The effect of shearing on milk yield and milk composition was studied in Tsigai ewes. The sheep were kept indoor and shorn at the beginning of April. Ewes were milked twice daily and milk samples, from the morning milk only, were taken on the day before, and on days 2 and 14 post-shearing. Shearing had no effect on daily milk yield. The concentrations of milk fat, protein and total solids on day 2 after shearing increased by 14.4, 3.6 and 11.1 %, whereas on day 14 the increase of these constituents was 18.6, 9.6 and 21.0 %, respectively, compared to the pre-shearing values. The increased percentages of milk constituents was accompanied by an increase in daily output. There was no effect of shearing on the lactose concentrations. Renneting time progressively decrease followed the increase in the concentrations of milk constituents. The possible effects of post-shearing adaptations on the observed changes in milk composition are discussed.
