Animal probiotics is widely accepted today, and the rapidly advancing technology related to molecular biology and gene sequencing is aiding researchers dig deep to explore novel probiotic applications for animals, such as in consumer-packaged health products and in feed for companion pets. Over time, livestock and cattle farmers have increased the adoption of animal probiotics for commercial animal feed for poultry and cattle to change the gastrointestinal flora, which continues to trigger the sales of animal probiotics, impacting the animal probiotics market in a positive way.
