SIAM NOVAS CO., LTD.

Siam Novas Co. Ltd. evolved out of the Immunology & Reproductive Physiology Research Unit (IRPR), Department of Animal Science, Faculty of Agriculture, at Chiang Mai University in northern Thailand. This research unit was managed by Assoc. Prof. Petai Pongpiachan. His team included Assist. Prof. Dr. Korawan Sringarm and Assist. Prof. Dr. Wiwat Pattanawong, who were both his former graduate students and research assistants, plus other graduates who took part in the research projects run by the IRPR. At this stage, it is evident that from the experiments with 943 cows, the ratio to produce a female calf is in the range of 71 – 80 %, which is satisfactory commercially. This technology is, therefore, ready to be exploited in both domestic and international markets. The estimated word demand for frozen semen is over 300 mn dosages per year, which is worth more than 90 bn Bath.

SIAM NOVAS

Our vision: To create innovations for both domestic and international farmers by our products called “Siamhero”.

Our Products & Services

We produce cattle sexed semen for dairy and beef and offer our partner by way of an Original Equipment Manufacturer (OEM) at a reasonable price.

THE INNOVATION

By nature, the ratio of male to female calves is 50:50. Chromosome X (X-bearing spermatozoa) determines the female and chromosome Y (Y-bearing spermatozoa) generates the male. Our innovation reduces the ratio of chromosome Y through a process of monoclonal antibody on the antigen. At present, we can bias the ratio, on average, to over 75 % in favor to the female calf.
