Abstract/ Executive Summary:

An investigation was made was conducted at Bangladesh Agricultural University Dairy Farm for a period of six months. A total of 164 dairy cows belongs to different breeds, such as Jersey cross, Sahiwal cross, Sindhi cross, Holstein cross and Red Chittagong cows were selected and their information regarding milk production and other reproductive parameters were collected from farm records for a period of last five years (1993-1997). The number of animals of each of the genotypie classes were 48 for Jersey cross, 46 for Sahiwal cross, 35 for Sindhi cross, 20 for Holstein cross and 15 for Red-Chittagong. Significant difference was found within the milk yield (p 0.05). Highest milk yield (3.20 l/day), highest birth weight of calves (15.2 kg) and lowest calving interval (414 days) were observed for Holstein cross. The lowest milk yield (2.46 lit/day) and lowest birth weight of calves were found in case of Red-Chittagong cows. Production performance of Holstein crossbred were superior to other dairy crossbreds. Jersey crossbred ranked second and performances of the rest genotypes were nearly similar.

Keywords: Productive, Reproductive, Milk yield, Crossbred dairy cows

Location: Bangladesh Agricultural University Dairy Farm

Start Date: 00-07-1997

End Date: 00-12-1997

Program Area: Variety and Species

Commodity: Cow

Objectives:

i) To know the productive and reproductive performance of different dairy breeds and crossbreds of Bangladesh Agricultural University Dairy Farm.

ii) To recommend farmers about the breed and type of animals and profitable rearing and management practice

Methodology:

The t experiment was conducted at the Bangladesh Agricultural University Dairy Farm for a period of six months from July- December' 1997.A total of 164 dairy cows belonging to different breeds, such as Jersey cross, Sahiwal cross, Sindhi cross, Holstein cross and Red Chittagong cows were selected and their information regarding milk production and other reproductive parameters were collected from farm records for a period of last five years (1993-1997). The number of animals of each of the genotypic classes were 48 for Jersey cross, 46 for Sahiwal cross, 35 for Sindhi cross, 20 for Holstein cross and 15 for Red-Chittagong. The animals, which have at least five lactation periods, were only used for this study. Similarly, birth weights of 94 cleaves from different genotypes were collected to monitor the effect of breeds on birth weight oc calves. Stall feeding was the main feature of feeding, although very limited grazing was also done. Milk yield, lactation lenght, gestation length, service per conception, calving interval, birth weight of calves were used to measure the productive and reproductive performance of different genotypes. Analysis of variance test was performed to find the statistical difference between the productive and reproductive traits of different breeds. SED values were also calculated to find the significant differences within the different treatment means.

Achievement/Findings:

It might be concluded that, production performance of Holstein crossbred was superior than other dairy crossbreds. Jersey crossbred ranked second and performances of other breeds were nearly similar. Data on production and reproduction indicated that, the milk production of crossbred cows were higher than that of Red-Chittagong cows .Although our native Red-Chittagong cows produced little less milk than crossbreds, but since it had adjusted with our climatic condition, and since it is easier than that of crossbred cows in respect of management; thus can't be ignored.
