Abstract: The shunt portosystemic or portosystemic deviation (PSD) are unique or multiples vascular communications between the systemic circulaton and the portal circulation, that permit blood flow reaches the circulatory system without first passing trhought the hepatic metabolization. May be acquired or congenital and can also be classified as intrahepatic located within the liver or extrahepatic located outside the liver parenquima. The acquired form is usually associated with intra-hepatic disorders. They usually suggest tortuous vessels that communicate with the caudal vena cava in the region of the left kidney. The congenital form is associated with genetic lineage and one of the most affected is Maltese breed. This case report describes the diagnostis and treatment of a eight year-old female Maltese dog presenting extrahepatic Portosystemic Shunt. The patient showed signs of hepatic encephalopathy, such as restlessnees, weakness, deambulation, head tremor and impaired visual. Complementary exam demonstrated: postprandial glicemia near the lower limit of reference, alkaline phosphatase (ALP) and alanine aminotransferase (ALT) increased and hipoalbuminemia. Ultrasonography revealed the presence of vesical calculus and bilateral kidney, liver decreases and increased echogenicity, gallbladder with anechoic content and high cellularity may suggest liver/ colangiohepatopatia and extrahepatic DPS was detected. The use of Doppler assisted in identifying the location of the bypass communication and the turbulence detecting the extrahepatic DPS. Protein-restricted diet and antibiotic therapy with amoxicillin achieved good results. The clinical treatment was decided make only the clinical and maintain the quality of life of the patient. Objetivou-se avaliar a degradabilidade ruminal e a taxa de degrada o in situ da matéria seca (MS), da proteína bruta (PB) e da fibra em detergente neutro (FDN), dos fenos de alfafa e Tifton-85 e da silagem de milho. Foram utilizadas três vacas fistuladas no rúmen, adaptadas às dietas por um período de 15 dias e incubadas com as amostras em sacos de náilon por três dias. Os tempos de incuba o utilizados foram: 0, 2, 6, 12, 24, 48 e 72 horas. Após a remo o, os sacos foram lavados ligeiramente em água corrente e em seguida congelados até a completa remo o dos demais. A degradabilidade efetiva (DE) da matéria seca, da proteína bruta e da fibra em detergente neutro do feno de alfafa mostrou-se (P<0,05) superior ao feno de Tifton-85 e a silagem de milho. As degradabilidades potenciais (DP) e efetivas (DE), para taxa de passagem de 5 e 8

Abstract: It was aimed at to determine the dehydration curve and the moisture content effect during the baling process in the chemical composition of star grass (Cynodon nlemfuensis Vanderyst) hay. Samples were collected from harvest until baling to determine the dehydration curve of both whole plant and leaf and stem fractions. The baling process occurred with predetermined moisture contents: 25, 16 and 12%. A completely randomized experimental design with ten replications was used, and the chemical bromatological composition data were compared by Tukey Test (5%). The water loss rate was higher for leaf when compared to stem fraction. In the early hours after storage, it was noticed higher heat for hays with 25% of moisture content. There was not effect of moisture content during baling process in the chemical composition of star grass hay, except for crude protein (CP) and ether extract (EE). In vitro dry matter digestibility (INDMD) and in vitro crude protein digestibility (INCPD) were not affected by moisture content in baling process either. It was concluded that the moisture content during the baling process does not affect the chemical composition of star grass hay in advanced stadium of development, except for crude protein and ether extract. Objetivou-se determinar a curva de desidrata o e o efeito do teor de umidade no enfardamento sobre a composi o químico-bromatológica do feno de grama-estrela (Cynodon nlemfuensis Vanderyst). Foram realizadas amostragens do momento do corte até o enfardamento, a fim de determinar a curva de desidrata o da planta inteira e das fra es folha e colmo, com secagem em estufa de ventila o for ada e em forno de microondas. A gramínea foi enfardada com teores de umidade pré-estabelecidos de 25, 16 e 12%, em delineamento experimental inteiramente casualizado com dez repeti es. A taxa de perda de água foi maior para a fra o folha comparada à fra o colmo. Houve maior aquecimento para os fenos enfardados com 25% de umidade nas primeiras horas após a armazenagem. N o houve efeito dos teores de umidade no enfardamento sobre a composi o química do feno de grama-estrela, exceto para o teor de proteína bruta e extrato etéreo. A digestibilidade in vitro da matéria seca e da proteína bruta n o apresentaram efeito do teor de umidade no enfardamento, com valores médios de 58,73 e 55,42%, respectivamente. O uso de forno de microondas para determinar o teor de umidade da forragem apresentou eficiência semelhante ao método de secagem em estufa com circula o for ada de ar. Nas condi es deste estudo os teores de umidade no momento do

Abstract: The objective of this work was to evaluate the effects of corn (Zea mays L.) silage and elephant-grass (Pennisetum purpureum Schum) silage on the nutrition of cows during lactation, over some of the blood constituents (glucose, triglycerides and urea). The treatments were three silages (corn silage, elephant-grass silage with bacterial inoculating, elephant-grass silage with enzyme-bacterial inoculating). Nine Holstein cows, with a medium weight of 520 kg, were distributed in experimental delineation of simultaneous triple Latin square. The blood glucose rates were considered normal, independents of the silage used. Concerning the triglicerides levels, it was verified that they are below normal to the different silages. One of the reasons would be the low fat level on the diet. The blood levels of urea observed on the three treatments are considered normal. There was not significant difference among the different kinds of silage in relation to the blood levels of urea, glucose and triglycerides. O objetivo deste trabalho foi avaliar os efeitos do fornecimento de silagem de milho (Zea mays L.) e silagem de capim-elefante (Pennisetum purpureum Schum) na alimenta o de vacas em lacta o, sobre alguns dos constituintes sangüíneos (glicose, triglicerídeos e uréia). Os tratamentos foram três silagens (silagem de milho, silagem de capim-elefante com inoculante bacteriano, silagem de capim-elefante com inoculante enzimo-bacteriano). Foram utilizadas nove vacas da ra a holandesa, com peso médio de 520 kg, distribuídas em delineamento experimental de triplo quadrado latino simultaneo. As taxas de glicose sangüínea das vacas foram consideradas normais, independente do volumoso utilizado. Em rela o aos níveis de triglicerídeos, verificou-se que est o abaixo do normal para os diferentes volumosos. Uma das raz es seria o baixo nível de gordura na dieta. Os níveis sangüíneos de uréia observados nos três tratamentos s o considerados normais. N o houve diferen a significativa entre os volumosos em rela o aos níveis sangüíneos de uréia, glicose e triglicerídeos.

Abstract: The characteristics of lamb meat are influenced by a series of factors, among which the testicular hormone production. In order to estimate the influence on meat characteristics, 24 Suffolk, Ile de France, Santa Inês and Texel crossbred lambs male, in a completely casualised delineation, with three treatments and eight repetitions. All animals were managed in the same way, pasture-raised and fed on native grass, in a Voisin system. The experiment treatments were constituted of non-castrated, castrated and cryptorchid animals. Live weight measurements were recorded at birth, once a month to assess body development and before slaughter. The warm carcass weight at slaughter and the 24 hours post-slaughter weight of the carcass cooled in refrigeration chamber at 5oC were recorded. Also, the weights of the variables related to the carcass were obtained. The results were analyzed using GLM Procedure and the means compared by Tukey’s test at the 5% significance level. No differences in production were found in the components and in the characteristics of the ovine meat and carcass of non-castrated, castrated and cryptorchid lambs raised on pasture land, fed on native grass and slaughtered young. O objetivo deste trabalho foi avaliar os efeitos de diferentes porcentagens de gr os de soja crus, adicionados aos gr os de milho, sobre as características de fermenta o e composi o química das silagens. Os tratamentos testados foram, silagem de gr os de milho com inclus o de 0, 10, 20, 30, 40% de gr os de soja crus. Foram utilizados silos experimentais com capacidade para aproximadamente 12 kg de silagem, sendo que esses permaneceram vedados por um período de 12 meses, quando foram abertos para amostragens e análises químicas. O delineamento experimental empregado foi inteiramente casualizado, com três repeti es por tratamento. A adi o de gr os de soja proporcionou aumento nos teores dos nutrientes (MM, PB, EE) das silagens, sem interferir na qualidade de conserva o das mesmas.

Abstract: Neste trabalho objetivou-se avaliar o efeito de concentrados à base de silagens de gr os de milho puro ou com adi o de gr os de girassol ou ureia sobre a composi o, desempenho e rendimento de carca a de cordeiros Hampshire Down- sem ra a definida (SRD), terminados em confinamento. Foram avaliados três tratamentos sendo: silagem de gr os de milho (SGM); SGM com adi o de gr os de girassol (SGMG); SGMcom adi o de ureia (SGMU). Utilizaram-se 24 cordeiros machos inteiros, com peso médio inicial de 23 kg, distribuídos nos tratamentos (8 animais tratamento-1). Após o abate, as carca as foram pesadas para obten o do peso da carca a quente (PCQ) e armazenadas emcamara frigorífica a 4°C, por 24h para obten o do peso da carca a fria (PCF). O peso vivo médio ao abate foi de 31,1 kg com ganho médio diário (GMD) de 0,164 kg. O PCQ médio foi de 13,4 kg com rendimento médio de 43,13%, enquanto o PCF foi de 12,8 kg. N o houve efeito dos tratamentos sobre estas variáveis, evidenciando que a qualidade dosconcentrados foi semelhante. A silagem de gr os de milho associados com gr os de girassol ou ureia, na alimenta o de cordeiros, n o influencia as variáveis quantitativas da carca a, sendo recomendado seu uso na formula o de concentrados. Effect of concentrated compounds either with unmixed corn silages or with sunflower or urea on the composition, performance and carcass yield of Hampshire Dow and without definite race lambs finished in feedlots was evaluated. Three treatments were evaluated: corn grain silages (CGS); CGS with sunflower grains; SGS with urea. Twenty-four male lambs, mean initial live weight of 23 kg, allotted in treatments (8 animals treatment-1), were employed. After slaughter, carcasses were weighed for hot carcass weight (HCW) and then refrigerated at 4°C for 24 hours for cold carcass weight (CCW). Mean live weight at slaughter was 31.1 kg with mean daily gain (MDG) of 0.164 kg. Mean HCW was 13.4 kg with a mean yield of 43.13% while mean CCW reached 12.8 kg. Since treatments did not affect variables, quality of concentrates was similar. Corn grains silages with sunflower grains and urea in lamb feed failed to affect the carcass’s quantitative variables and their use is recommended for concentrates.

Abstract: O objetivo do trabalho foi avaliar a influência da composi o químicobromatológica da dieta total e os fatores ambientais das esta es do ano sobre a composi o química do leite. As granjas leiteiras estudadas foram identificadas como Granja 1 (G1) e Granja 2 (G2). Definiram-se como tratamento as quatro esta es do ano e os dois sistemas de produ o leiteira (G1 e G2). Foram coletadas 34 amostras da dieta total fornecida aos animais em lacta o para a análise da composi o químico-bromatológica, e 20 amostras de leite cru diretamente dos tetos dos animais para avaliar a composi o química do leite, durante as quatro esta es ano. Para as análises estatísticas dos dados, foi empregado o método dos quadrados mínimos. Constatou-se que houve diferen a (p < 0,05) entre a G1 e a G2 para a produ o de leite (kg dia-1), porcentagens de gordura, proteína e níveis de ureia no leite (NUL). No entanto, n o houve diferen a na porcentagem de lactose e sólidos totais entre as granjas estudadas. Observou-se que a produ o (kg dia-1) e todos os componentes do leite analisados diferiram ao longo das quatro esta es do ano. Os resultados demonstraram que a composi o químico-bromatológica da dieta, as fases de lacta o e os fatores ambientais das esta es do ano podem causar varia es na produ o e composi o química do leite. The objective of this research study was to evaluate the influence of total diet chemical composition and environment factors of thedifferent seasons of the year on the chemical composition of milk. The milk farms evaluated were classified as Farm 1 (G1) and Farm 2 (G2). The study defined as treatments the four seasons of the year and the milk production system (G1 and G2). A total of 34 diet samples were collected, fed to lactating animals in order to analyze the chemicalbromatological composition, and 20 samples of raw milk straight from cows in order to evaluate the chemical composition of milk during the four seasons. For data statistical analyses, the method of least squares was used. There was a difference (p < 0.05) between the G1 and G2 farms, for milk production (kg day-1), fat, protein and milk urea nitrogen (MUN) percentages. However, no difference was observed (p > 0.05) in lactose and total solids percentage between the studied farms. On the other hand, it was observed that the production (kg day-1) and all analyzed milk components were different (p < 0.05) during the four seasons of the year. The results demonstrate that the total diet chemical composition, lactation phases and environments factors of seasons of the year may cause vari

Abstract: The objective of this study was to determine the dehydratation rate of after-harvest forage in the field conditions and to evaluate the chemical composition as a function of nitrogen fertilization. It was used two fertilization levels (50 and 100 kg/N/ha) and forage was harvest with 28 days growth. During field wilting, one sample at harvest time and seven others after it were collected to determine the dehydratation rate of the whole plant and the leaf and stem fractions. A completely randomized experimental design with ten replications was used, and the chemical composition data were compared by F Test (5%). The water loss rate was higher for leaf when compared to stem fraction, showing the same pattern for both fertilization levels. In chemical composition evaluations, crude protein (CP) was different (P0.05). In vitro dry matter digestibility (INDMD) and in vitro crude protein digestibility (INCPD) were not affected (P>0.05) by the levels of nitrogen fertilization. Nitrogen fertilization increased the CP concentration in Stargrass hay, but did not affect the fiber fraction, not increasing the nutritional quality of hay. O objetivo do trabalho foi determinar a taxa de desidrata o da forragem após o corte, em condi es de campo e avaliar a composi o química em fun o da aduba o nitrogenada. Utilizou-se dois níveis de aduba o (50 e 100 Kg/N/ha) com o corte realizado após 28 dias de crescimento. Durante o período de secagem a campo foram realizadas amostragens no momento do corte e mais outras sete após o corte, para determinar a taxa de desidrata o da planta e das fra es folha e colmo. O delineamento experimental foi inteiramente casualizado com dez repeti es e os dados de composi o química, comparados pelo teste F (5%). A velocidade de perda de água foi maior para a folha comparada ao colmo, mostrando o mesmo padr o para os dois níveis de aduba o. Na avalia o da composi o química, a PB diferiu (P0,05) para o nível de nitrogênio. Da mesma forma, para a DIVMS e DIVPB n o houve efeito (P>0,05) entre os níveis de aduba o nitrogenada. A aduba o nitrogenada proporcionou aumento no teor de PB do feno de grama-estrela, porém n o afetou os componentes da fibra, n o resultando em aumento na qualidade nutricional do feno.

Abstract: Objetivou-se avaliar o desempenho e a qualidade do leite produzido por vacas da ra a Holandesa no ter o final da lacta o, alimentadas com silagens de grama estrela com aplica o de inoculante ou uréia em rela o à silagem de milho. Foram avaliadas silagens de grama estrela com aplica o de aditivo enzimo-bacteriano na dosagem de 80 g deinoculante/tonelada, uréia na dosagem de 7 kg t-1 e silagem de milho. Para avalia o do desempenho produtivo e digestibilidade foram utilizadas seis vacas da ra a Holandesas com peso médio de 480 kg distribuídas em delineamento (duplo) quadrado latino (3 x 3). Asdigestibilidades da MS, PB e FDN foram maiores para a silagem de milho. O fornecimento de silagens de grama estrela com aditivo e com uréia n o interferiu na produ o e qualidade do leite, mostrando-se como alternativa para sistemas de produ o animal com base emvolumosos conservados mediante a análise econ mica da substitui o da silagem de milho. The study aimed to evaluate animal performance and quality of milk from Holstein cows during the final third period of lactation fed stargrass silages supplied with inoculant or urea in relation to corn silage. Stargrass silages with enzymatic-bacterial inoculant (80 g of additive/ton of silage), urea supply (7 kg t-1) and corn silage were evaluated. Six Holstein cows with an average body weight of 480 kg were allocated in a double Latin square design (3 x 3). Corn silagepresented the highest values of DM, CP and NDF digestibility when compared to stargrass silages. Supplying Holstein cows with stargrass silages with additive and urea did not promote any effect on production and milk quality. Thus, it can be an alternative in animalproduction systems based on conserved roughage, depending on economical analysis for the replacement of corn silage.
