Twin pregnancies are one of the most important factors affecting the finances of dairy cattle farms as they have a high rate of pregnancy loss compared with single pregnancies, and, if twins are born, the indirect costs increase dramatically. Among others, the animal elimination rate increases (reducing the average life of the animal at the farm) as does expenditure on anti-inflammatory and antibiotic drugs to reduce postpartum illnesses.
For this reason, attempts are being made worldwide to implement different techniques to reduce the associated negative impacts, such as the manual rupture of one of the amniotic vesicles during the 28-41 days following artificial insemination (AI), or an ultrasound-guided technique of follicular drainage of one of the two follicles present at the time of AI. Although both techniques work acceptably well, the former increases pregnancy loss possibly due to the placental anastomoses of this species. However, the technique of ultrasound-guided follicular puncture reduces twin pregnancies and increases additional corpora lutea (CL), but cannot be carried out at the rate of a weekly reproductive visit and, moreover, the material required is costly. Recently, a technique using ultrasound-guided follicular puncture has been described that can be conducted at weekly reproductive visits. It is very similar to the Ovum Pick Up but without ultrasound.

This has a very high impact on the economy of the farm, on the welfare of the animal and on reducing the use of antibiotics postpartum.
