The problem of early pregnancy testing costs billions of dollars. In current conditions the breeding is
mainly artificial but still does not allow to reach rate after fertilization more than 60-65%. (2) Earlier you
detect non-pregnant cows, so earlier youl do one more breeding to achieve higher rate. Dairy and meat
farms incur large financial costs in the preparatory period and when feeding pregnant animals in the period before fertilization is confirmed. The methods today widely used to detect bovine non-pregnancy
are well described in movie below.
Project Aim: Development of an easy-to-use cheap rapid cattle pregnancy test to increase the efficiency of its reproduction due to early detection of the bovine non-pregnancy.
The most adequate method of non pregnancy detection - is progesterone level detection. (6) It gives the
results оn 21 day and gives very precise results in non-pregnancy detection. But currently the cost to
Our Solution: There is a demand on cheap (<$1,5) PoC milk express method for determining the cow's
pregnancy on 21 day after the breeding which will reduce the cost during a false pregnancy. The existing techniques and design to develop PoC chromatography devices could not reach need prices (11) which are higher $6.
We are developing a cheap paper chromatography device which will allow to non - professional farmer
himself monitor the progesterone milk level and to invite veterinary specialist to perform blood tests in heifers only. The next stage we shall develop the paper chromatography blood test also for heifers.
Competing: There were several attempts to create PoC devices for on farm progesterone testing (7, 8, 9) based on lateral flow design(10). There are the attempts to create human like pregnancy test based on
very difficult and you can look movie below to get a fun with such procedure.
