Abstract: Este experimento foi conduzido para avaliar níveis de treonina total em ra es para leitoas dos 30 aos 60 kg. Quarenta fêmeas, com peso inicial médio de 29,2 ± 1,4 kg, foram utilizadas em delineamento experimental em blocos casualizados, com cinco tratamentos (0,60; 0,65; 0,70; 0,75; e 0,80% de treonina total), quatro repeti es e dois animais por unidade experimental. A ra o basal com 18% de proteína bruta e 0,928% de lisina total, atendeu as exigências das leitoas, de acordo com o NRC (1988), exceto de treonina. A ra o basal foi suplementada com L-treonina, resultando em ra es experimentais que proporcionaram rela es treonina digestível:lisina digestível calculadas de 62, 68, 74, 80 e 86%, respectivamente. Ao final do experimento, quando os animais atingiram peso médio de 59,98 ± 2,9 kg, foram coletadas amostras de sangue, para análise de uréia no soro sangüíneo, e um animal por unidade experimental foi abatido para avaliar a taxa de deposi o de proteína na carca a. Observou-se efeito dos níveis de treonina sobre o ganho de peso dos animais, que aumentou de forma linear. O consumo de ra o aumentou quadraticamente até o nível de 0,66% de treonina da ra o. Os tratamentos influenciaram a convers o alimentar (CA), que reduziu até o nível de 0,70%. A rela o estimada da treonina digestível:lisina digestível verdadeira, no nível que proporcionou os melhores resultados de convers o alimentar, correspondeu a 75%. N o foi observado efeito dos tratamentos sobre o teor de uréia no soro sangüíneo. Os níveis de treonina também influenciaram a taxa de deposi o de proteína na carca a, que aumentou de forma quadrática até o nível de 0,70%. Concluiu-se que leitoas com alto potencial genético dos 30 aos 60 kg exigem 0,70% de treonina total, correspondente a 0,62% de treonina digestível, e a uma rela o estimada treonina digestível:lisina digestível verdadeira de 75%.

Abstract: Foram utilizados 75 suínos com peso inicial médio de 5,8 ± 0,4 kg, com o objetivo de avaliar níveis de treonina em ra es para leit es com alto potencial genético para deposi o de carne magra dos 6 aos 15 kg. Foi usado o delineamento experimental de blocos ao acaso com cinco tratamentos (níveis de treonina), cinco repeti es e três animais por unidade experimental. Os tratamentos corresponderam a uma ra o basal com 18% PB e 1,108% lisina total, suplementada com cinco níveis de L-treonina, resultando em dietas com níveis de 0,682; 0,732; 0,782; 0,832; e 0,883% de treonina total. Observou-se varia o quadrática para ganho de peso diário (GDP), que aumentou até o nível de 0,77%, e para consumo de ra o (CR), que aumentou até o nível estimado de 0,73%. Os níveis de treonina também influenciaram de forma quadrática a convers o alimentar (CA), que melhorou até o nível de 0,82%. A rela o da lisina digestível verdadeira:treonina digestível verdadeira, no nível que proporcionou os melhores resultados de CA, correspondeu a 100:73. Concluiu-se que leit es com alto potencial genético para carne magra dos 6 aos 15 kg exigem 0,77% de treonina total na ra o para máximo ganho de peso e 0,82% para melhor convers o alimentar.

Abstract: in performance and metabolism trials, diets with reduced levels of crude protein, calcium and available phosphorus on the performance, carcass characteristics, tibia ashes, balance and retention of nitrogen and phosphorus of broiler chickens in phase from 8 to 21 and 8 to 35 days were evaluated. in each phase, 30 and 25 birds per experimental unit were used in the performance assay and five and three in the metabolism assay, respectively, in a completely randomized experimental design, with six replications. treatments consisted of diet with 21% crude protein without phytase (control), formulated with nutritional levels recommended on the brazilian tables, and diets with 21, 20, 19 and 18% crude protein with phytase (8 to 21 days) and from 8 to 35 days, the control diet had 20% crude protein without phytase (control), and others diets with 20, 19, 18, 17% crude protein, with phytase. in the diets with phytase (80 g of ronozyme np(m) phytase per ton of diet), the level of available phosphorus was reduced in 0.15 and the calcium in 0.30 percentage points in relation to the control diet. no effect was observed with the reduction of nutrients on feed intake, weight gain, or feed conversion in either phase or for the study of carcass characteristics to the 35 days. however, higher abdominal fat percentage was observed when the broilers were fed diet with lower protein level. the excretion of nitrogen and phosphorus decreased when birds received diets with reduced levels of these nutrients. ash percentage in the tibia was not influenced by treatments. it is possible to reduce protein level, available phosphorus, and calcium of the diets in up to 3, 0.15 and 0.30 percentage points when the diets are supplemented with phytase and amino acids, respectively.

Abstract: twenty-four holstein crossbred young bulls, with 75 kg initial average weight and 215 kg final average weight, were confined in a feedlot. the objective of this experiment was to evaluate the production cost. the animals were fed elephant grass with 30 to 45 days of age, soybean meal, corn meal, meat meal and mineral mix basal concentrate, and broiler litter, which constituted the treatments: 1 = 50% forage and 50% concentrate, 2 = 50% forage, 35% concentrate and 15% broiler litter, 3 = 25% forage and 75% concentrate and 4 = 25% forage, 52.5% concentrate and 22.5% broiler litter, as dry matter basis. it was used the completely randomized blocks experimental design, with six blocks and four treatments. the gross income, costs and profit analysis indicated that the profit was negative in all treatments when the produced meat sale price was the same as the fat ox price. however, when the same costs were maintained (effective operational cost and total operational cost) and the kilo of produced meat sale price rose 10%, relative to the fat ox kilo of meat price, all the treatments presented profit, distinguishing the treatments 2 and 3, with r$ 0.042 and r$ 0.03 per kilo of produced meat and return on the invested capital of 14.20 and 14.64%/year, respectively. the concentrate price variation, from 0.26 to 0.20 r$/kg, caused larger impact in the effective operational cost of treatment 3 and smaller in treatment 2, providing profit and return on the invested capital for all treatments, based on the 7.62:1 relationship between concentrate price x meat price. the simulations showed that treatment 2 was economically more advantageous because it produced a better cost/benefit relationship in the conditions of the present work.

Abstract: Being able to predict the prognosis of a patient with acute pancreatitis at admission forms a very important strategy considering that this will enable us to practice guidelines for standardization of management of the patient, viz., the use of antibiotics, timings of computed tomography scans, use of ERCP and operative intervention. This will in turn translate into improved outcomes [1]. Data on the use of scoring systems in India and Asia, as a whole, are sparse. The aim of this study was to compare the accuracy of APACHE II and Imrie scoring systems in assessing severity of acute pancreatitis.All patients who presented to a tertiary care referral centre with a diagnosis of acute pancreatitis between June 2003 and January 2005 were prospectively evaluated.The diagnostic criteria used for acute pancreatitis included:1) Clinical criteria – history of pain in abdomen radiating to the back and relieved on bending forward associated with tenderness/guarding in the upper abdomen.2) Radiographic evidence – Computed Tomography findings suggestive of acute pancreatitis such as pancreatic edema, pancreatic necrosis, peripancreatic fluid collections3) Biochemical – Serum amylase concentration greater than 180 Somogyii units (by the Somogyii method).The Atlanta Consensus definitions of severe and mild disease were used [2]. Acute pancreatitis was classified as severe if the patient had associated organ failure and/or local complications such as necrosis, abscess, or pseudocyst. The episode was also labeled severe if the patient required surgical intervention. If the episode was associated with minimal organ dysfunction and uneventful recovery without the features considered under severe acute pancreatitis, it was deemed to be mild.Presentation data on admission and at 48 hours were collected. Acute Physiology and Chronic Health Evaluation (APACHE) II and Imrie scores were calculated within the first 48 hours of admission.The APACHE II scoring system as proposed by Knaus et al
