Revista de Ciências Agrárias , 2011,
Abstract: the study was carried out over 2 years (2007/2008 and 2008/2009) on a private farm in the alentejo region (évora), in the south of portugal where rainfed wheat is sown after the beginning of the autumn rainfall season. the wheat crop was established using no-till which permits the post-emergence application of herbicides at an early weed development stage. to control j. bufonius and different broad-leaved weeds, a mixture of two herbicides was used when the weeds were at the 3-4 pair of leaves development stage. the herbicides applied were mesosulfuron-methyl + iodosulfuron- methyl-sodium + mefenpyr-diethyl (h1) and clortoluron (h2) at two different doses. best j. bufonius control was achieved with the higher dose of the herbicide h2 and the highest broad-leaved weeds control was obtained when the higher dose of the herbicide h1 was applied. although no significant differences in grain yield were observed between the different herbicide treatments, there was a tendency for higher grain yields with an increase of control efficacy of juncus bufonius l.

Revista Brasileira de Saúde e Produ??o Animal , 2010,
Abstract: Foram confinados 35 animais, Nelore e mesti os, com idade média de 24 ± 1 meses e peso médio inicial de 448,10 ± 26,52 kg. O abate ocorreu aos 50 dias de confinamento, com peso vivo médio final de 512,25 ± 30,03 kg. O ganho de peso diário e peso vivo final foram similares entre Nelore e mesti os, assim como os pesos de carca a quente e fria. No entanto, os rendimentos de carca a quente e fria foram maiores nos animais Nelore (52,96 versus 51,53% e 52,12 versus 50,75%, respectivamente). Nelore apresentou peso de traseiro de 6,95 kg a mais, o que refletiu diretamente na porcentagem do corte traseiro, sendo 51,63% para Nelore e 49,10% para mesti os. A porcentagem de dianteiro foi superior nos mesti os (38,35 versus 40,56%). A picanha dos animais Nelore foi mais pesada em 0,11 kg. N o houve diferen a para espessura de gordura e área de olho de lombo. Quanto aos escores de gordura e musculosidade, Nelore teve valores superiores (2,33 versus 1,93 pontos e 1,95 versus 1,71 pontos, respectivamente). O pH na carca a fria n o foi diferente. Bovinos Nelore e mesti os, confinados durante período de 50 dias, têm peso de carca a satisfatório, porém n o apresentam acabamento mínimo de 3 mm de gordura. Thirty-six animals (Nelore and crossbred) were confined, with age average of 24 months and initial average weight of 448.10kg. The slaughter occurred after 15 days adaptation and 50 days of experimental evaluation, totaling 65 days of confinement, with final average live weight of 512.25kg. The daily weigh gain and final live weight were similar between Nelore and crossbred, just like hot and cold carcass weights. Nevertheless, hot and cold carcass yields were bigger in Nelore animals (52.96 versus 51.53 and 52.12 versus 50.75%, respectively). Nelore exhibited hindquarter weight of 6.95kg more, which reflected directly in percentage of hindquarter cut, being 51.63% for Nelore and 49.10% for crossbred. The forequarter percentage was bigger in crossbred (40.56 versus 38.35%). The top sirloin cap of Nelore animals was 0.11kg heavier. There were no differences for fat thickness and loin eye area. About fat score and muscularity, Nelore had superior valuations (2.33 versus 1.93 points and 1.95 versus 1.71 points, respectively). Cold carcass pH was not different. Crossbred and Nelore animals, confined at a 65 days period, have satisfactory carcass weight, but did not present minimal fat finishing of 3mm.

Abstract: O estudo foi levado a cabo nos anos de 2007/08 e 2008/09 numa herdade privada no distrito de évora (Sul de Portugal), onde a cultura do trigo é semeada após o início das chuvas de Outono. O trigo foi estabelecido usando o sistema de sementeira directa, o qual possibilita a aplica o de herbicidas de pós-emergência numa fase mais precoce do desenvolvimento das infestantes. Para controlar o Juncus bufonius L. e diferentes infestantes de folha larga, foi aplicada uma mistura de dois herbicidas quando as infestantes se encontravam no estádio de desenvolvimento de 3-4 pares de folhas. Os herbicidas aplicados foram o mesossulfur o-metilo + iodossulfur o-metilo-sódio + mefenepir-dietilo (H1) e o clortolur o (H2) e utilizaram-se duas doses diferentes dos dois herbicidas. O maior controlo do J. bufonius foi obtido quando na mistura se utilizou a dose mais alta do herbicida H2 (2.0 L ha-1) e para se conseguir um maior controlo das infestantes dicotiledóneas foi também necessário aplicar a dose mais alta do herbicida H1 (0.3 kg ha-1). Apesar das diferen as na produ o de gr o n o terem sido significativas para os diferentes tratamentos, verificou-se a tendência de um aumento na produ o de gr o com um controlo mais eficaz do Juncus bufonius L. The study was carried out over 2 years (2007/2008 and 2008/2009) on a private farm in the Alentejo region (évora), in the South of Portugal where rainfed wheat is sown after the beginning of the autumn rainfall season. The wheat crop was established using no-till which permits the post-emergence application of herbicides at an early weed development stage. To control J. bufonius and different broad-leaved weeds, a mixture of two herbicides was used when the weeds were at the 3-4 pair of leaves development stage. The herbicides applied were mesosulfuron-methyl + iodosulfuron- methyl-sodium + mefenpyr-diethyl (H1) and clortoluron (H2) at two different doses. Best J. bufonius control was achieved with the higher dose of the herbicide H2 and the highest broad-leaved weeds control was obtained when the higher dose of the herbicide H1 was applied. Although no significant differences in grain yield were observed between the different herbicide treatments, there was a tendency for higher grain yields with an increase of control efficacy of Juncus bufonius L.

Abstract: Oxygen uptake (VO2 peak) has been very important in functional assessment of cardiorespiratory fitness. The Ergospirometry is a noninvasive procedure used to evaluate physical performance or ability of an individual, through the analysis of the gases with the respiratory variables. In sports, this method of evaluation is crucial, because it brings a significant contribution to the verification of aerobic fitness, such as, the maximal oxygen uptake (VO2 max.), and anaerobic threshold. The present study aims to evaluate the power and aerobic capacity in professional and under-20 soccer players, handball athletes, and women footballers, using the technique of gas analysis. For the study, 48 athletes, who participated voluntarily, were divided into 4 groups of 12 athletes. The VO2 peak, the average speed and heart rate at anaerobic threshold, as well as respiratory exchange ratio were analyzed. We found that the values were always greater for the group of professional football players, with the exception of the average consumption of maximum O2, where the difference of the footballers in the under-20 category was not significant. Additional values that were analyzed indicated that there were some physical similarities between the other groups that should be noted. The respiratory exchange ratio was significantly lower for the group of women footballers. Based on this data, it was concluded that the specificity of sport as dimensions of the pitch, duration, and tactical system, morphology and sex of the athlete, directly influences the values of the VO2 peak, lactate threshold and respiratory exchange ratio for athletes of different sports at the same stage of periodization of fitness.

Abstract: Foram avaliados os resultados financeiros obtidos no confinamento de novilhos Nelore, submetidos a diferentes níveis de substitui o de silagem de sorgo por cana-de-a úcar ou baga o de cana amonizado com ureia. Foram confinados 35 animais machos n o castrados com idade média de 24 meses, peso médio inicial de 448,2kg, distribuídos em 7 tratamentos: 100% silagem de sorgo; 70% de silagem de sorgo + 30% de cana-de-a úcar; 30% de silagem de sorgo + 70% de cana-de-a úcar; 100% de cana-de-a úcar; 70% de silagem de sorgo + 30% de baga o de cana amonizado com ureia; 30% de silagem de sorgo + 70% de baga o de cana amonizado com ureia e 100% de baga o de cana amonizado com ureia. O concentrado fornecido correspondeu a 1,2% do peso corporal. Para avalia o econ mica dos resultados, foram analisados os diferentes componentes dos tratamentos utilizados no experimento e os resultados de ganho de peso obtidos, e o peso médio final foi de 512,3kg. O tratamento com 100% de silagem de sorgo apresentou a melhor eficiência econ mica, seguido pela cana-de-a úcar e pelo baga o de cana-de-a úcar amonizado usados isoladamente, com cobertura do total dos custos operacionais e apresenta o do resíduo positivo. As diferentes combina es de silagem de sorgo e cana-de-a úcar e as de baga o de cana-de-a úcar amonizado e silagem de sorgo apresentaram desempenho econ mico insuficiente para cobrir os custos operacionais totais. It was evaluated the financial result of the confinement of Nelore bovines, subdued to different levels of substitution of sorghum silage by sugarcane or sugarcane bagasse ammoniated with urea. It were confined 35 young bulls with age average of 2 years, initial average weight of 448,2kg distributed in 7 treatments: 100% of sorghum silage; 70% of sorghum silage + 30% of sugarcane; 30% of sorghum silage + 70% of sugarcane; 100% of sugarcane; 70% of sorghum silage + 30% of sugarcane bagasse ammoniated with urea; 30% of sorghum silage + 70% of sugarcane bagasse ammoniated with urea and 100% of sugarcane bagasse ammoniated with urea. Concentrate was provided in the amount corresponding to 1.2% of body weight. It were analyzed the different components of the fodder used in the trial and the results of weight gain acquired, with final average weight of 512.3kg. The treatment with 100% of sorghum silage showed the best economic efficiency, followed by sugarcane and sugarcane ammoniated bagasse used alone, covering the total operational costs and showing positive residue. Different combinations of sorghum silage with sugarcane or with sugarcane ammoniated bagasse showed
