The colostrum bacteriome of primiparous (P) and multiparous (M) Holstein cows was analysed by 16S rRNA sequencing. The species richness (Chao 1), diversity (Shannon and Simpson), and beta diversity did not differ between cow groups. The phyla , , and were more abundant in M cows, while , , and were more abundant in P cows. At the genus level, no significant differences were observed between groups ( < 0.05), and _1 was the most abundant taxon. P and M cows shared 1030 taxonomic operational units (OTUs), with showing greater abundance. In conclusion, parity did not affect the colostrum bacteriome of P and M cows and a healthy mammary gland could represent a reservoir of in dairy farms.

通过16S rRNA测序分析了初产（P）和经产（M）荷斯坦奶牛的初乳细菌群落。奶牛组之间的物种丰富度（Chao 1）、多样性（香农和辛普森指数）和β多样性没有差异。在经产奶牛中，厚壁菌门、放线菌门、拟杆菌门和变形菌门更为丰富，而在初产奶牛中，梭杆菌门、蓝细菌门、衣原体门和螺旋体门更为丰富。在属水平上，各组之间未观察到显著差异（P＜0.05），且未分类的_1是最丰富的分类单元。初产和经产奶牛共有1030个分类操作单元（OTU），未分类的_1丰度更高。总之，胎次不影响初产和经产奶牛的初乳细菌群落，健康的乳腺可能是奶牛场中未分类的_1的储存库。
