Association of SNPs in ODC and PRDM16 with Body Weight Traits in Korean Native Chicken

Objective: Thyroid hormone responsive spot 14 alpha (THRSP) has been used to investigate the regulation of de novo lipogenesis because the variation of THRSP mRNA content in the tissue affects directly the ability of that tissue to synthetize lipids. Also, this gene responds to thyroid hormone stimulation and high level of carbohydrate feeding or insulin-injection. This study was carried out to investigate variations within THRSP and their effects on body and carcass weights in Korean native chicken (KNC).Methods: A total of 585 chickens which represent the five lines of KNC (Black, Gray-Brown, Red-Brown, White, and Yellow-Brown) were reared and body weight data were recorded every two weeks from hatch until 20 weeks of age. Polymerase chain reaction- restriction fragment length polymorphism, DNA chips for Agilent 2100 Bioanalyzer, and Fluidigm Genotyping Technology, were applied to genotype selected markers. A linear mixed-effect model was used to access association between these single nucleotide polymorphism (SNP) markers and growth-related traits.Results: A total of 30 polymorphisms were investigated in THRSP. Of these, nine SNPs for loci were selected to perform association analyses. Significant associations were detected between g.-49G>T SNP with body weight at 20 weeks of age (BW20), g.451T>C SNP with growth at 10 to 12 weeks of age (GR10-12), and g.1432A>C SNP with growth at 14 to 16 weeks trait (GR14-16) and body weight at 18 weeks of age (BW18). Moreover, diplotype of the THRSP gene significantly affected body weight at 12 weeks of age (BW12) and GR10-12 traits. Diplotype of ht1/ht2 was favorable for BW12 and GR10-12 traits.Conclusion: These results suggest that THRSP can be regarded as a candidate gene for growth traits in KNC.

The research was aimed to evaluate used dahlia tubersextract as inulinsource onnitrogen retention and feed conversion of crossbred local chicken (male native chicken × female laying hen). Three weeks old 160 unsex birds with average body weight 180.46±1.21g were kept until 8 weeks. The experimentwas designed ascompletely randomized design with 4 treatments and 4 replications (@10 birds). Treatments applied were T0: basal ration, T1: ration + 0.39% extract, T2: ration + 0.78% extract, T3: ration + 1.17% extract. Parameters observed werenitrogen retention, energy metabolism and feed conversion. The data were statistically analyzed according to ANOVA and continued by Duncan test at the level of 5%. The results showed that feeding dahlia tuberextract significantly affect (P<0.05) nitrogen retentionwith value T0-T3 (1.3g, 1.47g, 1.43g, 1.7g)and feed conversion (4.15, 3.58, 3.75, 3.47), but not significant of energy metabolism. In conclusion, the higher levels of feeding inulin in the form of extract in T3 (1.17%), increase nitrogen retention and improve feed conversionof crossbred local chicken.
