Thirty lactating NZW rabbit does were divided into 6 groups according to environmental temperature (5, 15, 23 and 30 °C) and to feed intake (ad libitum /A/ and restricted /R/). The does were kept at 20 °C during pregnancy and at kindling they were put into climatic chambers at a temp. of 5, 15, 23 or 30 °C. One part of the does were fed ad lib. (5A, 15A, 23A and 30 A) the others were all kept at 15 °C but they were fed the same (restricted) volume of pellet as the does' intake at 23° or 30° (15/23R and 15/30R). On comparing the groups of rabbits kept at 23° and 30 °C fed ad lib. (23A and 30 A) and that of data obtained for 15/23R and 15/30R it was observed that the daily milk yield decreased by 7.8 and 5.1 per cent, daily water intake increased by 8.4 and 13.3 per cent, and the feed/water ratio was higher by 0.18 and 0.18 respectively.
