A Cross-Sectional Study on Production Performance of Stall Fed Dairy Cattle at Central Cattle Breeding Station (CCBS), Savar, Dhaka

Abstract
To evaluate milk production performance in stall feeding dairy cattle in relation to associated biological factors such as age of cow, age of first calving, breed and number of parity at Central Cattle Breeding Station, Savar, Dhaka, a cross sectional study was performed on April, 2002 using a structured questionnaire. Local (21%), pure bred "Sahiwal" (12%) and cross bred (L×F1; L×F2; L×F3; SL×F2>) (67%) were the breed of studied cows (n = 62). The average age and milk production of the cow was 94.9 months and 3.9 liter/cow/day. The parity number and age at first calving of a cow were recorded to be average 4 and 43 months respectively. The younger cows (≤99 months) were 6.7 time more likely to have yielded >3 liters/cow/day than the older cows (>99 months) (p < 0.001). Cows with ≤4 parities were recorded to have 7.6 times more chance to produce milk of >3 liters/cow/day than cows with ≥4 parities (10.9%) (p < 0.001)). The milk production of >3 liters/cow/day is 39.3 times higher in the crossbred than the milk production in the local breed (p < 0.001).
