Effect of ultrasonography on the efficacy of fish in treatment of anoestrus buffaloes [electronic resource].

Includes references.

Buffaloes are apparently of low ovarian response, repeat breeders and silent heat due to the weak estrous symptoms. Different hormonal treatments failed to give a high percentage of success due to the diagnosis accuracy for the ovarian response. The present studV was conducted on 50 anoestrus buffalo-cows. 5-7 years old, divided into 2 groups (A and B). Group A included 25 buffalo-cows, their ovaries showed small-sized antral follicles based on Ultrasonographic examination. Group B included 25 buffalo -cows randomlv selected based on rectal examination that revealed structureless ovaries. Animals in both groups were injected witll an activating dose of FSH-P (4IU/animal) and if the animal does not respond. a second dose (4 IU) was injected af- ter 2 weeks from the first one. All animals were examined rectally and sonographically twice weekly after treatment.
