The present study was undertaken to estimate the performance of some reproductive traits of Red Chittagong Cattle (RCC) is an important indigenous Farm Animal Genetic Resource of Bangladesh having some efficient reproductive capabilities. The effect of parity on these traits was also studied. The study was conducted in the nucleus herd of RCC Project at Bangladesh Agricultural University (BAU) dairy farm taking data from 2005 to 2008. The traits considered for this study were age at sexual maturity, age at first calving, number of service per conception, conception rate, calving interval, post partum heat period, gestation length and service period of RCC cows. The mean (±SE) values of the said traits are 28.75 ± 1.26 months, 40.93 ± 1.74 months, 1.55 ± 0.08, 78.91 ± 2.82 %, 14.42 ± 0.33 months, 127.71 ± 7.02 days, 282.11 ± 0.58 days and 151.72 ± 6.83 days, respectively. All the traits studied did not differ significantly (P>0.05) between different parities.
