Conjugated linoleic acid (CLA) content of ruminant milk reported in published research papers (n = 65) from January 1995 to March 2020 around the world were analyzed to estimate the overall mean CLA value. The CLA content of ruminant milk samples was grouped according to geographical regions (Europe, South America, North America, Oceania, Asia, and Africa). The total CLA content of milk samples from cows, sheep, goats, yaks, and llama retrieved from the collected data ranged between 0.06 and 2.96% of total fatty acids. There is a wide variation of pooled estimated mean content of CLA in milk among the study regions and were highest in Oceania with 1.33% (95% confidence interval (CI): 1.16 - 1.49%) of total fatty acids. Though several factors have been reported to influence the CLA content of milk, the effect of the "geographical origin" was only considered in the present manuscript as one of the main factors in this respect.
对 1995 年 1 月至 2020 年 3 月期间世界各地发表的研究论文中报道的反刍动物乳中共轭亚油酸（CLA）含量（n=65）进行了分析，以估算总体平均 CLA 值。根据地理区域（欧洲、南美洲、北美洲、大洋洲、亚洲和非洲）对反刍动物乳样中的 CLA 含量进行了分组。从收集的数据中检索到的来自奶牛、绵羊、山羊、牦牛和羊驼的乳样中的总 CLA 含量占总脂肪酸的 0.06%至 2.96%之间。研究区域中乳中 CLA 的平均含量存在很大差异，大洋洲的平均含量最高，为总脂肪酸的 1.33%（95%置信区间（CI）：1.16-1.49%）。尽管已经报道了许多因素会影响乳中 CLA 的含量，但在本研究中仅将“地理起源”作为影响 CLA 含量的主要因素之一。
