Efeito do período de jejum na fase final de criação de frangos de corte machos sobre desempenho e mortalidade

The objective of this work was to evaluate effect of fasting period in the last growing phase on performance and mortality of male broilers. Two thousand one-day old male chicks were distributed in five randomized blocks according to a 4x2 factorial. (Four feeding programs (FP): ad libitum or one of three fasting schedules: 8-12, 12-16 and 8-16; and two strains (S): Ross or Hubbard-Peterson). Fifty birds were used per replicate. Birds were raised under identical feed and management conditions until day 42. During the experimental period (days 43-56), average temperature, relative humidity and temperature-humidity index (THI) recorded at day and at night were 29.4°C, 57.7 % and 78.1; and 22.0°C, 73.1% and 67.4, respectively. No SxP interaction was observed for all characteristics studied. At day 56, the Ross broilers showed higher mean weight (3104 g), weight gain, WG (3059 g), feed/ gain ratio, FC (2.22) and production factor, PF (213), than the Hubbard-Peterson birds (3011, 2967, 2.28 and 194, respectively). During the experimental period, the Ross broilers showed higher WG (831 g) and FC (3.40) than the Hubbard-Peterson ones (770 and 3.67, respectively). Birds submitted to the 8-12 h fast showed higher feed intake (2864 g) than those that fasted during the 8-16 period (2690). No effect of P on mortality was observed, either considering the overall period (days 1-56) or the experimental period (days 43-56). Fasting in the last phase of rearing not aided by other practices failed to decrease heat stress effects on performance and mortality of male broilers.

Uso da restrição alimentar quantitativa para diminuir a mortalidade de frangos de corte machos

The effect of feed restriction (0, 10, 20, 30, 40 and 50%) from 8 until 14 days post-hatching on performance, total mortality incidence and sudden death syndrome (SDS) rate was studied in male broilers during winter and summer.Ad libitum fed broilers had a better performance, but a higher total mortality rate (13.00% in winter, 3.67% in summer) and SDS (3.67% in winter, 0.67% in summer). All restricted groups had a lower mortality level in winter than the control group with a non linear response influenced by feed restriction. Birds submitted to 40% feed restriction showed the lowest mortality incidence (2.67%) followed by groups submitted to 30% (4.67%), 50% (5.33%) and 10% and 20% (7.67%) feed restriction. Birds fed ad libitum had the highest SDS incidence (3.67%, against .33, 1.00, .67, 1.33 and 1.33% at 10, 20, 30, 40, 50% feed restriction, respectively), but differences were not significant. In summer, incidences of total mortality and due to SDS were low and not influenced by feed restriction, either during the restrictive period itself (8 to 14 days) or during the total period of raising (1 to 49 days). In both seasons, the feed restricted birds showed compensatory gain only until three weeks post-restriction period. At 49 days, body weight and weight-gain were lower in feed restricted birds, but feed :gain ratio rate was improved. This resulted in better productivity index in winter, but not in summer. The feed restriction at 30 to 40% for seven days during the second week may decrease mortality in male broilers raised in winter without lowering productivity if the restriction is followed by at least three weeks of full feeding.

Mortalidade por causas externas no Município de São José do Rio Preto, no período de 1996-1998

Introduction: An epidemiological study of the mortality rates by injuries in São José do Rio Preto, State of São Paulo, Brazil, has been carried out. The period considered is 1996-1998. Objectives: To show injuries mortality rates in São José do Rio Preto-SP in 1996-98. Methods: The study was based on official data from the Mortality Information Service of the Brazilian Ministry of Health, and in a survey based on data from medical forensic examiners (IML). Software Epinfo6.0 and Tabwin was utilized for data analises. Results: The results were compared to values obtained in the literature for the other cities of São Paulo and Brazil. In the case of São José do Rio Preto, was observed a decrease in the number of deaths associated with external causes in the period, but particularly in deaths due to traffic accidents with motor vehicles an increase in cases of pedestrians killed by hit-and-run drivers, that is much larger than the corresponding values for Brazil and for the State of São Paulo. The study showed increase in rates of homicides, mainly in the 15 to 39 years age group. Conclusion: This result suggests that is important to start programs to reduce the number of deaths by injuries, as well as the necessity of monitoring locally all these data.

Mortalidade e prognóstico específico em pacientes com insuficiência renal aguda

A variety of systems of risk factor stratification have been studied to predict the outcome in acute renal failure (ARF). OBJECTIVES. Assess and compare mortality and the Acute Tubular Necrosis Individual Severity Score (ATN-ISS) in patients with AFR treated in a university hospital. METHODS. A prospective analysis was made of 103 patients with a diagnosis of intrinsic ARF admitted to the Hospital das Clinicas da Faculdade de Medicina de Botucatu, UNESP. Patients were followed up until recovery of renal function or death. The Score ATN-ISS was recorded during the first hours of the assessment by a nephrologist. Results were reported as median or mean ± SD, with statistical significance of p<0.05. RESULTS. Fifty-one percent of patients were male with a mean age of 58 ± 36 years. Forty-four percent died in the hospital. Mortality was higher in patients from the surgical wards (52.7%) and in patients who were treated with dialysis (63.8%). The score ATN-ISS showed a good confidence level, with high discriminatory power (area under the curve of 0.95) and good accuracy. CONCLUSIONS. Mortality in this study was comparable to that found in literature. The ATN-ISS was shown to be a prognostic index with a high confidence level that could be routinely applied by nephrologists to patients with AFR.

Intervenções benéficas no pré-natal para prevenção da mortalidade materna

Maternal mortality rate (MM) is a health quality indicator that is directly influenced by the economic, cultural and technological level of a country. Official data of MM in Brazil, although underestimated, point to the lack of quality in pregnancy, childbirth and puerperium care services. This characteristic is common in developing countries, where poorer pregnant women as well as those facing greater difficulty to quality care access are found. Prenatal care cannot prevent major childbirth complications, which are important causes of MM; however, some interventions during the prenatal period can favor maternal prognosis and prevent MM. In this setting, this study brings a scientifically based update concerning effective interventions for maternal mortality prevention during the prenatal period. The most important strategies consist of a tripod with specific interventions related to maternal health promotion, risk prevention and assurance of nutritional support during gestation, in addition to criteria to investigate gestational risk and inclusion of the pregnant woman in the basic component of the prenatal care model. It ends with the definition of priorities in the prevention of MM related to eclampsia/preeclampsia and reinforces the importance of normalization of reference systems for obstetric emergency cases.

Índice de infestação e fatores de mortalidade do bicudo-do-algodoeiro (Coleoptera: Curculionidae) no semi-árido do sudoeste da Bahia, Brasil

The boll weevil (Anthonomus grandis Boheman, 1843) (Coleoptera: Curculionidae) is a pest that limits the production of cotton, especially in the North East of Brazil. The present study aimed to estimate the infestation index and natural mortality of boll weevil at Caraibas County, located in the semi-arid of the Southwest ofBahia. The experiment was performed using the cultivar BSR Aroeira, at Fazenda Lagoa Seca, in 2006. Weekly evaluations were performed, in five sampling areas 25m2, collecting blossoms fallen on the ground. The infestation was estimated by counting the oviposition punctures and /or the feeding on blossoms, and also by the presence of one of the phases of the boll weevil in the inside. Mortality factors were studied through the dissection of blossoms, estimating predation, parasitism, dissection and disease. The results obtained allowed to conclude that the boll weevil determines high infestation levels in the region. Parasitism, dissection and predation, following this order, determine high rates of real mortality of the pest. Catolaccus grandis Burks, 1954 (Hymenoptera: Pteromalidae) and Bracon sp.(Hymenoptera: Braconidae) are parasitoids of boll weevil reported in sothwestern Bahia, being the first one the predominant species. © 2009, Sociedad Venezolana de Entomología.

Coeficiente de operación de un sistema formado por un refrigerador doméstico acoplado a un acumulador de agua caliente para la recuperación de energía

An experimental apparatus containing a domestic refrigerator coupled to a vertical hot water storage tank was used for energy recovery. The original condenser of the refrigerator was maintained, but modified with a concentric tubes heat exchanger with countercurrent water and refrigerating gas flows. The coefficient of performance for the heat pump is calculated by the ratio of energy in the heat storage and the electric power consumed by the domestic refrigerator compressor. The results show that the increasing of hydrostatic pressure in the storage tank increases the water flow rate and the coefficient of performance. The proposed device also reduces the heat dissipation to the surroundings. This is more important in small confinements found in low-cost houses.

Necessidade Hídrica E Coeficiente de Cultivo do Pimentão Fertirrigado

This study aimed to determine the crop evapotranspiration (ETc) and crop coefficient (Kc) of fertigated sweet pepper, measured over time (15, 30, 45, 60, 75, 90 and 105 days after the transplant). The experiment was conducted on a battery of 40 drainage lysimeters, arranged in a 8 x 5 matrix, in the period October/2009 to January/2010, located in the Federal Rural University of Pernambuco (UFRPE) Campus in Recife, in a completely randomized factorial scheme 5 x 2, with four replications, being five irrigation depths (80, 90, 100, 110 and 120% of ETc) and two levels of potassium (80 and 120 kg K2O ha-1) where the experimental plot was composed of three plants in each lysimeter. The Mauchly Sphericity Test indicated multivariate variance analysis for the studied variables ETc (mm d-1) and Kc, the variables presented adjustment under quadratic effect of variation on observation times, when the irrigation depths were fixed, and descending linear adjustments under the variation of irrigation depths effect, when the times of observation were fixed in each potassium dose.
