【摘要】：本试验旨在分析金川县牦牛血清和被毛的矿物元素含量,探讨肋数和年龄对矿物元素含量的影响,并对被毛矿物元素含量与血清中相应元素含量的相关性进行分析。采用二因素有重复试验设计,将32只公牦牛进行分组,按照肋数[14肋(n=17)和15肋(n=15)]和年龄[0(初生)~2岁(n=10)、3~4岁(n=11)、5~6岁(n=5)、7~8岁(n=6)]共分为8组。分别采集血清及被毛样品,进行矿物元素含量分析。结果表明:1)肋数、年龄对血清中的钙(Ca)、铜(Cu)、铁(Fe)、钾(K)、镁(Mg)、锰(Mn)、钠(Na)、锌(Zn)的含量均无显著影响(P0.05);年龄和肋数间无互作(P0.05)。2)肋数对被毛Ca、Cu、Fe、Mg、Mn、Na、Zn含量无显著影响(P0.05);年龄可影响被毛K含量,7~8岁被毛K含量显著高于其他年龄段(P0.05),但对被毛其他元素含量均无显著影响(P0.05),年龄和肋数间无互作(P0.05)。3)被毛Ca、Cu、Fe、Mg、Zn与血清中相应元素含量相关性极显著(P0.01),相关系数分别为0.623 0、0.539 8、0.569 2、0.468 4、0.505 3,而K、M n、Na含量的相关性则不显著(P0.05)。综合可知,金川14肋与15肋牦牛矿物元素含量无显著差异;7~8岁被毛中的K含量显著升高;牦牛被毛、血清Ca、Cu、Fe、M g、Zn含量具有显著的相关性,可由被毛代替血清测定相应的矿物元素含量。
[Abstract]:The purpose of this experiment was to analyze the contents of mineral elements in serum and coat of yak in Jinchuan County, and to explore the effect of rib number and age on the contents of mineral elements, and to analyze the correlation between the contents of mineral elements in hair and the contents of corresponding elements in serum. 32 male yaks were divided into three groups according to the number of ribs [14 ribs (n = 17) and 15 ribs (n = 15)] and the age [0 (newborn) ~ 2 years (n / 10), 3 / 4 (n / 11), 5 / 6 (n / 5), 2-2 years old (n = 10), 3 / 4 years old (n / 11) and 5 / 6 years old (n = 5), respectively. The patients were divided into 8 groups at the age of 8 years (n = 6). Serum and hair samples were collected and analyzed for mineral elements. The results showed that: 1) the number of ribs and age had no significant effect on the content of calcium (Ca), copper, (Cu), iron, potassium, (K), magnesium, manganese, (Mn), sodium, (Na), zinc (Zn) in serum (P0.05); There was no interaction between age and rib number (P0.05). 2) the number of ribs had no significant effect on the content of Ca,Cu,Fe,Mg,Mn,Na,Zn in coat (P0.05). The content of K in hair was significantly higher than that in other age groups (P 0.05), but had no significant effect on the content of other elements in coat (P0.05). There was no interaction between age and rib number (P0.05). 3) Ca, in coat had no interaction between age and number of ribs (P0.05). There was a significant correlation between Cu,Fe,Mg,Zn and the content of corresponding elements in serum (P0.01), the correlation coefficients were 0.623, 0.539 8, 0.569 2, 0.468 4, 0.505 3, respectively, but the correlation between K, mn, Na content was not significant (P0.05). The results showed that there was no significant difference in mineral element contents between 14 ribbed and 15 ribbed yaks in Jinchuan, but K content in coat increased significantly at 7 years old and 8 years old. The contents of Ca,Cu,Fe,M-g and Zn in serum of yak were significantly correlated, and the contents of mineral elements could be determined by hair instead of serum.
