Goats' milk includes numerous cell fragments ("christiesomes") which originate from the mammary secretory cells, contain well preserved endoplasmic reticulum, mitochondria and lipid droplets, and are responsible for the considerable triglyceride synthesising capacity of fresh goat milk. Cows' milk shows a few such particles only after repeated oxytocin-aided milkings. Cows' milk does contain quite different particles which have a dense content with a few small vesicles and numerous microvillus-like protrusions on one side ("sunbursts"). These have not been found in goats milk. Cytoplasmic particles similar to sunbursts have been found on the surface of the mammary secretory epithelium. It is suggested that they are residues of dead cells.
山羊奶包含许多细胞碎片（“克里斯蒂体”），这些碎片源自乳腺分泌细胞，含有保存完好的内质网、线粒体和脂滴，并且是新鲜山羊奶具有相当高的甘油三酯合成能力的原因。只有在反复使用催产素辅助挤奶后，牛奶中才会出现少量此类颗粒。牛奶中确实含有截然不同的颗粒，其内容物致密，一侧有一些小泡和许多微绒毛样突起（“日晕”）。这些在山羊奶中未被发现。在乳腺分泌上皮表面发现了类似于日晕的细胞质颗粒。有人认为它们是死细胞的残余物。
