MORE LAMBS PER EWE
Some Wairarapa farmers are achieving more lambs per ewe after a successful research project that aimed to boost the
farmers' returns. The three-year project, supported by Technology New Zealand, entailed giving the ewes a vaccine to
produce more eggs, vaccinating them against abortions and scanning them ultra-sonically. "It has redirected our efforts
to where we can make the biggest and easiest gains," says the chairman of the 30-farmer group, Andrew Pottinger. The
pregnant ewes are scanned with ultra-sound gear. "Those with more than one lamb are separated from the rest and given
better treatment," he says. "That means the best paddocks and the safest country for lambing and better feeding." Mr
Pottinger says the single-lamb ewes will be more likely to be culled from the flock. "It sounds ruthless, but you have
to put your feed where your returns are." He believes that most of the farmers would have achieved significantly more
lambs - perhaps 20 to 30 percent. "And we've done this despite a drought for some of us out towards the coast. On the
other hand, the guys up around Eketahuna and Pahiatua have had to manage lamb survivors in very wet areas. They've had
some really wet springs." Neil McLaren, Agriculture New Zealand farm adviser for the project, says the project
undoubtedly improved farm management, "identifying what was hindering or restricting the birth potential of lambs". "So
farmers had to look at their abortion rates, ewe and lamb weights, feed, and, of course, how to manage in sometimes
difficult climatic conditions - whether in a drought or in the wet." Mr Pottinger says his group had to do something to
improve profitability. "Money is in lamb at present, not in wool." Technology New Zealand is the Government agency that
invests in research into new products, processes or services as part of a plan to fashion a knowledge-based economy.
