Probiotics

Probiotics are defined as live microorganisms, including Lactobacillus species, Bifidobacterium species and yeasts that may beneficially affect the host upon ingestion by improving the balance of the intestinal microflora of animals.

Introduction

The concept of probiotics and the use of these products as feed additives has been developing since the late 1970's but has become more popular in animal feed particularly poultry and aquaculture after the ban of in-feed antibiotics on January 1st 2006.

Even though the new feed regulation 1831/2003 makes it more difficult for companies to put their products on the market, the probiotic business is growing rapidly.

The reported benefits of feeding live organisms include decreased occurrence and duration of diarrhoea, immunostimulation, pathogen resistance and maintenance of mucosal integrity.

How probiotics are able to exert so many positive effects is still not fully understood and may be a combination of many factors where the most widely accepted mode of action is that of competitive exclusion.

While the benefits of probiotics are generally accepted, there are still many questions concerning their mechanisms. This has always been a difficult topic of research because of the huge of variability of the different trials, not only concerning the subject animals and their environment, but also involving different preparations of the probiotics themselves.

Probiotics have potential to produce beneficial effects in poultry via modifications of the microbial population within the digestive tract. Read more >
