ExigĂȘncia nutricional de lisina digestĂvel para galinhas poedeiras no perĂodo de 34 a 50 semanas de idade Nutritional requirement of lysine for laying hens in the period from 34 to 50 weeks old
Com o objetivo de estabelecer a exigĂȘncia nutricional em lisina para galinhas poedeiras leves e semipesadas, no perĂodo de 34 a 50 semanas de idade, 360 poedeiras (metade Lohmann e metade poedeiras Lohmann Brown) foram submetidas Ă ração basal contendo 2.850 kcal EM/kg, 15,0% PB, suplementada com cinco nĂveis (0,00; 0,05; 0,10; 0,15 e 0,20%) de L-lisina, de modo a proporcionar 0,584; 0,634; 0,684; 0,734 e 0,784% de lisina digestĂvel nas raçÔes. Foi utilizado esquema fatorial 5 x 2 (nĂvel de lisina e linhagem de aves), com seis repetiçÔes por tratamento e seis aves por unidade experimental, em um delineamento inteiramente casualizado. Foram avaliados a produção de ovos (%), a massa e o peso mĂ©dio dos ovos (g), o consumo de ração (g/ave.dia), a conversĂŁo alimentar (kg ração/dĂșzia ovos), a mudança de peso corporal (g) e a qualidade interna dos ovos (unidade Haugh e Ăndice de albĂșmen e gema). Os nĂveis de lisina nĂŁo influenciaram a mudança de peso corporal, o consumo de ração e a qualidade interna dos ovos em ambas as linhagens. A conversĂŁo alimentar e a produção de ovos, o peso mĂ©dio e a massa dos ovos foram influenciados positivamente pelos nĂveis de lisina, em poedeiras leves e semipesadas. A exigĂȘncia em lisina digestĂvel, estimada pelo modelo quadrĂĄtico, para as aves leves e semipesadas, foi de 0,732 e 0,715% na ração, que corresponde ao consumo diĂĄrio por ave de 893 e 804 mg lisina/ave.dia, respectivamente.<br>With the objective to establish the nutritional requirement of lysine for light and semi-heavy laying hens, in the period from 34 to 50 weeks old, 360 laying hens (half Lohmann and half Lohmann Brown) were submitted to a basal ration containing 2.850 kcal ME/kg, 15.0% CP, supplemented with five levels (0.00, 0.05, 0.10, 0.15 and 0.20%) of L-lysine, to provide 0.584, 0.634, 0.684, 0.734, and 0.784% of digestible lysine in the rations. A 5 x 2 (lysine level and laying hen strain) factorial arrangement, with six replications per treatment and six hens per experimental unit in a completely randomized design was used. Egg production (%), egg mass and average egg weight (g), feed intake (g/hen.day), feed conversion (kg feed /egg dozen), body weight change (g) and internal egg quality (Haugh unit, albumen and yolk index) were evaluated. The lysine levels did not affect the body weight change, feed intake and egg quality in both laying hen strains. Feed conversion and egg production, average egg weight and egg mass were positive influenced by the lysine level, in light and the semi-heavy. The digestible lysine requirement estimated by quadratic model, for the light and the semi-heavy laying hens, was 0.732 and 0.715% in the ration, corresponding to the daily intake per hen of 893 and 804 mg lysine/day, respectively

A pluralistic framework for counselling and psychotherapy: Implications for research.
Historically, training, research and practice in counselling and psychotherapy have been dominated by unitary theoretical models. Although integrative and eclectic positions have been developed as alternatives, these have not been successful in generating research and have resulted in a further proliferation of competing models. In this paper we introduce a 'pluralistic' framework for counselling and psychotherapy and discuss the implications of this framework for research. The basic principle of this pluralistic framework is that psychological difficulties may have multiple causes and that there is unlikely to be one, 'right' therapeutic method that will be appropriate in all situations - different people are helped by different processes at different times. This pluralistic framework operates as a meta-theory within which it is possible to utilise concepts, strategies and specific interventions from a range of therapeutic orientations. The framework is structured around three domains - goals, task and methods - by which therapeutic processes can be conceptualised, critically examined and empirically investigated. These domains, and the relationships between them, are outlined and the collaborative relationship at the heart of the pluralistic framework is discussed. The pluralistic framework provides a means for empirical research directly to inform practice and potential lines of empirical inquiry are outlined, along with findings from a recent study of counselling in schools
Social inequalities in health related behaviours in Barcelona
OBJECTIVEâThis study describes social class inequalities in health related behaviours (tobacco and alcohol consumption, physical activity) among a sample of general population over 14 years old in Barcelona.âšDESIGNâCross sectional study (Barcelona Health Interview Survey).âšSETTINGâBarcelona city (Spain).âšPARTICIPANTSâA representative stratified sample of the non-institutionalised population resident in Barcelona was obtained. This study refers to the 4171 respondents aged over 14.âšDATAâSocial class was obtained from a Spanish adaptation of the British Registrar General classification. In addition, sociodemographic variables such as family structure and employment status were used. As health related behaviours tobacco consumption, alcohol consumption, usual physical activity and leisure time physical activity were analysed. Age adjusted percentages were compared by social class. Multivariate analysis was performed using logistic regression models.âšMAIN RESULTSâWomen in the upper social classes were more likely to smoke, the adjusted odds ratio (OR) for social class V in reference to social class I was 0.36 (95% confidence intervals (95%CI): 0.19, 0.67), while the opposite occurred among men although it was not statistically significant in multivariate analysis. Smoking cessation was more likely among men in the higher classes (OR for class V 0.41, 95%CI: 0.18, 0.90). Excessive alcohol consumption among men showed no differences between classes, while among women it was greater in the upper classes. Engaging in usual physical activity classified as "light or none" in men decreased with lowering social class (OR class IVa: 0.55 and OR class IVb: 0.47). Women of social classes IV and V were less likely to have two or more health risk behaviours (OR for class V 0.33, 95% CI: 0.18, 0.62).âšCONCLUSIONâHealth damaging behaviours are differentially distributed among social classes in Barcelona. Health policies should take into account these inequalities.âšâšâšKeywords: health related behaviours; social class; health surve
