ABSTRACT. The objective of this study was to evaluate productive performance and egg quality of Japanese quails (Cortunix japonica) fed with synthetic and natural pigments. The treatments used were: 0.8% paprika extract (Capsicum annuum), 0.8% marigold flower extract, 4% paprika extract and 4% marigold flower extract and 0.045% synthetic pigment (Canthaxanthin) in feed. A total of 240 Japanese quails at 20 weeks of age were distributed in a completely randomized experimental design with five treatments and six replicates, with eight quails per experimental unit (30 experimental units). There was no difference (p > 0.05) for the evaluated parameters, except for yolk color which showed significant difference (p < 0.05) between the treatments used. The inclusion of 0.8% natural pigments in diet of Japanese quails can be used to substitute canthaxathin because it is effective on improving yolk color without affect performance and the quails egg quality.

ABSTRACT. The objective was to evaluate the performance, egg quality, thermoregulation, body morphology and behavior of different categories of laying poultry. Two treatments with two genetic groups were used, 50 birds of the Hisex Brown strain and 50 birds of the Black Avifran chicken breed with 55 weeks, distributed in a completely randomized design with 10 replicates and 5 birds in each experimental unit. The variables egg weight, weight and percentage of albumen, yolk and shell, marketable eggs, specific gravity, color b *, egg / poultry production day-1 were not different (p > 0.05) between the two groups. Feed conversion by egg mass and dozen eggs, yolk color, L color, diameter, height, shell color presented a difference (p < 0.05), being higher values for the Black Avifran breed. The Black Chicken Avifran had higher body temperature; however, its performance and the quality of its eggs did not change. Black Chicken Avifran presented higher values in relation to body morphology, and better results in relation to the animal performance, therefore, it was more efficient, since it obtained a lower consumption and production equal to the lineage Hisex Brown, when created in the Cage - Free system.

RESUMO A sobrevida de pacientes cirróticos críticos aumentou significantemente nos últimos anos devido a inúmeros avanços obtidos no manejo do paciente com cirrose descompensada e com insuficiência hepática aguda grave, particularmente após a incorporação na prática clínica de uma série de estratégias baseadas em evidencias com impacto reconhecido na redução de mortalidade. Com o intuito de discutir as principais evidencias disponíveis na literatura médica sobre o assunto, a Sociedade Brasileira de Hepatologia, em conjunto com a Associação de Medicina Intensiva Brasileira e a Associação Brasileira de Transplantes de Órgãos promoveu uma reunião monotemática sobre o manejo do paciente hepatopata crítico, que ocorreu em 21 de maio de 2014 na cidade do Rio de Janeiro. O relatório da reunião foi resumido no presente manuscrito com o objetivo de nortear a prática clínica de intensivistas, gastroenterologistas e hepatologistas no manejo do paciente hepatopata em ambiente de terapia intensiva.

ABSTRACT Survival rates of critically ill patients with liver disease has sharply increased in recent years due to several improvements in the management of decompensated cirrhosis and acute liver failure. This is ascribed to the incorporation of evidence-based strategies from clinical trials aiming to reduce mortality. In order to discuss the cutting-edge evidence regarding critical care of patients with liver disease, a joint single topic conference was recently sponsored by the Brazilian Society of Hepatology in cooperation with the Brazilian Society of Intensive Care Medicine and the Brazilian Association for Organ Transplantation. This paper summarizes the proceedings of the aforementioned meeting and it is intended to guide intensive care physicians, gastroenterologists and hepatologists in the care management of patients with liver disease.

Este trabalho teve como objetivos avaliar a cinética de passagem da digesta, as características físico-químicas e o tamanho da partícula da digesta do cólon ventral direito (CVD) de equinos alimentados com feno de coastcross com diferentes tamanhos de partículas. Utilizaram-se quatro equinos fistulados CVD alimentados exclusivamente com feno de coastcross: inteiro; feno picado, moído (5 mm) e moído (3 mm). Utilizou-se o delineamento em quadrado latino 4x4. Cada período experimental teve 10 dias de adaptação às dietas, quatro dias de coleta de fezes e um dia de coleta do conteúdo do cólon. A cinética de passagem da fase sólida e líquida da digesta no trato digestório foi estimada através do tempo médio de retenção (TMR), da taxa de passagem (k) e do tempo de trânsito (TT) utilizando os indicadores: Cr-FDN e Co-EDTA. O TT da fase sólida da digesta foi maior em 3 horas (P<0,05) nos equinos alimentados com o feno moído, em relação às outras formas do feno. Não houve diferença (P>0,05) no TMR e k tanto da fase líquida quanto na sólida da digesta em função das diferentes formas físicas do feno. No entanto, houve maior velocidade de passagem da fase líquida de 3,28 h-1, comparada à fase sólida, de 2,73 h-1, em todas as dietas. Quando se forneceu feno moído a 3 mm foram observados o menor tamanho de partícula e o menor teor da fibra em detergente neutro na digesta do cólon, com valores de 0,51 mm e 53,5%, respectivamente. A moagem do feno aumentou o tempo de trânsito da fase líquida no trato digestório dos equinos, sem interferir na cinética da fase sólida da digesta. A moagem do feno reduziu os teores de FDN e o tamanho médio das partículas no CVD.

This study was conducted to evaluate the kinetics, physicochemical characteristics and particle size of digesta in the right ventral colon (RVC) of horses fed coastcross hay ground to different degrees. Four horses fitted with cannulae in the RVC were used and were fed the following forms of hay: long, chopped, ground to 5 mm and ground to 3 mm. A Latin Square 4x4 study design was used. Each experimental period included 10 days for diet adaptation, four days for feces collection and one day for digesta collection. The kinetics of the particulate and solute phases of digesta were evaluated based on the mean retention time (MRT), passage rate (k) and transit time (TT) using two external markers: Cr-NDF and Co-EDTA. The TT of solid phase digesta was 3 hours longer (P<0.05) for ground hay than with the other physical forms of hay. There was no difference (P>0.05) in k or MRT in either the liquid or solid phase of digesta as a function of the different degrees of hay grinding. However, the liquid phase of digesta presented a higher k than the solid phase, with values of 3.28 and 2.73 h-1 being obtained, respectively. The smallest particle size and the lowest neutral detergent fiber contents in colon digesta were observed when hay ground to 3 mm was offered, leading to values of 0.51 mm and 53.46%, respectively. Grinding the hay increased the transit time of the liquid phase in the digestive tract of the horses, whereas no change in the kinetics of the solid phase digesta was observed. The grinding of hay reduced the NDF and the average particle size in the right ventral colon.

This study was carried out to evaluate the creatine and maltodextrine dietetic supplementation of eventing horses. The experimental period consisted of 56 days, with 20 horses, which were randomly divided into four groups with different diets. Diets were: diet without supplement (Control); diet supplemented with creatine, 44.4 mg/kg body weight/day (20 g creatine/horse/day); diet supplemented with creatine, 88.8 mg/kg body weight/day (40 g creatine/horse/day); diet supplemented with maltodextrine, 222.2 mg/kg body weight/day (100 g/horse/day), during three days before each test. Every horse was submitted to three tests. Blood samples and heart rate were collected at rest, immediately after the tests and 10 and 20 minutes after the test. Supplementation with creatine (44.4 mg/kg body weight/day) and maltodextrine reduced plasma concentration of lactate in horses during tests. Supplementation of creatine and maltodextrine did not alter serum concentration of aspartate aminotransferase, γ-glutamyltransferase, urea or creatinine, but training affected blood biochemical variables in eventing horses.

Objetivou-se avaliar os parâmetros fisiológicos, hematológicos e bioquímicos de equinos de concurso completo de equitação consumindo dieta contendo óleo de soja e submetidos a testes de esforço físico. Foram utilizados 12 equinos em delineamento experimental inteiramente casualizado, com duas dietas e seis repetições. As dietas utilizadas foram: dieta sem inclusão de óleo de soja (controle); dieta com inclusão de 10% de óleo de soja. O ensaio teve duração de 82 dias e incluiu três testes de esforço físico: ao início, no 60º e no 82º dia. Em cada teste, foram realizadas cinco coletas de dados: antes do teste com os animais em repouso; imediatamente após o teste; e 10, 20 e 120 minutos após os testes. Foram avaliadas a temperatura corporal e a frequência cardíaca e realizadas coletas de amostras de sangue para análises hematológicas e bioquímicas. Os valores médios dos parâmetros fisiológicos, hematológicos e bioquímicos foram submetidos à análise não-paramétrica. Somente ao longo do tempo de consumo das dietas, a inclusão do óleo de soja somente alterou a concentração de γ-glutamil transferase (GGT) e creatinina. O tempo de treinamento físico tem efeito no condicionamento dos equinos, que melhora com a redução da concentração de lactato, e na concentração de glicose, que aumentou no teste de esforço físico.

The objective of this study was to the evaluate physiological, hematological and biochemical parameters of eventing horses fed diets containing soybean oil and submitted to physical effort tests. Twelve horses were used in a completely randomized design with two diets and six replications. The diets used were: diet without soybean oil inclusion (control) and diet with inclusion of 10% soybean oil. The experiment lasted 82 days, with three exercise tests: at the beginning, 60th and 82th day of the experiment. There were five data collections for each test: before the test with the horses at rest, immediately after the test, and at 10, 20 and 120 minutes after each test. Body temperature and rate heart were taken and blood samples were collected to evaluate hematological and biochemical variables.The mean values of the physiological, metalogical and biochemical parameters were submitted to non-parametric analysis.The inclusion of soybean oil only altered the γ-glutamyltransferase (GGT) and creatinine concentration in function time of intake of the diet. There was effect of trainings time on the horses conditioning that improved with reduction in the lactate concentration while the glucose concentration increased at the last exercise test.

Este trabalho teve como objetivo avaliar a capacidade tamponante (CT), o pH e a consistência das fezes em equinos submetidos à sobrecarga dietética com amido. Seis equinos adultos foram submetidos à sobrecarga com infusão gástrica de 17,6g de amido kg-1 de peso corporal através de sonda nasogástrica. Amostras fecais foram coletadas, antes e quatro, oito, 12, 16, 20, 24, 28, 32 e 36 horas pós-sobrecarga, e imediatamente submetidas à avaliação do pH, da CT e da consistência. Os resultados de pH foram comparados pelo teste t de student (P<0,05). Já os resultados da CT e consistência fecal foram comparados pelo teste de Kruskal-Wallis (P<0,05) e submetidos à análise de regressão e correlação de Spearman em função do tempo após a sobrecarga. Houve redução (P>0,05) no pH fecal ao longo de 36 horas pós-sobrecarga, com valores médios variando de 6,09 a 4,46. A partir do modelo pH = 6,083 - 0,003t - 0,001t² (R² = 0,634), houve decréscimo de 0,004 no pH fecal a cada hora, de 0,028 a cada quatro horas e de 1,404 ao final de 36 horas após a sobrecarga, respectivamente. Além do pH, houve redução (P<0,05) na CT das fezes, em função do tempo após a sobrecarga. Observou-se correlação positiva (r=0,65; P<0,0001) entre o pH e a CT das fezes. Todos os equinos apresentaram fezes de consistência normal (escore 3) até a oitava hora após a sobrecarga. Posteriormente, esses animais apresentaram redução na consistência fecal (P<0,05) até 36 horas. Os resultados demonstram que a sobrecarga dietética com amido promove redução na consistência fecal, na capacidade tampão e consequentemente no pH das fezes em equinos.

This study aimed to evaluate buffer capacity (BC), pH and faeces consistency of horses submitted to dietetic starch overload. Six crossbreed mature horses were submitted to starch overload with gastric infusion of 17.6g starch kg-1 body weight through nasogastric tube. Faecal samples were collected, before and at 4, 8, 12, 16, 20, 24, 28, 32 and 36 hours post-overload, and immediately submitted to evaluation of pH, BC and consistency. The pH data were compared by t student test (P<0.05). The BC and fecal consistency were compared by Kruskal-Wallis test (P<0.05) and submitted to regression analysis and Spearman correlation in function of the time after overload. There was faecal pH decreased along 36 hours post-overload (P>0.05), with means values varying from 6.09 to 4.46. Based on the model pH = 6.083 - 0.003t - 0.001t² (R² = 0.634), faecal pH decreased 0.004 per hour, 0.028 to each four hours and 1.404 at 36 hours after overload, respectively. As pH, faeces BC decreased (P<0.05) in function of the time after overload. Positive relationship was observed (r = 0.65; P<0.0001) between pH and BC of faeces. All horses presented normal consistency faeces (score 3) until eight hours after overload, following by reduction (P<0.05) up to 36 hours. Results demonstrated that starch overload reduce faecal consistency, buffer capacity and pH in horses faeces.
