Abstract
Aim: Postpartum anestrus is
one of the major problems in buffalo reproduction; the knowledge
of its incidence may be helpful to adopt preventive and
therapeutic measures for improvement of reproductive efficiency
and thus production of the dairy animals.
Materials and Methods: To investigate the incidence of
postpartum anestrus, a total 6105 Murrah and upgraded Murrah
buffaloes were surveyed in and around the district of Jabalpur,
Madhya Pradesh, India. Among these, 4708 and 1397 buffaloes were
surveyed in organized and unorganized rearing system,
respectively. Among the organized farms, 2050 and 2658 buffaloes
were observed in good and moderate managemental condition,
respectively. Anestrus and sub estrus were confirmed by per rectal
examination and serum progesterone estimation.
Results: The overall incidence of anestrus was recorded
29.12%. The incidence of anestrus was recorded 25.84% and 40.15 %,
respectively, in organized and unorganized rearing system, and
among organized farms it was 22.58% and 28.36% in good and
moderate managemental conditions, respectively. The incidence of
anestrus in summer, rainy, and winter season was found to be
66.28%, 22.51%, and 11.25%, respectively. Based on per-rectal
examination and serum progesterone concentration, 60.58 per cent
buffaloes were classified as true anestrus, 20.88 per cent as sub
estrus, and 18.52 per cent anestrus due to other unknown
conditions.
Conclusion: These results indicated that the incidence of
anestrus, especially true anestrus, was higher at farmer's door.
Moreover, the incidence of anestrus was higher in summer season
and hence appropriate preventive and or therapeutic measures as
per the type of anestrus need to be undertaken.
