USE OF HYDROALCOHOLIC EXTRACT OF Schinus terebinthifolius Raddi IN PRE- AND POST-MILKING ANTISEPSIS OF THE TEAT IN DAIRY COWS

Abstract Medicinal plants have been used for centuries as an alternative treatment for health problems. Schinus terebinthifolius Raddi is a median tree that belongs to the Anacardiaceae family. The antibacterial effect of leaves extract of this plant has already been demonstrated. The objective of this study was to test a substance derived from this plant to be used in pre- and post-milking teat antisepsis. The hydroalcoholic extract of Brazilian pepper tree was used in opposite quarters for twelve consecutive weeks, and commercial iodine was used as control. None of the indices analyzed - black background mug, CMT, intramammary infections, skin health, and teat health - showed a statistical difference between the treatments, suggesting that the plant extract can be used in pre- and post-milking teat antisepsis, as a substitute for conventional products for herds in an agroecological production system.

摘要 数个世纪以来，药用植物一直被用作健康问题的替代治疗手段。巴西胡椒木（Schinus terebinthifolius Raddi）是隶属于漆树科（Anacardiaceae）的中等体型乔木，其叶片提取物的抗菌活性已得到证实。本研究旨在评估源自该植物的一种物质在挤奶前后乳头消毒中的应用效果。实验中，研究者将巴西胡椒木的水醇提取物应用于对侧乳区，连续处理12周，并以商用碘制剂作为对照。经检测的各项指标——黑背景奶杯检测、加州乳腺炎试验（CMT）、乳腺内感染、皮肤健康状况以及乳头健康状况——均未显示两组处理间存在统计学差异，这表明该植物提取物可作为挤奶前后乳头消毒的替代药剂，用于农业生态生产系统（agroecological production system）下的畜群养殖，以替代传统消毒产品。
