Abstract:
Spray application offers low-cost and efficient
application of biologic and reduced concerns regarding diverse water
quality and medicator/proportioner function. The objective of the present
study was to evaluate the spray application of a
Lactobacillus-based probiotic on Salmonella enteritidis (SE)
colonization in broiler chickens. Day-of-hatch chicks were challenged with
Salmonella enteritidis (SE) by oral gavage alone, challenged with
SE and treated by coarse spray application of a commercially-availably
Lactic-acid bacterial probiotic (FM-B11™), or challenged with
SE and treated with B11 continuously in the Drinking Water (DW). Five days
post-challenge, cecal tonsils were collected for presence or absence of
SE. In Exp. 1, probiotic treatment by either spray or DW application
significantly (p<0.05) reduced SE recovery (55% and 50% respectively;
controls 85%) when chicks were held for 8h prior to challenge and
placement. Similarly, when probiotic spray treatment or water treatment
and challenge occurred simultaneously, with placement 8h after treatment,
a marked and significant reduction of SE recovery was noted after 5d (10%
and 40% respectively, controls 55%). In Exp. 2, when probiotic spray
treatment and challenge occurred simultaneously, with placement 8h after
treatment, a significant reduction of SE recovery was again noted in both
the spray and DW application (80% controls, 15% spray, 15% DW). Taken
together, these results suggest that spray application of B11, when
performed in the manner described above, can be effective for protection
of chicks against Salmonella infection.
