Effects of antimicrobial feed additives on gut microbiology and blood parameters of weaned piglets

چکیده
As a result of antibiotic resistance in human pathogenic bacteria, alternatives for Antibiotic Growth Promoters (AGP) have been developed in recent years. Herbs and botanicals can be seen as such an alternative (WENK, 2003). Essential oils derived from different plants have been tested over the years to identify their effects on animal performance. Essential oil extracts from Oregano, with its chemical main component carvacrol, has been used as feed additive and was investigated in numerous feeding trials where it showed a positive influence on piglets performance (e.g. WALD et

Optimizing Production of Two Potential Probiotic Lactobacilli Strains Isolated from Piglet Feces as Feed Additives for Weaned Piglets
Two probiotic strains, Lactobacillus johnsonii x-1d-2 and Lactobacillus mucosae x-4w-1, originally isolated from piglet feces, have been demonstrated to possess antimicrobial activities, antibiotic resistances and interleukin-6 induction ability in RAW 267.4 macrophages in our previous study. These characteristics make L. johnsonii x-1d-2 and L. mucosae x-4w-1 good candidates for application in...
متن کاملChenodeoxycholic acid reduces intestinal permeability in newly weaned piglets.
Piglets are highly susceptible to gut health-related problems. Intravenously administered chenodeoxycholic acid (CDCA) affects gut health mediated through glucagon-like peptide 2 (GLP-2). To test whether CDCA is a suitable feed additive for improving gut health, a trial was performed with newly weaned (21 d) piglets offered a diet with or without 60 mg CDCA/kg feed (n = 24/treatment). Upon wean...
متن کاملUse of recombinant porcine β-defensin 2 as a medicated feed additive for weaned piglets
Post-weaning diarrhoea (PWD) in piglets is associated with colonization of the intestine with bacterial pathogens. In this study, we evaluated the use of recombinant porcine β-defensin 2 (rpBD2) as a medicated feed additive for weaned piglets. The crude extract from the culture supernatant of rpBD2-expressing Pichia pastoris was used as a medicated feed additive for weaned piglets. Dietary trea...
متن کاملStudies on the effects of essential-oil-based feed additives on performance, ileal nutrient digestibility, and selected bacterial groups in the gastrointestinal tract of piglets.
The aim of this study was to assess the effects of 2 different phytogenic products on performance, ileal nutrient digestibility, and composition of the intestinal microbiota. The 2 phytogenic products contained different essential oil mixtures (EOM) characterized by either menthol (Mentha arvensis; EOM-M) or cinnamon aldehyde (Cinnamomum aromaticum; EOM-C) as main constituents. Three treatments...
متن کاملThe effect of a mixture of dairy-based feed ingredients, vegetable fats, and yeast cell walls on performance and innate immunity of weaned piglets.
Positive effects of yeast concentrate on immunity and performance of weaned piglets have been reported. However, the effects on innate immunity were not examined. Natural antibodies (NAb) are part of innate immunity and have been related to health and survival in fish, poultry, rodents, and man. Yeast cell walls may also affect innate immunity of weaned piglets. We studied the effect of Nuklosp...
