In goats (Capra) the growth and functional development of certain parts of the multi-chambered stomach continue during the first few months after birth. The aim of this research was to clarify live weight gain and morphofunctional changes in the kids stomach during the first 60 days of life. In research we used Saanen breed kids. In total 20 goat kids were used in the research. In first group (DMG) were kids which were fed with dairy (mother) milk ad libitum and lived with mothers (n=10), second group (MRG) kids were fed with milk replacer and lived separate from mothers in cote (n=10). Each kid before slaughtering was weighed (at day 45 and 60). The stomach complex were collected after slaughter, weighed full and empty (abomasums; reticulorumen with omasum), and immediately processed for morphological analyses. Length of rumen on day 45 was 21±1.1 cm, but on day 60 the average length was 25±0.8 cm. Rumen width on day 45 was 23±0.8cm, but on day 60 - 25±1.0 cm. In kids which were fed with dairy milk the length of abomasum (curvature minor) on day 45 was 22±0.9 cm, but MRG at day 45 was 18±0.7 cm. The relative stomach weight (p is less than 0.05) on day 45 was 6.01±0.004% in MRG and 4.98±0.005% DMG, while on day 60 in MRG it was 5.57 ±0.001 % and in DMG 5.88 ±0.11 %. In MRG kids full abomasum weight (p is less than 0.05) was 112 ±15.5g, but empty 30±2.54g and rumen full weight was 1174.4±39.70g, empty 144±11.22g, while in DMG full abomasum weight was 255.6±5.50g, but empty 69±4g, and rumen full weight was 1739±131.7g, empty 225.4±7.05g. Similar dynamics were found by other authors, so feeding of milk replacer, which was intended for calves, not affect growth of kids stomach in the first two month of life.
