Skystar Bio-Pharmaceutical Company announced preparations to launch a new probiotic product for dairy cows by the end of fiscal 2014. The dairy cow probiotic is developed for the milk production industry in China and is designed to introduce Bacillus Subtilis (B. subtilis), also known as "Hay Bacillus," into the digestive tract of milk producing cows. Hay Bacillus has been proven to aid in the digestion and breakdown of hay in the animals' rumen canal.

Skystar's dairy cow probiotic is expected to launch at the end of the fiscal year and is a welcome addition to Skystar's Western medicine-based line of animal husbandry products. Currently, the demand for milk outpaces domestic supply in China and as a result consumers are buying imported dairy products such as powdered milk to meet the shortfall. B. subtilis natto is produced from soybeans fermented with B. subtilis.

There have been a number of major dairy experiments with good results. The conclusions have included improved milk production and milk components yield, decreased somatic cell count (a metric for milk quality) increase of total ruminal bacteria and increase of proteolytic and mylolytic bacteria. Results of trials introducing B. subtilis natto to the gut flora have demonstrated, among others: Anti-inflammatory properties; Anti-stress and fatigue, enhanced immune system, improved vaccine protection force and the protection rate; Increased milk production and milk quality; Improved digestion and absorption of feed; Improved rumen environment and rumen buffering capacity, promoting the growth and metabolism of rumen microorganisms, stable rumen pH, thereby improving rumen absorption of volatile fatty acids (VFA).
