In Manchega sheep, correlations between temperatures across various body regions, including the udder, under differing environmental conditions, stages of lactation, and states of mammary gland health have not been extensively explored. To address this, a group of 108 Manchega sheep was evaluated monthly over a period of six months. Ambient, rectal, lacrimal, perianal, and udder surface temperatures, alongside mammary gland health status indicators such as somatic cell count (SCC) and microbiological milk culture, were recorded. This study investigated the correlations between these temperature measurements and SCC levels. Mammary glands were classified based on their SCC (greater or lesser than 400,000 cells/mL) and the results of the microbiological cultures (more or less than five colonies in 20 µL of milk). This study found no correlation between body surface temperatures and rectal temperatures. SCC showed a low negative correlation with udder surface temperatures. Notably, mammary glands with SCC levels exceeding 400,000 cells/mL exhibited lower udder surface temperatures. This research underscores the Manchega breed's ability to adapt to varying ambient temperatures and the necessity for further studies to better elucidate the relationship between inflammation and temperature changes in the udder during intramammary infections.
在曼彻加羊中，不同环境条件、泌乳阶段和乳腺健康状况下，包括乳房在内的各个身体部位的温度之间的相关性尚未得到广泛研究。为了解决这一问题，一组108只曼彻加羊在六个月的时间里每月进行评估。记录环境温度、直肠温度、泪腺温度、肛周温度和乳房表面温度，以及乳腺健康状况指标，如体细胞计数（SCC）和微生物学乳汁培养。本研究调查了这些温度测量值与SCC水平之间的相关性。根据SCC（大于或小于400,000个细胞/毫升）和微生物培养结果（20微升乳汁中菌落数多于或少于五个）对乳腺进行分类。本研究发现体表温度与直肠温度之间无相关性。SCC与乳房表面温度呈低负相关。值得注意的是，SCC水平超过400,000个细胞/毫升的乳腺乳房表面温度较低。本研究强调了曼彻加品种适应不同环境温度的能力，以及进一步研究以更好地阐明乳房内感染期间炎症与乳房温度变化之间关系的必要性。
