The use of a bone biopsy technique for skeletal studies with sheep is described. Histological examination of samples of pelvic bone removed at about mid-lactation from Scottish Blackface ewes grazing on two hill farms revealed little or no evidence of skeletal resorption. This was in agreement with the results of in vivo radiography carried out in this and another field experiment reported as part V of this series (Benzie, Cresswell, Duckworth, Hill and Boyne, 1961).
