针对保温法及蓄水法养护手段，论述了现场实施的测温及温度裂缝控制计算，以实现信息化施工。

To prepare recombinant fox growth hormone, we amplified its cDNA from silver fox pituitary tissue by RT-PCR and cloned into yeast shuttle vector pPIC9K down stream of α-factor signal peptide sequence by SnaB I and Not I restriction sites. The recombinant secretion vector pPIC9K/fGH, linearized by Sal I, was transformed into histidine-deficient Pichia pastoris strain GS115 by electroporation.

为制备重组狐狸生长激素，采用RT-PCR方法，从银狐垂体中扩增fGH cDNA基因，利用SnaB I和Not I位点将fGH基因插入到酵母分泌型表达载体pPIC9K中α-因子信号肽的下游，构建成fGH基因的酵母分泌型表达载体pPIC9K/fGH，载体经Sal I酶切线性化后，通过电转移将线性化的pPIC9K/fGH转化到组氨酸缺陷型酵母宿主菌GS115中。

This study mainly investigated the effect of maternal undernutrition during late pregnancy on the levels of hormones which take the somatotropic axis as the center in ewes, the expression of partil hormones'mRNA and the gene localization in tissue cells on the basis of animal nutrition, endocrine physiology and by modern molecular biology technique. The experiments explored the mechanism of restriction and compensatory in order to pave the way for applying compensatory growth for animal husbandry scientifically.

本研究依据内分泌生理学和动物营养学理论，应用现代分子生物学技术系统研究了限饲及补偿生长对母羊生长轴激素基因表达水平的影响以及部分激素在母羊组织细胞中基因表达定位规律，进一步探究了绵羊补偿生长与内分泌生长轴的关系，为更科学地将动物的补偿生长能力应用于畜牧业生产上奠定理论基础。
