| description |
During the last years bufalo reproductive
researchers have been tried to develop and apply
fxed timed artifcial insemination protocols
to increase pregnancy rates to maximize
improvement. The objective of this paper is to
evaluate the pregnancy rates of diferent protocols
of synchronization (Ovsynch and progesterone
implants) and resynchronization of ovulation in a
meat water bufalo herd during reproductive season
of 2016. 194 mature Mediterranean females, were
randomly assigned to four diferent protocols,
ultrasound evaluation were used to determine
cyclicity (presence of corpus luteum or follicles
≥7 mm de diameter). 18 days after insemination
all females were resynchronized and at day 25
ultrasound were performed, those nonpregnant
females were inseminated 28 days after frst
insemination. All inseminations were performed
by the same technician and only one bull was used.
InfoStat software was used, statistical signifcance
was considered when p value was lower than α
of the 5%. No statistical signifcance were found
within the protocols. Early embryonic dead 50
days after IA was 3.4%. Pregnancy rate was 47.9%
and 53.5% for insemination and reinsemination
respectively and the fnal pregnancy rate after the
adjust for early pregnancy loss 73.2%, during the
28 days of the breeding period. The results obtained
allow breeders to choose the best pharmacological
option to use FTAI in their herds based on their
own needs to improve production without afecting
pregnancy rates. |
