R.  aMilk-secretion studies with New Zealand Rommey ewes. Parts III and IV.h[electronic resource]  c1949  aMilk production is of fundamental and practical importance to the sheep industry. Reports indicate considerable differences in milking ability between ewes of different breeds as well as between ewes of the same breed. Milking capacity of ewes is dependent on both nutritional and hereditary factors, probably the nutritional factor being the more important. Under commercial farming conditions milk yield might affect not only the growth rates of ‘fat’ lambs and the quality of their carcases, but eventually also the constitution of the ewe lambs retained in the flocks for breeding purposes. It therefore appeared that milking ability of Romney ewes in New Zealand would be a matter worthy of investigation.  aCarotenes  aColostrum  aDigestibility  aEwe milk  aGrazing  aLactation  aMilk composition  aMilk secretion  aPastures  aProtein content  aReproduction  aSuckling  aLactose  aLeite  aOvino  aDeficiency  aMammary secretion  aMilk components  aPlane of nutrition1 aLOGAN, A.
