title: Respiratory and Other Health Risks among Poultry-Farm Workers and Evaluation of Management Practices in Poultry Farms

description: ABSTRACT The current study was conducted on eight poultry farms in Lahore and Sheikhupura to monitor environmental conditions, determine workers’ health status and assess the implementation of standard management practices. Environmental monitoring, a health questionnaire survey and a respiratory function test were carried out. Seventy-one respondents were selected for the health assessment survey and lung function test. The results showed that the evaluated air-quality parameters, except for temperature and humidity, were well below the permissible occupational limits. Maximum temperature recorded was 32.75 ºC, while the highest humidity level was 85.5%. Farms were shown to be compliant with standard guidelines and management practices. The workers’ health survey indicated lower prevalence of work-related symptoms as compared to previous studies. However, most workers were not subjected to overall physical hazards, 21.1% of workers suffered from heat-induced dermatosis, and 38% suffered from heat exhaustion. Eye problems (watery, redness and itchiness) were experienced by 16.9% to 31%. Reported respiratory symptoms included wheezing during colds (18.3%), wheezing other than during colds (1.4%), chest tightness (16.9%), shortness of breath along with chest tightness (9.9%), regular breathing difficulties (14.1%), and coughing (15.5%). Observed lung function pattern, as measured by FEV1/FVC ratio, was 87 ± 17.7, with 65% workers having ‘restrictive’ disorder and 21% normal lung function pattern, while 21% presented ‘obstructive’ lung function. The study concludes an overall better health and safety management in the selected poultry farms.

title: Effects of Nutritional Levels on Performance, Carcass Characteristics and Nutrient Digestibility of Sexed Broilers

description: ABSTRACT The objective of this study was to evaluate the effects of dietary nutrient levels on performance, carcass yield, commercial cuts, digestibility and economical viability of broilers from 1 to 42 days of age. During the experiment, 180 COBB 500™ chicks were housed in metal batteries and subjected to a completely randomized design in a 2x3 factorial arrangement, of two sexes and three diets (male, female and mixed), totaling 6 treatments and 6 repetitions of 5 birds each. Data were subjected to statistical analysis and the means were compared using the Tukey test, at 5% probability. The results indicate the effect of sex on performance and commercial cuts, except for breast and thigh fillets, in which males and females showed similar results when given the mixed diet. The influence of the nutritional levels on performance, digestibility and commercial cuts was observed, in which the female diet showed the highest results for feed intake, body weight and weight gain, in addition to greater retention of protein and crude energy. For drumstick and abdominal fat yield, the highest values were obtained using the mixed diet and the female diet, and the lowest values were obtained using the male diet. Regarding economic viability, the female diet showed the highest return per unit of Real (R$) spent on feed. Therefore, these data prove that the female diet had a positive effect when provided to both sexes, and it may be a promising alternative for its application at the production level.

title: Physical-Chemical Characteristics of Designer and Conventional Eggs

description: ABSTRACT The objective of this study was to compare the internal and external quality of conventional and designer eggs. In total, 120 Tetra SL laying hens were randomly allotted to two treatments (K and P groups), with 12 replicates of five hens each. The control group (K) was fed a standard layer diet, producing conventional eggs, and the P group was fed a modified diet supplemented with 5% of an oil mixture, 0.5 mg organic selenium/kg, 200 mg lutein/kg and 200 mg vitamin E/kg, producing designer eggs. Treatments did not influence (p&gt;0.05) egg weight or egg component weights. Designer eggs presented higher albumen proportion and lower eggshell proportion than conventional eggs (p&lt;0.01). Relative to egg quality parameters, designer eggs presented higher HU values (83.99 vs. 80.81; p=0.042), more intense yolk color (14.38 vs. 8.70; p&lt;0.01), and lower albumen pH (8.39 vs. 8.67; p=0.007). Feeding treatments and duration of egg storage did not significantly influence egg yolk lipid oxidation (p&gt;0.05).

title: KINETIC BEHAVIOR OF SOME AZO DYES DECOLORIZATION BY VARIATION OF ZINC OXIDE AND TITANIUM DIOXIDE CONCENTRATIONS

description: The decolorization of three monoazo dyes (acid orange 7, direct orange 34, and methyl orange), one diazo dye (direct yellow 86) and one tetraazo dye (direct red 80) were mediated by n-type semiconductors as ZnO and TiO2 under pseudo-first order conditions at 30 ºC. The decolorization rate constants of these azo dyes were determined, varying the semiconductor concentration for the majority of them from 1.0 to 10.0 g L-1. In general, the highest rate constants were displayed for ZnO. This work elucidates that the decolorization capacity depends on the charge, structure, and adsorption of the azo dye on the semiconductor surface as well as the agglomeration of the photocatalyst particles.

title: Growth curve for height at withers of Mangalarga Marchador horses with heterocedasticity

description: ABSTRACT This work aimed to evaluate the fit of models Brody, Gompertz, Logistic and Von Bertalanffy to height at the withers of Mangalarga Marchador horses, weighed by the inverse of variance, in order to select the best model and predict growth and maturity of this breed pf animals. We used data of 230 equines from 06 to 176 months of age who were divided by sex and 16 age classes. The models were compared according to the quality assessors: coefficient of determination (R2); residual standard deviation (RSD) and Akaike information criteria (AIC). The estimation of the parameters from models was performed by the weighted least squares method in Software R. All models evaluated were suitable to describe the growth curve in both sexes. In view of the evaluators used, the logistic model was the most suitable to describe the growth curves in withers height in both sexes for the race Mangalarga Marchador. A strong growth at first age was also observed. The males reached a greater adult height, but females did so sooner, because they presented higher estimates for the maturity index.

title: Impact of the Assimilation of Metop-B Satellite Refractivity Profiles in the Forecasts of the CPTEC/INPE During the Months of January and August 2014

description: Abstract Currently, there is an increase in the number of low orbit satellites dedicated to radio occultation of GPS signals. The MetOp-B is one of these new satellites, but it has not been explored in the data assimilation performed in Brazil. In order to include this source of observation in the database used in the assimilation of the CPTEC/INPE and evaluate its impact in the performance of the Atmospheric Global Circulation Model used operationally at the center, an experiment with data from January and August 2014 was executed. The results were compared with another experiment without assimilating those data, which showed that the inclusion of the MetOp-B refractivity profiles, has impacted beneficially the assimilation of more data from the other satellites in use, such as COSMIC, TerraSAR-X and MetOp-A. The most prominent results were observed in August, with root mean squared gain values greater than 40% in the state variables for the 24-h forecast over the Southern Hemisphere, variables that are directly related to the refractivity values. Beyond that, the anomaly correlation coefficient values over South America indicated that, adding the MetOp-B data, the zonal and meridional wind components at 250 hPa were indirectly impacted, showing the importance of assimilate such data.

title: CONSIDERATIONS ABOUT THE RETEXTUALIZATION PROCESS OF TEXTS IN PORTUGUESE FOR LIBRAS BY DEAF UNDERGRADUATES

description: ABSTRACT: The purpose of this paper is to discuss the retextualization process of texts in Portuguese for the Brazilian Sign Language (Libras) by deaf students. For this, among other authors, we are theoretically based on the considerations of Travaglia (2013, 1993) and Marcuschi (2010 [2000]), about the retextualization process, understood, respectively, as a translation, from a textual perspective, and as a transformation of texts in the same language. We also highlight the considerations of Karnopp and Quadros (2007), on linguistic aspects of the Brazilian Sign Language. Methodologically, we analyzed the retextualization process in signalized and videotaped texts produced by undergraduates of Letras-Libras Course of UFPI, from an activity performed in the Methodology of Human Sciences Research discipline, given in the second period of 2014. The analysis of data indicated that the modality of the Brazilian Sign Language requires of the translator/interpreter, more than ability to produce texts, because, in translation process for Libras, the linguistic elements of portuguese are transformed in linguistic elements of the Libras. Thus, the information from the original text, written in Portuguese, will reappear transformed into the retextualized text, signalized in Libras, but this information is organized from the linguistic structure of the Libras and resignified from the deaf interpretation of the original text written in portuguese.

title: Comparison of Gut Microbial Diversity in Beijing Oil and Arbor Acres Chickens

description: ABSTRACT The Beijing oil (BJO) chicken is an autochthona Chinese breed which shows outstanding meat quality characteristics compared with fast-growing imported chickens such as Arbor Acres (AA) chickens. Gut microbial diversity has been shown to influence host factors such as energy and nutrient metabolism, immune response and fertility. Consequently, it is hoped that analyses into host microbial populations will ultimately help to improve the quality of associated meat products. Two distinct chicken breeds, Arbor Acres (AA) and Beijing oil (BJO), were selected to analyze the composition of the 16S rRNA gene V3-V5 hypervariable regions using high-throughput sequencing technology. Upon elucidation of gut-colonizing bacteria, the Firmicutes were observed to encompass the dominant phylum. The abundance of Firmicutes in the BJO chickens (84.9%) was lower than in the AA chickens (89.9%). Conversely, the prevalence of Proteobacteria was 4.8% in BJO chickens, with a significantly lower abundance observed in AA chickens (1.3%). In the cecum, the Firmicutes were once more the dominant phylum in BJO chickens (60.2%) and AA chickens (63.7%). The abundance of bacteroidetes was 37.7% in BJO chickens and 34.9% in AA chickens, respectively. These discoveries provide a perception into the composition of the gut microbiotain both breeds. The study also provides a foundation for future research relating to gut bacterial factors that may influence the development and progression of gastrointestinal disease in chickens and other animals.
