Item Studies of the coat of the Romney lamb : practical and theoretical aspects of hair morphology, with special reference to the evolution of the fleece : thesis submitted by "Bourn" [for the degree of Master of Agricultural Science](Massey University, 1940) Goot, HenryThe original purpose of the present thesis was to answer this question: "To what extent is a britch of high halo-hair abundance an indicator of the non-kemp hairiness of the fleece?" It was assumed by Dr Dry in the light of earlier observations, that, on a britch with very many halo-hairs, the large Curly Tip fibres would be very hairy, and this has proved to be so. Especially did we want to learn about the degree of hairiness on the part of the fleece near to the britch. The gradient over the body from the britch was also much in mind, all the more because the boundary between the area on the britch with very many halo hairs and the neighbouring region with far fewer halo hairs is often abrupt. The aim of the work was that just defined, but the analysis of the samples examined provided information on a number of other matters, several of which may be thought more interesting than the problem proposed at the outset. These various results are reported in this thesis.Item Space and time relations in the coat of the New Zealand Romney lamb(Massey University, 1943) Galpin, Nancy MIn a recent paper Dry (4) gives an account of the fibre type arrays - the result of an action of two forces - the prenatal check and the reducing of inherent coarseness acting on an undefined substratum which occur on the back (4) of the New Zealand Romney Lamb. Preliminary observations by Dr. Dry and myself suggested that orderly relations existed between the fibre type arrays on the back and britch positions. These observations were extended and a comparative study of the fibre type arrays occurring over the dorsal and dorso-lateral portions of the coat of the Romney Lamb has been made. Their distribution, as one was prepared to find, has proved orderly. Following naturally on this investigation came a study of the proportions of precurly-tip to curly-tip and histerotrich fibres.Item A study of the effects of undernutrition and re-alimentation on the Romney ewe : a thesis presented at Massey Agricultural College in partial fulfilment of the requirements for the degree of Master of Agricultural Science in the University of New Zealand(Massey University, 1961) Hight, G. K.No abstract.Item A study of some effects of progesterone and pregnant mares' serum (PMS) on reproductive phenomena in the anoestrous Romney ewe : a thesis presented at Massey Agricultural College in part fulfilment of the requirements for the degree of Master of Agricultural Science in the University of New Zealand(Massey University, 1955) Lamond, D. R.No abstract.Item A study of some aspects of selection for the fertility of New Zealand Romney ewes : a thesis presented in partial fulfilment of the requirements for the degree of Master of Agricultural Science(Massey University, 1963) Clarke, J. N.No abstractItem A study of some aspects of reproduction in Romney and Romney-Cheviot halfbred two-tooth ewes : being a thesis presented in partial fulfillment of the requirements for the degree of M. Agr. Sc., Massey Agricultural College, University of New Zealand(Massey University, 1953) Inkster, I. J.No abstractItem A comparative study of the effect of two stocking levels on wool follicle development and wool production of the New Zealand Romney sheep : a thesis presented in partial fulfilment of the requirement for the degree of Master of Agricultural Science in Animal Science at Massey University(Massey University, 1969) Sumner, R. M. W.No abstractItem Body composition studies on the Romney ewe : a thesis presented in partial fulfilment of the requirements for the degree, Master of Agricultural Science in the University of New Zealand(Massey University, 1960) Ulyatt, M. J.No abstractItem Cortisol metabolism in the sheep (Romney breed) : a thesis presented in partial fulfilment of the requirements for the degree of Master of Science(Massey University, 1968) Langford, Alan KeithThe metabolism of Cortisol in the normal Romney ewe was investigated by analysis of the radioactive metabolites excreted in the urine following intravenous (I.V.) administration of 4-c14 cortisol. The metabolite glucuronic!os were hydrolysed with b-glucuronidase and extracted from the aqueous medium with ethyl acetate. The neutral fraction was divided into c-19 and c-21 metabolites by sequential elution from a florisil column. Extensive use was made of T.L.C. for the separation and analysis of each fraction before the quantitation of individual components. A series of experiments was performed with, surgically modified sheep involving collection of bile and urine both after I.V. injection of 4-c14 cortisol, and after intraduodenal infusion of radioactive biliary metabolites obtained from I.V. administration of 4-c14 corticol. The metabolites collected at each stage were analysed both qualitatively and quantitatively. The urine collected each hour for 18 consecutive days from a normal sheep, was subjected to colorimetric determination for a-ketol and 17-ketogenic steroid content. The data obtained was analysed for diurnal variation in chromogen output, and the daily secretion rate of cortisol was estimated.Item Meat studies in the Romney ewe (in two parts) : a thesis presented in partial fulfilment of the requirements for the degree of Master of Agricultural Science in the University of New Zealand(Massey University, 1957) Kirton, Alan HenryNo abstract
