Abstract
A total of 90 lactating cows from twelve dairy farms were used to conduct this study in order to evaluate the productive and reproductive performance of crossbred and local cows at farmer’s level in Manikgong district. All cows were divided into three groups, according to their genetic composition as Local, Local x Friesian and Local x Friesian x Friesian cows. The results showed late sexual maturity (37.41±0.03 months), calving interval (481.86±0.33 days), shortest lactation period (198.46±2.36 days) and lowest average milk production (2.25±0.04 L/day) in local cows. On the contrary, longest lactation period (266.43±1.18 days) and highest average milk production (7.45±0.11 L/day) were observed in LFF cows, whereas early sexual maturity (30.58±0.02 months) was found in Local x Friesian cows. From the above perspective it could be concluded that LFF crossbred cows may be suitable for profitable dairy farming in Bangladesh but herd life and life time productivity is one of the most influential factor for profitable dairy farming. However, further study with larger sample sizes covering more different management systems would be required to describe a better inference in this consideration.Asian J. Med. Biol. Res.

Highlights
Livestock is the prominent sector of agriculture and the contribution of this sector in GDP is 3.49% (BER, 2016) and in agricultural GDP is about 14.21% (DLS, 2016)
Cows were divided into three genetic groups according to their genetic composition, such as local cows (L, n=30), Local x Friesian (LF, n=30) and Local x Friesian x Friesian (LFF, n=30)
Results on productive and reproductive performances of local and crossbred cows were summarized in Tables 1 and 2
Summary
Livestock is the prominent sector of agriculture and the contribution of this sector in GDP is 3.49% (BER, 2016) and in agricultural GDP is about 14.21% (DLS, 2016). Age at puberty, service per conception, gestation length and birth weight of fetus are most important parameters to measure the farm economy. A farm with 13-15 months calving interval, 24 months for age at puberty, 1.33 services per conception and 5 kg milk per day per cow could be economically profitable (Azizunnesa, 2010).
