<h3>Quick facts</h3>
<ul>
<li>Forty-nine percent of New Zealand's greenhouse gas emissions come from agriculture.</li>
<li>At the same time,&nbsp;more than 38%&nbsp;of New Zealand's merchandisable exports come from agriculture.&nbsp;</li>
<li>New Zealand is the number one contributor to the global dairy trade.</li>
</ul>
<h3>What's changed in the dairy sector since 1990 in on farm practices?</h3>
<ul>
<li>Consistent supply of high quality feed</li>
<li>Use of supplementary feed (e.g. maize silage, PKE, brassicas)</li>
<li>Targeted use of fertilisers and irrigation in pasture management strategies&nbsp;&nbsp;</li>
<li>Breeding and herd testing for animals with improved genetic merit</li>
</ul>
<h3>What's the impact of these on farm changes&nbsp;on productivity?</h3>
<ul>
<li>Increased milk yield per cow (kg MS/cow)</li>
<li>Increased milk&nbsp;yield per hectare (kg MS/ha)&nbsp;</li>
<li>Milk yield is closer to genetic potential of&nbsp;the cow</li>
</ul>
<h3>What's the effect of these changes on emissions intensity?&nbsp;</h3>
<p>Emissions intensity of New Zealand dairy sector is lower and a great proportion of feed goes to production rather than maintenance.</p>
