[Translated article] Translation, validation, and cultural adaptation of the HSS-ES scale (Hospital for Special Surgery's [HSS] Shoulder Surgery Expectations Survey).

INTRODUCTION: The questionnaire Hospital for Special Surgery Shoulder Surgery Expectations Survey (HSS-ES) is a tool used to assess the preoperative expectations of patients with shoulder pathologies. The purpose of this study is to translate, culturally adapt, and validate the Spanish version of the HSS-ES questionnaire to assess preoperative expectations in Spanish-speaking patients. METHODOLOGY: Questionnaire validation study, using a structured method where a survey-type tool was processed, evaluated and validated. The study involved 70 patients from the shoulder surgery outpatient clinic of a tertiary care hospital, with shoulder pathologies requiring surgery. RESULTS: The version of the questionnaire translated into Spanish presented a very good internal consistency with a Cronbach's Alpha of 0.94 and a very good reproducibility with an Intraclass Correlation Coefficient (ICC) of 0.99. CONCLUSION: The HSS-ES questionnaire presents an adequate intragroup validation and a strong intergroup correlation according to the internal consistency analysis of the questionnaire and the ICC. Therefore, it is considered an adequate questionnaire to use in the Spanish-speaking population.

Observational study on the breeding performance of emus (Dromaius novaehollandiae) in Brazil / [Estudo observacional sobre o desempenho reprodutivo de emus (Dromaius novaehollandiae) no Brasil]

The objective of this study was to describe emus' breeding performance in Brazil at different ages, grouped in couples or colonies. The duration of the breeding season and the production of eggs per female housed were recorded, and the productivity and breeding variables were associated with the variation of the photoperiod. The total production of the flock was 180 eggs, and the breeding season lasted 167 days (April-September), a period with an average of 11 h and 11min of daylight. The breeding season lasted 113, 133 and 82 days, the numbers of eggs produced per female were 7.29, 25.67 and 17.3, and productivity values were 31.6, 38.6, and 45.4% in the groups of birds with ages of two, four and seven years, respectively. The breeding season in 2016 occurred between April and August in Brazil. Older birds tended to start breeding later. The production rate observations indicated that earlier peak production was associated with lower egg production potential. Finally, there was a tendency for better breeding performance of birds housed in couples than in groups with more birds.(AU)

O objetivo deste estudo foi descrever o desempenho reprodutivo de emus de diferentes idades, agrupados em casais ou em colônias, no Brasil. A duração da estação reprodutiva e a produção de ovos por fêmea alojada foram registradas, a produtividade e as variáveis reprodutivas foram associadas às variações no fotoperíodo. A produção total do lote de aves foi de 180 ovos, e a estação reprodutiva durou 167 dias (abril-setembro), período que apresentou fotoperíodo médio de 11 horas e 11 minutos. Nos grupos de aves de dois, quatro e sete anos de idade, a estação reprodutiva durou 113,, 133 e 82 dias, o número de ovos por fêmea foi de 7,29, 25,67 e 17,3 e a produtividade foi de 31,6, 38,6 e 45,4%, respectivamente. A estação reprodutiva em 2016 ocorreu entre abril e agosto no Brasil. Aves mais velhas tenderam a iniciar o período reprodutivo mais tarde. As observações na taxa de produção podem indicar que quanto mais precoce o pico produtivo, menor o potencial de produção de ovos em emus. Houve a tendência ao melhor desempenho reprodutivo das aves alojadas em casais em comparação com as alojadas em colônias.(AU)

Influência do sistema de criação em piso sobre cama e gaiola sobre as características ósseas e a qualidade físico-química e microbiológica de ovos de galinhas / Influence of the floor and cage creation system on the bony characteristics and the physical-chemical and microbiological quality of hen eggs

O experimento foi realizado no setor de avicultura/UFRRJ, utilizando 348 galinhas semipesadas (linhagem Dekalb Brown), com 52 semanas de idade, criadas sob dois sistemas de produção: cage-free e em gaiolas. Os dados obtidos pela análise físico-química e microbiológica dos ovos e a resistência óssea à quebra foram submetidos à análise de variância. No caso de ocorrerem efeitos dos diferentes sistemas de produção, foi aplicado o teste de Tukey a 5% de probabilidade para comparação das médias. A qualidade físico-química foi igualmente favorecida pelos dois sistemas de produção, indicando que as circunstâncias experimentais propiciaram condições adequadas para a formação de ovos de boa qualidade. O sistema de gaiola não desfavoreceu as características ósseas das galinhas, apontando que, em densidades adequadas, a gaiola pode não exercer um fator prejudicial para a qualidade óssea. O sistema de produção cage-free piorou a contaminação da casca, comprovando que ovos postos em ninhos são mais contaminados em comparação aos produzidos em gaiolas.(AU)

The experiment was carried out in the poultry sector / UFRRJ, using 348 semi-heavy hens (Dekalb Brown line), 52 weeks old, raised under two cage-free production systems and cages. The data obtained by the physical-chemical and microbiological analysis of the eggs and the bone resistance to the break were submitted to analysis of variance, in case of effects of the different production systems, the Tukey's test was applied at 5% of probability for comparison of the means. The physical-chemical quality was also favored by the two production systems, indicating that the experimental circumstances provided adequate conditions for the formation of good quality eggs. The cage system did not disfavor the bony characteristics of the hens, indicating that at suitable densities, the cage may not exert a detrimental factor to bone quality. The cage-free production system worsened shell contamination by proving that nesting eggs are more contaminated compared to those produced in cages.(AU)

Efeito de diferentes aditivos zootécnicos sobre a qualidade de ovos em duas fases produtivas da codorna / Effect of different zootechnical additives on egg quality in two quail production phases

Com o objetivo de avaliar a qualidade dos ovos de codornas alimentadas com diferentes aditivos em duas fases de produção, 360 codornas foram distribuídas em um delineamento inteiramente ao acaso, em esquema de parcela subdividida no tempo (de nove até 23 e de 24 até 39 semanas de idade), com cinco tratamentos e oito repetições de nove aves cada, organizados da seguinte forma: controle, antibiótico, prebiótico, probiótico e simbiótico. As variáveis analisadas foram: unidade Haugh, índice de gema, porcentagem dos componentes do ovo, espessura de casca medida pelo micrômetro e pelo MEV. O fornecimento dos aditivos no segundo período aumentou a unidade Haugh e nos dois períodos avaliados proporcionou aumento da porcentagem de gema e de casca e da espessura da casca e de suas membranas. A inclusão dos aditivos foi mais eficiente em aumentar o peso dos ovos e a porcentagem de gema e de casca no segundo período. A espessura da casca (MEV) melhorou após inclusão de antibiótico e simbiótico na ração no segundo período. A inclusão de aditivos na ração melhora a qualidade dos ovos de codornas durante toda a fase produtiva. Antibiótico e simbiótico são mais eficazes em melhorar a espessura da casca dos ovos produzidos durante o segundo período produtivo.(AU)

To evaluate the quality of eggs of quails fed with different additives in two stages of the productive period, 360 quails were distributed in a completely randomized design in a split plot scheme in time (9 to 23 and 24 to 39 weeks of age) with five treatments and eight repetitions of nine birds each, organized as follows: control, antibiotic, prebiotic, probiotic, and symbiotic. The analyzed variables were: Haugh unit, yolk index, percentage of egg components, shell thickness measured by the micrometer and the SEM. The supply of additives in the second period increased Haugh units, and in both periods provided an increase in the percentage of yolk and shell and improved the thickness of the shell and its membranes. The inclusion of additives was more effective in promoting weight gain in eggs and the percentage of egg yolk and egg shell from 24 to 39 weeks of age. The shell thickness (SEM) improved after inclusion of antibiotic and symbiotic in feed in the second period. The addition of additives in food improved the quality of Japanese quail egg throughout the productive period. Antibiotics and symbiotics proved to be more effective in improving shell thickness of the eggs produced in the second productive period.(AU)
