dc.description.abstractThe experiment was done to monitor the comparative study on productive and reproductive performance of different dairy cows under farm condition. For achieving this goal 100 dairy cows were selected from different place of Chittagong metropolitan area. The data collected from different place such as Bayezid, Nazumiar hat, Baklia, Potenga, Baluchora etc. The productive and reproductive parameters of 100 cows of different breeds such as Local non descriptive, Local x Shahiwal, Local x Holstein Friesian, Holstein Friesian x Shahiwal were investigated and evaluated for productive and reproductive performance. The study found that the productive parameters of Holstein Friesian x Shahiwal cross breed showed the highest average milk production (15.184±0.418 L) whereas the lowest average milk production found in local breed (2.548±0.121 L). Besides, Holstein Friesian x Shahiwal showed the highest average lactation length (324.76±2.645 days) and local breed showed the lowest average lactation length (205.16±2.194). In case of reproductive parameters, the Local x Holstein Friesian cross breed showed the lowest average age of puberty (24.92±1.186 months) whereas Local x Shahiwal showed the higher age of puberty (29.6±1.099 months. The average gestation period of Holstein Friesian x Shahiwal cross breed found (280.92±0.785 days) which is almost similar to the other cross breed and local breed. The Holstein Friesian x Shahiwal cross breed showed the lowest average intercalving period (16.64±0.443 months) than the lowest average intercalving period observed in Local x Shahiwal cross breed (21.6±0.516 months). Considering all the parameters studied, Holstein Friesian x Shahiwal crosses productive and reproductive performances are superior to other crosses. At present study it may be concluded that Friesian x Shahiwal crosses show better performance followed by local non descriptive, Local x Shahiwal, Local x Holstein Friesian.en_US
