Abstract |
The aim of the study was
to evaluate the effects of different progestagens on oestrus synchronization and the effects of vitamin mix (A, D3 and E)
and GnRH
singly or in combination on the
fertility parameters in
anoestrus dairy
goats.
The animals (n=186) were
divided into three groups. One group was injected with 20 mg
fluorogeston acetate, second received
60 mg
medroxyprogesterone acetate and third was treated with 3 mg Norgestomet.
The goats which showed oestrus with these
applications were further mated naturally.
For this purpose, the goats were divided into four
subgroups. The control
goats
received 2 ml NaCl, second group was treated with
vitamins (150,000 IU D3, 1,000,000 IU A and 100 mg E) immediately after
mating, third group was treated with GnRH on the 12th day after mating
and the fourth group received the combination of vitamins and GnRH.
The oestrus rate and the
interval to oestrus
were found to be higher (P<0.05) in experimental goats treated with
Norgestomet. There were no statistically significant differences between
the subgroups in terms of the pregnancy
rate, abortion rate, gestation length, twins rate and
litter size
(P>0.05).
In conclusion, the short term applications of
FGA, MAP and Norgestomet successfully induced oestrus
in
anoestrus dairy
goats successfully. However, the vitamins and GnRH
administrations post-mating did not improve the fertility parameters.
