Efeito de extratos de própolis verde sobre bactérias patogênicas isoladas do leite de vacas com mastite
PINTO, Marcelo Souza;FARIA, José Eurico de;MESSAGE, Dejair;CASSINI, Sérvio Túlio Alves;PEREIRA, Carmen Silva;GIOSO, Marilú Martins;
Brazilian Journal of Veterinary Research and Animal Science , 2001, DOI: 10.1590/S1413-95962001000600006
Abstract: in vitro, the sensitivity to different propolis extracts, at a concentration of 100 mg/ml, of staphylococcus aureus, staphylococcus sp. coagulase negative, streptococcus agalactiae and bacteria of the coliform group, isolated from the milk of cows with mastitis, was evaluated using the technique of an agar disk diffusion with a medium doublelayer. the results showed that the commercial propolis, the ethanolic extract, and, in a minor proportion, the methanolic extract inhibited the growth of the gram positive bacteria, staphylococcus aureus, staphylococcus sp. coagulase negative and streptococcus agalactiae. the extracts obtained through water, etila acetate and chloroform did not inhibit any bacterial strains, nor did the pure ethanol and methanol vehicles that were utilized as controls. the gram negative bacterium tested, from the coliform group, did not show sensitivity to any extract. bacterial strains of the same species collected from different sources presented significant differences in sensitivity to the extracts (p < 0.05). in the streptococcus agalactiae samples, the diameters of the zone of inhibition around the disks were bigger than those observed for samples of staphylococcus aureus and staphylococcus sp. coagulase negative. the results of this experiment stimulate the continuation of studies on the use of propolis extracts, by means of using the appropriate vehicles for the treatment of bovine mastitis.
Strategic Fast Supply Demand-Chains in a Network Context: Opportunistic Practices That Can Destroy Supply Chain Systems  [PDF]
José Crespo de Carvalho, Ana Lúcia Martins, Tania Ramos, Eurico Brilhante Dias
American Journal of Industrial and Business Management (AJIBM) , 2014, DOI: 10.4236/ajibm.2014.43019
Abstract:

This paper has a conceptual character and explores an approach between transaction cost analysis theory and network theory when applied to supply chains in a broader context: industrial management research. This approach raises the assumptions that fast supply chains, i.e., supply chains made of short time relationships and multiple partners can contribute to destroying trust and collaboration between companies, ending up by stressing actual systems’ arrangements in somehow stable supply chains/network chains. As a consequence, transforming them in distrust arrangements and thus giving birth to new (old) approaches based only on transaction cost analysis theory: opportunism and limited rationality as the continuum for relationships between companies in a globalized world with numerous potential agents/companies that can play several roles. Too high levels of entropy can show this reality: the number of potential players (suppliers, customers or complementors) with theoretically equal probability of establishing partnerships with one focal company in a supply chain or network arrangement is excessive in relation to the number of current suppliers, customers and complementors, and for that reason, the focal company is somehow dissipating energy in identifying several potential players and in a state of giving one way or another equal importance to them all, situation that can affect stable relations with current partners. Theoretically, this will create what looks like strategic fast supply—demand chains or network chains: fast because they are rapidly settle down and fast as they are also rapidly dismantled. Those arrangements are the ones responsible for several possible and fast relations (internalizing resources from the environment and/or externalizing resources to the environment) but, anyway, contributing to loose trust, credibility and running against profitable games with partners already involved with focal companies in stable supply chains.

Abstract: the search for balanced diets, which may elicit improved growth of fish, requires appropriate selection of available protein sources. this study aims at clustering feedstuffs according to amino acid profile, determining which ones show essential amino acids (eaa) profiles closer to the ideal dietary amino acids requirements of nile tilapia (oreochromis niloticus), and studying the relationship among amino acids feedstuffs groups. tabled data on eaa more cystine and tyrosine, in relation to lysine contents, of 40 feedstuffs ordinarily used to formulate fish diets were studied. feedstuffs were grouped according to amino acids profile by cluster analysis of euclidean distances. the principal components analysis was used to determine the relationship among amino acids in each feedstuff group. three groups of ingredients were parted and two ingredients, low tannin sorghum and corn gluten meal 60%, did not go with any group. dietary amino acids requirements of nile tilapia were similar to the amino acid profile of 22 feedstuffs. the principal component analysis explained with three principal components more than 75% of total variance of amino acids in three feedstuff groups. therefore, until additional, detailed information on amino acids availability of different ingredients is consolidated, total amino acids profiles will continue to be important information to select and use conventional or surrogate ingredients for formulating and processing feeds for tilapia.

Abstract: adding attractants can improve acceptability of artificial diets by carnivorous fish fry and fingerlings, increasing intake of unpalatable feeds and improving growth rate, while reducing feeding time and feeding wastes. this study aimed to evaluate the effects of levels of inclusion of different attractants in plant protein-based diets on the performance of largemouth bass micropterus salmoides. nine hundred juvenile largemouth bass (26.54 ± 1.53 g) conditioned to accept dry, artificial feed were stocked in 60, 90-l polyethylene tanks (15 fish per group) in a completely randomized design trial (n=3). fish were fed two daily meals ad libitum at 7h00 and 17h00, for 13 days, with a diet (100% plant protein source) containing either soluble fish protein - sfp (0.5, 1.0, 1.5, 2.0, 2.5, and 3.0%); fisharontm - fa (0.02, 0.04, 0.06, 0.08, 0.10, 0.12%); fish silage - fs (1.0, 2.0, 3.0, 4.0, 5.0, and 6.0%); a positive control diet - pcd (10% fish meal) and a negative control diet - ncd (basal diet without attractants). dl-methionine (98%) and l-lysine (80%) were added automatically by the formulation software to adjust available amino-acid profile of diets. recorded performance data were: final weight, feed intake, weight gain and feed conversion ratio. fish fed diet fa0.02 presented the best growth rate, best weight gain and best feed conversion ratio. fish fed diets containing fs as attractant presented the poorest performance.

Abstract: two trials were set up to evaluate the influence of different levels of dietary vitamin c supplementation on growth, performance, survival rate and resistance to low dissolved oxygen (lodo) concentration of piau?u fingerlings (leporinus obtusidens). trial 1 (105 days) evaluated the effect of diet supplementation with l-ascorbic acid (0, 50, 150, 250, 350, 450, 550, 650, 750, 850 mg of vitamin c/kg of diet) on weight gain and survival, in a completely randomized design. there was no significant differences among treatments with respect to weight gain (p > 0.4054) and survival rate (p > 0.5657). in trial 2, groups of 10 fish of each replicate of trial 1, were stocked in 20-l cages, in a randomized block design, and submitted to a 14-h lodo stress (1.0 mg do/l). fingerling survival rate was not significantly affected by lodo levels (p > 0.4032) up to 14 hours after stressing conditions ceased. in contrast to our results, data found in the literature show that dietary vitamin c supplementation significantly affects the studied parameters. therefore, it is suggested that more extensive studies should be performed to determine dietary vitamin c requirements of this species.

Abstract: O experimento teve como objetivo avaliar a influência da suplementa o de vitamina C na dieta sobre o desempenho de alevinos de piau u (Leporinus obtusidens). Um primeiro ensaio (105 dias) testou o efeito da suplementa o de níveis crescentes de L-ácido ascórbico (0, 50, 150, 250, 350, 450, 550, 650, 750 e 850 mg/kg) na dieta sobre ganho de peso e sobrevivência, num delineamento inteiramente ao acaso. N o houve diferen as significativas (P > 0,4054) entre os tratamentos, tanto para ganho de peso como sobrevivência. Num segundo ensaio avaliou-se a influência da vitamina C na resistência dos alevinos à hipoxia. Grupos de dez peixes aleatoriamente selecionados de cada tratamento do primeiro ensaio foram estocados em gaiolas, num delineamento em blocos ao acaso. A suplementa o com vitamina C na dieta n o afetou (P > 0,4032) a sobrevivência dos alevinos submetidos a hipoxia (oxigênio dissolvido abaixo de 1,0 mg/L) por até 14 horas. Contrariamente aos nossos resultados, a literatura mostra que a suplementa o dietética com ácido ascórbico tem efeito benéfico, nos parametros avaliados, nas várias espécies de peixes. Assim, sugerimos que novos estudos sejam realizados no sentido de se definir o nível de suplementa o de vitamina C em dietas para alevinos de piau u.
