“…Thirty days prior to the start of data collection, each mare was implanted with hermetically sealed miniature radiotransmitters (Fryer et al, 1966). The transmitter for body temperature was implanted on the inner left abdominal wall via a flank incision.…”

“…For the first four birds studied the telemetry system used was based on a conventional thermistor-pulsed oscillator combination (Winget et al 1965;Fryer et al 1966;Mackay 1968;Riley 1970;Cain and Wilson 1971) but with some variations designed to reduce implant size and increase service life and sensitivity. This system was provided for us by Mr B. H. Ridley.…”

Continuous temperature records in relation to time of oviposition and behaviour associated with it are summarized for 13 laying strain pullets with a regular pattern of oviposition and for a further 10 pullets which were either 'internal layers' , or natural or induced layers of membranous-shell eggs. The records of five pullets, in which the most recently ruptured follicle was excised within 2-5 h after ovulation, and of four control pullets are also included.The previously reported finding that a temperature peak normally occurs at oviposition is confirmed. However, no evidence could be found for the regular occurrence of twin temperature peaks (for ovulation and oviposition), or for other direct temperature indicators of time of ovulation.The 'oviposition' temperature peak is always accompanied by characteristic pre-laying behaviour, even in the absence of the oviposition due to occur at that time. Like the pre-laying behaviour, the temperature peak is shown to be a consequence of the ovulation event of the previous day; more precisely it is shown to depend on the presence of the intact ruptured follicle from which the ovum was shed.It is concluded that the timing of a sequence of ovulations may be inferred, therefore, from the pattern of temperature peaks and this method is being used to study unusual ovulation-oviposition patterns occurring in some of our selection lines.Some preliminary observations are also reported on the effects of injection of oxytocin, vasopressin or progesterone on body temperature.

“…Because of marked improvement in design, particularly the reduced size (Cain and Wilson, 1971;Fryer et al, 1966;Winget et al, 1965), there has been an increase in the use of radio transmitters for evaluating body temperatures of birds. Miniature radio transmitters were surgically implanted in Single Comb White Leghorn (SCWL) males in experiments designed to determine the effect of ambient temperature on body temperature biorhythms and results are presented here.…”

Adult, male Single Comb White Leghorn chickens (SCWL) were housed unrestrained in individual cages in a controlled environment room with a photoperiod of 12L:12D. By means of surgically implanted radio transmitter, body temperatures were recorded hourly for five consecutive days at each of six experimental temperatures: 23, 26, 29, 32, 35, and 38 C. The data were evaluated statistically by correlogram, periodogram, and harmonic analysis. Period length of each cycle was about 24 hr at all ambient temperatures. No significant differences in deep body temperature were observed until the ambient temperature reached 32 C; but highly significant increases were detected between 32, 35, and 38 C. Diurnal differences in body temperature ranged from .6 to 1.1 C. It has been suggested that the body temperature of male chicken may be under the control of a biological clock that synchronizes with the solar day.
