近年来,我国规模化养猪发展较快,但猪场环境管理、饲养管理与疾病控制之间的关系却相对滞后,造成母猪子宫内膜炎多发。母猪子宫内膜炎是母猪产后感染或隐性流产后细菌、病毒、寄生虫等病原微生物侵入母猪子宫黏膜内膜层或肌层而引起的子宫黏膜的黏液性或化脓性的炎症过程[1]。母猪发生子宫内膜炎将导致子宫复旧时间延长、产后发情时间推迟,炎性渗出物还可改变子宫内环境的酸碱度,损害精子和卵子的生存环境与受精能力,使受胎率明显下
In recent years, the rapid development of large-scale pig farming in our country, but the relationship between the farm environment management, feeding management and disease control is relatively lagging, resulting in multiple sow endometritis. Sow endometritis is the mucosal or purulent inflammatory process of uterine mucosa caused by the invasion of spermatozoa such as bacteria, viruses and parasites into the uterine mucosa intima or muscle layer after sow’s postnatal infection or tactile abortion [1]. Sow endometritis will lead to prolonged uterine involution, delayed postpartum estrus, inflammatory exudate can change the pH of the uterine environment, damage the living environment and fertilization ability of sperm and egg so that the pregnancy rate significantly
