Abstract: The cross sectional study was performed to find out different production parameter and their association with certain diseases of dairy cattle at Savar dairy farm.One year’s data (from 1st January to 31st December 2019) was collected from the register book and recent data collected from face to face questionnaire with the employee and veterinary surgeon. Among selected five sheds,the daily average milk yield, roughage and concentrate intake was 670 litre,934.4 kg and 475.4 kg respectively. Among 25 cows (five cows from each shed) 96% cows were cross breed and 4% cows were local breed,52% cows were at the below or age of 6.4 years, most of the cow’s body weight 351 to500 kg, good BCS, 11 liter or below 11 litre per day,in first parity and late lactation. Acidosis was the most commonly(72%) occurred disease where lameness (16%) was least common. The highest used antibiotics was Gentamycin (36.4%) and the combination of amoxicillin and cloxacillin(36.4%) and the least was Renamycine (1%).Significant relation present between body weight with milk yield and roughage intake with milk yield. Body weight, number of parity and roughage intake have positive correlation with the milk yield. Mastitis and BCS have negative correlation with the milk yield .Cows in second lactation with 12- 14 litre milk yield have the highest risk of mastitis. Cow who intake 21.1 to 30 kg roughages with 9 to 14 milk yield have the more risk of occurring mastitis than the cows who intake 21 or less roughages with 7 to 12 litre milk yield The frequency of mastitis is highest in 3rd parity with 12 to 16 liter milk yield. From this study the overall productive performance and commonly occurring disease and their associated risk factors were identified which is helpful for better management and improved production of dairy cows.
