Uso de probiótico e antibiótico sobre o desempenho, o rendimento e a qualidade de carcaça de frangos de corte

Dois mil e quatrocentos pintos de corte foram distribuídos em um delineamento inteiramente ao acaso, com esquema fatorial 2 x 2 x 2 (sexo, com e sem probiótico, com e sem antibiótico), totalizando oito tratamentos e seis repetições com 50 aves cada uma. Independente da suplementação recebida, os machos sempre foram mais pesados que as fêmeas. Entretanto, a análise de desempenho apresentou maiores peso corporal e ganho de peso para os machos que receberam suplementação de antibiótico, quando comparados aos não-suplementados. Até 42 dias de idade, o uso do antibiótico determinou aumento do consumo de ração, mas não influiu nas demais características de desempenho. No período de 1 a 21 dias e 1 a 42 dias de idade, a suplementação com probiótico influenciou negativamente o peso corporal, ganho de peso e consumo de ração das aves. Houve interação probiótico x antibiótico para rendimento de carcaça das aves, obtendo-se maior rendimento de carcaça com o uso da associação dos produtos na ração. Nenhum dos produtos afetou o rendimento de partes (cabeça, pés, asas, perna, peito e dorso), o rendimento de vísceras (coração, fígado e vísceras não-comestíveis), gordura abdominal e características sensoriais (intensidade de aroma, aroma estranho, sabor, sabor estranho, maciez, suculência, preferência, cor característica e aparência geral) da carne de peito e pernas. No presente estudo, não foram encontrados efeitos benéficos da suplementação de probiótico para frangos de corte.

Development of a novel fermented soymilk product with potential probiotic properties

The study was carried out to test the ability of Enterococcus faecium, Lactobacillus acidophilus, L. jugurti, Streptococcus thermophilus and L. delbrueckii ssp bulgaricus to decrease cholesterol in vitro and to grow in the presence of bile salts. Both properties were dependent on the species under study. The cultures were also inoculated into soymilk fortified with dry milk whey powder as single or mixed starters. The physicochemical and sensory evaluations of the fermented products showed that E. faecium plus L. jugurti (ratio 1:1) is the best combination, and this mixture also produces a 43% decrease in cholesterol. © Springer-Verlag 1999.

Efeito de um novo produto fermentado de soja sobre os lípides séricos de homens adultos normocolesterolêmicos

This study was undertaken to verify the effect of a daily intake of a new fermented soy milk produced with Enterococcus faecium and Lactobacillus jugurti on the serum lipid levels in normocholesterolemic middle-aged men. The study was randomized, double-blind and placebo-controlled and was performed for a period of 6 weeks. Forty-four normocholesterolemic healthy, male volunteers, aged 40-55 years old were randomly separated in two groups: The F-group received 200 ml of the fermented product daily and the P-group received 200 ml of placebo (chemically fermented). The blood samples were drawn initially and after 3 and 6 weeks and serum values for total cholesterol, HDL-cholesterol and triglyceride were determined. The LDL-cholesterol value was estimated. No significant changes in the fermented group (F) were observed for total cholesterol, LDL-cholesterol or triglyceride levels, while the HDL-cholesterol level was significantly higher (p≤ 0,05) after 6 weeks. The total cholesterol and LDL-cholesterol levels were significantly higer (p≤ 0,05) in the placebo group (P), but no changes were found for the HDL-cholestrol and triglyceride levels during the experimental period. In conclusion, the intake of 200 ml/day of the fermented soy milk, produced with E.faecium and L. jugurti, for 6 weeks, did not affect the serum total cholesterol and LDL-cholesterol, and led an increase of 10% in the HDL-cholesterol level.

Fermented soy product supplemented with isoflavones affected fat depots in juvenile rats

Objectives: This study investigated the effects of soy product fermented by Enterococcus faecium and Lactobacillus jugurti supplemented with isoflavones on adipose tissue, blood lipid, and glucose levels on juvenile rats. Methods: Rats were fed a cholesterol-enriched diet for 3 wk as a preliminary treatment to create hypercholesterolemia. They were then fed a chow diet (HC), a chow diet plus fermented soy product supplemented with isoflavones (HCFI), a chow diet plus placebo (HCP), or a chow diet plus placebo supplemented with isoflavones (HCPI), respectively, for an additional 3 wk. Results: The beneficial effects of fermented soy product supplemented with isoflavones on epididymal (EPI) and retroperitoneal (RET) fat pads was likely due to isoflavones because adipocyte circumference (micrometers) in the HC group was significantly larger (EPI: 105.66 ± 13.36; RET: 134.95 ± 25.40) than that in the HCFI group (EPI: 93.17 ± 12.80; RET: 108.62 ± 15.50) and HCPI group (EPI: 93.06 ± 15.10; RET: 112.34 ± 18.21). The probiotic micro-organism accentuated the antilipogenic effect of isoflavones on RET (HCFI: 108.62 ± 15.50 micrometers versus HCPI: 112.34 ± 18.21 micrometers). Moreover, the fermented product increased glucose concentration similar to that in the chow group but did not change blood lipids. Conclusion: This product may offer new approaches to obesity prevention. © 2005 Elsevier Inc. All rights reserved.

Uso de probióticos em ração de rã-touro (Rana catesbeiana): Desempenho produtivo

This experiment had as objective to evaluate the effect of two probiotics, added in the commercial ration (40% PB) on the productive performance of bullfrog Rana catesbeiana. The test was lead with two dosages of each probiotic (5 g/kg of food and 10 g/kg of food), plus a control group, with three repetitions, totalizing five treatments. The weight gain, the feed conversion (CA) and the specific growth rate (TCE) have been analyzed. The results show that the probiotics affect the weight gain of Rana catesbeiana until reaching 200 g, thus decreasing the time of productivity in 28 days but not improving the CA and the TCE. With bases in these experimental conditions probiotic 1 (Lactobacillus acidofillus, Bifidobacterium bifidum and Enterococcus faecium -3×10 6 UFC/g) at lower dose (5 g/kg of ration) provided the best performance of the animals.

Optimization of a synbiotic formulation of soy yoghurt containing yacon extract by response surface methodology

A synbiotic yoghurt based on a combination of soymilk and yacon water extract (from yacon root tubers) was developed as a novel food product fermented with a probiotic culture of Enterococcus faecium CRL 183 and Lactobacillus helveticus ssp jugurti 4l6. Response surface methodology (RSM) was used to optimize the independent variables soymilk protein concentration and percentage of yacon extract in the formulation through a Central Composite Rotatable Design (CCRD), consisting of a 22 factorial design with two levels (-1, +1), two central points (0) and four axial points (± a, 0) (0, ± α). The responses were assessed by consumer acceptance tests. The optimization indicated that a formulation with a soymilk protein concentration of 1.74g/L and 25.86% of yacon extract gave the best average values, 5.91 for the taste and 6.00 for the overall impression responses. The formulation with 40% of yacon extract and the same concentration of soymilk protein achieved similar acceptance values: taste (5.94) and overall impression (5.87), however, with the extra yacon, it probably had a greater content of prebiotic fructooligosaccharides. Consequently, both formulations may give useful functional foods, with sensory properties comparable with those of soy yoghurt (control formulation).

Small hospitals matter: insights from the emergence and spread of vancomycin-resistant enterococci in 2 public hospitals in inner Brazil

Although vancomycin-resistant enterococci (VRE) are reported in Brazil since 1996, data on their impact over settings of different complexity are scarce. We performed a study aimed at identifying determinants ofVRE emergence and spread in a public hospital consortium (comprising 2 hospitals, with 318 and 57 beds) in inner Brazil. Molecular typing and case-control studies (addressing predictors of acquisition or clonality) were performed. Among 122 authocthonous isolates, 106 were Enterococcus faecium (22 clones), and 16, Enterococcus faecalis (5 clones). Incidence was greater in the small-sized hospital, and a previous admission to this hospital was associated with greater risk of VRE colonization or infection during admission to the larger one. Overall risk factors included comorbidities, procedures, and antimicrobials (piperacillin-tazobactam, cefepime, and imipenem). Risk factors varied among different hospitals, species, and clones. Our findings demonstrate that VRE can spread within low-complexity facilities and from these to larger hospitals. (C) 2015 Elsevier Inc. All rights reserved.
