Theobjective of the study was to measure bovine uterinetemperature (UT) by a novel IC thermometer (IC). Data wascompared with conventional rectal (RT) and vaginaltemperature (VT). IC is a chip housed in a button shapedstainless steel enclosure, 15 mm in length, 5mm in width with arange of +15 to +46°C in 0.125°C increments. It was calibratedwith a standard mercury thermometer, and was also correlatedwith a rectal thermometer installed with a sensor probe (0.1°Cprecision). UT was measured in 20 min intervals for 4 weeks,while RT and VT were measured every 4 hr. Eleven JapaneseBlack cows, 8 in the summer and 3 in the winter weresubjected to caesarian section (CS). By trans-lumbarlaparotomy, IC was installing in the left uterine horn proximateto the uterotubal junction during CS. After recording for 4weeks, IC was removed by 2nd CS and mounted on the chipreader in the PC. The accumulated data were analyzed byANOVA for repeated measures. Ambient temperature (AT) wassimultaneously recorded. In 5 cows, blood was daily collectedfor hormonal (estradiol) assay and underwent ultrasonographyto monitor ovarian dynamics. Temperature after operation wastemporarily elevated for 4 days (0.14°C) and excluded.Averages in UT, RT and VT in the summer (AT: 28.76°C) were38.57 ± 0.23°C, 38.67 ± 0.23°C, 38.60 ± 0.35°C, and those inthe winter (AT: 14.46°C) were 38.63 ± 0.21°C, 38.68 ± 0.21°C,38.67 ± 0.20°C, respectively. UT was significantly lower thanRT or VT, and UT in the summer was lower than in the winter(P < 0.01). Diurnal rhythm was observed at all three temperatures, lowest at 08:00 and highest at 20:00 h. Uponovulation, UT in the luteal phase was significantly higher (38.61± 0.20°C) than in the follicular phase (38.51 ± 0.22°C, P < 0.01),whereas no difference was observed in RT or VT. Inconclusion, IC placed in the uterotubal junction successfullymeasured UT and detected diurnal rhythm. UT fluctuation wasstable, but showed a hyperthermia in luteal phase. It appearthat IC device can be use to monitory uterine temperatureduring estrus cycle and probably in some other reproductivephysiology processes in cows 2006 artículo científico 0798-2259 https://www.redalyc.org/articulo.oa?id=95916409 en http://www.redalyc.org/revista.oa?id=959 Revista Científica application/pdf Universidad del Zulia Revista Científica (República Bolivariana de Venezuela) Num.4 Vol.XVI |
