Sihtrühmad

  1. Ülikoolid, teadlased.
  2. Piima- ja lihaveisekasvatajad

 

Kasutusvaldkonnad

  1. Veiste sigimisfunktsiooni uurimine.
  2. Veiste sigimise majandamine (mittetiinete lehmade varane avastamine, poegimisjärgselt innatsüklite taastumise kindlakstegemine, munasarjade funktsioonihäirete diagnostika, füsioloogiliselt valel ajal tehtud seemenduste osatähtsuse kindlakstegemine, inna avastamise efektiivsuse kindlakstegemine).

 

Nõustamine

Anname nõu, kuidas piima progesteroonisisalduse määramise abil välja selgitada lehmade suboptimaalse sigimisrütmi põhjuseid ja kuidas lehmade sigivust paremini majandada.

 

Analüüsimeetodi kirjeldus

            Piima progesteroonisisaldust analüüsitakse monoklonaalsel antikehal põhineva ensüümimmunoloogilise (EIA) meetodiga. Analüüsis kasutatav progesteroonispetsiifiline monoklonaalne antikeha on spetsiaalselt valitud progesteroonisisalduse kvantitatiivseks määramiseks lehma piimast (Waldmann, 1999). Progesteroonispetsiifilise monoklonaalse antikeha kasutamine kindlustab nimetatud meetodi kõrge tundlikkuse, spetsiifilisuse ja usaldusväärsuse. Võrreldes piima progesteroonisisalduse teiste määramismeetoditega, ei sõltu nimetatud meetodi tulemused piima rasvasisaldusest, võimaldades analüüsida erineva rasvasisaldusega proove ja saada täpsemaid tulemusi. Meetodit on kasutatud lehmade sigimisfunktsiooni uurimiseks Eestis, Norras, USA-s ja Tansaanias.
