Abstract

An Enzyme Immuno Assay for Progesterone, using horse radish peroxidase as the label, was adapted for direct measurement of progesterone in milk. This was carriedout to detect early pregnancy in cows. The experiment used sixty milking cows divided into three groups, one as a controland two others as treatment groups. In group I (control) milk samples were collected on the day of insemination to 24 days afterward by quartan collection. In group II, milk samples were collected on days 18, 21 and 24 after insemination. In group III, milk samples were collected on days 21 and 24 after insemination. Milk samples were collected from lactating cows at noon from four quarters and preserved with Potassium dichromate (Merck 4858), stored at - 20 degree C until analysed.Pregnancy diagnosis by EIA was confirmed by rectal palpation at 60 to 90 days after insemination. The early pregnancy diagnosis in Group II compared with Group III showed that prolonged the time of sampling indeclinable improved the acuracy.

Abstract

Determination of reproduction status was carried out 16 lactation dairy coes at Faculty of Veterinary of Animal Science - IPB by measurement of milk progesteron level by Enzyme Immunoassay.This result could concluded that : oestrus, post oestrus and pregnant, respectively, where as 7 cows were oestrus, I Cow post oestrus, 3 cows dubius pregnant and 5 cows pregnant. Comfirmation by rectal palpation was done one week later and shown that : 4 of 5 diagnosed pregnant, I cows need recheck.The accuracy of milk progesteron assay by Enzyme Immunoassay (EIA) in this case was 80% for positive pregnant.
