Abstract:
... Tilapia is one of the most extensively farmed fish on a global scale. Lately, many studies have been carried out to select and produce probiotics for cultured fish. Bacteria from the genera Bacillus, Lactiplantibacillus (synonym: Lactobacillus), and Lactococcus are the most widely studied with respect to their probiotic potential. Among these microorganisms, Lactococcus lactis has outstanding pros ...

... This study evaluated the production of two black soldier fly larval meals (BSFLMs) when rearing the larvae on brewers’ spent grains (BSFLM-B) or a commercially available substrate (BSFLM-C, Gainesville house fly diet). The resulting nutrient composition of the BSFLMs were significantly impacted by the feeding substrates, and they were evaluated as a protein ingredient for red drum, where BSFLM-B a ...

... Plant extracts have been used over time in traditional medicine, mainly for their antimicrobial activity as well as for their medicinal effects. Plant-derived products contain secondary metabolites that prevent pathogenic microbial growth similar to conventional medicines. These secondary metabolites can enhance animal health and production in a more natural or organic manner and may contribute to ...
... The objective of this study was to investigate possible effects of sodium butyrate and sodium propionate individually, and in combination, against common pathogenic bacteria and intestinal microbiota in vitro, and when supplemented in high-plant-protein diets for the carnivorous red drum. These organic acids (OA) presented synergistic effects when inhibiting Aeromonas hydrophila and Streptococcus ...

... The addition prebiotics in broiler diets can benefit digestion and nutrient abortion. The objective of the present study was to evaluate the effects of moringa leaf powder and agave inulin on growth performance, intestinal morphology, and slaughter traits of broiler chickens over 40 d of grow-out. A total of 280 broilers (Ross 308) aged 1 d were randomly allocated to 4 treatments, with 7 replicate ...
... The objective of this study was to evaluate if immunostimulation by the β-1,3-glucan paramylon (PML) could be further enhanced with vitamin C (vit. C) for hybrid striped bass (HSB). Two separate trials were conducted in vitro and in vivo, using a 2 × 2 factorial design, where the main effects tested were PML and vit. C, or their combination (PML + vit. C), to measure possible synergistic effects o ...

... Spoiled silages can harbor pathogenic and antimicrobial-resistant microbes. The potential of some antimicrobial additives to inhibit certain pathogenic and antimicrobial-resistant bacteria in air-exposed silage was measured using pure and mixed bacterial cultures. With pure cultures, laurate and monolaurin (5 mg·mL⁻¹) caused decreases (P < 0.05) of 4 to >7 log₁₀ colony-forming units (CFU)·mL⁻¹ in ...

... Strategies are sought to reduce the carriage and dissemination of zoonotic pathogens and antimicrobial-resistant microbes within food-producing animals and their production environment. Thymol (an essential oil) is a potent bactericide in vitro but in vivo efficacy has been inconsistent, largely due to its lipophilicity and absorption, which limits its passage and subsequent availability in the di ...

... Staphylococcus aureus (S. aureus) causes gastrointestinal illness worldwide. Disinfectants are used throughout the food chain for pathogenic bacteria control. We investigated S. aureus bioavailability in swine Mandibular lymph node tissue (MLT) and pork sausage meat (PSM), established susceptibility values for S. aureus to disinfectants, and determined the multilocus sequence type of MRSA strains. ...

... Current diets of broiler chickens tend to increase protein levels to support the high productive parameters that are obtained after genetic, management, and sanitary improvements, among others. However, an increase in dietary protein levels does not always accompany an increase in broiler productive efficiency due to multiple factors involved in the production system. The objective of this study w ...

... Poultry litter is a potentially valuable crude protein feedstuff for ruminants but must be treated to kill pathogens before being fed. Composting kills pathogens but risks losses of nitrogen due to volatilization or leaching as ammonia. Treatment of poultry litter with ethyl nitroacetate, 3-nitro-1-propionate, ethyl 2-nitropropionate (at 27 µmol/g), decreased numbers of experimentally-inoculated S ...

... An electrochemical prototype (ECP) was developed and evaluated to determine NaCl electrical variables [volt (V), ampere (A), resistance (R) and power (P)] and its use in fresh cheeses. The ECP circuit consisted of two electrodes, an aluminum (anode) and a copper (cathode). The experimental parameters established in the ECP were distance between electrodes and the presence of a resistor. Seven trea ...

... The aim of this study was to compare two Mexican chorizo formulations (treatments) considering physicochemical, microbiological and sensorial attributes over 14 days in refrigeration. One formulation involved vinegar (T1= control chorizo + 2.4 % vinegar) and the other oregano essential oil (OEO; Lippia berlandieri Schauer) (T2= chorizo + 2.4 % OEO) as a substitute for vinegar. Both formulations we ...

We assessed the effects of a fishmeal (FM)‐ and two soya‐based diets [without or with prebiotic (GroBiotic® ‐A; GBA) supplementation] on the production performance, non‐specific immunity, blood parameters and gut microbiota diversity of red drum, Sciaenops ocellatus. All diets were formulated to contain 450 g/kg crude protein (CP) and 120 g/kg lipid. A combination of soya bean meal and soya protei ...

... Susceptibility profiles were determined for 111 Campylobacter coli strains obtained in 1998 to 1999 and 2015 from market age pigs and pork chops against 22 disinfectants and 9 antimicrobials. Resistance to tetracycline (TET) was observed in 44.4% of 1998 to 1999 strains, and the antibiotic resistance profile was TET. But strains obtained in 2015 from swine and retail pork chops had 75% TET resista ...
