The Deferred Grazing Handbook (link below) was produced in December 2020 by AgResearch to document pasture research over a three year period funded by the Ministry of Primary Industries, and done in collaboration with farmers, Beef+Lamb New Zealand, Plant and Food Research, Ballance, AgFirst and Waikato and Bay of Plenty regional councils.
Deferred grazing is a management tool to maintain pasture quality on pastoral farms from mid-spring onwards. It involves dropping some paddocks out of the rotation to optimise grazing pressure on the remaining paddocks, so pasture quality is maintained. The research carried out by AgResearch and partners produced some impressive results.
AgResearch played a key role in saving New Zealand up to $133 million a year in control costs, with a world first eradication of the invasive Great White Butterfly.
AgResearch scientists discovered a gene which means more lambs with little extra effort for farmers.
AgResearch has shown sheep milk has real benefits for gut health. Studies like this help grow New Zealand industries.
AgResearch scientists helped develop The Wool Runner, "the world's most comfortable shoe".
AgResearch's decade-long research into neonatal lamb deaths identified key genetic, maternal and environmental factors affecting lamb survival – all of which has changed farm practices and improved survival rates.
AgResearch has contributed $5m to the establishment of the world-class Southern Dairy Hub, which provides quality science to support the future of dairy farming in Southland and South Otago.
