摘要：
The aim of the present study was to examine the effects of non-genetic factors on scrotal thermographic profile viz., proximal pole temperature (PPT A degrees C), mid pole temperature (MPT A degrees C), distal pole temperature (DPT A degrees C) and ocular temperature (OcT) of Murrah (Bubalus bubalis) breeding bulls. A total of 109 buffalo bulls, maintained at three semen stations (SS), were monitored for scrotal surface and ocular temperatures using infrared thermography twice daily during rainy, winter and summer seasons using an FLIR i5 infrared camera and temperatures were measured. Thermograms were analysed by FLIR QuickReport v.1.2 SP2 software. Statistical analysis revealed that semen station, season, temperature humidity index (THI), housing system and timing of observations had significant (P < 0.05) effect on scrotal surface temperature (SST) and OcT. In SS-I, the PPT and MPT were significantly (P < 0.05) higher as compared to SS-II and SS-III. THI had significant (P < 0.05) effect on SST and OcT, whereas PPT (A degrees C), MPT (A degrees C), DPT (A degrees C) and OcT (A degrees C) values during high THI (> 80.88; < 0.05) period were higher as compared to medium THI period (70.06-80.88) and during low THI period (< 70.06). Temperature gradient (TG) of the testes was significantly (P < 0.05) higher during low THI period (4.50 +/- 0.06 A degrees C) as compared to medium THI (2.38 +/- 0.03 A degrees C) and high THI (1.61 +/- 0.05 A degrees C). Season of the year had a significant effect (P < 0.05) on the SST and OcT. During the rainy season, PPT (34.50 +/- 0.09 A degrees C), MPT (33.44 +/- 0.12 A degrees C) and DPT (32.11 +/- 0.15 A degrees C) were significantly (P < 0.05) higher as compared to winter and summer seasons. Age of the bulls had non-significant effect on SST and OcT but had a marked influence on thermal profile of scrotum. It could be concluded semen station, season, temperature humidity index, housing system and timing of observations had a significant influence on scrotal surface temperature. The monitoring of scrotal surface temperature by infrared thermography was found to be useful in evaluating the effects of thermal stress on physiology and health of buffalo bulls.
