Effect of feeding of Morinda citrifolia fruit juice on the biophysical parameters of healthy as well as mastitis-affected cow milk

摘要

The present study was conducted to assess the effect of Morinda citrifolia fruit juice on milk characteristics of healthy as well as mastitis-affected dairy cow. A total of 25 adult dairy cows were selected out of which 13 were healthy and 12 were found affected with sub-clinical mastitis. M. citrifolia fruit juice was fed to dairy cow at the rate of 100 ml/day/animal orally. The average pH of the normal milk and mastitis-affected milk was 6.60???±0.12 and 7.2???±0.17, respectively. The feeding of M. citrifolia juice significantly ( p <0.05) lowered the pH of mastitis-affected milk to 6.54???±0.07. The EC of mastitis-affected milk lowered significantly ( p <0.05) after feeding of M. citrifolia fruit juice. The total bacterial count in the mastitis milk also decreased significantly ( p <0.05) from 5.15???±0.03????10 8 to 2.54???±0.03????10 8 cfu/ml after feeding of M. citrifolia juice. Morinda feeding decreased the total protein concentration in the mastitis milk significantly ( p <0.05) to 21.13???±0.93 ???μg/ml. It could be concluded that the feeding of M. citrifolia fruit juice to dairy cows showed improvement in the quality and biophysical parameters of milk of mastitis-infected dairy animals.
