| Summary: | The objective of this study was to evaluate in vitro
antimicrobial and anti-biofilm activity of sodium long chain polyphosphate
(SLCPP) and effect of dietary supplementation of SLCPP on growth performance,
organ characteristics, blood metabolites, and intestinal microflora of broilers.
Antimicrobial activities of SLCPP were observed against Escherichia
coli O157:H7, Listeria monocytogenes,
Salmonella enterica ser. Pullorum, Shigella
sonnei, Klebsiella pneumonia, Pseudomonas
aeruginosa in agar well diffusion assay. In addition, SLCPP
demonstrated good anti-biofilm activity against K. pneumonia
and P. aeruginosa. Furthermore, to investigate the dietary
effect of SLCPP, a total of 480 1-day-old male Ross 308 broiler chicks were
randomly allotted to three dietary treatment groups (4 replicates per group, 40
birds in each replicate): an antibiotic-free corn-soybean meal basal diet (NC);
basal diet + enramycin 0.01% (PC); and basal diet + 0.1% SLCPP (SPP). The
experiment lasted for 35 days. Results showed that birds fed with SLCPP had
higher body weight (BW) and average daily gain (ADG), and lower feed conversion
ratio (FCR) during the grower phase (days 7 to 21) (p <
0.05). Except for blood urea nitrogen, all other blood biochemical parameters
remained unaffected by the dietary supplementation of SLCPP. Compared to the
control group, lengths of the duodenum and ileum in the SPP group were
significantly shorter (p < 0.05). Moreover, counts of
lactic acid bacteria (LAB), total aerobes, and Streptococcus
spp. in jejunum as well as LAB in cecum were increased in the SPP group than in
the PC group (p < 0.05). These results suggest that
dietary supplementation of SLCPP might promote the growth of broilers in their
early growth phase. |
