Abstract
   The studies were performed on milk samples collected from 178 Carpathian females belonging to a farm from southeastern Romania. The females were grazed daily, benefiting from natural pasture, specific to the Dobrogea area. Before each milking, 100 g of special granules for goat's milk were administered. After weaning (April), the goats were milked twice a day for 5 months. Milk production control was carried out monthly, after the weaning of the kids, for three consecutive months, starting with May. For this, the amount of milk milked in the morning and in the evening was weighed individually. The computation of the total individual production was calculated by applying the Fleischmann formula in the case of milking the goat after a period of lactation, when the first milking is done after the flat-rate date of the end of lactation. For primipara, the total individual milk production was between 124.35 kg and 199.76 kg with an average of 164.93 kg/head/day. At multipara, the average total individual milk production was 168.32Kg. Biochemical parameters (fat, protein, lactose) were analyzed by ultrasonic method in a standardized analyzer for goat's milk. At primipara, the fat concentration reaches a maximum of 3.12 g% in July, and at multipara 3.36g% in June. The protein concentration had values between 2.87g and 3.08g% at primipara and between 2.90g% and 3.22g% at multipara. The results of our analyzes recorded a maximum of 4.36% for lactose in June for primipara and 4.58g% for multipara. The percentage of mineral substances varies between 0.65 g% and 0.67 g% at primipara and between 0.64 and 0.65 g% at multipara.
