Study on luteal tissue treatment in angus cows with natural and synthetic analogue of prostaglandins

Abstract

The objective of this study was to evaluate the effects of prostaglandins (natural and synthetic analogues) on estrous synchronization in beef cows. The study was carried out between May – August 2019 in a private unit in Timis County, and involved 54 Aberdeen Angus cows diagnosed with ovarian luteal tissue: corpus luteum (n=36 cows), cystic corpus luteum (n= 8 cows) and luteal cysts (n=10 cows). Two products were used for the treatment of this pathology: PGF Veyx Forte (n=27 cows) and Enzaprost (n=27 cows). The interval between hormonal treatment and the onset of estrous was ranging from 48-96 hours. In this trial 83.33% of the animals expressed signs of estrous. In the present experiment the conception rate after the artificial insemination was 71.11%.
