Hyperprolific sows face vital challenges, together with elevated susceptibility to dysbiosis and oxidative stress, which impression each their well being and the survival of their piglets. Diet performs a key function in mitigating these results, with probiotics rising as an efficient instrument to reinforce intestine well being, immunity, and total efficiency.
Goal: On this examine, we explored the potential of a probiotic complement containing Bacillus subtilis and Bacillus amyloliquefaciens as a dietary additive for sows throughout gestation and lactation.
Strategies: A complete of 584 sows had been included within the trial, divided into two teams: one receiving a normal weight loss plan and the opposite supplemented with 400 g/ton of the probiotic. Sows adopted a structured feeding program with three weight loss plan phases: early gestation (1–28 days), mid-to-late gestation (29–90 days), and a shared prepartum-lactation weight loss plan (91–115 days). Feed consumption, physique weight, and backfat thickness in sows had been monitored, whereas piglets had been weighed at beginning and weaning. As well as, numerous well being and immune parameters had been examined, together with fecal scores, salivary cortisol ranges in sows, and immunoglobulin concentrations in each blood and colostrum. In piglets, ileal histomorphometry was evaluated, together with bacterial counts and myeloperoxidase exercise in feces to evaluate intestine well being and immune response.
Outcomes: Sows supplemented with probiotics skilled higher weight reduction throughout lactation however produced extra milk. Whereas no variations had been noticed in backfat thickness, feed consumption, or reproductive parameters, piglets from probiotic-fed sows had an extended lactation interval, larger weaning weights, and required much less treatment. The probiotic group additionally had fewer piglet deaths as a consequence of crushing. Salivary cortisol ranges had been larger earlier than farrowing however decrease postpartum in probiotic-treated sows, indicating lowered stress. Though colostrum and serum immunoglobulin ranges remained largely unchanged, probiotic-fed sows had elevated fecal Bacillus sp. counts. Their piglets confirmed improved intestine well being, with decrease pathogenic micro organism counts and better myeloperoxidase exercise by day 17.
Conclusion: Total, including this probiotic complement to sow diets positively influenced each maternal efficiency and piglet well being, supporting its use as a helpful dietary technique in swine manufacturing.
