@AgNPs and @AgNPs: a comparative analysis for antibacterial application.

Although medicinal herbs contain many biologically active ingredients that can act as antibiotic agents, most of them are difficult to dissolve in lipids and absorb through biofilms in the gastrointestinal tract. Besides, silver nanoparticles (AgNPs) have been widely used as a potential antibacterial agent, however, to achieve a bactericidal effect, high concentrations are required. In this work, AgNPs were combined into plant-based antibiotic nanoemulsions using biocompatible alginate/carboxyl methylcellulose scaffolds.

Effects of dietary fiber sources on bacterial diversity in separate segments of the gastrointestinal tract of native and exotic pig breeds raised in Vietnam.

Background And Aim: Dietary fiber has distinctive effects on the environment and microbiota of the pig's intestinal tract. This study was conducted at the naturally ventilated facility of the experimental station, National Institute of Animal Sciences, Vietnam, to examine the effects of fiber sources in diets on the intestinal microbiota of two different pig breeds raised in Vietnam.

Materials And Methods: A total of 18 native and 18 exotic pigs with average initial body weights of 9.

Growth performance, carcass quality characteristics and colonic microbiota profiles in finishing pigs fed diets with different inclusion levels of rice distillers' by-product.

The aim of this study was to evaluate the effects of diets containing rice distillers' by-product (RDP) on growth performance, carcass characteristics, meat quality, and gut microbiota of fattening pigs. Twenty-four crossbred finishing pigs (Duroc × Landrace × Yorkshire), 56.9 ± 3.

In growing pigs, nutritive value and nutrient digestibility of distillers' by-products obtained from two varieties of rice.

In South-East Asia, rice distillers' by-product (RDP) is a widely abundant feedstuff whose adequate incorporation into pig diets is still questionable. Especially, effects of RDP on nutrient digestibility of growing pigs fed corn-soybean meal-based diet are lacking. The objective of this study was to determine nutrient digestibility and energy value of ordinary (ORDP) and glutinous (GRDP) rice distillers' by-product in growing pigs.

Validation of a two-plate microbiological method for screening antibiotic residues in shrimp tissue.

Microbiological inhibition screening tests could play an important role to detect residues of antibiotics in the different animal food products, but very few are available for the aquaculture products in general, and for shrimps in particular. A two-plate microbiological method to screen shrimp for residues of the most commonly used antibiotics has been developed and validated according to criteria derived from the European Commission Decision 2002/657/CE. Bacillus subtilis was used as a sensitive strain to target antibiotics.
