The early detection of pregnancy and the determination of fetal numbers have economic benefits in sheep production because of the seasonal breeding patterns where missing a breeding opportunity means the loss of one productive year. The purpose of this study was to evaluate the efficacy of the B6-HRP ELISA for ovine pregnancy-specific protein B (oPSPB) measurement in the detection of pregnancy and estimation of fetal numbers in different sheep breeds. BioPRYN® ELISA assay kit was used for the detection of pregnancy in the experimental animals.

Article Synopsis
  • The study aimed to assess the impact of administering low doses of slow-release recombinant bovine somatotropin (bST) on hormone levels, embryo development, and fertility in dairy cows after they gave birth.
  • Cows were divided into three groups: a control group with a placebo, one group receiving a single bST injection, and another receiving two injections of bST, with various hormone levels and pregnancy outcomes monitored throughout the study.
  • Results showed that cows receiving two doses of bST had better hormonal responses, larger embryo sizes, and improved fertility compared to those receiving just one dose or a placebo, confirming the benefits of bST in enhancing reproductive success in dairy cows.

The objective of the present study was to compare two commercially available blood-based pregnancy tests, namely BioPRYN, an ELISA for pregnancy-specific protein B (PSPB), and an ELISA for pregnancy-associated glycoprotein (PAG), for early pregnancy diagnosis in dairy cattle using transrectal ultrasonography as a gold standard. Transrectal ultrasonography was conducted 26-58 days after artificial insemination (AI) in 197 cattle from 19 farms. Concurrently, a blood sample was collected for determination of serum PSPB and PAG.
