ItemNutritional studies of the young lamb( 1967)This thesis is based on original research work in a subject approved by the Faculty of Agriculture and is submitted under regulation 3.28 Section 6(a) of the conditions relating to the degree of Master of Agricultural Science. The experiments presented have been published in the Australian Journal of Experimental Agriculture and Animal Husbandry or in the Proceedings of the Australian Society of Animal Production. They were conducted while the author was a member of the Victorian Department of Agriculture which provided the facilities for this work. The first chapter of the thesis is a review of the literature on the digestibility of milk and solid food by the young ruminant - more specifically the calf and the lamb. The second chapter describes two experiments on the apparent digestibility of ewes milk and dried pasture by young lambs and the third chapter comprises two experiments relating to the effect of milk intake on the pasture consumption of lambs. The fourth chapter reports observations on the diet selected by grazing lambs in relation to older sheep. I was responsible for the design of this experiment, was actively associated with the field work and prepared the manuscript for publication. The fifth chapter is a paper on the effect of nutritional restriction during pregnancy on the reproductive performance of crossbred ewes and the subsequent growth of their lambs. The sixth chapter provides summaries of the experiments presented.
