	abstract = {Farmers have been attempting to breed whiter wool for some time using quantitative and subjective genetic selection based on phenotypic traits. The improvement of wool colour using this form of selection has achieved limited success. The advent of DNA marker maps has introduced the possibility of more directly relating phenotypic and genetic variation. Work presented here has identified a total of ten potential quantitative trait loci (QTL) that are significant at the suggestive level, and one additional QTL that approached this significance threshold that influence wool colour. There have been five putative QTL identified for base colour or challenge colour brightness. Two QTL affecting challenge colour yellowness was identified, while three QTL identified were linked to predictive colour variation. An additional QTL that affected predictive colour has also been mapped to a non-specific location on chromosome 24. Several further key areas of research need to be addressed before the DNA markers can be developed for use in the improvement of wool colour. },

	abstract = {The pattern of wool fibre and follicle development was monitored for 20 Perendale lambs from lines selected for or against wool bulk. There was no significant difference in characteristics associated with wool bulk between selection lines at birth. These characteristics followed a curvilinear pattern of development with most of the change taking place between birth and 14 weeks of age then reaching a plateau by 35 weeks. The different rate of developmental change for each bulk line meant that by 14 weeks the high line had a greater follicle curvature grade, shorter follicle length, shallower follicle depth, more para-meso cortex and a higher fibre curvature. Together fibre curvature, fibre diameter and fibre diameter standard deviation explained around 70\% of the variation in hogget wool bulk from 25 weeks of age. From these results it is suggested that the potential of a sheep to producehigh bulk wool can be assessed using fibre curvature and fibre diameter from 6 months of age which allows hogget mating and/or early culling to be practised.},

	abstract = {Forty-two identical twinsets were milked either once (ODM) or twice  (TDM) daily and offered pasture and silage, either to appetite (H) or  restricted to 50-60\% of this level (L) for the last 5 weeks of the 93/94  season. Pretreatment, uninfected cows produced 8.45+/-0.28 1 milk/d  (mean +/- S.E) with a mean somatic cell count (SCC) of 37.1+/-3.3 x  10/3 cells/ml). Milk yields were significantly reduced (P<0.001) by L  nutrition and by ODM. LogSCC was significantly increased (P<0.05) by L  nutrition, due to reduced milk volumes but was not affected by ODM.  Concentration of the serum-derived proteins, immunoglobulin G and bovine  serum albumin, increased significantly for L nutrition and ODM. This  suggests that involution had been accelerated in these animals, whose  average daily milk yield was below 5 1/d. In late lactation milking  should be discontinued for cows with milk yields of less than 5 1/d as  involution may be initiated below this yield.   },
