Sažetak

Individual milk samples from the evening and morning milking, of 10 Alpine goats, were taken twice a month from June to November 1999. The goats were in the third month of lactation. 200 milk samples were analysed for standard plate count, coliforms, proteolytic bacteria, sporeforms and chemical composition. Milk production was followed individually for each goat. Milk contained on average 5,65x100000 cfu/mL of total count, 2,04x10000 cfu/mL of coliforms, 3,57x10000 cfu/mL of proteolytic bacteria and 20 cfu/mL of sporeforms. Daily milk production decreased during the first month of milking (the third month of lactation) and then remained constant. The average milk production was 1177 mL/doe/day. Concentration of all measured milk components (fat, total protein, solids non-fat and total solids), with the exception of lactose, increased slightly. Overall mean of chemical composition was 3.33 % fat, 2.69 % total proteins, 4.14 % lactose, 7.63 % solids non-fat and 10.96 % total solids.
