【摘要】 四、五月份,观察二花脸猪、长白猪、约克夏猪的行为性体温调节反应,以探求其耐热性和体温调节特性。直肠温度与环境温度及体感温度均呈正相关随之升高而上升,且二花脸猪的直肠温度偏低,二花脸猪静立时间为19.4±12.4分/小时显著地长于长白和约克夏猪(P<0.05).更多还原

【Abstract】 The thermoregulatory behaviour of boars of Erhualian, Landrace and Yorkshire were compared in order to explain breed differences in heat tolerance in April and May. The rectal temperature increased (P<0.01) with the increase in environmental temperature, and was breed in every day the Erhualian was low-level. The amount of time engaged in quiet-standing activity of Erhualian increased significantly than Landrace and Yorkshire (P<0.05).更多还原
