“…Different levels of fat or possibly the fatty acid profile between diets might not be big enough to provoke the effect of fat on PRKA γ 2 gene regulation or the effect may not be present in the jejunum. Cho et al. (2017) observed that PRKA γ 2 in the muscle and cell-free plasma did not differ by feeding ducks the diets with low and medium levels of AME (2,300 and 2,900 kcal/kg diet); on the other hand, high AME level (3,300 kcal/kg diet) (with higher dietary fat) upregulated PRKA γ 2 in those tissues possibly to maintain energy homeostasis.…”

The present study was conducted to investigate the effect of feeding the different levels of the dietary fat on the expression of genes encoding proteins involving energy metabolism, oxidative phosphorylation, and lipid synthesis including peroxisome proliferator-activated receptor gamma ( PPARγ ) of laying hens in the intestine. Birds fed diets with 3 levels of fat, that is, low ( LF ), medium ( MF ), and high fat ( HF ) were reared from 22 to 42 wk of age. Jejunum tissue was collected at week 42 for gene expression analysis. Dietary fat content as ether extract, net energy to AME ratio, and CP content of 3 treatment groups were as follows: LF: 25, 0.735, 187 (g/kg, DM); MF: 61, 0.739, 185 (g/kg, DM); HF: 73, 0.752, 181 (g/kg, DM). The BW, fat pad weight (g), fat pad–to–BW ratio (%) was the same for all the treatments ( P > 0·05). Birds fed a diet containing HF increased the AME daily intake per metabolic BW (BW 0.75 ) ( P < 0.05). The expression of jejunal PPAR γ was increased in the birds fed MF than that fed LF ( P < 0.05). Dietary fat level did not affect the expression of other genes: protein kinase AMP-activated noncatalytic subunit gamma 2, NADH dehydrogenase subunit 2, succinate dehydrogenase complex flavoprotein subunit A, ubiquinol-cytochrome c reductase Rieske iron-sulfur polypeptide 1, cytochrome c oxidase subunit III, ATP synthase subunit alpha, avian adenine nucleotide translocator, and acetyl-CoA carboxylase alpha ( P > 0·05). The mitochondrial count per cell showed no difference among the 3 groups with different dietary treatments ( P > 0·05). The results suggest that PPAR γ may be important to the energy expenditure during nutrient absorption, digestion, and metabolism, and respiratory chain complexes, and other genes involving mitochondrial energy metabolism and lipogenesis may be less responsive to dietary treatment.

“…They have a high crude protein, water retention capacity, and unique meat flavor and texture with high polyunsaturated fatty acids in breast meat and high essential fatty acids, arachidonic acid [17]. Although some recent studies have investigated the unique characteristics of the Korean native duck [17][18][19][20], whole genome-level studies for the Korean native duck still lag behind other domestic animals and duck breeds.…”

Background: Advances in next-generation sequencing technologies have provided an opportunity to perform population-level comparative genomic analysis to discover unique genomic characteristics of domesticated animals. Duck is one of the most popular domesticated waterfowls, which is economically important as a source of meat, eggs, and feathers. The objective of this study is to perform population and functional analyses of Korean native duck, which has a distinct meat flavor and texture phenotype, using whole-genome sequencing data. To study the distinct genomic features of Korean native duck, we conducted population-level genomic analysis of 20 Korean native ducks together with 15 other duck breeds. Results: A total of 15.56 million single nucleotide polymorphisms were detected in Korean native duck. Based on the unique existence of non-synonymous single nucleotide polymorphisms in Korean native duck, a total of 103 genes related to the unique genomic characteristics of Korean native duck were identified in comparison with 15 other duck breeds, and their functions were investigated. The nucleotide diversity and population structures among the used duck breeds were then compared, and their phylogenetic relationship was analyzed. Finally, highly differentiated genomic regions among Korean native duck and other duck breeds were identified, and functions of genes in those regions were examined. Conclusions: This is the first study to compare the population of Korean native duck with those of other duck breeds by using whole-genome sequencing data. Our findings can be used to expand our knowledge of genomic characteristics of Korean native duck, and broaden our understanding of duck breeds.
