Within a generation, farmers have gone from receiving government funded incentives to increased stocking rates, cleared bush and scrub, and applied what we now know to be excessive amounts of fertiliser. They are now faced with the prospect of farming within limits imposed either naturally or by regulation.}, issn = {1176-5283}, author = {van Reenen EH} } @conference {3729, title = {Farming within limits; the new reality.

In relation to climate change, the key mechanism is the New Zealand Emissions Trading Scheme (ETS), which has been designed to put the New Zealand economy on a path to lower greenhouse gas (GHG) emissions and to respond to the country{\textquoteright}s international obligations. Although all developed countries that have ratified the Kyoto Protocol are responsible for their agricultural emissions, New Zealand is the only country in the world to include agriculture in an emissions trading scheme. With the inclusion of agriculture there are three key ways to incentivise a reduction in GHG emissions on-farm. These are through the point of obligation, the emission factor methodologies, and the allocation of "New Zealand Units" to the sector. Introducing agricultural GHG emissions into a New Zealand emissions trading scheme brings with it challenges and opportunities in a country that is heavily reliant on primary production for the health of the economy.}, issn = {1176-5283}, author = {van Reenen EH and Pickering AH} } @conference {42045, title = {Liveweight and body condition of single- and twin-bearing Merino ewes}, booktitle = {Proceedings of the New Zealand Society of Animal Production}, volume = {68}, year = {2008}, month = {Jan}, pages = {67-68}, publisher = {New Zealand Society of Animal Production}, organization = {New Zealand Society of Animal Production}, address = {Brisbane, Australia}, abstract = {

While dairy cows are generally milked twice-a-day (TAD) in New Zealand, more farmers are adopting a once-a-day (OAD) milking routine to improve their lifestyle, reduce farm costs and improve animal welfare. Clark et al. (2006) reported that the yield of milksolids (MS) from Jersey cows was less affected (-19.9\%/cow) by OAD milking than the MS yield from Holstein-Friesian cows (-29.4\%/cow). Jersey cows milked OAD in Taranaki between 2000 and 2004 averaged 222 kg MS/cow and 979 kg MS/ha (Clark et al., 2006). In the 2006/07 season ...Continued
