Our objective was to analyze the changes in fatty acid (FA) profiles of bovine colostrum and immature milk during the first four days of lactation and assess their potential impact on human health. Colostrum and immature milk samples were collected from Czech Fleckvieh cows during their first to third lactation and the FA profiles were analyzed using multidimensional gas chromatography with a vacuum ultraviolet detector (GC×GC-VUV). The colostrum of primiparous cows contained lower levels of medium-chain and saturated fatty acids, and higher levels of mono- and unsaturated fatty acids compared to that of multiparous cows. The atherogenic and thrombogenicity indexes, as well as the hypocholesterolemic-to-hypercholesterolemic fatty acid ratio, were more favourable in primiparous cows. This makes colostrum fat an attractive product for human nutrition. To obtain the maximum health benefits, we recommend collecting and processing the colostrum of primiparous cows and immature milk at the end of the milk transition separately.
我们的目标是分析奶牛初乳和未成熟乳在泌乳期前四天的脂肪酸（FA）谱变化，并评估它们对人类健康的潜在影响。从捷克弗莱维赫奶牛第一至第三胎次收集初乳和未成熟乳样本，并使用带有真空紫外检测器的多维气相色谱法（GC×GC-VUV）分析脂肪酸谱。与经产奶牛相比，初产奶牛的初乳中中链和饱和脂肪酸含量较低，单不饱和和多不饱和脂肪酸含量较高。初产奶牛的致动脉粥样化和血栓形成指数以及降胆固醇与升胆固醇脂肪酸比率更有利。这使得初乳脂肪成为人类营养的有吸引力的产品。为了获得最大的健康益处，我们建议分别在乳汁转换期结束时收集和加工初产奶牛的初乳和未成熟乳。
