Description: 

Efficiency is the name of the game, and anything you can do within your hog operation to step up production helps drive dollars to your bottom line. That’s why it’s always important to stay active on the front line when combating one of the swine industry’s most-costly viruses — porcine reproductive and respiratory syndrome virus (PRRSV). Instead of accepting defeat, you can step up your defense against PRRSV. Daily feeding of an effective probiotic has been shown to positively impact the ability of pigs to respond favorably to an encounter with PRRSV.

A study, funded by Chr. Hansen in 2019, examined the effect of daily feeding of a two-strain probiotic combination — Bacillus subtilis (DSM5750) and Bacillus licheniformis (DSM5749) — to sows beginning 31 days pre-farrowing through weaning on their lactation and on the performance of their litters. The research also sought to determine the effect of continued daily feeding of the Bacillus strains DSM5750 and DSM5749 to piglets for an additional 28 days after weaning amid a severe challenge with PRRSV.

At the end of the four-week trial period, with daily feeding of an effective probiotic, we saw a significantly greater percentage of animals that survived the challenge and that thrived in the post-challenge period, resulting in better rates of feed conversion and gain for the treated group. In studies like this, we’re finding that effective probiotics help support an animal’s normal gut functions, even in the presence of severe challenges faced by the industry day in and day out.
