Abstract
The study was undertaken from May 2017 to April 2018 at the
clinical unit under Department of Animal Reproduction, gynaecology and
Obstetrics of University Veterinary Hospitals, Mannuthy and Kokkalai and
Goat and Sheep farm, Mannuthy by ultrasonographical screening of does
with an objective of diagnosis and therapeutic management of
pseudopregnancy in goats at an early stage (Group I) and to compare the
conception rate with that of normally cycling does (Group II). Group I
animals (with anaechoic uterine sacculations separated by tissue trabeculae)
were treated with double regime of PGF₂α analogue on day of detection of
pseudopregnancy and 12 days later and response to treatment and oestrus
characters were studied and were subjected to natural service on induced
oestrus on consecutive days, whereas group II animals were served on the
first observed oestrus after selection. Of the 1162 animals screened, the
occurence of pseudopregnancy was found to be 1.98 per cent only. Using
ELISA technique, serum progesterone levels were estimated and the mean±
SE progesterone levels on the day of diagnosis of pseudopregnancy in group
I was 6.98±0.56 ng/mL and that of pregnant animals on the same stage postservice in group II was 8.04±0.56 ng/mL and they differed non-significantly.
All the animals responded well to the double regime with PGF₂α.
Confirmation of pregnancy was assessed by ultrasonography on day 45 postservice. With the first natural service, the conception rate in group I was
71.42 per cent whereas in group II was 90 per cent.
The present study revealed that ultrasonography can be
effectively used for early diagnosis of pseudopregnancy in goats and double
regime treatment with PGF₂α analogue and breeding on consecutive days on
induced estrus are effective in management of pseudopregnancy by
minimising the chances of recurrence and improving the further fertility rate.
