Abstract: Verificou-se o sistema de termina o de 44 cordeiras Dorset Santa Inês na freqüência, diametro de fibras musculares esqueléticas e desempenho. Amostras do músculo semitendinosus foram coletadas para análise do diametro, frequência e efeito de modula o das fibras musculares do desmame e abate. As cordeiras foram divididas em dois sistemas de termina o. Pastagem com suplementa o (1,5% PV) com 27,01% PB e 4,51 Mcal de EB kg-1 MS e no confinamento receberam ra o (4% PV) com 15,56% de PB e 4,32 Mcal de EB kg-1 MS. O ganho de peso médio diário (GPMD) foi de 0,157 e 0,148 kg para confinamento (CT) epastagem mais suplementa o (PS), respectivamente. Os diametros das fibras SO, FOG e FG para CT e PS, foram, respectivamente, 29,04 e 28,55, 34,46 e 35,80 e 38,81 e 40,96 μm. Frequência das fibras SO, FOG e FG para CT e SO, foram, respectivamente, 19,32 e 21,35, 43,88 e 43,53 e 36,80 e 35,12%. Correla o positiva entre o ganho médio diário das cordeiras conforme ocorreu aumento no diametro das fibras, tanto para CT e PS. Para a variável GPMD, as cordeiras podem ser terminadas, tanto no confinamento ou na pastagem mais suplementa o.As características morfológicas, histoquímicas e efeito de modula o foram semelhantes, para qualquer um dos sistemas de termina o. Verify the effect of the termination system the forty-four Dorset Santa Inês lambs in the frequency, diameter of skeletal muscular fibers and performance. Samples the semitendinosus muscle were collected for diameter analysis, frequency and modulation effect at weaning and slaughter. After weaned, the lambs were distributed in two finishing systems. Feedlot received ration (4% BW) with 15.56% of CP and 4.32 Mcal de GE kg-1 of DM, while those on pasture received supplementation (1.5% BW) with 27.01% CP and 4.51 Mcal of GE kg-1 of DM. The average daily gain (ADG) was 0.157 and 0.148 kg for feedlot (TF) and pasture + supplementation (PS). The diameters of skeletal muscle fibers SO, FOG and FG for TF and PS were 29.04 and 28.55, 34.46 and 35.80, and 38.81 and 40.96 μm, respectively. Frequency of skeletal muscle fibers SO, FOG and FG for TF and PS, were 19.32 and 21.35, 43.88 and 43.53, and 36.80 and 35.12%, respectively. Positive correlation was verified for lamb performance with the diameter, both for CT and PS. For the ADG variable, lambs could be either finished on TF or PS. The morphological and histochemical characteristicsand modulation effect were similar, for either of the two finishing systems.

Abstract: Objetivou-se avaliar a composi o química e as perdas totais de MS na silagem de soja colhida em diferentes estádios reprodutivos. O trabalho foi dividido em dois períodos experimentais, safras de 2005 e de 2006. Foram determinados quatro estádios reprodutivos (R3, R4, R5 e R6) como tratamento no Experimento I (2005) e três estádios reprodutivos (R5, R6 e R7) no Experimento II (2006). O material foi acondicionado em silos experimentais de PVC, sendo as amostragens efetuadas na abertura do silo (60 dias após a ensilagem) para avaliar a composi o química. No Experimento I, houve diferen as (p < 0,05) nos quatro estádios reprodutivos para os teores de MS, CZ, MO, PB, LIG, EE e CT. N o se verificou diferen a (p > 0,05) para os valores de FDN, FDA, NIDN, NIDA, CEL, CHO e pH. No Experimento II, as silagens n o apresentaram diferen as (p > 0,05) para o teor de MS, CZ, MO, PB, FDN, FDA, EE e CHO em fun o do estádio de desenvolvimento da cultura de soja. Os valores de pH, CE e CT das silagens apresentaram diferen as (p < 0,05) entre os estádios reprodutivos. O avan o do estádio reprodutivo altera o valor nutricional da silagem da planta inteira de soja. O déficit hídrico influencia negativamente o desenvolvimento adequado dos gr os de soja,ocasionando prejuízo especialmente em rela o ao valor proteico da silagem. This trial was carried out to study the chemical composition and total DM losses of soybean silage at different reproductive stages. The work was divided in two evaluation periods: the 2005 and 2006 harvests. Four reproductive stages were determined (R3, R4, R5 and R6) as treatments in trial I (2005) and three reproductive stages (R5, R6 and R7) in trial II (2006). The material was conditioned in PVC experimental silos, and the samples were taken at the time thesilo was opened (60 days after ensilage) to evaluate the chemical composition. In trial I, there were differences (p < 0.05) in the four reproductive stages for DM, ash, OM, CP, LIG, EE and BC. No differences were observed (p > 0.05) for NDF, ADF, NDIN, ADIN, CELL, total carbohydrate and pH. In trial II, the silages did not present differences (p > 0.05) for DM, ash, OM, CP, NDF, ADF, EE and total carbohydrate in function of the soybean harvest stage. The pH values, electric conductivity and buffering capacity of the silages were different (p < 0.05) among the reproductive stages. The advance of reproductive stage changes the nutritional value of whole-plant soybean silage. The water deficit adversely affects the suitable development of soybeans, where the protein value of silage is penalized.

Abstract: The trial was performed to evaluate the effect of phosphorus sources on forage mass quality of Momba a grass (Panicum maximum Jacq. cv. Momba a), according to in vitro dry matter and organic matter digestibility and TDN concentration. Every month, samples of available forage mass were taken, from December, 2002 until April, 2003. The treatments were three phosphate sources (1-Yoorin ê magnesium thermophosphate; 2-Gafsa ê natural phosphate; 3-simple superphosphate + triple superphosphate) and the control (no fertilizer). They were arranged in a randomised block design with three replications. It was used 12 plots sized from 0,7 to 1,0 hectare, which were delimited by two-line eletric fence. The grazing method was continuous stocking and variable stocking rate (“put-and-take”). The IVDMD, IVOMD and TDN coefficients decreased along sampling period. IVDMD, IVOMD and TDN concentration didn’t show significantly differences among treatments (P>0.05). O trabalho foi realizado com o objetivo de avaliar o efeito de fontes de fósforo sobre a qualidade de massa de forragem do capim-Momba a (Panicum maximum Jacq. cv. Momba a), no que se refere à digestibilidade “in vitro” da matéria seca e da matéria organica e concentra o de NDT. Foram feitas amostragens mensais da massa de forragem disponível, no período de dezembro de 2002 a abril de 2003. Os tratamentos avaliados foram três fontes de fósforo (1-termofosfato magnesiano Yoorin ê; 2-fosfato natural Gafsa ê; 3-superfosfato simples + superfosfato triplo) e tratamento testemunha, distribuídos em delineamento de blocos casualisados com três repeti es. Foram utilizados 12 piquetes com tamanho de 0,7 a 1,0 hectare, separados por cerca com dois fios eletrificados. O método de pastejo utilizado foi o da lota o contínua com carga variável (“put-and-take”). Os coeficientes de DIVMS, DIVMO e NDT reduziram ao longo do período de coleta. Entre os tratamentos, a DIVMS, DIVMO e concentra o de NDT n o tiveram diferen a significativa (P>0,05).

Abstract: It was aimed to evaluate in this trial the effect of additive and urea supplies on ruminal degradabilty and carbohydrates fractioning of stargrass silages. There were evaluated silage without additive (SGE), silage with enzymatic-bacterial additive (SGE150 and SGE300 respectively, 150 and 300 g of additive/ton of silage) and silage with urea (SGEU, 10 kg/ton). Three Holstein steers were used in blocks randomizeds design for ruminal degradability assay. The effective degradability (ED) of DM and NDF were higher (P < 0.05) for SGE300 treatment for all flow rates. There was difference (P < 0.05) for ED of CP in silage supplied with urea. Total carbohydrates presented the highest values for no additive treatment, while A+B1 and B2 fractions didn’t differ (P > 0.05) among treatments. Silages with additive presented the lowest values (P < 0.05) of C fraction. It was concluded that additive or urea supply in stargrass silages didn’t improve the potential degradability (PD) when compared to the silage without additive. Objetivou-se com o estudo avaliar o efeito de aditivo enzimo-bacteriano e de uréia sobre a degradabilidade ruminal e o fracionamento de carboidratos em silagens de grama estrela. Foram avaliadas silagens sem aditivo (SGE) e com aplica o de aditivo enzimo-bacteriano (SGE150 e SE300, respectivamente 150 e 300g aditivo/tonelada) e uréia (SGEU, 10 kg/tonelada). Para o ensaio de degradabilidade foram utilizados três bois da ra a Holandesa distribuídos em blocos casualizados. A degradabilidade efetiva (DE) da MS e da FDN foram maiores para o tratamento SGE300 em todas as taxas de passagem. Para a DE da PB houve diferen a (p < 0,05) para o tratamento SGEU. Os carboidratos totais (CHT) tiveram os maiores valores para o tratamento SGE, enquanto que, para as fra es A+B1 e B2 n o houve efeito significativo entre os tratamentos. Para a fra o C os menores valores foram para os tratamentos com inoculante. Conclui-se que a aplica o do inoculante ou uréia n o melhoraram a degradabilidade potencial (DP) das silagens de grama estrela em rela o ao tratamento isento da aplica o de inoculante.

Abstract: We report new data on the intersexual and geographical variation in body mass of the Geoffroy's cat (Oncifelis geoffroyi d'Orbigny and Gervais 1844), a little known small cat from South America, and combine them with the existing information to compare alternative hypotheses for variation in body mass. Most data on the body mass of O. geoffroyi have been obtained from previous research on this felid in four study areas of southern Brazil and central and southern Argentina. These data were added to those reported for other three additional locations. Our results set the body mass of O. geoffroyi to 4.26 ± 1.03 kg (mean ± SD, n = 56). We also show that males generally are heavier than females throughout most of this species' distributional range. Body mass dimorphism is 1.34 on average, but ranges from 1.19 and 1.21 in Uruguay and southern Chile, respectively, to 1.76 in the northern Pampas of Argentina. When data from the best sampled areas are considered (Torres del Paine, Lihué Calel, southern Pampas, Campos del Tuyú and southern Brazil), only male body mass varies with geographic location. More intriguingly, no correlation was found between body mass and latitude. Our results suggest a smaller mean weight of O. geoffroyi relative to what was previously published, but also suggest a wider variation. Our analysis do not support Bergmann's rule, according to which the largest individuals would occur in the southernmost regions of this cat's geographic distribution, while they seem supportive of a sexually-selected process affecting sexual size dimorphism in the Geoffroy's cat Se reportan nuevos datos sobre la variación intersexual y geográfica de la masa corporal en el gato montés (Oncifelis geoffroyi d'Orbigny and Gervais 1844), un félido peque o y poco conocido de América del Sur, y los combinamos con la información existente para evaluar dos hipótesis que explicarían esta variación. La mayor parte de los datos sobre masa corporal de O. geoffroyi fueron obtenidos en el marco de proyectos de investigación sobre este félido en cuatro áreas del sur de Brasil y centro y sur de Argentina. Estos datos se agregaron con registros para otras tres localidades. Nuestros resultados establecieron que la masa corporal promedio de O. geoffroyi fue de 4,26 kg (DE = 1,03 kg; n = 56). Demostramos además que los machos son más grandes que las hembras, y que este dimorfismo sexual ocurre en la mayoría de las localidades muestreadas a lo largo del rango de distribución de esta especie. El dimorfismo sexual en la masa corporal fue de 1,34 en promedio, pero varió entre 1,19
