Effect of different oestrus synchronization protocols on serum macro and micro minerals of surti goats

Atotal of 18 non-pregnant Surti goat were selected and divided into 3 groups (n=6). Goats in G1 were treated with intravaginal progestogen sponge (60 mg medroxyprogesterone acetate) along with GnRH analogue (buserelin acetate (Receptal® VET @ 0.0042 mg intramuscular) on day 0, natural PGF₂ α analogue (dinoprost tromethamine; Lutalyse® @ 10 mg) on day 9 and 2 ^nd injection of GnRH analogue on day 11 after removal of sponges. Goats in G-2 were treated in the same way as G-1 except for intravaginal progestogen sponge. Goats in G-3 were as kept control and injected with 2 ml normal saline. The serum macro mineral (calcium and phosphorus) and micro mineral concentrations (copper, iron and zinc) of Surti does did not differ significantly (P>0.05) among the groups at 0^th day, 5^th day, 11^th day of oestrus and 30^th day post oestrus. It was concluded that gonadotropin-prostaglandin-gonadotropin (GPG) synchronization protocols with or without intravaginal progestogen sponge in Surti goats did not influence the serum macro and micro mineral levels.
