| Sumario: | Piglets are born without a developed immune system and different types of bacteria colonize
the piglets’ gastrointestinal tract directly at birth. Maintaining a healthy microbiota in the
intestinal tract is important for the piglet to be resistant to pathogenic bacteria and thus reduce
the incidence of diarrhea as well as promoting growth.
This study investigated whether probiotic bacterial strains of the species Lactobacillus
plantarum and Lactobacillus reuteri could have a positive effect on growth performance,
health and microbiota in piglets. Different methods of administration were compared to evaluate
which gave the best effect on the above parameters. The study involved 599 pigs which
were divided into six different groups. The methods of administration compared were oral
supplementation to the piglets, oral supplementation to the sow, spray on the sow's udder
and supplementation in piglets’ peat. The piglets were supplemented with probiotics during
the suckling period, the pigs that received probiotics in peat also obtained it for two weeks
after weaning. In addition to these administration groups, there were two control groups: one
group that received no supplement at all and a control group that only received probiotics
after weaning (in the peat). The weight of the piglets was documented at 15, 36, 43 and 49
days of age and a health form was filled out for each piglet at each time of observation. At
49 days of age, fresh faecal samples were taken from 35 of the pigs to analyze if there was
any difference in the number of Lactobacillus and Enterobacteriaceae between different
administration groups.
The results showed no clear pattern between the administration groups regarding growth
performance or microbiota. At 49 days of age, the group that received probiotics by spray
on the sow's udder during the suckling period had significantly higher mean weights than
the group that received probiotics only after weaning. The pigs who received probiotics i n
the peat after weaning had a significantly lower daily growth compared to the pigs who did
not receive supplementation in the peat after weaning. There was no significant difference
in the number of Lactobacillus and Enterobacteriaceae between administration groups. In
conclusion, no visible effect could be seen in piglets’ growth performance or microbiota
receiving probiotic supplement. At present, there are no studies comparing different methods
of administration of probiotics to piglets during the suckling period. More research on the
effect of probiotics on piglet’s health and how probiotics can be most efficiently administrated
is needed. |
