Bacillus subtilis-containing feed

枯草菌含有飼料 子豚

Bacillus subtilis-containing feed
One of the most common microorganisms in probiotic products is Bacillus spp.  Bacillus spp. is known to be normally present in the intestinal tract of healthy animals. In addition, it is a highly heat-stable microorganism, can survive when passing through the stomach and it has been found to adhere to the host GI mucosa.

 

The following beneficial effects are considered

  1. Change intestinal flora and reduce E. coli
  2. Synthesize lactate and lower the pH in the intestine
  3. Adhesion or colony formation in the digestive tract
  4. Formation of antibiotic-like substances
  5. Produce various enzymes in the digestive tract
  6. Reduce levels of harmful amines and ammonia in the digestive tract

Effect on animals

  1. Improve digestibility
  2. Increase body weight, improve feed efficiency
  3. Reduction of feed costs
  4. Improving the health status of piglets and sows
  5. Declining mortality rate before weaning
  6. Increase in piglet production per sow

Our Probiotic BioPlus YC is a microbial feed additive that is evenly mixed by spray drying with spores of Bacillus licheniformis (DSM5749) and Bacillus subtilis (DSM5750). It is registered in the EU as a product. (EU reg. no. E1700) for pigs, calves and chickens.
