Effect of Seasonal Conditions on Oestrus Occurrence and Postpartum Period in Anatolian Water Buffaloes. Deutsche Tierarztliche Wochenschrift, 109(9), 416-418.0341-6593https://hdl.handle.net/20.500.12395/17929Oestrus and calving records of Anatolian buffaloes were analyzed to investigate influence of climatic conditions on oestrus occurrence and postpartum period. Oestrus records showed a seasonal pattern concentrated between July and September which is the warmest period of the year. Likewise, more than half (52.7%) of the total calvings occurred between May and August. Month of calving significantly influenced the length of calving to first oestrus interval and open period (P < 0.01). The average length of open period was significantly shorter in autumn and summer calvers compared to those calved in spring and winter (P < 0.05) during long days. The humidity rate was negatively correlated with both calving to first oestrus interval and open period (P < 0.05). In conclusion, exposure to high environmental temperatures around 20 degreesC exerted no suppressive influence on ovarian activity in Anatolian buffaloes. Although humidity rate (P < 0.05) and ambient temperature (P < 0.01) was found to be correlated with the duration of postpartum period, day length might be the main factor regulating reproductive biorhythm and postpartum events in Anatolian buffalo cows.eninfo:eu-repo/semantics/closedAccessbuffaloclimateoestruspostpartum periodArticle109941641812395581N/AWOS:000178358200006Q2
