Reproductive
Biology Research Unit
Collge of Veternary SCI. & A. H.
Anand Agricultural University,
Anand-388110
Year of Establishment
1958.
Introduction
The
unit is working on different aspects of Reproductive Biology of farm
animals viz., Surti buffalo and Surti and Marwari goats of Gujarat
state; with special emphases on endocrinological aspects during
different phases of reproduction. Study on augmentation of reproductive
efficiency through management, hormonal therapy and other related
aspects were taken up. Embryo transfer work of cattle, buffalo and
goats have also been taken up. These all works are taken up as per the
technical programme of various plan, non-plan and Adhoc schemes of GAU/AAU,
ICAR, PL-480 (USA), Ford foundation, BARC-DAE etc.

Research
Activities
Crop improvement
Research work in relation to hormonal status of buffaloes
and goats in relation to reproductive phases, abnormalities
of reproduction such as sub estrus , anestrus , EEM ,
persistant corpus luteum etc. is given main emphases.Factors
controlling and affecting superovulation, embryo recovery,
quality of embryo, pregnancy establishment in recipient etc.
are studied in buffaloes and goats.
Managemental and endocrine aspects to improve reproductive
ffficiency in buffaloes and goats to improve production
efficiency are also continue in study
Research Recommendations Made
for the Farmer (Approved by Joint AGRESCO)
Surti buffalo heifers can be made pregnant at the
age of 15-16 months by following management/ care
and feeding practices.
:-
Colostrums should be fed within 15-30min.of birth
:-
After birth up to 3 days, 1.5 to 2.0 lit. colostrums
should be fed in 4 to 5 feeding. After feeding clean
the mouth to prevent infection.
:-
Give mothers milk up to 20-25days and allow/ light
exercise for 30to40min.after feeding.
:-
After one month of birth, heifers (female
calf),should allow to lick the brick and fed
100-150gm.dan (concentrate) and fodder and give
drinking water ad-lib.
:-
After one year of age, heifers should be let loose
in open yard/paddock daily in morning and evening to
monitor the estrus symptoms. Carry out AI in such
estrus female timely , so that heifers can be made
pregnant at an early age of 15-16 months.
Calving interval can be maintain 13-14 months in
Surti buffaloes by allowing breeding management.
:-
After parturition buffalo comes always in heat
within 28-30days. When they come in second estrus
within 45-120 days, if breeding is carry out , there
are maximum chance to get conceived. This way
breeding can be helpful to manage calving interval
13-14 months.
Routinely farmers know their buffalo in estrus by
the signs viz., Bellowing, drop in milk yield ,
vaginal mucus discharge etc.. However these symptoms
are not fix/ reliable in each animal at every time .
Therefore to know the buffalo/heifers in estrus
frequent urination is the reliable sign of estrus .
Animal exhibit 5 to 7 times urination in small
quantity at 15 min. interval during 3-4 hrs. of
estrus.

:-
Factors
affecting to synchronization, superovulation and embryo
recovery are studied in details in cattle, buffalo and goats
with basic information of endocrinology associated with it.
Early pregnancy diagnosis (20 days post-breeding) in buffalo
and goats by estimation of serum and milk progesterone RIA
is standardize.
:-
Unit has
evolve a package of practices of successful weaning of
buffalo calf right at birth along with reducing calf
mortality, reducing age at first calving in heifers and
optimizing calving interval in dams. Package of practices
have also been evolved to avoid summer heat stress in
buffalo to improve breeding efficiency by timely and proper
heat detection and AI.
:-
Basic
endocrine data for different reproductive phases of Surti
buffaloes has been generated for different season of the
year.
:-
Department
is working as resource for RIA for estimating various
hormones from samples of various departments-schemes, P.G.

:-
Every year
more than 5000 visitors- farmers/farm women /students are
visiting unit and get the information regarding buffalo
management to improve reproductive efficiency and there by
productivity.
:-

has completed almost 12 research schemes of various plan,
non-plan and Adhoc -schemes of ICAR, PL-480 (USA), Ford
foundation, BARC-DAE, GAU/AAU, etc.
:-
Department
scientist has visited abroad to Netherlands, Egypt and
Malaysia.
:-
Department
has given training on RIA to foreign scientist from
Bangladesh.
:-
Department
has conducted National Seminar on Reproductive
Biology(1981), National Symposium and Conference-
ISSAR(1989), AICRP (buffalo) Workshop(1987),and Winter
school(2003) successfully.
:-
Fifty
pedigreed buffalo bull calves have been sold for breeding
purpose in the field to various agencies including AMUL,SAG
and BAIF.
:-
Almost 25
awards are received by the scientist of the unit at
national/state level.
:-
Unit has
published more than 250 research papers in national and
international journals.
Transfer of Technologies
: :
Managemental
practices evolved for successful weaning of buffalo calf
right at birth along with reducing calf mortality, reducing
age at first calving in heifers and optimizing calving
interval in dams are provided to the livestock owners by
extension activity. Package of practices evolved to avoid
summer heat stress in buffalo to improve breeding efficiency
by timely and proper heat detection and AI is also provided
to the farmers so that reproductive and productive
efficiency can be improved for their animals at field level.
: :
Establishment of non-surgical ETT in cattle and buffaloes
are standardize and scientist/ students are educated for the
same.
: :
Attempts are made to develop package of practices for
breeding of the goats through out the year, so that three
kid crops in two year times can be available to the farmers.
