Abstract: an experiment was carried out to evaluate the performance and nutrients digestibility by broiler chickens in the period of 1 to 21 days of age. the experimental design was completely randomized, where t1 was the control treatment constituted by 21.1% of crude protein (cp), 3000 kcal of apparent metabolizable energy (amen)/kg, 0.46% of available phosphorus (ap) and 1.0% of calcium (ca). t2 was the diet with 17.0% of cp and 3000 kcal of amen/kg, t3 the diet with 19.0% of cp and 2900 kcal of amen/kg, t4 the diet with 19.0% of cp and 3000 kcal of amen/kg, and t5 the diet with 19.0% of cp and 3100 kcal of amen/kg. except for the control diet, the diets were formulated with 0.34% of ap, 0.80% of ca and supplemented with phytase. the weight gains of the chickens were similar (p>0.05), independently of the experimental diets. however, the worst feed conversion was observed for the birds fed with 17.0% of cp. the birds which were fed diets with 19.0% of cp and 3000 or 3100 kcal of amen/kg showed performance similar to those fed with the control diet. the excretion of n and p reduced, on average, 16.5% and 22.0%, respectively, and there was increase in the p retention for the birds that were fed the experimental rations. the retention of ca and n was smaller and similar, respectively, for the birds that consumed experimental rations. from these results, it is concluded that the diet with 19.0% of cp and 3000 kcal of amen/kg, supplemented with phytase, does not affect the 1-to-21-day-old broiler chickens and enables to decrease the environmental impact of the nutrients.

Abstract: one hundred cobb male broiler chickens with 42 days old were used to study the effect of different digestible lysine and crude proteins ratios on chemical composition and physical composition of the breast muscle meat. a completely randomized design and two hierarquic criteries of classification was used. the birds were raised and fed a basal diet until 21 days old and, from 22 to 42 days, they were fed a diet formulated with two crude protein (cp) levels (17.0 and 19.5%) and five digestible lysine and cp ratios, 5.9, 6.4, 6.9, 7.4 and 7.9% for ration with 17.0% cp and 5.3, 5.7, 6.1, 6.5, and 6.9% for ration with 19.5% cp, totaling 10 treatments with six replications. at 42 age days, two birds of each replicate were slaughtered for breast muscle meat sample collections. no effects were observed on breast muscle meat for the physical characteristics. in the chemical characteristics, effect in the 19.5% cp level was observed, in a way that the protein of the breast meat meat llinearly increased as the digestible lysine and cp ratio increases, not being evidenced differences for the others evaluated characteristic. the best ratio for protein deposition in the breast muscle meat in the 17.0% cp level was 5.9% (1.34% digestible lysine), and the worse in the 19.5% cp level was 5.3% (1.03% digestible lysine). however, as the others characteristic was not affected, the option to increase the digestible lysine content to improve the breast muscle meat protein deposition will depend on the cost of this operation. the protein level in the diet of broiler chickens in growth phase can be reduced up to 17.0% cp, with no effect on breast muscle meat quality of broiler chickens, by using an ideal protein concept.

Abstract: Objetivou-se avaliar os níveis de inclus o da torta de baba u (0, 4, 8 e 12%) na alimenta o de frangos de corte no período de um a 21 dias de idade. Utilizou-se 200 pintos de corte da linhagem Hubbard, distribuídos em um delineamento experimental inteiramente casualizado, com quatro tratamentos e cinco repeti es de 10 aves por unidade experimental. Os tratamentos consistiram de ra es experimentais que continham níveis crescentes de inclus o da torta de baba u (0, 4, 8, 12%), formuladas para serem isoenergéticas e isoprotéicas. As variáveis de desempenho avaliadas foram o consumo de ra o, ganho de peso e convers o alimentar. Para a determina o de energia metabolizável aparente corrigida, reten o diária de energia, matéria seca e nitrogênio das ra es experimentais realizou-se coleta de excretas de cada repeti o por três dias consecutivos, e estas foram analisadas juntamente com as ra es quanto ao teor de matéria seca, energia bruta e nitrogênio. A inclus o da torta de baba u n o afetou nenhuma das variáveis de desempenho avaliadas. Da mesma forma n o foi observado efeito dos níveis de inclus o da torta de baba u sobre a energia metabolizável corrigida e sobre o coeficiente de reten o de energia bruta. Concluiu-se que a torta de baba u pode ser utilizada como ingrediente em ra es de frangos de corte de um a 21 dias até o nível de 12%. The objective of this study was to evaluate the levels of inclusion of babassu coconut (0, 4, 8 and 12%) in diets for broiler chickens from 1 to 21 days old. 200 Hubbard chicks were distributed in a completely randomized design with four treatments and five replications, being each experimental unit composed of 10 birds. The treatments consisted in experimental diets containing increasing levels of inclusion of babassu coconut (0, 4, 8 and 12%), formulated to contain the same nutritional level. The performance of variables evaluated were feed intake, weight gain and feed conversion. The apparent metabolizable energy, diary retention of gross energy, dry matter and nitrogen of experimental diets was determined by total collection of excreta for three consecutive days, which are analyzed together with the feed for dry matter, gross energy and nitrogen contents. The inclusion of the babassu not affected any of the evaluated variables. Likewise, there was no effect of inclusion levels of babassu coconut on the apparent metabolizable energy and the diary of retention of gross energy. On this basis, the babassu coconut can be used as an ingredient in diets of broilers from 1 to 21 days until the level of 12%.

Abstract:

Background: Adolescents who rely on social aid networks tend to be more socially competent and enjoy higher levels of quality of life than those who interact only with their own limited groups of family and friends. In this light, the present study aimed to measure social capital and analyse its possible relation to adolescents’ quality of life. Methods: This is a cross-sectional analytical study with 363 adolescents from the Brazilian NGO. The instruments used included a short Portuguese version of the Integrated Questionnaire to Measure Social Capital (SC-QI) from the World Bank and its abbreviated Portuguese version from the World Health Organization Quality of Life Bref (WHOQoL-Bref) used to measure the quality of life. To measure social capital, the present study chose to use a segmentation analysis, along with the Two-Step Cluster method, applying Euclidian distance and the criteria of centroid aggregation. The Mann-Whitney test was used to compare the scores of WHOQoL-Bref domains among the clusters, at a significance level of 5%. Results: The segmentation analysis resulted in two clusters, with 160 (44.1%) adolescents classified as Low Social Capital (LSC) and 178 (49%) classified as High Social Capital (HSC). Participation in activities for the good of the community (p < 0.001), opinion regarding the differences between people in the community (p = 0.002), and number of community meetings (p < 0.001) constituted the decisive variables for determining the separation of the clusters. When quality of life among the newly formed clusters was compared, the highest average score in the HSC cluster was found in the Psychological Domain (75.4 ± 11.9), whereas in the LSC cluster, the highest average score was found in the Physical Domain (74.6 ± 12.6). Lower quality of life scores was found in the environmental domain for both the LSC clusters (51.3 ± 14.0) and the HSC clusters (54.7 ± 15.5). This difference proved to be statistically significant (p = 0.009). Conclusions: The results showed that adolescents with higher social capital also presented higher
