Abstract
ABSTRACT:
Treatment of true anoestrous and subestrus high yielding lactating graded
Murrah buffaloes (Bubalus bubalis) using estrus and ovulation hormonal protocols,
Ovsynch (Group A), Double PGF2α (Group B) and their influence on fertility during low
breeding season was studied. The estrus detection rate was 77.77 (14/18), and
93.33(28/30) per cent in Ovsynch (true anoestrous) and Double PGF2α (subestrus)
groups. There was no significant difference in mean time to onset of estrus between the
treatments. Most buffaloes in the present study showed intermediate to weak estrus signs
in Ovsynch (Group A) group on the contrary, the double PG showed intense to
intermediate estrus in more (27/28) number of animals. Peak estrus synchrony with highest number of animals exhibited estrus between 48 to 72h with 9/14 in group A and 20/28 in group B. The artificial submission rate was 77.77(14/18) and 93.33 (28/30) per cent in Ovsynch and Double PGF2α, respectively. Ovulation rate of 85.71 (12/14), 89.28(25/28), per cent was observed in Ovsynch (Group A) and Double PG (Group B), respectively.
The conception rate at induced estrus with Ovsynch in the treatment of true anoestrous buffaloes, and Double PG in the treatment of subestrus buffaloes were 64.28
(9/14), and 75.00 (21/28) percent, respectively with an overall conception rate of 77.77
(14/18), and 86.66 (26/30) per cent. During this treatment period in the control group,
only 50.00 (5/10) and 50.00 (5/10) per cent anoestrous buffaloes exhibited estrus and
conceived, respectively. The mean level of Hemoglobin, PCV is statistically significant on the day 0 and on the day of induced estrus at (P<0.05). The total serum cholesterol, Glucose and protein profile were non-significantly different (P>0.05) between conceived and nonconceived buffaloes, in both the treatments. The mineral profile did not reveal
significant variations (P>0.05) in serum calcium, phosphorus concentrations of buffaloes
between days/periods of the treatments with Ovsynch and double PG protocols.
The results of present study, with inseminations at observed estrus appears as an
effective way of managing reproduction true anoestrous (acyclic) buffaloes with
Ovsynch and subestrus buffaloes with luteal activity using double injection
prostaglandins as we could record acceptable ovulation and conception rates.
