Cobertura populacional do Sistema de Vigilância Alimentar e Nutricional no Estado de São Paulo, Brasil

O objetivo deste artigo é estimar a cobertura populacional do Sistema de Vigilância Alimentar e Nutricional (SISVAN) nos diferentes estágios de vida e avaliar seu funcionamento no estado de São Paulo. O estudo incluiu 65 municípios divididos em 14 regiões do estado. A cobertura do SISVAN foi estimada a partir de dados de monitoramento do estado nutricional disponíveis nos relatórios públicos, e do número de usuários que frequentam os serviços públicos de saúde. O total de usuários foi obtido pela diferença entre o total de habitantes e o número de beneficiários de planos de saúde privados. A maioria das regiões apresentou uma cobertura reduzida (<10%). Cerca de 57% revelaram cobertura entre 5 e 10%. Constatou-se uma preponderância de registros do estado nutricional de crianças para todas as regiões do Estado. Chama a atenção a reduzida cobertura entre os idosos, que é inexistente ou próxima de zero na maioria das regiões. Apesar dos esforços empreendidos pelo governo visando à ampliação e à qualificação do SISVAN, o monitoramento nutricional no estado de São Paulo ainda é insuficiente. Esta condição compromete sua utilização na elaboração de políticas efetivas na área de alimentação e nutrição.

Carotenogênese em células de Haematococcus pluvialis induzidas pelos estresses luminoso e nutricional

The objective of this work was to evaluate the responses of Haematococcus pluvialis cells to the carotenogenesis induction process, under light and nutrition stress. Cells were acclimated during 15 days in WC medium, with aeration with synthetic, filtered atmospheric air and flow rate of 100 mL min-1, light intensity of 50 µmol photons m-2 s-1, photoperiod of 12 hours, and temperature of 23ºC. The following two treatments were compared: cultivation under the described conditions, but with increase of light intensity up to 350 µmol photons m-2 s-1 ; and cultivation under the same conditions as the previous treatment, but with aeration containing 4% CO2. The treatments were done in triplicate, during ten days. With the addition of CO2 and the increment in lighting, an increase was observed in the carotenoids/chlorophyll ratio and cell biomass. Cells stopped dividing on the second day of stress, when nitrate became limiting, and significantly increased their biovolume. The excretion of organic carbon and the concentration of astaxanthin increase in response to the addition of CO2. Stress by light intensity combined with CO2 addition optimizes carotenogenesis in H. pluvialis and increases astaxanthin production.

Efeitos da omissão de nutrientes em plantas de Caesalpinia echinata

The objective of this study was to evaluate the growth, the morphological alterations and the mineral composition of brazilwood (Caesalpinia echinata) plants caused by mineral nutrients omission in a green house experiment. The experimental units were distributed in the green house according to a completely random design. The treatments, each repeated five times, were the following : check (natural soil), complete (N, P, K, Ca, Mg, S, B, Cu, Mn, and Zn) and a complete solution but for the omission of one of the nutrients in parenthesis. Each plot was represented by a plant growing in a 7 dm3 vase filled with Quartzarenic Neosol. The analyzed variables were the following: visual nutritional deficiency symptoms, plant height, stem diameter, shoot dry matter, stem, branches and leaves included, and leaf nutrients level. The omission of nitrogen limited plant growth in height and shoot biomass production. The first visual deficiency symptoms were those due to N omission followed by those caused by P, Ca, Mg, S, Cu, and Mn omissions. Later on the K and B deficiency symptoms became visible. The omission of a nutrient always caused its level in the leaves to be significantly lower than that found when it was not omitted.

A procedure to evaluate the efficiency of utilization of dietary amino acid for poultry

The aim of this study was to develop a procedure based on Gompertz function to determine the efficiency of utilization of amino acid. The procedure was applied to determine the efficiency of utilization of dietary lysine, methionine+cystine and threonine by growing pullets and based on the efficiencies were estimated the requirements for the growth phase of birds. The Gompertz function was fitted to the data of feed intake, body weight, feather-free body protein weight and feather protein weight of four strains of laying hens in the growth phase. The rates of consumption and daily protein deposition (PD) were calculated. The amino acid deposition was obtained by multiplying the PD by the amino acid concentration in feather protein and feather-free body protein. The results showed that the efficiency of utilization of amino acid decreased with maturity and, conversely, there was a proportional increase of the requirement per kg of weight gain. The procedure based on the Gompertz function to determine the efficiency of utilization of amino acid proved to be suitable to evaluate the efficiency of utilization of amino acid and can be a useful tool to diagnose the effectiveness of the nutritional management, aiding in decision-making on the nutritional management.

Avaliação nutricional do feno das folhas da amoreira (Morus alba L.) em frangos de corte

The trial was carried to evaluate the nutritional effects of mulberry leaf hay in broiler chickens. Five treatments were used: control (no mulberry, 3.16% CF); 15% mulberry (4.14% CF); 30% mulberry (5.09% CF), no mulberry (4.14% CF); no mulberry (5.09% CF). A randomized blocks design was used, with two blocks and three replications into the blocks to evaluate performance index, histopathological examination of the visceral organs and morphometric measurements of the hepatocyte nucleus and pancreatic acini. A poor performance index was observed for broilers feeding on mulberry leaves; lesions such as steatosis, proliferation of hepatic duct cells and multiple necrosis were found in the livers of the chickens fed with 30% mulberry (5.09% CF), as well as size reduction of the hepatocyte nucleus and pancreatic acini. From these data, it is concluded that mulberry probably has some toxic substance which can interfere in the improvement of diet ingredients, resulting in damage to broiler chickens.

Nutritional balance and yield for green manure orange trees

Intercropping could efficiently prevent soil nutrient losses caused by extensive agriculture. The present study aimed to assess the effect of green manure on the nutritional status of orange trees cultivar 'Pera' (Citrus sinensis (L.) Osbeck). The plants were grafted on 'Cravo' lime trees and were then planted in a 7x4m space. Four different treatments corresponding to the evaluated green manures were employed: jack bean (JB) (Canavalia ensiformis DC), lablab (LL) (Dolichos lablab L.), pigeon pea (PP) (Cajanus cajan L. Millsp), and Brachiaria (BQ) (Brachiaria brizantha Hochst ex A. Rich. Stapf) as control. The experimental design was in randomized blocks, in split-plot time, with six replicates, with four treatments (green manures) and two plants per evaluation. The nutritional status was assessed by using the DRIS method (Diagnosis and Recommendation Integrated System); the yield and the macro and micronutrient levels contained in green manures and in the control was also determined. The nutritional diagnosis indicated that, in the two years of experiment, plants treated with green manure showed better nutritional balance index compared to Brachiaria. This suggests that, over time, green manure can lead to better nutritional balance. Pigeon pea treatment showed the highest yields, compared to control, in the two evaluated crop cycles (2004/05 and 2005/06).
