Abstract: Abstract: The experiment was designed and carried on for verifying and mastering the general variety regulation of quail physiology and its normal body temperature. Double dependent variables, multiply factors, two tries and 6 repetitions were designed and adopted in the experiment. Chosen 12 quails, according to the sex, were divided into bisexual two tries naturally, 6 quails for each group. The environment temperature, and the relative humidity, and the body temperature under the right plumage of quail, and the frequency of breathe were tested, recorded and analyzed in day and night different time of 24 hs. The results are shown that average body temperature of quails (F, M) is 41.93 ℃ ±0.53℃.Among them average body temperature of the male quail (M) is 41.81 ℃±0.58 ℃, and the female’s (F) is 42.04℃±0.44℃. The obvious changing regularity at different time in day and night is found by still study. A day and night, the max value of average body temperature of the block on testing time is at 9:10 a.m., the mix value is at 18:00 a.p. There is significant different between them and humans or other animals which had studied by people. The normal body temperature of egg lying quails was proved on the study. It is the first discovery on vary law of egg lying quails body temperature.
