In Jakarta, Jillian Yarnell, technical support manager with Pacific Vet Group, recently discussed probiotic for poultry.
In the criteria of isolates (bacteria) of probiotic, Yarnell said that isolates of probiotic must produce heat resistant spores. “Isolates of probiotic should be resistant to heating at 100oC for 10 minutes. And the viability of the spores only slightly decline when feed is processed by pelleting,” she explained.
In addition, Yarnell continued, isolates of probiotic should have a high proliferation rate, efficient sporulation, in-vitro activity against pathogenic micro-organisms in the digestive tract and meet the requirements of GRAS (Generally Recognised as Safe). Isolates of probiotic that have met the requirements of GRAS are Bacillus coagulans, Bacillus lentus, Bacillus licheniformis, Bacillus pumilus and Bacillus subtilis.
Specifically in poultry, said Yarnell, “There are some specific criteria of isolates of probiotic. Isolates of probiotic must be able to reproduce and to work synergistically in the digestive tract of poultry, as well as to be able to bring out the best performance in reducing the number of pathogenic micro-organisms in the digestive tract of poultry.”
At the same time, Pacific Vet Group also launched its probiotic product for poultry, Sporulin. Sporulin is a spore-based Bacillus subtilis probiotic which has benefits on reduction of pathogens such as Salmonella, reduction of necrotic enteritis and improvements in average daily gain and feed efficiency.
On Sporulin dosage, Yarnell informed that to obtain a total of 106 spores per gram, Sporulin is mixed in feed at a dose of 250 grams per tonne of feed.
