BRIEF COMMUNICATION: Feed value of maize silage in New Zealand - a review

摘要

Maize silage is a major dietary component for dairy cows in the USA and Germany with average feeding rates of 2.7 and 4.1 tDM per cow per year respectively (Table 1).Maize silage usage in NZ has increased over the past two decades. It currently accounts for approximately 6% of feed energy supplied to the national herd, calculated using national herd energy requirements (based on cow numbers and milk processed 2013/14 in NZ (New Zealand Dairy Statistics 2013/14)) and the amount of maize silage harvested (AIMI2015).
