Avaliação nutricional do feno das folhas da amoreira (Morus alba L.) em frangos de corte

The trial was carried to evaluate the nutritional effects of mulberry leaf hay in broiler chickens. Five treatments were used: control (no mulberry, 3.16% CF); 15% mulberry (4.14% CF); 30% mulberry (5.09% CF), no mulberry (4.14% CF); no mulberry (5.09% CF). A randomized blocks design was used, with two blocks and three replications into the blocks to evaluate performance index, histopathological examination of the visceral organs and morphometric measurements of the hepatocyte nucleus and pancreatic acini. A poor performance index was observed for broilers feeding on mulberry leaves; lesions such as steatosis, proliferation of hepatic duct cells and multiple necrosis were found in the livers of the chickens fed with 30% mulberry (5.09% CF), as well as size reduction of the hepatocyte nucleus and pancreatic acini. From these data, it is concluded that mulberry probably has some toxic substance which can interfere in the improvement of diet ingredients, resulting in damage to broiler chickens.

Avaliação do desempenho ambiental da produção canavieira com colheita mecanizada: contribuição à implantação de um sistema simplificado de gestão ambiental da propriedade

The consuming of the natural resources in the agricultural sector does not represent only one external factor of the productive process, but also it implies in a bigger cost for the production, justified for this environmental degradation. In view of the necessity of evaluating the sustainment of the agricultural businesses, the use of performance indicators if makes of extreme importance. The measurement of the support through environmentalindicators is one of the most accepted forms of performing the evaluation of one given agricultural activity. In this context, the Base System for Eco-certification of Agricultural Businesses (Eco-cert Rural) developed by the Embrapa Environment at Jaguariúna/SP, has for purpose to present a method of evaluation of the agricultural businesses, not only of the point of view of the ecological performance, as well as considering the social, economic and organizational aspects. Through the analysis of the performance of the activity and the regularization of the disconformities found, it makes possible the eco-certification of the activities in the varied existing protocols, offering technologies designed to the sustainable development of the agricultural businesses. Using Eco-cert.Rural, this work evaluated the contribution of the use of mechanized harvest in sugar cane handling, front to the traditional system of manual harvest, using the fire. In the Sugar Cane Activity General Performance Index, Agrícola Rio Claro scored 2,08 of a maximum of 15. Amongst all the indicators, those wich reached performance worse had been related to the Use of Energy and the Income, by increasing fossil fuel consumptiom, and implying income concentration due to resignations of rural workers. However, the improvements on the environment quality by supressing manual harvest through fire are very significant. Beyond the great reduction in...(Complete abstract click electronic access below)

Desempenho tático de jogadores de futebol: comparação entre equipes vencedoras e perdedoras em jogo reduzido

The aim of study was to verify what tactical behaviors differ winner from loser teams in small sized games in youth soccer players. The tactical performance of winners and losers teams was compared through of System of Tactical Assessment in Soccer (FUT-SAT). Three thousand eight hundred and eight tactical actions were carried out by seventy-two youth soccer players from the under-11 (n=12), under-13 (n=12), under-15 (n=30) and under-17 (n=18) categories of Portuguese teams. Twenty four teams were composed to analyze, each team carried out one match (12 match analyzed). Each team was composed by three line players with goalkeeper which was not analyzed in test. The statistical analysis was performed thought the SPSS 17.0 software for Windows. A descriptive analyze and the KolmogorovSmirnov, Chi-square, Mann-Whitney U and T-Test tests to the independent samples was carried out, and the Cohen’s Kappa test to determining of the sample reability. Considering 76 variables analyzed, 12 presented significant differences among players of winners and loses teams. The players of the winner teams presented superiority in Macro-Category Action, in the Defensive tactical principles, Equilibrium and Defensive Unity. In the category Local of action in the Field, the winner teams presented superiority in the number of defensive actions performed in the defensive midfielder. In the category Result of the action, the variables Keep without the ball, Retrieving the ball possession and Shots on goal the winner teams presented higher results, while in variables Losing the ball possession and Suffering shot on goal the loser teams presented higher results. In the Performance Macro-Category, the superiority of the winners was showed by better Tactical Performance Index (TPI) in the Penetration principles, Offensive Unity, and in the Offensive phase of the game. The results demonstrated that the winner players presented superiority in both stages of the game.

Effects of isoflurane on Tei-index of myocardial performance in healthy dogs

Recently, the Tei-index, a noninvasive index that combines systolic and diastolic time intervals, has been proposed to assess global cardiac performance. However, the effects of isoflurane on the Tei-index have not been characterized. This study aimed at studying the effects of 1.0 minimal alveolar concentration isoflurane anesthesia on the pre-ejection period (PEP), left ventricular ejection time (LVET), PEP/LVET ratio, isovolumic relaxation time (IVRT), stroke index (SI), cardiac index (CI), heart rate (HR), and the Tei-index in healthy unpremedicated dogs. We observed significant increases in PEP, PEP/LVET ratio, IVRT, and TEI, whose maximal increases obtained throughout the study were 47%, 48%, 78%, and 56%, respectively. The LVET and HR did not change significantly, whereas the SI and CI decreased during anesthesia (29% and 26%, respectively). In conclusion, isoflurane produced direct effects on the Tei-index. The changes in systolic and diastolic parameters were supportive of this finding and were consistent with an overall impairment of left ventricular function during anesthesia.

Assesment of the TEI index of myocardial performance in dogs with doxorubicin-induced cardiomiopathy

The development of a dose-dependent cardiomyopathy is the main limitation for the use of doxorubicin in chemotherapy protocols in both humans and animals. In this setting, the global myocardial function may be compromised resulting in signs of congestive heart failure. In this study, we investigated the ability of the Tei index of myocardial performance to identify myocardial dysfunction in healthy dogs receiving doxorubicin to a cumulative dose of 210 mg/m(2) over 147 days, comparing it with other standard echocardiographic indicators of systolic and diastolic function. Our results indicated that the Tei index, the isovolumic relaxation time, pre-ejection period and the pre-ejection period-to-left ventricular ejection time ratio were able to identify the cardiotoxic effects of doxorubicin on cardiac function when only 60 mg/m(2) had been administered, while the standard systolic and diastolic parameters, including left ventricular diameter at systole, ejection fraction, and fractional shortening needed at least 120 mg/mg(2) to deteriorate. We concluded that prolonged anthracycline therapy compromises both systolic and diastolic functions, which may be documented earlier by including the Tel index evaluation to the standard echocardiographic assessment of animals receiving doxorubicin.
