This paper reports the results of blood-group and plasma protein polymorphism of ele-vtn Chinese native fowl breeds.1. The distribution frequencies of the blood-group genes (3 loci 12 alleles) in eleven Chinese native fowl breeds were significantly different in A and C loci, but not significant in B locus. The coefficients of homozygosity of blood-group gene in all breeds were almost similar, except in Gushi and Chonren pitted chickens. The distribution of blood-group factors in all breeds was extensive, and...

This paper reports the results of blood-group and plasma protein polymorphism of ele-vtn Chinese native fowl breeds.1. The distribution frequencies of the blood-group genes (3 loci 12 alleles) in eleven Chinese native fowl breeds were significantly different in A and C loci, but not significant in B locus. The coefficients of homozygosity of blood-group gene in all breeds were almost similar, except in Gushi and Chonren pitted chickens. The distribution of blood-group factors in all breeds was extensive, and this means that the selection potential in these local breeds was very large.2. The gene frequencies of alkaline phosphatase (Akp and Akp-2) transferrin (Tf) in some breeds were more different, while the that of esterase (Es-1) was less different. Among Chinese Japanese and American-European native breeds, the difference of gene frequencies of esterase was greater, while that of alkaline phosphatase and transferrin was smaller. It showed the identity or diversity in breed origin and evolution in these Chinese local breeds and Japanese or American-European native breeds.3. The cluster analysis of the eleven Chinese native fowl breeds showed that these breeds could be divided into four groups: White ear-lobe- Shouguang- Luyuan chickens; Xiaoshan-Xianju- Pudong chickens; Langshan- Taihe Silky- Beijing Youkei chickens and Gushi-Chonr-en pitted chickens.

对我国11个地方鸡种1087羽鸡群进行了血型和血浆蛋白质多态7个位点22个等位基因的群体遗传学分析。结果表明,血型A、C位点,基因频率各鸡种存在显著差异,B位点则没有显著差异,血型和血浆蛋白质多态位点基因纯合系数普遍较低,血型因子分布在群体中较为分散,表明这些地方品种存在较大的选择潜力。血浆蛋白质多态位点,中国与外国的某些鸡种比较,存在着较大的相同或相异,可能意味着我国和外国鸡种起源上的同缘或品种起源、进化上的多样性。聚类分析表明,这11个地方鸡种可系统聚类成4个类群,其结果与目前人们对这些鸡种的表征分类不尽一致。

The 131I uptake rate of the thyroid in the IHG heterozygous goats was assayed. Some serum parameters of thyroid function such as total T3 (TT3), total T4 (TT4) , reverse T3 (RT3), free thyroxine index (FTI) and TSH were determined in the goats of both IHG homozy-gotes and IHG heterrozygotes. The results suggested that the 131I uptake rate of thyroid in the IHG heterozyous goats decreased significantly. In the sera the quantities of TT3, TT4, FT3I and FT4I (especially TT3 and FT3I) of both the IHG homozygotes...

The 131I uptake rate of the thyroid in the IHG heterozygous goats was assayed. Some serum parameters of thyroid function such as total T3 (TT3), total T4 (TT4) , reverse T3 (RT3), free thyroxine index (FTI) and TSH were determined in the goats of both IHG homozy-gotes and IHG heterrozygotes. The results suggested that the 131I uptake rate of thyroid in the IHG heterozyous goats decreased significantly. In the sera the quantities of TT3, TT4, FT3I and FT4I (especially TT3 and FT3I) of both the IHG homozygotes and IHG heterozygotes decreased significantly, but the quantity of TSH increased significantly. It was believed that the changes of these parameters of the thyroidal function were the biochemical phenotype character of the IHG goats. They can be used to detect the IHG heterozygous goats in the IHG goats.

本实验对内蒙古二狼山白山羊遗传性甲状腺肿(Inherited goitre,IHG)杂合子羊进行了甲状腺吸~(131)碘率测定;对IHG纯合子羊和杂合子羊进行了血清总T_3(TT_3)、总T_4(TT_4)、反T_3(rT_3)、游离甲状腺激素指数(FTI)以及促甲状腺激素(TSH)等甲状腺功能参数测定.结果表明,IHG杂合子羊的甲状腺吸~(131)碘率及吸~(131)碘速率降低(P<0.01);IHG纯合子羊和杂合子羊的血清TT_3、TT_4、FT_3I及FT_4I均显著降低(P<0.05或P<0.01),而TSH显著升高(P<0.01).据此认为,这些甲状腺功能参数(特别是TT_3和FT_3I)的改变,是山羊IHG的生化表型特征,可用于IHG基因群体中杂合子携带羊的检出.

经杂交组合试验筛选出京星201和102肉鸡的母系口型矮洛克鸡D1、D2系及其配套父系A系、H系和B系,并进行了血型和血浆蛋白质多态基因群体遗传学分析,发现凡优良杂交组合中的父系(A、H系)与母系(D1、D2系)遗传距离远。父系纯合系数较高,母系较低。这些均与实际杂交结果基本一致。
