Although it is recognised that high levels of dietary insoluble nonstarch polysaccharides (NSP) depress growth in pigs (1), trials investigating the effect of dietary soluble NSPs (sNSP) on performance have produced inconsistent results, depending on the type of grain fed, age of pig and other interacting factors. Diets with high levels of sNSP depress growth and have anti-nutritive properties ...

Background: Although Escherichia coli (E. coli)is a part of intestinal normal microflora of warm-blooded animals, includingpoultry, outbreaks occur in poultry raised below standard sanitation and duringthe course of respiratory or immunosuppressive diseases. Avian pathogenic E.coli (APEC) harbors several genes associated with virulence andpathogenicity. APEC strains are responsible for some dis...

understanding the distributions of poultry diseases will help planning for disease control and prevention more effectively. studies on poultry diseases in iran are scarce. we investigated the incidence of mortality in broiler chicken flocks in iran as part of a national project. specifically, documents from september 2004 to november 2005 related to the mortality of broilers that were covered b...

Avian Pathogenic Escherichia coli (APEC) is a major pathogen within the poultry industry. However disease, especially in broiler chickens, may be caused by range of E. coli genotypes that carry few, if any, virulence factors associated with APEC. Furthermore, commensal E. coli in the intestines of healthy birds may carry an array of APEC virulence factors suggesting they have potential to cause...

Vaccination in poultry production is vital to protect the birds against the main viral diseases: Marek’s disease, infectious bursal disease or Gumboro disease, infectious bronchitis, Newcastle disease, avian influenza, etc, as well as bacterial diseases: colibacillosis, mycoplasma infections, etc and also coccidiosis. If we refer more specifically to broiler chicken meat production worldwide, t...

A chemical characteristic of the feces of diarrheal piglets permits differentiation among piglets receiving antibiotic treatment and those with colibacillosis or dyspepsia. A high concentration of lactic or succinic acid was observed in the diarrheic feces of piglets receiving antibiotic treatments and those with dyspepsia; however, no lactic or succinic acids were detected in piglets with coli...
