Abstract: Study was conducted to determine the occurrence of repeat breeding and prolonged oestrus among crossbred cattle in organized farms. Data were collected from breeding registers maintained on farms over a period of four years and tabulated in relation to age and parity. Overall occurrence of repeat breeding, prolonged oestrus and occurrence of prolonged oestrus among repeat breeder animals was 25.96 per cent, 25.86 per cent and 55.42 per cent, respectively. Occurrence of repeat breeding, prolonged oestrus and repeat breeding among prolonged oestrus exhibiting animals among cows was 27.35, 30.29, and 61.58 per cent, respectively. Occurrence of repeat breeding, prolonged oestrus and repeat breeding among animals exhibiting prolonged oestrus, among heifers was 23.07, 16.66, and 40.27 per cent, respectively. Among cows, the occurrence of repeat breeding was highest in the age group of 2-4 years and occurrence of prolonged oestrus among repeat breeders was highest in the age group 8-12 years.
