We were feeding corn silage to our dairy cows. Once we ran out of corn silage, we shifted to feeding whole fine chopped sugarcane without tops to our cows. The cows are eating the same level of concentrates but overall milk yield is continuously declining. The cattle seems to like the sugarcane a lot and eat upto 16-20 kg as-fed per day (30% dry matter). Do we need to add any supplements in sugarcane to balance the ration. Any inputs on this would be very helpful.
