Responses to anaesthesia with essential oil (EO) of Aloysia triphylla (135 and 180 mg L−1) tricaine methanesulfonate (MS222) (150 300 were assessed in silver catfish. Exposure the anaesthetics elicited a stress response species. In case MS222, it was displayed as release cortisol into bloodstream, elevation hematocrit plasma ion loss. The EO presented cortisol-blocking properties, but increased haematocrit disturbances hydromineral balance observed. Liver antioxidant/oxidant status...
Para se avaliar as adaptações morfofuncionais do trato digestório de cordeiros alimentados com silagem bagaço azeitona, foram utilizados 35 machos, não castrados, oriundos cruzamento entre raças Texel e Ile France, idade média 55 dias. Os animais submetidos a cinco planos nutricionais (ad libitum), constituídos por diferentes níveis substituição milho sendo abatidos aproximadamente 36kg peso vivo, em um delineamento inteiramente casualizado. Após o abate, rúmen, retículo, omaso, fígado,...
In this study, the influence of temperature variation on blood and oxidative stress parameters pacu Piaractus mesopotamicus juveniles was evaluated. Fish were subjected to gradual changes temperature, over 5 days, by 24°C until reaching experimental temperatures 18, 21, 24 (control), 27 30°C. There significant differences (p < .05) in glucose lactate both haematological relationships parameters. Glucose levels increased at 30°C decreased 21°C. Lactate highest 18°C. While haematocrit higher...
Mugil liza juveniles (6.69 ± 0.06 g) were subjected to dietary citral (0-control, 0.5, 1.0 and 2.0 mL per kg feed) for 45 days, its possible effects on zootechnical metabolic parameters, digestive enzymes, innate immunity, oxidative status liver damage evaluated. At the end of experiment, fish fed feed showed a greater weight gain protein retention efficiency, as well enhanced activities pepsin (stomach) amylase (intestine) compared with control fish. Citral supplementation decreased...
Quillaja saponaria and Yucca schidigera are plants rich in saponins, which present surfactant or detergent properties with molecules containing fat-soluble nucleus either a steroid triterpenoid structure. yucca biomass also contain polyphenols, possess antioxidant, antimicrobial, anti-inflammatory properties. Plant-based feed additives have been increasingly used poultry feeds; therefore, this study was conducted to evaluate the effects of an additive polyphenols saponins proprietary blend...
Morphometry of gills and antioxidant/oxidant status in gills, brain, liver blood Rhamdia quelen sedated with propofol were studied. The purpose was to investigate structural functional responses upon administration the drug order validate its use for species. fish exposed 0, 0.4 or 0.8 mg L−1 1, 6 12 h, which are times normally used live transport. Propofol induced an increase chloride cell non-respiratory epithelium gill. Standard biochemical assays (thiobarbituric acid reactive substances...
This study evaluates whether humic acid (HA; Aldrich) protects the silver catfish, Rhamdia quelen (Quoy & Gaimard, 1824), against exposure to acidic pH. Survival, levels of Na+, Cl- and K+ plasma, hematocrit, hemoglobin erythrocyte morphometry were measured. Fish exposed 0, 10, 25 50 mg L 1 HA at four pH levels: 3.8, 4.0, 4.2 7.0 up 96 hours. None fish 3.8 survived for hours into experiment, survival subjected 4.0 decreased when concentration increased. Plasma Na+ was acidic, with no...
R-(+)-limonene is a monoterpene from plants of the genus Citrus with diverse biological properties. This research evaluated effects dietary supplementation on growth, metabolic parameters in plasma and liver, antioxidant stress responses silver catfish, Rhamdia quelen, challenged or not Aeromonas hydrophila. Fish were fed for 67 days different doses diet (control 0.0, L0.5, L1.0, L2.0 mL/kg diet). On 60th day, challenge A. hydrophila was performed. potentiated productive performance fish....
This study evaluated the effects of dietary supplementation with citral on growth performance and intestinal parameters, specific activity digestive enzymes Sardinella brasiliensis. 240 juvenile S. brasiliensis were randomly distributed in a recirculating aquaculture system (RAS) composed 12 circular tanks 150 L (n = 20 per tank). A diet without addition (control) three diets containing different levels inclusion (0.5, 1.0 2.0 mL kg*feed–1) used fish feeding management during days. The...
ABSTRACT: Humic substances are organic compounds that possess high molecular weight and formed by the decomposition of plant materials. comprise humic acids, fulvic acids humin. (HA) have shown to be able provide some protection biological membranes fish in water with low pH, replacing protective action Ca2+. Thus, this studyaimed observe growth silver catfish ( Rhamdia quelen ) juveniles exposed pHs 5.5 6.5 different levels HA: 0, 10, 25 50mg L-1. Results showed that, irrespective HA was...
The aim of this study was to determine whether purinergic signaling is a pathway associated with fumonisin B1 (FB1)-induced impairment immune and hemostatic responses. We also determined dietary supplementation diphenyl diselenide (Ph2Se2) prevents or reduces these effects. Splenic nucleoside triphosphate diphosphohydrolase (NTPDase) activity for adenosine (ATP) diphosphate (ADP) as substrates total blood thrombocytes counts were significant lower in silver catfish fed FB1-contaminated diets...
The present study evaluated different levels of the essential oil Nectandra grandiflora (EONG) in diet juvenile Colossoma macropomum. juveniles (0.75 ± 0.05 g) were fed four experimental diets with differing EONG (0, 0.5, 0.75, and 1.50 mL/kg). After 20 days, weight, daily weight gain, specific growth rate, feed consumption per fish highest for 0.5 mL EONG/kg, while after 30 only that remained highest. viscerosomatic index was EONG/kg hepatosomatic higher groups received dietary days. 1.5...
O objetivo deste estudo foi avaliar o efeito do composto corporal sobre a produção de leite vacas da raça Holandesa primeira, segunda e terceira lactação. Para avaliação, foram usadas 133 vacas, selecionadas um rebanho 280 animais em lactação, classificadas como pequenas, médias grandes, com base no (estatura x 10 + força 5 profundidade 3 largura garupa 2)/20.

The trend toward using plant-based ingredients in aquafeeds has raised important concerns for aquaculture owing to the negative impacts of mycotoxins on fish health; with emphasis contamination by fumonisin B1 (FB1). brain is an target FB1; however, study pathways linked damage limited analysis histopathological alterations. Reports have demonstrated protective effects dietary supplementation diphenyl diselenide (Ph2Se2) brains subjected several environmental insults; nevertheless, its...
This study investigated the effects of ultrasound therapy on haematological dynamics and plasma fibrinogen during inflammatory phase muscle injury.
