Abstract
The present study was undertaken from January to June, 2014 to investigate the morphometric, productive and reproductive characteristics of Dwarf cattle available in Dinajpur District. The data obtained from 200 Dwarf cattle of different categories (yearling bull, adult bull, heifer, cow, male calf and female calf). A wide variety of coat colors among the cattle of the selected areas were found. The head length and width, ear length and width, horn length and diameter, neck length and width, body length at shoulder, wither height, heart girth, fore leg and hind leg length, tail length and diameter, teat length and diameter, distance between fore teats and rear teats, length and width of testis, weight of testis, live weight, daily milk yield, lactation length, gestation length, calving interval, dry period, post partum heat period, age at first heat and service per conception were recorded. The Dwarf cattle in Dinajpur District are comparatively smaller in size than most of the recognized breeds or types of cattle, however coat color showed remarkable variation. The data generated for Dwarf cattle in Dinajpur District would be useful to characterize them.Asian J. Med. Biol. Res. December 2015, 1(3): 380-386

Livestock is one of the major components of agricultural output of Bangladesh which plays a vital role in national economy
About 36% of the total animal protein comes from the livestock products in our everyday life and 25% people are directly engaged in livestock sector, and 50% peoples are partly associated with livestock production (DLS, 2014)
The present study was undertaken with the following objectives: a) To identify and characterize the Dwarf cattle reared in Dinajpur District of Bangladesh. b) To assess their productive and reproductive performances and comparing with other cattle available in
Summary
Livestock is one of the major components of agricultural output of Bangladesh which plays a vital role in national economy. In spite of a high density of livestock population, the country suffers from an acute shortage of livestock products like milk, meat and eggs. Soil type and availability of fodder, different varieties of cattle genetic resources are available in different parts of the country like non-descriptive Local Red Chittagong, Pabna, North Bengal Grey, Madaripur, Hilly and Munshigong (Bhuiyan et al, 2005). Another type of cattle is called Dwarf cattle found in Northern areas of Bangladesh which is very short in size and can produce milk almost throughout the year without sufficient grazing. The present study was undertaken with the following objectives: a) To identify and characterize the Dwarf cattle reared in Dinajpur District of Bangladesh. b) To assess their productive and reproductive performances and comparing with other cattle available in Bangladesh
