Bovine Polyclonal Anti-eCG and eCG Combinated Vaginal Sponges Progesterone to Induce Estrus and Pregnancy of Etawa Crossbred Goats

Abstract

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 PGF2? 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 PGF2? and 300 IU of eCG. T2 were injected in
all the goats 7.5 mg of PGF2?, 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.
