The Effects of Concentrated Feed Level on the Milk Production and Composition

In this research, The effects of concentrated feed level on dry matter consumption of dairy cows, milk composition and some blood parametres were investigated. At the end of the experiment, it was found that increasing the level of concentrated feed (From 0.4 kg day-1 to 0.5 kg day-1 per kg milk) did not increase the milk production. However, this increase in concentrated feed level leaded to an increase in the level of milk protein (P < 0.01).
