RESUMO. O objetivo foi avaliar o desempenho, peso relativo de órgãos, morfometria, comprimento intestinal e atividade de enzimas pancreáticas de frangos de corte recebendo suplemento neonatal. Foram utilizados 900 pintos de corte da linhagem Cobb 500, alojados em 30 boxes de 2,5 m². Os tratamentos foram divididos em delineamento inteiramente casualizado, com seis repetições, e consistiram em cinco níveis de inclusão (0,0; 2,5; 5,0; 7,5 e 10 gramas por ave). O suplemento utilizado foi à base de aminoácidos, vitaminas e minerais, o qual foi fornecido no primeiro dia de alojamento sobre a ração. A análise estatística foi realizada utilizando o SAS (2008) e quando significativos desdobrados em regressão polinomial. Em função da inclusão do suplemento neonatal no período de um a sete e de um a 21 dias de idade o consumo de ração apresentou efeito linear e o ganho de peso efeito quadrático. Os pesos relativos da moela e do fígado apresentaram efeito quadrático, e as inclusões de 4,18 e 3,41 gramas/ave proporcionaram os menores pesos respectivamente. A altura das vilosidades do jejuno diminuiu com a suplementação assim como a atividade da lipase pancreática. Conclui-se que a suplementação neonatal beneficiou o desempenho das aves até os 21 dias de idade.

ABSTRACT. The objective was to evaluate the performance, relative organ weight, morphometry, intestinal length and pancreatic enzyme activity of broilers receiving neonatal supplementation. A total of 900 Cobb 500 broiler chicks was housed in 30 boxes of 2.5 m². The treatments were divided in a completely randomized design with six replications, and consisted of five inclusion levels (0.0, 2.5, 5.0, 7.5 and 10 grams per bird). The supplement used was based of amino acids, vitamins and minerals, which was provided on the ration on the first day in the housing. Statistical analysis was performed using SAS (2008) and when significant broken down using a polynomial regression. Due to the inclusion of the neonatal supplement in the period from one to seven and one to 21 days of age, the feed intake presented a linear effect and the weight gain, a quadratic effect. The relative weights of the gizzard and liver showed a quadratic effect, and the inclusions of 4.18 and 3.41 grams/bird provided the lowest weights, respectively. The jejunum villi height decreased with supplementation as well as the activity of pancreatic lipase. It can be concluded that neonatal supplementation benefited the performance of birds up to 21 days of age.

RESUMO Objetivo: Avaliar o consumo de alimentos ultraprocessados e de bebidas açucaradas entre indivíduos vegetarianos e identificar sua associação com o excesso de peso. Métodos: Estudo transversal com método amostral por conveniência, sendo os dados coletados por meio de questionário virtual entre 24/8/2015 e 8/10/2015. A amostra foi composta por indivíduos vegetarianos de ambos os sexos com idade >16 anos. Estudou-se a frequência de consumo de alimentos ultraprocessados e bebidas açucaradas, avaliados por meio de questionário de frequência alimentar, sendo categorizados em função do consumo semanal e diário e do tipo de prática vegetariana. A associação entre excesso de peso e consumo excessivo de alimentos ultraprocessados foi realizada por meio de regressão logística múltipla (RC [IC95%]). Resultados: Participaram desta pesquisa 503 indivíduos (29,8±8,5 anos), com predominância do sexo feminino (83,7%). As principais práticas vegetarianas observadas foram a ovolactovegetariana (45,5%) e a vegana (41,7%), sendo a mediana de tempo de adesão ao vegetarianismo de 5,3 anos. Observou-se que o consumo de bebidas açucaradas (≥2x/dia) e alimentos ultraprocessados (≥3x/dia) foi, respectivamente, 21,0% e 16,0%; em relação aos outros grupos, os veganos apresentaram consumo inferior de alimentos ultraprocessados e bebidas açucaradas. No modelo múltiplo, identificou-se que consumo ≥3x/dia de alimentos ultraprocessados (2,33 [1,36-4,03]), sexo masculino (1,73 [1,01-2,96]), idade ≥35 anos (2,03 [1,23-3,36]) e não preparar as refeições em casa (1,67 [0,95-2,94]) se associaram independentemente com excesso de peso. Conclusão: Embora o vegetarianismo seja frequentemente associado à alimentação saudável e, consequentemente, à pre-venção de desfechos desfavoráveis a saúde, este estudo identificou frequência elevada do consumo diário excessivo de bebidas açucaradas e alimentos ultraprocessados e que este padrão de consumo se associou ao excesso de peso.

ABSTRACT Objective: To assess the consumption of ultra-processed food and sugar-sweetened beverages and to identify the association of this consumption with overweight among vegetarians. Methods: A cross-sectional study with a convenience sampling method was conducted. Data were collected using an online questionnaire from 8/24/2015 to 10/8/2015. Subjects were male and female vegetarians aged >16 years. Using a food frequency questionnaire, we assessed the weekly consumption of ultra-processed food and sugar-sweetened beverages and described the frequency of daily consumption overall and according to type of vegetarianism. The association between overweight and excessive daily intake of ultra-processed food was analyzed by multiple logistic regression (OR [95CI%]). Results: Information was retrieved from 503 individuals (29.8±8.5 years old); 83.7% were women. The most frequent types of vegetarianism in our sample were ovo-lacto (45.5%) and vegan (41.7%), and the median time of vegetarianism was 5.3 years. The consumption of sugar-sweetened beverages (≥2x/day) and ultra-processed food (≥3x/day) was 21.0% and 16.0%, respectively, and regarding the different vegetarianism types, vegans showed the lowest frequency of excessive daily sugar-sweetened beverages and ultra-processed food consumption. In the multivariable analysis, consumption of ultra-processed food ≥3x/day (2.33 [1.36-4.03]), male sex (1.73 [1.01-2.96]), age ≥35 years (2.03 [1.23-3.36]) and not preparing one’s food (1.67 [0.95-2.94]) were independently associated with overweight. Conclusion: Although vegetarianism is frequently associated with a healthier diet and, consequently, prevention of poor health outcomes, this study found that the excessive consumption of sugar-sweetened beverages and ultra-processed food was associated with overweight.

The objective of this study was to evaluate the physicochemical and microbiological parameters of pork meat submitted to dry salting. Sodium chloride (NaCl) was added at levels of 0%, 2.5%, 5%, 7.5% or 10% by the meat weight. Dry salting technique was used, which consists of rubbing the sodium chloride manually, followed by a rest period. The data were submitted to analysis of variance using a completely randomized experimental design. The means were compared by Duncan test at 5%. The salting process reduced (P < 0.05) humidity and water activity, and it increased (P < 0.05) ash, chloride, palmitic acid, and water holding capacity levels compared to those of the control. Luminosity (L*) was lower (P < 0.05) in the control, and a* color was more intense in samples with 2.5% NaCl. Cooking loss was lower (P < 0.05) in the samples salted with 5% and 10% NaCl, and similarity was observed between the levels 0 and 7.5% salt. The treatments with levels 0% and 2.5% NaCl had higher mesophilic counts. The other microbiological parameters were within limits established by law. Therefore, salting with 5% NaCl can be used in pork meat in order to maintain the physicochemical and microbiological characteristics of the final product.
