The plasma proteins of Beijing Ducks were determined by means of gradient polya-crylamide gel electrophoresis,and the polymorphisms in post-transferrin region, Potf 2,which was controled by two alleles,were observed. The genetic distance among somestrains was calculated according to the gene frequences of Potf2 alleles. The clusteranalysis showed that these strains could be divided into two types, which were bred assire lines and dam lines respectively in commercial production, and the gene frequencesof...

The plasma proteins of Beijing Ducks were determined by means of gradient polya-crylamide gel electrophoresis,and the polymorphisms in post-transferrin region, Potf 2,which was controled by two alleles,were observed. The genetic distance among somestrains was calculated according to the gene frequences of Potf2 alleles. The clusteranalysis showed that these strains could be divided into two types, which were bred assire lines and dam lines respectively in commercial production, and the gene frequencesof PotfZA allele of sire lines were higher than those of dam lines. The average bodywe-ight on 49-day old were compared among six strains and three genotypes of Potf2respectively. Highly significant relationship between Potf2 genotypes and bodyweightwas found. The strains with high gene frequence of Potf2A allele and the genotype ofPotfZAA had high bodyweight on 49-day old.

用连续线性梯度聚丙烯酰胺凝胶电泳技术分离北京鸭血浆蛋白,在后转铁蛋白区Potf2发现了由2个等位基因构成的3种基因型利用Potf2的基因频率计算了现有北京鸭育成品系间的遗传距离并进行了聚类分析,将北京鸭的6个品系分成两类,这两类恰好分别作杂交配套的父本和母本,其中父系的Potf2A基因的频率显著高于母系;分别统计北京鸭6个品系和3种基因型的49日龄体重并进行了多重比较,发现品系的平均体重越大等位基因Potf2A的频率越高;3种基因型中AA型的平均体重显著高于AB型和BB型。

Two lean-type pig lines, sire Duroc pigs and dam Zhijiang White pigs, were genetically selected for 4 generations. Genetic parameters of some important economic traits in the two lines were estimated and applicated in the selection. Results showed that sire line growth rate increased by 18 9%, feed conversion ratio decreased by 9 5%, average back fat thickness decreased by 18 2%, and lean meat in carcass increased by 3 5 percent. Reproductive performance for the dam line has been improved. Average...

Breeder pigs including American-lines Landrace, Large White, Duroc, Hampshire and line 24 were selected and bred by systematic ally. Continuing tests of the 6 generations selected in 10 years indicated the pigs accomplished the goals of the breeding program. Breeding pigs showed multifarious charecters, i. e. high prolificacy, fast growth rate and high production efficiency. Dam line breeder swine (Landrace and Large White) exhibited evident estrous signs, tame temperament, high conception rate,large litter...

Breeder pigs including American-lines Landrace, Large White, Duroc, Hampshire and line 24 were selected and bred by systematic ally. Continuing tests of the 6 generations selected in 10 years indicated the pigs accomplished the goals of the breeding program. Breeding pigs showed multifarious charecters, i. e. high prolificacy, fast growth rate and high production efficiency. Dam line breeder swine (Landrace and Large White) exhibited evident estrous signs, tame temperament, high conception rate,large litter size, with live birth averaging 10. 37 and 10. 86, and 21-day litter mass averaging 54. 23 and 58. 81kg, for Landrace and Large White respectively. Fast growth was expressed by sire line boars which achieved maximum daily gain of up to 1020 g during test Peried. In addition the boars also attained good performance regarding to feed conversion efficiency and leannss with lean rate reaching 65. 3%, Commereial pigs produced by cross combinations of Duroc x Landrace x Large White and Duroc x Large White x Landrace expressed high heterosis and took 165 days to reach 90 kg of market mass.
