Promoção da saúde mental na escola: diga não ao cyberbullying

A adolescência é a etapa da vida compreendida entre a infância e a fase adulta, marcada por complexo processo de crescimento e desenvolvimento biopsicossocial. Objetivou-se descrever a experiência vivida com adolescentes, que teve como fito promover ações de saúde mental no contexto escolar, tendo como foco os efeitos nocivos do cyberbullying. Trata-se de relato de experiência, referente ao projeto "Promoção da Saúde Mental na Escola: diga não ao cyberbullying”, desenvolvido por quatro estudantes de Enfermagem, com alunos do ensino médio do município de Sobral-CE, Brasil. Realizaram-se três encontros. A cada encontro, procederam-se a ações de promoção à saúde mental, as quais foram baseadas na metodologia de Jean Piaget, que buscou estimular o senso crítico e reflexivo dos adolescentes, a partir de questionamentos referentes às diversas situações vivenciadas. Assim, por meio de folders educativos, aplicativos digitais (HelpTeen), slides, músicas animadas e dinâmicas de interação, estimulou-se a participação dos alunos para o envolvimento com a temática abordada. As ações desenvolvidas com os adolescentes propiciaram educação em saúde, além do aprimoramento e amadurecimento intelectual. A experiência oferecida pelo módulo Vivências de Extensão I – Juventudes foi fundamental para que as acadêmicas envolvidas pudessem atuar como protagonistas do processo de educação em saúde, capacitando-as para lidarem com demandas e imprevistos a serem vivenciados como futuras profissionais da saúde, além de contribuir com a promoção da qualidade de vida dos jovens com os quais se desenvolveu o projeto de extensão

Digestible tryptophan requirements of meat quails in the growth phase

The objective of this experiment was to estimate the digestible tryptophan (DTrp) requirements for growing meat quails. In the first experiment (1-14 days of age), 1,950 quails were distributed in a completely randomized design, with six levels of DTrp (0.27; 0.30; 0.33; 0.36; 0.39 and 0.42% of diet), five replications and 65 quails per experimental unit. There was a linear increase of feed intake, tryptophan intake, weight gain and body weight with the DTrp levels increase. In the second experiment (15-35 days of age), 1,350 quails were distributed in a completely randomized design, with six levels of DTrp (0.22; 0.25; 0.28; 0.31; 0.34 and 0.37% of diet), five replications and 45 quails per experimental unit. There was a linear increase for tryptophan intake, carcass yield, ash levels and protein deposition rate with the DTrp levels increase. In the third experiment (28-35 days of age), conducted to determine the nitrogen balance, 150 males were housed in galvanized wire cages featuring drinker, feeder and individual metal tray lined with plastic to collect the excreta. The design was completely randomized, with six levels of DTrp (0.22; 0.25; 0.28; 0.31; 0.34 and 0.37% of diet), five replicates and five quails per experimental unit. Linear decrease was observed on the nitrogen balance and metabolization coefficient with the DTrp levels increase. The nutritional requirement of digestible tryptophan for maximum growing of meat quail, in the period from 1 to 14 days of age, is higher or equal to 0.42%; in the period from 15 to 35 days, it is 0.22%

Semi-purified glycerin in the meat quails feeding

Três experimentos foram conduzidos para determinar o valor nutritivo da glicerina semipurificada (GS) e verificar seu efeito sobre o desempenho, composição química corporal, características de carcaça e a viabilidade econômica de sua utilização em dietas para codornas de corte. No Experimento 1 foram utilizadas 75 codornas, com 22 dias de idade, alojadas em gaiolas de metabolismo, distribuídas em um delineamento inteiramente casualizado (DIC), com 3 tratamentos e 5 repetições, com 5 aves por repetição. Os tratamentos consistiram de uma ração referência (RR) e duas rações teste (RT), sendo que a GS substituiu a RR em níveis de 8 e 12%. O valor estimado de EMAn para a GS foi de 2.476 kcal/kg de matéria natural. No Experimento 2 foram utilizadas 1.320 codornas de corte (55 aves em cada boxe), distribuídas em DIC, com seis tratamentos e quatro repetições. Os tratamentos foram constituídos por seis rações com níveis crescentes (0, 3, 6, 9, 12 e 15%) de GS. Não foram observados efeitos da GS sobre as variáveis de desempenho. O custo por quilograma de peso vivo produzido aumentou linearmente (P<0,05) com a inclusão dos níveis de GS. Considerando os dados de desempenho, conclui-se que a GS pode ser incluída até o nível de 15%, na fase de 1 a 14 dias. No Experimento 3 foram utilizadas 1.032 codornas (43 aves em cada boxe), distribuídas sob as mesmas condições do Experimento 2. A glicerina semipurificada influenciou de forma linear (P<0,05) a umidade da cama e a biomassa corporal acumulada (BCA), e, de forma quadrática a conversão alimentar e a BCA (P<0,05). O custo por quilograma de peso vivo produzido aumentou linearmente (P<0,05) com a inclusão dos níveis de GS. Considerando os dados de desempenho, a GS pode ser incluída até o nível de 10%, na fase de 15 a 35 dias.  Three experiments were conducted to determine the nutritional value of semi-purified glycerin (SG), and its economic feasibility for use in meat quail feed. Its effect on the performance, body chemical composition, and carcass yield were assessed. In experiment 1, 22-day-old quails, were housed in metabolic cages, distributed in a completely randomized design (CRD), with three treatments, five replicates, and five birds per repetition, using 75 quails in total. Treatments consisted of a reference diet (RD) and two test diets (RT) in which 8% and 12% SG replaced the RD. The estimated value of nitrogen-corrected apparent metabolizable energy (AMEn) for SG was 2,476 kcal/kg. In experiment 2, 1320 quails (55 quails in each box) were distributed in a CRD with six treatments and four replicates. The treatments consisted of six diets containing increasing levels (0%, 3%, 6%, 9%, 12%, and 15%) of SG. There were no effects of SG on the performance variables. The cost per kilogram of live weight produced increased linearly (P<0.05) with the percentage of SG in the diet. The performance data suggest that SG may be included in up to 15% of the diet in 1- to 14-day-old quails. In experiment 3, 1032 quail (43 quails in each box) were distributed under the same conditions as in experiment 2. SG was positively associated with (P<0.05) litter moisture and body biomass accumulated (BBA) weight. A quadratic effect on feed conversion and BBA (P<0.05) was observed. The cost per kilogram of live weight produced increased linearly (P<0.05) with the percentage of SG in the diet. Therefore, SG may be used to make-up 10% of the diet of 15–35-day-old quail

Nutritional requirements of digestible threonine for growing meat-type quails

The objective of this study was to estimate the nutrient requirements of digestible threonine for meat-type quails (Coturnix coturnix sp) in the growth phase. A total of 1350 not sexed meat-type quails were distributed in a completely randomized design with six threonine levels (10.80, 11.50, 12.20, 12.90, 13.60 and 14.30 g/kg as fed), five replications and 45 quails per experimental unit, from 1 to 14 days of age. The threonine levels in the diet had a quadratic effect on body weight, feed intake and weight gain. Estimates for highest body weight (79.41 g), feed intake (128.96 g/bird) and weight gain (70.73 g) were observed with diets containing 12.60 g/kg of digestible threonine. According to the LRP model, the threonine intake was estimated at 13.40 g/kg of digestible threonine. Protein deposition rate and energy retained in the carcass showed quadratic effect, with estimated digestible threonine levels of 11.80 and 12.00 g/kg in the diet for maximum protein deposition rate (2.00 g/bird) and retained energy in the carcass (15.88 kcal/g), respectively. There was a linear effect on feed cost per kg of live weight gain as threonine levels were increased. Nutritional requirement of digestible threonine for meat-type quails for maximum growth is 12.60 g/kg, corresponding to a digestible threonine:digestible lysine ratio of 67.02

Estimation of growth parameters of body weight and body nutrient deposition in males and females of meat- and laying-type quail using the Gompertz model

ABSTRACT The objective of this study was to estimate the growth parameters of body weight and body nutrient deposition in males and females of one meat- (Coturnix coturnix coturnix) and two laying-type quail strains (Coturnix coturnix japonica), designated either yellow or red, using the Gompertz model. A total of 1350 quail from 1 to 42 days of age were used and they were distributed in a completely randomized design, with five replications for each strain. The parameters of body weight and body composition of the quail were analyzed weekly and evaluated using the Gompertz equation; growth rates and body nutrient deposition were evaluated through derivative equations. The three strains evaluated showed differences in their potential, growth rates, and body chemical composition. The composition up to 42 days of age was not sufficient to adjust the fat deposition data using Gompertz. Due to the period evaluated, the Gompertz model allowed to verify that females have higher body growth rates when compared with males of the same strains, with accelerated growth up to 14 and 21 days of age for males and females, respectively. Regarding the laying strain, the red has greater growth, with similar potential in depositing protein and water in the carcass, but they are more precocious in the deposition of these nutrients

Comparison of growth curve parameters of organs and body components in meat- (Coturnix coturnix coturnix) and laying-type (Coturnix coturnix japonica) quail show interactions between gender and genotype

The objective of this study was to estimate growth parameters of carcass components (wing, thighs and drumsticks, back and breast) and organs (heart, liver, gizzard and gut) in males and females of one meat-type quail strain (Coturnix coturnix coturnix) and two laying strains (Coturnix coturnix japonica) designated either yellow or red.A total of 1350 quail from 1 to 42d old were distributed in a completely randomised design, with 5 replicates of each strain. The carcass component weights and body organs were analysed weekly and evaluated using the Gompertz function; growth rates were evaluated through derivative equations.The meat-type strain presented the highest growth rates in carcass components and organs. Across strains, females showed the highest weight of internal organs at maturity compared to males.Females had greater growth potential in breast, wings and back than males for both yellow and red laying quail
