Conteúdo: 	Body reaction data were obtained on 18 calves belonging to the herd of Alexandria University. These were buffalo, bative cattle and cross-bred cattle calves. They were kept inside the byre and the observations on body temperature and respiration rate together with the corresponding dry and wet bulb temperatures were taken five times daily; at 8.30 a.m., 10.00 a.m., 11.30 a. m., 1.00 p. m and 2.30 p. m., for 136 days between 21 December 1961, and 25 Janauary 1963. The data obtained during the summer months were more intensive. The results obtained can be summarized briefly as follows: There was a wide range of variations between and within groups of calves in their body reactions. The body temperatures of buffalo, native cattle and cross-bred calves were 38.18. 38.31 and 38.40C, and the respiration rates 7.54, 8.08 and 10.11 counts per half-minute for the three groups respectively. The rate of increase in the respiration rates with increasing air temperature was more obvious in the cross-bred than it was in the other calves. Air temperature variations were more important than relative humidity in causing variations in body reactions. There were variations between animal reactions made on different days and at different times of the same day. There were highly significant correlations between respiration rates and air temperatures.The repeatability estimates obtained among consecutive readings of body reactions were generally of a high order. The repeatability between daily separate tests was high in the early readings of body temperature for buffalo calves.
