概括

以为基础的浸泡程序改善了牛奶的喷射和流动,而不是仅仅使用消毒巾. 这种乳头制备方法使得在挤奶的早期产生更多的牛奶,并及时减少了挤奶单位.

科学领域:

乳制品科学乳制品科学
动物养殖动物养殖
兽医医学兽医医学兽医医学

背景情况:

乳房准备对于乳房健康和奶制效率至关重要.
传统的方法包括浸泡和擦拭,对牛奶的下降和流量产生不同的影响.
这项研究探讨了浸泡与擦拭程序的有效性,而无需进行森林砍伐.

研究的目的:

为了比较基于的预浸和纸巾 (浸泡程序) 与专有乳头擦拭 (擦拭程序).
评估对延迟牛奶喷射和乳末真空的影响.
为了评估对牛奶流量参数和双式挤奶模式的影响.

主要方法:

在荷尔斯坦的一个奶牛群 (195头奶牛) 上进行了8次试验性挤奶.
牛奶计记录了产量,按时挤奶单位 (MUOT) 和牛奶流量.
数字真空记录仪测量了乳头水平的真空;分析了1,287个奶牛的数据流量,96个真空.

主要成果:

浸泡程序在前2分钟增加了3.37%,减少了4.38秒的MUOT.
两种方式奶的几率是1.6倍高的擦拭例行程序.
浸泡例行结果是后面的口腔中平均真空值低于2.69kPa,前面没有差异.

结论:

浸泡程序 (预浸泡和纸巾) 改善了牛奶喷射和流动动力学.
这种乳头制备方法优于单独的消毒巾片,可以优化奶性能.
结果表明,当实施浸泡和擦拭协议时,乳牛群可以获得显著的益处.

The Mammary Glands

The female breast is a hemispheric projection of variable size positioned anterior to the pectoralis major and serratus anterior muscles. A fascia layer composed of dense, irregular connective tissue connects it to these muscles.
Each breast features a pigmented projection known as the nipple, through which milk emerges via closely spaced openings of ducts, referred to as lactiferous ducts. Surrounding the nipple is a circular pigmented area of skin named the areola, which appears rough due to...
