Abstract
Aim:
Anoestrus is one of the most common functional disorders of
the reproductive cycle in buffaloes. In spite of technical
advancement, there is no single cure for the management of
anoestrus. Therefore, the aim of this study was to find out the
efficacy of gonadotropic releasing hormone (GnRH) and metabolic
hormone for the management of true anoestrus in buffaloes.
Materials and Methods: The experimental animals were selected
on the basis of history, gyneco-clinical examinations and
progesterone estimation. Deworming was done with Fenbendazole and
thereafter mineral mixture was given @ 50 g per animal per day for
10 days in all the selected buffaloes before the start of
treatment. The selected buffaloes were randomly divided into four
groups (n=25). In Group I, buffaloes were administered 20 μg of
buserelin intramuscularly. Buffaloes of Group II were administered
long-acting insulin @ 0.25 IU/Kg body weight subcutaneously for 5
consecutive days. In Group III, buffaloes were treated with a
combination of insulin and buserelin in the above-mentioned doses
whereas buffaloes of Group IV were kept as untreated control.
Results: The higher oestrus induction (64%
vs. 28%) was found in Group III and differed significantly
(p<0.05) as compared to control group. The conception rate (69.23%
vs. 66.66%) was also found higher in Group III but did not differ
significantly among the treated groups. The mean time taken for
the onset of oestrus was recorded significantly shorter in insulin
(8.80±0.69) and GnRH (7.60±0.92 days) alone and as compared to
other (Group III, 14.43±0.83 and Group IV, 20.57±1.69 days)
groups.
Conclusion: The results of this study
indicated better fertility response using Insulin plus Buserelin
in true anoestrus buffaloes under field conditions.
Keywords: anoestrus, buffalo, buserelin,
gonadotropic releasing hormone, insulin.
