title: Effects of treatment for anestrus in water buffaloes with PGF2α and GnRH in comparison with vitamin-mineral supplement, and some factors influencing treatment effects.
abstract: The effect of treatment for anestrus in buffaloes with a PGF2α or GnRH injection and vitamin-mineral (Vit-M) supplementation for 1 to 2 months and some factors influencing the treatment effect were studied. In anestrus buffaloes with CL, an injection of PGF2α tended to show higher estrus detection and pregnancy rates within 17 days after treatment than Vit-M supplementation (P<0.10). In those with inactive ovaries, effect of GnRH and Vit-M did not differ. Body condition score of the animals before treatment affected pregnancy rate within 17 days after treatment (P<0.05). Pregnancy rate within 4 months after treatment was adversely influenced by low serum concentrations of calcium (P<0.01) and gastrointestinal parasitic infection before treatment (P<0.05).
