2. Probiotics in poultry nutrition: cost or opportunity?
BAROMFI CONGRESS 2013
MANY TIMES PROBIOTICS FAIL TO GIVE A RELIABLE
RESPONSE IN THE BIRDS – WHY?
USE OF SINGLE-STRAIN PROBIOTICS
COLONIZATION OF JUST
A PART OF THE GIT
USE OF NOT SPECIE-SPECIFIC STRAINS
• SLOWER REPLICATION
• QUICK ELIMINATION (ONCE
REGULAR CONSUMPTION OF THE
PROBIOTIC HAS CEASED) – Tannock, 2001
WRONG POSITIONING GROWTH PROMOTION??
3. SO… IN ORDER TO OBTAIN A RELIABLE REPLY FROM
THE HOST A PROBIOTIC SHOULD BE
MULTI-
STRAIN
• COLONIZATION OF THE
WHOLE GIT TRACT
SPECIE-
SPECIFIC
(selected by the
gut of the bird)
• FASTER MULTIPLICATION
• LOW ELIMINATION
WELL
POSITIONED
• IMMUNOMODULATION
• COMPETITIVE EXCLUSION
LESS PATHOGEN PASSAGE
INTO THE BLOOD STREAM

9. Different steps…
Probiotics – selection criteria
ISOLATION OF
BACTERIAL STRAINS
• Isolation out of the chicken gut
• Diff. selective and non-selective media
• Diff. conditions (aerobic, fac. anaerobic,
anaerobic)
CHARACTERISATION OF
BACTERIAL STRAINS
• Physiologica and biochemical
• Cultural-morphological
• Molecular biological
EVALUATION OF
STRAINS
• Pathogen inhibition
• Adhesion to intestinal cell wall
• Met. end products, stability, safety
status
10. • From poultry to poultry
• Chosen from different parts of the GIT.

Bifidobacterium animalis Ileum

Probiotics – different strains growing in different GIT tracts
12. B.C.O. (Bacteria Chondronecrosis Osteomyelitis) LAMENESS
Worldwide surveys indicate the wide spread of lameness.
Studies in Europe show high level of lameness in broilers with 14-30% of
the birds with lameness score >3 (Sanotra et al., 2003).
High prevalence rates up to 27.6% (UK- Knowles et al., 2008)
80% of the cases were attributed to BCO (Bacterial Chondronecrosis and
Osteomyelitis) - 5% mortality.
10-15% of normal broilers suffer from subclinical BCO and the condition
started to appear in younger birds (Thorp et al., 1993).

24. Trial design
• Gumboro vaccination on day 16
• Oral challenge (3 times a day) of infected groups with C. perfringens 56 (type A
strain which carries netB; no beta-2 or enterotoxin genes) at days 17, 18, 19 and
20
• Oral gavage with a ten-fold dose of vaccinal Eimeria oocysts (Paracox-5) at day
18
• At days 22, 23, and 24, ten birds from each group were euthanized and intestinal
lesions in the small intestine (duodenum to ileum) were scored
Development of N.E. - Ghent University (Belgium)
25. Intestinal lesion scoring
0: no gross lesions
1: congested intestinal mucosa
2: small focal necrosis or ulceration (1 - 5 foci)
3: focal necrosis or ulceration (5 - 16 foci)
4: focal necrosis or ulceration (16 or more foci)
5: patches of necrosis 2 - 3 cm long
6: diffuse necrosis typical of field cases
Lesion scores of 2 or more were classified as necrotic enteritis positive.
The statistical analysis was carried out for the 3 sampling days (total) by the means of
multivariable logistic regression.

TAKE-HOME MESSAGES
• Probiotics can enhance immunity
• Probiotics can create a non immune defensive barrier in the
GIT
• Multi-specie probiotics are more efficient than single-strain
ones (they can colonize the whole GIT)
• Specie-specific probiotics can colonize better the GIT and
stay longer in the GIT after stopping the administration
• Multi-specie, specie-specific probiotics can give a benefit in
terms of BCO lameness reduction
Acute-phase inflammation modulation,
N.E. reduction
