Conventional guinea pigs provided with a solution of 5% (wt/vol) degraded carrageenan as the sole source of oral fluids developed ulcerations of their ceca and large intestines within 30 days. Similar lesions were not detected in germfree guinea pigs treated in an identical manner, suggesting that an intestinal microflora was necessary for development of intestinal lesions. To simplify the bact...

This study was conducted to investigate the effects of Clostridium butyricumon growth performance, immune function, and cecal microflora in broiler chickens challenged with Escherichia coli K88. Three hundred sixty 1-d-old broiler chickens were randomly divided into 4 treatments: negative control (NC) birds were fed a basal diet and not challenged with E. coli K88; positive control (PC) birds w...

the aim of the present study was to evaluate the effect of purslane on immune responses and cecal microflora composition of broiler chickens. one hundred forty four day old broiler chicks (ross 308) were allocated randomly in 3 groups and 4 replicates to receive diets supplemented with 0 (control), 1 and 2 % of dried purslane. at 21 and 35 days of age 1 ml of sheep red blood cell (srbc) injecte...

Adding organic acids to piglet diets is known to be helpful in overcoming postweaning syndrome, and butyric acid is known to be the main energy source for the epithelial cells of the large intestine and the terminal ileum. This study investigated the effect of sodium butyrate (SB) on in vitro and in vivo swine microflora, piglet growth performance, and intestinal wall morphology. During a 24-h ...

Four hundred and fifty 1-d-old male Lingnan Yellow broiler chickens were used to investigate the effects of Clostridium butyricum on growth performance, immune function, and cecal microflora. The birds were randomly assigned to 5 treatments and offered the same antibiotic-free basal diets for 42 d. The treatments were as follows: no addition (control), 1 × 10(7) cfu C. butyricum/kg of diet (CB1...

This experiment was conducted to examine the effect of dietary supplement with green Brazilian propolis on body weight (BW), weight gain (BWG) and cecal microflora in broiler chickens raised under heat stress condition. A total of 504 15-d-old male broiler chickens (Ross 708) were randomly allocated to 6 treatments, each with 4 replicate pens per treatment, 21 chickens per pen from hatch to 42 ...

The effects of rice starch-isoflavone diet or potato starch-isoflavone diet on plasma concentration of isoflavones, plasma lipids, cecal enzyme activity, and intestinal microflora were studied. Male 15-wk-old mice were fed a rice-starch-based or potato-starch-based diet supplemented with isoflavones for 4 wk, and plasma samples, cecal contents, and feces were collected individually. Plasma equo...

Campylobacter is a leading cause of foodborne illness in the United States, and epidemiological evidence indicates poultry products to be a significant source of human Campylobacter infections. Caprylic acid, an eight-carbon medium-chain fatty acid, reduces Campylobacter colonization in chickens. How caprylic acid reduces Campylobacter carriage may be related to changes in intestinal microflora...

Ceftobiprole and ceftobiprole medocaril did not promote growth of or toxin production by Clostridium difficile in mouse cecal contents, whereas ceftazidime, cefoxitin, ceftriaxone, cefotaxime, and ertapenem did. The relatively low propensity of ceftobiprole to promote C. difficile was attributable to inhibitory activity against C. difficile and sparing of anaerobic microflora.

DENEV, S. A., 2006. Effect of different growth promoters on the cecal microflora and performance of broiler chickens. Bulg. J. Agric. Sci., 12: 461-474 The objective of this study was an evaluation of the effects of different growth promoters: probiotic Lacto-Sacc® (Alltech, Inc. USA), nutritive premix Pharmastim and nutritive antibiotic Avilamycin on the cecal microflora and performance of bro...
