This study investigates the effect of citral on growth and occurrence sublethal damage in Listeria innocua Serovar 6a (CECT 910) monocytogenes 4b 4032) cells that were exposed to as a natural antimicrobial agent. Two initial inoculum concentrations considered this investigation: 102 106 cfu/mL. Citral exhibited antilisterial activity against L. monocytogenes, observed effects dependent concentration present culture medium (0, 0.150 0.250 μL/mL) (p ≤ 0.05). had shorter lag phase than two...
In the first trial a total of 250 day-old male chicks were distributed into five treatments and given following diets: diet with growth promoter; without added avilamycin only; supplemented 0.5g oregano oil kg diet-1; 1.0g diet-1. other 288 was used four treatments, which anticoccidial agent; nonmedicated group had highest crypt depth differs from chickens fed promoter or 0.5 The broilers positive control (antibiotic anticoccidial) villous: ratio compared negative that lowest villous:crypt...
The essential oil of Schinus terebinthifolius (Anacardiaceae) was analyzed by GC and GC-MS. α-Fenchene, limonene, β-pinene, α-phellandrene, β-isosylvestrene represent about 80% the composition. reproductive toxicity in Wistar male rats evaluated. No changes were observed mass organs, number morphology spermatozoa, rates, body offspring after treatment with S. terebinthifolius.
Three hundred and twenty 30-week old White Leghorn cockerels were housed in individual cages distributed a completely randomized factorial design of 5 × 3, with five oil sources (sunflower, soybean, canola, linseed fish/soybean) three levels antioxidant (30, 200 400 mg vitamin E/kg). The aim this study was to evaluate the effect ratio ω6 : ω3 fatty acids by inclusion different dietary supplementation E on reproductive performance cockerels. use fish/soybean combination determined lowest...
1. A 3-week feeding trial with 96 sexed d-old broiler chickens was conducted to examine the effects of microbial phytase supplementation (Natuphos 5000) at 2 dietary energy concentrations on their performance, and utilisation nitrogen (N), phosphorus (P), calcium (Ca) zinc (Zn) tibiae ash, Ca, P Zn concentrations. Four replicate pens (6 birds per pen) a completely randomised design were used in 2x2 factorial arrangement treatments contents metabolisable (11.72 12.55 MJ ME/kg) additions (0...
Avaliou-se a utilização do óleo essencial extraído dos frutos de aroeira-vermelha (Schinus terebinthifolius Raddi) na dieta frangos corte sobre o desempenho e morfometria intestinal. Utilizaram-se 240 pintos um dia idade, machos, da linhagem Cobb, distribuídos em delineamento inteiramente casualizado grupos cinco tratamentos quatro repetições: sem antibiótico anticoccidiano (controle negativo); com positivo); 0,1% aroeira; 0,2% 0,4% aroeira. O consumo ração, peso corporal conversão alimentar...
Objetivou-se avaliar os efeitos da inclusão de óleo essencial aroeira-vermelha (Schinus terebinthifolius Raddi) como promotor crescimento nas rações frangos corte sobre o desempenho e morfometria intestinal desses animais. Foram utilizados 300 pintos um dia vida, tipo corte, machos, linhagem Cobb. As aves foram alojadas em 20 boxes 2m² (15 boxe-1), distribuídos delineamento inteiramente casualizado, grupos quatro (4) tratamentos cinco (5) repetições, com 15 cada. Os identificados T1: dieta...
Abstract The aim of this study was to evaluate the inclusion different oil sources and dietary supplementation with vitamin E on composition fatty acids in rooster meat. Two hundred forty 30‐week‐old White Leghorn roosters were distributed a completely randomized factorial arrangement 5 × 2, using five (sunflower, soybean, canola, linseed fish) two levels antioxidant (30 400 mg kg −1 diet). intake fish canola diet reduced ( P < 0.05) content saturated unsaturated thigh Amongst thigh,...
The aim of this study was to evaluate the antibiotic susceptibility Listeria innocua (L. innocua) and monocytogenes monocytogenes) cells in presence citral carvacrol at sublethal concentrations an agar medium. terpenes L. culture medium provided a reduction minimal inhibitory concentration (MIC) all antibiotics tested. These effects were dependent on present combination potentiated activity by reducing MIC values bacitracin colistin from 32.0 128.0 μg ml⁻¹ 1.0 2.0 ml⁻¹, respectively. Thus,...
AbstractAbstractSix commercial probiotic products produced and marketed Italy (containing Lactobacillus GG, casei DG, reuteri, Bacillus clausii spores, Bifidobacterium longum Saccharomyces boulardii) were assayed for their stability during storage, acid, base bile tolerance adherence to human intestinal cells.Results indicate that even at conditions established by manufacturers, affects the microbial content of based on B. partially containing L. GG. Differences in acid found products, S....
The effect of dietary conjugated linoleic acid (CLA) in association with two vegetable oil sources on the fatty acids meat and giblets broiler chickens was evaluated. Two hundred 21-day-old were distributed a completely randomized factorial design 2 x 5 (two sources, soybean or canola oil; five levels CLA, 0.0, 2.5, 5.0, 7.5, 10.0g/kg). addition CLA to diet resulted an increase (P<0.05) deposition analyzed tissues. supplementation also reduced rate polyunsaturated saturated thigh, breast,...
Este trabalho objetivou avaliar o efeito da adição de níveis crescentes antibióticos associado ao farelo pimenta rosa (FPR) sobre a função hepática e desempenho frangos corte. Utilizou-se 528 pintos, machos, linhagem Cobb um dia idade distribuídos num delineamento inteiramente casualizado com seis tratamentos, quatro repetições 22 aves cada: T1: Controle Negativo (CN): Dieta Basal; T2: Positivo (CP): Basal 1,2% FPR; T3: CP+11ppm bacitracina Zn 17ppm salinomicina; T4: CP+22ppm 34ppm T5:...
The aim of this research was to evaluate the effect CLA association with two vegetable oil sources on body fat broiler chickens. Broilers were distributed in a completely randomized factorial design 2 x 5 (two sources, i.e. soybean or canola and five levels supplementation, 0.0, 2.5, 5.0, 7.5 10.0 g/kg). For both sexes, supplementation resulted heavier birds (P<0.05) when compared oil. final weight female significant explained by linear response (P<0.05). A reduction abdominal pad content...
The main goal of this work was to study the bacterial adaptive responses antibiotics induced by sublethal concentration citral on first-and second-generation cells Listeria monocytogenes serovar 4b (CECT 4032) and Salmonella enterica Typhimurium 443). first-generation were not pretreated with citral, while obtained from previously exposed during 5 h. trials conducted at 37°C. presence in culture medium antibiotic strips resulted a reduced minimum inhibitory (MIC) for Typhimurium. This result...
