MAJOR ACTIVITIES OF EACH UNIT

Sl.No UNIT ACTIVITY

1 LARGE ANIMAL GYNAECOLOGY UNIT

This unit attends to pregnancy diagnosis and treatment

of infertility problems (Anoestrum, Repeat breeder,

Cystic ovaries, Endometritis etc.,) in both large and small

ruminants. Early pregnancy diagnosis using

ultrasonography is also being routinely done.

2 ARTIFICIAL INSEMINATION UNIT

This unit performs artificial insemination in goat, cows

and buffaloes that are presented to the hospital.

3 LARGE ANIMAL OBSTETRICS UNIT

This unit attends to cases that are presented with Pre-

partum complications, dystocia and post-partum

complications such as total uterine prolapse, retained fetal

membranes and metritis etc., in cows, buffaloes and goats.

Cesarean operation is also being performed in both cattle

and goat.

4 SMALL ANIMAL OBSTETRICS AND GYNAECOLOGY

This unit attends to cases such as pregnancy diagnosis,

Breeding advice, whelping and its complications,

abortion, pyometra, pseudopregnancy and medical

termination of pregnancy in bitches, semen evaluation

and infertility in dogs.

5 SMALL ANIMAL OPERATION THEATRE

This unit attends to regular castration and spaying in both

dog and cats. In addition, all surgeries related to

reproductive problems such as C-Section and OHE are

also being performed.

6 ASSISTED REPRODUCTIVE TECHNOLOGY LABORATORY

This lab has the facility to perform in vitro fertilization

and embryo cryopreservation in both small and large

ruminants.

LARGE ANIMAL ARTIFICIAL INSEMINATION AND GYNAECOLOGY UNIT AND MOBILE AI

During the year 2011-2012, Artificial Inseminations have been carried out in 919 cows,

143 buffaloes and 11 goats and 820 cases have been treated at the large animal Gynaecology

unit for various reproductive disorders, of which Repeat breeding and anestrum were the major

infertility problems encountered.

• Synchronization of estrus and ovulation is being done using the CIDR which involves

insertion of CIDR on day 0, Inj. PGF2α on day 8, removal of CIDR by day 9 and timed AI

on day 11 and 12. Pregnancy diagnosis in cattle, sheep and goats is being done using

Ultrasonography.

• Sexing of the fetus in cattle and buffaloes is done using ultrasonography

• Accurate timing of insemination in cattle is being determined based on the vaginal

electrical resistance using Heat detector. In addition, the staff of this department attend to

the AI mobile unit wherein 381 cows in and around the city have been inseminated.

• In cases of repeat breeder cows, white side test, endometrial cytology and endometrial

biopsy is being performed to detect subclinical endometritis and to ascertain the status of

endometrium. Vaginal exfoliative cytology is being done to identify estrus in goats brought

for AI

LARGE ANIMAL OBSTETRICS UNIT

During the year 2011-2012, 1301 cases were treated for pre, peri and post partum

complications in bovines and goats of which, the frequently encountered conditions are retained

fetal membranes, metritis, uterine torsion and dystocia due to fetal malpresentation and posture.

SMALL ANIMAL OBSTETRICS AND GYNAECOLOGY UNIT

During the year 2011-2012, 2674 cases were examined for various reproductive disorders.

The most common conditions encountered are Breeding advice, anestrus, misalliance, pregnancy

diagnosis, pseudopregnancy, pyometra, dystocia etc. Among the cases examined, bitches brought for

breeding advice, pregnancy diagnosis and for treatment of pyometra were higher in number.

SMALL AND LARGE ANIMAL REFERRAL UNIT

• In the small and large animal referral unit, vaginal exfoliative cytology, vaginoscopy,

ultrasonography, semen analysis and artificial inseminations are being carried out.

• 1663 large and small animal reproductive ultrasonography have been performed and the

total revenue generated was Rs.1,48,000/-

• Around 900 vaginal exfoliative cytology were carried out (including canine, caprine and

others) and total revenue generated was Rs. 36,700/-

• Prediction of gestational age and fetal sexing of bovine fetus is being standardized.

• Prediction of gestational age using placentome diameter in goats is being standardized

• Ultrafast Peroxidase Antiperoxidase (PAP) stain is used for staining vaginal exfoliative

cytology smears for identification of estrus in goats.
