| description | Accurate pregnancy diagnosis is an important criterion and management tool for successful dairying. Early identification of non-pregnant dairy heifers and cows after breeding can improve pregnancy rate and life time production. Determination of progesterone hormone levels is more accurate to diagnose failed pregnancies in dairy animals. This method is not always available in developing countries. Some of the kits available are developed for humans and might be used for cattle because in principle, progesterone is not species-specific and detection methods are the same in both animals and human beings. The study aimed at validating a human progesterone ELISA kit for use in cattle as a pregnancy diagnosis tool. Forty Boran and crossbred cattle (22 pregnant and 18 non-pregnant) were selected for the study. Ten milliliter of blood sample was collected from each animal using jugular venipuncture. Serum I and plasma was harvested within 2 hours after venipuncture and serum II after 12 hours, and all samples were analyzed for progesterone concentration using the ELISA procedure provided with the kit. The result showed that 88.9% (n = 16) of non-pregnant cows had progesterone concentration below 1 ng/ml with mean (±SE) of 0.48 ± 0.75 ng/ml while all pregnant cows had mean (±SE) concentration of 19.3 ± 0.68 ng/ml with individual values ranging from 5.2–38 ng/ml. Progesterone concentration between breeds and sample type did not show statistically significant difference for pregnant and non-pregnant cows. Nonetheless, the results of the experiments are very promising as far as pregnancy diagnosis is concerned in dairy cows from an economic perspective and accuracy; the experiments have to be performed on larger scale to proof repeatability and sensitivity |
