Bangladesh largely depends on agriculture. Livestock being one of the e
components of agriculture (crops, livestock, fisheries and forestry) plays
vital role in national economy, contributing about 6.7% of gross domestic
products (GDP) and 13% of total foreign exchange earnings (BSS, 2010)
Livestock rearing is an integral part in the mixed farming system 0. Bangladesh. According to Food and Agricultural Organization the cattle population is about 24.5 million cattle and Milking cows account for abou. 45% of the total cattle population (FAO, 2004). The milk yield of cows ix very low in Bangladesh, although the yield is increasing through crossbreeding. The current annul milk production is around 2.5 million tones, o! which 98 per cent comes from cows. The annual demand is around 12.5 million tones (DLS, 2010). Average milk production of the local cows is one liter per head and total milk production is 1.57 million metric ton; demand per capita is 240g, whereas availability is only 37g per capita per day (Anon, 1997). This amount of milk is only 20% of the total milk requirement. Thus it is necessary to increase the milk production. Modern technologies, if properly generated through research and adopted in respect of breeding, feeding, management and disease control can raise the production to a much higher extent. F ortunately, Bangladesh Government
has presently given the top priority in milk production. | en_US |
| dc.description.abstract | An observational epidemiologic study was conducted on 472 dairy cows
indigenous 110 and its crosses 362, of 180 Government registered dairy farm in
Rangpur milk shed area during September 2010 to August 201 to study
association of cow, udder and teat characteristics with udder and teat diseases,
milk yield and milk flow rate. Mastitis (28.18%) was most common disease
followed by udder skin diseases (16.10%) and teat diseases (13.98%). Prevalence
of injuries and other lesions was higher in the skin of fore left udder quarter
(22.67% and teat (22.6%) and rear left teat end (6.14%). Mastitis was found to
be associated with indigenous and Sahiwal cross cow, poor body condition,
bottle shaped teat, teat with round end, injuries and other lesions to the other and
teat skin and teat diseases. Udder skin diseases were strongly associated with
indigenous cows, cow aged 5- 10 years, small milk vein, larger front udder,
bottle shaped teats and flat end teats. Milk flow rate was higher in indigenous
and Jersey crosses, poor condition, large milk vein, larger front udder, funnel
and cylindrical teats and pointed teat ends. Risk factors of udder and teat
diseases, milk yield and milk flow rate in high yielding indigenous and its cross
cows are not similar to those of exotic cows and their crosses. | en_US |
