Summary:Investigation was carried out on 45 French Alpina goats in the 1st, 2nd and the 3rd lactation. Animals were kept in indoor-outdoor system. Milking efficiency control has been conducted from 30th day after weaning during 6 months, in periods of one month. In the first lactation goats produced significantly lower (P<0.01) milk (288.26 kg) than in the second (381.58 kg) and the third lactation (382.96). Statistically higher milk fat content (P<0.01) was determined during the first lactation control in relation to all other controls. Milk fat and protein content were higher during the 1st lactation compared to the 2nd and the 3rd ones, but without statistical significance (P>0.05). Statistically lower (P<0.05) number of somatic cells in the 1st lactation in relation to 2nd and 3rd ones, as well as in the 2nd in relation to 3rd lactation was determined. Number of somatic cells (SC/ml) on the average was the lowest in the 1st control, but later values of SC/ml increased. The results show that number and stage of lactation have significant influence (P<0.01) on milk quantity, as well as on chemical composition.
