Abstract

The objectives of this study were to compare FERTILITY between HEATSYNCH and ESTRADOUBLESYNCH protocols in fresh Holstein DAIRY COWS. Holstein cows with normal ovary and uterus (n= 191, yielding more than 30 kg of milk/d and parity 3.2±1.1) were randomly assigned into two experimental groups, including 1- HEATSYNCH (n=96), GnRH-7d-PGF2 a -24h-EB-48HTAI or 2) ESTRADOUBLESYNCH (n=86), PGF2a-2d-GnRH-7d-PGF2 a -24h-EB-48h- TAI. Results showed that ESTRADOUBLESYNCH increased the percentage of cows diagnosed pregnant cows at 32 and 60 d after AI (P<0.05). Conception rate was greater in ESTRADOUBLESYNCH compared to HEATSYNCH protocol at d 60 after TAI. Pregnancy loss was lower in ESTRADOUBLESYNCH compared to HEATSYNCH protocol (P<0.05; 8.81 vs. 19.23 % for HEATSYNCH and ESTRADOUBLESYNCH protocols, respectively). Mean (± SEM) diameter (mm) of ovulatory follicle at the time of TAI was larger in HEATSYNCH (19.2±0.32) than ESTRADOUBLESYNCH (17.1±0.19). In conclusion, ESTRADOUBLESYNCH resulted in younger ovulatory follicle compared to HEATSYNCH and causes higher conception rate as well as lower pregnancy loss in this group.
