Milk yield in goats was influenced by environmental conditions connected with the calendar year. Daily milk production was observed to decrease with progressing lactation, while an increase was observed in SCC, as well as percentage fat and protein contents, while the lactose content in milk decreased. No significant influence was found of birth type, number of kids born or reared on the qualitative and quantitative parameters of milk yield and lactation duration. Goats in their fifth and further lactations produced over 15% milk less compared with figures recorded in a medium-sized flock (248.9 and 2942.3 ml, respectively). Goat milk contained almost 67% more somatic cells (log 6.099 and log 5.877, i.e. 1260 × 103 and 755 × 103 cells/ml).
