Colostrum contains higher amounts of vitamins D3 and E than mature milk. Due to the structural feature of the goat placenta, goat kids are born with very low reserves of fat-soluble vitamins and must rely on colostrum to acquire adequate plasma levels of vitamin D3 and vitamin E. In the present study, vitamin E was measured in the form of α-tocopherol which is the most dominant isoform present in milk samples. The main aim of the present study is to determine the colostrum vitamin D3 and E content in Honamli and hair goats in the early postpartum stage by high-performance liquid chromatography. Five Honamli and five hair goat colostrum samples were collected on the day of kidding and on the third and fifth days postpartum. On the sampled days, the colostrum of both goat breeds contains higher concentrations of vitamin D3 and α-tocopherol than that in mature milk (p< 0,05) and there was the existence of a breed difference in colostrum vitamin D3 and α-tocopherol concentrations (p< 0,05) was determined. Also, the effect of sampling day on colostrum vitamin D3 concentration in samples that were obtained between the first and third days was also significant (p< 0,05). Hair goat colostrum α-tocopherol concentrations were found to be higher than Honamli goats (p< 0,05). Additionally, there was a statistically significant difference between the sampling day and α-tocopherol content on days one and five (p < 0,05).
初乳中的维生素 D3 和维生素 E 含量高于成熟乳。由于山羊胎盘的结构特点，山羊羔出生时体内的脂溶性维生素储备非常低，必须依靠初乳来获得足够的维生素 D3 和维生素 E 血浆水平。在本研究中，维生素 E 以α-生育酚的形式进行测量，α-生育酚是乳样中最主要的存在形式。本研究的主要目的是通过高效液相色谱法测定产后早期韩莱母羊和毛羊的初乳维生素 D3 和维生素 E 含量。在产羔当天以及产后第 3 天和第 5 天收集了 5 份韩莱母羊和 5 份毛羊初乳样本。在采样日，两种山羊品种的初乳中维生素 D3 和α-生育酚的浓度均高于成熟乳（p<0.05），并且初乳中维生素 D3 和α-生育酚的浓度存在品种差异（p<0.05）。此外，在第 1 天至第 3 天之间获得的样本中，采样日对初乳维生素 D3 浓度的影响也很显著（p<0.05）。毛羊的初乳α-生育酚浓度高于韩莱母羊（p<0.05）。此外，在第 1 天和第 5 天，采样日和α-生育酚含量之间存在统计学差异（p<0.05）。
