Study of tsetse flies (Glossina spp.) and their maintenance in laboratory colonies
(University of Edinburgh, 1969)This thesis describes the methods used in the establishment and maintenance of four closed colonies of the tsetse fly (Glossina Weidmann). The pupae were sent by air from Africa or from the laboratory colonies in Lisbon ... -
Effect of sex hormones and egg formation on the feeding behaviour of the domestic hen
(University of Edinburgh, 1969)Two approaches were made to a study of the effects of reproductive factors on the feeding and drinking behaviour of Brown Leghorn fowls. The first was an attempt to decide whether any of the physiological events involved ... -
Study of the effects of chemical and mechanical treatments on perennial grass weeds
(University of Edinburgh, 1969)Results of greenhouse studies on rhizomes of couch Agropyron repens indicated firstly, their role in providing plant nutrient reserves for future propagation by viable buds and secondly, as carriers of these viable buds. ... -
Effect of ovariectomy and anabolic steriods on growth and carcase composition in beef heifers
(University of Edinburgh, 1968)Twenty-eight Hereford x Friesian heifer calves agec 3 months were submitted in a 2 x 2 factorial design to two main treatments namely ovariectomy and anabolic steroid administration. Ovariectomy (spaying) was performed by ... -
Acute fasciolasis in sheep
(University of Edinburgh, 1968)The dissertation begins with a general introduction and a review of the literature on acute fascioliasis in sheep. The various techniques used in this study are outlined, with emphasis on those modified during the work. ... -
Social behaviour of immature adults of two species of locust, Schistocerca gregaria (Forskål) Locusta migratoria migratorioides (Reiche and Fairmaire)
(University of Edinburgh, 1968)Experiments were carried out to determine if the social behaviour of immature Schistocerca gregaria adults, like that of hoppers, was affected by the conditions of population density under which they had been reared ... -
Effects of sheep wintering on subsequent production from pasture
(University of Edinburgh, 1968)1) Four winter grazing treatments (control - rested, grazed November and December, grazed January and February, and grazed November to February at ewes per acre) were applied to lambing Field 1965-66 and Anchordales 1966-67. ... -
Use of liquid anhydrous ammonia as a fertilizer
(University of Edinburgh, 1968)(1) At rates of 40, 80 units N/ac. in field, experiments and at rates of 45 , 90, 180 , 720, and 1440 lb. N/ac. in the greenhouse experiment, sulphate of ammonia proved a better source of N for grass D.M. yield than ... -
Studies on the feeding behaviour of the domestic fowl
(University of Edinburgh, 1966)This study was preparatory work for a much longer period of research, the aim of which is to make a detailed study of the feeding behaviour of motivationally abnormal chickens. The conditions of aphagia and hyperphagia are ... -
Effect of climatic and nutritional factors upon the pregnant ewe
(University of Edinburgh, 1965)If a lowground ewe flock is to justify its inclusion in an up to date farming system, maximum output from it must be achieved. This output will be mainly in the form of lambs, wool sales being of much less importance. ... -
Genetics of health and fertility in dairy cattle
(The University of Edinburgh, 1997) -
Effects of nutrient modification on two bone disorders on poultry
(The University of Edinburgh, 1995) -
Role of follicular fluid proteins in the control of gonadotrophin secretion and follicular development in the heifer
(The University of Edinburgh, 1991) -
Role of growth hormone, insulin-like growth factor-I and insulin in the control of ovarian follicular growth and development in the heifer
(The University of Edinburgh, 1992) -
Defining mechanisms of neurodegeneration associated with protein misfolding diseases
(The University of Edinburgh, 2015-11-27)Protein misfolding diseases (PMDs) are a broad group of disorders including Alzheimer’s, Parkinson’s and prion diseases. They are characterised by the presence of aggregated, misfolded host proteins which are thought to ... -
Detecting ancestral junctions in inbred populations
(The University of Edinburgh, 2005) -
Genetics of bovine vaccination
(The University of Edinburgh, 2011-06-27)Infectious disease is an important issue for animal breeders, farmers and governments. Solutions to control infectious disease are needed and research focused on the genetic loci determining variation in immune-related ... -
Functional analysis of the non-coding RNAs of murine gammaherpesvirus 68
(The University of Edinburgh, 2010)Murine gammaherpesvirus 68 (MHV-68) is used as a model for the study of gammaherpesvirus infection and pathogenesis. In the left region of the genome MHV-68 encodes four unique genes, eight viral tRNA-like molecules ... -
Animal sentinel surveillance: evaluating domestic dogs as sentinels for zoonotic pathogen surveillance
(The University of Edinburgh, 2010)The capacity of zoonotic pathogens to infect multiple hosts creates surveillance challenges but also provides opportunities to gather data from animal species that can be used to understand risks to human health. This ... -
Assessment of genetic markers for the improvement of beef quality and consistency
(The University of Edinburgh, 2010)The overall aim of this thesis was to investigate the genetic control of beef quality in a commercial population of Aberdeen Angus-sired cattle with a view to trait improvement. The population studied included 500 ...
