The use of urea by lactating dairy cows when fed maize silage

  • 1986
  • Issue: 2
  • Volume: 16
T.J. Dugmore, R.M. Bredon & K.P. Walsh Page: 87 - 89

    Maize silage is relatively high in energy but low in protein for the normal lactational requirements of dairy cows. Three trials were conducted to compare the use of urea as opposed to natural protein supplements in balancing the…
