Bovine polyclonal anti-ecg and ecg combinated vaginal sponges progesterone to induce estrus and pregnancy of etawa crossbred goats

Equine chorionic gonadotropin (eCG) like folligon is a gonadotropin hormon derived from blood sera in pregnant mare 30 till 140 days. The repeated use of eCG treatments for the induction of ovulation is generally followed can decrease in fertility. Bovine anti-eCG antibodies (Abs) as research result in Universitas Airlangga in 2019 can solve the problem of decrease in fertility in does. The objective of this study was to evaluate the reproductive performance of subjected to a short-term protocol for estrus induction using 50 mg of vaginal sponges’ progesterone. The experimental animal used in this study comprised of 30 etawa Crossbred goats, with normal estrus cycle and 3 years old of age. The etawa crossbred goat are all healthy with a body score of at least three. 30 goats divided become 3 groups Group I as (T0) 10 goats are as controls Groups. (T0) was inserted sponge progesterone 50 mg of MPA and injected with PGF2α 7.5 mg in day 10 intramuscular (im) when T0 removal of the sponge were removed on day 11. Does on day 11 as T1 going on the removal of devices 24 h before removal inject 7.5 mg of PGF2α and 300 IU of eCG. T2 were injected in all the goats 7.5 mg of PGF2α, 300 IU of eCG at day 10 and 300 IU bovine anti eCG inject at day 11 when removal device on day 11. After 35 days, pregnancy was diagnosed by ultrasound scanning. Short-term protocols using either an intravaginal device was similarly effective to estrus induction 100% p >0.05, and all goats from both groups had estrus manifestation within 30 h after device removal, duration of estrus 37 h and doing AI. In addition, no significant difference in pregnancy p >0.05 on 35 days.
