Abstract This study assessed the effect of different periods of post-hatch fasting on animal performance and breast and digestive system growth in European quail. Quail chicks were distributed in a completely randomized design, with four fasting periods (0, 24, 36, and 48 hs) and four replications of 40 birds per treatment. In 1 to 14-day-old chicks, weight gain decreased with increasing fasting time. Compensatory gain was observed from 15 days of age onward. Fasted quail had a lower length and relative weight of the digestive system than fed animals for up to 14 days. Histologically, the duodenal villus height was significantly lower in 3-day-old quail fasted for 36 hs than in those fasted for 48 hs, but this effect was not observed at 7 days. Scanning electron microscopy showed no differences in the small intestinal mucosa between fasted and fed birds at 3 days of age. Post-hatch fasting reduced the relative weight of the breast in quail aged 1 to 14 days but did not affect type IIa and IIb fiber diameter at 35 days. On the basis of these results, it is recommended that European quail raised for meat should not be fasted for more than 48 hs post-hatch. posthatch post hatch design 0, 0 (0 24 4 treatment 14dayold dayold day old time onward Histologically 3dayold Posthatch Post results posthatch. hatch.

Abstract This study described the growth, morphometric, biomechanical, and chemical properties of the femur, tibiotarsus, and tarsometatarsus of European and Japanese quail. Analyses were performed at 13 and 15 days of incubation, at hatch, and at 4, 7, 10, 14, 21, 28, and 35 days post-hatch (n=6/subspecies/period). Bone specimens were analyzed by cone-beam computed tomography, biomechanical assays, chemical analyses, and histomorphometry. Variables were fitted by the Gompertz function and its derivative or assessed using the analysis of variance. Analysis of the derivative of Gompertz curves showed that the growth behavior of the tarsometatarsal bone was similar between quail subspecies, and the femur and tibiotarsus of European quail increased first in width and then in length, whereas the opposite occurred in Japanese quail. There was an interaction between quail subspecies and days of growth on femoral, tarsometatarsal, and tibiotarsal bone densities. Femoral and tibiotarsal cross-sectional areas were influenced by the interaction of quail subspecies and day of growth. Interaction effects were significant for breaking strength and phosphorus percentage. European and Japanese quail have different femoral and tibiotarsal growth patterns, especially in the first few days after hatching, whereas tarsometatarsal growth is similar between subspecies. morphometric 1 incubation hatch 4 7 10 14 21 28 3 posthatch post n=6/subspecies/period. n6subspeciesperiod nsubspeciesperiod n=6/subspecies/period . n 6 period (n=6/subspecies/period) conebeam cone beam tomography assays analyses histomorphometry variance length densities crosssectional cross sectional percentage patterns hatching 2 subspeciesperiod (n=6/subspecies/period

Abstract Growth curves have been described in the quail but with no attention to the muscle composing of the breast. The description of the characteristics of growth curves to body weight and to breast muscle was the aim of this study. Morphological development of Musculus supracoracoideus and Musculus pectoralis in European and Japanese quail was assessed from the final incubation of to 35 days. Gompertz models were adjusted with maximum growth rates to body weight, breast weight, and Musculus pectoralis and supracoracoideus weight at 17.6; 22.2; 23.5, and 21.4 days. The European quail had a higher body and breast weight at maturity. Musculus supracoracoideus developed faster in both subspecies but with larger Musculus pectoralis. Both musculus had a greater number of fibers type IIA and largest fibers IIB, with quadratically increasing in fiber diameter with age in both subspecies and muscles. At 35 days, results of meat quality indicated similarity between genders and subspecies, with darker and redness breast meat in Japanese quail. In conclusion, breast weight gain was a result of type IIA and IIB fiber hypertrophy in both muscles and, despite the difference in size and aptitude, Japanese and European quail showed similar body and muscle growth patterns. study 3 days 17.6 176 17 6 22.2 222 22 2 235 23 5 23.5 214 21 4 21. maturity conclusion aptitude patterns 17. 1 22. 23.

A otospongiose é uma osteodistrofia focal primária da cápsula ótica que acomete indivíduos geneticamente predispostos e promove perda auditiva progressiva. OBJETIVO: Verificar a aplicabilidade da avaliação audiométrica no tratamento medicamentoso da otospongiose. MATERIAL E MÉTODO: Estudo prospectivo, randomizado, controlado, duplo-cego, envolvendo 26 pacientes com diagnóstico clínico, audiométrico e tomográfico de otospongiose. Os pacientes elegíveis para o estudo foram alocados em três grupos (A, B e C) e receberam o tratamento com alendronato de sódio (B), fluoreto de sódio (C) e placebo (A) por 6 meses. Após este período, os mesmos realizaram nova avaliação audiométrica. RESULTADOS: Na análise das diferenças entre as vias aérea e óssea (gap), não houve diferença estatisticamente significante. Também não foram encontradas diferenças em relação ao limiar de reconhecimento da fala (SRT) e a discriminação vocal (IRF) entre os períodos pré e pós-tratamento. CONCLUSÃO: Após seis meses de tratamento medicamentoso, a avaliação audiométrica evidenciou manutenção dos limiares auditivos, sugerindo estabilização da atividade da lesão otospongiótica.

Otospongiosis is a primary osteodystrophy of the otic capsule that affects genetically predisposed individuals and leads to a progressive hearing loss. AIM: To evaluate the applicability of audiometric evaluation during drug treatment for otospongiosis. MATERIALS AND METHODS: A prospective, randomized, controlled, double-blind study involving 26 patients with clinical, audiometric and CT scan image of otosclerosis. Patients eligible for the study were divided into three groups (A, B and C) and received treatment with alendronate sodium (B), sodium fluoride (C) and placebo (A) for 6 months. After this period they were submitted to new tests. RESULTS: There were not statistically significant differences between air and bone conduction (gap). We also found no differences in the speech recognition threshold (SRT) and speech discrimination (IRF) between before and after treatment. CONCLUSION: After six months of drug treatment the audiometric evaluation kept the same hearing thresholds, suggesting stabilization of the otospongiotic lesions.
