Space and time relations in the coat of the New Zealand Romney lamb
(Massey University, 1943) Galpin, Nancy M
In 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.
A study of the plateau array : thesis concerning subsection (e), 608 of the Animal Husbandry Section of the Master of Agricultural Science Degree and incorporating work carried out during the tenure of the Farmers' Union Research Scholarship and the Shell Scholarship1938
(Massey University, 1939) Sutherland, J. A. (James Alan)
A brief historical survey of the work leading up to the present study. The world sheep population is in the vicinity of seven hundred millions and the vast majority of these animals are kept, to a greater or a lesser degree, for their wool. It is, therefore, not surprising that Wool Research is by no means new. The production of sheep for their coat has been, as Barker points out ( 1), of importance since Biblical times and, although during the last epoch, with the perfection of methods for meat preservation, the importance of wool to the sheep industry has decreased, the need for wool research has been increased by the ever growing perfection of synthetic fibres. Wool research as such can possibly be dated from Dr. Hook who, in 1664, presented a paper to the Royal Society on the subject of wool and hair structure, but it was not until the advent of the compound microscope that the study of wool gained sufficient precision for measurements to be made. Such measurements opened the door for the wool physicist who, by the application of x-rays and other physical methods, has been able to explore with considerable success the ultimate structure of wool and hair. The value of wool has been determined, at least partially, by its length and thickness (or width), and thus measurements of wool in three dimensions have been important sections of wool research. As other valuable characters were recognised and evaluated they also were measured and correlations worked out. Thus it has come about that wool research has collected about itself innumerable patient measurements - measurements that have often merely evidenced the complexity of the fleece of the sheep as a subject of research.
Cannon bones : some dimensions, heritabilities and relationships to carcass quality in Romney wether lambs : a thesis presented in partial fulfillment of the requirements for the degree of M. Agr. Sc.
(Massey University, 1957) Hughes, Alan Herbert
In the past and to a certain extent at the present time sheep breeders have paid considerable attention to the dimensions of the cannon bones of their animals in the belief that this bone serves as a good indicator of the quality of the conformation and constitution of their animals. Scientific workers interested in meat and carcass quality have also attached considerable importance to the cannon bone as an index of carcass composition and hence of carcass quality. The origin of the sheep breeders beliefs is no doubt due to years of farmer observation supported to some extent by the findings of the scientific workers, who of necessity, using relatively small numbers of animals, have established relationships between the dimensions of the cannon bone and other characters of' economic importance. The existence at Massey Agricultural College of complete records, concerning cannon bone dimensions and carcass quality, collected from a relatively large number of animals, prompted this present study which was intended to yield more accurate results than those previously reported. At the same time this study was designed to yield estimates of the heritability of cannon bone dimensions and their relationship to carcass quality thus providing a basis on which breeders might decide whether or not they could continue to place the present amount of emphasis on the cannon bone in their selection practices .
Investigations into some effects of cysteine administration to the New Zealand Romney : a thesis presented in partial fulfilment of the requirements for the degree of Master of Agricultural Science in Animal Scienc
(Massey University, 1968) Dryden, Gordon McLean
The Present Work: Up to this date, all sulphur containing amino-acid and protein infusion work had been done in Australia using Australian Merinos. It was decided to conduct a similar experiment to see whether cysteine infusion had a similar effect on the wool grovvth rate of New Zealand Romneys. The work described in this thesis consists of two parts:- (i) a preliminary experiment was conducted to see if the Romney wool growth rate responded to cysteine infusion, and if so, at what dose levels. A first investigation of the wool factors involved was also made. (ii) having found that the Romney did respond to cysteine treatment a second experiment was carried out to determine more exactly the wool factors involved in the response and to see if the response was altered by the protein content of the basal diet. The effect of cysteine administration on the digestibility of basal diet was also examined. [From the Introduction]
