	abstract = {Wiltshire Horn sheep exhibit an annual moult in spring and  potentially provide a model for studies on the seasonality of wool  growth. Twelve, 1 year old New Zealand Wiltshire ewes (Wiltshire Horn  with some Poll Doreset in ancestry) were kept indoors under natural  light and fed concentrates and hay. The sheep were cored for extent of  fleece shedding every 2 weeks and skin sampled monthly for histological  determination of primary and secondary follicle activity. Follicle  activity reached a peak in summer and autumn (January to April) with low  activity over winter (May to August) resulting in partial or entire  shedding of the fleece in spring and early summer (September to  December). There was evidence of a subsidiary shedding cycle in the  primary follicles in early summer. Seasonal follicle activity was  higher and longer in duration than previously recorded in British  Wiltshire Horn ewes maintained on pasture. Four sheep with highly  seasonal follicle activity cycles were identified as suitable for  further studies on the endocrine control of wool growth. Such sheep can  be selected from skin samples collected in June, July and August when  follicle activity is at a seasonal minimum.  },
