USE OF VIRGINIAMYCIN AND SALINOMYCIN IN THE DIET OF BEEF CATTLE REARED UNDER GRAZING DURING THE RAINY SEASON: PERFORMANCE AND RUMINAL METABOLISM

The rumen is the most studied organ with regard to the symbiotic interaction between host and microbiota in the digestive tract of ruminants. Thus, this study aimed at evaluating the effects of including virginiamycin and salinomycin to the supplement for cattle fed tropical grass diet during the rainy season. Three treatments were set: control - mineral supplement COMIGO - Cria 61-F2 (MS); virginiamycin - MS + virginiamycin (Phigrow (r)) 100 mg/animal/day; salinomycin - MS + salinomycin (Posistac(r)) 108 mg/animal/day for the experiment 1 (performance) and experiment 2 (ruminal metabolism). The control showed higher Mineral supplement intake (MSI) (P 0.05) and better financial efficiency. Biometric measurements showed no differences (P> 0.05), suggesting a change in the ADG composition. There was no difference (P> 0.05) for dry matter digestibility (DMDIS), acid detergent fiber digestibility (ADFDIS), ruminal pH and ammoniacal-N. The virginiamycin had the highest effective neutral detergent fiber (NDF) degradability (P> 0.05) in the passage rates of 2 and 5%; the degradability rates were similar to control treatement and higher than that of salinomycin at the rate of 8%/hour. The virginiamycin or salinomycin can be conveyed to the MS, but do not promote significant effects on ruminal pH, ammoniacal-N, DMDIS and ADFDIS; but virginiamycin promoted greater effective degradability of NDF. Keywords: ammoniacal-N; antimicrobials; degradability; growth; ruminal pH

Métodos de análise de dados longitudinais para o melhoramento genético da pinha

The objective of this work was to compare the ways of analyzing repeated measures to improve the production of sugar apple (Annona squamosa). Twenty half‑sib progenies were evaluated, over three years (2003, 2004 and 2005), in a randomized block design with five replicates, and each plot was constituted of four plants. The evaluated trait was the number of fruit per individual. The models of compound symmetry, autoregressive with heterogeneous variance, the structured ante‑dependence, and compound symmetry with heterogeneous variance were analyzed using the ASReml software. The estimation of variance components and the prediction of breeding values were made by the REML/BLUP. The comparison of the models was done by the likelihood ratio test and Akaike’s information criterion. The structured ante‑dependence model, for the factors progeny and parcel, and the multivariate model, for the residual factor, are the best approaches for data analysis, providing efficiency and parsimony over the full multivariate model. With the structured ante‑dependence model, it is possible to identify superior families in each harvest, and also the families with larger total number of fruit.O objetivo deste trabalho foi comparar formas de análise de medidas repetidas para o melhoramento da produção de frutos de pinha (Annona squamosa). Vinte progênies de meias-irmãs foram avaliadas por três anos (2003, 2004 e 2005) em delineamento de blocos ao acaso, com cinco repetições, com cada parcela constituída de quatro plantas. A característica avaliada foi o número de frutos por indivíduo. Os modelos de simetria composta, de simetria composta com variâncias heterogêneas, autorregressivo com variâncias heterogêneas, e antedependência estruturada, foram analisados com o programa ASReml. A estimação dos componentes de variância e a predição dos valores genéticos foram feitas com o procedimento REML/BLUP. A comparação dos modelos foi realizada pelo teste de razão de verossimilhança e pelo critério de Akaike. O modelo antedependência estruturada, para os fatores progênie e parcela, e o modelo multivariado, para o fator resíduo, são as melhores abordagens para a análise dos dados, pois propiciam eficiência e parcimônia em relação ao modelo multivariado completo. Com o modelo antedependência estruturada, é possível a identificação de famílias superiores, em cada colheita, e também de famílias com maior número total de frutos

Use of a flap based on the superior lateral genicular artery to cover lower limb injuries: case reports

The knee is one of the main joints in the human body, and due to its conformation and functionality, it is easily susceptible to injuries. Surgical reconstruction of injuries around the knee and proximal region of the leg represents a major challenge due to the exposure of osteoarticular, tendinomuscular and neurovascular structures and has been performed using various muscle and musculocutaneous flaps. Other flaps are also described for treating these lesions, although less frequently in the literature, such as the cutaneous flap based on the pedicle of the superior lateral genicular artery. Next, It presents a report of five cases of patients who were victims of motorcycle accidents in which the lesion was covered around the knee and proximal region of the leg using a skin flap based on the pedicle of the superior lateral genicular artery, in which good coverage of lesions, high flap survival rate, good clinical and aesthetic results. The use of the superior lateral genicular artery presents aesthetic advantages since the color and texture of the flap are similar to those of the knee region and provide a better quality appearance, in addition to not causing joint mobility problems

Processo de validação de instrumento que permite avaliar o pensamento tático de crianças

The goal: validate an instrument that can measure the tactical thinking of the children when in passing, in-game engines invasion. Methods: The validation of the test, five experts trained in physical education and sports specialists. He headed the evaluation of these experts, 15 photographs. In order to achieve validation of the instrument were adopted the concordance index> 0.8 among experts about the test items. Results: Ten photographs showed concordance index >0.8. Conclusion: Unable to verify and record that the instrument can serve the function for which it was drafted.Validar un instrumento que pudiera medir el pensamineto táctico de niños, dentro de situaciones de pase en juegos motores de invasión. Métodos: participaron de la validación del test cinco peritos graduados en Educación Física y expertos en juegos deportivos. Se les envió a los peritos, para evaluación, 15 fotografías. Con el fin de conseguir la validación del instrumento, se adoptó el índice de concordancia > 0,8 entre los peritos sobre los ítems del test. Resultados: cinco fotografías presentaron índice de concordancia < 0,8. De las 10 fotografías validadas, se consiguió estabelecer el solucionario del test y el resultado patrón. Conclusión: se consiguió verificar que el instrumento atiende a la función para la que se ha elaborado.RESUMOObjetivo principal: validar um instrumento que consiga mensurar o pensamento tático das crianças quando em situação de passe, nos jogos motores de invasão.
