中文摘要：
为探索哺乳藏仔猪发育期血液指标动态变化规律及进一步对藏猪进行科学评价与开发利用，分别测定了1、7、14、21、28日龄哺乳藏仔猪的血液生化指标，并与同期（杜×长×大）三元杂交仔猪进行比较。结果表明，藏仔猪各项指标值均在小型猪的正常值范围内，其中ALP和AMM峰值均出现在7日龄，随后逐渐下降；BUN变化趋势与AMM相似，但峰值推迟到14日龄；GPT和GOT含量保持稳定；CRE含量呈极显著连续上升趋势；GLU含量在出生时最低，7日龄后保持稳定；LAC最高、最低值分别出现在7、14日龄；TG呈连续下降趋势，CHO和LDL的变化趋势相似。藏仔猪发育期AIJP、AMM、GPT和GOT含量均高于三元杂交仔猪，与其饲料利用率低，蛋白维持需要量大、肉品质好等特点相吻合；而其脂类相关指标值与人类相近，可能更适合作为人类器官移植的供体、制作心血管方面的疾病动物模型。
英文摘要：
In order to further study the serum physiological characteristics of Tibetan pigs during lactation stage and the scientific evaluation and exploitation on it,the experiment was conducted to analyze and compare the blood biochemical indicators in breast-feeding Tibetan piglets and （ Duroc × Landrace × Yordshire） crossbreed piglets with 1,7,14,21 and 28 days,respectively. The results showed that the serum indicators of breast-feeding Tibetan piglets were at range of normal values for minitype pig,and the alkaline phosphatase （ALP） and ammonemic （AMM） in serum peaked at 7 days and followed by a gradual declining trend to the minimum on 28d. It was found that serum urea nitrogen （BUN） showed a similar changing trend to AMM, but its peak delayed to 14d ,while glutamic-pyruvic transaminase （GPT） and glutamic-oxal （o） acetic transaminase （GOT） fluctuated slightly and the carnine （CRE） level had significant increase during the whole stage. The GLU concentration in serum was found to be the lowest at birth and remained stable after 7 days. The maximum and minimum values of LAC ap- peared on the 7th d and 14th d, respectively,Triglyceride in serum undergone a continuous downward trend, and there was strung correlation between cholesterol and LDL concentrations. Furthermore, the activities of ALP, AMM, GPT and GOT in serum of Tibetan piglets were higher than that of （Duroc x Landrace x Yordshire） crossbreed piglets during different stages,which was in accordance with its characteristics of lower utilization rate of feed ,higher maintenance requirements and better meat quality ,etc. The lipid-related indicators of Tibetan piglets were mere similar to human ,which may be more suitably used as human organ transplant donors and animal models for cardiovascular research.
