Use of probiotics for grower-finisher pigs for improvement of performance is possible, never-the-less, probiotic products might not be what first comes to mind when thinking about feed additives for grower-finisher pigs. Especially not these days where feed costs are high and adding more costs to the diets must be considered carefully.
However, a recent study was done on a probiotic product combing Bacillus licheniformis and Bacillus subtilis fed to grower-finisher to evaluate the effect on gut microbiota and performance such as feed conversion ratio (FCR) and average daily weight gain (ADG). Furthermore, also carcass and meat quality were examined.
The authors conclude that the probiotic product had significant effect on the gut microbiota positively affecting the fattening results, mainly through a reduction in mortality and improvement in FCR and ADG. No significant effect was found in carcass and meat quality.

Probiotics as a technology to lower antibiotic use according to a recently published literature review.
A literature review conducted by the University of Bologna (Italy) on how probiotics can limit the use of antibiotics was published. 131 scientific papers were included in this publication evaluating the effectiveness of bacillus-based probiotics on a broad array of modes of action such as having a positive effect on the gut microbiota, gut integrity, immune-modulatory actions, and performance of pigs and chickens.
The review concludes that bacillus-based probiotics can reduce post-weaning diarrhea by 30% as well as improve performance parameters such as average daily gain and feed conversion ratio. The authors further conclude that bacillus-based probiotics can be a potential technology for lowering the need for antibiotic use in pig production.
