“…They were the 10 th generation of selection breeding from 12 sires and 50 dams. The procedures of the selection experiment for the duration of fertility were described by Cheng et al (2002Cheng et al ( , 2005. The phenotype traits, consisting of the egg weight at 30 weeks of age (EW30), egg weight at 40 weeks of age (EW40), number of eggs to 40 weeks of age (EN40), hatchability rate (HR), fertility rate (FR) and maximum duration of fertility (MDF), were used for marker-trait association analysis.…”

Our previous cDNA microarray study showed that the growth hormone (GH) gene may involve in the duck egg formation process. The purpose of this study was to investigate the relationship between GH genotypes of single nucleotide polymorphisms (SNPs) and reproductive traits of Tsaiya ducks. Primer pairs for the coding region in the GH were designed based on the duck genomic sequence. Polymorphisms were detected by polymerase chain reaction (PCR)-single strand polymorphism (SSCP) and were verified by DNA sequencing. Nineteen SNPs were identified in the duck GH gene, of which three coding SNPs (C3169T, C3700T and C5058G) were genotyped to investigate the associations with reproductive traits. The results showed that each SNP was associated with at least one duck fertility-related trait (p < 0.05). Haplotypes constructed on these three SNPs were associated with fertility rate (FR) and maximum duration of fertility (MDF) (p < 0.05). In particular, diplotype H1H1 was dominant for FR and MDF. This suggested that GH gene polymorphisms are associated with duck fertility-related traits. The SNPs in this gene may be used as potential markers for marker-assisted selection.

“…The four populations were close and compact as a group that far from other populations in 3D PCA. It's perhaps all BI, BII, and BIII were derived from GBT and all were selected by only one trait, moreover their separation was not for long time, the selective programs began at 1984, 1992, and 1996 respectively [6,8,9]. Such low diversity between populations and each population would breed for a breed, the monitoring and analyzing system should be high definition.…”

“…This high egg production line was namely Brown Tsaiya LRI 1 (BI) (Figure 1B). The second line of LRI's Brown Tsaiya, that is, the Brown Tsaiya LRI 2 (BII) ( Figure 1C), originated from the fifth generation of BI and was selected to increase the number of fertile eggs after a single artificial insemination with pooled Muscovy semen since 1992 [8]. In 1996, LRI started to select the color of the egg shell from the eighth generation of BI and established a Brown Tsaiya line with blue egg shells which Taiwan people favor, called Brown Tsaiya LRI 3 (BIII) ( Figure 1D) [5,9].…”

Objective: A set of microsatellite markers with high polymorphism from Tsaiya duck were used for the genetic monitoring and genetic structure analysis of Brown and White Tsaiya duck populations in Taiwan.Methods: The synthetic short tandem repeated probes were used to isolate new microsatellite markers from the genomic DNA of Tsaiya ducks. Eight populations, a total of 566 samples, sourced from Ilan Branch, Livestock Research Institute were genotyped through novel and known markers. The population genetic variables were calculated using optional programs in order to describe and monitor the genetic variability and the genetic structures of these Tsaiya duck populations.Results: In total 24 primer pairs, including 17 novel microsatellite loci from this study and seven previously known loci, were constructed for the detection of genetic variations in duck populations. The average values for the allele number, the effective number of alleles, the observed heterozygosity, the expected heterozygosity, and the polymorphism information content were 11.29, 5.370, 0.591, 0.746, and 0.708, respectively. The results of analysis of molecular variance and principal component analysis indicated a contracting Brown Tsaiya duck cluster and a spreading White Tsaiya duck cluster. The Brown Tsaiya ducks and the White Tsaiya ducks with Pekin ducks were just split to six clusters and three clusters when K was set equal to 6 and 3 in the Bayesian cluster analysis. The individual phylogenetic tree revealed eight taxa, and each individual was assigned to its own population.Conclusion: According to our study, the 24 novel microsatellite markers exhibited a high capacity to analyze relationships of inter- and intra-population in those populations with a relatively limited degree of genetic diversity. We suggest that duck farms in Taiwan could use the new (novel) microsatellite set to monitor the genetic characteristics and structures of their Tsaiya duck populations at various intervals in order to ensure quality breeding and conservation strategies.

“…Animals and DNA preparation A total of 133 control lines (CL) with no selection and 184 duration of fertility selected line (SL) of Brown Tsaiya ducks, obtained from the LRI-COA experimental farm in Hsinhua, Tainan, were employed in this study. The detailed schedule of the selection experiment and standardized conditions of feeding and management for these lines is described in the study by Cheng et al (2005). Table 1 summarizes the least-squares means (LSM) and standard error (SE) of the phenotypic traits analysed in this study.…”

In our previous cDNA microarray study, we found that the carbonic anhydrase II (CA2) gene is one of the differentially expressed transcripts in the duck isthmus epithelium during egg formation period. The aim of this study was to identify the single-nucleotide polymorphisms (SNPs) in the CA2 gene of Tsaiya ducks. The relationship of SNP genotype with egg production and reproduction traits was also investigated. A total of 317 ducks from two lines, a control line with no selection and a selected line, were employed for testing. Three SNPs (C37T, A62G and A65G) in the 3'-untranslated region of the CA2 gene were found. SNP-trait association analysis showed that SNP C37T and A62G were associated with duck egg weight besides fertility. The ducks with the CT and AG genotypes had a 1.46 and 1.62 g/egg lower egg weight as compared with ducks with the CC and AA genotypes, respectively (p < 0.05). But the ducks with CT and AG genotypes had 5.20% and 4.22% higher fertility than those with CC and AA genotypes, respectively (p < 0.05). Diplotype constructed on these three SNPs was associated with duck fertility, and the diplotype H1H4 was dominant for duck fertility. These findings might provide the basis for balanced selection and may be used in marker-assisted selection to improve egg weight and fertility simultaneously in the Tsaiya ducks.
