The document introduces probiotic microbiota from the gastrointestinal tract of commercial poultry, emphasizing the definition and characteristics of probiotics, particularly beneficial strains like Lactobacillus and Bifidobacterium. It discusses the role of probiotics in enhancing chicken health and performance, including various metabolic functions of the gut microbiota. Additionally, it highlights the economic importance of probiotics as feed supplements in the poultry industry.
Probiotic from chicken's GIT
- 1. Basic Introduction of Probiotic microbiota from Gastrointestinal tract of Commercial Poultry. Presentation on Submitted by Galib Ahsan Department of Biotechnology & Genetic Engineering Islamic University, kushtia-7003, Bangladesh
- 2. Probiotics Probiotics are defined as “live microorganisms which when administered in adequate amounts confer a health benefit on the host. Characteristics of probiotic bacteria Non-toxic and non-pathogenic. Resistance to gastric juice and bile Persistence in the GI. Adhesion to epithelium or mucus. Production of antimicrobial substances. Antagonism towards pathogenic bacteria. Modulation of immune responses.
- 3. Most used probiotic genera Lactobacillus Bifidobacterium Streptococcus (S. thermophilus) Lactic acid bacteria, especially Lactobacillus, are the most commonly used microorganisms as probiotics because of the perception that they are desirable members of the intestinal microflora and because these bacteria have “Generally Recognized As Safe” (GRAS) status. In practice, lactobacilli and bifidobacteria (and probiotics based on these organisms) are extremely rare causes of infections in humans. FAO/WHO guidelines recommended that the antibiotic resistance or susceptibility pattern of every probiotic strain (including bacteria with GRAS status) be determined.
- 4. Role of chicken Gastrointestinal probiotic microbiota Short chain fatty acids (acetic acid, butyric acid and propionic acid) Antimicrobial compounds (e.g., bacteriocins),lower triglyceride Organic acids (e.g., lactic acid) vitamins (e.g., vitamin K and vitamin B groups)
- 5. The Chicken Digestive System Gut Microbiota in the Gastrointestinal tract of Chicken includes the crop, proventriculus, gizzard, duodenum, jejunum, ileum, caeca, large intestine, and cloaca. Each GI tract section has different metabolic functions that shape the microbial community.
- 6. Probiotics in poultry industry as feed supplements Probiotics are being considered to fill the gap of antibiotics in poultry Weight gain significantly higher in probiotic fed birds Enhance the meat quality Economic importance of probiotics in poultry Economic importance of probiotics in poultry
- 7. Lactobacillus spp. as probiotics Lactobacillus was the earliest discovered among other probiotics. Lactobacillus is the dominant bacteria in animal and human gastrointestinal system. To isolate and identify lactic acid bacteria from GIT which can be a good source of probiotics. Huge significant research have been done on probiotic bacteria in last 10 years. The Lactobacillus species are the most predominant lactic acid bacteria associated with probiotics as feed supplements for animals. Many evaluation would confirm that Lactobacillus spp. as a probiotic have potential health benefit specially clinical gastroenterology.
