An experiment was conducted on 400 broilers to evaluate the effects of dietary supplementation ofantibiotic and probiotic on performance of birds under heat stress condition. The first group of chickens, thecontrol group, received a diet without any antibiotic and probiotic. The second group received diet with0.02% virginiamycin antibiotic; the two other groups were fed diets with 0.05% and 0.1...

probiotics are live microorganisms with beneficial health effects on host animals which exert their effects on performance, gastrointestinal tract and immune system. various probiotic products are available in the market. this study compared the effects of various probiotic products on broiler performance, intestinal morphology and some immunological and hematological parameters. five probiotic...

the effects of various routes of probiotic administration on performance, small intestine morphology and serum cholesterol of broiler chickens, were studied. we assigned 225 day old chicks (ross 308) to five experimental groups including control and four hatchery administration methods comprised of in ovo injection, oral gavage, spray application and cloacal inoculation. all of these were chall...

We have previously described the safety and immunomodulatory effects of Lactobacillus paracasei CNCM I-4034, Bifidobacterium breve CNCM I-4035 and Lactobacillus rhamnosus CNCM I-4036 in healthy volunteers. The scope of this work was to evaluate the effects of these probiotic strains on the hepatic steatosis of obese rats. We used the Zucker rat as a genetic model of obesity. Zucker-Lepr(fa/fa) ...

Campylobacteriosis is the most frequent zoonotic disease in humans worldwide, and the contaminated poultry meat by Campylobacter jejuni can be considered one of the important sources of enteric infections in humans. The use of probiotics, which can help to improve the natural defense of animals against pathogenic bacteria, is an alternative and effective approach to antibiotic administration fo...

This study was carried out to evaluate the effect of probiotic (Bacillus latrospores and Bacillus licheniformis) on growth and survival of Silver carp larvae (Hypophthalmichthys molitrix). Rotifers (Brachionus plicatilis) were used as live prey vehicle for probiotic transport. They were cultured in sea water with 15 ppt salinity and Nannochloropsis oculata microalgae was used as feed. Five trea...
