Growth Performance Of Lambs Under Discussion
THERE was no doubt that in ■* CCCbflt . years there had been a tremendous upsurge in meat production, Mr K. G. Haughey, senior veterinarian of the Ashburton Veterinary Club, said at the Rakaia winter farm Course this week, but fundamentally it was due to mote sheep'being hifi on more HeMwatfifife laltd. had been brought Into Use, This triiant that the efficiency of the ffiAfiS Of production had been impfflVed blit little attention had been given to improving the efficiency of the animal. centages of seconds in the kill at the Fairfield freezing works over a aeries at years, These iMieated that la some seasons nfor-e titan 46 per Cent of all iaffifis Weffe seconds and that the ptfcental of seconds Increased as toe kitting season advanced. Mr Haughey also pointed out that lambs killed Ute ■to the stason WCte nd heavier thin those 'killed earlier 6nd Wert Often lighter, In those respects he taid that the perforffianee of New Zealand lames had not changqd much Since 1908.

The tame approach had beeh made hi the American beef industry and on a small scale it had been started in New ZeaUhd. Similarly the Lahdraice

The best that Could be done in New Zealand was 31b*a Week.
Td a questioner Mr. Haughey said that one Of the main reasons why New Zealand lambs did not grow well might be that they did. not have the ability to grow.

Mr M. R. Hill, a Scientific officer at the Wihchmore irrigation Research Station, said that at the Hurley research • station in Berkshire a worker reported that the average weight gain of his single lambs at 28 days Was 241 b, The lambs from good mothers put oh SOIB ahd those Which the Worker Classified as poor indeed put on 2Blb..The average gain for all single Romney lambs dropped St .Winehffiore last season was Ohly 181 b to 28 days. It WHS in the pte-weaning stage that the weakness of New Zealand tombs lay and as this was due to the milking ability of the eWes it opened up another ex.tTemely important field of research. he said.
