Young goats of the Slovak White Short-wooled breed of Saanen type (n=80) were divided into 5 groups according to their live weight at mating. The most extreme weights were observed in groups I and II with the average weight 18.96 kg and/or 24.47 kg, the values in other groups were 28.72 kg, 31.59 kg and 33.61 kg. Average live weight of born kids was influenced to a lesser extent than the live weight of goats, but differences between the groups were statistically significant. The length of lactation period in 1996 was obviously different in group I only, where it was by more than two weeks shorter in comparison with groups III to V, and by almost 13 days shorter in comparison with group II. The most significant differences between the groups were observed in total milk production (group I 286.47 l, group II 335.15 l, group III 376.21 l, group IV 431.11 l, group V 369.72 l) while F-test value was 7.288. The rate of weight gains in kids in a postnatal period was not influenced by the presence in the particular weight groups of their mothers.
