Abstract

Despite the variety of hormonal treating regimes used, a proportion of cows with cystic ovarian disease (COD) fail to be cured. The hypothesis of this study was that cyst aspiration would improve the curing rate and/or accelerate the resumption of ovarian activity in affected cows. In four groups of cows the following treatments were administered: Group A (n = 18) only cyst aspiration, Group AGP (n = 19) cyst aspiration and a combination of GnRH and PGF2α, Group GP (n = 25) only GnRH and PGF2α, and Group C (n = 15) untreated control. Cysts were aspirated without ultrasonographic guidance, using a new device. All cows from Group AGP responded to treatment, while 5.5% from Group A and 16% from Group GP remained anoestrous (P < 0.05). These refractory cases were re-treated with the AGP protocol and exhibited oestrus within 12.4 ± 1.1 days. The interval from PGF2α injection to oestrus was significantly reduced in cows treated with cyst aspiration. Until day 80 post partum (pp), 11 of the 15 untreated cows (73.3%) retained the initial cyst and remained anoestrous. It is concluded that persisting cases of COD can be treated by combining aspiration with a hormonal regime. The technique presented here has no complication for the cow, is efficient, easy, safe for the operator, and requires low-cost equipment.
