A retrospective-epidemiological study of cattle diseases/disorders was conducted at Baghabari Milking zone of Bangladesh starting from June 2008 to May 2012. Out of 22066 cases, 73.95% and 17.16% diseases/disorders were recorded in cows and calves respectively. About 58.42%, 23.56% 12.48% and 5.54% cases were general and systemic, infectious, production and reproductive and surgical diseases/disorders respectively. The most common general and systemic diseases/disorders were fever (17.91%), anorexia (17.55%) and weakness (14.71%). Among infectious diseases, 78.2%, 7.02% and 6.32% respectively were mastitis, FMD and black quarter. The predominant production and reproductive diseases were milk fever (33.48%), repeat breeder (17.10%), retained placenta (14.27%), metritis (13.11) and anestrous (11.44%). The most common surgical disorders were navel ill (46.9%), wound (20.19%), abscess (8.99%) and urolithiasis (8.67%). Statistically significant variation of diseases in different seasons was also noted. We recommend for undertaking research focusing on the causes of fever, anorexia and weakness as they were the most predominant general and systemic disorders of cattle. Control measure should be initiated to reduce the burden of mastitis, repeat breeder, retained placenta and anestrous which were most common production and reproductive diseases in the study area. A case control study may help to reveal the factors responsible for such a high level of occurrence of navel ill in calves. This study generated information which is valuable not only for the clinicians, researchers, animal health companies and policy planners but also for the academicians to update veterinary curricula.

The result of the collected data revealed different reproductive performances of RedChittagong Cow such as age at puberty 2.68±1.72 years, days required to first heat during postpartum period 3.08±1.00 months, calving interval 14.00±1.19 months, service per conception1.36±0.60 and gestation length 279.92±5.27 days. In this survey some data were recorded toobserve the production performances of Red Chittagong Cows. Milk production per day andlactation length was 2.10±0.63 liter and 238.8±30.6 days, respectively. The maximum milkproduction per day was 4 liter per cow and the minimum production was 1 liter per day per cow.The cow produced 1.88±0.51 liter milk supplied with roughage only on the other hand 2.42±0.57liter milk produced by the cow supplied some amount of concentrate along with roughage. Thelevel of production difference between two groups were highly significant (p<0.0001).Key Words: Lactation; Puberty; Service per conception; RCC.DOI: 10.3329/ujzru.v28i0.5282Univ. j. zool.
