Zusammenfassung
[EN] Sodium butyrate is a sodium salt of a
volatile short-chain fatty acid (butyric acid) used to
prevent Salmonella Enteritidis infection in birds. Three
groups of fifty 1-d-old broilers each were fed the following
diets: T0 = standard broiler diet (control); T1
= standard broiler diet supplemented with 0.92 g/kg
of an additive with free sodium butyrate (Gustor XXI
B92); and T2 = standard broiler diet supplemented
with 0.92 g/kg of an additive with sodium butyrate
partially protected with vegetable fats (Gustor XXI
BP70). Twenty percent of the birds were orally infected
with Salmonella Enteritidis at d 5 posthatching and fecal
Salmonella shedding was assessed at d 6, 9, 13, 20,
27, 34, and 41 of the trial. At d 42, all birds were slaughtered
and 20 of them dissected: crop, cecum, liver, and
spleen were sampled for bacteriological analyses. Both
butyrate-based additives showed a significant reduction
(P < 0.05) of Salmonella Enteritidis infection in birds
from d 27 onward. However, the partially protected butyrate
additive was more effective at the late phase of
infection. Partially protected butyrate treatment successfully
decreased infection not only in the crop and
cecum but also in the liver. There were no differences in
the spleen. These results suggest that sodium butyrate
partially protected with vegetable fats offers a unique
balance of free and protected active substances effective
all along the gastrointestinal tract because it is slowly
released during digestion.
