Research Projects in Operation:
1.
Use of elite buffaloes
for production of quality embryos in vitro and their use for genetic
improvement
Salient Achievements:
1. Embryo Biotechnology
i.
The Department is pioneer in initiating embryo transfer work in
rabbit and goat in the year 1976.
ii.
Initial trial of surgical transfer of goat embryos revealed 63.50%
embryo survival. Goat embryos were also frozen using 2.00 MDMSO.
iii.
Super-ovulation studies were performed in buffalo using PMSG.
iv.
Super-ovulation, non-surgical embryo collection and non-surgical
embryo transfers were performed for standardization of various aspects
of embryo transfer technology including pregnancy rate in Sahiwal and
Crossbred cows. Several Sahiwal and Crossbred calves, including seven
calves from one cow, were produced.
v. Research trials were conducted to study effect of various gonadotropins and endocrine profile during superovulatory estrus to
improve superovulatory response and embryo recovery. The mean total
and viable embryo recovery of upto 5.25 and 1.80 per flushing,
respectively was achieved. In Sahiwal cows, the mean ovulation rate,
total and viable embryo recovery was observed to the 9.76, 3.52 and
1.67, respectively.
vi.
The mean pregnancy rate on transfer of fresh and frozen embryos was
23.80 and 36.40%, respectively. The improved conception was observed
with GnRH treatment to recipients on day 5 and also with transfer of
fresh embryos of excellent grade (upto 76.90% conception).
vii.
Extensive studies ware made to study in-vitro maturation (IVM) and
in-vitro fertilization (IVF) of oocytes, in vitro capacitation of
sperm, and in-vitro culture (IVC) of embryos using various media and
co-culture systems to study the media requirement for oocytes/embryos
of different stages. Immature oocytes were also vitrified successfully
using different cryo-protective agents.
viii. The technique of biweekly collection of ultrasound guided
trans-vaginal oocyte aspiration (ovum pick-up) in Sahiwal cows has
been established and embryos are being produced using IVM/IVF and IVC
technology.
2. Semen Biotechnology
Extensive studies were undertaken in
the area of Andrology, Artificial Insemination and
Semenology including qualitative and quantitative
aspects.
i. Studies on Semenology aspects of Crossbred bulls of
different breed/genetic Friesian are not good producers, especially
when the exotic inheritance increased more than constitution revealed
that Crossbred bulls having exotic inheritance of Red Dane and
Holstein-62.50%. Crossbred bulls with 50.00% exotic inheritance were
better. There was non-significant effect of seasons on semen
production potential of these bulls.
ii.
Different modifications of egg yolk tris dilutor (EYT) were
successfully developed to cryopreserve cattle and buffalo semen. Foetal calf serum
(10.00%), caffeine (1.00mM), insulin (10.00µg/ml) and ascorbic acid
(45.00µM) singly and/or in various combinations
were found suitable additives to EYT for cryopreservation of
bovine and bubaline semen.
iii.
The antioxidant n-propyl gallate (15.00µM), stimulants-caffeine
(1.00mM) and Bradykinin (2.00ng/ ml) and membrane stabilizer Demecolcin
(0.50µg/ml) had significant beneficial effect on buffalo semen cryopreservation
and had better in-vitro fertility. Use of buffalo semen frozen in modified dilutor (Tris
+ 15.00µM n-propyl gallate + 1.00mM caffeine + 0.50 µg/ ml Demecolcin) under field
conditions, revealed 52.00% conception (n=75) compared to 45.00% conception (n=119)
using control (Tris) dilutor.
iv.
During investigation into bacterial load of semen and suitable
antibiotic, it was concluded that streptomycin (800.00µg per ml) and
penicillin (800.00 IU per ml) was the minimum effective dose to reduce
the bacterial load to permissible level in frozen semen of cattle and
buffalo. Minimum and maximum dose of amikacin for bovine frozen semen
was 100.00 and 2500.00 µg/ml. Corresponding values for buffalo were
250.00 and 2000.00 µg/ml. December witnessed minimum bacterial load in
cattle and buffalo semen ejaculate, while maximum one was in August.
v. FMD vaccination of cattle and buffalo bulls, adversely affected the
semen quality, which returned to normal in 60-75 days.
3. Fertility-infertility
i.
While studying different aspects of female fertility, it was found
that proteins and sialic acid in estrual mucus of Crossbred and
Sahiwal cows and Murrah buffaloes were higher in normal animals than
in repeat breeders and they were responsible for higher conception
rate. However, progesterone level differed non-significantly between
normal and repeat breeding animals.
ii. Incidence of retained placenta was the highest in cattle during winter
followed by metritis and dystokia. However, metritis was witnessed
maximum in buffaloes followed by RP, dystokia and vaginal prolapse.
Overall incidences of reproductive disorders were maximum (45-89.00%)
in rainy season. Studies on caesarotomy in dystokia cases revealed
that most of operated cows and buffaloes attained normal health status
in 168 hrs.
iii.
Emetic nuts were found significantly (P<0.01) effective remedy to
treat anestrus, as 88.80% of the treated cows exhibited estrus as
compared to only 15.00% in control.
iv.
Different drugs were tested to select suitable therapeutic package to
treat anestrum in buffaloes. The overall recovery rate with Receptal
treatment was 85.71% at Livestock Research Center of the University
and 50.00% in field buffaloes compared to 0.00 and 12.50% recovery in
control groups, respectively. The overall recovery with Crestar
treatment on anoestrous buffaloes was 62.50% in L.R.C. buffaloes and
87.50% in field buffaloes compared to 2.50% recovery in control groups
both in L.R.C. and field buffaloes. The anoestrous recovery in field
buffaloes ranged from 75.00% to 87.50% with CIDR treatment. The CIDR
treatment was found to be the most suitable.
