The present study investigated the occurrence of repeat breeding (RB) and constraints in controlling this disease in cattle and buffalo in Punjab. Livestock owners/households (720) constituted the ultimate sampling units for the study. The dairy farmers were categorized into small (5–10 animals), medium (11–50) and large (>50) farmers. The overall prevalence of repeat breeding in the study area was 27.6%. It varied significantly with respect to herd size and categories of animals except in buffaloes. The highest prevalence was observed in crossbred cattle (41.8%), followed by indigenous cattle (32.0%) and buffaloes (17.6%). Repeat breeder animals were mostly high yielders (with >15 kg milk yield), calved mostly in winter season, having below average body condition score (BCS). No significant correlation was observed between parity (lactation number) and type of calving and prevalence of repeat breeding. The major constraint (rank I) perceived by farmers was culling of affected problematic cows, and lack of effective and accurate estrus detection in buffaloes. The other major constraints perceived in the study area were high cost of veterinary medicine, poor conception rate following artificial insemination and inaccessibility of qualified veterinarian. The lack of knowledge regarding animal nutrition and higher cost of branded feed available in the market were responsible for low body condition score of affected animals. Thus, a comprehensive policy and programmes involving various stakeholders are required for effective control of repeat breeding in Punjab.
