It has been shown that prebiotics encourages the growth of endogenous microbial population groups such as Bifidobacteria and Lactobacilli which are particularly stimulated, and these bacteria species are considered as beneficial to animal health [ 4 ].
Diversity is a combination of richness and evenness. Lactic acid bacteria increase the acidity of the intestine, which inhibits the multiplication of harmful bacteria Rahimi et al. Marriott I Osteoblast responses to bacterial pathogens: Ash and calcium contents of tibia at 21 and 42 days of age were determined.
In cecal microbiota, the majority of Clostridiales detected fall primarily into Ruminococcaceae, Lachnospiraceae and Clostridiaceae families Figure 5 B. According to previous investigations intestinal microbiota affected mucin turnover by stimulation of mucin gene expression Smirnov et al.
Also, the interesting transport of immune cells of PRO in liver was reported by other study 34 where probiotic bacteria reduced monocyte and macrophage recruitment to the intestines and spleen compared to control animals. With increases in age, the negative effects of challenging and beneficial effects of probiotic on bone mineralization diminished; since at 42 days of age, challenging or probiotic treatment had no effect on ash and calcium contents of tibia.
In broiler nutrition, probiotic species belonging to Lactobacillus, Streptococcus, Bacillus, Bifidobacterium, Enterococcus, Aspergillus, Candida, and Saccharomyces have a beneficial effect on broiler performance [ 10 ], modulation of intestinal microflora and pathogen inhibition [ 11 ], and promoting microbiological meat quality of broilers [ 12 ].
J Appl Poult Res Prebiotic and probiotic groups showed lower body weight than synbiotic and control groups. Comp Immunol Microbiol Infect Dis Find articles by Nihar Ranjan Sarangi L. PRO can promote important histologic alterations related to activation of defense response and gut absorption.

Rahimi S, Khaksefidi A A comparison between the effects of a probiotic Bioplus 2B and an antibiotic virginiamycin on the performance of broiler chickens under heat stress condition. Am J Physiol Vet Rec No differences in ISI scores in liver were found among treatments in non-challenged birds at 7 days.
Antibiotics have long been used as growth promoters. As expected, the data on microbiota presented high coefficients of variation addressing the difficulties in establishing statistical differences.
Dissemination and tracking of Salmonella spp. Mortality in each experimental unit was recorded daily throughout the experiment. Swaggerty CL, Kaiser P, Rothwell L et al Heterophil cytokine mRNA profiles from genetically distinct lines of chickens with differential heterophil-mediated innate immune responses.
Therefore, this layer is the first line of the host intestinal defense and influences nutrient digestion and absorption. A way of potentiating the efficacy of probiotic preparations may be the combination of both prebiotics and probiotics as synbiotics that beneficially affects the host by improving the survival and implantation of live microbial dietary supplements in the gastrointestinal tract.

Liver histologic alterations by ISI and immunohistochemistry analysis are summarized in Tables 3 and 4respectively.
Previous studies have shown the influence of probiotic microorganisms on intestinal morphology Chichlowski et al.Broiler chicks that were fed mono-strain probiotic which included Bacillus subtilus had a higher mucin gene expression and also a better feed conversion rate compared to the control group, but, no significant differences were found in relative MUC2 gene expression between birds fed with BS and LAB probiotic supplemented vsfmorocco.com by: The objective of this trial was to evaluate the ability of a probiotic composed of three different B.

Effect of Bacillus subtilis spore (GalliPro Abstract The experiment was conducted to evaluate the nutrients equivalency value of Bacillus subtilis spore (GalliPro®) for broiler chickens and its potential for decreasing feed nutrients concentration and cost. A total of day old Ross broiler chicks was allocated in 6 treatments (2 sexes×3 diets) with 6 replica-tion for 7 weeks.
The probiotic (Bacillus subtilis – strain DSM ) improved feed conversion when added to broiler diets containing no antibiotic growth promoters. Despite being banned in some markets, antibiotic inclusion in broiler diet improves feed conversion ratio.
Two hundred and twenty five one day-old Ross () broiler chickens were randomly divided into five experimental groups, Five groups were fed with a basal diet (control) or diets supplemented with. Sadeghi AA, Shawrang P, Shakorzadeh S () Immune response of salmonella challenged broiler chickens fed diets containing Gallipro®, a Bacillus subtilis probiotic.
