Study on production performance, feeding management and diseases occurrence of cross-bred cows under rural condition at Shalikha upazila of Magura

Abstract

The study was carried out to monitor the comparative milk production performance of cross-bred cows under rural environment in different parities. The data of 40 cross-bred lactating cows of five different parities were collected. The collected data shows that average daily milk yield and lactation yield of cross-bred lactating cows are 7.7 liter per cow per day and 1769.5 liter per cow per lactation .The result shows that average daily milk yields are higher in forth parity (10 liter) where average lengths of lactation are also high (250 days). It appears that third and fourth parities cross-bred were more suitable for milk production among the other parities studied. Some diseases hamper the milk production of dairy cows such as mastitis, skin diseases, and parasitic diseases. This study shows that mastitis occurrence rate (15%) is higher than other diseases like skin diseases (7.5%), parasitic diseases (5%). To control this diseases proper vaccination, deworming should be compulsory. Balance rations is the important factor for milk production. This study shows the rural farmers provide Straw 3Kg/day, roughage 4.5 kg/day and concentrate 1kg/day .There is no supplement of separate protein. To get proper production balanced ration is very essential.
