla aplica o de questionário, visita ao barrac o de triagem, caracteriza o gravimétrica de resíduos e confec o de mapa de zoneamento da coleta seletiva. A coleta seletiva atual foi implementada pela prefeitura municipal por meio de um projeto piloto na regi o central do município. Estima-se a coleta de 1,12 t mensal de resíduos com a participa o de 30% da popula o do município. No entanto, as estimativas aqui realizadas indicam a gera o diária de 6,0 t de resíduos sólidos urbanos com 20% (1,18 t diário) passíveis de reaproveitamento e reciclagem. Desse modo, se justifica a amplia o da coleta seletiva no município e as necessidades básicas para a realiza o dessa implanta o s o aqui descritas. = This paper presents the results for the proposed to expand the program of selective collection in the S o Jorge Ivaí, Paraná, Brazil. The methodology involved questionnaires, visits to the shed screening, characterization of wastes and gravimetric preparation of zoning map of the collection. The current selective collection was implemented by the municipal government through a pilot project in the central city. It is estimated to collect 1.12 tons per month of waste with theparticipation of 30% of the population of the municipality. However, the estimates made here indicate the daily generation of 6.0 tons of waste with 20% (1.18 t/day) capable of reusing and recycling. Thus, there is justification for expanding the collection at the county and the basic needs for the completion of this deployment are described here.

Abstract: this work aimed to quantify the dry matter production and the contents of b, ca and mg in soybean plants grown in soils with different textures, which received increasing doses of b, and liming. additionally, it was correlated the b contents in the plants with the b recovered from the soil with boiling water and cacl2. the experiment was carried out in a greenhouse in a factorial 3 x 2 x 6 (three soils: sand texture (rq), loamy sand (lva1) and clayey (lva2) textures; with and without liming; and six b doses: 0; 1,5; 3; 6; 9 and 15 mg dm-3) arranged in a entirely randomized block design with three replications. it was determined the soil b extracted with boiling water and cacl2 45 days after the addition of the b doses to the soil. the shoots dry matter weight and theer b contents in the soybean plants were determined. the mean concentrations of b recovered by both boiling water and boiling cacl2 were similar for the three soils and were highly correlated with the b contents in the plants and with the dry matter production. the b doses added increased b concentration in the plants, but they decreased dry matter production in the rq soil, and in the lva 1 and lva2 soils with liming. the detrimental effect of high b in the dry matter production was lowered in the soils with higher clay and organic matter concentrations.

Abstract: the eutrophication of aquifers is strongly linked to the mobility of p in soils. although p mobility was considered irrelevant in a more distant past, more recent studies have shown that p, both in organic (po) and inorganic forms (pi), can be lost by leaching and eluviation through the soil profile, particularly in less weathered and/or sandier soils with low p adsorption capacity. the purpose of this study was to determine losses of p forms by leaching and eluviation from soil columns. each column consisted of five pvc rings (diameter 5 cm, height 10 cm), filled with two soil types: a clayey red-yellow latosol and a sandy loam red-yellow latosol, which were exposed to water percolation. the soils were previously treated with four p rates (as kh2po4 ) to reach 0, 12.5, 25.0 and 50 % of the maximum p adsorption capacity (mpac). the p source was homogenized with the whole soil volume and incubated for 60 days. after this period the soils were placed in the columns; the soil of the top ring was mixed with five poultry litter rates of 0, 20, 40, 80, and 160 t ha-1 (dry weight basis). treatments consisted of a 4 x 5 x 2 factorial scheme corresponding to four mpac levels, five poultry litter rates, two soils, with three replications, arranged in a completely randomized block design. deionized water was percolated through the columns 10 times in 35 days to simulate about 1,200 mm rainfall. in the leachate of each column the inorganic p (reactive p, pi) and organic p forms (unreactive p, po) were determined. at the end of the experiment, the columns were disassembled and p was extracted with the extractants mehlich-1 (hcl 0.05 mol l-1 and h2so4 0.0125 mol l-1) and olsen (nahco3 0.5 mol l-1; ph 8.5) from the soil of each ring. the pi and po fractions were measured by the olsen extractant. it was found that under higher poultry litter rates the losses of unreactive p (po) were 6.4 times higher than of reactive p (pi). both the previous p fertilization and increasing poultry

Abstract: in highly weathered tropical soils the diffusive flux is the main transport mechanism of zn, cu, fe, and mn to the root surface of plants. management practices such as liming and the presence of plant residues can alter the diffusive flux of these cationic micronutrients. the aim of the present study was to evaluate the diffusive flux in anionic and cationic forms and bioavaiability of cationic micronutrients zn, cu, fe and mn in oxisols with distinct textures as influenced by liming doses, in the absence and presence of plant residues. two plant materials widely used as green manure - guandu bean and millet - were incorporated into two oxisols (a loamy-sand red yellow latosol - lva and a clayey red latosol - lv). the diffusive flux was evaluated using a positively charged anion exchange resin membrane and a negatively charged cation exchange resin membrane. the membranes were incubated with the soils for 15 days. results showed that liming reduced the diffusive flux of the cationic micronutrients. the presence of green manures attenuated this negative effect of liming on zn, cu, fe and mn transport. cu and fe were transported predominantly in the anionic form, whereas zn and mn did mainly in the cationic form. the addition of green manure also raised the soil ph, and improved the absorption of cationic micronutrient by corn plants, especially when millet was incorporated into the lva and guandu bean into the lv.

Abstract: the objective of this study was to characterize the the microclimatic profile of broiler chicken transport trucks under commercial conditions, in the winter by continuous monitoring of environmental variables (temperature and relative air humidity) and deaths on arrival (doa's). three loads were monitored, from farm to slaughterhouse, considering factors such as distance (short, medium and long) and periods of the day (morning, afternoon and night). to obtain the environmental variables profile in the trucks during the journey, data loggers were installed in the trucks that determined the microclimate to which the birds were submitted and allowed the visualization of the enthalpy comfort index (eci) so that the lorry regions could be classified according to heat comfort limits for six-week old poultry. the temperature, relative humidity and eci in the truck were analyzed using geostatistics, by the ordinary kriging method. the afternoon was the most critical period from the environmental point of view, and the central and rear parts of the truck were most problematic for the chickens from the microclimatic point of view and were thus the most susceptible to losses.
